Study casts doubt on climate benefit of biofuels from corn residue
Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change.
Team finds electricity can be generated by dragging saltwater over graphene
Researchers model world's first carbon-based 'spaser'
(Phys.org) —A new version of "spaser" technology being investigated could mean that mobile phones become so small, efficient, and flexible they could be printed on clothing.
Switchable material could harness the power of the sun—even when it's not shining
It's an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn't shine.
New materials for capturing carbon dioxide from combustion gases
(Phys.org) —Carbon dioxide is both a culprit in global warming and also responsible for keeping the Earth warm enough to support life as we know it. It is odorless and colorless, often represented by a ...
Gusev Crater once held a lake after all, Mars scientist says
(Phys.org) —If desert mirages occur on Mars, "Lake Gusev" belongs among them. This come-and-go body of ancient water has come and gone more than once, at least in the eyes of Mars scientists.
Scientists discover a novel way to make ethanol without corn or other plants
Stanford University scientists have found a new, highly efficient way to produce liquid ethanol from carbon monoxide gas. This promising discovery could provide an eco-friendly alternative to conventional ...
Hybrid nanotube-graphene material promises to simplify manufacturing
(Phys.org) —Carbon nanotubes are reinforcing bars that make two-dimensional graphene much easier to handle in a new hybrid material grown by researchers at Rice University.
Arid areas absorb unexpected amounts of atmospheric carbon
Researchers led by a Washington State University biologist have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide ...
Methane-producing microbes may be responsible for the largest mass extinction in Earth's history
Evidence left at the crime scene is abundant and global: Fossil remains show that sometime around 252 million years ago, about 90 percent of all species on Earth were suddenly wiped out—by far the largest ...

Turning graphite into diamond
(Phys.org) —A research team led by SLAC scientists has uncovered a potential new route to produce thin diamond films for a variety of industrial applications, from cutting tools to electronic devices to ...
Nanotube coating helps shrink mass spectrometers
Nanotechnology is advancing tools likened to Star Trek's "tricorder" that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety.
Researchers grow carbon nanofibers using ambient air, without toxic ammonia
(Phys.org) —Researchers from North Carolina State University have demonstrated that vertically aligned carbon nanofibers (VACNFs) can be manufactured using ambient air, making the manufacturing process ...
