Cod inspire potentially life-saving cold storage tech for human blood

By - February 4, 2014
How is it possible that cold-blooded fish such as cod can live in Arctic waters without just freezing solid? As it turns out, they've got proteins in their bloodstream that act as a sort of antifreeze. British scientists have now copied the fashion in which those proteins work, to create a process by which donated human blood could be frozen for storage, then quickly made available for transfusion.

New stem cell production technique comes as a shock

By - February 3, 2014 2 Pictures
An international research effort has found that mature animal cells can be shocked into an embryonic state simply by soaking them in acid or putting them under physical stress. The fortuitous breakthrough could prove to be massive for many fields of medical research if the method can be replicated using human cells, something researchers are confident will be possible.

Graphene-based nano-antennas may enable cooperating smart dust swarms

By - February 3, 2014
Smart dust. Utility fog. Programmable matter. Grey and blue goo. Cooperating swarms of micron-sized devices (motes) offer completely new solutions and capabilities that can hardly be imagined. However, cooperation requires communication, and conventional radio or optical networking simply isn't practical at this size. Now researchers at Georgia Tech have invented a plasmonic graphene nano-antenna that can be efficiently used at millimeter radio wavelengths, taking one more step toward smart dust. Read More

Polar bear fur could hold secret to ultrathin insulation

By - February 2, 2014 2 Pictures
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.

The M82 supernova is at peak brightness: How to see it

By - January 31, 2014 5 Pictures
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

Scientists use fruit flies to detect cancer

By - January 30, 2014
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

Distant quasar lights up cosmic web like a neon sign

By - January 29, 2014 9 Pictures
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

Super-tough glass based on mollusk shells

By - January 29, 2014
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

Gamers outshine computers in crowdsourced RNA modeling

By - January 28, 2014 2 Pictures
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.
