Ghost protein leaves fresh tracks in the cell
Spectrin and ankyrin are two essential proteins acting like bricks and mortar to shape and fortify cell membranes. But distinguishing which protein is the brick and which is the mortar has turned out to be difficult. New evidence suggests that spectrin can do both jobs at once.
Ocean creatures linked to cloud cover increases
Atmospheric scientists have reported a new and potentially important mechanism by which chemical emissions from ocean phytoplankton may influence the formation of clouds that reflect sunlight away from our planet.
Z machine melts diamond to puddle
Sandia's Z machine, by creating pressures more than 10 million times that of the atmosphere at sea level, has turned a diamond sheet into a pool of liquid.
Scientists establish connection between life today and ancient changes in ocean chemistry
Researchers in computational biology and marine science have combined their diverse expertise and found that trace-metal usage by present-day organisms probably derives from major changes in ocean chemistry occurring over geological time scales.
An old discovery could boost ethanol production from plant fiber
John Verkade remembers just how it happened some 40 years ago: One of his Iowa State University graduate students, David Hendricker, stopped by to report somebody was stealing a little wooden applicator stick from a beaker.
Pulsating gels could power tiny robots
As a kid, did you ever put those little capsules into warm water and watch them grow into dinosaurs? When certain gels are put into a solution, they will not only expand, but also contract again, repeatedly, as if the little dinosaur grew and shrank over and over.
Edible food wrap kills deadly E. Coli bacteria
Researchers have improved upon an edible coating for fresh fruits and vegetables by enabling it to kill deadly E. coli bacteria while also providing a flavor-boost to food.
Nearly unbreakable
Scientists at the Max Planck Institute of Colloids and Interfaces have found a new design principle at the nanoscale which is responsible for the enormous stability and deformabilty of bone. They found that a piece of bone stretches more than the fibres and much more than the mineral it is composed of.
Early earth haze may have spurred life
Hazy skies on early Earth could have provided a substantial source of organic material useful for emerging life on the planet, according to a new study led by the University of Colorado at Boulder.
Chemists make tiny molecular rings with big potential
Ohio State University chemists have devised a new way to create tiny molecular rings that could one day function as drug delivery devices or antibiotics.

Tarantula venom and chili peppers target same pain sensor
Venom from a West Indian tarantula has been shown to cause pain by exciting the same nerve cells in mice that sense high temperatures and the hot, spicy ingredient in chili peppers, UCSF scientists have discovered.
'Nanorust' cleans arsenic from drinking water
The discovery of unexpected magnetic interactions between ultrasmall specks of rust is leading scientists at Rice University's Center for Biological and Environmental Nanotechnology (CBEN) to develop a revolutionary, low-cost technology for cleaning arsenic from drinking water. The technology holds promise for millions of people in India, Bangladesh and other developing countries where thousands of cases of arsenic poisoning each year are linked to poisoned wells.
Study reveals key compound for improving apple quality
The sugar-like compound called sorbitol may to play a key role in determining the characteristics of apples and may be a good target for plant breeders and geneticists trying to improve fruit quality in apple trees, according to a recent study by researchers at the University of California, Davis.
Agile new plastics change shape with heat
Researchers at MIT and the Helmholtz Association of German Research Centers have invented a class of materials so remarkable for their agility in changing shape as they react to heat, they might be described as acrobatic plastics.
Ultra-intense laser blast creates true 'black metal'
"Black gold" is not just an expression anymore. Scientists at the University of Rochester have created a way to change the properties of almost any metal to render it, literally, black.
Chemists create, grow nanotube seeds
Rice University chemists revealed the first method for cutting carbon nanotubes into "seeds" and using those seeds to sprout new nanotubes. The findings offer hope that seeded growth may one day produce the large quantities of pure nanotubes needed for dozens of materials applications.
Mystery solved
Answering a question that has lingered for centuries, a team of scientists has proved that chemicals used to treat the wood used in Stradivarius and Guarneri violins are the reasons for the distinct sound produced by the world-famous instruments.
Resilent form of plant carbon gives new meaning to term 'older than dirt'
A particularly resilient type of carbon from the first plants to regrow after the last ice age – and that same type of carbon from all the plants since – appears to have been accumulating for 11,000 years in the forests of British Columbia, Canada.
Mit's anti-microbial 'paint' kills flu, bacteria
A new "antimicrobial paint" developed at MIT can kill influenza viruses that land on surfaces coated with it, potentially offering a new weapon in the battle against a disease that kills nearly 40,000 Americans per year.
Microcapsules like it hot and salty
Scientists at the Max Planck Institute of Colloids and Interfaces have presented a new method with which to precisely control the permeability of microcapsules using the salt content and the temperature of the solution.
