Consciousness TV | 10 shocking Things You Now Realize to be True:
We are living through a time of great awakening.
The people of our world are beginning to open their eyes and realize the stunning depth of the scams and collusion taking place all around them. These scams that steal their wealth, poison them with chemicals, enslave them with financial trickery and control their minds with propaganda. These scams are the very fabric of modern government, the mainstream media, universities and so-called “science” institutions.
Here are 11 of those scams that you probably never would have believed just 2-3 years ago; but now you probably realize these are true!
Welcome to the real world, my friends. Now that we recognize the depth of the scams, let’s change things for the better.

Edinburgh scientists grow human brain cells to study mental illness
BBC News - Edinburgh scientists grow human brain cells to study mental illness:
Scientists are growing brain cells from people in families with a history of mental illness to test new treatments.
In the past, researchers have had to rely on brain tissue from deceased donors to study conditions such as schizophrenia and bipolar disorder.
Using living cells from the skin or hair of people who have faulty genes will allow researchers to create more accurate tests.
It also means they can reduce the reliance on animal testing.
The Edinburgh University project has received a £1m funding boost from the National Centre for the Replacement, Refinement and Reduction of Animals in Research.
It aims to develop cell-based systems derived from the skin or hair of affected patients.

'Chemo brain' may persist years after treatment
'Chemo brain' may persist years after treatment | Fox News:
Women on chemotherapy for breast cancer may have tiny memory and thinking impairments compared with cancer-free women more than 20 years after their treatment, Dutch researchers have found.
Previous studies have suggested some women may experience "chemo brain" during or after treatment, but the new report is the first to test them so many years out, researchers said.
Still, the findings can't prove that chemotherapy itself is to blame for any changes in mental dexterity, and the differences in women who'd received the cell-killing treatment were "subtle."
"These are not people who are showing signs of what we would consider to be serious cognitive impairment or even mild cognitive impairment necessarily, they simply are scoring a little bit lower" on thinking and memory tests, said Barbara Collins, a neuropsychologist who has studied chemotherapy-related cognitive changes at Ottawa Hospital in Ontario, Canada.

Internet Freedom Fighters Build a Shadow Web
Internet Freedom Fighters Build a Shadow Web - Indymedia Ireland:
Governments and corporations have more control over the Internet than ever. Now digital activists want to build an alternative network that can never be blocked, filtered or shut down
• The Internet was designed to be a decentralized system: every node should connect to many others. This design helped to make the system resistant to censorship or outside attack.
• Yet in practice, most individual users exist at the edges of the network, connected to others only through their Internet service provider (ISP). Block this link, and Internet access disappears.
• An alternative option is beginning to emerge in the form of wireless mesh networks, simple systems that connect end users to one another and automatically route around blocks and censors.
• Yet any mesh network needs to hit a critical mass of users before it functions well; developers must convince potential users to trade off ease of use for added freedom and privacy.

How monster black holes are kept in check by 220,000,000mph streams of plasma
How monster black holes are kept in check by 220,000,000mph streams of plasma | Mail Online:
Black holes – and indeed the galaxies they’re found in – are reined in by huge streams of highly ionised plasma, researchers have discovered.
Francesco Tombesi from Nasa's Goddard Space Flight Center in Greenbelt, using data gathered from the European Space Agency’s XMM-Newton X-ray Observatory, has discovered that these streams, called ‘ultra-fast outflows’ exert a massive influence on the number of stars in galaxies and the size of black holes at their centre.
The study follows a baffling observation from astronomers in recent years – that there was a strong correlation between the mass of a black hole and the number of stars in the entire galaxy.

Dark World of Online Trolling Revealed
Dark world of trolling revealed | Information, Gadgets, Mobile Phones News & Reviews | Herald Sun:
BEN spends up to 70 hours a week on the internet getting high on other people's anger and despair.
The unemployed 19-year-old from Victoria - who spoke to news.com.au on the condition of anonymity - doesn't go out much and doesn't have many real friends, but he doesn't feel alone. He believes he's part of a community of similar-minded people who scour the web looking for pages to vandalise and lives to upset.
Ben (not his real name) first started trolling in 2008 on the online forum 4Chan.
His first act was innocuous enough: he weighed in on a discussion about religion and claimed to have disproved everything people had written.
Since then his trolling has become more vicious and destructive.
"It just makes me happy when I can make someone angry. It sounds weird but I kind of feed off their anger. The angrier I can get them, the better I feel," he told news.com.au.

Quest for Quirky Quantum Particles May Have Struck Gold: Scientific American | Digg Science:
Getting into nanoscience pioneer Leo Kouwenhoven's talk at the American Physical Society's March meeting in Boston, Massachusetts, today was like trying to board a subway train at rush hour. The buzz in the corridor was that Kouwenhoven's group, based at the Delft University of Technology in the Netherlands, might have beaten several competing teams in solid-state physics -- and the community of high-energy physicists -- to a long-sought goal, the detection of Majorana fermions, mysterious quantum-mechanical particles that may have applications in quantum computing.

