April Flowers for redOrbit.com - Your Universe Online In a hive of honey bees, the jobs of queen and worker are drastically different. A new study from Michigan State University and Wayne State University reveals, however, that only a single gene separates the two. The findings, published in Biology Letters, show this gene not only determines leg and wing development, but it also plays a crucial role in the evolution of bees' ability to carry pollen. “This gene is critical in making...

An international research team including Christian Schlötterer and Alistair McGregor of the Vetmeduni Vienna has discovered a completely new mechanism by which evolution can change the appearance of an organism.  The researchers found that the number of hairs on flies´ legs varies according to the level of activity of a so-called microRNA.  The results, published in the journal Current Biology, shed a completely new light on the molecular mechanisms of evolution....

Rice, Texas A&M labs create protein-patterned fibers Researchers at Rice University and Texas A&M have discovered a way to pattern active proteins into bio-friendly fibers. The "eureka" moment came about because somebody forgot to clean up the lab one night. The new work from the Rice lab of biochemist Kathleen Matthews, in collaboration with former Rice faculty fellow and current Texas A&M assistant professor Sarah Bondos, simplifies the process of making materials with fully...

Water striders, the familiar semi-aquatic bugs gliding across the lake at the cottage, have a novel body form that allows them to walk on water.  This was not always the case.  Achieving the gliding ability required the evolution of a unique arrangement of the legs, with the mid-legs greatly elongated. Scientists at the University of Toronto's Department of Ecology and Evolutionary Biology have discovered the gene behind this evolutionary change.Called the Hox gene, Ultrabithorax,...
