Army says no to more tanks, but Congress insists

WASHINGTON (AP) ? Built to dominate the enemy in combat, the Army's hulking Abrams tank is proving equally hard to beat in a budget battle.

Lawmakers from both parties have devoted nearly half a billion dollars in taxpayer money over the past two years to build improved versions of the 70-ton Abrams.

But senior Army officials have said repeatedly, "No thanks."

It's the inverse of the federal budget world these days, in which automatic spending cuts are leaving sought-after pet programs struggling or unpaid altogether. Republicans and Democrats for years have fought so bitterly that lawmaking in Washington ground to a near-halt.

Yet in the case of the Abrams tank, there's a bipartisan push to spend an extra $436 million on a weapon the experts explicitly say is not needed.

"If we had our choice, we would use that money in a different way," Gen. Ray Odierno, the Army's chief of staff, told The Associated Press this past week.

Why are the tank dollars still flowing? Politics.

Keeping the Abrams production line rolling protects businesses and good paying jobs in congressional districts where the tank's many suppliers are located.

If there's a home of the Abrams, it's politically important Ohio. The nation's only tank plant is in Lima. So it's no coincidence that the champions for more tanks are Rep. Jim Jordan and Sen. Rob Portman, two of Capitol's Hill most prominent deficit hawks, as well as Democratic Sen. Sherrod Brown. They said their support is rooted in protecting national security, not in pork-barrel politics.

"The one area where we are supposed to spend taxpayer money is in defense of the country," said Jordan, whose district in the northwest part of the state includes the tank plant.

The Abrams dilemma underscores the challenge that Defense Secretary Chuck Hagel faces as he seeks to purge programs that the military considers unnecessary or too expensive in order to ensure there's enough money for essential operations, training and equipment.

Hagel, a former Republican senator from Nebraska, faces a daunting task in persuading members of Congress to eliminate or scale back projects favored by constituents.

Federal budgets are always peppered with money for pet projects. What sets the Abrams example apart is the certainty of the Army's position.

Sean Kennedy, director of research for the nonpartisan Citizens Against Government Waste, said Congress should listen when one of the military services says no to more equipment.

"When an institution as risk averse as the Defense Department says they have enough tanks, we can probably believe them," Kennedy said.

Congressional backers of the Abrams upgrades view the vast network of companies, many of them small businesses, that manufacture the tanks' materials and parts as a critical asset that has to be preserved. The money, they say, is a modest investment that will keep important tooling and manufacturing skills from being lost if the Abrams line were to be shut down.

The Lima plant is a study in how federal dollars affect local communities, which in turn hold tight to the federal dollars. The facility is owned by the federal government but operated by the land systems division of General Dynamics, a major defense contractor that spent close to $11 million last year on lobbying, according to the nonpartisan Center for Responsive Politics.

The plant is Lima's fifth-largest employer with close to 700 employees, down from about 1,100 just a few years ago, according to Mayor David Berger. But the facility is still crucial to the local economy. "All of those jobs and their spending activity in the community and the company's spending probably have about a $100 million impact annually," Berger said.

Jordan, a House conservative leader who has pushed for deep reductions in federal spending, supported the automatic cuts known as the sequester that require $42 billion to be shaved from the Pentagon's budget by the end of September. The military also has to absorb a $487 billion reduction in defense spending over the next 10 years, as required by the Budget Control Act passed in 2011.

Still, said Jordan, it would be a big mistake to stop producing tanks.

"Look, (the plant) is in the 4th Congressional District and my job is to represent the 4th Congressional District, so I understand that," he said. "But the fact remains, if it was not in the best interests of the national defense for the United States of America, then you would not see me supporting it like we do."

The tanks that Congress is requiring the Army to buy aren't brand new. Earlier models are being outfitted with a sophisticated suite of electronics that gives the vehicles better microprocessors, color flat panel displays, a more capable communications system, and other improvements. The upgraded tanks cost about $7.5 million each, according to the Army.

Out of a fleet of nearly 2,400 tanks, roughly two-thirds are the improved versions, which the Army refers to with a moniker that befits their heft: the M1A2SEPv2, and service officials said they have plenty of them. "The Army is on record saying we do not require any additional M1A2s," Davis Welch, deputy director of the Army budget office, said this month.

The tank fleet, on average, is less than 3 years old. The Abrams is named after Gen. Creighton Abrams, one of the top tank commanders during World War II and a former Army chief of staff.

The Army's plan was to stop buying tanks until 2017, when production of a newly designed Abrams would begin. Orders for Abrams tanks from U.S. allies help fill the gap created by the loss of tanks for the Army, according to service officials, but congressional proponents of the program feared there would not be enough international business to keep the Abrams line going.

This pause in tank production for the U.S. would allow the Army to spend its money on research and development work for the new and improved model, said Ashley Givens, a spokeswoman for the Army's Ground Combat Systems office.

The first editions of the Abrams tank were fielded in the early 1980s. Over the decades, the Abrams supply chain has become embedded in communities across the country.

General Dynamics estimated in 2011 that there were more than 560 subcontractors throughout the country involved in the Abrams program and that they employed as many as 18,000 people. More than 40 of the companies are in Pennsylvania, according to Sen. Robert Casey, D-Pa., also a staunch backer of continued tank production.

A letter signed by 173 Democratic and Republican members of the House last year and sent to then-Defense Secretary Leon Panetta demonstrated the depth of bipartisan support for the Abrams program on Capitol Hill. They chided the Obama administration for neglecting the industrial base and proposing to terminate tank production in the United States for the first time since World War II.

Portman, who served as President George W. Bush's budget director before being elected to the Senate, said allowing the line to wither and close would create a financial mess.

"People can't sit around for three years on unemployment insurance and wait for the government to come back," Portman said. "That supply chain is going to be much more costly and much more inefficient to create if you mothball the plant."

Pete Keating, a General Dynamics spokesman, said the money from Congress is allowing for a stable base of production for the Army, which receives about four tanks a month. With the line open, Lima also can fill international orders, bringing more work to Lima and preserving American jobs, he said.