Rich People More Likely to Lie, Cheat, Study Suggests
Rich People More Likely to Lie, Cheat, Study Suggests - Technology & science - Science - LiveScience - msnbc.com:
The cream of society may rise to the top, but so might the scum — researchers now find that people in the upper crust may be more likely to engage in lying, cheating and other kinds of unethical activity than those in lower classes.
These new findings do not mean that everyone of high status behaves unethically, nor that everyone in lower society behaves ethically, scientists cautioned.
"We're not saying that if you're rich, you're necessarily unethical, and that if you're poor, you're necessarily ethical — there are lots of instances of increased ethical conduct among upper-class individuals, such as the tremendous philanthropy of Warren Buffett or Bill Gates," said researcher Paul Piff, a social psychologist at the University of California, Berkeley.

Nature Editorial: If you want reproducible science, the software needs to be open source
Nature Editorial: If you want reproducible science, the software needs to be open source:
Modern scientific and engineering research relies heavily on computer programs, which analyze experimental data and run simulations. In fact, you would be hard-pressed to find a scientific paper (outside of pure theory) that didn’t involve code in some way. Unfortunately, most code written for research remains closed, even if the code itself is the subject of a published scientific paper. According to an editorial in Nature, this hinders reproducibility, a fundamental principle of the scientific method.
Reproducibility refers to the ability to repeat some work and obtain similar results. It is especially important when the results are unexpected or appear to defy accepted theories (for example, the recent faster-than-light neutrinos). Scientific papers include detailed descriptions of experimental methods—sometimes down to the specific equipment used—so that others can independently verify results and build upon the work.
Reproducibility becomes more difficult when results rely on software. The authors of the editorial argue that, unless research code is open sourced, reproducing results on different software/hardware configurations is impossible. The lack of access to the code also keeps independent researchers from checking minor portions of programs (such as sets of equations) against their own work.

World's smallest radio stations: Two molecules communicate via single photons:
We know since the dawn of modern physics that although events in our everyday life can be described by classical physics, the interaction of light and matter is down deep governed by the laws of quantum mechanics. Despite this century-old wisdom, accessing truly quantum mechanical situations remains nontrivial, fascinating and noteworthy even in the laboratory. Recently, interest in this area has been boosted beyond academic curiosity because of the potential for more efficient and novel forms of information processing.

Incompetent People Too Ignorant to Know It
Incompetent People Too Ignorant to Know It
A growing body of psychology research shows that incompetence deprives people of the ability to recognize their own incompetence. To put it bluntly, dumb people are too dumb to know it. Similarly, unfunny people don't have a good enough sense of humor to tell.
This disconnect may be responsible for many of society's problems.
With more than a decade's worth of research, David Dunning, a psychologist at Cornell University, has demonstrated that humans find it "intrinsically difficult to get a sense of what we don't know." Whether an individual lacks competence in logical reasoning, emotional intelligence, humor or even chess abilities, the person still tends to rate his or her skills in that area as being above average.

Are Rich People Unethical? - Yahoo! News:
At last, an explanation for Wall Street's disgrace, Bernard Madoff's Ponzi scheme and other high-society crimes and misdemeanors: A new study published in the Proceedings of that National Academy of Sciences found that wealthier people were more apt to behave unethically than those who had less money.
Scientists at the University of California at Berkeley analyzed a person's rank in society (measured by wealth, occupational prestige and education) and found that those who were richer were more likely to cheat, lie and break the law than those who were poorer.
"We found that it is much more prevalent for people in the higher ranks of society to see greed and self-interest … as good pursuits," said Paul Piff, lead author of the study and a doctoral candidate at Berkeley. "This resonates with a lot of current events these days."

Stratfor Emails Published By WikiLeaks Reveal Private Intelligence
Stratfor Emails Published By WikiLeaks Reveal Private Intelligence:
WikiLeaks said Monday it was publishing a massive trove of leaked emails from the geopolitical analysis firm Stratfor, shedding light on the inner workings of the Texas-based think tank that bills itself as a leading provider of global intelligence to a range of clients.
The online anti-secrecy group said it had more than 5 million Stratfor emails and it was putting them out in collaboration with two dozen international media organizations.
The small selection so-far published to WikiLeaks' website gave a rare look at the daily routine at a private intel firm: One described a $6,000-a-month payment made to a Middle Eastern source, another carried bits of gossip dropped by a retired spook, and many were filled with off-color office banter.

Lethal effects of genetically modified Bt toxin confirmed on young ladybird larvae:
Swiss researchers of the Swiss Federal Institute of Technology (ETH) in Zürich confirm earlier findings that the Bacillus thuringiensis (Bt) toxin Cry1Ab produced for pesticidal purposes by genetically modified (GM) Bt maize increases mortality in the young ladybird larvae (Adalia bipunctata L., two-spotted ladybird) in laboratory tests. These ladybird larvae are typical 'non-target' environmental goods which are not supposed to be harmed by the GM maize.(1)

Contrary to the common perception among physicians that poor people sue doctors more frequently, Ramon L. Jimenez from the Monterey Orthopaedic and Sports Medicine Institute and his team demonstrate that socioeconomically disadvantaged patients, in fact, tend to sue physicians less often. Their work suggests that this myth may exist because of subconscious prejudices or stereotypes that affect thinking and decision making without doctors being aware of it -- a phenomenon known as unconscious bias.

