Skin microbiome plays active role in sun protection and immune balance

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.

Researchers map brain networks involved in word retrieval

How are we able to recall a word we want to say? This basic ability, called word retrieval, is often compromised in patients with brain damage. Interestingly, many patients who can name words they see, like identifying a pet in the room as a "cat", struggle with retrieving words in everyday discourse.

HIV uses circular RNAs to evade immunity and boost replication

In a groundbreaking discovery, researchers from Florida Atlantic University's Charles E. Schmidt College of Medicine have identified a never-before-seen mechanism that enables the human immunodeficiency type 1 virus (HIV-1) to evade the body's natural defenses and use it to support its survival and replication.

New insights into how the brain creates a unified visual experience

People have a lot of misconceptions about what the brain's left and right hemispheres do, but one well-known aspect of this division may be even more true than people realize: The brain not only splits up visual spatial perception-processing what's on our left in the right hemisphere and what's on our right in the left hemisphere-it takes cognitive advantage of that.

Just a few plant-based swaps a week could make a difference to your heart

Replacing small weekly amounts of red or processed meat with plant-based foods was linked to modest reductions in cardiovascular disease risk in a large Finnish cohort study. The benefits varied by gender and food type, with the most consistent improvements seen when processed meat was replaced with vegetables.
