Thousands rally in Australia for climate action
Thousands of people on Sunday rallied across Australia calling for stronger action on climate change, days after new conservative Prime Minister Tony Abbott moved to abolish a carbon tax.
Researchers predict Cyclone Haiyan likely to release huge amount of carbon
Researchers develop technique for imaging individual carbon nanotubes
(Phys.org) —Despite their almost incomprehensibly small size – a diameter about one ten-thousandth the thickness of a human hair – single-walled carbon nanotubes come in a plethora of different "species," ...
Nanotubes can solder themselves, markedly improving device performance (w/ Video)
University of Illinois researchers have developed a way to heal gaps in wires too small for even the world's tiniest soldering iron.
Carbon nanotube field electron emitters will get space testing
A pair of carbon nanotube arrays will be flying in space by the end of the year to test technology that could provide more efficient micro-propulsion for future generations of spacecraft. Part of a Cube Satellite ...
In plant photosynthesis, scientists see clues for improving solar energy cells
Solar cells optimized to suit local light conditions, or made more efficient by using a broader part of the solar spectrum, are among the imaginative applications foreseen from ground-breaking new insights ...
Could dying planets harbor life?
If life does exist anywhere else in the universe, it may only be fleeting. Now scientists are researching how signs of life might look on dying planets.
UN panel issues corrections for climate report
UN climate scientists have issued corrections to the summary of a key report on global warming issued in September.
Worlds first commercial nanostructured bulk metal
When we think of structural materials, we usually imagine something big, strong and bulky, like steel beams in bridges and buildings, and while we are becoming familiar with composites reinforced with carbon ...
Scientists scale terahertz peaks in nanotubes
(Phys.org) —Carbon nanotubes carry plasmonic signals in the terahertz range of the electromagnetic spectrum, but only if they're metallic by nature or doped.
Expert assessment: Ocean acidification may increase 170 percent this century
In a major new international report, experts conclude that the acidity of the world's ocean may increase by around 170% by the end of the century bringing significant economic losses. People who rely on the ocean's ecosystem ...
Ocean crust could store many centuries of industrial carbon dioxide
Researchers from the University of Southampton have identified regions beneath the oceans where the igneous rocks of the upper ocean crust could safely store very large volumes of carbon dioxide.
Researchers improve the nanopore-based technology for detecting DNA molecules
If we wanted to count the number of people in a crowd, we could make on the fly estimates, very likely to be imprecise, or we could ask each person to pass through a turnstile. The latter resembles the model ...
Amber provides new insights into the evolution of the Earth's atmosphere
An international team of researchers led by Ralf Tappert, University of Innsbruck, reconstructed the composition of the Earth's atmosphere of the last 220 million years by analyzing modern and fossil plant ...
