The ear-EEG utilizes integrated electrodes to measure tiny voltage changes on the skin in the ear canal, which correspond to the electrical activity of the brain

EEG earbud is made to monitor astronauts' sleep patterns on the ISS

Sleeping while wired up with an EEG cap would be hard enough here on Earth, but can you imagine trying to do so in the zero-gravity environment of outer space? It could be quite awkward, which is why an earbud has been designed to do the same job.

Researchers have found a promising natural lubricant excreted in the knee joints of darkling beetles

Natural beetle juice outperforms Teflon as a lubricant

No matter what humans come up with, chances are nature has already done a better job. Now researchers have discovered the latest example – beetles naturally lubricate their knees with a strange substance that works better than Teflon.

Autonomous underwater vehicle looks for algae on underside of ice

Every spring in Antarctica, mats of algae form on the underside of the sea ice. These mats serve as a food source for zooplankton, essentially kickstarting the food chain for the year. Scientists have set out to better understand the algae's distribution, using a high-tech underwater drone.

Flat running shoes fine for pronating novices, study finds

Novice runners wearing ordinary, non-supportive running shoes are at no greater risk of injury, even if they pronate or supinate (that is, their feet roll inward or outward as they run) according to new research out of Aarhus University in Denmark.
