Wood Nanobattery Could Be Green Option For Large-Scale Energy Storage 120

Posted by samzenpus
from the tree-power dept.
cylonlover writes "Li-ion batteries may be ok for your smartphone, but when it comes to large-scale energy storage, the priorities suddenly shift from compactness and cycling performance (at which Li-ion batteries excel) to low cost and environmental feasibility (in which Li-ion batteries still have much room for improvement). A new 'wood battery' could allow the emerging sodium-ion battery technology to fit the bill as a long-lasting, efficient and environmentally friendly battery for large-scale energy storage."

jpyeck writes "Lake Vostok, Antarctica's biggest and deepest subsurface lake, might contain thousands of different kinds of tiny organisms — and perhaps bigger fish as well, researchers report. The lake, buried under more than 2 miles (3.7 kilometers) of Antarctic ice, has been seen as an earthly analog for ice-covered seas on such worlds as Europa and Enceladus. It's thought to have been cut off from the outside world for as long as 15 million years. But the latest results, reported in the open-access journal PLOS ONE, suggest that the lake isn't as sterile or otherworldly as some scientists might have thought. More than 3,500 different DNA sequences were identified in samples extracted from layers of ice that have built up just above the surface of the lake."

From the article: 'When a smell source is placed under the device's glass cone, a pump extracts the smell via a plastic tube. After being drawn to Madeleine's main unit, the smell goes through a resin trap which absorbs the particles so molecular information can be recorded. That data is expressed in a graph-like formula, which essentially contains a fingerprint of the smell. In a special lab, that formula can then be inscribed on a bronze disk to artificially reproduce the smell. The smell can also be recreated in small vials.'"

'Benyus, who wrote Biomimicry: Innovation Inspired by Nature and co-founded the institute Biomimicry 3.8, would like to see a transition in manufacturing—from big, smoke-belching factories to small, clean desktop printers. The key to making it truly sustainable, she said, lies in mimicking how a natural ecosystem functions. "Nature uses life-friendly chemistry, which is nontoxic and water-based, and which does not require high heat," said Benyus. In contrast, most of the products people use today have been forged in industrial-size furnaces, with a plethora of toxic solvents. A potato chip bag may seem like a simple item, but it is actually made up of several thin layers of different materials, one to make it strong, one to make it airtight, and so on.'"

Patching Software on Another Planet 96

from the no-do-overs dept.
An anonymous reader writes "Sixteen years ago, the Mars Pathfinder lander touched down on Mars and began collecting about the atmosphere and geology of the Red Planet. Its original mission was planned to last somewhere between a week and a month, but it only took a few days for software problems to crop up. The engineers responsible for the system were forced to diagnose the problem and issue a patch for a device that was millions of miles away. From the article: 'The Pathfinder's applications were scheduled by the VxWorks RTOS. Since VxWorks provides pre-emptive priority scheduling of threads, tasks were executed as threads with priorities determined by their relative urgency. The meteorological data gathering task ran as an infrequent, low priority thread, and used the information bus synchronized with mutual exclusion locks (mutexes). Other higher priority threads took precedence when necessary, including a very high priority bus management task, which also accessed the bus with mutexes. Unfortunately in this case, a long-running communications task, having higher priority than the meteorological task, but lower than the bus management task, prevented it from running. Soon, a watchdog timer noticed that the bus management task had not been executed for some time, concluded that something had gone wrong, and ordered a total system reset.'"

The lasers pulse every 760 nanoseconds to induce red blood cells to emit sound waves with frequencies of more than 100MHz, one of the highest frequencies ever achieved. Testing the laser on blood samples collected from a group of human volunteers, researchers showed that the high-frequency sound waves emitted by red blood cells in the blood samples revealed the tiniest details about the cells' shapes. Because diseases like malaria can alter the shape of the body's cells, the device may provide a way to accurately diagnose various blood disorders before it's too late."

"The Keys and three South Florida counties agreed in 2010 to collaborate on a regional plan to adapt to climate change. The first action plan developed under that agreement was published in October and calls for revamped planning policies, more public transportation options, stopping seawater from flowing into freshwater supplies and managing the region's unique ecosystems so that they can adapt, too." The Keys are one of many places beginning to seriously evaluate their options for dealing with flooding after witnessing the damage caused by Hurricane Sandy.

Styx is the name of the river that separated the underworld from the real world. The names, picked in a popular contest, were actually the second and third choices. The first choice was Vulcan, which was officially touted because it was the name of a Roman god who was a relative of Pluto's and was associated with fire and smoke. The real reason that Vulcan shot up to the top of the list was that was a choice by Star Trek fans in a campaign instigated by actor William Shatner, who played Captain James Kirk in the original series."