Current foreign customers are Saudi Arabia, which is getting about five tanks a month, and Egypt, which is getting four. Each country pays all of their own costs. That's a "success story during a period of economic pain," Keating said.

Still, far fewer tanks are coming out of the Lima plant than in years past. The drop-off has affected companies such as Verhoff Machine and Welding in Continental, Ohio, which makes seats and other parts for the Abrams. Ed Verhoff, the company's president, said his sales have dropped from $20 million to $7 million over the past two years. He's also had to lay off about 25 skilled employees and he expects to be issuing more pink slips in the future.

"When we start to lose this base of people, what are we going to do? Buy our tanks from China?" Verhoff said.

Steven Grundman, a defense expert at the Atlantic Council in Washington, said the difficulty of reviving defense industrial capabilities tends to be overstated.

"From the fairly insular world in which the defense industry operates, these capabilities seem to be unique and in many cases extraordinarily high art," said Grundman, a former deputy undersecretary of defense for industrial affairs and installations during the Clinton administration. "But in the greater scope of the economy, they tend not to be."

Keeping an ex as a friend? - Empty Closets - A safe online ...

Hey, I'm new around EC. =) This is probably going to be a long post, so I apologize in advance, and I'll try not to add too many personal details. I'd really appreciate some outside perspective on this... There is a tl;dr section at the bottom, too, just in case.

I'm a freshman in college, about to finish the school year. Last semester, I started the year with the intention of focusing on my studies, without planning on getting involved in any romance. But about halfway through the semester, one of my close college friends told me he liked me, and I thought he was a sweet guy, so I agreed to date him. Once I let myself really look at him, I fell for him hard, and quickly. He seemed like such a sweet, deep guy.

He was my first serious relationship, and what I felt for him was the deepest connection I have ever felt with another human being, and it caught me by surprise. So by the end of the first semester (during finals week, I should add... I'm really not proud of that, haha) I gave him my virginity. He was always more physically expressive than I was, and that was what he wanted, so I wanted him to have it. I never let him know it, but giving him that part of me was a particularly big deal for me, because I have some deep trust issues.

I never really enjoyed it much, until the last night before winter break, when I was finally able to relax with him (despite the fact that he was drunk, which upset me). But just as I was about to leave for my dorm, he told me that his hall mates called me his "fuck buddy." At this point in our relationship, neither of us was entirely sure if the other person wanted more than a friends with benefits relationship, but I knew I definitely wanted a deep, caring relationship, and the thought of a friends with benefits relationship with him was not appealing at all. I told him that it seemed like they were right, but that I hoped we had something deeper than that. He then basically told me that the night had just been a booty call, and then during break, we had little to no contact. I was so hurt and confused... I talked to a close mutual friend about it, and she said it seemed like he didn't want that kind of relationship either.

But then when we got back from break, he came out to me and it all made sense. I was the first person he came out to. And the way he told me was so sweet, again, and I just wanted to be there for him as a really close friend, even though it really hurt. And through the process of supporting him as he came out to the rest of our friend group, it forced me to stop ignoring the part of me that has always known that I am not completely straight, either.

So you would think that after such an intense relationship, we'd be the best of friends, right? But instead, it's been really off and on. We were best friends for a few weeks, but then I'd start to feel used again, and back off, but I still love him, so I'd come back and he'd use me some more. Well, it's the last few weeks of the second semester, and I need to be focusing on finals again, but I'm too stressed out from this broken relationship. And I can't tell if my strong preference for women is because I'm actually lesbian, not bi, or if it's because of so much hurting coming from this recent breakup.

I've essentially cut him out of my life now, deleted his number from my phone and stopped talking to him, but it's really difficult because we share the same group of close friends, so we keep running into each other, every day. Meanwhile I'm not out to anyone except him and three other really close friends, and I'm trying to keep our mutual friends out of this split, and it's taking its toll on me. It should be easier to avoid him next year because I'll be living on campus, and he'll be off campus, but it still really hurts, because as much as I don't want him to keep using me selfishly, I still love him, and I can't completely convince myself that I want to cut him from my life, even though logically it's the best for both of us (or is it?).

tl;dr: I'm hopelessly confused about the place my ex should take in my life, and about my orientation.

Strengthening legumes to tackle fertilizer pollution

Apr. 23, 2013 ? The overuse of nitrogen fertilizers in agriculture can wreak havoc on waterways, health and the environment.

An international team of scientists aims to lessen the reliance on these fertilizers by helping beans and similar plants boost their nitrogen production, even in areas with traditionally poor soil quality.

Researchers from the Center of Plant Genomics and Biotechnology at the Technical University of Madrid (UPM) and the Advanced Photon Source (APS) at the U.S. Department of Energy's Argonne National Laboratory report as an advance article April 5 for the Metallomics journal of The Royal Society of Chemistry on how to use X-ray analysis to map a path to increasing the amount of nitrogen that legumes deposit into the soil.

Cultivation of legumes, the plant family that includes peas, beans, alfalfa, soybeans, and peanuts, is one of the main ways farmers add natural nitrogen to agricultural fields. Rotating bean and corn crops to take advantage of the nitrogen beans deposit in the soil has long been a global farming tradition. Legumes use iron in the soil to carry out a complex chemical process called nitrogen fixation, which collects atmospheric nitrogen and converts it into organic forms that help the plant grow. When the plant dies, the excess nitrogen is released back into to the soil to help the next crop.

But often legumes are grown in areas with iron-depleted soil, which limits their nitrogen fixation. That's where research can lend a hand. The Argonne-UPM team has created the world's first model for how iron is transported in the plant's root nodule to trigger nitrogen fixation. This is the first step in modifying the plants to maximize iron use.

"The long-term goal is to help sustainable agriculture practices and further diminish the environmental damage from overuse of nitrogen fertilizers," said Manuel Gonzalez-Guerrero, lead author of the paper from UPM. "This can be done by maximizing the delivery of essential metal oligonutrients to nitrogen-fixing rhizobia."

