Structure of 450 million year old protein reveals evolution's steps
A detailed map that pinpoints the location of every atom in a 450-million-yeard-old resurrected protein reveals the precise evolutionary steps needed to create the molecule's modern version, according to researchers from the University of North Carolina at Chapel Hill and the University of Oregon.
Researchers evaluate algae jet fuel
ASU researchers are part of a team led by UOP, a Honeywell company that is looking at alternative sources of oil that could be used to produce Jet Propellant 8 (JP-8) or military jet fuel.
Silicon nanoparticles enhance performance of solar cells
Placing a film of silicon nanoparticles onto a silicon solar cell can boost power, reduce heat and prolong the cell's life, researchers now report.
Working toward new energy with electrochemistry
In an effort to develop alternative energy sources such as fuel cells and solar fuel from "artificial" photosynthesis, scientists at the U.S. Department of Energy's Brookhaven National Laboratory are taking a detailed look at electrons - the particles that set almost all chemical processes in motion.
New cancer weapon: nuclear nanocapsules
Rice University chemists have found a way to package some of nature's most powerful radioactive particles inside DNA-sized tubes of pure carbon -- a method they hope to use to target tiny tumors and even lone leukemia cells.
Neurotransmitter current not flowing through ion channels
In studying how neurotransmitters travel between cells -- by analysis of events in the dimensions of nanometers -- Cornell researchers have discovered that an electrical current thought to be present during that process does not, in fact, exist.
New finding bubbles to surface, challenging old view
Chemical engineers have discovered a fundamental flaw in the conventional view of how liquids form bubbles that grow and turn into vapors, which takes place in everything from industrial processes to fizzing champagne.
Amber specimen captures ancient chemical battle
It appears that chemical warfare has been around a lot longer than poison arrows, mustard gas or nerve weapons – about 100 million years, give or take a little.
How drones find queens: odorant receptor for queen pheromone identified
The mating ritual of the honey bee is a mysterious affair, occurring at dizzying heights in zones identifiable only to a queen and the horde of drones that court her. Now a research team led by the University of Illinois has identified an odorant receptor that allows male drones to find a queen in flight. The receptor, on the male antennae, can detect an available queen up to 60 meters away.
Chemists get grip on slippery lipids
The ability of the body's cells to correctly receive and convey signals is crucial to good health.

New catalysts may create more, cheaper hydrogen
A new class of catalysts created at the U.S. Department of Energy's Argonne National Laboratory may help scientists and engineers overcome some of the hurdles that have inhibited the production of hydrogen for use in fuel cells.
Tiny tubes and rods show promise as catalysts, sunscreen
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed new ways to make or modify nanorods and nanotubes of titanium oxide, a material used in a variety of industrial and medical applications. The methods and new titanium oxide materials may lead to improved catalysts for hydrogen production, more efficient solar cells, and more protective sunscreens.

Chemists explain the origin of soil-scented geosmin
Brown University chemists have found the origins of an odor – the sweet smell of fresh dirt. In Nature Chemical Biology, the Brown team shows that the protein that makes geosmin – source of the good earth scent – has two similar but distinct halves, each playing a critical role in making this organic compound.
Advance in creating inexpensive polarized light may lead to better displays on laptop computers, cell phones and other devices
UCLA chemists working at the nanoscale have developed a new, inexpensive means of forcing luminescent polymers to give off polarized light and of confining that light to produce polymer-based lasers.
Scientists demonstrate efficient electrical spin injection into silicon
Scientists at the Naval Research Laboratory have efficiently injected a current of spin-polarized electrons from a ferromagnetic metal contact into silicon, producing a large electron spin polarization in the silicon.
New delft material concept for aircraft wings could save billions
Building aircraft wings with a special aluminium fibre combination makes them nearly immune to metal fatigue. The application of this technology, partly developed at Delft University of Technology, will lead to substantial savings.
Engineered eggshells to help make hydrogen fuel
Engineers at Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource.
A liquid metal that's not really metallic
When melting sodium at high pressures, the material goes through a transition in which its electrical conductivity drops threefold.
Census of protein architectures offers new view of history of life
The present can tell you a lot about the past, but you need to know where to look. A new study appearing this month in Genome Research reveals that protein architectures – the three-dimensional structures of specific regions within proteins – provide an extraordinary window on the history of life.
