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
The global pattern of e-mail communication reflects the cultural fault lines thought to determine future conflict, say computational social scientists.
In 1992, the Harvard-based political scientist Samuel Huntington suggested that future conflicts would be driven largely by cultural differences. He went on to map out a new world order in which the people of the world are divided into nine culturally distinct civilizations.
His argument was that future… read more
Electrically stimulating the brain may enhance memory, but impede a person’s ability to react without thinking, MIT Technology Review reports.
Using a noninvasive technique called transcranial electrical stimulation (TES) to stimulate the brain, researchers found they could enhance learning when they targeted a certain spot.
But that also made people worse at automaticity, or the ability to perform a task without really thinking about it. Stimulating another… read more
It is possible to tell who a person is thinking about by analyzing images of his or her brain.
Our mental models of people produce unique patterns of brain activation, which can be detected using advanced imaging techniques according to a study by Cornell University neuroscientist Nathan Spreng and his colleagues.
“When we looked at our data, we were shocked that we could successfully… read more
A multi-university team of researchers has engineered a unique multilayer material designed to achieve extraordinary superconducting properties — in particular, the ability to transport much more electrical current than non-engineered materials.
The team, led by Chang-Beom Eom, the Harvey D. Spangler Distinguished Professor of materials science and engineering and physics at UW-Madison, includes experts from the University of Wisconsin-Madison, Florida State University and the University… read more
Researchers at Georgia Tech have drawn up blueprints for a wireless antenna made from atom-thin sheets of carbon, or graphene, that could allow terabit-per-second transfer speeds at a range of about one meter, MIT Technology Review reports
This would make it possible to obtain 10 high-definition movies by waving your phone past another device for one second. At even shorter ranges, such as a few centimeters, data… read more
An international consortium of university researchers has produced the most comprehensive virtual reconstruction of human metabolism to date.
Scientists could use the model, known as Recon 2, to identify causes of and new treatments for diseases like cancer, diabetes and even psychiatric and neurodegenerative disorders. Each person’s metabolism, which represents the conversion of food sources into energy and the assembly of molecules,… read more
Researchers have demonstrated that graphene is highly efficient at generating electrons upon absorbing light, which suggests that the material could be used to make light sensors and perhaps even more efficient solar cells, MIT Technology Review reports.
Conventional materials that turn light into electricity, like silicon and gallium arsenide, generate a single electron for each photon absorbed. Since a photon contains more energy than one electron can… read more
An MIT research team has published a detailed analysis of all the factors that could limit the efficiency of an “artificial leaf” — a small device that, when placed in a container of water and exposed to sunlight, would produce bubbles of hydrogen and oxygen for storing energy.
The new analysis lays out a roadmap for a research program to improve the efficiency of these systems, and… read more
Technology is starting to give us superpowers once reserved for comic-book heroes, Slate reports.
Human enhancement is happening all the time, largely through incremental improvements on existing technologies.
Wearable technology is taking off. Muscle suits are starting to look more plausible. The military is working on “Spider-Man suits” that let the wearer scale vertical walls.
Devices that interact directly… read more
A diagnostic system using DNA powder and gold nanoparticles being developed by scientists at the University of Toronto’s Institute of Biomaterials and Biomedical Engineering could provide rapid point-of-care diagnosis of the world’s leading infectious diseases in the near future.
BBME PhD student Kyryl Zagorovsky has developed a rapid diagnostic biosensor that will allow technicians to test for multiple diseases at the same time with one… read more
