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.
A Lewis County child’s death became New York’s first known measles associated fatality in more than 30 years, intensifying concern as officials respond to 178 cases with emergency measures, vaccination efforts and expanded public health resources.
A six month trial found that intensive calorie restriction and supervised exercise dramatically increased type 2 diabetes remission among younger adults, while helping participants lose weight, preserve muscle and improve cardiovascular fitness.
UCLA researchers found that briefly increasing p53 activity with navtemadlin helped prepared human T cells resist exhaustion and kill more melanoma cells in laboratory tests, though animal studies and careful dose research are needed before clinical trials.
Florida has confirmed 485 locally acquired dengue cases, with roughly 95% concentrated around Tampa Bay. Emergency declarations, expanded spraying and intensified surveillance are underway as officials urge residents to eliminate standing water and prevent mosquito bites.
Research involving more than 6,000 postmenopausal women found higher cardiovascular event rates among testosterone users, but its observational design cannot prove causation. Experts urge careful risk assessment, dosing and monitoring when considering treatment.
A South Korean assessment found paper straws scored 6.33 times worse than conventional plastic on one modeled pollution measure, while researchers cautioned that the result does not show drinking through paper straws increases cancer risk.
Iron deficiency can cause fatigue, brain fog and other symptoms without anemia, while routine screening may miss many cases. Experts recommend ferritin testing rather than relying on viral claims that facial appearance can reveal low iron.
The Vera C. Rubin Observatory has detected ED138, a large object beyond Pluto that may qualify as a dwarf planet. Astronomers now need further observations to determine its size, classification and physical characteristics.
Magnetic TESSERAE tiles could autonomously assemble large structures after launch, offering a potential path toward adaptable habitats, antennas, solar arrays and data centers while reducing the constraints imposed by limited cargo space inside rockets.
Researchers tracking more than 4,000 older adults found that faster everyday walking was associated with a lower risk of death, although experts cautioned that the findings do not prove increasing pace will extend a person’s life.
Agatha Christie’s pharmacy training transformed poisons into a powerful literary weapon. Her scientifically accurate mysteries did more than captivate readers, with details from “The Pale Horse” later helping people recognize two cases of thallium poisoning.
Computer simulations suggest early comets usually struck Earth too fast for hydrogen cyanide to survive, weakening a theory dating to at least 1961 while leaving asteroids, primordial chemistry and ancient Mars open for further study.
Researchers adjusted for brain donation bias and estimated that about 3 in 4 former NFL players who died from 2008 through 2023 had CTE, while experts cautioned that the disease does not always cause symptoms.
The FDA is proposing new requirements for four essential infant formula nutrients, beginning a broader review that will eventually examine all required nutrients, possible additions and carbohydrate sources, though consumers may not see changes for several years.
