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
The latest Snowden-supplied bombshell shook the technology world to its core on Thursday: The NSA can crack many of the encryption technologies in place today, PC World reports — a day after Pew reported that 90 percent of Internet users have taken steps to avoid surveillance in some way.
PC World recommends several open-source encryption tools, such as… read more
On October 26th, the 12th anniversary of the signing of the USA Patriot Act, StopWatching.us — a coalition of more than 100 public advocacy organizations and companies from across the political spectrum — is holding the largest rally yet against NSA surveillance.
According to StopWatching.us:
The revelations about the National Security Agency’s surveillance apparatus, if true, represent a stunning abuse of our basic rights. We demand the… read more
A common vitamin — riboflavin (vitamin B2) — has made it possible to 3D-print non-toxic medical implants, researchers from North Carolina State University, the University of North Carolina at Chapel Hill and Laser Zentrum Hannover have discovered.
“This opens the door to a much wider range of biocompatible implant materials, which can be used to develop customized implant designs using 3-D printing technology,” says Dr.… read more
Researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital have developed a way to deliver a light signal to specific tissues deep within the body for sensing or treatment.
The use of light to communicate with cells has previously been restricted by its limited ability to pass through tissues, especially the skin.
Called a light-guiding hydrogel, the implant is constructed from a polymer-based scaffolding capable of… read more
NASA‘s Lunar Laser Communication Demonstration (LLCD) has made history using a pulsed laser beam to transmit data over the 239,000 miles between the moon and Earth at a record-breaking download rate of 622 megabits per second (Mbps).
LLCD is NASA’s first system for two-way communication using a laser instead of radio waves. It also has demonstrated an error-free data upload rate… read more
Despite a long-held scientific belief that cortex is built up by repeatedly occurring elementary units called cortical columns, a new study by neuroscientists has found that the structure of the brain’s cortical columns can largely deviate within individual animals, and even within a specific cortical area.
The study also found that these structural differences are not arbitrary, but reflect organizational and functional properties of the… read more
New technology in 3-D printing has reached the art world. The race is on to produce high-quality 3-D reproductions of masterpieces by such artists as Rembrandt and Vincent van Gogh, The New York Times reports.
This year the Van Gogh Museum in Amsterdam teamed up with Fujifilm in Japan to produce the first fully color-corrected three-dimensional copies of some of van… read more
Researcher Dr. Jeroen de Vries from the University of Twente MESA+ Institute for Nanotechnology suggests we could store data for one million to one billion years, using a new storage medium based on tungsten and graphene oxide.
He imagines two possible scenarios:
