...initiating EMT. CBF-A and KAP-1 were shown, by two independent mechanisms, to bind a regulatory region of DNA in the gene encoding FSP1. This regulatory region of DNA is known as FTS-1 and the binding of proteins to FTS-1 has previously been shown to drive the expression of FSP1. Further analysis by Neilson and ...

Rats on a road trip reveal pollution-heart disease risk

Bats in flight reveal unexpected aerodynamics

...s are highly articulated, with more than two dozen independent joints and a thin flexible membrane covering them. The videos, shot from four angles simultaneously and then synchronized, show how the complex movements of each wing stroke relate to overall flight speed, body position and angle of attack.

40,000-year-old skull shows both modern human and Neandertal traits

... there were some important differences: apparently independent features that are, at best, unusual for a modern human. These included frontal flattening, a fairly large juxtamastoid eminence and exceptionally large upper molars with unusual size progression which are found principally among the Neandertals. Pr...
