Mimicking polar bear fur, which is able to insulate the animal's body to temperatures of 9...

Put a polar bear and a biophotonics expert together in a chilly room and what do you get? Potentially, better insulation. When looking to uncover the secrets of the impressive insulation properties of polar bear fur, researchers at the University of Namur in Belgium and the University of Hassan I in Morocco found that radiation plays a larger role than conduction in the insulation of polar animals, such as penguins and polar bears, than previously believed.  Read More

A cloudy night in London led to the discovery of the 21st Century's brightest supernova to date. The new supernova 2014J, the brightest since 1993, is located in the galaxy M82. This Type-Ia supernova has just reached its peak brightness of magnitude 10.6. M82 lies at a distance of only about 12 million light years, which explains the brightness of 2014J in our skies. 2014J is bright enough to be seen in small telescopes or perhaps in (very) large binoculars. We'll tell you how to find it.  Read More

A fruit fly sits on a podium in the middle of the picture, while scents are emitted from t...

Scientists from the University of Konstanz, Germany, are the first to demonstrate that fruit flies can distinguish cancerous cells from healthy ones via their sense of smell. The team has genetically modified fruit flies so that their antennae glow when they detect a cancerous odor. In an experiment, scientists directed smells at fruit flies. The fruit flies' appearance was monitored via a microscope.  Read More

Astrophoto in redshifted Lyman-alpha light, possibly emitted by a cosmic filament of gas a...

That the Universe is largely composed of a cosmic web consisting of narrow filaments upon which galaxies and intergalactic gas and dust are concentrated has been known for more than a decade. While a great deal of evidence for this has accumulated, visual evidence has been difficult to find. Astronomers have now photographed what appears to be a segment of a cosmic filament stimulated into fluorescence by irradiation from a nearby quasar.  Read More

The same structure that gives seashells their strength has been replicated in glass  (Phot...

In the future, if you drop a glass on the floor and it doesn't break, thank a mollusk. Inspired by shellfish, scientists at Montreal's McGill University have devised a new process that drastically increases the toughness of glass. When dropped, items made using the technology would be more likely to deform than to shatter.  Read More

In the game EteRNA, players are asked to solve puzzles that predict how RNA will fold once...

Results from the crowdsourced game and experiment, EteRNA, which combines RNA folding puzzles with laboratory synthesis, show that human gamers are able to develop better models of RNA folding than previous computer algorithms. Design rules formulated by the online community have even been used to construct a new algorithm, EteRNABot, and in some cases represent completely new understandings about RNA folding that have yet to be explained mechanically.  Read More

A team of interdisciplinary researchers have created "smart" holograms that can monitor health conditions or diagnose diseases, by changing color in the presence of disease indicators in a person's breath or bodily fluids. When developed into a portable medical test, these responsive holograms could make testing for medical conditions and monitoring one's health very easy, the scientists claim.  Read More

The spherical middle chamber of DarkSide-50 is filled with 7,000 gal of scintillator fluid

Like the Higgs Boson, dark matter is one of those things in the Universe that evidence points to, but is very difficult to pin down. A team of researchers is looking to verify the existence of this most elusive of ingredients that is thought to make up 23 percent of the Universe using powerful detectors buried deep in an Italian mountain.  Read More

The blue cloud of strontium at the heart of the world's most precise and stable clock (Pho...

Not satisfied with the accuracy of the "quantum logic clock" (which only gains or loses one second every 3.7 billion years), the National Institute of Standards and Technology (NIST) and JILA have unveiled an even more precise timekeeper. The strontium lattice clock sets new standards for precision and stability, only gaining or losing one second about every five billion years.  Read More

The good ol' red, white and blue – turkeys show off their color-changing skin (Photo: Shut...

Turkeys may not be everyone's idea of beautiful birds, but they certainly have colorful skin on their heads. What's more, that skin changes color with the animal's mood. Scientists at the University of California, Berkeley, have now copied the process by which those color changes occur, and used it to create a biosensor that could be used to detect airborne toxins.  Read More