7 Dangerous Lies About Plastic
7 Dangerous Lies About Plastic | | AlterNet:
Nearly everything we consume or even interact with these days is made of plastic. The industry that produces plastic, largely represented by the American Chemistry Council (ACC), has an annual budget of over $120 million to protect its interests. But as the plague of plastic that wreaks havoc on our environment slowly gains the attention of policymakers, concerned citizens and the media, the makers of plastic resins and the companies that package their products have become increasingly aggressive about defending their respective bottom lines.
Taking tactics from Big Tobacco's playbook, the industry engages in bully tactics, politician buys and wide-scale misinformation campaigns meant to confuse the public and turn truth to speculation. Big Plastic is big money and survives regulatory scrutiny by creating big spin.
Because of slashed budgets to regulatory agencies, little private-sector money for watchdogging industry, and a lazy mainstream press that simply regurgitates its claims, the petrochemical industry goes largely unchecked. Here are some of the biggest whoppers.

Women wearing red send signals that attract men
Women wearing red send signals that attract men | Digg Science:
It seems men really do prefer the lady in red.
A new study has found that men are more attracted to women wearing red compared to other colours because they believe they are less likely to be rejected.
Psychologists behind the research claim the colour red carries subtle but powerful messages about how receptive a woman might be to romantic advances and so men find it more alluring.
The findings might explain why women in red dresses have become such a provocative image in modern culture, inspiring Chris de Burgh's 1986 love song The Lady in Red.
The researchers found that men who were shown photographs of women wearing a red shirt found them more attractive compared to when they saw the same women wearing green or white garments.

Squeezing what hasn't been squeezed before: Another victory over uncertainty in quantum physics measurements
Squeezing what hasn't been squeezed before: Another victory over uncertainty in quantum physics measurements:
Most people attempt to reduce the little uncertainties of life by carrying umbrellas on cloudy days, purchasing automobile insurance or hiring inspectors to evaluate homes they might consider purchasing. For scientists, reducing uncertainty is a no less important goal, though in the weird realm of quantum physics, the term has a more specific meaning.
For scientists working in quantum physics, the Heisenberg Uncertainty Principle says that measurements of properties such as the momentum of an object and its exact position cannot be simultaneously specified with arbitrary accuracy. As a result, there must be some uncertainty in either the exact position of the object, or its exact momentum. The amount of uncertainty can be determined, and is often represented graphically by a circle showing the area within which the measurement actually lies.

Why Synthetic Marijuana Is More Dangerous Than the Real Thing
Why Synthetic Marijuana Is More Dangerous Than the Real Thing
Synthetic marijuana, or "fake" pot, is nothing like the real thing. It's legal, and easily accessible to kids. It's also a bigger threat to kids' health. "Marijuana has been used for medicinal and recreational purposes for hundreds of years," said Dr. Jeff Lapoint, a senior toxicology fellow at New York University, Bellevue Hospital. "It's been abused, but no one really gets sick." "Kids need to know that this substance is more dangerous," Lapoint said. Popularly called K2, or Spice, synthetic marijuana is a chemical similar to cannabis that gives a marijuana-like high. But there have been an increasing number of cases of people experiencing seizures, heart palpitations, fever, dehydration and some psychotic episodes after using the drug.

High-Altitude Surveillance Drones: Coming to a Sky Near You
High-Altitude Surveillance Drones: Coming to a Sky Near You
Last week President Obama signed a sweeping aviation bill that, among other things, will open the skies to “unmanned aircraft systems,” more commonly known as drones. Much of the discussion regarding the coming era of domestic drones has been focused on the many important questions regarding their use at low altitudes. To what extent will it be legal, for example, for drones to hover 300 feet above residential neighborhoods snapping pictures into backyards and windows? What level of human-in-the-loop control is needed to ensure safety in a crowded airspace? And how can we stop terrorists from piloting drones at treetop level towards a target?

Blood mystery solved: Two new blood types identified
Blood mystery solved: Two new blood types identified:
You probably know your blood type: A, B, AB or O. You may even know if you're Rhesus positive or negative. But how about the Langereis blood type? Or the Junior blood type? Positive or negative? Most people have never even heard of these.
Yet this knowledge could be "a matter of life and death," says University of Vermont biologist Bryan Ballif.
While blood transfusion problems due to Langereis and Junior blood types are rare worldwide, several ethnic populations are at risk, Ballif notes. "More than 50,000 Japanese are thought to be Junior negative and may encounter blood transfusion problems or mother-fetus incompatibility," he writes.

