A milestone for new carbon-dioxide capture/clean coal technology

An innovative new process that releases the energy in coal without burning while capturing carbon dioxide, the major greenhouse gas has passed a milestone on the route to possible commercial use, scientists are reporting. Their study in the ACS journal Energy & Fuels describes results of a successful 200-hour test on a sub-pilot scale version of the technology using two inexpensive but highly polluting forms of coal.

Liang-Shih Fan and colleagues explain that carbon capture and sequestration ranks high among the approaches for reducing coal-related emissions of the carbon dioxide linked to global warming. This approach involves separating and collecting carbon dioxide before it leaves smokestacks. Fan's team has been working for more than a decade on two versions of carbon capture termed Syngas Chemical Looping (SCL) and Coal-Direct Chemical Looping (CDCL). They involve oxidizing coal, syngas or natural gas in a sealed chamber in the absence of the atmospheric oxygen involved in conventional burning. Metal compounds containing oxygen are in the chamber. They provide the oxygen for oxidation, take up coal's energy, release it as heat in a second chamber and circulate back for another run in the first chamber.

Their report describes the longest continuous operation of the CDCL test system. It operated successfully for 200 hours without an involuntary shutdown. The system used sub-bituminous and lignite coals, which are the main source of carbon dioxide emissions at U.S. coal-fired power plants. Carbon dioxide captured during operation had a purity of 99.5 percent.

Biennial mammograms best after 50, even for women with dense breasts, experts say

Mar. 19, 2013 ? Screening for breast cancer every two years appears just as beneficial as yearly mammograms for women ages 50 to 74, with significantly fewer "false positives" -- even for women whose breasts are dense or who use hormone therapy for menopause.

That is the finding of a new national study involving more than 900,000 women that was published Monday in JAMA Internal Medicine.

The same team of researchers from UC San Francisco and Seattle-based Group Health Research Institute recently reported similar results for older women ages 66 to 89.

By contrast, women in their 40s with extremely dense breasts who undergo biennial mammography are more likely to have advanced-stage and large tumors than women who undergo annual mammography -- but annual mammograms also resulted in more false positives, according to the new study from the Breast Cancer Surveillance Consortium (BCSC), the largest available screening mammography dataset in the United States. Having dense breasts means it is difficult for X-rays to pass through the breast tissue.

"Increasing age and high breast density are among the strongest risk factors for the disease," said senior author Karla Kerlikowske, MD, a professor of medicine at UCSF and a physician at the UCSF-affiliated San Francisco VA Medical Center.

Weighing the Risks and Benefits of Screening

Kerlikowske and other BCSC researchers reported in 2012 that risk factors may inform individual decisions that women make with their doctors about when to start breast cancer screening and how often to repeat it. For instance, a family history of breast cancer raises the likelihood of developing the disease but it does not increase the chances of advanced-stage tumors or large tumors.

"These individual decisions involve evaluating the balance between the benefits of screening -- detecting cancer early -- and the potential harms, such as false positives among healthy women," Kerlikowske said. "Some people who are at higher risk of disease may be more willing than those at lower risk to accept such potential harms of screening."

False positives mean that women without cancer are called back for more testing, including biopsies, ultrasounds and more mammograms.

"For women 50 to 74 years old with dense breasts who are cancer free, we estimated that more than half will be recalled for additional mammography at least once over the course of 10 years of annual screening," said study co-author Rebecca A. Hubbard, PhD, an assistant investigator at Group Health Research Institute who is also at the University of Washington School of Public Health. "Screening every other year decreases this risk by about a third. The risk of false-positive results is even higher for women who begin annual screening at age 40."

National Guidelines for Mammograms

When the U.S. Preventive Services Task Force updated its breast cancer screening guidelines in 2009, it advised women to make individual decisions with their doctor. But for average-risk women, these guidelines advised screening mammography every two years for women ages 50 to 74. The guidelines recommended that women in their 40s consider their personal values regarding the benefits and harms and then decide when to begin regular screening. The Task Force deemed evidence on risk factors other than age to be weak at that point.

