Simulation of a double impact reveals the heart of an asteroid
Models boost the significance of image and measurement data from space missions and help to understand our solar system. A simulation of a double impact that occurred on the proto-planet Vesta one billion ...
Scientists confirm original tetrahedral model of the molecular structure of water
Researchers at Johannes Gutenberg University Mainz (JGU) have confirmed the original model of the molecular structure of water and have thus made it possible to resolve a long-standing scientific controversy about the structure ...
Professor sees clouds as key to better weather forecast, climate predictions
Zhien Wang makes no bones about it. He believes meteorologists could do a better job of predicting the weather. To do so, he believes the clues are in the clouds.
Computer modeling breaks new ground in study of root architecture
(Phys.org)—The UN estimates that one in every seven people around the world are hungry. Fortunately, Jonathan Lynch uses Information Technology (IT) to get to the root of this problem.
Research group suggests Chicxulub crater may have been caused by binary asteroids
Synchrotrons explore water's molecular mysteries
(Phys.org)—In experiments at SLAC National Accelerator Laboratory and Lawrence Berkeley National Laboratory, scientists observed a surprisingly dense form of water that remained liquid well beyond its typical ...
Computer scientists developing tools to reduce greenhouse gases at the source
Despite advances in alternative energy sources, the United States will continue to rely on coal-fired power plants to generate much of the nation's electricity for the next 20 years or more. While coal is ...
Cyclone did not cause 2012 record low for Arctic sea ice
A huge Arctic cyclone in August was not responsible for the historic minimum seen soon after in Arctic sea-ice extent.
When fairness prevails: Research shows how uncertainty affects behavior
Philosophers and scientists have long puzzled over the origins of fairness. Work by a group of Harvard researchers offers some clues, with the discovery that uncertainty is critical in the concept's development.
Work needed to make algal biofuel viable, study suggests
(Phys.org)—Though biofuels from algae hold great promise, Cornell researchers find that more innovation is needed to make the technology economically and energetically viable at a commercial scale.
Computational chemistry: A faster way to untangle intermolecular interactions
A powerful computational technique used by the pharmaceutical industry to expedite new drug development has just received a performance boost. Chandra Verma and his co-workers at the A*STAR Bioinformatics ...
Ants' behavior leads to new method for optimizing product development time, costs
Trying to find just the right balance of time spent in meetings and time performing tasks is a tough problem for managers, but a Wayne State University researcher believes the behavior of ants may provide a useful lesson ...
What can go wrong when computer simulations applied outside their original context
In an article about to be published in European Physical Journal Plus, Daan Frenkel from the University of Cambridge, UK, outlines the many pitfalls associated with simulation methods such as Monte Carlo algorithms or oth ...
One in, two out: Simulating more efficient solar cells
(Phys.org)—Using an exotic form of silicon could substantially improve the efficiency of solar cells, according to computer simulations by researchers at the University of California, Davis, and in Hungary. ...
