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.
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.
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).
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.
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
