An analysis of more than 42,000 U.S. deaths linked to multiple sclerosis (MS) found that death rates varied by age, geography, and race and ethnicity, with Black patients dying younger than white patients and high blood pressure emerging as a growing contributor.

Researchers tested 18 stuffed toys and found that all released at least one targeted PFAS into artificial saliva under mouthing-relevant conditions, with PFHxA driving much of the variation between products. Modeled intake of the four PFAS covered by EFSA’s group tolerable weekly intake remained below that benchmark, but some high-PFHxA toys had reduced margins of exposure, and water rinsing produced mixed results.

New research has found a hormone is responsible for making mothers' interactions with newborns feel rewarding rather than just necessary.

Enhancers are pieces of DNA that act like switches, regulating when genes are turned on and off and how strongly they are activated.

Many people assume that some memory decline is an inevitable consequence of getting older. But a select group of older adults, known as SuperAgers, reach their 80s and 90s while retaining memory performance as good as or better than people in their 50s and 60s.

Exercise finds improvements in pain and function may fall short of what patients would notice in daily life, but more studies are needed to make firm conclusions, a new Cochrane review finds.

Use of glucagon-like peptide-1 (GLP-1) receptor agonists used to treat type 2 diabetes and obesity are associated with an increased risk of hair loss (alopecia) in adults with type 2 diabetes, finds a study published by The BMJ today.

Collagen is a protein found in skin, hair, nails, tendons, cartilage, and bones. Our bodies naturally produce collagen using the foods we eat. But, in recent years, collagen peptides have gained popularity as a supplement to support joint, hair, skin, and gut health.

Plasma exchange can help treat people with a rare inflammatory disease that can cause blindness, according to a systematic review and meta-analysis published on July 22, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Black people with multiple sclerosis (MS) die from MS at a younger age than white people, with a peak mortality rate at ages 65 to 74 for Black people and ages 75 to 84 for white people, according to a study published July 22, 2026, in Neurology® Open Access, an official journal of the American Academy of Neurology.

Sickle cell disease causes premature aging of blood stem cells, which scientists may be able to address with a special class of drugs, according to a new study from St. Jude Children's Research Hospital.

Motor issues-such as coordination problems, motor slowing, or sudden, uncontrolled movements-have been recognized as signs of psychological disorders since the 1800s. How they map to mental health conditions, however, remains unknown.

Three studies presented today at the Society of NeuroInterventional Surgery's (SNIS) 23rd Annual Meeting found that racial, geographic and socioeconomic disparities continue to influence stroke treatment and outcomes across the United States.

Occult hepatitis B virus (OBI) infection presents a significant global health challenge, notoriously flying under the radar of standard viral screening while relentlessly driving the pathogenesis of hepatocellular carcinoma (HCC).

In 465 young people followed from late childhood to late adolescence, EEG reward responses increased until mid-adolescence before declining by age 18. Higher positive parenting and lower negative parenting at age 3 predicted stronger developmental changes in neural responses to monetary rewards, while early stress exposure showed no significant association.

A systematic review and meta-analysis of 16 studies involving nearly 2 million participants found that higher red meat intake was associated with a modestly higher risk of pancreatic cancer. Processed meat intake showed no statistically significant association, although variation between studies means a small effect cannot be excluded.

ARIC researchers linked self-reported TV watching and occupational sitting in midlife with brain MRI measures obtained roughly 24 years later in 1,712 adults without dementia. Frequent TV watching was associated with greater white matter hyperintensity volume and lower volumes in several brain regions, while sitting at work was associated with lower white matter hyperintensity volume and larger selected cortical volumes.

Parkinson's disease (PD) is a progressive neurodegenerative disorder caused by the loss of dopamine-producing neurons, leading to motor symptoms such as tremors, rigidity, slowed movement, and impaired balance, as well as cognitive decline.

Immune checkpoint blockade (ICB) therapy has transformed cancer treatment, but many tumors remain resistant.

Curcumin, berberine, and other plant-derived compounds have long attracted scientific interest because of their anti-inflammatory and anticancer properties.