The research team, which included Lydia Finney and Stefan Vogt from the APS, used high-energy X-rays from the 8-BM and 2-ID-E beamlines of the APS to track the distribution of minute iron amounts in the different developmental regions of rhizobia-containing roots. This is the first high-energy X-ray analysis of plant-microbe interactions.

X-rays, such as those from the APS, provided a high sensitivity to elements and a high spatial resolution not attainable by other means. Full details can be found in the paper Iron distribution through the developmental stages of Medicago truncatula nodules.

In future studies at the APS, Gonzalez-Guerrero hopes to identify and characterize the key biological proteins responsible for iron transportation. That would give researchers targets to manipulate and screen for new legume varieties with increased nitrogen-fixation capabilities and higher nutritional value.

Review: Worst Kept Secret Fest II ? ColumbusUnderground.com

Last Saturday, musicians from all around Columbus scrambled as they poured their gear into the Dude Locker in preparation for one of Columbus? greatest DIY (and free) shows, The Worst Kept Secret Festival. A beautiful mash up of Columbus? local artists and underground rock scene, WKSF held its sophomore event with 16 bands and a handful of artists running from 4:20 pm to 1 am. They proudly and promptly delivered the music exactly at 4:20pm, just as they had promised. The show started off with a bang and never lost it?s momentum as punks and hipsters alike took their places in front of the stage with two-dollar beers in hand.

We sat down with the Coordinators of the event, Tim Sistrunk and Geoff Spall (with special appearance by Mike Folker, Owner of Secret Song records) to discuss the story behind Worst Kept Secret Fest.

Logan Miller: So to get things started, can you tell me a little about yourselves?

Tim Sistrunk: I?m Tim Sistrunk, and I co-founded the event with Geoff Spall. Around August last year we started organizing for Worst Kept Secret Fest and things fell into place by October 5th. I work for a small company in Columbus, and I don?t play any music or make any art, but I am a music enthusiast. I love this scene and the community, so everything we?ve been doing is in the name of the music and art community.

Geoff Spall: I?m Geoff Spall and I?m a college grad that plays in several bands. I co-founded WKSF with Tim last August so we could start a festival that illuminates the underground scene. We wanted to throw a free show, so this was our idea.

LM: For the people who have no idea, what is Worst Kept Secret Fest all about?

GS: For me, Worst Kept Secret Fest is about uniting bands and artists to share an audience. It?s an easier audience with free admission, and it?s mainly about being a DIY collaboration with integrity. We just want to be able to share music with as many people as possible, so we want this to be the biggest show that these bands have played. The bands we usually book are the ones who are up and coming in the underground scene. This is all about promoting a new generation of bands and artists.

TS: Crowd-sourcing and share-sourcing are things we?re very into. We?ve pulled together resources from about 60 individual artists, band members and public community enthusiasts. We?re trying to promote a ?use it, share it? type of environment with integrity and a strong work ethic to help us maintain something different.

LM: Can you share a bit about your experience coordinating such an awesome event?

TS: For me it?s been a good way to get to a lot of new people to get to know the scene. Before Worst Kept Secret Fest I last October, felt like a bystander and now I feel like an intricate part of this machine. It?s thrilling! It?s also stressful and there?s a little anxiety riding sometimes, but it?s amazing to see people come together like this.

GS: To me the most important part about this is practicing my own skills and helping other people have a platform to practice their skills. We want people to have a place where other open-minded people accept their work and help them thrive. That?s the kind of environment we want here.

Mike Folker: I?m going to chime in on this too. One of the issues with the Columbus scene is that it?s a clique scene. People in those cliques get really excited, and they do really well inside their own clique, but they?re not really comfortable outside out it. The nice thing about a show like this is that we?re reaching out to different groups and saying ?Hey! Do you wanna grow your fan base? Do you wanna get beyond the 60 people who are coming out to see you every week?? We want to make the scene more like the way Columbus was in the 80?s and 90?s when people were going out and seeing bands all the time. It?s very cool for us to do this show, but we think more events like this are going to grow the sphere of the scene.

Wife of dead bombing suspect: Husband's alleged involvement was 'absolute shock'

William Farrington / Polaris

The American wife of suspected marathon bomber Tamerlan Tsarnaev, Katherine Russell, leaving the house where he lived on Norfolk Street in Cambridge, Mass.

By Erin McClam, Staff Writer, NBC News

The American wife of the dead Boston Marathon bombing suspect is cooperating with investigators, and her husband?s alleged involvement in the attack came as an ?absolute shock,? her lawyers said Tuesday.

The lawyers would not say whether Katherine Russell, who is known as Katie and married Tamerlan Tsarnaev in 2010, had already spoken with the FBI.

"The reports of involvement by her husband and brother-in-law came as an absolute shock to them all," lawyer Miriam Weizzenbaum said, speaking of Russell?s family, according to NBC affiliate WJAR in Providence, R.I.

"As a mother, sister, daughter, wife, Katie deeply mourns the pain and loss to innocent victims," she added.

Another lawyer, Amato DeLuca, said that Russell was doing "everything she can to assist with the investigation."

Russell converted to Islam after she met her future husband at a nightclub in 2009. She dropped out of college, got married and had a baby three years ago. She has been living in Cambridge, Mass., raising the child and working as a home health aide, the lawyers said. She has also been spending time with family in Rhode Island.

Tamerlan Tsarnaev, 26, was killed after a shootout with police early Friday. His brother, Dzhokhar, 19, was captured that night, hiding in a boat in a suburban Boston driveway, after a daylong manhunt that paralyzed the Boston area.

Dzhokhar?Tsarnaev has been charged with conspiring to use a weapon of mass destruction and could face the death penalty. He was upgraded to fair condition from serious Tuesday at a Boston hospital.

The mother of the two brothers suspected of the Boston Marathon bombing has told ITV News that her sons went to the event last year. Her chilling admission comes a day after her youngest son was charged with the crime in hospital. From her home town in Dagestan, ITV's Martin Geissler reports.

