First time accepted submitter jds91md writes "Scientists at Stanford have developed a technique to see the structural detail of actual brains with resolution down to the cellular and axonal/dendritic level. The process called CLARITY allows a 'transparent' view of the brain without having to slice or section it in any way. From the article: 'Even more important, experts say, is that unlike earlier methods for making the tissue of brains and other organs transparent, the new process, called Clarity by its inventors, preserves the biochemistry of the brain so well that researchers can test it over and over again with chemicals that highlight specific structures within a brain and provide clues to its past activity. The researchers say this process may help uncover the physical underpinnings of devastating mental disorders like schizophrenia, autism, post-traumatic stress disorder and others.'"

At this week's American Chemical Society Nanoengineering expert Joseph Wang detailed his latest work in developing micromotors and microrockets that are so small that thousands would fit inside this 'o'. Such machines could someday perform microsurgery, clean clogged arteries or transport drugs to the right place in the body. But there are also possible uses in cleaning up oil spills, monitoring industrial processes and in national security."
astroengine writes "Saturn's rings rain charged water particles down onto the gas giant's atmosphere, causing measurable changes in the planet's ionosphere. This intriguing conclusion comes from astronomers using the W. M. Keck Observatory atop Mauna Kea in Hawaii that observed dark bands forming in Saturn's ionosphere. 'Saturn is the first planet to show significant interaction between its atmosphere and ring system,' said James O'Donoghue, postgraduate researcher at the University of Leicester and lead author of a paper to appear this week in the journal Nature. 'The main effect of ring rain is that it acts to 'quench' the ionosphere of Saturn, severely reducing the electron densities in regions in which it falls.'"
New kalalau_kane writes with this tidbit from Extreme Tech: "A group of European researchers has proposed the largest quantum network yet: Between Earth and the International Space Station. Such a network would see entangled photons transmitted over a distance of 250 miles — two or three times greater than previous quantum communication experiments. Not only will this be the first quantum experiment in space, but it will allow the scientists to see if entanglement really is instantaneous over long distances, and whether it's affected by gravity."

sciencehabit writes "Get used to a bumpy ride. The strength and frequency of atmospheric turbulence affecting transatlantic flights will increase by midcentury, a new study suggests. During winter months, 16 of the 21 often-used ways in which scientists measure turbulence suggest that the average intensity of the plane-rattling phenomenon will be between 10% and 40% stronger when CO2 concentrations are double their preindustrial value. Accordingly, the frequency of moderate-or-greater turbulence—intensities at which passengers will experience accelerations of 0.5 g or more, which are strong enough to toss items about the cabin—will rise by between 40% and 170%. As a result of pilots needing to dodge strong turbulence, flight paths will become longer, and fuel consumption and carbon dioxide emissions will increase—possibly leading to even more turbulence."

The New York Times just published an exposée of sorts on the topic. Its only an exposée of sorts because the scientific community knows about the problem. There are blogs set up to shame the fake journals into halting publishing. There are tutorials online for spotting a fake journal. There's even a list created and maintained by academic librarian Jeffrey Beall that keeps an eye on all the new fake journals coming out. When Beall started the list in 2010, it had only 20 entries. Now it has over 4,000. The journal Nature even published an entire issue on the problem a couple of weeks ago. So again, scientists know this is a problem. They just don't know how to stop it."
astroengine writes "Almost every month we see news dispatches from the Mars where the nuclear-powered rover Curiosity finds water-bearing minerals in rocks and other circumstantial clues that the Red Planet could have once supported life. But in terms of finding direct evidence of past or present Martians, the rover barely scratches the surface, says geochemist Jan Amend of the University of Southern California. Using Earth life as an example, some species of microbes live miles below the surface, without sunlight or oxygen, metabolizing chemicals that are the result of radioactive decay. Most intriguing of all is the microbe Desulforudis Audaxviator that dwells nearly two miles down, a life form that would feel right at home inside Mars' crust. 'This organism has had to figure out everything on its own,' says Amend, 'it splits water into hydrogen and oxygen for metabolism.' Amend hopes to drop probes deep underground in some of the world's most inhospitable locations over the next few years, creating a possible analog for future Mars subsurface studies."
waderoush writes "At a time of sequesters and shrinking R&D spending, critics are attacking President Obama's proposed Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) initiative, which would have a $100 million budget starting in 2014. But in fact, the project 'runs the risk of becoming a casualty of small-bore thinking in science business, and politics,' argues Xconomy national life sciences editor Luke Timmerman. The goal of the BRAIN initiative is to develop technologies for exploring the trillions of synapses between neurons in the human brain. If the $3 billion Human Genome Project and its even more productive sequel, the $300-million-per-year Advanced Sequencing Technologies program, are any guide, the initiative could lead to huge advances in our understanding of Alzheimer's disease, epilepsy, and consciousness itself. Only government can afford to think this big, argues Timmerman. 'Even though $100 million a year is small change by federal government standards,' Timmerman writes, 'it is enough to create a small market that gives for-profit companies assurance that if they build such tools, someone will buy them. We ought to be talking about how we can free up more money to achieve our neuroscience goals faster, rather than talking about whether we can afford this puny appropriation at all.'"

