Common insecticide is harmful to bees in any amount  

The dangers of neonicotinoid insecticides likely can't be watered down. That's the conclusion of a new study showing an insecticide made for commercial plant nurseries is harmful to a typical bee even when applied well below the label rate and the plant receives high levels of irrigation.

Plastic creates 'evolutionary trap' for young sea turtles  

Plastic pollution creates an 'evolutionary trap' for young sea turtles, new research shows. After hatching on beaches, sea turtles travel on currents and spend their early years in the open ocean. But these currents now accumulate vast quantities of plastic and -- feeding near the surface -- many young turtles swallow it.

Atomic-level, 3-D structure of MUTYH protein opens small window into DNA repair mechanism  

A research team has analyzed the three-dimensional structure of a protein that suppresses the development of colorectal polyposis, MUTYH, at the atomic level and clarified the repair mechanism for DNA mispairings. Since mutations in the MUTYH gene cause heritable colorectal polyposis, which leads to colorectal cancer, the researchers expect that this work will be useful for future research on heritable colorectal polyposis associated with MUTYH.

Overcoming this barrier may be a first step in returning inner ear cells to a newborn-like state that's primed for regeneration, as described in a new study. The study suggests new gene engineering approaches that could be used to channel some of the same regenerative capability present in embryonic inner ear cells.
