An international team of researchers consisting of scientists from NUST MISIS and TU Dortmund University has developed a technology to study the behavior of orthopedic implants in laboratory conditions as close as possible to the human body. The technology is notable for its ethics: the research can be carried out in vitro -- that is, without involving lab animals. The research article has been published in the Journal of the Mechanical Behavior of Biomedical Materials.

The University of Texas at Arlington has patented a smart seat cushion that uses changes in air pressure to redistribute body weight and help prevent the painful ulcers caused by sitting for long periods of time in a wheelchair. The same technology can be used to create prosthetic liners that adapt their shape to accommodate changes in body volume.

There's quite a story behind calaverite. Apart from its marked impact on the Gold Rush, the mineral has been a headache and a great paradox for crystallographers for decades. The deeper researchers dug into it, the more new questions came up. Scientists from Russia and Germany have succeeded in interlacing all the oddities of calaverite within a simple model, so experimenters can now hunt for the new compound they predicted, AuTe, unknown until now.

Researchers at the Interdisciplinary Nanoscience Center (iNANO) and Department of Chemistry, Aarhus University, have developed both an ingenious, as well as a safe procedure for using the 'rotten egg' smelling and flammable gas, methanethiol, in certain chemical reactions.

Researchers harness naturally occurring nano-structures that grow on liquid metals to develop an ultra-fast water filter.

Purdue University researchers have simulated how over 20 different breast tissue ratios respond to heat given off by MRIs at higher field strengths than available in hospitals today.
