The American Cancer Society now recommends clearer PSA screening schedules, with earlier annual testing for Black men and certain men with a family history, following stronger evidence that screening can reduce prostate cancer deaths.
A boy, 15, needed emergency treatment after drinking a beverage containing cod collagen, even though skin prick tests for several fish allergies were negative. Experts say fish derived proteins in drinks and supplements demand close label scrutiny.
Sunharbo reduced ischemic stroke risk by 26% in a phase 3 trial, but bleeding concerns affected some patients. Cardiologist Richard Kovacs says treatment discussions should begin soon after a qualifying stroke because trial participants received the drug within 72 hours.
Stone weapons carrying plant residues and possible poison compounds reveal how early humans used complex hunting strategies to survive beside an Arabian desert lake 125,000 years ago.
Two dramatic periods of mountain growth roughly aligned with biological diversification and major oxidation events, leading researchers to propose that erosion from taller ranges supplied oceans with nutrients essential for increasingly complex life.
An international expert commission has withdrawn the nation’s measles elimination status as sustained outbreaks, falling vaccination levels and more than 5,400 reported cases expose a severe reversal in decades of US public health progress.
A Stanford analysis found that metformin users with type 2 diabetes had a 39% lower risk of death after COVID-19, but researchers cautioned that patient differences and the study design prevent proof of a direct protective effect.
A study of 2,495 older adults in Ireland found no association between estimated lifetime exposure to fluoridated household water and cognitive performance, though researchers said continued monitoring and future studies remain important.
The American Cancer Society now recommends regular PSA testing from age 50 for average risk men and from 45 for Black men and those with strong family histories, citing stronger evidence that screening can reduce prostate cancer deaths.
Researchers examining Levantine archaeological sites suggest that colorful stones, crystals, fossils, and weathered tools became prehistoric keepsakes, possibly helping ancient hominins preserve memories, recognize meaningful landscapes, and eventually develop mechanisms supporting autobiographical memory.
NASA is inviting people worldwide to flash Voyager 1’s call sign toward the sky as the spacecraft becomes the first human made object to reach one light-day from Earth on November 18, 2026.
November’s sky will feature the remarkably fast Leonid meteor shower, a full Moon appearing up to 14% larger, several visible planets, and the Hera mission’s arrival at asteroid Didymos and its moon Dimorphos.
Experts expect the US to lose measles elimination status as outbreaks surge and vaccination rates decline, but proven vaccines, stronger leadership, and carefully designed public health strategies could help the country interrupt transmission again.
The nearby Type Ia supernova SN 2026ahvu is approaching peak brightness, offering professional and amateur astronomers a valuable chance to track an explosion that could refine scientific understanding of crucial cosmic distance markers.
Laboratory experiments found that healthy corals can fuse with bleached members of the same genet, transferring algae that drive rapid recovery. Researchers are now investigating ways to reproduce that rescue without requiring direct coral contact.
After its original type specimens vanished, Araneus angulatus, the first officially named animal, has a new physical reference. Scientists selected an adult male collected near the historic Swedish locality and published the designation in Taxonomy.
Genetic evidence from 86 howler monkeys revealed two previously unrecognized Amazonian species and challenged existing classifications, giving scientists a clearer picture of the primates’ evolution while strengthening calls to protect threatened habitats and vulnerable populations.
