A nationwide Icelandic study found that 6.9% of women aged 18-69 reported trauma-associated sleep disturbances in the past month. These symptoms were most common after sexual or physical violence, recent or repeated trauma, and were strongly linked to PTSD, anxiety, depression, and general sleep problems.

Ancient DNA from 46 Lake Baikal hunter-gatherers revealed two early plague outbreak phases about 5,500 years ago, with Yersinia pestis detected in 18 individuals. The findings suggest these basal plague strains caused lethal, child-heavy outbreaks long before dense farming societies, cities, or classical flea-borne bubonic plague emerged.

MIRA, an autonomous AI agent tested in a sandboxed electronic health record, diagnosed 574 real emergency department cases with 88.9% accuracy and outperformed physicians in a matched 311-case comparison. The system ordered tests, generated medication plans, and made admission decisions in simulation, but the authors stress that prospective validation, governance, and physician oversight are still essential.

A new study led by researchers at The University of Texas at El Paso found that use of weight loss drugs like Ozempic and other GLP-1s is associated with a lower risk of developing alcohol, opioid, nicotine and cocaine use disorders.

Researchers created a DIA-MS atlas of 13,609 proteins across 2,856 samples from fetal, healthy adult, paired non-tumor, and tumor tissues. The resource maps tissue-specific protein patterns, cancer-associated changes, organ-specific drug-toxicity signals, and candidate therapeutic targets.

Global health policymakers should focus on the way entire healthcare systems work together - improving one element does not always create better outcomes if the wider system is not ready.

Creatine, the organic acid that is popularly taken as a supplement by athletes and bodybuilders, supercharges a critical class of immune cells that activate and prepare the body’s key cancer-fighters, according to new UCLA research.

An international survey has highlighted major gaps in cardio-oncology training, despite its increasing clinical importance. These results were presented at ESC Cardio-Oncology 2026, the second annual conference of the European Society of Cardiology's Council of Cardio-Oncology.

Nearly half of Americans with kidney failure who are referred for transplantation never begin the process required to be considered for a new organ, a new study shows, while less than a fifth actually complete the assessment and get on the waitlist.

A natural quasi-experiment in Suba, Bogotá, found that more stringent COVID-19 mobility restrictions were associated with larger reductions in PM₁₀ and PM₂.₅ air pollution. The findings suggest targeted traffic and emissions controls could improve urban air quality, although ozone responses were more complex, and the results may not generalize beyond this high-traffic district.

Google’s AMIE research AI matched primary care physicians overall in simulated, multi-visit disease-management reasoning and scored higher on several measures of plan appropriateness, treatment precision, investigation precision, and guideline alignment. The study highlights the promise of conversational AI for longitudinal care, while emphasizing that AMIE is not ready for clinical use and still needs prospective real-world testing.

Synthetic microbial communities give researchers controlled models for testing how diet reshapes gut microbial ecology, metabolism, and host-relevant responses. The review highlights how SynComs can strengthen causal inference, improve intervention testing, and support future precision nutrition, while noting major challenges in stability, standardization, and ecological realism.

A new Review reveals how aging can push the immune system into a paradoxical state, weaker against threats yet more prone to attacking the body’s own tissues.

When H5N1 bird flu first began infecting U.S. cattle in early 2024, diagnosis was elusive, because in cows, the disease looked completely different.

The cardioprotective effects of heart failure treatments in patients with cancer were demonstrated today in a presentation at ESC Cardio-Oncology 2026, the annual conference of the European Society of Cardiology's Council of Cardio-Oncology.

An epigenetic "mechanostat" has been discovered that protects tooth-forming progenitor cells from mechanical stress and supports lifelong tissue renewal.

A new study published in JMIR Serious Games suggests that some video games may do more than entertain-they may also help adults cope with loneliness and build emotional resilience.

A new gene therapy has been used to successfully treat a deadly childhood liver disease using mice that model this disease by researchers at UCL and Great Ormond Street Hospital.

The Milken Institute Science Philanthropy Accelerator for Research and Collaboration (SPARC), in partnership with the Ann Theodore Foundation (ATF), today announced that the Ann Theodore Foundation Learning Opportunities in Medicine and Sarcoidosis (ATF-LOMAS) grant program has committed its first cycle of funding, totaling US$600,000 to early-career faculty conducting biomedical research in sarcoidosis.

Nearly all Michiganders age 50 and over say it's very important to keep their brains healthy as they grow older, a new poll finds.
