Carbon nanotubes carry plasmonic signals in the terahertz range of the electromagnetic spectrum, but only if they’re metallic by nature or doped. In new research, the Rice University laboratory of physicist Junichiro Kono disproved previous theories that dominant terahertz response comes from narrow-gap semiconducting nanotubes.
Scientists from the University of New Hampshire and colleagues have published comprehensive findings on space-based radiation as measured by a UNH-led detector aboard NASA's Lunar Reconnaissance Orbiter (LRO). The data provide critical information on the radiation hazards that will be faced by astronauts on extended missions to deep space such as those to Mars.
Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices.
Lithium-air batteries have become a hot research area in recent years: They hold the promise of drastically increasing power per battery weight, which could lead, for example, to electric cars with a much greater driving range.
Anyone who's stuffed a smart phone in their back pocket would appreciate the convenience of electronic devices that could bend. Flexible electronics could spawn new products: clothing wired to cool or heat, reading tablets that could fold like newspaper, and so on.
UCLA computer science professor Amit Sahai and a team of researchers have designed a system to encrypt software so that it only allows someone to use a program as intended while preventing any deciphering of the code behind it. This is known in computer science as "software obfuscation," and it is reportedly the first time it has been accomplished.
There is only one planet we know of, so far, that is drenched with life. That planet is Earth, as you may have guessed, and it has all the right conditions for critters to thrive on its surface. Do other planets beyond our solar system, called exoplanets, also host life forms?
A new study estimates that global sea levels will rise about 2.3 meters, or more than seven feet, over the next several thousand years for every degree (Celsius) the planet warms.
At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed with phytoplankton, amoeba-like foraminifera and other tiny creatures, who thrived in large numbers until the productivity ended — as mysteriously as it began — just a few hundred years later.
Researchers from North Carolina State University have developed three-dimensional (3-D) printing technology and techniques to create free-standing structures made of liquid metal at room temperature.
Bees use the electric fields that build up on their body to communicate without the need for mobile phones.
NASA scientists are currently researching ways of safely sending astronauts to Mars using advanced nuclear rockets.
It's not just artistic types that find math a turn-off and try to avoid having to deal with it - scientists do the same.
The US Food and Drug Administration routinely monitored the personal e-mail of certain FDA scientists and doctors after they warned Congress the agency was approving risky medical devices.
As US policymakers debate cutting science spending, more than 140 scientific societies and universities have joined forces to urge US policymakers not to cut out entire programs.
Did you know that China is governed by scientists? Yes, both the Chinese President and his Premier are engineers. In addition, 8 out of China’s top 9 government officials are scientists.
Who knew the perks of being a research scientist could be so good? But the Southwest Research Insitute has handed over $1.6 million to Virgin Galactic to fly some of its staff into space.
US scientists are significantly more likely to publish fake research than scientists from elsewhere, a study of officially withdrawn studies shows.
US climate scientists say they're experiencing a barrage of hate mail and death threats, and that law enforcement agencies are failing to act.
