It seems that biologists know everything about the Alpine hare (Lepus timidus), particularly about its ration. However, the Yakut scientists, Anatoly Pshennikov and Vladimir Pozdnyakov have discovered a previously unknown method the hares employ in wintertime when they suffer from the lack of food.
Forage is scarce in winter in Yakutia. The Alpine hares are content to feed on bushes and young trees. If the distance between the ground and a thin twig is less than a meter, the hare bi
Penn State engineers have developed a low- cost, high-torque rotary motor, based on “smart” materials, that can be configured in a wide range of formats, including one as flat and thin as a CD case.
The inventors say that, in the flat format, the motor could be used to drive changes in the camber of airplane wings or fins, essentially shape-shifting the curvature of the wing or fin surface.
In other formats, the motor could work in tightly integrated spaces where other motors can
Recording and classifying the behaviour of laboratory rodents is a vital part of a wide range of studies ranging from the discovery of new drugs and detection of harmful side-effects to the biological control of agricultural pests. Until now, it has been a lengthy and painstaking task, requiring human observers to judge, count and record. But a new computerised system developed with EUREKAs help has done away with the need for human observers, revolutionising the way labs work around the world.
Jefferson Lab is once again taking center stage, as Lab scientists, engineers and technicians mobilize to provide 81 niobium cavities for 23 cryomodules for the Spallation Neutron Source under construction in Oak Ridge, Tennessee
Thermos bottles usually dont weigh nearly five tons or measure almost 26 feet end-to-end. But these arent run-of-the-mill containers for soup or coffee. Rather, theyre the complex, state-of-the-art supercooled components in which particle beams are
Jefferson Lab’s Free-Electron Laser used to explore the fundamental science of how and why nanotubes form, paying close attention to the atomic and molecular details
Scientists and technologists of all stripes are working intensively to explore the possibilities of an extremely strong and versatile cylinder so tiny that millions — which in bunches look like an ebony snowflake — could fit easily on the tip of a pin. The objects in question are known as carbon nanotubes, first discov
While about 80 percent of people with epilepsy gain significant relief from drug therapy, the remaining 20 percent have seizures that cannot be controlled by medications. Many of these people have a particular type of epilepsy called partial epilepsy. A new study shows that people with partial epilepsy often have seizures controlled by medications for years before their seizures become drug-resistant. The study also found that periods when seizures stopped for a year or more are common in these patie