astroengine writes "NASA has selected a $200 million mission to carry out a full-sky survey for exoplanets orbiting nearby stars. The space observatory, called the Transiting Exoplanet Survey Satellite, is scheduled for a 2017 launch. Like the currently operational Kepler Space Telescope, TESS will be in the lookout for exoplanets that orbit in front of their host stars, resulting in a slight dip in starlight. This dip is known as a "transit" and Kepler has revolutionized our understanding about planets orbiting other stars in our galaxy by applying this effective technique. As of January 2013, Kepler has spotted 2,740 exoplanetary candidates. "TESS will carry out the first space-borne all-sky transit survey, covering 400 times as much sky as any previous mission," said TESS lead scientist George Ricker, of the Massachusetts Institute of Technology Kavli Institute for Astrophysics and Space Research. "It will identify thousands of new planets in the solar neighborhood, with a special focus on planets comparable in size to the Earth.""

ananyo writes "According to the accepted account, an astronaut falling into a black hole would be ripped apart, and his remnants crushed as they plunged into the black hole's infinitely dense core. Calculations by Joseph Polchinski, a string theorist at the Kavli Institute for Theoretical Physics in Santa Barbara, California, though, point to a different end: quantum effects turn the event horizon into a seething maelstrom of particles and anyone who fell in would hit a wall of fire and be burned to a crisp in an instant. There's one problem with the firewall theory. If Polchinski is right, then either general relativity or quantum mechanics is wrong and his work has triggered a mini-crisis in theoretical physics."

'We are hoping to give us a much more powerful source of energy in space that could eventually lead to making interplanetary travel commonplace.' 'The research team has developed a type of plasma that is encased in its own magnetic field. Nuclear fusion occurs when this plasma is compressed to high pressure with a magnetic field. The team has successfully tested this technique in the lab. Only a small amount of fusion is needed to power a rocket – a small grain of sand of this material has the same energy content as 1 gallon of rocket fuel.'"

The app, called Good Times, is the brainchild of Ruggero Scorcioni, CEO and founder of Brainyno, who presented the technology at the AT&T Innovation Showcase in New York, where some of the company's top research projects were highlighted. The app analyzes brainwaves as a phone call comes in, and depending on a person's mental state, reroutes a call. Information about brain waves is collected by a headset and sent to the smartphone via a Bluetooth connection, after which the app uses algorithms to analyze the status of a brain." Of course, the user has to be wearing a headset to detect the brainwaves. The software's creator hopes such detection can someday be integrated into devices like Google Glass.

