A 'private bandwidth' for communication in bats: Evidence from insular horseshoe bats

... peninsular Italy (i.e. on the mainland). Why" The reason may be the presence of a third species, the Mehelys horseshoe bat (Rhinolophus mehelyi), practically absent on the mainland but abundant in Sardinia. This bat emits frequencies falling between the other two species: if Sardinian R..euryale and R. hip...

Interaction of just 2 genes governs coloration patterns in mice

...nteract to produce distinctive coloration. There's reason to believe this simple pathway may be evolutionarily conserved across mammals that display lighter bellies and darker backs, from mice to tuxedo cats to German Shepherds."

Satellite tracking reveals threats to Borneo pygmy elephants

...er for WWFs Species Conservation Program. The only reason we now have a good understanding of where these elephants travel from day to day is because satellite collar technology has given us access to the most inaccessible forests on Borneo. The information provided by the research might also help predi...

What we can learn from the biggest extinction in the history of Earth

...t the reef leave, and the reef loses color-and one reason why algae might leave is temperature. For example, when ocean temperatures rise during El Nio years, corals bleach. This type of immediate response to environmental change is hard to track in the geologic record. "We hope to reconcile the short-ter...

Why nectar-feeding bats need a 'power drink' to fly

...bolism directly from power drinks, they say. The reason these bats live on such an energetic knife edge is down to the food source they live on and the way they get around. They feed on floral nectars that contain simple sugars such as sucrose, glucose and fructose, but which are produced in only very sma...

Coelacanth fossil sheds light on fin-to-limb evolution

...re far too specialized, Coates said. Part of the reason why this is an interesting discovery is that people think of coelacanths animals as archetypal living fossils, said Matt Friedman, evolutionary biology graduate student at Chicago and lead author of the paper. But its a common misconception. If you l...

"Our hope is that this kind of information will equip clinicians to better manage prescribing of antibioti...

Negative effects of plastic's additive blocked by nutrient supplements

...ient in soy. It is possible, Jirtle said, that the reason Asians have much lower rates of obesity and certain cancers is that their diet typically includes greater use of soy products than Western diets. However, he pointed out, it is not known at what doses genistein would be protective or harmful in human...

St. Jude study solves mystery of mammalian ears

...nd in mammals, this would mean that prestin is the reason mammals amplify sound so efficiently, Zuo said. In the current study, Zuo and his team conducted a complex series of studies that showed in mammals that the role of somatic mobility driven by prestin is not simply to modify the response of the out...

Seawater intrusion is the first cause of contamination of coastal aquifers

In Southern Spain, seawater intrusion is contaminating some of the most important aquifer systems in economic terms, ...

Prenatal stress keeps infants, toddlers up at night, study says

...roblematic sleep is notable; it may be part of the reason why mood-disturbed pregnancies are linked to childrens behavioral disorders, like depression, hyperactivity and anxiety, later on down the road, OConnor said. It remains to be seen if the sleep problems we witnessed may play an active, causal role in...

Eat fish -- especially if you drink high levels of alcohol

...mpared to the LA levels, these results are further reason for concern over the ALA intake of alcoholics." "This helps to explain why alcohol abuse leads to losses in polyunsaturated fats in the circulation and organs," said Salem. "However, dietary influence does not explain all of the changes observed ...

Dr. Messersmith said the inspiration for the geckel nanoadhesive came about two years ago when he noticed an article about the adhesive force of a single hair from the...

CRESIB coordinates an international consortium to fight malaria caused by Plasmodium vivax

Hernando A. del Portillo, specialist in molecular biology and vaccine development against Plasmodium vivax , gives plenty of importance to the development of new control tools for this type of malaria. In the field of mala...

Crystal structure enables tailoring of pharmaceuticals against asthma

However, there is a need for new pharmaceutical alternatives, since not all patients respond to the existing medicines. Scientists at the Department of Medical Biochemi...

Now, researchers at the University of California, San Diego (UCSD) School of Medicine have discovered one important function of so-called junk DNA. Genes, which make up about four percent of the genome, encode for proteins, the building block...