Why Do Some People Learn Faster?
Why Do Some People Learn Faster? | Wired Science | Wired.com:
The physicist Niels Bohr once defined an expert as “a person who has made all the mistakes that can be made in a very narrow field.” Bohr’s quip summarizes one of the essential lessons of learning, which is that people learn how to get it right by getting it wrong again and again. Education isn’t magic. Education is the wisdom wrung from failure.
A new study, forthcoming in Psychological Science, and led by Jason Moser at Michigan State University, expands on this important concept. The question at the heart of the paper is simple: Why are some people so much more effective at learning from their mistakes? After all, everybody screws up. The important part is what happens next. Do we ignore the mistake, brushing it aside for the sake of our self-confidence? Or do we investigate the error, seeking to learn from the snafu?

Why Einstein's special theory of relativity is probably still correct - CSMonitor.com:
The world of science was upended last year when an experiment appeared to show one of Einstein's fundamental theories was wrong - but now the lab behind it says the result could have been caused by a loose cable.
Physicists at the CERN research institute near Geneva appeared to contradict Albert Einstein's 1905 Special Theory of Relativity last year when they reported that sub-atomic particles called neutrinos could travel fractions of a second faster than light.
Einstein's Special Theory of Relativity, which underpins the current view of how the universe works, says that nothing can travel faster than light, and doing so would be like traveling back in time.

Our Milky Way galaxy may be teeming with rogue planets that ramble through space instead of being locked in orbit around a star, a new study suggests.
These "nomad planets" could be surprisingly common in our bustling galaxy, according to researchers at the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC), a joint institute of Stanford University and the SLAC National Accelerator Laboratory. The study predicts that there may be 100,000 times more of these wandering, homeless planets than stars in the Milky Way.
If this is the case, these intriguing cosmic bodies would belong to a whole new class of alien worlds, shaking up existing theories of planet formation. These free-flying planets may also raise new and tantalizing questions in the search for life beyond Earth.

Abstinence-Only Sex Education Bill In Utah Prohibits Teaching Contraception
Abstinence-Only Sex Education Bill In Utah Prohibits Teaching Contraception:
'via Blog this'
A bill requiring sex education classes to teach an abstinence-only curriculum moved closer to becoming a law in Utah Wednesday.
The state House passed HB 363 in a 45-28 vote following extensive debate. The bill -- which now goes on to the state Senate -- would lift the current requirement that all public schools must teach sex ed in grades 8 through 12. If the bill passes, districts would decide whether to offer sex ed classes that teach an abstinence-only curriculum, or not offer the course at all. Republican state Rep. Bill Wright sponsored the proposal.
"We've been culturally watered down to think we have to teach about sex, about having sex and how to get away with it, which is intellectually dishonest," Wright said, according to The Salt Lake Tribune. "Why don't we just be honest with them upfront that sex outside marriage is devastating?"

Subatomic particles clocked at speeds exceeding the speed of light may have been going even faster than they appeared, physicists say.
A problem with some of the equipment used in the original experiment may have led to an overestimate of the time it took the particles, known as neutrinos, to make their 730-kilometre journey, reported CERN, the European Organization for Nuclear Research in a statement Thursday.
As a result, their speed may have been underestimated.
The problem was one of two equipment issues discovered by OPERA, the international physics collaboration that ran the experiment, CERN said.

Every sixty million years, the biodiversity of our planet's oceans mysteriously crashes. This strange boom and bust cycle goes back 500 million years, and we now might know why: rising continents make the oceans too shallow for species to survive.
The key to this mystery, according to new research led by University of Kansas physicist Adrian Melott, is the isotope strontium-87. This is one of four stable isotopes of the element strontium, although its less common (7.0%) than strontium-86 (9.86%) and much, much less abundant than strontium-88 (82.58%). The researchers, which also included paleontologist Richard Bambach and earth scientists Kenni D. Petersen and John M. McArthur, found that the concentration of Sr-87 relative to Sr-86 in marine fossils seems to increase every 60 million years, in lockstep with the periodic wave of extinction.

Would We Have Drugged Up Einstein? How Anti-Authoritarianism Is Deemed a Mental Health Problem | Personal Health | AlterNet:

In my career as a psychologist, I have talked with hundreds of people previously diagnosed by other professionals with oppositional defiant disorder, attention deficit hyperactive disorder, anxiety disorder and other psychiatric illnesses, and I am struck by 1) how many of those diagnosed are essentially anti-authoritarians; and 2) how those professionals who have diagnosed them are not.
Anti-authoritarians question whether an authority is a legitimate one before taking that authority seriously. Evaluating the legitimacy of authorities includes assessing whether or not authorities actually know what they are talking about, are honest, and care about those people who are respecting their authority. And when anti-authoritarians assess an authority to be illegitimate, they challenge and resist that authority—sometimes aggressively and sometimes passive-aggressively, sometimes wisely and sometimes not.