The new study was designed to explore other risk factors for breast cancer, beyond age. Extremely dense breasts and taking combination hormone therapy (with estrogen and progestin, although not with estrogen alone) had already been shown to raise women's rates of advanced-stage or large tumors. The new study adds to this evidence by showing regardless of breast density or hormone use, screening every other year did not raise the likelihood of detecting advanced-stage or large tumors, compared to yearly screening.

Approximately 12 to 15 percent of women in their 40s -- and approximately 3 to 6 percent of those ages 50 to 74 -- have extremely dense breasts.

How does a woman know if her breasts are dense or extremely dense?

"It's a "Catch- 22"," said co-author Diana L. Miglioretti, PhD, a senior investigator at Group Health Research Institute who is also at the University of California at Davis. "The only standard way to determine your level of breast density is to get a mammogram. But unless your breasts are extremely dense and you have other strong risk factors, the data don't necessarily support your starting screening mammograms before age 50."

The study was supported by grants from the National Cancer Institute of the National Institutes of Health (R03 CA150007, RC2 CA148577, and P01 CA107584); the National Cancer Institute-funded Breast Cancer Surveillance Consortium (U01 CA 63740, CA86076, CA86082, CA63736, CA70013, CA69976, CA63731, and CA70040. Several state public health departments and cancer registries throughout the United States supported, in part, the collection of cancer data used in this study.

Co-authors from Group Health Research Institute are: Karen J. Wernli, PhD, Ellen S. O'Meara, PhD, and Weiwei Zhu, MS; from UCSF: Dejana Braithwaite, PhD; from the University of Vermont: Berta Geller, EdD, and Kim Dittus, MD, PhD.

Hoarding: When Did Being Buried Alive Become Good ... - Feminspire

Critically analyzing the TV you?re watching can be draining. I know that the entire point of TV is to relax, veg out, and be mindless. But with all the reality TV around these days, I don?t think that I (or anyone else, really) can afford to not analyze what they?re watching any longer.

One of my TV fascinations is ?Hoarders? and ?Hoarding: Buried Alive.? They?re on two different channels, but have the same purpose: to showcase the life of someone who is a hoarder. As is oftentimes the case, I think that ignorance is what?s truly hurting us when we watch and create shows like ?Hoarders.? When you don?t fully understand the psychology behind what is happening, it?s hard to treat the subjects as human beings as opposed to circus freaks. One of the reasons we don?t know more about hoarding is that its key characteristic is secrecy. Some statistics say there are upwards of 5 million hoarders in America, but you?d never know it.

Hoarding is defined as someone who keeps possessions compulsively. These possessions can be trash, brand new but unused items, personal possessions, thrift store finds, or even animals. The possessions take up enough room in their living space that a person can no longer use the space in the way it was intended. There are levels of hoarding, one through five, with five being the most extreme. An entire room filled with unused craft supplies but an otherwise clean house would be considered level one hoarding. A house completely filled with trash, possessions, feces, one that has no heat, water, or electricity would be considered level five hoarding.

Scientists do not completely understand what causes hoarding. Hoarding has a lot of symptoms that are similar to other mental illnesses, and it can occur alongside other illness such as depression, OCD, bipolar, and schizophrenia. Most scientists are beginning to consider hoarding as its own unique mental illness. Hoarders can display symptoms from birth or sometimes begin hoarding after a traumatic event.

Now, keeping in mind that hoarding is a mental illness, here are some things that I have witnessed while watching hoarding reality TV shows:

- ? ? ?A husband and wife whose septic system backed up and filled their hallway with 6 inches of human feces.

- ? ? ?A woman whose cat was so neglected and sick that when it was scared by the people trying to clean her house, it ran out of the house, laid down in the street and died.

- ? ? ?This same woman?s toilet was so backed up that there was a mountain of feces coming out of it.

- ? ? ?The same husband and wife duo with the sewage problem, who had a sick old cat that they had lost track of. They found the cat?s skeleton behind one of their couches.

