Tech Xplore / AI headphones automatically learn who you're talking to—and let you hear them better
Holding a conversation in a crowded room often leads to the frustrating "cocktail party problem," or the challenge of separating the voices of conversation partners from a hubbub. It's a mentally taxing situation that can ...
Phys.org / How oxygen first reached Earth's oceans
For roughly 2 billion years of Earth's early history, the atmosphere contained no oxygen, the essential ingredient required for complex life. Oxygen began building up during the period known as the Great Oxidation Event (GOE), ...
Phys.org / Black hole ejects matter at 20% light speed in sun-like magnetic event
An international team of astronomers, led by SRON, has observed a sudden outburst of matter near the supermassive black hole NGC 3783 at speeds reaching up to 20% of the speed of light. During a 10-day observation, mainly ...

Phys.org / Like living cells, oil-in-water droplets form 'arms' in response to their environment
Oil-in-water droplets respond to chemical cues by forming arm-like extensions that resemble filopodia, which are used by living cells to sense and explore their environment.
Phys.org / From light to logic: Ultrafast quantum switching in 2D materials
Scientists from the Indian Institute of Technology Bombay have found a way to use light to control and read tiny quantum states inside atom-thin materials. The simple technique could pave the way for computers that are dramatically ...
