Using microfluidic passages cut directly into the backsides of production field-programmable gate array (FPGA) devices, Georgia Institute of Technology researchers have put liquid cooling where it’s needed the most: a few hundred microns away from where the transistors are operating.

Combined with connection technology that operates through structures in the cooling passages, the new technologies could allow development of denser and more powerful integrated electronic… read more

Researchers have succeeded in transforming human support brain cells, called astroglial cells, into functioning neurons for brain repair.

The new technology opens the door to future development of drugs that patients could take as pills to regenerate neurons and to restore brain functions lost after traumatic injuries, stroke, or diseases such as Alzheimer’s.

Previous research, such as conventional stem-cell therapy, has required brain surgery, so it… read more

Surgeons reroute nerves to restore hand, arm movement to quadriplegic patients

A pioneering surgical technique has restored some hand and arm movement to nine patients immobilized by spinal cord injuries in the neck, reports a new study at Washington University School of Medicine in St. Louis.

Bypassing the spinal cord, the surgeons rerouted healthy nerves sitting above the injury site, usually in the shoulders or elbows, to paralyzed nerves in the hand or arm. Once a connection was established, patients… read more

Tesla Motors will introduce on Thursday (October 15, 2015) an advanced “beta test” set of autonomous driving features, The Wall Street Journal reports.

The software will allow hands- and feet-free driving in everything from stop-and-go traffic to highway speeds, and enables a car to park itself, the journal says. It will be available for 50,000 newer Model S cars world-wide via software… read more

Penn State University and University of Chicago researchers say an accidental discovery of a “quantum Etch-a-Sketch” may lead to a new way to use beams of light to draw and erase quantum circuits, and that could lead to the next generation of advanced computers and quantum microchips.

The new technique is based on “topological insulators” (a material that behaves as an insulator in… read more

Hybrid bio-robotic system models physics of human leg locomotion

Could help design optimal prosthetic and exoskeleton systems
October 14, 2015

bio-robotic system ft

North Carolina State University (NC State) researchers have developed a bio-inspired system that models how human leg locomotion works, by using a computer-controlled nerve stimulator (acting as the spinal cord) to activate a biological muscle-tendon.

The findings could help design robotic devices that begin to merge human and machine to assist human locomotion, serving as prosthetic systems for people with mobility impairments or exoskeletons for increasing the abilities… read more

The FDA has approved the first 3D-printed drug — Aprecia’s SPRITAM (levetiracetam) for oral use as a prescription adjunctive therapy in the treatment of seizures in adults and children with epilepsy.

SPRITAM manufacturing uses 3D printing to produce a porous formulation that rapidly disintegrates with a sip of liquid, making it easier to swallow.

The “ZipDose Technology” allows for delivering a high drug load, up to… read more

Imaging study shows you (and your fluid intelligence) can be identified by your brain activity

Your brain activity appears to be as unique as your fingerprints, a new Yale-led “connectome fingerprinting” study published Monday (Oct. 12) in the journal Nature Neuroscience has found.

By analyzing* “connectivity profiles” (coordinated activity between pairs of brain regions) of fMRI (functional magnetic resonance imaging) images from 126 subjects, the Yale researchers were able to identify specific individuals from the fMRI data alone by their… read more

A battery alternative to costly, rare lithium

Overturning nearly a century of a scientific dogma, Oregon State University chemists have now shown that  potassium could potentially replace rare, costly lithium in a new potassium-ion battery.

“For decades, people have assumed that potassium couldn’t work with graphite or other bulk carbon anodes in a battery,” said Xiulei (David) Ji, the lead author of the study and an assistant professor of chemistry… read more

New ‘optoelectrode’ probe is potential neuroscience-technology breakthrough

Scientists have developed a first-ever technique for using skin samples from older patients to create brain cells — without first rolling back the youthfulness clock in the cells. The new technique, which yields cells resembling those found in older people’s brains, will be a boon to scientists studying age-related diseases like Alzheimer’s and Parkinson’s.

“This lets us keep age-related signatures in the cells so that we can more easily… read more

A soft, bio-friendly ’3-D’ brain-implant electrode
