Recent research has found that changes in the gut microbiota — the trillions of bacteria and other microbes that live in the intestines — can alter the brain and behavior. Now, a study led by scientists at UCLA could elucidate how and why that phenomenon occurs.

In the experiment, which was conducted with mice, researchers found that gut microbes can exacerbate the effects of cognitive impairment because of how they affect the hippocampus, the region of the brain that is critical for memory and learning...

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a soft and stretchable battery that is powered by human perspiration.

The prototype battery consists of printed silver flake electrodes that generate electricity in the presence of sweat. Measuring 2 cm by 2 cm and as flat as a small paper bandage, the battery is affixed to a flexible and sweat absorbent textile that is stretchable and attachable to wearable devices, like watches, wrist bands or arm straps.

To demonstrate its potential use when it becomes incorporated in wearable biosensors and other electronic devices, the team of scientists tested their device with artificial human sweat.

In a separate trial, the team reported that an individual wearing the battery around their wrist ...

Astronomers have published the most detailed images seen of galaxies beyond our own yet, revealing their inner workings in unprecedented detail.

The images were created from data collected by the Low Frequency Array (LOFAR), a network of more than 70,000 small antennae spread across nine European countries. The results come from the team’s years of work, led by Dr. Leah Morabito at Durham University. The team was supported in the UK by the Science and Technology Facilities Council (STFC).

As well as supporting science exploitation, STFC also fu...

Not everyone benefits equally from TRE, but TRE has important health benefits for all. Time-restricted eating (TRE), a dietary regimen that restricts eating to specific hours, has garnered increased attention in weight-loss circles. A new study by Salk scientists further shows that TRE confers multiple health benefits besides weight loss. The study also shows that these benefits may depend on sex and age.

Most TRE studies focus on weight loss in young male mice, but Salk scientists wanted to determine whether TRE confers additional benefits on other populations...