Authorities said the brothers led police on a wild chase that began late Thursday. They shot and killed a college patrol officer, carjacked an SUV and engaged police in a wild, 200-shot gun battle, tossing explosives out the window of a car, authorities said.

The FBI checked out Tamerlan Tsarnaev in 2011, after the Russian government raised concerns that he might have ties to extremist groups, but turned up nothing, law enforcement officials have said.

Meanwhile, The brothers' mother, Zubeidat Tsarnaeva, told the British broadcaster ITN on Tuesday that she was aware that investigators had talked to Tamerlan in the past, and that investigators had also spoken with her.

She said she was asked, "'He?s like a leader, he?s a strong boy, and do you think that he could get involved into kind of like any organization, you know like radical organization?' At that time because they told me that they saw whatever he was reading. And I said no, no."

"What happened was a terrible thing,? the mother told ITN from Makhachkala, in southern Russia. ?But I know that my kids have nothing to do with this. I know it. I am mother. I know my kids. I know my kids."

And also late Tuesday, the suspects' sisters, Ailina and Bella Tsarnaev, who live in New Jersey, released a short statement through their lawyers, which read: "Our heart goes out the victims of last week?s bombing. It saddens us to see so many innocent people hurt after such a callous act. As a family, we are absolutely devastated by the sense of loss and sorrow this has caused. We don?t have any answers but we look forward to a thorough investigation and hope to learn more."

Grains of sand from ancient supernova found in meteorites: Supernova may have been the one that triggered the formation of the solar system

Apr. 19, 2013 ? It's a bit like learning the secrets of the family that lived in your house in the 1800s by examining dust particles they left behind in cracks in the floorboards.

By looking at specks of dust carried to earth in meteorites, scientists are able to study stars that winked out of existence long before our solar system formed.

This technique for studying the stars -- sometimes called astronomy in the lab -- gives scientists information that cannot be obtained by the traditional techniques of astronomy, such as telescope observations or computer modeling.

Now scientists working at Washington University in St. Louis with support from the McDonnell Center for the Space Sciences, have discovered two tiny grains of silica (SiO2; the most common constituent of sand) in primitive meteorites. This discovery is surprising because silica is not one of the minerals expected to condense in stellar atmospheres -- in fact, it has been called 'a mythical condensate.'

Five silica grains were found earlier, but, because of their isotopic compositions, they are thought to originate from AGB stars, red giants that puff up to enormous sizes at the end of their lives and are stripped of most of their mass by powerful stellar winds.

These two grains are thought to have come instead from a core-collapse supernova, a massive star that exploded at the end of its life.

Because the grains, which were found in meteorites from two different bodies of origin, have spookily similar isotopic compositions, the scientists speculate in the May 1 issue of Astrophysical Journal Letters, that they may have come from a single supernova, perhaps even the one whose explosion is thought to have triggered the formation of the solar system.

A summary of the paper will also appear in the Editors' Choice compilation in the May 3 issue of Science magazine.

The first presolar grains are discovered

Until the 1960s most scientists believed the early solar system got so hot that presolar material could not have survived.

But in 1987 scientists at the University of Chicago discovered miniscule diamonds in a primitive meteorite (ones that had not been heated and reworked). Since then they've found grains of more than ten other minerals in primitive meteorites.

Many of these discoveries were made at Washington University, home to Ernst Zinner, PhD, research professor in Physics at Washington University in St. Louis, who helped develop the instruments and techniques needed to study presolar grains (and the last author on the paper).

The scientists can tell these grains came from ancient stars because they have highly unusual isotopic signatures. (Isotopes are different atoms of the same chemical element that have a slightly different mass.)

Different stars produce different proportions of isotopes. But the material from which our solar system was fashioned was mixed and homogenized before the solar system formed. So all of the planets and the Sun have the pretty much the same isotopic composition, known simply as "solar."

Meteorites, most of which are pieces of asteroids, have the solar composition as well, but trapped deep within the primitive ones are pure samples of stars. The isotopic compositions of these presolar grains provide clues to the complex nuclear and convective processes operating within stars, which are poorly understood.

Even our nearby Sun is still a mystery to us; much less more exotic stars that are incomprehensibly far away.

Some models of stellar evolution predict that silica could condense in the cooler outer atmospheres of stars but others predict silicon would be completely consumed by the formation of magnesium- or iron-rich silicates, leaving none to form silica.

But in the absence of any evidence, few modelers even bothered to discuss the condensation of silica in stellar atmospheres. "We didn't know which model was right and which was not, because the models had so many parameters," said Pierre Haenecour, a graduate student in Earth and Planetary Sciences, who is the first author on the paper.

The first silica grains are discovered In 2009 Christine Floss, PhD, research professor of physics at Washington University in St. Louis, and Frank Stadermann, PhD, since deceased, found the first silica grain in a meteorite. Their find was followed within the next few years by the discovery of four more grains.

All of these grains were enriched in oxygen-17 relative to solar. "This meant they had probably come from red giant or AGB stars" Floss said.

When Haenecour began his graduate study with Floss, she had him look at a primitive meteorite that had been picked up in Antarctica by a U.S. team. Antarctica is prime meteorite-hunting-territory because the dark rocks show up clearly against the white snow and ice.

Haenecour with the NanoSIMS 50 ion microprobe he used to look for presolar grains in a primitive meteorite. The silica grain he found is too small to be seen with the unaided eye, but the microprobe can magnify it 20,000 times, to about the size of a chocolate chip.

Haenecour found 138 presolar grains in the meteorite slice he examined and to his delight one of them was a silica grain, But this one was enriched in oxygen-18, which meant it came from a core-collapse supernova, not a red giant.

He knew that another graduate student in the lab had found a silica grain rich in oxygen-18. Xuchao Zhao, now a scientist at the Institute of Geology and Geophysics in Beijing, China, found his grain in a meteorite picked up in Antarctica by the Chinese Antarctic Research Expedition.

With two specks to go on, Haenecour tackled the difficult problem of calculating how a supernova might have produced silica grains. Before it explodes, a supernova is a giant onion, made up of concentric layers dominated by different elements.

