Hybrid nanowires eyed for computers, flexible displays
A new process for coating copper nanowires with graphene - an ultrathin layer of carbon – lowers resistance and heating, suggesting potential applications in computer chips and flexible displays.
'Inverse opal' structure improves thin-film solar cells
(Phys.org) —Researchers have shown how to increase the efficiency of thin-film solar cells, a technology that could bring low-cost solar energy. The approach uses 3-D "photonic crystals" to absorb more ...
Some volcanoes 'scream' at ever-higher pitches until they blow their tops
It is not unusual for swarms of small earthquakes to precede a volcanic eruption. They can reach a point of such rapid succession that they create a signal called harmonic tremor that resembles sound made ...

Origami-inspired paper sensor could test for malaria and HIV for less than 10 cents
Inspired by the paper-folding art of origami, chemists at The University of Texas at Austin have developed a 3-D paper sensor that may be able to test for diseases such as malaria and HIV for less than 10 ...
New dinosaur's keen nose made it a formidable predator, study finds
A researcher from the University of Pennsylvania has identified a species of dinosaur closely related to Velociraptor, the group of creatures made infamous by the movie "Jurassic Park." The newly named specie ...
Research probes temperature-dependent sex determination in turtles
Thane Wibbels, Ph.D., professor of biology in the University of Alabama at Birmingham College of Arts and Sciences, used to go out in the wild to catch turtles.
Scientists uncover four-stranded elements of maize DNA
A team led by Florida State University researchers has identified DNA elements in maize that could affect the expression of hundreds or thousands of genes.
Diversified farming practices might preserve evolutionary diversity of wildlife
As humans transform the planet to meet our needs, all sorts of wildlife continue to be pushed aside, including many species that play key roles in Earth's life-support systems. In particular, the transformation ...
Paleontologists describe a possible dinosaur nest and young 'babysitter'
Dinosaurs are often depicted as giant, frightening beasts. But every creature is a baby once.
Antineutrino detectors could aid non-proliferation
Physicists at the Large Hadron Collider in Switzerland and even in the fictional world of CBS' "The Big Bang Theory" look to subatomic particles called neutrinos to answer the big questions about the universe.
Chemical transport in human membranes likened to that of plants
Plant roots and certain human membrane systems resist chemical transport in much the same way, say researchers at Missouri University of Science and Technology in a recent journal article. This similarity ...
Rising mountains dried out Central Asia, scientists say
(Phys.org) —A record of ancient rainfall teased from long-buried sediments in Mongolia is challenging the popular idea that the arid conditions prevalent in Central Asia today were caused by the ancient ...
Scientists use new approach to reveal function of Greenland's ice sheet
(Phys.org) —Findings from a large-scale ice drilling study on the Greenland ice sheet by a team of University of Montana and University of Wyoming researchers may revise the models used to predict how ice ...
