"We have worked out the spatial footprint ?the data are strong and show that the farms are having a significant impact over a very large area." The researchers isolated the effect of the salmon f...

Molecular machine may lead to new drugs to combat human diseases

...e molecular machines, which are chemical complexes known as a Group I intron, at mid-point in its work cycle. When frozen, crystallized introns reveal their structure and the sites at which they bind with various molecules to cause biochemical reactions.

Enzyme allows B cells to resist death, leading to leukemia

...d altered cellularlocation of an enzyme in B cells known as Lyn, contributes to thedevelopment of B-CLL. The authorsexamined leukemia cells from 40 patients with B-CLL and compared themwith lymphocytes from normal donors. They found that Lyn was markedlyoverexpressed in CLL cells and an unusual amount of ...

In the sea slug's defense against lobsters, confusion is key

...acked by predatory spiny lobsters, sea slugs (also known as sea hares) release an inky secretion, termed ink and opaline, from a pair of glands. The new findings show that Aplysia's defensive secretion includes a variety of chemicals that together comprise a multi-pronged attack on the predator's nervous s...

A complete surprise Most regions of the chromatin have only a few "on" tags, but in regions packaging clusters of HOX genes hundreds of such tags exist. Yeast cells don't have such clusters, but HOX clus...
