Fix for 3-billion-year-old genetic error could dramatically improve genetic sequencing
Researchers found a fix for a 3-billion-year-old glitch in one of the major carriers of information needed for life, RNA, which until now produced errors when making copies of genetic information. The discovery will increase precision in genetic research and could dramatically improve medicine based on a person's genetic makeup.

Why fathers don't pass on mitochondria to offspring
Offering insights into a long-standing and mysterious bias in biology, a new study reveals how and why mitochondria are only passed on through a mother's egg -- and not the father's sperm.

Arms race at the plant root: How soil bacteria fight to escape sticky root traps
Soil is full of microbes. Specialized border cells at the outer surface of plant roots fight off these microbes as the roots penetrate the soil in search of water and nutrients. A new study reveals how plant pathogens fight back against entrapment by sticky root border cell secretions.

Running releases protein associated with improved memory in mice
The reason why treadmill training can boost memory recall remains an active area of investigation. A couple of proteins have been shown to fuel exercise-induced neuron growth, but a new study presents a new candidate, cathepsin B -- one that can be directly traced from the muscles to the brain in mice. Also, after a run, protein levels increased in blood in mice, monkeys, and humans.

The call of the sea: Mammalian evolutionary transitions back to the sea
Though mammals adapted on land, a new study has shown that during three major independent evolutionary events, a number of mammals hearkened back to the sea.

Negative feedback loops help maintain the function of mutated proteins
Negative feedback is a universal control mechanism that lets a system's output throttle its input. If an engine revs up, negative feedback tapers its power source. But if the engine slows down, it re-opens the power source, keeping output reliably steady. This is an example of a negative feedback that can be found in many systems.

In worldwide chemotaxis competition, researchers race cell lines to the finish line
Neutrophil-like cells must balance speed against chemotactic accuracy to win a chemotaxis maze race in the inaugural Dicty World Races, a worldwide competition.
