Hummingbird evolution soared after they invaded South America 22 million years ago
A newly constructed family tree of the hummingbirds, published today in the journal Current Biology, tells a story of a unique group of birds that originated in Europe, passed through Asia and North Americ ...
Breakthrough DNA study could slow big cat extinction
New research comparing genes from living lions with ancient lion remains could help scientists boost dwindling populations.
Sugar responsible for shoot branching in plants
(Phys.org) —A University of Queensland study has overturned the long-held belief that plant hormones control the shape of plant growth, and shown instead that this process starts with sugar.
Scientists grow longer-lasting salad greens
Researchers at the University of Southampton have helped to produce salads with a longer shelf-life.
Exploring a microbial arms race
A rapid evolutionary "arms race" between bacteria and the killer viruses they contain has been observed by a UNSW-led team of scientists in a sophisticated genetic study of the micro-organisms.
Researchers find steep decline in invasive crab population
Delaware's native mud crabs were on the verge of being completely edged out by invasive Asian shore crabs 10 years ago. Today, new research shows that the tables have unexpectedly turned.

Efficient analysis of small quantity of cells improves chances to understand disease
For more than a decade Chang Lu, associate professor of chemical engineering at Virginia Tech, has worked on the development of tools to efficiently analyze living cells. The long-term goal is to gain a better understanding ...
Mercury contamination threatens Antarctic birds
Mercury contamination in the Antarctic and Subantarctic affects bird populations, reveal researchers from the Centre d'Etudes Biologiques de Chizé and from the 'Littoral, Environnement et Sociétés' Laboratory ...
Unpacking the past: Identifying a key evolutionary step in E. coli metabolism
Tiny male spiders can get a leg over—as long as they're picky
Males will mate with anything. Well, that is the general view, one that exists because of a simple biological underpinning: females are reproductively limited by costly gestation, while males are only limited ...
First functional 'designer' chromosome synthesized in yeast
An international team of scientists led by Jef Boeke, PhD, director of NYU Langone Medical Center's Institute for Systems Genetics, has synthesized the first functional chromosome in yeast, an important step ...
