If we tried to, we’d simply be unwell. Here’s the good news. This mushy brain sensation probably isn’t merely in our heads. And this might be the human body’s way of protecting itself from burnout. The first group was given difficult cognitive tasks, like those involving stressful economic-related decisions. To confirm one way or another, further testing is required. OK, so what’s the solution, you ask? There is good evidence that glutamate is eliminated from synapses during sleep....

Now, scientists have finished sequencing the other 8%, and thehuman genome has finally been fully sequenced. “95% of the puzzle being solved is good enough for some people. Even with this accomplishment, more work – and deeper understanding – lies ahead.

Studying dark matter is complicated. In reality, the best way to think about the phenomenon is astransparentmatter. But scientists haven’t backed down from the challenge. So, where does dark matter tie in? But the shape of the lights reveals the shape of the tree. It is the same with stellar streams – their orbits reveal the dark matter."

This is the first time, it is believed, that objective data has been collected from dreams. Except it’s a little more complicated than that. The process was repeated nearly 200 times for each subject over the course of 10 days. The full results of the study can be seen, behind a pay wall, inSciencemagazine.

The secret is in the materials that burn. Combining the rare-earth metal ytterbium with copper created a shower of long sparks that turned from gold to green. The American Chemical Society (ACS) released a video on Wednesday showing the sparkler experiments in action. The team published itsresults in the American Chemical Society journal ACS Omegain August. The researchers also experimented with creating eye-catching fountains. The striking sparklers won’t be found at fireworks stands anytime soon....

“Mother Nature doesn’t usually offer up such convenient and life-long records of an individual’s life.” This woolly one didn’t exactly have an easy journey, though. That fate was a sad harbinger for the entire species.

But the 2 million blocks that make up the tomb and fortress have not been impenetrable. This is how the team was able to first discover the North Face Corridor and then characterize its features. The corridor itself islikely27 feet in length and pipe-shaped and runs horizontal to the ground. Why hide these chevrons? What were they for? Why is there a corridor behind them?

How the parasite accomplishes this is still a mystery. But eventually, the tarantula will die, according to the university. What does any of this have to do with actor known for roles inThe NewsroomandDumb and Dumber? It’s a references to his 1990 horror-comedy filmArachnophobia. The newly named parasite is a nematode. The findings were published Monday in theJournal of Parasitology. Daniels said in a statement that he is honored.

“Small one bites you, don’t keep it to yourself.” Turns out Indy knew his stuff. Thepaper published in the journal Toxinsin March looked at 36 species of scorpions. Venomous creatures The most potent scorpions had smaller bodies, but also smaller pincers. Understanding the connection between scorpion size and venom potency can help with medical treatments.

As anyone with a cat can tell you, felines don’t surrender their secrets easily. The tabbys have made their mark on pop culture, too. Morris the 9Lives cat food mascot is an orange tabby, as are cartoon cats Garfield and Heathcliff. Seemingly identical cat-skin cells can acquire different genetic signatures that later result in the cat’s intricate fur patterns. The same could hold true for large wild cats, such as leopards and tigers....

The path to the Emerald City might travel along the ocean’s bottom. The feature resembles a road paved in cobblestones. Nautilus spent most of April studying the geology and biological systems of seamounts, underwater mountains with volcanic origins. The brick-like patterns likely come from heating and cooling cycles connected to eruptions.

To some they’re charming, to others they’re creepy. (And no, it’s most certainlynot capable of killing you.) Now scientists have done something with one species of the house-dwelling spider you’ve certainly never seen before. They’ve created “daddy short legs” specimens by tweaking the creatures' genes. Thestudy is publishedin the latest issue of the journal Proceedings of the Royal Society B. The research team hopes the work will facilitate the development of more sophisticated tools for functional genetics....

Hydrasare tiny organisms related to jellyfish. Chop off a hydra’s head and it just grows right back. It finds that hydras use sequences of DNA called “enhancers” that regulate regeneration on the genetic level.
