James Webb reveals a barred spiral galaxy shockingly early in the Universe

A research team led by Daniel Ivanov, a physics and astronomy graduate student in the Kenneth P. Dietrich School of Arts and Sciences at Pitt, has identified a strong candidate for one of the earliest known spiral galaxies with a stellar bar. These bright, elongated structures can strongly influence how…

A lost moon may have created Titan and Saturn’s rings

New research suggests that Saturn’s brilliant rings and its largest moon, Titan, may share a violent past shaped by collisions between moons. Although NASA’s Cassini spacecraft transformed our understanding of Saturn during its 13 year mission, it also uncovered new puzzles, including the surprisingly young age of Saturn’s rings and…

Iron outperforms rare metals in stunning chemistry advance

Photocatalysts are materials that absorb light and use that energy to drive chemical reactions. In organic synthesis, metal based photocatalysts are especially valuable because they are durable and can be customized. By adjusting the ligands attached to the central metal atom, chemists can fine tune how the catalyst behaves. Many…

I pulcini collegano suoni e forme, come gli esseri umani – News – Ansa.it

Anche i pulcini, proprio come gli esseri umani, collegano specifici suoni, come le parole inventate ‘bouba’ e ‘kiki’, con forme astratte rispettivamente più arrotondate o più appuntite. Lo dimostra lo studio dell’Università di Padova pubblicato sulla rivista Science e condotto con pulcini di soli tre giorni. I risultati indicano che…

New engine uses the freezing cold of space to generate power at night

Engineers at the University of California, Davis have created a device that produces mechanical power at night by taking advantage of the temperature difference between the warmth of the Earth and the extreme cold of outer space. The system could eventually help ventilate greenhouses and other buildings without relying on…

Green hydrogen has a hidden problem and scientists may have fixed it

Green hydrogen is widely seen as a key pillar of the global shift away from fossil fuels. Yet making it at scale remains both costly and environmentally complicated. One of the leading production methods, PEM (proton exchange membrane) electrolysis, works especially well when electricity from wind and solar power rises…
