Using the James Webb Space Telescope (JWST), astronomers from Canada and Switzerland have discovered a new galaxy, which received designation COSMOS2020-635829. The newfound object appears to undergo a ram pressure stripping of gas and therefore may be a "jellyfish" galaxy. The finding was detailed in a research paper published June 17 on the arXiv pre-print server.

#SkinnyTok is dead. Or at least that's what TikTok wants you to believe after its recent ban of the hashtag promoting an extreme thin ideal.

Hackers infiltrated one grocery distributor, and within days, there were bare shelves at stores around the country and even some pharmacies unable to fill prescriptions. That's not the beginning of some thriller novel. It's the real events that played out earlier this month as major wholesale distributor, UNFI, dealt with a cyberattack. But the moral of the story is already clear: the nation's highly consolidated food supply is in need of stout digital defenses to protect it.

Boston Children's Hospital scientists have unveiled a five-day approach to generate functional vascular organoids capable of supporting blood flow and in vivo engraftment. Blood vessels are the living conduits that deliver nutrients and oxygen throughout the body, regulate hemostasis, and modulate inflammation. During development, vasculature shapes organ formation and supports postnatal tissue growth and repair, while vascular niches maintain stem cell populations.

Dozens of HIV experts at the Centers for Disease Control and Prevention received emails earlier in June revoking notices they received 10 weeks ago that laid them off. Damage to their projects may be permanent, however, and ongoing restrictions on their research will harm lives, multiple HIV scientists at the CDC told KFF Health News on condition of anonymity because of fears of retaliation.

Brain death determination sits at the fraught intersection of critical-care medicine, ethics, and organ-donation logistics. Missteps risk either prolonging mechanical support with no prospect of recovery or declaring death in error—a prospect that evokes the terrors of many Edgar Allan Poe writings.