astroengine writes "The Kepler space telescope's prime objective is to hunt for small worlds orbiting distant stars, but that doesn't mean it's not going to detect some extreme relativistic phenomena along the way. While monitoring a red dwarf star — designated KOI-256 — astronomers detected a dip in starlight in the Kepler data. But it wasn't caused by an exoplanet. After some careful detective work, the researchers found that the red dwarf was actually in orbit around a binary partner — a white dwarf. As the white dwarf passed in front of the red dwarf, the starlight was enhanced by microlensing — a phenomenon caused by an intense gravitational field focusing light from behind. This had the counter-intuitive result of causing the starlight to dim when the white dwarf passed behind the red dwarf and then brighten as the white dwarf passed in front. This is one of the first discoveries of a binary partner through microlensing. 'Only Kepler could detect this tiny, tiny effect,' said Doug Hudgins, Kepler program scientist at NASA Headquarters, Washington. 'But with this detection, we are witnessing Einstein's theory of general relativity at play in a far-flung star system.'"
An anonymous reader writes "The prelimbic region of the prefrontal cortex in the human brain is thought to play a key role in drug addiction, and researchers at the National Institute on Drug Abuse wanted to see if manipulating cells there had a positive or negative impact on that addiction. They got some rats addicted to cocaine but not before loading them up with light sensitive proteins called rhodopsins that were placed in their prefrontal cortex, attaching to the neurons there. By shining a tuned laser light on to the prefrontal cortex, it was possible to activate and deactivate the cells. By turning them on with the laser, the addictive behavior of the rats was removed. Turning them off, even in non-addicted rats, saw the addictive behavior return or introduced."

By doing a tally of electrons and positrons, physicists hope the AMS will help to answer one of the most enduring mysteries in science: Does dark matter exist? And today, it looks like the answer is a cautious, yet exciting, affirmative."

It was one done by the famous Chan Canasta -- and Randi claims that in the end he figured it out, anyway. So forget the $1 Million, relax, and enjoy James Randi. He's a great raconteur, so we can all be jealous of interviewer Rob Rozeboom (samzenpus) for having made this great video even as we enjoy watching it.
James Randi answered your questions. But that was text, and he's a performer ("The Amazing Randi"), so you need to hear the man talk to get his full flavor. He's a good talker, too. So Rob Rozeboom (samzenpus) got on Skype with The Amazing Randi to talk about his exploits, including his debunking of a whole bunch of (alleged) frauds, ranging from Uri Geller to Sylvia Browne. The resulting interview was so long and so strong that we cut it in half. Today you see Part One. Tomorrow you'll see Part Two. (The video's here now; sorry about the delay.)
astroengine writes "It may not be a lander or an orbiter, but its something. Europa, one of Jupiter's largest moons, has been the focus of much scrutiny over its potential life-bearing qualities. It has an icy crust over a liquid water ocean and now salts have been detected on its surface, suggesting a cycling of nutrients from the surface to the interior. This only amplifies the hypothesis that Europa not only could support basic life, it could support complex life. But how can we find out? The proposed Europa Clipper received interest at NASA HQ last year as it would optimize the science while keeping the mission budget under $2 billion. It would be a spacecraft that will be in orbit around Jupiter, but make multiple flybys of Europa to assess the moon for its habitable qualities. Now, in a bill signed by President Obama and approved by lawmakers, $75 million has been allocated (for the remainder of this fiscal year) for a 'Jupiter Europa mission.' Could it represent the seed money for the Europa Clipper? We'll have to wait and see."

ananyo writes "Nature has published an investigation into the real costs of publishing research after delving into the secretive, murky world of science publishing. Few publishers (open access or otherwise-including Nature Publishing Group) would reveal their profit margins, but they've pieced together a picture of how much it really costs to publish a paper by talking to analysts and insiders. Quoting from the piece: '"The costs of research publishing can be much lower than people think," agrees Peter Binfield, co-founder of one of the newest open-access journals, PeerJ, and formerly a publisher at PLoS. But publishers of subscription journals insist that such views are misguided — born of a failure to appreciate the value they add to the papers they publish, and to the research community as a whole. They say that their commercial operations are in fact quite efficient, so that if a switch to open-access publishing led scientists to drive down fees by choosing cheaper journals, it would undermine important values such as editorial quality.' There's also a comment piece by three open access advocates setting out what they think needs to happen next to push forward the movement as well as a piece arguing that 'Objections to the Creative Commons attribution license are straw men raised by parties who want open access to be as closed as possible.'"
