Mimicry helps sheep solve a dilemma Posted: 02 Oct 2015 07:33 AM PDT Imitation behaviors play a key role in many collective phenomena seen in animals. An analysis of the collective movements of grazing sheep has revealed that sheep alternate slow dispersion phases with very fast regrouping, in which they imitate the behavior of their neighbors. This study shows that the intensity with which the sheep mimic one another plays a crucial role in the ability of a herd to maximize the grazing area explored while minimizing the time needed to regroup when faced with potential dangers.

Members of this genus live in Africa, the Canary Islands, Europe, and Asia.

Fusion reactors 'economically viable' say experts Posted: 02 Oct 2015 07:33 AM PDT Fusion reactors could become an economically viable means of generating electricity within a few decades, and policy makers should start planning to build them as a replacement for conventional nuclear power stations, according to new research.

Researchers identify cause of inherited form of extreme nearsightedness Posted: 02 Oct 2015 07:33 AM PDT 'Why, Grandma, what big eyes you have!' Though similar in appearance, the hidden cause of those big eyes Little Red Riding Hood notices in Grimms' fairy tale has nothing to do with the hidden cause of enlarged eyeballs in buphthalmia, a genetic mechanism causing this devastating eye disease which has now been uncovered by researchers. Patients afflicted are severely myopic, or nearsighted.

In an international collaboration, researchers have now devised a new method which will help determine this dipole moment more accurately than ever before.

From nuclear research to surgery technology Posted: 02 Oct 2015 05:23 AM PDT A JRC invention initially stemming from its research in the nuclear sector will soon be used by hospitals for minimally-invasive robotic surgery. TELELAP ALF-X is an advanced multi-port robotic system that will empower surgeons with new technologies such as eye-tracking and haptics, allowing them eye-control of the camera and touch sensation during surgery. Hospitals will be able use the most advanced technology while running at low operational costs, as the system can use current surgical instruments.

New biodegradable materials could replace plastic bags Posted: 02 Oct 2015 05:23 AM PDT As England gets set to start paying for plastic bags, researchers are making inroads into developing alternative biodegradable materials that could potentially replace fossil fuel derived polyethylene single-use carrier bags in the future.

Signals from empty space Posted: 02 Oct 2015 05:23 AM PDT What are the properties of the vacuum, the absolute nothingness? So far, physicists have assumed that it is impossible to directly access the characteristics of the ground state of empty space. Now, a team of physicists has succeeded in doing just that. They demonstrated a first direct observation of the so-called vacuum fluctuations by using short light pulses while employing highly precise optical measurement techniques.

Fruit fly research reveals genetic mechanisms of dietary sugar sensing Posted: 02 Oct 2015 05:23 AM PDT A sugar sensing regulatory network, which is composed of several genes, has been identified by researchers. Deregulation of this sugar sensing network leads to severely disturbed energy metabolism. The new insight gained in this study may also benefit research into human metabolic diseases such as diabetes.

Studying cardiac arrhythmias in nematodes Posted: 02 Oct 2015 05:23 AM PDT A simple model using the nematode Caenorhabditis elegans has been developed that can be used to test substances for treating genetically-mediated cardiac arrhythmias. They used the nematode feeding apparatus for this purpose, a rhythmically active muscle pump that resembles the muscle cells in the mammalian heart. This could be an important step on the road to personalized treatment.