- ? ? ?A woman who had so much stuff piled in her walk-in basement that a homeless woman was living in the basement and no one realized it until the homeless woman appeared in the kitchen.

- ? ? ?A woman whose doll collection nearly made her attic fall on top of her.

These hoarders have been victims of physical, emotional, and sexual abuse. Often they have lost someone very close to them ? a particularly heart-wrenching story is that of a teenage girl whose room is completely unlivable because she cannot deal with the death of her little brother. It can also begin because of divorce, or it can be a personality trait that has never gone away.

Regardless, hoarders should be treated with compassion and understanding. I don?t think that the TV shows really emphasize how powerless these people are in the face of their mental illness. People speak about the hoarder in question negatively ? emphasizing inflexibility, belligerence, and perceived stupidity. It consistently depicts hoarders? husbands, wives, children, and siblings crying, yelling, screaming, and arguing because they think hoarders are choosing possessions over love, when that is far from the case. The professional help, aside from the psychologist assigned to the hoarder, is generally not helpful either. They spend the majority of their time cajoling, harassing, and berating hoarders to get them to release their possessions more quickly.

If someone had a disfiguring and painful physical condition that required they get therapy and rehabilitation, would we watch a TV show about them? Would we allow them to be harassed and cajoled into getting better faster? I sincerely doubt it ? or at least hope not. Mental illness in our society is treated as if it were a personality quirk, as something that people can just ?snap out of,? that the person who is ill is in the same state of mind as those who are well.

Scientists have found that hoarders brains operate in a different way ? they view every object as valuable and oftentimes cannot comprehend how dysfunctional their lives must be to outside viewers. Some hoarders use objects as a way of literally protecting themselves from painful emotions, and removing those items can open up a floodgate of traumatizing memories they may not be prepared to deal with. But if they are treated with compassion by family, friends and a trained psychologist as well as getting rid of their things on their own timeline, hoarders have a chance to get well. Possessions and painful memories can stop running their lives.

Speaking as someone who has depression and family members with mental illness, I find this throwaway treatment of mentally ill people on TV to be deeply saddening and mildly terrifying. If our society can?t treat desperately ill hoarders with compassion and care, then what hope do I and other mentally ill people have? How can I live with peace of mind in a world that sees mental illness as something that people can force out of you in less than two weeks? How can I (or anyone) tell our stories and be taken seriously when reality TV is selling mental illness as entertainment?

Do you watching hoarding TV shows, or know anyone who has suffered from their hoarding of physical?possessions? What do you think of the way the media presents this and other illnesses? Share with us in the comments below.

Virtual Reality now: hands-on with the Oculus Rift final development kit

On a sunny Southern California afternoon, Oculus VR's founder, Palmer Luckey, its VP of Product, Nate Mitchell, its press agent, a film crew, photographers and a pair of Engadget's editors occupy a conference room in the company's Irvine headquarters. While it's the first time that most of the group has met in person, they're all here with a common interest. This assembly is gathered to take a look at what is said to be the final development hardware design of the Oculus Rift virtual reality headset. Outside of this intrigued mash-up of press and corporate executives, Oculus' heads-up headset has managed to generate a lot of buzz in a reasonably short amount of time. The original concept was constructed from leftover parts in the garage of a tinkerer who was trying to create an affordable VR experience. Looking to further the Rift's development, the newborn firm took to crowdfunding and smashed its 30-day Kickstarter goal of $250,000 by raising a colossal $2,437,429 this past August.

During its early fundraising days we managed to go hands-on with a crude prototype of the equipment which left us yearning to get our hands on a final development model. A few short months later at CES, the company teased a larger, redesigned 7-inch development model, but only allowed us to try out an updated test unit that featured a 5.6-inch, 1,280 x 800 display wrapped in several layers of black gaffer tape. Fast-forward to today and here I am waiting to test-drive that elusive headset that got away from us back in Las Vegas. With all of the buzz surrounding the company's recent VR efforts, it's time for Oculus to put up or shut up.

