- Bacterial toxin closes gate on immune response, Penn researchers discover
02-13-2008 · EurekAlert!
Researchers at the University of Pennsylvania School of Medicine have demonstrated that a bacterial toxin from the common bacterium Staphylococcus aureus shuts down the control mechanism of the tunnel, called an ion channel, in immune cell membranes. Shutting down ion channels has long been known to suppress the immune response, and the bacteria may use the toxin to neutralize host defenses against bacteria.

- How fishes conquered the ocean
01-23-2007 · EurekAlert!
Scientists at the University of Bergen, Norway have deduced how bony fishes conquered the oceans by duplicating their yolk-producing genes and filling their eggs with the water of life -- the degradation of yolk proteins from one of the duplicated genes causes the eggs to fill with vital water and float. This is the major solution realized by extant marine teleosts that showed an unprecedented radiation during the late Cretaceous and early Paleogene Periods.

- Hard as nails!
03-31-2007 · EurekAlert!
Most people know that their nails always go soft and bendy when they immerse them in hot water for any length of time. Conversely when you cut your nails they dry up and become hard and brittle. But why is this? Biologists working with material scientists at the University of Manchester have worked out the best conditions for our nails which may ultimately help the cosmetic industry to mimic the real thing and refine their false nail and varnish products.

08-29-2007 · EurekAlert!
One of the most distinctive characteristics of humans is probably one you don't think of very often -- the capacity to learn based merely on what someone tells you. Researchers from Boston University are attempting to discover when when we become capable of revising our mental representations of objects or situations based solely on what someone tells us.
