Hydrogel Process Creates Transparent Brain For Research 46

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.'"

Climate Change Will Boost Plane Turbulence, Suggests Study 184

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."

Teachers Know If You've Been E-Reading 348

RougeFemme writes with this story in the New York Times about one disconcerting aspect of the ongoing move to electronic textbooks: "Teachers at 9 colleges are testing technology from a Silicon Valley start-up that lets them know if you're skipping pages, highlighting text, taking notes — or, of course, not opening the book at all. '"It's Big Brother, sort of, but with a good intent," said Tracy Hurley, the dean of the school of business at Texas A&M.' 'Major publishers in higher education have already been collecting data from millions of students who use their digital materials. But CourseSmart goes further by individually packaging for each professor information on all the students in a class — a bold effort that is already beginning to affect how teachers present material and how students respond to it, even as critics question how well it measures learning.'"

HP Launches Moonshot 168

New submitter linatux writes "HP has announced their 'Moonshot 1500 server' — up to 1,800 servers per 47U rack are supported. The tech certainly seems to be an advance on what is currently available — will it be enough to revive HP's server fleet?" From Phoronix: "Moonshot began with Calxeda-based ARM SoCs, but in the end HP settled for Intel Atom processors. Released today were HP's Moonshot system based on the Intel Atom S1200. Hewlett-Packard claims that their Moonshot System uses 89% less energy, 80% less space, 77% less cost, and 97% less complexity than traditional servers."

AMI Firmware Source Code, Private Key Leaked 148

Trailrunner7 writes "Source code and a private signing key for firmware manufactured by a popular PC hardware maker American Megatrends Inc. (AMI) have been found on an open FTP server hosted in Taiwan. Researcher Brandan Wilson found the company's data hosted on an unnamed vendor's FTP server. Among the vendor's internal emails, system images, high-resolution PCB images and private Excel spreadsheets was the source code for different versions of AMI firmware, code that was current as of February 2012, along with the private signing key for the Ivy Bridge firmware architecture. AMI builds the AMIBIOS BIOS firmware based on the UEFI specification for PC and server motherboards built by AMI and other manufacturers. The company started out as a motherboard maker, and also built storage controllers and remote management cards found in many Dell and HP computers. 'The worst case is the creation of a persistent, Trojanized update that would allow remote access to the system at the lowest possible level,' researcher Adam Caudill said. 'Another possibility would be the creation of an update that would render the system unbootable, requiring replacement of the mainboard.'"

HP Chairman Raymond Lane Steps Down 89

First time accepted submitter gkndivebum writes "The latest casualty from the ill-fated acquisition of British company Autonomy by HP appears to be Raymond Lane, who was recently re-elected by only 58.8% of shareholders. Mr. Lane will remain on the board with shareholder Ralph Whitworth as interim chairman. It will be interesting to see where the 'evolution' of the board as articulated by Mr. Whitworth leads."

Dark Matter Found? $2 Billion Orbital Experiment Detects Hints 173

astroengine writes "A $2 billion particle detector attached to the International Space Station has detected the potential signature of dark matter annihilation in the Cosmos, scientists have announced today. The Alpha Magnetic Spectrometer (AMS) was attached to the space station in May 2011 by space shuttle Endeavour — the second-to last shuttle mission to the orbital outpost. Since then, the AMS has been detecting electrons and positrons (the electron's anti-particle) originating from deep space and assessing their energies. 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."

HP Not Giving Up On Autonomy 36

Nerval's Lobster writes "After defeating a shareholder insurrection that largely stemmed from how it handled the Autonomy acquisition, Hewlett-Packard is trying to resuscitate the fortunes of that troubled analytics-software unit. In an interview, Robert Youngjohns, General Manager of the Autonomy division for HP, conceded that the controversy surrounding the acquisition and its aftermath has proven a significant distraction for the company. ... HP's ambitious turnaround plan involves focusing Autonomy technology, which can help find the right data in huge datasets, on areas such as Web content management and information governance. But it's a big question whether HP can overcome all the negative publicity swirling around Autonomy, widely seen as a poor acquisition: Back in November 2012, HP accused Autonomy's management team of using 'accounting improprieties, misrepresentations and disclosure failures to inflate the underlying financial metrics of the company.' It alerted the SEC's Enforcement Division and the United Kingdom's Serious Fraud Office (Autonomy is based in the U.K.), and announced it would take an $8.8 billion write-down on Autonomy's value. That sort of thing could make Autonomy a tough sell to companies still trying to figure out if they even need so-called 'Big Data' tools."