Tourist-fed stingrays change their ways

Mar. 18, 2013 ? Stingrays living in one of the world's most famous and heavily visited ecotourism sites -- Stingray City/Sandbar in the Cayman Islands -- have profoundly changed their ways, raising questions about the impact of so-called "interactive ecotourism" on marine wildlife, reports a new study published March 18 in the journal PLOS ONE.

Researchers from Nova Southeastern University's Guy Harvey Research Institute in Hollywood, Fla. and the University of Rhode Island studied the southern stingray population of Stingray City -- a sandbar in the Cayman Islands that draws nearly a million visitors each year to feed, pet and swim with its stingrays -- to assess how the intensive ecotourism has affected the animals' behavior.

"Measuring that impact is important because there's a lot of interest in creating more of these interactive ecotourism operations, but we know little about the life histories of the animals involved or how they might change," said study co-author Guy Harvey, who initiated the project.

The researchers found that Stingray City's stingrays show distinctly different patterns of activity than their wild counterparts, who don't enjoy daily feedings or close human contact.

"We saw some very clear and very prominent behavioral changes, and were surprised by how these large animals had essentially become homebodies in a tiny area," said study co-author Mahmood Shivji, director of the Guy Harvey Research Institute and NSU Oceanographic Center professor, who led the study.

Wild stingrays are active at night and solitary -- they forage through the night over large distances to find food, and rarely cross paths with other stingrays. To see if Stingray City's fed stingrays stray from this behavior, Mark Corcoran, lead author of the study who did the research as part of his graduate work at NSU, and the research team tagged and monitored both wild and fed stingrays over the course of two years and compared their patterns of movement.

They found that fed stingrays swapped their normal nighttime foraging for daytime feeding, and in contrast to their wild counterparts, began to rest at night. They also didn't mind rubbing shoulders with their neighbors: At least 164 stingrays abandoned the species' normal solitary behavior, crowding together in less than a quarter square mile of space at Stingray City. They even formed schools and fed together. The fed stingrays mated and became pregnant year-round, instead of during a specific mating season, and also showed signs of unusual aggression, biting each other more frequently than their wild counterparts.

These results suggest that human-provided food can dramatically change how even large, highly mobile ocean animals behave -- with potentially serious consequences, the researchers conclude.

"There are likely to be some health costs that come with these behavior changes, and they could be detrimental to the animals' well-being in the long term," Shivji said. Stingray City means big business in the Cayman Islands, where each stingray generates as much as $500,000 annually in tourism income, Harvey said. The team plans to continue to monitor Stingray City's population to track its health -- and the industry's impact -- over time.

"Right now, these animals have no protection at all," Harvey said. "Without more studies like these, we won't know what that means for the wildlife or if we need to take action. It's unclear how much of the stingray's daily diet comes from tourism provided food, but the good news is we have seen the animals forage when tourists are absent suggesting that these animal are not completely dependent on these handouts."

Bow Wow Ordered to Pay French Porn Star $80,000 | News, Movies ...

Bow Wow has to cough up nearly $80,000 to a French porn star ?. for allegedly jacking footage of her dancing and splashing it all over one of his videos without her permission ? TMZ has learned. Adult film star Celine Tran ? known as ?Katsuni? ? sued Bow Wow back in July 2012, claiming he stole clips of her pole dancing in a music video for a French band called Electronic Conspiracy and then used a ton of the footage in his music video ?Drank in My Cup?

Bow Wow didn?t even respond to the lawsuit, so a federal judge ordered him to pony up $79,346.07 (damages + attorneys? fees) ? and stop with the footage STAT.

Oxygen-poor 'boring' ocean challenged evolution of early life

Mar. 18, 2013 ? A research team led by biogeochemists at the University of California, Riverside has filled in a billion-year gap in our understanding of conditions in the early ocean during a critical time in the history of life on Earth.

It is now well accepted that appreciable oxygen first accumulated in the atmosphere about 2.4 to 2.3 billion years ago. It is equally well accepted that the build-up of oxygen in the ocean may have lagged the atmospheric increase by well over a billion years, but the details of those conditions have long been elusive because of the patchiness of the ancient rock record.

