A star caught feeding on its companion has finally revealed the source of some of the galaxy’s most mysterious repeating signals. An international research team led by scientists at the University of Sydney has uncovered the strongest evidence yet explaining the origin of a puzzling type of cosmic signal. Their work has also revealed a [...]

Depois de vários meses de testes, o avião supersónico X-59 prepara-se para novos voos mais ambiciosos. A equipa da NASA espera que a aeronave ultrapasse a velocidade do som, a mais de 13 mil metros de altitude, já no início de junho.

L'evoluzione umana continua a operare in modo attivo sull'altopiano tibetano, a oltre 3.500 metri di altitudine. Un'indagine condotta su 417 donne native ha rivelato che il successo riproduttivo è legato a specifiche mutazioni fisiologiche che ottimizzano la gestione dell'ossigeno in condizioni di aria rarefatta. Le donne con la maggiore fitness evolutiva non presentano un aumento dei globuli rossi, dinamica che renderebbe il sangue pericolosamente viscoso, ma mostrano un'elevata saturazione di ossigeno e un'emoglobina nella media. Questa efficienza è supportata da modifiche strutturali dell'apparato cardiocircolatorio, come ventricoli sinistri più ampi e un flusso ematico accelerato verso i polmoni, consentendo di trasmettere alla progenie tratti genetici mirati alla sopravvivenza in ambienti estremi.

Thousands of electric vehicles in Waymo’s autonomous robotaxi fleet may eventually give up their used batteries for a very different purpose—contributing up to hundreds of megawatt-hours of stationary energy storage to local power grids.

That prospect comes from a “strategic supply agreement” announced by Waymo and B2U Storage Solutions on June 4. B2U has been repurposing thousands of used batteries from various electric vehicles by installing them in large stationary energy storage projects. Such energy storage facilities can capture excess renewable energy during low demand periods and release such energy when local power grids are experiencing peak demand periods.

“Our business is getting the full residual value out of electric vehicle batteries after they're no longer suitable for automotive use,” Freeman Hall, CEO of B2U Storage Solution, told Ars. “Waymo puts a lot of miles on EVs and their model is expanding rapidly, and so we're just very pleased and honored to be able to work with them.”

D'estate lo facciamo tutti: bicchiere ghiacciato e via. Ma la scienza ha qualcosa da dire sull'acqua fredda — e non è quello che pensi. Alcuni studi la collegano al mal di testa, altri alla digestione difficile. C'è però un contesto in cui fa davvero bene. La temperatura giusta? Probabilmente già ce l'hai nel rubinetto.

On today’s really quick episode of Quick Charge, we’re doing a crossover episode with Mike Bush from Marketscale’s Hammer Down podcast and explore the business of freight and logistics, how to get involved, and what the future might hold for more efficient, fossil-free trucking.
