Colored patches represent parallelogram outlines around pairs of triangles that have formed chiral super-structures. Parallelograms having different "handedness " and orientations are color-coded and superimposed over each other. The overwhelming majority of proteins and other functional molecules in our bodies display a striking molecular characteristic: They can exist in two distinct forms that are mirror images of each other, like your right hand and left hand. Surprisingly, each of our bodies prefers only one of these molecular forms.

Scientists from Queen Mary, University of London have found a new therapeutic target to combat inflammation.

Scientists at the University of Liverpool have found that genetic information on the Antarctic octopus supports studies indicating that the West Antarctic Ice Sheet could have collapsed during its history, possibly as recently as 200,000 years ago.

The critically endangered Atlantic goliath grouper, Epinephelus itajara, is from the subtropical and tropical Atlantic. Groupers, a family of fishes often found in coral reefs and prized for their quality of flesh, are facing critical threats to their survival. As part of the International Union for Conservation of Nature (IUCN) Species Survival Commission, a team of scientists has spent the past ten years assessing the status of 163 grouper species worldwide. They report that 20 species (12%) are at risk of extinction if current overfishing trends continue, and an additional 22 species (13%) are Near Threatened. These findings were published online on April 28 in the journal Fish and Fisheries.
