Viral circRNAs Sponge Up Host miRNAs to Weaken Immune Response

In a significant breakthrough, researchers from Florida Atlantic University’s Charles E. Schmidt College of Medicine have uncovered a previously unknown mechanism that allows the human immunodeficiency type 1 virus (HIV-1) to evade the body’s natural defenses, thereby facilitating its survival and replication.

New Neural Circuit Discovery Explains Precision Steering in Fruit Flies

When a fruit fly is navigating straight forward at high speed, why does it know that it's not straying off course? Because as long as the fly moves directly forward, the visual scene shifts from front to back in a near-perfect mirror image across both retinas – generating, in other words, a symmetrical visual motion pattern.
