A phase 1 trial found that personalized neoantigen vaccines combined with PD-1 blockade were feasible in high-grade serous ovarian cancer and produced tumor-specific immune responses in many patients, with resistance …
Iowa State University researchers found that the mammary glands of several livestock species can harbor H5N1, calling for broader surveillance beyond dairy cattle to prevent undetected spread.
Karl Deisseroth, Peter Hegemann and Georg Nagel win the 2026 Nobel Prize in Physiology or Medicine for discoveries concerning light-gated ion channels and optogenetics, a technique that uses light to …
Researchers have developed a protective coating for mitochondria that maintains their energy-generating capacity, a step toward transplanting healthy mitochondria into damaged cells, though clinical effectiveness remains unproven.
A study of 52,236 patients with cancer has produced a multimodal atlas of cachexia, linking weight-loss episodes to systemic serologic signatures and specific tumor genotypes, and showing that the condition …
Researchers at Iowa State University have found that the mammary glands of several livestock species can harbor avian influenza, prompting calls for broader surveillance beyond dairy cattle.
A study from Oregon Health & Science University and Massachusetts General Hospital finds that people who eat late at night face a 20 to 30 percent higher risk of liver …
A new call in Nature argues that medical doctors working in academia need better career support and more stable funding to remain in research, warning that their departure would weaken …
A commission of 35 leaders warns that 17 interconnected threats could cost tens of billions of healthy life years by 2100, but targeted action can still prevent the worst outcomes.
Texas A&M researchers have found that polyethylene microplastics can contribute to fatty liver disease, with effects worsening when combined with an unhealthy diet. The plastic was previously considered relatively harmless.
A clinical trial found that adjusting foot angle during walking reduced knee osteoarthritis pain comparably to medication and slowed cartilage deterioration on MRI, offering a drug-free, surgery-free option.
Scientists have developed a seed-sized, injectable device that controls nerve activity wirelessly, without surgery, batteries, or wires, showing promise for chronic pain and movement disorders.
Researchers have identified a previously unknown cleanup system at the back of the eye that removes fluid and waste, a discovery in mice that could lead to new treatments for …
A correspondence in The Lancet warns that medical AI is advancing faster than regulation, ethics, and professional oversight can keep up, and calls for the order to be reversed so …
A correspondence in The Lancet argues that the NordICC trial's finding on colonoscopy screening should be interpreted in the context of four randomized trials covering more than 458,000 participants, which …
A commission of 35 leaders warns that interconnected threats—from obesity and climate change to nuclear conflict and malicious AI—could cost tens of billions of healthy years by 2100, but targeted …
A technique that uses a light-sensitive algal protein and modified viruses to make retinal cells respond to light has produced partial vision recovery in seven people, marking the first human …
Researchers find that chronic diabetic wounds persist because immune cells remain trapped in inflammatory states, blocking the transition to tissue repair, and suggest reprogramming these cells could lead to targeted …
Researchers analyzing brain scans from 263 people with depression found five separate profiles of neural communication, suggesting the condition may be several biological subtypes rather than a single disorder.
In the NEOPRISM-CRC trial, 32 patients with a specific genetic form of stage two or three bowel cancer received pembrolizumab before surgery instead of post-surgery chemotherapy. After nearly three years, …
