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

Researchers Reverse Bacterial Resistance to Antibiotics in Lab

May 6, 2015 — The rise of antibiotic-resistant bacteria is a growing problem in the United States and the world. New findings by researchers in evolutionary biology and mathematics could help doctors better ... read more

May 6, 2015 — A scientist who discovered a new Scottish flower has made an unexpected second finding that provides unique insight into our understanding of evolution. The original find was made even more rare ... read more

May 6, 2015 — Diets of snakes from a temperate region in South America may depend more on phylogeny (ancestry) than ... read more

May 6, 2015 — Biologists have discovered a new microbe that represents a missing link in the evolution of complex life. The study provides a new understanding of how, billions of years ago, the complex cell types ... read more

What Happens When Populations Hit the Borders of Expansion?

May 5, 2015 — Scientists are researching how population size and genetic drift affect the limits to a species' range. In a new article, they explain why sharp range margins arise in natural ... read more

May 4, 2015 — Bioluminescence at least in one millipede may have evolved as a way to survive in a hot, dry environment, not as a means to ward off predators, according to ... read more

May 4, 2015 — Is there a sixth DNA base? A team of researchers suggests that the methyl-adenine that would regulate the expression of certain genes in eukaryotic cells could have a specific role in stem cells and ... read more

Apr. 27, 2015 — A research collaboration has shed light on the genome of two commercially important species of bumblebees. The findings provide unexpected insights into the ecology and evolution of bumblebees and ... read more
