Peggy Whitson’s career as an astronaut has been trailblazing: With a total of 665 days in space, Whitson not only currently holds the space endurance record in the U.S., she is eighth on that list overall. She was the first woman astronaut to hold NASA’s chief astronaut position, has completed a total of 10 spacewalks over the course of her career, and commanded the International Space Station twice.

Music is the language of feelings, the food of the soul. But could it also be a grade booster for high school students? Researchers think so — if students engage in actually playing the music (not just listening to it).

A new study published in the Journal of Educational Psychology reports high school students who play musical instruments score significantly higher in science, math, and English exams than their non-musical peers. The authors …

Last week, NASA’s Mars Curiosity rover detected a sudden spike in methane levels, which kickstarted excitement about the prospects of life on the Red Planet.

On Earth, the most common source of methane is biological organisms, from cows and humans down to single-celled creatures, making its detection on the Red Planet a reason for excitement and intrigue. But it’s quite possibl …

Nanobacteria in the Brain?

By Neuroskeptic | June 23, 2019 5:49 am

A paper just out in eccentric medical journal Medical Hypotheses caught my eye yesterday:

Potential role of calcifying nanoparticles in the etiology of multiple sclerosis

Hmm, I thought, this looks interesting. I’d never heard of the idea that nanoparticles could cause neurological illness.

So I read the paper and quickly found myself falling down a (nano)rabbithole into a fascinating and little-known tale of strange science.

It turns out that the ‘calcifying nanoparticles’ ment …

Big Blast from Russian Volcano Raikoke

It has been awhile since we’ve had an unexpected eruption, but last night Raikoke in the Kuril Islands off Russia had an impressive explosion. Most people (and volcanologists) are likely unfamiliar with this remote volcano and rightly so — only ~140 people live within 100 kilometers and the last known eruption was in 1924. However, the last two eruptions (1924 and 1778) were both VEI 4 events.

The new eruption sent a  …

Meet the Companies Trying to Put Humans Back on the Moon

The rocket’s flare is sudden and brilliant, a blurring horizontal column of whooshing fire. Just as quickly, the bright jet flickers out of existence, the few seconds of burn enough complete the test.

A pause in the control room, then applause ripples around. The group retires to a test cell nearby, where there are speeches and p …

The sun powers life on Earth and keeps us from freezing to death. It also occasionally sends out bursts of charged particles that can be deadly to astronauts outside Earth’s sheltering atmosphere, and also wreak havoc on electronics both on and above Earth. There’s also a lot researchers still don’t understand about the sun’s behavior, including how its outermost layer get …
