Each year, the Long Beach Scuba Show brings together divers from around the world for seminars and exhibits on all things scuba, with topics ranging from dive gear to scuba vacations. Though the show mostly showcases the business side of diving, visitors can also learn about nonpro …

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 …

Ancient Campfire Remains Hold Oldest-Known Remains of Humans Cooking Starches

More than 100,000 years ago, humans lived in the caves that dot South Africa’s coastline. With the sea on their doorstep and the Cape’s rich diversity of plant life at their backs, these anatomically modern Homo sapiens flourished. Over several millennia, they collected shells that they used as beads, created toolkits to manufacture red pigment, and sculpted tools from bones.

Now some of these caves, along the country’s s …

In the past two decades, the monarch butterfly population east of the Rocky Mountains has declined by 87 percent. That’s due in part to the fact that the only plant that monarchs lay their eggs on – milkweed – has become scarcer thanks to farmers removing it from their fields. Scientists say that stopping the monarch’s decline will require planting some 1.8 billion stems of milkweed. And, according …

So, you just got a parking ticket. Let’s assume it wasn’t the first. And let’s take that a step further and say that you absolutely, positively, do not want to pay it, or think you should, for that matter.

Or let’s say you’re in a more serious situation – you’re planning
to file for divorce. You might not be able to afford an expensive attorney, or
maybe you just flat-out don’t know where to start with the legal process.

Thanks to a s …

Well, the results are in. After years and years of nutritionists telling Americans to eat fewer processed meats and more fish, Americans are eating (drumroll please) … exactly the same amounts as they did 18 years ago.

A research team at Tufts University in Boston crunched the numbers, and published their study today in the Journal of the Academy of N …
