May 12, 2015 — Pollution from historic mining activities in south west England has led to a reduction in genetic diversity of brown trout according to new research. The findings indicate that human activity can ... read more

May 14, 2015 — Explaining the evolution of insect society, with sterile society members displaying extreme levels of altruism, has long been a major scientific challenge, dating back to Charles Darwin's day. A ... read more

Belgian Shepherd Dogs Seem to Have Genetic Protection Against Diabetes

May 14, 2015 — A genetic interaction which may protect Belgian shepherd dogs from developing diabetes has been discovered by researchers. In this breed, the scientists found a novel mechanism of regulating blood ... read more

May 12, 2015 — Scientists have successfully replicated the molecular processes that led from dinosaur snouts to the first bird ... read more

May 11, 2015 — When it comes to winning evolutionary fitness races, the tortoise once again prevails over the hare. Scientists have found that limiting migrations among populations of bacteria produced better ... read more

May 11, 2015 — Transposable elements are DNA sequences that are capable of changing their genome position by cut and paste or copy and paste through the enzyme transposase. This ability can be harmful for hosts if ... read more

May 11, 2015 — The water flea has genetically adapted to climate change. Biologists compared 'resurrected' water fleas -- hatched from 40-year-old eggs -- with more recent specimens to reach this ... read more

All Invasive Parakeets Come from a Small Region in South America

May 11, 2015 — The parakeets that have invaded Europe and North America over the last forty to fifty years, creating massive nests in many urban areas, seem to have originated from the same small geographical area ... read more

May 7, 2015 — The discovery of a 500-million-year-old fossilized brain has helped identify a point of crucial transformation in early animals, and answered some of the questions about how heads first ... read more

May 7, 2015 — Wild-type zebrafish consistently beat out genetically modified Glofish in competition for female mates, an advantage that led to the disappearance of the transgene from the fish population over time, ... read more

May 7, 2015 — Newly evolved genes can rapidly assume control over fundamental functions during early embryonic development. The findings suggest that evolutionary changes to the genetics of fundamental biological ... read more

May 6, 2015 — How to protect your chicks from predators? Build a dome over them! There is tremendous diversity among the nests of birds, in nest location, structure, materials, and more, but we know very little ... read more
