Endangered Animals Can Be Identified by Rate of Genetic Diversity Loss

Aug. 31, 2015 — A new study presents a novel approach for identifying vertebrate populations at risk of extinction by estimating the rate of genetic diversity loss, a measurement that could help researchers and ... read more

Aug. 31, 2015 — Among birds, the line between species is often blurry. Some closely related species interbreed where their ranges overlap, producing hybrid offspring. In the coastal marshes of New England, this has ... read more

Batting Practice in the Genome

Aug. 25, 2015 — In the biochemical game of genetics, it was thought that the proteins controlling gene regulation in animals were either spectators or players. But scientists have now found that spectator proteins ... read more

Aug. 20, 2015 — Bacteria do not cease to amaze us with their survival strategies. A research has now discovered how bacteria enter a sleep mode using a so-called FIC toxin. In a new article, the scientists describe ... read more

Genome-Wide Annotation of Primary miRNAs Reveals Novel Mechanisms

Aug. 19, 2015 — MicroRNAs are short noncoding RNAs that play critical roles in regulating gene expression in normal physiology and disease. Despite having tightly controlled expression levels, little is known about ... read more

Aug. 19, 2015 — Animal sex signals, communications between partners indicating health, the capacity to produce healthy offspring and more, were thought to be beneficial and passed down from generation to generation. ... read more

Aug. 19, 2015 — Plants and animals, including humans, are not autonomous individuals but are holobionts: biomolecular networks that consist of visible hosts plus millions of invisible microbes, recent ... read more

Aug. 19, 2015 — An international research team has some good news for the struggling honeybee, and the millions of people who depend on them to pollinate crops and other plants. These valuable pollinators have faced ... read more

Aug. 18, 2015 — New species evolve whenever a lineage splits off into several. Because of this, the kinship between species is often described in terms of a 'tree of life,' where every branch constitutes a ... read more

Aug. 18, 2015 — A cooling, drying climate over the last 40 million years turned North America from a warm and wooded place into the drier, open plains we know today. A new study shows how dogs evolved in response to ... read more

Aug. 18, 2015 — A study of catsharks reveals how alterations in the expression and function of certain genes in limb buds underlie the evolution of fish fins to limbs. The findings give new insight into how fish ... read more

Aug. 17, 2015 — Paleobotanists in Europe have identified a 125 million- to 130 million-year-old freshwater plant as one of earliest flowering plants on ... read more

Aug. 14, 2015 — Frolicking, wrestling, climbing, jumping -- Playing is a lot of fun and promotes development but is also very strenuous. Behavioral biologists therefore suspect that animals only play intensively if ... read more

Aug. 12, 2015 — Computer scientists have found that robots evolve more quickly and efficiently after a virtual mass extinction modeled after real-life disasters such as the one that killed off the dinosaurs. Beyond ... read more

Evolution Peaks on Tropical Mountain

Aug. 12, 2015 — Tropical mountains have an exceptionally high biodiversity. This is also the case for Mount Kinabalu in Sabah, Malaysian Borneo. During an expedition, experts investigated the local fauna, flora, and ... read more

Aug. 12, 2015 — Imagine a skeleton-less creature with three hearts, with most of its nearly half a billion neurons distributed in eight tentacular arms. Each arm can regenerate like the mythical Hydra and has a mind ... read more

Aug. 12, 2015 — Competition played a more important role in the evolution of the dog family (wolves, foxes, and their relatives) than climate change, shows a new international study. Researchers analyzed over 2000 ... read more

Aug. 11, 2015 — From Austrian monks to American craft brewers, beer geeks are everywhere. But making a good beer not only depends on the best ingredients, but also the best yeast. Lagers now represent a whopping 94 ... read more

Aug. 11, 2015 — The evolutionary loss of the 'altruistic' worker caste in ants is not accompanied by a loss of genes, an international team of researchers has found. The results reported in this new ... read more