The period 1.8 to 0.8 billion years ago is of particular interest because it is the essential first chapter in the history of eukaryotes, which are single-celled and multicellular organisms with more complex cellular structures compared to prokaryotes such as bacteria. Their rise was a milestone in the history of life, including that of animals, which first appear around 0.6 to 0.7 billion years ago.

The most interesting thing about the billion-year interval is that despite the rise of oxygen and eukaryotes, the first steps forward were small and remarkably unchanging over a very long period, with oxygen likely remaining low in the atmosphere and ocean and with marine life dominated by bacteria rather than diverse and large populations of more complex eukaryotes. In fact, chemical and biological conditions in this middle age of Earth history were sufficiently static to earn this interval an unflattering nickname -- 'the boring billion.'

But lest it be thought that such a 'boring' interval is uninteresting, the extraordinary circumstances required to maintain such biological and chemical stasis for a billion years are worthy of close study, which is what motivated the UC Riverside-led team.

By compiling data for metals with very specific and well-known chemical responses to oxygen conditions in the ocean, emphasizing marine sediments from this critical time interval from around the world, the researchers revealed an ancient ocean that was oxygen-free (anoxic) and iron-rich in the deepest waters and hydrogen sulfide-containing over limited regions on the ocean margins.

"Oxygen, by contrast, was limited, perhaps at very low levels, to the surface layers of the ocean," said Christopher T. Reinhard, the first author of the research paper and a former UC Riverside graduate student. "What's most unique about our study, however, is that by applying numerical techniques to the data, we were able to place estimates, for the first time, on the full global extent of these conditions. Our results suggest that most of the deep ocean was likely anoxic, compared to something much less than 1 percent today."

Study results appear online this week in the Proceedings of the National Academy of Sciences.

"A new modeling approach we took allowed us to build on our past work, which was mostly limited to defining very localized conditions in the ancient ocean," Reinhard said. "The particular strength of the method lies in its ability to define chemical conditions on the seafloor that have long since been lost to plate tectonic recycling."

Reinhard, now a postdoctoral fellow at Caltech and soon to be an assistant professor at Georgia Institute of Technology, explained that chromium and molybdenum enrichments in ancient organic-rich sedimentary rocks, the focus of the study, actually track the amount of the metals present in ancient seawater. Critically, those concentrations are fingerprints of global ocean chemistry.

Beyond the utility of chromium and molybdenum for tracking oxygen levels in the early ocean, molybdenum is also a bioessential element critical in the biological cycling of nitrogen, a major nutrient in the ocean.

"Molybdenum's abundance in our ancient rocks is also a direct measure of its availability to early life," said Timothy W. Lyons, a professor of biogeochemistry at UCR and the principal investigator of the research project. "Our recent results tell us that poor supplies of molybdenum and their impact on nitrogen availability may have limited the rise of oxygen in the ocean and atmosphere and the proliferation of eukaryotic life. There is more to do, certainly, but this is a very tantalizing new read of a chapter in Earth history that is anything but boring."

How to keep energy levels high

If you want to have high energy levels, you need to keep a healthy diet.

What works for me is
taking a multi vitamin and a vitamin c every morning

having a whey protein shake 2 times a day

working out (stay active, lift weights, it boosts your testosterone and will relieve stress)

AVOID PROCESSED FOODS (Greasy deep fried bullshit, McDonalds, wendys etc)
Seriously the preservatives they put in that shit is actually cancerous and really fucking bad.

Also, have a lot of fruits and vegtables (spinach >>>> salad fyi)

Back in HS I used to binge on unmentionables for ADD for days and I would feel like SHITTT after, but after I started this diet comedowns aren't nearly as bad and you always have more energy, feel happier etc.

IK this lifestyle sounds like shit,but seriously consider this diet though, after a couple weeks junk food just looks fucking nasty and healthy organics are really appealing (believe it or not, lol)

good luck at your job man! peace
