People with inflammatory bowel disease (IBD) are often confused about which foods may ease symptoms and which ones may make them worse. Based on medical research, there’s no single plan that definitively offers relief. But a recent study on a new diet called the IBD-AID diet has shown that it may help.

The diet focuses on correcting gut bacteria balance with probiotic and prebiotic foods.

NASA is sending a pair of astronauts on a spacewalk outside the International Space Station today (Jan. 25) to finish fixing a complicated science experiment. Here’s how to watch it live.

NASA TV began streaming the spacewalk around 5:30 a.m. EST (1030 GMT) as European Space Agency astronaut Luca Parmitano and NASA astronaut Andrew Morgan complete their final spacewalk preparations. You can watch it live here on Space.com. The spacewalk is expected to start around 6:50 a.m. EST (1150 GMT), when the astronauts will switch their spacesuits over to battery power before heading out of the airlock.

When it comes to building the interior of a spacecraft, engineers often prioritize function over aesthetics, focusing on materials and hardware that are both safe and effective for executing the vehicle’s intended mission. But some scientists say it’s time to consider another crucial factor when designing a spacecraft’s insides: how it will affect the behavior of the passengers?

University of California, Berkeley, scientists have created a blue light-emitting diode (LED) from a trendy new semiconductor material, halide perovskite, overcoming a major barrier to employing these cheap, easy-to-make materials in electronic devices.

In the process, however, the researchers discovered a fundamental property of perovskites that may prove a barrier to their widespread use as solar cells and transistors.

Alternatively, this unique property may open up a whole new world for perovskites far beyond that of today’s standard semiconductors.

Early morning exposure to blue wavelength light can help heal the brain following mild traumatic brain injury (mTBI), new research suggests.

Results of a small, randomized controlled trial showed blue-light therapy improved brain structure and function, cognition, and sleep in this patient population.

“We found that blue-light therapy improved patients’ daytime sleepiness,” study investigator William D. ‘Scott’ Killgore, PhD, told Medscape Medical News. “So those who got the blue light were less sleepy 6 weeks later than they had been at baseline.”
