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.

Hormone FGF21 reverses fatty liver disease by signaling the brain

A pioneering research study published today in Cell Metabolism details how the hormone FGF21 (fibroblast growth factor 21) can reverse the effects of fatty liver disease in mice. The hormone works primarily by signaling the brain to improve liver function.
