(Phys.org)—A team of researchers at Duke University has found a way to solve what is known as the cocktail party problem, getting a computer to pick out different human voices among multiple speakers in a single room. In ...
During a solar eclipse, the Moon's passage overhead blocks out the majority of the Sun's light and casts a wide swath of the Earth into darkness. The land under the Moon's shadow receives less incoming energy than the surrounding ...

Quantum information platforms are based on qubits that talk to each other and photons (optical and microwave) are the carrier of choice—to date, to transfer quantum states between qubits. However, in some solid-state systems, ...
Acoustic tweezers that can move single cells in three dimensions using surface acoustic waves without touching, deforming or labeling the cells are possible, according to a team of engineers.

(Phys.org) —In a typical man-made sonar system, pulses of sound emitted by the projector bounce off hidden objects underwater. The echoes are then detected by the receiver to infer the location and size of the hidden objects.
Having a neighborly chat improves seed germination, finds research in BioMed Central's open access journal BMC Ecology. Even when other known means of communication, such as contact, chemical and light-mediated signals, are ...
