Impaired cell division leads to neuronal disorder

Posted: 31 Jan 2014 07:11 AM PST

Researchers have discovered an amino acid signal essential for error-free cell division. This signal regulates the number of centrosomes in the cell, and its absence results in the development of pathologically altered cells. Remarkably, such altered cells are found in people with a neurodevelopmental disorder, called autosomal recessive primary microcephaly.

Nine steps to save waterways and fisheries identified by researchers

The key to clean waterways and sustainable fisheries is to follow nine guiding principles of water management, says a team of Canadian biologists.

Lemur lovers sync their scents: Strength of a lemur couple's bond is reflected in the similarity of their scents

Posted: 31 Jan 2014 05:35 AM PST

Mating pairs of lemurs mirror each other's scent-marking behavior and even start to smell alike after they have reproduced. Matched scents are possibly a way to combine territory defenses or to advertise their relationship status to the rest of their group, according to researchers. Couples who haven't had kids yet spend the most time scent-marking and investigating each other's odors.

Vibrations influence circadian clock of fruit fly

The internal circadian clock of a Drosophila (fruit fly) can be synchronized using vibrations, according to new research. The results of the study suggest that an animal's own movements can influence its clock.

Gastric bypass improves insulin secretion in pigs

Posted: 31 Jan 2014 05:34 AM PST

The majority of gastric bypass patients mysteriously recover from their type 2 diabetes within days, before any weight loss has taken place. A study has now shown that the insulin-producing beta cells increase in number and performance after the surgery.

Teaching young wolves new tricks: Wolves are considerably better imitators than dogs

Posted: 31 Jan 2014 05:34 AM PST

Although wolves and dogs are closely related, they show some striking differences. Scientists have undertaken experiments that suggest that wolves observe one another more closely than dogs and so are better at learning from one another. The scientists believe that cooperation among wolves is the basis of the understanding between dogs and humans.

New catalyst to convert greenhouse gases into chemicals

Posted: 31 Jan 2014 05:32 AM PST

Researchers have developed a highly selective catalyst capable of electrochemically converting carbon dioxide -- a greenhouse gas -- to carbon monoxide with 92 percent efficiency. The carbon monoxide then can be used to develop useful chemicals.

Diagnosis just a breath away with new laser that advances breath analysis for disease diagnosis

Posted: 31 Jan 2014 05:32 AM PST

Physics researchers have developed a new type of laser that will enable exciting new advances in areas as diverse as breath analysis for disease diagnosis and remote sensing of critical greenhouse gases.
