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…

New study offers insights into designing safe, effective nasal vaccines
Most vaccines — and boosters — are injected directly into muscle tissue, usually in the upper arm, to kickstart the body’s immune system in the fight against disease. But for respiratory diseases like COVID-19, it can be important to have protection right where the virus enters: the…

New study reveals our skin’s own bacteria can help protect us from the bad effects of sunlight
The skin microbiome plays an important role in health and disease. Researchers have now substantiated that certain skin bacteria can protect us from the sun’s ultraviolet (UV) radiation specifically by metabolizing cis-urocanic acid using an enzyme called urocanase. This enables the skin’s…

Drinking water, select foods linked to PFAS in California adults
While concentrations of older “forever” chemicals appear to have decreased in many foods over the last two decades, a new study found that drinking water, along with seafood, eggs, and brown rice, still contribute to PFAS exposure in adults. More attention is needed to newer, replacement PFAS.

Exercise the key to maintaining Vitamin D levels in winter
The sun may be shining now, and our vitamin D levels are getting a natural boost but it wasn’t long ago we were in the depths of winter, when sunlight was scarce and vitamin D was in short supply.
Now, new research from the University of Bath, University of Birmingham, University of Cambridge…

Yellow fever vaccination: How strong immune responses are triggered
Researchers show how specific immune cells are activated by the vaccine — an important starting point for the development of new vaccines.
The yellow fever vaccination using the live-attenuated YF17D vaccine is one of the most effective immunizations available. A single dose provides…

New insights into the energy balance of brain neurons
A research team at the Carl Ludwig Institute for Physiology at Leipzig University has, for the first time, demonstrated how the energy levels of individual neurons in the brain change during so-called spreading depolarizations — waves of activity that occur in various brain disorders. The…