Error Undoes Faster-Than-Light Neutrino Results
BREAKING NEWS: Error Undoes Faster-Than-Light Neutrino Results - ScienceInsider:
'via Blog this'
It appears that the faster-than-light neutrino results, announced last September by the OPERA collaboration in Italy, was due to a mistake after all. A bad connection between a GPS unit and a computer may be to blame.
Physicists had detected neutrinos travelling from the CERN laboratory in Geneva to the Gran Sasso laboratory near L'Aquila that appeared to make the trip in about 60 nanoseconds less than light speed. Many other physicists suspected that the result was due to some kind of error, given that it seems at odds with Einstein's special theory of relativity, which says nothing can travel faster than the speed of light. That theory has been vindicated by many experiments over the decades.
According to sources familiar with the experiment, the 60 nanoseconds discrepancy appears to come from a bad connection between a fiber optic cable that connects to the GPS receiver used to correct the timing of the neutrinos' flight and an electronic card in a computer. After tightening the connection and then measuring the time it takes data to travel the length of the fiber, researchers found that the data arrive 60 nanoseconds earlier than assumed. Since this time is subtracted from the overall time of flight, it appears to explain the early arrival of the neutrinos. New data, however, will be needed to confirm this hypothesis.

Aging of Eyes Is Blamed in Circadian Rhythm Disturbances
Aging of Eyes Is Blamed in Circadian Rhythm Disturbances - NYTimes.com:

For decades, scientists have looked for explanations as to why certain conditions occur with age, among them memory loss, slower reaction time, insomnia and even depression. They have scrupulously investigated such suspects as high cholesterol, obesity, heart disease and an inactive lifestyle.
Now a fascinating body of research supports a largely unrecognized culprit: the aging of the eye.
The gradual yellowing of the lens and the narrowing of the pupil that occur with age disturb the body’s circadian rhythm, contributing to a range of health problems, these studies suggest. As the eyes age, less and less sunlight gets through the lens to reach key cells in the retina that regulate the body’s circadian rhythm, its internal clock.

The myth of the eight-hour sleep

We often worry about people who lie awake in the middle of the night - but it could be good for you. Scientists have been saying for 20 years that the eight-hour sleep may be unnatural, and historians increasingly are backing them up.
In the early 1990s, psychiatrist Thomas Wehr conducted an experiment in which a group of people were plunged into darkness for 14 hours every day for a month.
It took some time for their sleep to regulate but by the fourth week the subjects settled into a very distinct sleeping pattern. They slept first for four hours, then woke for one or two hours before falling into a second four-hour sleep.

Women may drool over George Clooney and Brad Pitt, but their lust may be more for these macho guys' immune systems than their pretty faces and chiseled abs, new research suggests.
Men with high levels of the sex hormone testosterone are seen as more hunky — and these same men have stronger immune responses, researchers report Tuesday (Feb. 21) in the journal Nature Communications. The findings suggest that women may be attracted to manly facial types because the macho look signals good health.
Researchers led by Fhionna Moore of Abertay University in the United Kingdom recruited 74 Latvian men in their early 20s to give blood samples right before and one month after their first dose of the Hepatitis B vaccine. The vaccine triggers the immune system to create antibodies against the virus. The researchers measured these levels of antibodies as well as testosterone levels and levels of the stress hormone cortisol.

A time crystal would be a physical object whose constituent parts move in a repeating pattern.

A leaky gut may be the root of some cancers forming in the rest of the body, a new study published online Feb. 21 in PLoS ONE by Thomas Jefferson University researchers suggests.
It appears that the hormone receptor guanylyl cyclase C (GC-C) -- a previously identified tumor suppressor that exists in the intestinal tract -- plays a key role in strengthening the body's intestinal barrier, which helps separate the gut world from the rest of the body, and possibly keeps cancer at bay. Without the receptor, that barrier weakens.

Recently while visiting the National Museum of Natural History in Washington, D.C., I found myself pondering the noggins of some very, very, old apes.
Along one wall of the Hall of Human Origins — an exhibit on human evolution that opened in 2010 — were 76 fossil skulls from 15 species of early humans. Looking at these skulls, one thing was clear: millions of years of evolution have given us much bigger brains.

The moon's crust was apparently active far more recently than previously believed, scientists say.
Although the Earth's crust is still shifting, driven by the churning semimolten rock underneath it, researchers had thought the moon had cooled off much too long ago to still have any such tectonic activity. For instance, the youngest known tectonic features on the lunar landscape until now -- small cliffs in the lunar highlands resulting from wrinkling of the surface as the moon's interior cooled and shrunk — are thought to be less than 1 billion years old, although by how much is uncertain.

Obesity rates rise, threaten health in OECD nations
Obesity rates rise, threaten health in OECD nations | Reuters:

More people in developed countries are overweight or obese than ever before, dooming them to years of ill health, pushing up healthcare costs and piling more pressure on health systems, a report by the OECD found on Tuesday.
The Paris-based Organisation for Economic Co-operation and Development found obesity rates vary widely from a low of 4 percent in Japan and Korea to 30 percent or more in the United States and Mexico.
But in more than half of the 34 OECD countries, at least one in two people is now overweight or obese, and rates are projected to rise further. In some countries, two out of three people will be obese within 10 years, the report said.

