Secret life of elephant seals not secret anymore!

...ded scientists with an unprecedented peek into the secret lives of seals. The measurements reveal in detail where the seals go on their winter feeding trips, where they find food and where they dont, and help explain why some populations have remained stable since 1950 while others have declined. The re...

Switchable adhesive

...ut the scientists led by Mark Geoghegan reveal the secret of their intelligent adhesion in the journal Angewandte Chemie. One of the surfaces involved consists of a polyacid gel, a three-dimensionally cross-linked polymer containing many acid groups. This polymer network is so heavily soaked in liquid tha...

Microscopic jets, diamonds unlikely on Uranus, and amazing mosquito legs

...ey pushed it down into a container of water. The secret to mosquito water walking appears to be feathery scales a few microns across that in turn are covered with nanoscopic ribbing, forming what the physicists have dubbed (in an apparent fit of excessive prefixing) a micronanostructure. So the next time ...

UVa-led team uncovers important secret in gene replication

Ultrathin films deliver DNA as possible gene therapy tool

... DNA] back out of the films is the hard part." The secret to films that release DNA is in the choice of the polymer and the layer-cake design. The researchers alternate layers of DNA with layers of a polymer that is stable when dry but that degrades when exposed to water. Because the polymers carry a posi...

Researchers learn what sparks plant growth

A secret long held by plants has been revealed by Howard Hughes Medical Institute researchers. The new discovery, which builds on more than a decade of painstaking surveillance of cellular communication between different types of plant tissues, shows clearly ...

Winners of the 2006 AAAS Science Journalism Awards

...s. Why? Quite by accident, the researchers found a secret defense system in living cells, a gene-silencing mechanism called RNA interference. It has become one of the hottest topics in biology and was the subject of the recently awarded 2006 Nobel Prize for Medicine or Physiology. In addition to the RNAi se...

Noise echoes in cell communications

.... "There is no life without noise; noise is the secret of life," suggests Martin, who points to the constant movement of particles under a microscope to illustrate this phenomena. Unlike a physics experiment that can produce the same result after various attempts, in biology, one particular experiment ca...
