...tter of degree. The Pitt researchers say that in light of their results, treatments that completely abolish a specific component of the inflammatory response would be ineffective, and could be dangerous, since the inflammatory response is needed to address the underlying infection. Instead, they believe...Beyond batteries: Storing power in a sheet of paper
...in small handheld electronics, the paper batteries light weight could make them ideal for use in automobiles, aircraft, and even boats. The paper also could be molded into different shapes, such as a car door, which would enable important new engineering innovations. Plus, because of the high paper conte...Interaction of just 2 genes governs coloration patterns in mice
...mutations in both genes that produces a mouse very light in color. "Thus, two different types of mutations in two different genes each contribute to the light coloration of beach mice," Hoekstra says.

This protein and a second key player were already known to trigger cells to move, but their interaction to generate the self-sustaining waves has now been revea...Protein 'chatter' linked to cancer activation

...Energy's Argonne National Laboratory have cast new light on why the giant insects that lived millions of years ago disappeared. In the late Paleozoic Era, with atmospheric oxygen levels reaching record highs, some insects evolved into giants. When oxygen levels returned to lower levels, the insect giants...Circadian clock controls plant growth hormone
