Toxic barbs on a cucumber’s skin, nanoscopic flakes of metal and a mouse’s technicolor eyeball (above) are just a few of 2011′s top science visualizations.A panel of judges picked the best of more than 200 entries from 33 countries for the 2011 International Science and Engineering Visualization Challenge.
“I think because information technology tools and visualization tools have advanced, people have found ever-increasingly clever ways to display difficult scientific concepts,” said competition judge Thomas Wagner, a cryosphere scientist at NASA, in an interview provided by the contest.Contest judges made their picks based on visual impact, originality and clarity.
The winners, which include “people’s choice” awards as well as honorable mentions, were published online Feb. 2 in the journal Science.The entries weren’t just limited to photographs.

Incredible Photographic Survey of Military Kits From 1066 to 2014 - My Modern Met. UK-based photographer Thom Atkinson's series Soldiers' Inventories is an incredibly extensive photographic survey of the military kits carried by British soldiers from 1066 to 2014.
With the goal of exploring what he describes as "the mythology surrounding Britain’s relationship with war," Atkinson enlisted the help of reenactment groups, collectors, historians, and serving soldiers in order to assemble the components of each inventory. With each kit marking a landmark battle in the last millennium, the series is an eye-opening look at what a soldier's material world is reduced to during times of war. Atkinson's project shows the remarkable similarities and differences between military kits separated by decades and even centuries. Swords became guns; notepads became iPads; 18th-century bowls became mess tins.
While tools have evolved considerably, the heart of the necessities—uniforms, weapons, equipment, and especially personal items—remain the same. Help make it happen for GravityLight, lighting for the developing countries. Zeolite thermal storage retains heat indefinitely, absorbs four times more heat than water. Hold onto your hat/life partner/gonads: Scientists in Germany have created small, zeolite pellets that can store up to four times more heat than water, loss-free for “lengthy periods of time.”
In theory, you can store heat in these pellets, and then extract exactly the same amount of heat after an indeterminate amount of time. Zeolites (literally “boil stones”) aren’t exactly new: The term was coined in 1756 by Axel Cronstedt, a Swedish mineralogist who noted that some minerals, upon being heated, release large amounts of steam from water that had been previously adsorbed. For the last 250 years, scientists have tried to shoehorn this process in a heat storage system — and now, the Fraunhofer Institute, working with industrial partners, has worked out how to do it. I will try to explain how this works, but the science is fairly complicated: When Fraunhofer’s zeolite comes into contact with water, a chemical reaction adsorbs the water and emits heat.
New 'soft' motor made from artificial muscles. Public release date: 15-Feb-2012 [ Print | E-mail Share ] [ Close Window ] Contact: Jennifer Lauren Leejlee@aip.org 301-209-3099American Institute of Physics "Perhaps the earliest public demonstration of an electric motor," writes a team of researchers from the University of Auckland in New Zealand, "involved the automatic rotation of a turkey on a spit over a fire" at a party put on by Benjamin Franklin in 1749. Franklin's electrostatic motor was self-commutating, meaning that it was able to provide a continuous torque while it turned without requiring external electronics to control its progress.
Using artificial muscles, hyper-elastic materials that expand when a charge is applied, the New Zealand team has made a prototype for a self-commutating artificial muscle motor that does not require external electronics or hard metal parts. What causes language switching in bilinguals? The proficiency that a bilingual person has of both languages, the context in which he speaks them or unconscious changes in their use are the factors that make people who speak Spanish and Catalan switch from one language to another.
The group of Cognition and Brain Plasticity at the Bellvitge Biomedical Research Institute (IDIBELL), led by Antoni Rodríguez-Fornells, has designed a questionnaire that allows understanding individual differences among bilinguals when they change the language (switching). The study was conducted on a sample of 566 college students Spanish-Catalan bilingual and has been published in the latest issue of the journal Frontiers in Psychology. This questionnaire has already begun to be used in bilingual individuals in Montreal, Canada, who speak English and French, in Finland (Finnish and Swedish), in France and also in India. Having made this clarification, the study identifies several factors that make individuals changing the language they use. 2012 Annual Question. The Epidemic of Obesity, Diabetes and "Metabolic Syndrome:" Cell Energy Adaptations in a Toxic World?
"Metabolic syndrome" (MetSyn) has been termed the "Epidemic of the 21st century. " MetSyn is an accretion of symptoms, including high body mass index (weight-for-height), high blood sugar, high blood pressure (BP), high blood triglycerides, high waist circumference (central/visceral fat deposition), and/or reduced HDL-cholesterol, the so-called "good" cholesterol. Epidemics of Obesity and diabetes are intertwined with, and accompany, the meteoric rise in MetSyn.
The prevalent view is that MetSyn is due to a glut of food calories ("energy") consumed, and a dearth of exercise energy expended, spurring weight gain—an "energy surfeit"—with the other features arising in consequence. Top 10 ways to save money through sharing. Sharing stuff and services conserves resources and builds our ties with our neighbors—but it also saves money, sometimes a lot of money.
The first step is to do an inventory and look at the ways you're already sharing; I bet you'll be surprised. Then ask yourself, what else can I share? Here are ten of our top suggestions, culled from a year's worth of content on Shareable.net—and we’d love to hear yours in a comment! 10. Printed Sensors Could Help Save You From Spoiled Food.

Magnetoastrocoolness: How Cosmic Magnetic Fields Shape Planetary Systems. AUSTIN, Texas—Astrophysicists have a funny attitude toward magnetic fields. You might say they feel both repelled and attracted. Gravitation is assumed to rule the cosmos, so models typically neglect magnetism, which for most researchers is just as well, because the theory of magnetism has a forbidding reputation.
The basic equations are simple enough, solving them less so. Book Review: Our Magnetic Earth, by Ronald Merrill. A magnetic sense is now well documented in dozens of animal species. It turns out that tracking the geomagnetic field—that same invisible thing that points compasses—is handy for life, in lots of situations. Using their internal compasses, naked mole rats in Africa navigate their pitch-black underground mazes. Lobsters off Bermuda find their way to regions of the seafloor where they congregate to spawn. Thrushes migrate south in the autumn and north in the spring. Alexander's Horned Sphere fractal changes how we define inside and outside. I think what they mean is that for a common sphere, everything is uniform enough to slip the band off again with no damage to the sphere or the band.
With a hrned sphere, because it branches off infintismally, any attempt to put a band around it will either damage the sphere, or damage the band becuae it gets snagged on a branch. Simple technique results in surprising repellency results.
