(Â鶹ÒùÔº)—A team of researchers at Hong Kong University of Science and Technology has found a way to create a material that is near perfect at preventing sound waves from passing through it. In their paper published in ...
When it comes to protecting the men and women of the armed forces, University of Wisconsin-Madison researcher Nader Behdad focuses his work on an obstacle most people wouldn't associate with combat: the physical limitations ...
A recent study by means of neutron tomography revealed that some forerunners of mammals were already able to hear airborne sound, because these animals already possessed an eardrum at the lower jaw, an impedance-matching ...
Â鶹ÒùÔºicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical ...
The smaller you are, the harder it is not to spin out of control when you jump. Miniscule errors in propulsive force relative to the centre of mass results in most jumping insects - such as fleas, leafhoppers and grasshoppers ...
U.S. wheat growers resist converting to a more profitable method of farming because of ideology – their personal beliefs about organic farming – rather than technical or material obstacles, according to a new study co-authored ...
Wetlands are among the most productive ecosystems on Earth. Yet with increasing urbanization and agricultural expansion, wetlands around the globe are in danger. Better mapping of wetlands worldwide will help in their protection.
Computer chips with superconducting circuits—circuits with zero electrical resistance—would be 50 to 100 times as energy-efficient as today's chips, an attractive trait given the increasing power consumption of the massive ...
A system to allow air- and ground-based robot vehicles to work together, without GPS signals or expensive sensor devices, is being developed by a team at Yonsei University in Korea. This could be used by unmanned vehicle ...
A new, non-invasive technique to track the motion of knee bones in 3D with a very high precision has been presented by researchers in Australia. By employing a single-element ultrasound sensor and a fast image registration ...
