Engineers develop stickers that can see inside the body

Ultrasound imaging is a safe and noninvasive window into the body's workings, providing clinicians with live images of a patient's internal organs. To capture these images, trained technicians manipulate ultrasound wands ...

How eye imaging technology could help robots and cars see better

Even though robots don't have eyes with retinas, the key to helping them see and interact with the world more naturally and safely may rest in optical coherence tomography (OCT) machines commonly found in the offices of ophthalmologists.

A screw that can halve the level of perceived sound

Could noisy neighbors become a thing of the past? If you are disturbed by crashes, bangs, and muffled voices from next door, then you are not alone, but a Malmö University researcher thinks the answer is as simple as a screw.

Scientists use smartphone gyroscopes to sync time across devices

Skoltech researchers have designed a software-based algorithm for synchronizing time across smartphones that can be used in practical tasks requiring simultaneous measurements. This algorithm can essentially help turn several ...

Longitudinal wave

Longitudinal waves are waves that have same direction of oscillations or vibrations along or parallel to their direction of travel, which means that the oscillations of the medium (particle) is in the same direction or opposite direction as the motion of the wave. Mechanical longitudinal waves have been also referred to as compressional waves or compression waves.
