Researchers probe properties of the new material, say better for micro- and nanodevices.
Air travel these days has become pretty smooth, with passengers feeling very little vibrations while seated in the cabin. Engineers install palm-sized devices on the aircraft wings and cabin windows to dampen the vibrations from the huge aircraft turbine engines and the surrounding atmosphere. These devices are made of piezoelectric materials, which generate a large vibration-cancelling force when an electric signal is applied.
Researchers have explained how the electronic properties and atomic vibrations of uranium are linked.

Researchers develop thread-based sensors to detect changes in metabolite levels in sweat.
Metabolism — or the processing and utilisation of energy resources to sustain life — results in a number of by-product molecules called metabolites. Medical practitioners measure the concentration of these molecules in body fluids such as blood, urine, sweat and saliva to test whether the body is functioning normally. While biannual check-ups suffice for the regular population, people with chronic diseases need to monitor their medical conditions constantly.
