Spherical bacteria crowd on a plastic surface to form a globular shape with vacancies throughout. When bacteria crowd together and form sticky biofilms, infections can become more dangerous and ...

Researchers have discovered that hedgehogs can hear ultrasound, a surprising ability that could help protect them from cars. Since road traffic kills large numbers of hedgehogs, scientists believe ...

The hedgehog is one of Europe’s most familiar and well-loved wild mammals. Many people encounter them in gardens, hear their snuffling at dusk, or glimpse their spiny shapes moving through the night.

Researchers at the University of Oxford have suggested that ultrasound-repellers could help reduce hedgehog deaths caused by cars. The proposal is based on new findings, published in Biology Letters, ...

Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or ...

Nanosecond pulsed field ablation, which offers potential benefits, such as reduced muscle contraction, may enable procedures to be performed under local anesthesia.To evaluate the 12-month safety and ...

As a noninvasive physical therapy, low-intensity pulsed ultrasound (LIPUS) regulates cell proliferation, apoptosis, inflammation, and angiogenesis through mechanical stress, cavitation effects, and ...

Abstract: High pulse repetition frequency (PRF) radar operation enables Doppler-unambiguous sensing but introduces range ambiguity. This letter introduces a receiver-side sampling diversity framework ...
