Si accendono i riscaldamenti, il vademecum – Notizie – Ansa.it

In attesa della progressiva scomparsa delle caldaie a gas dal 2029 come indicato da Bruxelles e con i depositi quasi pieni (l’Italia è quasi al 95%) parte la stagione del riscaldamento ma sempre con una certa preoccupazione. Le bollette del gas degli ultimi anni hanno infatti ‘raffreddato’ l’abitudine sacrosanta degli…

Alarming surge in memory problems among young adults

Self-reported cognitive disability among U.S. adults increased from 5.3% to 7.4% over the past decade. Rates nearly doubled for younger adults ages 18 to 39. The steepest increases occurred among people with lower incomes and less education. American Indian and Alaska Native adults reported the highest overall rates. Researchers urge…

The bold idea that spacetime doesn’t exist

The question of whether spacetime truly exists should not be particularly controversial or even conceptually difficult once we understand what is meant by “spacetime,” “events,” and “instants.” Believing that spacetime is a real, physical entity is no more defensible than believing in the old idea of a celestial sphere. Both…

JWST captures stunning 3D view of a planet’s scorching atmosphere

Astronomers have produced the first three-dimensional map of a planet outside our solar system, revealing distinct temperature regions, including one so hot that water vapor breaks apart. The findings appear in Nature Astronomy, published October 28, 2025. Led by researchers at the University of Maryland and Cornell University, the study…

Quantum light breakthrough could transform technology

High-order harmonic generation (HHG) is a process that transforms light into much higher frequencies, allowing scientists to explore areas of the electromagnetic spectrum that are otherwise difficult to reach. However, generating terahertz (THz) frequencies using HHG has remained a major obstacle because most materials are too symmetrical to support this…

This artificial leaf turns pollution into power

“If we’re going to build a circular, sustainable economy, the chemical industry is a big, complex problem that we must address,” said Professor Erwin Reisner from Cambridge’s Yusuf Hamied Department of Chemistry, who led the research. “We’ve got to come up with ways to de-fossilize this important sector, which produces…

A warming Earth could accidentally trigger a deep freeze

For most of Earth’s history, scientists have viewed the slow breakdown of silicate rocks as the planet’s main natural thermostat. In this process, rainwater absorbs carbon dioxide (CO2) from the air, lands on exposed rocks, and gradually dissolves them. The carbon and calcium released eventually flow into the oceans, where…

Frontale auto-autobotte pompieri, un morto e sei feriti – Notizie – Ansa.it

L’incidente è avvenuto lungo la provinciale 671 della Valle Seriana, nel tratto…

Scientists uncover what delayed Earth’s oxygen boom for a billion years

The arrival of oxygen in Earth’s atmosphere marked a defining moment in the planet’s history, transforming it into a world capable of supporting complex life. This major shift, known as the Great Oxidation Event (GOE), took place approximately 2.1 to 2.4 billion years ago. However, oxygenic photosynthesis — produced by…

Woody Allen verso i 90 anni con un film in cantiere – Notizie – Ansa.it

La vecchiaia con gli acciacchi che aumentano, il futuro che include sempre il lavoro e forse un cinquantunesimo film girato stavolta a Madrid: un Woody Allen in vena di riflessioni si prepara al 90esimo compleanno che non festeggerà nella data fatidica del 30 novembre perchè “non sono più 25, non…
