The genome of the immortal jellyfish has been sequenced

The genome of the immortal jellyfish has been sequenced

By The immortal jellyfish is, true to its name, biologically immortal, capable of to perpetually begin again. When the jellies’ adult forms — called medusa — are stressed, injured, or otherwise in an unideal situation, they revert back to an earlier stage of their life cycle, becoming a film of cells that looks for a place to anchor and develop into a polyp.From there, new medusae bud off of it, allowing the immortal jellyfish to reproduce asexually and be reborn. And unlike most other jellies that have reset abilities limited to before becoming sexually mature, the immortal jellyfish...

Researchers are fighting to clear brain fog

Researchers are fighting to clear brain fog

By Brain fog: It’s likely you’ve felt it, or someone you know has. I’ve certainly felt it — that kind of cobwebby cognition, like focusing through a broken camera lens, where memory feels like sand through your hands. Like you didn’t sleep a wink, even when you have; like allergy meds or a couple drinks, without the pills or libations.People call this amorphous set of not-quite-right feelings brain fog, and it has become one of the signature symptoms of . Long COVID: Long-term problems caused by infections are called sequelae, and they have been a known complication of viral...

New solar device can pull hydrogen straight from the air

New solar device can pull hydrogen straight from the air

Hydrogen fuel is an attractive candidate for a clean energy source, since it burns very clean. But on Earth, hydrogen is almost always bound up with other elements, and separating it requires a ton of energy. Almost all hydrogen today is created with .The main alternative to this process uses electricity, which is often generated via fossil fuels, thereby defeating the purpose, and clean water, also a precious resource.But researchers with the University of Melbourne and University of Manchester have developed a way to harness solar power and the very air around us to produce truly...

Jeremy, 47, is a political writer in Washington, DC who spends his spare time writing screenplays and producing what he calls “nerd punk rap” music.

Why a third of antidepressants are prescribed for "off-label" problems

It was when he became a father that Michael Briggs resolved to somehow bring his ulcerative colitis under control. He was determined to avoid what many people with the disease end up needing – having part or all of their large intestine removed. A trained scientist, manager of a physics lab at the University of New Hampshire, he began reading medical research papers, looking for anything that might help him.He knew there wouldn’t be just one single cure, just as he knew there was not one single cause behind this inflammatory bowel disease (IBD), which causes gut pain, bleeding and...

Newly discovered antibody neutralizes all variants of the coronavirus

Newly discovered antibody neutralizes all variants of the coronavirus

By Researchers at Boston Children’s Hospital and the Duke University School of Medicine have identified a new COVID-19 antibody that is capable of neutralizing every known variant of the coronavirus.Key to its potential is that, although the new antibody attacks the virus’ notorious spike protein, it does so in a way different from other antibodies.“SP1-77 binds the spike protein at a site that so far has not been mutated in any variant, and it neutralizes these variants by a novel mechanism,” Boston Children’s Tomas Kirchhausen . “These properties may contribute to its broad and...
