New Device Hides, On Cue, from Infrared Cameras
Now you see it, now you don't. A new device invented at the Harvard School of Engineering and Applied Sciences (SEAS) can absorb 99.75% of infrared light that shines on it. When activated, it appears black to infrared cameras.

Flexible, Low-Voltage Circuits Made Using Nanocrystals
Electronic circuits are typically integrated in rigid silicon wafers, but flexibility opens up a wide range of applications. In a world where electronics are becoming more pervasive, flexibility is a highly desirable trait, but finding materials with the right mix of performance and manufacturing cost remains a challenge.

Use of Stem Cells in Personalized Medicine
Johns Hopkins researchers report concrete steps in the use of human stem cells to test how diseased cells respond to drugs. Their success highlights a pathway toward faster, cheaper drug development for some genetic illnesses, as well as the ability to pre-test a therapy's safety and effectiveness on cultured clones of a patient's own cells.

Using Biomarkers from Prehistoric Human Feces to Track Settlement and Agriculture
For researchers who study Earth's past environment, disentangling the effects of climate change from those related to human activities is a major challenge, but now University of Massachusetts Amherst geoscientists have used a biomarker from human feces in a completely new way to establish the first human presence, the arrival of grazing animals and human population dynamics in a landscape.

Ancient Microbes Found Living Beneath the Icy Surface of Antarctic Lake
This week a pioneering study published in the Proceedings of the National Academy of Sciences (PNAS) and co-authored by Dr. Alison Murray and Dr. Christian Fritsen of Nevada's Desert Research Institute (DRI) reveals, for the first time, a viable community of bacteria that survives and ekes out a living in a dark, salty and subfreezing environment beneath nearly 20 meters of ice in one of Antarctica's most isolated lakes.

'Pac-Man' Moons: Cassini Finds a Video Gamers' Paradise at Saturn
You could call this "Pac-Man, the Sequel." Scientists with NASA's Cassini mission have spotted a second feature shaped like the 1980s video game icon in the Saturn system, this time on the moon Tethys. (The first was found on Mimas in 2010). The pattern appears in thermal data obtained by Cassini's composite infrared spectrometer, with warmer areas making up the Pac-Man shape.

Do Missing Jupiters Mean Massive Comet Belts?
Using ESA's Herschel space observatory, astronomers have discovered vast comet belts surrounding two nearby planetary systems known to host only Earth-to-Neptune-mass worlds. The comet reservoirs could have delivered life-giving oceans to the innermost planets.

For Some Feathered Dinosaurs, Bigger Not Always Better
Every kid knows that giant carnivores like Tyrannosaurus rex dominated the Cretaceous period, but they weren't the only big guys in town. Giant plant-eating theropods -- close relatives of both T. rex and today's birds -- also lived and thrived alongside their meat-eating cousins. Now researchers have started looking at why dinosaurs that abandoned meat in favor of vegetarian diets got so big, and their results may call conventional wisdom about plant-eaters and body size into question.

Thought-Controlled Prosthesis Changing Lives of Amputees
The world's first implantable robotic arm controlled by thoughts is being developed by Chalmers researcher Max Ortiz Catalan. The first operations on patients will take place this winter.

Human Genetic Variation Recent, Varies Among Populations
Nearly three-quarters of mutations in genes that code for proteins -- the workhorses of the cell -- occurred within the past 5,000 to 10,000 years, fairly recently in evolutionary terms, said a national consortium of genomic and genetic experts, including those at Baylor College of Medicine.