Why You Should Worry About the Future of Chromebooks 216

dcblogs writes "PC manufacturers may try to corral Chromebook, much like Netbooks, by setting frustratingly low hardware expectations. The systems being released from HP, Acer, Lenovo and Samsung are being built around retro Celeron processors and mostly 2 GB of RAM. By doing so, they are targeting schools and semi-impulse buyers and may be discouraging corporate buyers from considering the system. Google's Pixel is the counter-force, but at a price of $1,299 for the Wi-Fi system, reviewers, while gushing about hardware, believe it's too much, too soon. The Chromebook is a threat to everything, especially PC makers, as its apps improve. Compare Tweetdeck's HTML5 version with its native app. Can you tell the difference? It might be a year or two before Adobe delivers Web-only versions of its products, but if it doesn't it will be surrendering larger portions of its mindshare to users of Pixlr, Pixel Mixer, PicMonkey and many other interesting and increasingly capable tools."

Why Bad Directors Aren't Thrown Out 205

An anonymous reader writes "For publicly-owned companies, the CEO gets most of the spotlight. If the company is successful and the stock goes up, the CEO gets the credit. If the company stumbles, the CEO gets the blame. But an article at the NY Times points how the board of directors for most companies seem to get a free pass, even when their decisions or their CEO selections consistently go wrong. 'Last year, there were elections for 17,081 director nominees at United States corporations, according to the service. Only 61 of those nominees, or 0.36 percent, failed to get majority support. More than 86 percent of directors received 90 percent or more of the votes. Of the 61 directors who failed to get majority approval, only six actually stepped down or were asked to resign. Fifty-one are still in place, as of the most recent proxy filings.' The article uses Hewlett-Packard as an example; the past several years have seen poor CEO choices, the abominable Autonomy acquisition, and billions in write-offs for other failed endeavors. Yet HP's directors were all re-elected."

Biological Computer Created at Stanford 89

sciencehabit writes "For the first time, synthetic biologists have created a genetic device that mimics one of the widgets on which all of modern electronics is based, the three-terminal transistor. Like standard electronic transistors, the new biological transistor is expected to work in many different biological circuit designs. This should make it easier for scientists to program cells to do everything from monitor pollutants and the progression of disease to turning on the output of medicines and biofuels."

Bees Communicate With Electric Fields 133

sciencehabit writes "The electric fields that build up on honey bees as they fly, flutter their wings, or rub body parts together may allow the insects to talk to each other, a new study suggests. Tests show that the electric fields, which can be quite strong, deflect the bees' antennae, which, in turn, provide signals to the brain through specialized organs at their bases. Antenna deflections induced by an electrically charged honey bee wing are about 10 times the size of those that would be caused by airflow from the wing fluttering at the same distance—a sign that electrical fields could be an important signal."

Washington's Exploding Manholes Explained? 112

sciencehabit writes "Researchers who mapped methane concentrations on the streets of the nation's capital found natural gas leaks everywhere, at concentrations of up to 50 times the normal background levels. The leaking gas wastes resources, enhances ozone production, and exacerbates global warming—not to mention powering the city's infamous exploding manholes. Most of the natural gas we burn for heat and on stovetops in the United States is methane, a simple carbon atom surrounded by four hydrogens. Carbon dioxide gets more press, but methane is the more powerful agent of global warming, 21 times more effective than carbon dioxide at trapping heat in the atmosphere. And methane levels are rising fast. Methane levels in the atmosphere were just 650 parts per billion a century ago, versus 1800 ppb today."

