Who in the world can afford healthy food? Global study measures the cost of a nutritious diet

Putting the brakes on an enzyme might rescue neurons that are dying due to a type of Parkinson's disease that's caused by a single genetic mutation, according to a new Stanford Medicine-led study conducted in mice.

Delirium affected 44% of critically ill patients in an Ohio medical center who were hospitalized after a recent stroke, according to new research published in the American Journal of Critical Care. Incidence rates were highest for patients with intracerebral hemorrhage (ICH), with 60% having delirium for at least one day.

Researchers at Tohoku University have discovered that an oral drug called MA-5 can improve both heart and muscle problems in Barth syndrome, a rare genetic disorder affecting 1 in 300,000 births worldwide with no current cure.

Scientists from Trinity College Dublin are assessing how the development of spinal ligaments provide mechanical stability and impact postural support in the spine—with a view to better understanding how developmental "missteps" may contribute to spinal deformations, such as the characteristic curved spines that develop in people with scoliosis.

Special districts established to control mosquitoes in parts of Florida claim significantly more funding and expertise than county-run programs, finds a new analysis co-authored by a Cornell public health expert.

Moderna's new flu vaccine, based on the same mRNA technology used in its COVID-19 shot, showed promising results in a major trial, the company announced Monday.

Waking up from a nightmare can leave your heart pounding, but the effects may reach far beyond a restless night. Adults who suffer bad dreams every week were almost three times more likely to die before age 75 than people who rarely have them.

On Monday, the U.S. Supreme Court said it will not hear a case brought by a group once led by U.S. Health Secretary Robert F. Kennedy Jr. that claimed Facebook censored its vaccine-related content.

President Donald Trump's budget proposal for fiscal year 2026 requests significant reductions to HIV prevention and surveillance programs while preserving other parts of the Ryan White HIV/AIDS Program, the nation's HIV care and treatment safety net.

A recent study by the Norwegian University of Science and Technology (NTNU) has found that children born in October, November or December are statistically more often identified as having a mental health diagnosis than their classmates born earlier in the year. The findings apply to both boys and girls, and regardless of whether they were born full term or prematurely.

A potential treatment for glioblastoma crafted by scientists at The Wertheim UF Scripps Institute renders the deadly brain cancer newly sensitive to both radiation and chemotherapy drugs, and blocks the cancer's ability to invade other tissues, a new study shows.

Scientists have long known that the brain's visual system isn't fully hardwired from the start—it becomes refined by what babies see—but the authors of a new MIT study still weren't prepared for the degree of rewiring they observed when they took a first-ever look at the process in mice as it happened in real-time.

A new study by researchers in the Department of Clinical Neuroscience, Karolinska Institutet, has identified 18 potential drug targets for the treatment of multiple sclerosis. The study may pave the way for new treatment strategies and drug development.

Mouthwashes have long bragged about killing 99.9% of germs in your mouth, but Rutgers Health researchers suggest this scorched-earth approach may harm oral health by eliminating beneficial bacteria along with the bad.

New research from Aston University has shone a light on the best ways for parents to encourage healthy eating in their children. The paper is published in the International Journal of Behavioral Nutrition and Physical Activity.

GABA, or gamma-aminobutyric acid, is an amino acid functioning as the principal inhibitory neurotransmitter that can act on the brain to slow or stop the reception of certain signals to the brain, leading to a calmer and more relaxed state. Low GABA levels in the brain have been associated with neurological disorders and diseases like depression, Alzheimer's or epilepsy.

Hypertension affects 1 in 3 adults globally and is the leading modifiable risk factor for cardiovascular disease. Aldosterone dysregulation, often driven by obesity and primary aldosteronism, affects up to 30% of patients with hypertension, many of whom are undiagnosed or untreated.

Can a monkey, a pigeon or a fish reason like a person? It's a question scientists have been testing in increasingly creative ways—and what we've found so far paints a more complicated picture than you'd think.
