Researchers develop 'acoustic metamaterial' that cancels sound

Boston University researchers, Xin Zhang, a professor at the College of Engineering, and Reza Ghaffarivardavagh, a Ph.D. student in the Department of Mechanical Engineering, released a paper in Physical Review B demonstrating ...

New robot can sense plankton optically and acoustically

Oceanographers and engineers at the University of California San Diego collaborated to modify a common physical oceanography instrument to be able to image zooplankton as it glides through the ocean.

Black widow spiders dial up posture for survival and sex

A new study led by Western University's Natasha Mhatre shows that body dynamics and posture are crucial to how black widow spiders decode the important vibrations that travel through their webs and up their legs. Black widows ...

Good vibrations: Neutrons lend insight into acoustic fracking

Hydraulic fracturing contributes significantly to US energy production. It works by tapping hard-to-reach pockets of oil and natural gas where more traditional drilling methods fall short. However, the process requires large ...

Cold neutrons used in hot pursuit of better thermoelectrics

Thermoelectric devices are highly versatile, with the ability to convert heat into electricity, and electricity into heat. They are small, lightweight, and extremely durable because they have no moving parts, which is why ...
