At this year’s South by Southwest, the most talked-about start-ups this year include the maker of a camera that automatically takes a photo every 30 seconds, a new game console, and a gadget that lets people control their computers and devices by waving their hands, The New York Times reports.
At least two dozen panels, talks and presentations involve some… read more
A petition to the White House to task the White House Office of Science and Technology Policy to examine space solar power (SSP) as a new energy and space goal for the U.S. has been posted on the White House WE the PEOPLE website, with a goal of 100,000 signatures by April 3, 2013.
The petition, initiated by SSP pioneer John C. Mankins,… read more
A 70-pound “cheetah” robot designed by MIT researchers may soon outpace its animal counterparts in running efficiency.
In treadmill tests, the researchers have found that the robot — about the size and weight of an actual cheetah — wastes very little energy as it trots continuously for up to an hour and a half at 5 mph.
The key to the robot’s streamlined stride:… read more
Researchers at the University of Michigan have found a new potential benefit of a molecule in green tea: preventing the misfolding of specific proteins in the brain.
U-M Life Sciences Institute faculty member Mi Hee Lim and an interdisciplinary team of researchers used green tea extract to control the generation of metal-associated amyloid-β aggregates associated with Alzheimer’s disease in the lab.
The specific molecule… read more
The flip of a single molecular switch helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability.
Now Yale School of Medicine researchers have reversed the process, recreating a youthful brain that facilitated both learning and healing in the adult mouse.
Scientists have long known that the young and old brains are very different.… read more
The human brain can learn to treat relevant prosthetics as a substitute for a non-working body part, according to research published March 6 in the open access journal PLOS ONE by Mariella Pazzaglia and colleagues from Sapienza University and IRCCS Fondazione Santa Lucia of Rome in Italy, supported by the International Foundation for Research in Paraplegie.
The researchers found that wheelchair-bound study participants with spinal cord injuries perceived their… read more
The Human Connectome Project, a five-year endeavor to link brain connectivity to human behavior, has released a set of high-quality imaging and behavioral data to the scientific community.
The project has two major goals: to collect vast amounts of data using advanced brain imaging methods on a large population of healthy adults, and to make the data freely available so that scientists worldwide can make… read more
Swedish scientists have developed “theranostic” (having both a therapeutic and diagnostic function) nanoparticles that can carry cancer drugs to tumor cells without toxicity and are biodegradable and traceable (can be seen in MRI images).
The nanoparticles were developed by a team including KTH Royal Institute of Technology Professor Eva Malmström-Jonsson, from the School of Chemical Science and researchers at Sweden’s Chalmer’s University and the Karolinska… read more
Glial cells — a family of cells found in the human central nervous system and, until recently, considered mere “housekeepers” — now appear to be essential to the unique complexity of the human brain.
Scientists reached this conclusion after demonstrating that when transplanted into mice, these human cells could influence communication within the brain, allowing the animals to learn more rapidly.
The study suggests that the… read more
Google is creating high expectations that Google Glass will become a mass-market device, MIT Technology Review reports.
A new company, Augmedix, is making a Google Glass app for doctors, not for their patients. Founder Ian Shakil says his company is already testing it with medical facilities using the Vuzix M100, another smart glasses gadget coming out this year.
If you are a fan of action sports you have probably already noticed that putting tiny cameras on people’s heads — and in other unlikely locations — has become big business, BBC News reports.
Pivothead is putting superior technology into sunglasses worn by highway patrol officers in places like Austin, Texas. The glasses are able to capture the details of a driver’s face in high-definition… read more
Cal tech and NASA JPL researchers have found the strongest evidence yet that salty water from the vast liquid ocean beneath Europa’s frozen exterior actually makes its way to the surface.
The finding, based on some of the best data of its kind since NASA’s Galileo mission (1989 to 2003) to study Jupiter and its moons, suggests there is a chemical exchange between the ocean and surface,… read more
A team of entrepreneurs has awarded its first round of a $3-million Breakthrough Prize in Life Sciences, Nature News Blog reports.
Last summer, Russian social media magnate Yuri Milner awarded the first Fundamental Physics Prizes, a series of $3-million awards to theoretical physicists.
Now he has decided to invite biologists to the party, uniting with former Genentech chief executive Art Levinson,… read more
A new experiment simulating conditions in deep space reveals that the complex building blocks of life could have been created on icy interplanetary dust and then carried to Earth aboard a comet or possibly meteorites, jump-starting life.
Chemists from the University of California, Berkeley, and the University of Hawaii, Manoa, showed that conditions in space are capable of creating complex dipeptides — linked pairs of… read more
Working with bioengineers and neurosurgeons, Daniel Lim, a neurosurgeon and stem-cell scientist at the University of California, San Francisco, has designed a needle that bends for for delivering stem cells to the brain, Nature News reports.
The device can deposit cells anywhere within a 2-centimetre radius along a track, a volume bigger than an entire mouse brain.
Several researchers hope to use Lim’s device for clinical trials… read more