The one problem with these transplants was that scientists were unable to connect the animals' spinal cords to their donor bodies, leaving them paralyzed below the point of transplant. But, says Canavero, recent advances in re-connecting spinal cords that are surgically severed mean that it should be technically feasible to do it in humans. (This is not the same as restoring nervous system function to quadriplegics or other victims of traumatic spinal cord injury.)"

Cosmic 'Booze' Created In Quantum Brewery 52

Posted by Unknown Lamer
from the galaxy-might-have-a-problem dept.
astroengine writes "The intense cold of interstellar space shouldn't be conducive to chemical reactions between methanol and hydroxyl radicals — two molecules that are known to exist in stellar nurseries and cold interstellar clouds — and yet the product of this reaction, methoxy radicals, are found in abundance throughout the universe. What is creating them? In a paper published in the journal Nature Chemistry (abstract), Dwayne Heard and colleagues from the University of Leeds think that interstellar alcohol is undergoing a destruction mechanism facilitated by a weird quantum effect known as tunneling. On encountering hydroxyl radicals, methanol molecules should be repelled by the electrostatic force. But at very low temperatures, when both chemicals are mixed in a cold gaseous state, quantum tunneling becomes extremely efficient at allowing chemical reactions to occur. The researchers write: 'at temperatures relevant to the interstellar medium, almost every collision between methanol and OH (hydroxyl) would result in a successful reaction to form CH3O (methoxy).' What's more, they find that the reaction rate is 50 times higher in the cold interstellar environment than it is at room temperature. 'If our results continue to show a similar increase in the reaction rate at very cold temperatures, then scientists have been severely underestimating the rates of formation and destruction of complex molecules, such as alcohols, in space,' said Heard."

CERN Testing Cloud For Crunching the Universe's Secrets 67

Posted by samzenpus

Nerval's Lobster writes "The European Organization for Nuclear Research (known as CERN) requires truly epic hardware and software in order to analyze some of the most epic questions about the nature of the universe. While much of that computing power stems from a network of data centers, CERN is considering a more aggressive move to the cloud for its data-crunching needs. To that end, CERN has partnered with Rackspace on a hybrid cloud built atop OpenStack, an open-source Infrastructure-as-a-Service (IaaS) platform originally developed by Rackspace as part of a joint effort with NASA. Tim Bell, leader of CERN's OIS Group within its IT department, suggested in an interview with Slashdot that CERN and Rackspace will initially focus on simulations—which he characterized as 'putting into place the theory and then working out what the collision will have to look like.' CERN's private cloud will run 15,000 hypervisors and 150,000 virtual machines by 2015—any public cloud will likely need to handle similarly massive loads with a minimum of latency. 'I would expect that there would be investigations into data analysis in the cloud in the future but there is no timeframe for it at the moment,' Bell wrote in a follow-up email. 'The experiences running between the two CERN data centers in Geneva and Budapest will already give us early indications of the challenges of the more data intensive work.' CERN's physicists write their own research and analytics software, using a combination of C++ and Python running atop Linux. 'Complex physics frameworks and the fundamental nature of the research makes it difficult to use off-the-shelf [software] packages,' Bell added."

Voyager 1 Finds Unexpected Wrinkles At the Edge Of the Solar System 164

Voyager 1 has been close to the boundary of the solar system for quite a while; we've mentioned that the edge is near a few times before, including an evidently premature report in 2010 that Voyager had reached a distance so far from the sun that it could no longer detect solar winds and another in 2011 that it had reached an "outer shell" of solar influence. It turns out that the boundaries of the solar system are fuzzier than once anticipated; the L.A. Times is reporting that "Toward the end of July 2012, Voyager 1's instruments reported that solar winds had suddenly dropped by half, while the strength of the magnetic field almost doubled, according to the studies. Those values then switched back and forth five times before they became fixed on Aug. 25. Since then, solar winds have all but disappeared, but the direction of the magnetic field has barely budged." Also at Wired, which notes "That's hard to explain because the galaxy's magnetic field is thought to be inclined 60 degrees from the sun's field. No one is entirely sure what's going on. ... [It's] almost as if Voyager thought it was going outside but instead found itself standing in the foyer of the sun's home with an open door that allows wind to blow in from the galaxy."