A massive star that will explode at the end of its life, a core-collapse supernova has a layered structure rather like that of an onion.

Some theoretical models predicted that silica might be produced in massive oxygen-rich layers near the core of the supernova. But if silica grains could condense there, Haenecour and his colleagues thought, they should be enriched in oxygen-16, not oxygen-18.

They found they could reproduce the oxygen-18 enrichment of the two grains by mixing small amounts of material from the oxygen-rich inner zones and the oxygen-18-rich helium/carbon zone with large amounts of material from the hydrogen envelope of the supernova.

In fact, Haenecour said, the mixing needed to produce the composition of the two grains was so similar that the grains might well come from the same supernova. Could it have been the supernova whose explosion is thought to have kick-started the collapse of the molecular cloud out of which the planets of the solar system formed?

How strange to think that two tiny grains of sand could be the humble bearers of such momentous tidings from so long ago and so far away.

Indoctrination Centers: Note Found Written by 4th Grade Student ?I ...

Earlier this year when a sixth grade lesson plan asked elementary school students to create a communist flag of America, many parents were outraged.

But don?t think for a second that it stopped there. In fact, the indoctrination of young minds supported by officials like Attorney General Eric Holder, who once suggested we must brainwash the second amendment out of American schoolchildren, continues without respite.

In Jacksonville, Florida, a fourth grade student proves, once again, that progressive leaning educators are actively working to redefine what it means to be an American.

The following note was found by the father of a student who recently attended a class in which the kids discussed the U.S. Constitution.

?I am willing to give up some of my Constitutional rights in order to be safer or more secure.?

A Florida father is furious today after finding a note written in crayon in his son?s school book bag about his constitutional rights.

?

Aaron Harvey stated that when he went through his son?s backpack that he found a note written by his son in crayon reading,?I am willing to give up some of my constitutional rights in order to be safer or more secure.?

Harvey reveals that this note was written after his son?s class had recently had a lesson about the U.S. Constitution.

?

Harvey reveals that he talked to his son about the note, who said his teacher had spoken the sentence out loud and told them to write it down. Harvey said he asked some of his son?s classmates and got a similar answer.

?

?I am strongly for proper?education, for the freedom of thought so you can form your own opinion and have your own free speech in the future? [but] the education is, ?when was the Constitution drafted, when was it ratified, why did this happen, why did we choose to do this? all these things, why did they particular choose those specific rights to be in our Bill of Rights.??

Examiner?via The Daily Sheeple

It?s one thing to educate children and expand their understanding of the various political systems. It?s a completely different matter altogether when progressive educators attempt to mold their minds without giving them the ability to think for themselves.?

Dictation without discussion is nothing more than brainwashing based on the principle of repeating the same message over and over until the target individual begins to believe it without question.

Ronald Reagan once said, ?freedom is never more than one?generation?away from extinction.?

There are millions of people right now in America who are working hard to make sure the US Constitution and our rights to life, liberty and the pursuit of happiness go the way of the dinosaurs.

A Lego Neck Strap Sets This Bricked Camera Apart From the Rest

Flickr user RGB900's Lego DSLR is far from the first bricked camera we've brought you. But damned if it isn't one of the most detailed. One of its most impressive features is a flexible neck strack, presumably made from tank tread pieces. And the inclusion of an external flash that appears to be connected via an actual Lego hotshoe is the icing on the cake. Bravo. More »

Possible tornadoes slam Missouri, Arkansas

JEFFERSON CITY, Mo. (AP) ? Storms packing rain, snow and dangerous winds raked the Midwest and spawned a possible tornado outside of St. Louis that prompted an emergency declaration from Missouri's governor.

To the north icy weather left thousands without power and prompted Minnesota Gov. Mark Dayton to call out the state Nation Guard to aid residents as the state braced for another storm system that threatened to dump several inches of wet snow Thursday.

The most violent weather was centered near the St. Louis suburb of Hazelwood late Wednesday night. The St. Louis Post-Dispatch reported early Thursday that homes and vehicles were damaged in the area. There were no immediate reports of serious injuries.

Butch Dye, a hydrometeorological technician with the National Weather Service in St. Louis, Mo., said crews would assess the damage Thursday.

"We won't be able to confirm whether it was a tornado until teams get out there tomorrow," Dye said.

Missouri Gov. Jay Nixon declared a state of emergency in response to the damage in the St. Louis region and power outages in southern Missouri. Nixon plans to survey storm damage Thursday.

In Minnesota, Gov. Dayton said the weather was taxing the resources of local and county governments, and he issued an executive order activating the guard.

The town of Worthington was using backup diesel generators to power sections of the city at a time, public utilities manager Scott Hain told Minnesota Public Radio. Roughly a quarter to a third of the city of about 13,000 people was without power at any given time, he said.

"With the generation that we have available, we are conducting rolling blackouts through the community," Hain said. "From what we're hearing from the folks that own the transmission that's down right now, is we expect that we'll be operating under this same scenario at least through the rest of today and possibly into tomorrow as well."

The National Weather Service said southwestern Minnesota could get 8 or 9 inches of snow by Thursday morning, while 8 to 14 inches was forecast for a large swath of southern Minnesota, including the Twin Cities, St. Cloud, Willmar and Mankato starting Wednesday night and into Thursday.

In Missouri and Arkansas, dangerous winds were the threat Wednesday. A tornado was reported to have touched down near Botkinburg in north-central Arkansas, said John Robinson, the warning coordination meteorologist at the National Weather Service office in North Little Rock. Four people were injured.

Residents in eastern South Dakota were hunkering down Wednesday for the second wave of a spring storm that already downed power lines and closed roads, schools and businesses. Tens of thousands of residents in that part of the state remained without power as they awaited more bad weather.

Freezing drizzle was expected to give way Wednesday night to 6 to 12 inches of snow accompanied by winds of 15 to 25 miles per hour, said Philip Schumacher, a National Weather Service meteorologist.

