Vitamin D deficiency is associated with more moderate to severe pain following breast cancer surgery and an increased consumption of opioid drugs, finds research published online in the journal Regional Anesthesia & Pain Medicine.

Severe infections linked to opioid use often progress rapidly, particularly when access to timely medical care is limited. This can result in devastating health outcomes, including life-altering amputations.

AI-enabled research tools can accelerate health research, but their data-science roots may clash with epidemiological workflows built around prespecified designs, causal reasoning, bias control, and reproducibility. The article argues that researchers should integrate AI cautiously, using clear workflow boundaries, peer review of AI outputs, and sustained human accountability.

The most common white blood cells in your body - immune cells called neutrophils - can make a protein nobody knew they were making, Stanford Medicine investigators have discovered.

Researchers at Rutgers University-New Brunswick are working to measure pain more accurately beyond the single, subjective question patients are often asked: "On a scale of 1 to 10, how bad is your pain?"

This Communications Biology study used intracranial EEG in 22 epilepsy patients to map how the human brain processes new images of faces and places within milliseconds.. It found that visual information flows from the occipital cortex through parallel dorsal and ventral pathways toward frontal and limbic regions, with distinct timing patterns for faces and places.

Children who take more risks on the playground make safe decisions more quickly when crossing a busy street.

A new research paper was published in Volume 18 of Aging-US on May 5, 2026, titled "Methylene blue protects hair follicle stem cells from oxidative and metabolic stress to enhance hair regeneration."

A team of researchers from the Keck School of Medicine of USC, the USC Alfred E. Mann School of Pharmacy and Pharmaceutical Sciences and the USC Shaeffer Center for Health Policy & Economics have conducted a head-to-head comparison of five leading treatments for anaplastic lymphoma kinase-positive (ALK+) non-small cell lung cancer.

Researchers at the Francis Crick Institute have revealed that sensory nerve signals interfere with the immune system's response to lung cancer.

Congenital syphilis is entirely preventable-yet new research shows critical gaps in prenatal screening that are leaving some infants at risk.

An experimental diagnostic tool in the form of a computer game was able to quickly identify patients with depression based on anhedonia, a key feature of the disease, a new study shows.

Engineers from the University of Houston, MIT and Harvard have developed a new mRNA-based strategy that dramatically amplifies the T-cell response to vaccines - an advance that could lead to far more powerful cancer vaccines and stronger protection against infectious diseases.

Cigarette smoking is the leading preventable cause of death in the United States, even as rates of cigarette smoking have fallen to an all-time low of approximately 10% in 2024.

Tirzepatide GLP-1 medication is known to improve sleep apnea for people with both obstructive sleep apnea (OSA) and obesity, but not all patients benefit equally.

The causes of male infertility can be hard to diagnose, with many tests failing to detect genetic defects. Sometimes, infertility doesn't even involve the genes themselves.

A large new study presented at the 2026 ATS International Conference shows that patients treated for COPD or pneumonia experience worse outcomes across several important measures when they are treated at hospitals that have been acquired by private equity firms.

An estimated 15.8 million people in the United States live in pharmacy deserts. With limited access to healthcare services, like hospitals and pharmacies, these individuals are at risk of elevated mortality risk and higher rates of preventable disease progression.

A recent trial of community-based and nurse-led ultrasound screening for hip dysplasia in Japan has been met with great success, according to new research at the University of Tokyo.

Sexuality is an important part of life - even when we grow old. The idea that desire disappears with age is a myth that needs to be debunked, argues a psychologist who has researched older adults' sex lives.
