Natural killer cells act as the immune system's rapid-response team, but the stress of anxiety and insomnia may be quietly thinning their ranks. A study of young women in Saudi Arabia found that both conditions were linked to significantly fewer NK . ...

Hot Jupiters were once cosmic oddities, but unraveling how they moved so close to their stars has remained a stubborn mystery. Scientists have long debated whether these giants were violently flung inward or peacefully drifted through their birth ...

Researchers in Sweden have unveiled a way to create high-performance electronic electrodes using nothing more than visible light and specially designed water-soluble monomers. This gentle, chemical-free approach lets conductive plastics form directly ...

Scientists have discovered that key compounds from cannabis--CBD and THC--show surprisingly strong effects against ovarian cancer cells. Used together, they slow cell growth, reduce colony formation, and may even block the cancer's ability to spread. ...

Back pain is wrapped in persistent myths, but many are far from the truth. From misconceptions about heavy lifting and bed rest to confusion over posture, exercise, and surgery, Dr. Meghan Murphy breaks down what really causes pain and what actually ...

SereNeuro Therapeutics revealed promising results for SN101, a first-in-class iPSC-derived therapy designed to treat chronic osteoarthritis pain while protecting joint tissue. Instead of blocking pain pathways, SN101 uses lab-grown nociceptors that . ...

Researchers discovered that tanning beds cause widespread, mutation-laden DNA damage across almost all skin, explaining the sharply increased melanoma risk. Single-cell genomic analysis revealed dangerous mutations even in sun-protected regions. ...

The study reveals how Balanophora plants function despite abandoning photosynthesis and, in some species, sexual reproduction. Their plastid genomes shrank dramatically in a shared ancestor, yet the plastids remain vital. Asexual reproduction appears ...

Scientists are uncovering a new possibility behind long COVID's stubborn symptoms: hidden infections that awaken or emerge alongside SARS-CoV-2. Evidence is mounting that viruses like Epstein-Barr and even latent tuberculosis may flare up when COVID ...

Scientists found that certain molecules made by gut bacteria travel to the liver and help control how the body uses energy. These molecules change depending on diet, genetics, and shifts in the microbiome. Some even improved insulin response in liver ...