The weather service said the challenging weather could extend into flood-prone southeastern North Dakota, where about 3 to 5 inches of snow is expected through late Thursday.

Although it could contain at least one-quarter inch of liquid, weather service officials said it should not change the current flood forecast.

"Any additional precipitation at this stage in the game is not necessarily a good thing," said Peter Rogers, a weather service meteorologist in Grand Forks. "But we're not expecting that to have an immediate impact on the rivers either."

In Wisconsin, rain, ice and snow caused minor flooding Wednesday in areas including the Rock River at Afton and Newville, Crawfish River at Milford, Sheboygan River at Sheboygan, and Manitowoc River at Manitowoc.

Wisconsin Emergency Management spokesman Tod Pritchard said another wave of freezing rain could sweep across central Wisconsin from La Crosse to Green Bay from late Wednesday into Thursday. That rain could cause more flooding in the region.

Sensational success in patients with major depression

Wednesday, April 10, 2013

Researchers from the Bonn University Hospital implanted pacemaker electrodes into the medial forebrain bundle in the brains of patients suffering from major depression with amazing results: In six out of seven patients, symptoms improved both considerably and rapidly. The method of Deep Brain Stimulation had already been tested on various structures within the brain, but with clearly lesser effect. The results of this new study have now been published in the renowned international journal "Biological Psychiatry."

After months of deep sadness, a first smile appears on a patient's face. For many years, she had suffered from major depression and tried to end her life several times. She had spent the past years mostly in a passive state on her couch; even watching TV was too much effort for her. Now this young woman has found her joie de vivre again, enjoys laughing and travelling. She and an additional six patients with treatment resistant depression participated in a study involving a novel method for addressing major depression at the Bonn University Hospital.

Considerable amelioration of depression within days

Prof. Dr. Volker Arnd Coenen, neurosurgeon at the Department of Neurosurgery (Klinik und Poliklinik f?r Neurochirurgie), implanted electrodes into the medial forebrain bundles in the brains of subjects suffering from major depression with the electrodes being connected to a brain pacemaker. The nerve cells were then stimulated by means of a weak electrical current, a method called Deep Brain Stimulation. In a matter of days, in six out of seven patients, symptoms such as anxiety, despondence, listlessness and joylessness had improved considerably. "Such sensational success both in terms of the strength of the effects, as well as the speed of the response has so far not been achieved with any other method," says Prof. Dr. Thomas E. Schl?pfer from the Bonn University Hospital Department of Psychiatry und Psychotherapy (Bonner Uniklinik f?r Psychiatrie und Psychotherapie).

Central part of the reward circuit

The medial forebrain bundle is a bundle of nerve fibers running from the deep-seated limbic system to the prefrontal cortex. In a certain place, the bundle is particularly narrow because the individual nerve fibers lie close together. "This is exactly the location in which we can have maximum effect using a minimum of current," explains Prof. Coenen, who is now the new head of the Freiburg University Hospital's Department of Stereotactic and Functional Neurosurgery (Abteilung Stereotaktische und Funktionelle Neurochirurgie am Universit?tsklinikum Freiburg). The medial forebrain bundle is a central part of a euphoria circuit belonging to the brain's reward system. What kind of effect stimulation exactly has on nerve cells is not yet known. But it obviously changes metabolic activity in the different brain centers.

Success clearly increased over that of earlier studies

The researchers have already shown in several studies that deep brain stimulation shows an amazing and?given the severity of the symptoms? unexpected degree of amelioration of symptoms in major depression. In those studies, however, the physicians had not implanted the electrodes into the medial forebrain bundle but instead into the nucleus accumbens, another part of the brain's reward system. This had resulted in clear and sustainable improvements in about 50 percent of subjects. "But in this new study, our results were even much better," says Prof. Schl?pfer. A clear improvement in complaints was found in 85 percent of patients, instead of the earlier 50 percent. In addition, stimulation was performed with lower current levels, and the effects showed within a few days, instead of after weeks.

Method's long-term success proven

"Obviously, we have now come closer to a critical structure within the brain that is responsible for major depression," says the psychiatrist from the Bonn University Hospital. Another cause for optimism among the group of physicians is that, since the study's completion, an eighth patient has also been treated successfully. The patients have been observed for a period of up to 18 month after the intervention. Prof. Schl?pfer reports, "The anti-depressive effect of deep brain stimulation within the medial forebrain bundle has not decreased during this period." This clearly indicates that the effects are not temporary. This method gives those who suffer from major depression reason to hope. However, it will take quite a bit of time for the new procedure to become part of standard therapy.

NASA spacecraft take spring break at Mars

NASA / JPL-Caltech

This diagram illustrates the positions of Mars, Earth and the sun during a period that occurs about every 26 months, when Mars passes almost directly behind the sun from Earth's perspective. This arrangement, and the period during which it occurs, is called Mars solar conjunction.

By Mike Wall
Space.com

NASA's robotic Mars explorers are taking a cosmic break for the next few weeks, thanks to an unfavorable planetary alignment of Mars, the Earth and the sun.

Mission controllers won't send any commands to the agency's Opportunity rover, Mars Reconnaissance Orbiter (MRO) or Mars Odyssey orbiter from Tuesday?through April 26. The blackout is even longer for NASA's car-size Curiosity rover, which is slated to go solo from April 4 through May 1.

The cause of the communications moratorium is a phenomenon called a Mars solar conjunction, during which the sun comes between Earth and the Red Planet. Our star can disrupt and degrade interplanetary signals in this formation, so mission teams won't be taking any chances.

"Receiving a partial command could confuse the spacecraft, putting them in grave danger," NASA officials explain in a video posted last month by the agency's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. [The Boldest Mars Missions in History]

Opportunity and Curiosity will continue performing stationary science work, using commands already beamed to the rovers. Curiosity will focus on gathering weather data, assessing the Martian radiation environment and searching for signs of subsurface water and hydrated minerals, officials said Monday.

