Scientists pinpoint where in the brain we process facial expressions

Recognizing facial expressions is something that we do naturally, without any thought. However, whenever we smile or frown, or express any number of emotions using our faces, we move a large number of muscles in a complex manner. While we're not conscious of it, when you're looking at someone making a facial expression, there's a whole part of our brains that deals with decoding the information conveyed by those muscles. Now, researchers at the Ohio State University have worked to pinpoint exactly where in the brain that processing occurs. Read More


Precise embroidered circuits bring next-gen smart clothing closer to reality

From sweat-sensing wristbands to electrode-embedded workout suits, new innovations in smart clothing are coming thick and fast. Now, Ohio State University researchers have made another big breakthrough, managing to create embroidered circuits using metallic thread that's just 0.1 mm thick. By embedding different patterns, the tech could be used to create everything from a t-shirt that boosts your cellphone signal, to a hat that tracks brain activity.Read More


Bypassing spinal cord lets paralyzed man control own hand

Using a specialized sleeve, his own mind and a brain-implant smaller than a pea, a man paralyzed from the neck down has regained the ability to handle a variety of everyday objects. The researchers say the success of the technology, which bypasses the injured spinal cord, offers "realistic hope" to others with similar disabilities, with the team planning to expand the trial to include new patients in the coming months.Read More


Random vibrations turn tiny trees into power plants

Step aside windmills, there's a new way to harvest kinetic energy in the works. A research team at the Ohio State University has created electromechanical devices that look like tiny leafless trees and can generate electricity when they are moved by seismic activity, the slight swaying movements of a tall building, or the vibrations from traffic on a bridge.Read More


Researchers develop new energy-efficient technique to weld steel and aluminum

As manufacturers, particularly in the automobile industry, continue to work toward incorporating lighter metals like aluminum with heavier steel, the ongoing problem has been how to successfully weld them together. The problem is that the high heat created in the welding process actually weakens these lighter metals, creating a less than optimum weld. After 10 years of research, engineers at The Ohio State University have developed a new welding technique that may prove to solve this problem while also using 80 percent less energy and creating bonds that are 50 percent stronger.

Brain model with maturity of 5-week-old fetus grown in a lab

Researchers at Ohio State University (OSU) have grown a nearly complete human brain equivalent in size and structure to that of a five-week old fetus. Called a "brain organoid," it was bioengineered using adult human skin cells and is the most advanced human brain model yet created in a laboratory.Read More


The brain stores memories relative to time and place of origin

Where and when you form new memories affects where they are stored in the brain's hippocampus, which is the memory center in our brain, researchers at Ohio State University found in a new study. They saw evidence that a particular part of the hippocampus stores memories relative to time over durations of at least a month and space over distances of up to 30 km (18.6 mi).Read More


World's first "aqueous solar flow battery" outperforms traditional lithium-iodine batteries

The scientists that revealed the "world's first solar battery" last year are now, following some modifications, reporting its first significant performance milestone. The device essentially fits a battery and solar cell into the one package, and has now been tested against traditional lithium-iodine batteries, over which the researchers are claiming energy savings of 20 percent.Read More

Smartphones could run 30 percent longer, by harvesting their own radio waves

Scientists have already devised systems that allow electronic devices to scavenge power from ambient electromagnetic energy sources such as radio waves. While the technology has generally been limited to small devices such as wireless sensors, a research team has recently created a scavenging system that charges a smartphone's battery, letting it last up to 30 percent longer per charge – and the system does so using radio signals emanating from the phone itself.Read More
