CVS and Walgreens limit COVID vaccines in some states as rules shift

Breast cancer is the most common cancer in women worldwide. In sub-Saharan Africa, it is a leading cause of cancer-related deaths among women.

A Korean research team has reported that artificial intelligence (AI) used in mammography missed 14% of invasive breast cancers, the type where delayed diagnosis can directly impact patient survival.

Celebrity chef and restaurateur Gordon Ramsay revealed he had surgery to remove basal cell carcinoma, a common form of skin cancer, from his jawline.

Researchers at Tsukuba University in Japan report that memories acquired while awake are stored in a more permanent form (called memory consolidation) during the REM stage of sleep, and that this process requires the reactivation of only a few specialized neurons involved in memory formation. They found that three of these neurons are crucial for memory consolidation during REM sleep.

A multinational collaboration of researchers report that psychiatric spousal resemblance across nine psychiatric disorders appears consistent and persists across birth cohorts for roughly 90 years in a sample of over 14 million.

Scientific breakthroughs often emerge from unexpected and unlikely places. The development of penicillin was an accident, Velcro was inspired by plant burrs and multiple cancer treatments have been developed from sea sponges.

Scientists at Ben-Gurion University of the Negev have discovered that human cells operate a sophisticated, synchronized traffic control system that actively monitors nutrient availability and precisely controls cellular energy balance and blood sugar levels. This finding challenges long-held assumptions about how cells sense and respond to changing nutrient levels—and offers a promising new target for treating diabetes and cancer.

The use of assisted reproductive technologies like in vitro fertilization is becoming more common worldwide. However, while these technologies successfully create viable embryos, a little over half of all embryos are lost because they fail to implant into the uterus.

Inflammation in the brain is usually seen as harmful in the aging process—it's thought to contribute to Alzheimer's and dementia. But a new study in mice suggests that inflammation, led by an immune molecule called STING (stimulator of interferon genes), might have a role in protecting the aging brain. The findings also have implications for new experimental Alzheimer's drugs that are designed to block STING.

The human body is a complex and interconnected system, where alterations caused by one disease can promote the onset of others. This tendency for certain diseases to occur together, beyond what would be expected by chance, is called co-occurrence. Thus, although there are diseases with widely known co-occurrence in certain groups of patients, such as Crohn's disease and the development of ulcers, many of the molecular mechanisms that would explain them were, until now, unknown.

Researchers at Karolinska Institutet have identified a vulnerability in certain blood cancer cells that makes it possible to eliminate the cancer cells with a drug, without harming healthy cells. The study is published in Leukemia.

Scientists at the University of Leicester are hoping the collection of poo from tigers, elephants, giraffes and other exotic animals could contain the secret to finding new medical treatments.

Mass gatherings, such as major sports events and festivals, bring together people from different regions and countries. One associated risk of such large gatherings is the potential spread of antimicrobial resistance (AMR), a growing threat that undermines the effectiveness of treatments for infectious diseases.

Scientists from Trinity College Dublin have discovered that electrically stimulating macrophages—one of the immune systems key players—can reprogram them in such a way as to reduce inflammation and encourage faster, more effective healing in disease and injury.

A new evidence review undertaken by Swansea University academics to better understand the menopause-related experiences and needs of autistic people, has revealed significant gaps in knowledge, support, and health care provision, and identifies a need for targeted resources and interventions.

An international research team led by MDI Biological Laboratory President Hermann Haller, M.D. and postdoctoral researcher Yannic Becker, Ph.D. has discovered that a little-known molecule, heparanase 2 (Hpa2), plays a critical role in maintaining blood vessels' integrity.

An artificial intelligence tool which quickly analyzes brain scans of stroke patients has helped boost chances of full recovery since being launched across England, the public health service said on Tuesday.

Vericiguat did not reduce the risk of cardiovascular mortality and heart failure (HF) hospitalizations in ambulatory patients with HF and reduced ejection fraction (HFrEF) without recent worsening, according to late-breaking research presented August 30 in a Hot Line session at ESC Congress 2025. The research was published earlier this year in the European Journal of Heart Failure.