MRO and Odyssey will also keep studying the Red Planet from above, and they'll continue to serve as communications links between the rovers and Earth. The conjunction will also affect the European Space Agency's Mars Express orbiter, officials have said.

Odyssey will send rover data home as usual during conjunction, though the orbiter may have to relay information multiple times due to dropouts. MRO, on the other hand, entered record-only mode on April 4. The spacecraft will probably have about 52 gigabits of data to relay when it's ready to start transmitting again on May 1, MRO officials have said.

Mars solar conjunctions occur every 26 months, so NASA's Red Planet veterans have dealt with them before. This is the fifth conjunction for Opportunity, in fact, and the sixth for Odyssey, which began orbiting Mars in 2001.

But it'll be the first for Curiosity, which touched down on Aug. 5, kicking off a two-year surface mission to determine if the Red Planet has ever been capable of supporting microbial life.

"The biggest difference for this 2013 conjunction is having Curiosity on Mars," Odyssey mission manager Chris Potts, of NASA's Jet Propulsion Laboratory in Pasadena, Calif., said in a statement last month.

The engine that could get us to Mars in 30 days

Nuclear fusion, the energy source that fuels the sun and other active stars, could one day propel rockets that allow humans to go to Mars and back in 30 days, researchers say.

Fusion-powered rockets promise to solve problems of deep-space travel that have long plagued plans for manned missions to Mars ? long journeys, high costs and health risks, among them. Scientists at the University of Washington and a space-propulsion company named MSNW say they are getting to closer to creating a feasible fuel for travel to other planets.

"Using existing rocket fuels, it's nearly impossible for humans to explore much beyond Earth," John Slough, a UW research associate professor of aeronautics and astronautics, said in a statement. "We are hoping to give us a much more powerful source of energy in space that could eventually lead to making?interplanetary travel?commonplace."

Previous estimates have found that a roundtrip manned mission to Mars would require about 500 days of space travel. Slough, who is president of MSNW, and his colleagues calculated that a rocket powered by fusion would make 30- and 90-day expeditions to Mars possible.?The project is funded in part through NASA's?Innovative Advanced Concepts Program and received a second round of funding under the program in March.

For comparison, past NASA studies have centered on Mars flights that would take two years to complete, and could cost $12 billion just to launch the fuel needed for the mission, according to Slough's team.

Nuclear fusion?occurs when the nuclei of two or more atoms combine, resulting in a release of energy. The sun and other stars convert this energy into light, and the same process gives hydrogen bombs their destructive power.

But to use fusion to power a manned spacecraft, a more controlled process is needed.

Lab tests by Slough and his team suggest that nuclear fusion could occur by compressing a specially developed type of plasma to high pressure with a magnetic field. A sand-grain-sized bit of this material would have the same amount of energy as current rocket fuel, the team says.

To get this fuel to propel a rocket to?Mars, the team says a powerful magnetic field could be used to cause large metal rings (likely made of lithium) to collapse around the plasma material, compressing it to a fusion state, but only for a few microseconds. Energy from these quick fusion reactions would heat up and ionize the shell of metal formed by the crushed rings. The hot, ionized metal would be shot out of the rocket nozzle at a high speed. Repeating this process roughly every minute would propel the spacecraft, the researchers say.

Slough said the design is fairly straightforward. The next step of the team's work is to combine each of the isolated tests they've already completed successfully into a final experiment that produces fusion using this technology.

"We hope we can interest the world with the fact that fusion isn't always 40 years away and doesn't always cost $2 billion," Slough said in a statement.

Berlin's airport project delays shame Germans

In this March 14, 2013 photo, the Berlin Brandenburg International Airport (BER) Willy-Brandt-Flughafen is seen partially illuminated in Schoenefeld near Berlin. The airport, also known as Willy Brandt International Airport, named for Germany's famed Cold War leader, was supposed to have been up and running in late 2011, a sign of Berlin's transformation from Cold War confrontation line to world class capital of Europe's economic powerhouse. Instead it has become a symbol of how, even for this technological titan, things can go horribly wrong. After four publicly announced delays, officials acknowledged the airport won't be ready by the latest target: October 2013.

(AP) ? Rabbits scamper over quiet runways. Only the call of a crow disturbs the silence around a gleaming, empty terminal that should be humming with the din of thousands of passengers.

Willy Brandt International Airport, named for Germany's famed Cold War leader, was supposed to have been up and running in late 2011, a sign of Berlin's transformation from Cold War confrontation line to world class capital of Europe's economic powerhouse. Instead it has become a symbol of how, even for this technological titan, things can go horribly wrong.

After four publicly announced delays, officials acknowledged the airport won't be ready by the latest target: October 2013. To spare themselves further embarrassment, officials have refused to set a new opening date.

The saga of Berlin's new airport has turned into a national joke and a source of humiliation for a people renowned for being on time. Yet it is just the highest profile in a string of big-ticket projects ? including a concert hall in Hamburg, railway tunnels in Munich and Leipzig, a subway line in Cologne and a Stuttgart underground train station ? that have been plagued by huge cost overruns and delays.

The airport fiasco presents a staggering picture of incompetence.

German media have tracked down a list of tens of thousands of technical problems. Among them: Officials can't even figure out how to turn the lights off. Thousands of light bulbs illuminate the gigantic main terminal and unused parking lots around the clock, a massive energy and cost drain that appears to be the result of a computer system that's so sophisticated it's almost impossible to operate.

Every day, an empty commuter train rolls to the unfinished airport over an eight-kilometer-long (five-mile) stretch to keep the newly-laid tracks from getting rusty, another example of gross inefficiency. Meanwhile, hundreds of freshly planted trees had to be chopped down because a company delivered the wrong type of linden trees; several escalators need to be rebuilt because they were too short; and dozen of tiles were already broken before a single airport passenger ever stepped on them.

The airport itself points to problems with the fire safety system as the immediate cause of the delays: The fire safety system incorporates some 75,000 sprinklers, but computer programming glitches mean it's not clear whether all of these sprinklers would spray enough water during a fire. And the system's underground vent system, designed to suck away smoke, isn't working. Here, again, technology's getting in the way: It's so advanced that technicians can't figure out what's wrong with it.

