Rare gene mutation raises lung cancer risk 60-fold in nonsmokers, study finds

A rare inherited mutation in the EGFR gene is associated with a 25-fold increased risk of lung cancer — and among people who have never smoked, the risk jumps to more than 60-fold — according to a study published Thursday…

Neuralink demo shows brain implant restoring speech to impaired user

Neuralink shared a video on September 16 showing a clinical trial participant with speech impairment using the company's N1 brain implant to communicate the words "I love you" to a loved one — using thought alone. Elon Musk called the…

Cambridge scientists find protein that predicts preeclampsia in first trimester

Researchers at the University of Cambridge have identified a protein that serves as a first-trimester predictor of preeclampsia and fetal growth restriction, a discovery that could lead to new screening tests and treatments for two of pregnancy's most dangerous complications.

Study finds Alzheimer’s brain changes 7 years before plaques appear

Alzheimer's disease may leave detectable traces in the brain more than seven years before amyloid plaques — long considered the earliest measurable sign of the condition — become visible on PET scans, according to a study published this week in…

AI ’tissue clocks’ can estimate biological age of individual organs

Researchers have built artificial intelligence systems that can estimate how old individual human organs are biologically by reading microscopic patterns invisible to the naked eye, offering a new way to track aging and disease that may eventually require nothing more…

Triple-drug regimen clears HIV in newborn primates, OHSU study finds

A one-time combination of three therapies administered within 72 hours of birth permanently cleared HIV infection in newborn primates, according to a study published in Nature Microbiology by researchers at Oregon Health & Science University. The findings, announced on August…

Scientists reconstruct first complete genome of a living person

Scientists have reconstructed the complete genome of a living person for the first time, capturing full sets of chromosomes from each parent in a achievement that researchers say will make personalized genomics routine in medical care. The advance, published Thursday…

Stanford study finds blocking one receptor slows aging in mice

A study published in the journal Science on Wednesday reveals that blocking a single receptor on immune cells can restore the body's ability to clear senescent "zombie" cells, preventing cognitive decline, frailty, and weight gain in aging mice. The research,…

Scientists find 81 hidden genes driving deadly breast cancer

A team of scientists at Sinai Health in Toronto has uncovered 81 previously unknown genes involved in basal-like triple-negative breast cancer, solving a long-standing mystery of how chromosomal chaos fuels one of the disease's deadliest forms. The findings, published in…

China’s RNA editing therapy treats muscular dystrophy in global first

A research team from Changping Laboratory and Peking University has published results in the journal Cell showing that a China-developed RNA editing platform successfully treated pediatric patients with Duchenne muscular dystrophy, marking the first clinical application of RNA editing for…