For the first time ever, scientists can control human brain cells using quantum dots
For the first time ever, scientists can control human brain cells using quantum dots:
'via Blog this'
What if you could treat conditions ranging from Alzheimer's to blindness, all with a flash of light? Researchers think it's possible — and they plan on using tiny particles called quantum dots to do it.
Brain stimulation can be incredibly tricky. Performing it from outside the head is effective, but doesn't give you very much specificity when it comes to turning on a specific brain region; sticking electrodes on the brain itself offers you precision, but it's also incredibly invasive.
Recently, researchers have sought out solutions to these problems with methods that rely on light, in hopes that they can be used to stimulate brain activity with a high level of precision without having to crack your skull open. Right now, the buzz-word in light-mediated brain stimulation is optogenetics, which looks incredibly promising, but relies on genetic modifications that are still considered too risky to test in humans.

Some bacteria have the capacity to stabilise uranium contaminated sites, and if they are used they could reduce the chances of these sites contaminating major waterways and ecosystems, U.S. scientists have said.
Of the millions of tonnes of bacteria living within the Earth's subsurface, some are able to transform the oxidative state of uranium, which defines how the element will interact with oxygen to form various molecules. They change it from the radioactive, toxic and water soluble uranium (VI) to the less soluble, stationary and therefore less harmful uranium (IV) as part of their normal growth.

Talk about seeing the light. Israeli scientists have developed a "sensory substitution device" (SSD) that they say lets congenitally blind people "see" for the first time ever.
The device is reminiscent of the electronic visor worn by Geordi La Forge, the blind engineer in the TV series "Star Trek: The Next Generation." It features a tiny computerized video camera that transforms light into so-called "soundscapes"--specific tones that the wearer interprets using his/her sense of hearing.
Using the SSD isn't actually seeing. But after a brief training session, wearers are able to identify everyday objects, locate people and their postures, and even read, according to a written statement released by Hebrew University of Jerusalem, where the technology was developed.

Hospitals might thwart the spread of dangerous infections by taking a tip from Florence Nightingale and throwing open their windows. But while the Victorian nurse championed fresh air and cleanliness as a defence against infections, the incoming air might help control nasty pathogens by letting more microbes inside.
Jack Gilbert, a microbiologist at the US government's Argonne National Laboratory in Illinois, offers the unconventional view that unwanted microbes might gain a foothold in hospitals because they had too little competition from other organisms.
The idea mirrors that seen in the gut, where antibiotics can kill off the balanced and healthy community of bacteria, only to make way for hardier bugs that cause illness.

Meat products grown in labs, or in vitro meat, has taken a considerable step closer to becoming reality this week, after the University of Maastricht’s Dr. Mark Post revealed pictures of a 2cm long piece of muscle that will eventually become edible meat. He announced his experiment in November last year, although the project has been running for six years.
Engineered from bovine stem cells, the initially white muscle is fed with a nutrient rich concoction, then exercised to help it grow and keep it lean, before being mixed with “blood and artificially grown fat” and arranged in layers to form a steak.
Unsurprisingly, given the amount of care and attention this little muscle needs, it’s a pricey experiment, with the final cost nudging $318,000 or £200,000. That’s an expensive burger.

But a study says inhaling that scent could actually fill your body with toxic fumes.
Researchers from the Ecology Center in Ann Arbor, Mich., tested dashboards, steering wheels, armrests and seats of more than 200 new cars – and found more than 275 chemicals.
The center’s research found these chemicals included brominated flame retardants, which have been linked to thyroid cancer, learning and memory impairment and decreased fertility.
Another chemical found in new cars? Polyvinal chloride, a chemical linked to problems with the liver, kidney and fertility.

Hands are keys to the past, even if there isn't much past to tell. A glance at a boy's digit ratio — the relative length of index to ring finger —shows if he was exposed to high testosterone levels before birth. These testosterone levels even lead to "manlier" faces, even before the boy hits puberty, the research suggests.
In the uterus, before a baby is born, testosterone seems to have what the researchers call an "organizing effect" on the face — it helps controls how the face and other parts of the body (including the sex organs and yes, the fingers) develop. This means that researchers can use digit ratio as a measurement of testosterone exposure before birth, which comes from both the mother and the developing baby. A low ratio, where the index finger is shorter than the ring finger, indicates high testosterone levels, and the opposite for a high ratio.

Such a “time crystal” would be the temporal equivalent of an everyday crystal, in which atoms occupy positions that repeat periodically in space.

It may be time to start paying more attention to those local air pollution alerts.
That is the message of three new studies this week that found, collectively, that people exposed to higher levels of air pollution have a greater risk of stroke, heart attacks and cognitive deterioration.
The impact of pollution on the heart and brain was seen over both the short and the long term. One nationwide study that followed nearly 20,000 women over a decade found that breathing in levels of polluted air like those commonly found in most parts of the country greatly accelerates declines in measures of memory and attention span. Another study in Boston found that on days when concentrations of traffic pollutants went up, so did the risk of stroke. The odds climbed by more than 30 percent even on days classified by the federal air quality index as “moderate” pollution days, which is intended to correspond to a minimal danger to health.

It has been known for some years that the problem with microwaved anything is not the radiation people used to worry about, it’s how it corrupts the DNA in the food so the body can not recognize it.
Microwaves don’t work different ways on different substances. Whatever you put into the microwave suffers the same destructive process. Microwaves agitate the molecules to move faster and faster. This movement causes friction which denatures the original make-up of the substance. It results in destroyed vitamins, minerals, proteins and generates the new stuff called radiolytic compounds, things that are not found in nature.

