Specific gut bacteria may signal long-term risk of heart and metabolic disease

Researchers analyzed gut microbiome profiles from 4,792 adults in the HELIUS cohort and tracked cardiometabolic outcomes over time to determine whether specific microbes predict disease risk. Certain microbes were linked to higher or lower cardiovascular risk, while plant-derived microbial metabolites suggested potential diet–microbiome interactions influencing heart health.

Brain connectivity differences found in infants with congenital heart disease

The prevalence of congenital heart disease points to the need for a better understanding of how it influences neurodevelopment. New in JNeurosci, Jung-Hoon Kim and Catherine Limperopoulos, from Children's National Hospital, led a study examining brain network disruptions that may be linked to congenital heart disease.

New CRISPR technique boosts mitochondrial function to treat heart failure

After a heart attack, the heart struggles to recoup and maintain energy. One third of patients develop heart failure as a result ⎯ a condition that impacts 6.8 million Americans and carries a high lifetime risk with 1 in 4 adults in the U.S. expected to develop the condition during their lifetime.

Daily multivitamin intake linked to slower biological aging in older adults

An analysis led by Mass General Brigham investigators found slower aging in older adults after two years of a daily multivitamin, with greater benefits for those who began the trial with accelerated biological age.

Improving biological age gap may help protect long-term brain health

Improving the gap between your biological age and your chronological age is associated with a lower risk of stroke and improvements in signs of damage in the brain, according to a preliminary study released March 5, 2026, that will be presented at the American Academy of Neurology's 78th Annual Meeting taking place April 18-22, 2026, in Chicago and online.

Single injection may help the heart heal after heart attack

For people who have survived a heart attack, the notion of one shot in the arm to help the heart heal, for weeks after, may seem far‑fetched. But thanks to a team of researchers, including a Texas A&M University professor, that's exactly what could happen.
