Flavan-3-ols in tea and chocolate can lower blood pressure

We might have another reason to enjoy our daily cup of tea or small piece of dark chocolate, as a new study from the University of Surrey has found that naturally occurring compounds called flavan-3-ols - found in cocoa, tea, apples and grapes - may improve blood pressure and the health of our blood vessels.

Gum disease bacterium linked to increased risk of atrial fibrillation

Tempted to skip the floss? Your heart might thank you if you don't. A new study from Hiroshima University (HU) finds that the gum disease bacterium Porphyromonas gingivalis (P. gingivalis) can slip into the bloodstream and infiltrate the heart.

Study links sleep apnea to damage in brain areas critical for memory

Obstructive sleep apnea, a condition that causes lower oxygen levels during sleep, is linked to degeneration of brain regions associated with memory through damage to the brain's small blood vessels, according to a study published May 7, 2025, online in Neurology, the medical journal of the American Academy of Neurology.

Macrophages take center stage in liver healing after injury

The liver is famous for its remarkable ability to regenerate, but that healing power depends heavily on the actions of its resident immune cells. A new study spotlights macrophages, the liver's cleanup and repair specialists, revealing that these cells quickly adapt after injury to clear debris and support tissue recovery.

Healthy diet in childhood linked to later onset of menstruation

Eating a healthy diet as a child is linked to girls having their first menstrual period at an older age than those who consumed a less healthy diet, according to a new study published today (Wednesday) in Human Reproduction, one of the world's leading reproductive medicine journals.

Hidden heart and lung damage detected in patients with long COVID

Patients suffering from long COVID may exhibit persistent inflammation in the heart and lungs for up to a year following SARS-CoV-2 infection-even when standard medical tests return normal results-potentially placing them at elevated risk for future cardiac and pulmonary conditions.

Can your diet slow skin aging? New review reveals what helps and what harms

Scientists reviewed recent studies and found that antioxidant-rich diets help slow skin aging, while high intake of refined sugars and trans fats accelerates it. A balanced, nutrient-dense diet may be a practical way to protect skin health and delay visible signs of aging.

Low blood sugar linked to retinal damage in diabetic eye disease

In a new National Institutes of Health-funded study led by scientists at the Wilmer Eye Institute, Johns Hopkins Medicine researchers say they have determined that low blood sugar, or hypoglycemia, may promote a breakdown of the blood-retinal barrier, an important boundary that regulates the flow of nutrients, waste and water in and out of the retina.

Hairlike electrodes offer a new era for comfortable EEG monitoring

The future of electroencephalography (EEG) monitoring may soon look like a strand of hair. In place of the traditional metal electrodes, a web of wires and sticky adhesives, a team of researchers from Penn State created a hairlike device for long-term, non-invasive monitoring of the brain's electrical activity.

TDP-43 dysfunction in brain blood vessels may drive Alzheimer's and ALS progression

Reduced levels of a critical protein are linked to devastating brain diseases like Alzheimer's, frontotemporal dementia, and amyotrophic lateral sclerosis (ALS). Surprisingly, the protein shortage primarily affects the brain's blood vessels.

New protein target offers hope for treating high blood pressure and aortic aneurysms

Oxidative stress can occur when our cells are exposed to harmful molecules called "reactive oxygen species" over time. These reactive oxygen species can damage cells and are found in important disease states, such as high blood pressure and aortic aneurysms.
