Depressione: scoperto un legame con la cattiva comunicazione dei neuroni

Un nuovo studio della University of Maryland School of Medicine ha mostrato che la depressione affonda le sue radici in una cattiva comunicazione...

Ultrabatteri: i ceppi resistenti a qualsiasi trattamento antibiotico

Invulnerabili a qualsiasi attacco. La marcia dei super-batteri, in grado di resistere a tutti gli antibiotici disponibili, sembra inarrestabile. E potrebbe presto fare più...

Sistema immunitario e nanoparticelle

La nanotecnologia è un'innovazione talmente nuova che nessuno è davvero sicuro di cosa produrrà. Le previsioni spaziano dalla capacità di riprodurre oggetti come diamanti...

Termites’ digestive system could act as biofuel refinery

One of the peskiest household pests, while disastrous to homes, could prove to be a boon for cars, as per a Purdue University study. Mike Scharf, the O. Wayne Rollins/Orkin Chair in Molecular Physiology

New not-so-sweet potato resists pests and disease

Researchers from Clemson University and the USDA Agricultural Research Service have developed a new variety of not-so-sweet potato, called Liberty. Known as a boniato, or tropical sweet potato, Liberty has a dark red skin and light yellow, dry flesh with a bland flavor. Boniato potatoes originated in the tropical Americas and are grown in south Florida in the United States. They can be served fried, mashed or in soup........

Life-history traits may affect DNA mutation rates

For the first time, researchers have used large-scale DNA sequencing data to investigate a long-standing evolutionary assumption: DNA mutation rates are influenced by a set of species-specific life-history traits. These traits include metabolic rate and the interval...

Solving mouse genome dilemma

Laboratory research has always been limited in terms of what conclusions researchers can safely extrapolate from animal experiments to the human population as a whole. A number of promising findings in mice have not held up under further experimentation, in part because laboratory animals, bred from a limited genetic foundation, don't provide a good representation of how genetic diversity manifests in the broader human population........

Killer whales in Antarctic waters prefer weddell seals

NOAA's Fisheries Service researchers studying the cooperative hunting behavior of killer whales in Antarctic waters observed the animals favoring one type of seal over all other available food sources, as per a research studyreported ...
