A simple trick just made tiny lasers more powerful than ever

For years, engineers have sought better ways to build tiny, efficient lasers that can be integrated directly onto silicon chips, a key step toward faster, more capable optical communications and computing. Today’s commercial lasers are mostly made from III-V semiconductors grown on specialized substrates — a process that makes them…

Scientists discover forgotten particle that could unlock quantum computers

Quantum computers have the potential to solve problems far beyond the reach of today’s fastest supercomputers. But today’s machines are notoriously fragile. The quantum bits, or “qubits,” that store and process information are easily disrupted by their environment, leading to errors that quickly accumulate. One of the most promising approaches…

Scientists found the missing nutrients bees need — Colonies grew 15-fold

A new study led by the University of Oxford in collaboration with Royal Botanic Gardens Kew, University of Greenwich, and the Technical University of Denmark could provide a cost-effective and sustainable solution to help tackle the devastating decline in honeybees. An engineered food supplement, designed to provide essential compounds found…

Most of Earth’s species came from explosive bursts of evolution

The British evolutionary biologist JBS Haldane is said to have quipped that any divine being evidently had ‘an ordinate fondness for beetles’. This bon mot conveyed an important truth: the ‘tree of life’ – the family tree of all species, living or extinct – is very uneven. In places, it…

Are we accidentally broadcasting our location to alien civilizations?

If an extraterrestrial intelligence were looking for signs of human communications, when and where should they look? In a new study, researchers at Penn State and NASA’s Jet Propulsion Laboratory in Southern California analyzed when and where human deep space transmissions would be most detectable by an observer outside our…

Con l’inquinamento luminoso gli uccelli cantano più a lungo – News – Ansa.it

A causa dell’inquinamento luminoso gli uccelli cantano più a lungo, prolungando i loro vocalizzi mediamente di 50 minuti al giorno. Lo dimostra l’ampio studio su scala mondiale pubblicato sulla rivista Science dai ricercatori della Southern Illinois University Carbondale e della Oklahoma State University, negli Stati Uniti. Lo smog luminoso generato…
