The electric vehicle is designed to shift to “reptilian” or “mammalian” walking mode when terrain turns tough.

A new device developed by Stanford University researchers could make it easier for doctors to monitor the success of blood vessel surgery. The sensor, detailed in a paper published Jan. 8 in Nature Biomedical Engineering, monitors the flow of blood through an artery. It is biodegradable, battery-free and wireless, so it is compact and doesn’t need to be removed and it can warn a patient’s doctor if there is a blockage.

“Measurement of blood flow is critical in many medical specialties, so a wireless biodegradable sensor could impact multiple fields including vascular, transplant, reconstructive and cardiac surgery,” said Paige Fox, assistant professor of surgery and co-senior author of the paper. “As we attempt to care for patients throughout the Bay Area, Central Valley, California and beyond, this is a technology that will allow us to extend our care without requiring face-to-face visits or tests.”

Monitoring the success of surgery on blood vessels is challenging as the first sign of trouble often comes too late. By that time, the patient often needs additional surgery that carries risks similar to the original procedure. This new sensor could let doctors keep tabs on a healing vessel from afar, creating opportunities for earlier interventions.

LG on Monday unveiled a roll-up television screen as a trend of bendable displays began taking shape at a consumer electronics extravaganza in Las Vegas.

People (including myself) love slow-motion videos and we also tend to love watching things being destroyed. Lawnmowers are really, really good at destroying things, but capturing its destructive power with a high-speed lens isn’t the easiest thing in the world… unless you flip it upside down and strap the camera right to the blade.

Now, I wouldn’t want to be the one to tackle such a project, but the good news is that a YouTuber by the name of Tesla500 has already done all the hard work. The over 20-minute-long video shows the building of the rig itself as well as lots and lots of random household objects meeting their end in super slow motion.

To save power, a cheap new timer can tell smart sensors when to wake up—no batteries required.

It’s a whole new look at electrons.

Implanted electronics are typically large, require batteries, and sometimes need replacement—but new technology could change that.

Some of the devices even dissolve in the body once their work is done.
