A sound technique for detecting knee osteoarthritis

Whether from a personal trainer, doctor, or purveyor of miracle-berries you met at the local farmer's market, you've probably heard the phrase, "listen to your body." UK researchers have developed a new technique for detecting knee arthritis that takes this idea literally, using sound waves to reveal the health of a person's knee. Read More

What "Star Wars" laser bolts would actually look like

It's no secret that Star Wars is full of scenes that defy the laws of physics. From space battles inspired by WW I and II dogfights to beams of light clashing in lightsaber duels. The laser bolts fired from Han Solo's trusty blaster and Luke's X-wing also play by their own rules, traveling much slower than the speed of light and being perfectly visible in the vacuum of space. Researchers in Poland have now created a film to show what a laser bolt would actually look like.Read More

Two-dimensional piezoelectric material forms basis of world's thinnest electric generator

Researchers from Columbia University and the Georgia Institute of Technology are laying claim to having observed piezoelectricity in an atomically thin material for the first time. The effect was demonstrated in the world's thinnest electric generator made from a two-dimensional molybdenum disulfide (MoS2) material, which had previously been predicted to exhibit such properties.Read More

Surgical robot takes a cheeky approach to brain surgery

Conventional open surgery on the brain involves drilling openings in the skull through which to access the gray matter. But what if the part of the brain needing to be accessed is located at the bottom of the brain as is the case with treating severe epileptic seizures? Generally it means more drilling. Now engineers at Vanderbilt University have developed a surgical robot that uses an alternative point of entry – the cheek.Read More

"Smart" lithium-ion battery would warn users if it is going to ignite

There have been numerous cases of lithium-ion batteries catching fire in everything from mobile phones and laptops to cars and airplanes. While the odds of this occurring are low, the fact that hundreds of millions of lithium-ion batteries are produced and sold every year means the risk is still very real. Researchers at Stanford University have now developed a "smart" lithium-ion battery that would provide users with a warning if it is overheating and likely to burst into flames.Read More

Surface coating for medical devices prevents blood clotting and bacterial infections

Our bodies have evolved to be pretty good at dealing with incursions by foreign objects and bacteria. Usually, that's a positive thing, but it can spell trouble for medical devices, such as replacement joints, cardiac implants and dialysis machines, which increase the risk of blood clots and bacterial infection. Now researchers at Harvard University have developed a surface coating that smooths the way for medical devices to do their job inside the human body. Read More