It will produce draft regulations later this year and the procedure could be offered within two years. Experts say three-person IVF could eliminate debilitating and potentially fatal mitochondrial diseases that are passed on from mother to child. Opponents say it is unethical and could set the UK on a 'slippery slope.' They also argue that affected couples could adopt or use egg donors instead. Mitochondria are the tiny, biological 'power stations' that give the body energy. They are passed from a mother, through the egg, to her child. Defective mitochondria affect one in every 6,500 babies. This can leave them starved of energy, resulting in muscle weakness, blindness, heart failure and death in the most extreme cases."

ananyo writes "Twisty beams of light could boost the traffic-carrying capacity of the Internet, effectively adding new levels to the information superhighway, suggests new research. In the last few years, different groups of researchers have tried to encode information in the shape of light beams to ease congestion, using a property of light called orbital angular momentum. Currently, a straight beam of light is used to transmit Internet signals, but certain filters can twist it so that it corkscrews around with varying degrees of curliness as it travels. Previous experiments using this effect have found that differently shaped light beams tend to jumble together after less than a meter. Now, a team of researchers from Boston University in Massachusetts and the University of Southern California in Los Angeles has found a way to keep the different light beam shapes separated for a record 1.1 kilometers. The most imminent use of the cables, the authors say, might be to install them to span the short distances between servers on giant 'server farms', used by large Web companies such as Facebook."

angry tapir writes "Researchers at Microsoft Research have produced a prototype software system that can be used on smartphones to infer a user's mood. The 'MoodScope' system produced by researchers uses smartphone usage patterns to determine whether someone is happy, calm, excited, bored or stressed and could potentially add a new dimension to to mobile apps (as well as, as the researchers note, open up a Pandora's Box of privacy issues). The researchers created a low-power background service for iPhones and Android handsets that (with training) can offer reasonable detection of mood and offers and API that app developers could hook into."

Scientists Work To Produce 'Star Trek' Deflector Shields 193

cold fjord writes "This might be useful. From CNN: 'Recent evidence from NASA's Curiosity rover mission to the Red Planet has revealed that astronauts on the round-trip would be exposed to high levels of radiation from cosmic rays and high-energy particles from the sun ... this would clearly be bad for your health — and it is proving difficult to find a solution. ... [S]hielding to completely block the radiation danger would have to be "meters thick" and too heavy to be used aboard a spacecraft. In contrast, ... science fiction fans have once again got used to the ease with which Captain Kirk gives the order for "shields up" and the crew of the Enterprise being protected instantly from the hostility of space. Perhaps though, a real Star Trek shield may no longer be science fiction — scientists at the UK's Rutherford Appleton Laboratory (RAL) certainly think so. They have been testing a lightweight system to protect astronauts and spacecraft components from harmful radiation and working with colleagues in America to design a concept spaceship called Discovery that could take astronauts to the Moon or Mars. "Star Trek has great ideas — they just don't have to build it," said Ruth Bamford, lead researcher for the deflector shield project at RAL. ... The RAL plan is to create an environment around the spacecraft that mimics the Earth's magnetic field and recreates the protection we enjoy on the ground — they call it a mini magnetosphere."

astroengine writes "This summer, the Japan Aerospace Exploration Agency (JAXA) plans to launch two amazingly cute yet advanced, white-helmeted robots into space. Then an astronaut aboard the International Space Station (ISS) will attempt to converse with one of them. Robot astronaut Kirobo and backup robot Mirata were created as part of the Kibo Robot Project, a collaboration among Robo Garage, Toyota, the University of Tokyo and the Japan Aerospace Exploration Agency JAXA. They aim to send the robots with the JAXA mission to the ISS on Aug. 4."

the_newsbeagle writes "Fast, cheap genetic sequencing machines have the potential to revolutionize science and medicine--but only if geneticists can figure out how to deal with the floods of data their machines are producing. That's where computer scientists can save the day. In this article from IEEE Spectrum, two computational biologists explain how they're borrowing big data solutions from companies like Google and Amazon to meet the challenge. An explanation of the scope of the problem, from the article: 'The roughly 2000 sequencing instruments in labs and hospitals around the world can collectively generate about 15 petabytes of compressed genetic data each year. To put this into perspective, if you were to write this data onto standard DVDs, the resulting stack would be more than 2 miles tall. And with sequencing capacity increasing at a rate of around three- to fivefold per year, next year the stack would be around 6 to 10 miles tall. At this rate, within the next five years the stack of DVDs could reach higher than the orbit of the International Space Station.'"

coondoggie writes "If you have ever visualized in your mind winning a race or overcoming a serious life hurdle then you understand at least some of the concept behind a new virtual video a technology that could help people with their social anxieties. Researchers say they have tested a system that lets people with all manner of social anxieties — from using public transportation and buying a drink at a bar to socializing at a party, shopping, or talking to a stranger — see themselves interacting in those situations via video capture."