It was the holy grail of investors. The Black-Scholes equation, brainchild of economists Fischer Black and Myron Scholes, provided a rational way to price a financial contract when it still had time to run. It was like buying or selling a bet on a horse, halfway through the race. It opened up a new world of ever more complex investments, blossoming into a gigantic global industry. But when the sub-prime mortgage market turned sour, the darling of the financial markets became the Black Hole equation, sucking money out of the universe in an unending stream.

If you're going to be on either end of a kiss this Valentine's Day, you might want to consider smooching bare-lipped. Most lipstick contains lead.
Lead has been banned in paint since 1978 because of its toxicity at low levels, but it still shows up in small amounts in some of the best-selling lipstick brands.
The Campaign for Safe Cosmetics, which did an analysis of a study of lead in lipstick conducted by the U.S. Food and Drug Administration, wants consumers to know that most of the 400 different lipsticks tested were positive for the substance.

Equations reach far beyond technology too. Without them, we would have no understanding of the physics that governs the tides, waves breaking on the beach, the ever-changing weather, the movements of the planets, the nuclear furnaces of the stars, the spirals of galaxies - the vastness of the universe and our place within it.
There are thousands of important equations. The seven I focus on here - the wave equation, Maxwell's four equations, the Fourier transform and Schrödinger's equation - illustrate how empirical observations have led to equations that we use both in science and in everyday life.

Earth is getting 50,000 tonnes lighter every year, even while 40,000 tonnes of space dust fall on our planet's surface during the same period. So, why are we losing so much weight? You will be surprised.
At least, I never considered this and I was surprised to hear the reasoning in More or Less, a BBC Radio 4 program about statistics and numbers. According to Dr Chris Smith and Cambridge University physicist Dave Ansel's calculations, despite those 40,000 tonnes of space dust that become part of our planet every year, Earth loses 50,000 tonnes of mass. Is it because we keep launching rockets? No. These are their back-of-the-napkin calculations:

In the effort to convert sunlight into electricity, photovoltaic solar cells that use conductive organic polymers for light absorption and conversion have shown great potential. Organic polymers can be produced in high volumes at low cost, resulting in photovoltaic devices that are cheap, lightweight and flexible.
In the last few years, much work has been done to improve the efficiency with which these devices convert sunlight into power, including the development of new materials, device structures and processing techniques.

NO ONE WOULD accuse Jaroslav Flegr of being a conformist. A self-described “sloppy dresser,” the 63-year-old Czech scientist has the contemplative air of someone habitually lost in thought, and his still-youthful, square-jawed face is framed by frizzy red hair that encircles his head like a ring of fire.
Certainly Flegr’s thinking is jarringly unconventional. Starting in the early 1990s, he began to suspect that a single-celled parasite in the protozoan family was subtly manipulating his personality, causing him to behave in strange, often self-destructive ways. And if it was messing with his mind, he reasoned, it was probably doing the same to others.
The parasite, which is excreted by cats in their feces, is called Toxoplasma gondii (T. gondii or Toxo for short) and is the microbe that causes toxoplasmosis—the reason pregnant women are told to avoid cats’ litter boxes. Since the 1920s, doctors have recognized that a woman who becomes infected during pregnancy can transmit the disease to the fetus, in some cases resulting in severe brain damage or death. T. gondii is also a major threat to people with weakened immunity: in the early days of the AIDS epidemic, before good antiretroviral drugs were developed, it was to blame for the dementia that afflicted many patients at the disease’s end stage. Healthy children and adults, however, usually experience nothing worse than brief flu-like symptoms before quickly fighting off the protozoan, which thereafter lies dormant inside brain cells—or at least that’s the standard medical wisdom.

Does the language you speak really affect how you see the future?
Does the language you speak really affect how you see the future? | Digg Science:

The way people discuss the future varies from language to language. Some have a well-defined future tense, while others distinguish much between present and future. But does this point of grammar actually affect how we see the world?
As you may have seen in some recent reports elsewhere in the blogosphere, that question forms the basis for a new paper by Yale researcher Keith Chen. Chen - who, it should be pointed out, is an economist, not a linguist - is currently working on a paper in which he examines the effect of the future tense in different cultures' future-oriented behavior.
The idea is that some languages have very clear grammar governing the future tense - like in English, how we can distinguish between "I am doing something" and "I will do something" - whereas other languages don't. His hypothesis is that the former, the so-called strong future time references (FTR) languages, are more likely to make poor decisions in terms of planning for the future, which means higher rates of obesity, debt, smoking, drinking, and so forth.

Do mysterious laws link tennis rankings and earthquakes?
BBC News - Do mysterious laws link tennis rankings and earthquakes?:
'via Blog this'
Recent studies suggest maths laws may govern everything from the timing of earthquakes to tennis player rankings. But are these rules just a mirage?
In the 1930s, linguist George Kingsley Zipf spotted an unusual trend in languages.
In a given work of literature, the second-most commonly used word occurs half as often as the most-used. The third-most used word occurs one-third as often as the first, and so on.
He had discovered what has become the most widely known "power law".
It was a striking finding - that something as fluid and untamed as language can appear to be so incredibly ordered.
Power laws show up frequently in physics, where mathematical order is no surprise.

