New insights into the structure and function of Cdc34, a target for cancer therapeutics
Researchers report they have obtained 3D structural snapshots of Cdc34 in action. Cdc34 is an enzyme important for cell cycle regulation and a target for therapeutic intervention in cancer. These structures, along with studies in human cells, have revealed key features of this enzyme important for its regulation of cell growth and activity. These unique features could present opportunities for rational design of novel cancer therapeutics.

For nearly 70 years, researchers believed that near-miss events like these would encourage you to continue gambling. But new research suggests that the near-miss effect may not exist at all.
Read moreEvidence of behavioral, biological similarities between compulsive overeating and addiction
Does yo-yo dieting drive compulsive eating? There may be a connection. According to researchers the chronic cyclic pattern of overeating followed by undereating, reduces the brain's ability to feel reward and may drive compulsive eating. This finding suggests that future research into treatment of compulsive eating behavior should focus on rebalancing the mesolimbic dopamine system — the part of the brain responsible for feeling reward or pleasure.

Biologists have described a new species of praying mantis that displays the first documented example of conspicuous mimicking of a wasp among praying mantises.
Read moreHow plant roots grow hair
The roots of plants can do a lot of things: They grow in length to reach water, they can bend to circumvent stones, and they form fine root hairs enabling them to absorb more nutrients from the soil. A team of researchers has now identified an important regulator of this process.
