MIT researchers have found that Kepler 78b, a small, intensely hot planet 400 light-years from Earth discovered by the researchers in August, shares Earth’s mass.
By analyzing the movement of its host star, Kepler 78, the scientists determined that the exoplanet is about 1.7 times as massive as the Earth.
From the same measurements, they calculated that the planet’s density is 5.3 grams… read more
In a possible first, Cecilia Abadie received a traffic ticket Tuesday for wearing Google Glass while driving in San Diego, she noted on Google+:
According to CNN, the California law cited in Abadie’s case, V C 27602, prohibits televisions and similar monitors from being turned on and facing the driver. “There are exceptions for GPS and mapping tools and… read more
A unique nanostructure developed by a team of international researchers* promises improved all-in-one detection, diagnoses, and drug-delivery treatment of cancer cells.
It can carry a variety of cancer-fighting materials on its double-sided (Janus) surface and within its porous interior and can:
The NSA has secretly broken into fiber-optic cables that connect Yahoo and Google data centers around the world — positioning itself to collect at will from hundreds of millions of user accounts, many of them belonging to Americans, according to documents obtained from former NSA contractor Edward Snowden and interviews with knowledgeable officials, the Washington Post reported today.
According to a top-secret accounting dated… read more
An orally administered compound that prevents neurodegeneration in mice has been developed by researchers at the Medical Research Council (MRC) Toxicology Unit at the University of Leicester.
The team had found previously (Nature) that the build up of misfolded proteins in the brains of mice with prion disease over-activates a natural defense mechanism in cells, which switches off the production of new proteins.… read more
Arizona State University and Georgia Institute of Technology researchers have developed a new approach to growing indium gallium nitride (InGaN) crystals, promising “record-breaking” photovoltaic solar cell efficiencies.
Researchers previously found that the atomic separation of the crystal layers of the InGaN alloy varies, which can lead to high levels of strain, breakdowns in growth, and fluctuations in the alloy’s chemical composition.
“Being able to ease… read more
Out of shape and can’t lift something? No prob, just strap on an external bicep — the Titan Arm, a new invention from a group of engineering students at the University of Pennsylvania.
That’s if it’s ever available commercially (co-inventor Nick McGill told KurzweilAI they’re working on it, no date yet). If so, the Titan Arm will help lift 40 pounds more than you normally can.… read more
A silicon nanomembrane developed at the University of Rochester could drastically shrink the power source needed with electroosmotic pumps (EOPs) to move solutions through micro-channels — paving the way for ultra-thin ”lab-on-a-chip” diagnostic devices the size of a credit card.
“Until now, electroosmotic pumps have had to operate at a very high voltage — about 10 kilovolts,” said James McGrath, associate professor of biomedical… read more
Scientists at MIT and elsewhere have developed a tool that could test to see if dark matter is detectable.
That will be a challenge: dark matter, believed by physicists to outweigh all the normal matter in the universe by more than five to one, is by definition invisible.
However, the MIT researchers have come up with a workaround, described in a paper in the journal Physical… read more
NASA’s Hubble, Spitzer, and Chandra space telescopes are teaming up to look deeper into the universe than ever before.
With a boost from natural “zoom lenses” found in space, they should be able to uncover galaxies that are as much as 100 times fainter than what these three great observatories typically can see.
The Frontier Fields
The National Science Foundation (NSF), in partnership with NIH, USDA and NASA, has announced about $38 million in investment for developing robots that cooperatively work with people to enhance individual human capabilities, performance and safety.
Co-robots
The 30 new projects, funded projects target the creation of next-generation collaborative robots (co-robots) for advanced manufacturing; civil and environmental infrastructure; health care and rehabilitation; military and homeland… read more
University of North Carolina at Chapel Hill researchers have discovered that dendrites do more than passively relay information from one neuron to the next — they actively process information, according to Spencer Smith, PhD, an assistant professor in the UNC School of Medicine.
Axons are where neurons conventionally generate electrical spikes, but many of the same molecules that support axonal electrical spikes (firing) are also present… read more
The Oxford Martin Commission for Future Generations has launched a report, Now for the Long Term, on the successes and failures in addressing global challenges over recent decades.
Published by the Oxford Martin School at Oxford University, the report calls for a radical shake-up in politics and business to deliver progress on climate change, reduce economic inequality, improve corporate practices, and address the chronic… read more
Three projects have been awarded funding by the National Institutes of Health to develop innovative robots that work cooperatively with people and adapt to changing environments to improve human capabilities and enhance medical procedures. Funding for these projects totals approximately $2.4 million over the next five years, subject to the availability of funds.
The awards mark the second year of NIH’s participation in the National… read more
Vicarious, a startup developing artificial intelligence software, today announced that its algorithms can now reliably solve modern CAPTCHAs (Completely Automated Public Turing tests to tell Computers and Humans Apart).
Stanford University researchers have suggested that a CAPTCHA scheme (which are used by websites to verify that a visitor is human by asking them to transcribe a string of distorted letters) should be considered “broken” if an algorithm… read more