Critics say that the difficulties with handling today's complex technology have been compounded by hasty, negligent work due to the intense time pressures.

Underlying these problems appears to be a culture of political dishonesty.

"Many politicians want prestigious large-scale projects to be inseparably connected with their names," said Sebastian Panknin, a financial expert with the Taxpayer's Association Germany. "To get these expensive projects started, they artificially calculate down the real costs to get permission from parliament or other committees in charge."

In addition to that, politicians at the city, state and federal levels then often come with extra demands once construction is underway, which leads to expensive modifications. In the case of the Berlin airport, said Pankin, there were about 300 ad hoc change requests by politicians which created an explosion of costs and several delays ? among them a last-minute wish to expand the terminal to include a shopping mall.

"The airport is a classic example of the incompetence of our politicians," said Sven Fandrich, a 28-year-old Berliner who works for an insurance company. "We've seen this happen with many big infrastructure projects in Germany. Nobody feels responsible. The politicians are more concerned about winning the next elections than devoting their service to the people."

Hamburg's concert hall was to have opened by 2010. Instead it's nowhere near complete and costs have more than doubled to 575 million euros. It's now due to open in 2016.

Construction on Cologne's North-South subway line began in 2004. After cost overruns and a collapse that killed two people in 2009, officials say the entire line may not be open until 2019. Costs have soared from 780 million to 1.08 billion euros.

In Leipzig, the city tunnel for commuter trains was expected to open in 2009. Construction is still not finished, and costs have jumped from 572 million to 960 million euros.

Of all the bungled projects, the Berlin airport is the biggest embarrassment.

The initial plan foresaw building a stately airport that would be financed by private investors and replace the city's two Cold War airports ? Tegel in former West Berlin and Schoenefeld in what was the communist east.

After a series of disputes with private investors, the city, state and federal governments eventually took over the airport project. In 2006, costs were estimated at 2 billion euros, but after four delays, the figure spiked to 4.4 billion euros.

Companies like Air Berlin, Germany's second biggest carrier, have been severely affected by the delays and are suing for lost revenues. Small businesses like coffee shops, restaurants, retail stores or bus operators ? who had already hired staff and invested in new stores at the airport ? are facing bankruptcy.

Twitter users asked the mayor to "please open this gate," playing off President Ronald Reagan's famous 1987 appeal to Moscow to "tear down" the Berlin Wall.

And by the time the airport finally opens, it may face a new headache.

Some aviation experts are warning that by its inauguration date, the airport will already be too small to handle the rising number of passengers. The nearly 3.9 million square foot (360,000 square meter) airport complex was designed to handle 27 million passengers. But the existing two city airports handled 25 million passengers last year ? and the city keeps attracting more visitors every year.

"The airport is too expensive, too small and too much behind time," said aviation expert Dieter Faulenbach da Costa, who recently caused a stir when he proposed that the airport ought to be torn down.

In an effort to salvage the mess, Hartmut Mehdorn, the hardnosed former boss of the German railway system with a reputation for turning around failing corporations, was named chief executive of the airport in early March.

"The whole world says: it's not possible at all," Mehdorn said when he took over. "I say: It should be possible.

"I just don't know how yet."

Research demonstrates why going green is good chemistry

Shaken, not stirred, is the essence of new research that's showing promise in creating the chemical reactions necessary for industries such as pharmaceutical companies, but eliminating the resulting waste from traditional methods. James Mack, a University of Cincinnati associate professor of chemistry, will present this research into greener chemistry on April 9, at the annual meeting of the American Chemical Society in New Orleans.

Instead of using solutions to create chemical reactions needed to manufacture products such as detergents, plastics and pharmaceuticals, Mack is using a physical catalyst high-speed ball-milling to force chemicals to come together to create these reactions. The mechanochemistry not only eliminates waste, but also is showing more success than liquids at forcing chemical reactions.

Traditional methods dating back thousands of years involve using solutions to speed up chemical reactions that are used to make products that we use every day. However, the leftover waste or solvents can often be a volatile compound, explains Mack.

Disposal and recycling is also becoming a growing and more costly challenge for companies as they follow increasing federal regulations to protect the environment. "The solvents comprise the large majority of chemicals that are handled, but the solvent doesn't do anything but serve as a mixing vehicle. For example, for every gram of pharmaceutical drug that is generated, 15 to 20 kilograms of solvent waste is generated in that process," Mack says.

"Mechanochemistry can develop new reactions that we haven't seen before, saving on waste and developing new science," Mack says.

Mack also will report on how he has used a metal reactor vial to create chemical reactions, allowing recovery of the catalyst used to make the reaction, which usually can't be achieved by using solutions. He also is exploring efforts at using natural chiral agents agents that are non-superimposable, mirror images of each other to successfully mix chemicals and eliminate waste such as oil.

Mack's research was supported by a $367,835 grant from the National Science Foundation that was awarded in 2011 and funded through 2014. His research received a highly competitive, $550,000 NSF CAREER Award in 2006. The CAREER Award is the NSF's most prestigious award in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.

"The solvents comprise the large majority of chemicals that are handled, but the solvent doesn't do anything but serve as a mixing vehicle. For example, for every gram of pharmaceutical drug that is generated, 15 to 20 kilograms of solvent waste is generated in that process," Mack says.

"Mechanochemistry can develop new reactions that we haven't seen before, saving on waste and developing new science," Mack says.

Mack also will report on how he has used a metal reactor vial to create chemical reactions, allowing recovery of the catalyst used to make the reaction, which usually can't be achieved by using solutions. He also is exploring efforts at using natural chiral agents agents that are non-superimposable, mirror images of each other to successfully mix chemicals and eliminate waste such as oil.

Mack's research was supported by a $367,835 grant from the National Science Foundation that was awarded in 2011 and funded through 2014. His research received a highly competitive, $550,000 NSF CAREER Award in 2006. The CAREER Award is the NSF's most prestigious award in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.