New Advance In 3D TV Technology 143

sciencehabit writes "If you've pondered whether to sink a cool couple of grand into a fancy new three-dimensional TV but didn't want to mess around with those dorky glasses, you may want to sit tight for a few more years. Researchers at Hewlett Packard Laboratories in Palo Alto, California, report that they've come up with a new 3D technology that not only doesn't require viewers to wear special glasses, but it also can be viewed from a wide variety of angles. The advance could propel the development of mobile 3D devices as well as TVs."

Roadkill Forcing Cliff Swallows To Evolve 387

sciencehabit writes "Cliff swallows that build nests that dangle precariously from highway overpasses have a lower chance of becoming roadkill than in years past thanks to a shorter wingspan that lets them dodge oncoming traffic. That's the conclusion of a new study based on 3 decades of data collected on one population of the birds. The results suggest that shorter wingspan has been selected for over this time period because of the evolutionary pressure put on the population by cars."

Earthquakes Deposit Gold In Fault Zones 55

sciencehabit writes "Gold deposits may be created in a flash—literally. Along fault zones deep within Earth's crust, small cavities filled with fluids rich in dissolved substances such as gold and silicate minerals can expand suddenly to as much as 130,000 times their former size during a major earthquake, a new analysis suggests. In such circumstances, pressure drops accordingly, driving a process the scientists call flash evaporation. And when the pressure in the cavity suddenly drops, so does the solubility of minerals in the water there. Along with substantial quantities of quartz, large earthquakes could deposit as much as 0.1 milligrams of gold along each square meter of a fault zone's surface in just a fraction of a second Typical rates of seismicity along a fault, such as the San Andreas fault zone shown in the main image, could generate a 100-metric-ton deposit of gold in less than 100,000 years."

Microbes Likely Abundant Hundreds of Meters Below Sea Floor 68

sciencehabit writes "Samples drilled from 3.5-million-year-old seafloor rocks have yielded the strongest evidence yet that a variety of microorganisms live deeply buried within the ocean's crust. These microbes make their living by consuming methane and sulfate compounds dissolved in the mineral-rich waters flowing through the immense networks of fractures in the crust. The new find confirms that the ancient lavas formed at midocean ridges and found throughout deep ocean basins are by volume the largest ecosystem on Earth, scientists say."

UK Serious Fraud Office Probes Autonomy With ... Autonomy! 34

judgecorp writes "The British Serious Fraud Office (SFO) is investigating whether British software firm Autonomy fiddled its accounts to inflate the price which HP paid for it to a whopping $10 billion. There's a problem though. Autonomy's Introspect software is used to trawl large data sets for information and is in use at the SFO for jobs such as this fraud investigation. It's not just ironic: the SFO says its £4.6 million contract with Autonomy could create a conflict of interest and it may have to pull out of the investigation."

Astronomers Probe Mysterious Gas In Titan's Atmosphere 104

sciencehabit writes "A fluorescent glow high in the atmosphere of Titan, Saturn's largest moon, signifies the presence of a gas that astronomers have yet to identify. The glow appears only on the daytime side of the moon at altitudes between 600 and 1250 kilometers, with the largest intensity occurring at an altitude of about 950 km. Detailed analyses reveal that the glow doesn't stem from a problem with the Saturn-orbiting Cassini craft, and it isn't associated with methane or any of the other hydrocarbons already identified as constituents of Titan's atmosphere."

Sheryl Sandberg and Technology's Female Leaders 181

AlistairCharlton writes "While the rest of the world continues to see men dominating, the technology industry seems set to change that. I investigate how Sheryl Sandberg, Marissa Mayer, Meg Whitman and Joanna Shields are paving the way for the rest of the business community. From the article: 'A glance at the male/female split of world leaders (178/17), Fortune 500 CEOs (96 percent/four percent) and FTSE 100 board seats (85 percent/15 percent) reveals there is a huge imbalance between the sexes, but in technology change is underway - and Sandberg is at the very forefront of it. Along with Meg Whitman, Marissa Mayer and Joanna Shields of HP, Yahoo and London's Tech City respectively, Sandberg represents a shift in what was not so long ago an all-male industry.'"