Health experts in Germany are baffled by a small village where cancer has hit almost every household.
Wewelsfleth, which has a population of 1,500, has been labelled the ‘village of the damned’ as new cancer cases are 50 per cent above average.
Researchers from the University of Lubeck who investigated the phenomenon, which includes breast, lung, oesophageal, womb and stomach cancers, could find no defining cause – although residents are blaming three nearby nuclear power plants and a shipyard where vessels used to be sprayed with highly toxic paint.

Genetically modified mosquitoes may soon be released in Florida
Genetically modified mosquitoes may soon be released in Florida:
'via Blog this'
In an effort to help eradicate dengue fever and the mosquitos that spread it, the Florida Keys Mosquito Control District (FKMCD) is seeking federal and state approval to release hundreds of thousands of genetically-modified (GM) mosquitos designed to kill off the natural Aedes aegypti variety of the fly throughout Key West, Florida.
The agency, which already routinely performs aerial sprayings of the area with anti-mosquito chemicals, believes it will save money in the long run by releasing the GM mosquitos. Rather than spend $400,000 or more a year to conduct the aerial sprayings, FKMCD says it would instead only have to spend $200,000 to $300,000 a year on the GM mosquitos.
Created by U.K.-based insect eradication company Oxitec, the GM mosquitos have been created with an added gene that, unless they are given the antibiotic tetracycline, will automatically kill them. When they mate with wild mosquitos, these GM mosquitos also pass on this gene to the offspring, which is intended to gradually decrease the population of wild mosquitos over time.

Have Bees Become Canaries In the Coal Mine? Why Massive Bee Dieoffs May Be a Warning About Our Own Health

It's often said that we have bees to thank for one out of every three bites we take of food. In addition to producing honey, honeybees literally criss-cross the United States, pollinating almonds, oranges, melons, blueberries, pumpkins, apples, and more. And while carrots are a biennial root crop that are harvested long before they flower, all carrots are planted from seed, and honeybees pollinate the carrot flowers that produce the seeds. Other species of bees, both social and solitary bees, pollinate other crops. And the populations of all these species of bees are in decline.
The decline of bees has been in the headlines for several years, and theories to explain their deaths abound. But perhaps there is not just one single cause. University of California San Diego professor of biology James Nieh studies foraging, communication and health of bees. "I would say it's a combination of four factors; pesticides, disease, parasites, and human mismanagement," says Nieh. Bees might be weakened by having a very low level of exposure to insecticides or fungicides, making them more susceptible if they are attacked by viruses or parasites. "It's kind of like taking a patient who is not doing so well -- very weak, poor diet, exposing them to pathogens, and then throwing more things at them. It's not surprising that honeybees are not very healthy."

In frightening situations, people tend to freeze, but not recent moms, who charge ahead. Now a new study shows how the brain speedily delivers the hormone oxytocin — which new mothers have in elevated levels, starting with childbirth — to where it's needed, freeing them to protect their young.
The study, done in rats, revealed that oxytocin rushes to the brain region governing fear, called the amygdala, courtesy of special cells that act like a neurological expressway.
Further, when the researchers provoked these cells into sending oxytocin to the amygdala, it diminished the rats' fearful responses to being startled.

Fracture Putty can heal a broken bone in days
Fracture Putty can heal a broken bone in days | Geek.com:
'via Blog this'
Broken bones can mean weeks of having to wear a cast and the muscle atrophy that comes with that. More severe breaks can take months to mend, result in restricted movement, or in the worst cases the possible loss of a limb. There’s also the chance of re-fracture due to the amount of time some breaks take to heal if a patient isn’t extremely careful.
Speeding up the time it takes to heal a broken bone is highly desirable, and a solution may be on the horizon. Research being carried out at the University of Georgia Regenerative Bioscience Center has helped create a new gel being referred to as Fracture Putty. It’s major benefit to those suffering broken bones is its ability to heal them in just a few days, or in the case of severe breaks, cut the healing time to weeks instead of months.
Fracture Putty has yet to be tested on humans, but it has already been proven to work in animals. The putty takes the form of a gel that gets injected into the broken bones. It then goes to work rapidly generating bone much faster than a body can achieve on its own.

Authoritarian parents whose child-rearing style can be summed up as "it's my way or the highway" are more likely to raise disrespectful, delinquent children who do not see them as legitimate authority figures than authoritative parents who listen to their children and gain their respect and trust, according to new research from the University of New Hampshire.
"When children consider their parents to be legitimate authority figures, they trust the parent and feel they have an obligation to do what their parents tell them to do. This is an important attribute for any authority figure to possess, as the parent does not have to rely on a system of rewards and punishments to control behavior, and the child is more likely to follow the rules when the parent is not physically present," said Rick Trinkner, a doctoral candidate at UNH and the lead researcher.
