The experimental jet was built to kill the sonic boom. First, it has to survive going supersonic.

Days after the U.S. said it would kill a network of ocean monitors, European officials pledged to invest more in their version, calling it a “necessity.”

Un nuovo studio condotto dal team di Elena Rostova ha rivelato che la melatonina svolge un ruolo cruciale nella protezione del DNA dei lavoratori notturni, storicamente soggetti a lesioni genetiche da stress ossidativo. La sostanza penetra nella membrana nucleare e attiva complessi enzimatici responsabili della riparazione cellulare, riducendo drasticamente la rottura dei filamenti del DNA. La scoperta dimostra che la melatonina non regola solo il sonno, ma agisce come un vero e proprio scudo epigenetico per l'organismo.

A newly engineered catalyst overcomes key obstacles that have long limited ammonia as a clean fuel for heavy industry. A newly developed single-atom platinum catalyst can ignite ammonia at about 200°C (392°F) and sustain stable combustion at 1,100°C (2,012°F) while producing very little NOx. The breakthrough could provide carbon-free, high-grade heat for industries such as [...]

Uno studio pubblicato su ScienceDaily e condotto dal team di Burton Craig ha dimostrato che consumare anguria ogni giorno per due settimane apporta significativi benefici cardiovascolari. L'alto contenuto di l-citrullina presente nel frutto viene convertito dai reni in l-arginina, un amminoacido che stimola la produzione di ossido nitrico. Questa molecola funge da potente vasodilatatore naturale, riducendo la pressione arteriosa e migliorando l'elasticità dei vasi. Inoltre, l'accumulo di licopene registrato nei tessuti ha portato a un netto abbassamento della proteina C-reattiva, confermando un marcato effetto antinfiammatorio per l'organismo.

Il rover sovietico Lunokhod 1, sbarcato sulla Luna nel 1970 e ritenuto disperso dal 1971, è stato localizzato grazie alle immagini della sonda LRO della NASA. Sfruttando le nuove coordinate, un team guidato da Tom Murphy ha puntato un raggio laser verso il veicolo dall'osservatorio Apache Point, ricevendo un fortissimo segnale di ritorno dal catadiottro di bordo. Lo specchio passivo, conservatosi in condizioni migliori rispetto a quello del gemello Lunokhod 2, non richiede elettricità e permetterà di misurare la distanza Terra-Luna con precisione millimetrica, aprendo la strada a nuovi test sulla relatività di Einstein e sullo studio del nucleo lunare.

A new MIT-designed lidar chip uses specially engineered antennas to reduce interference and widen the sensor’s field of view. From self-driving cars navigating busy streets to drones surveying disaster zones, lidar has become one of the most important technologies for helping machines perceive the world in three dimensions. By sending out rapid pulses of infrared [...]

L’acqua fangosa del fiume Inasegawa, nella città giapponese di Kamakura, sembrava contenere soltanto la solita popolazione di microbi e amebe. Tra i sedimenti si nascondeva invece un’entità biologica rimasta invisibile fino a oggi: un nuovo virus gigante che si replica violando le regole note della microbiologia. I dettagli della scoperta, coordinata dal virologo Masaharu Takemura […]

NASA engineers completed their final inspection of the Roman telescope's primary mirror and are now preparing to ship the telescope to its Florida launch site.

NASA’s strange-looking X-59 jet is about to reach the milestone it was built for: flying faster than the speed of sound. NASA’s X-59 experimental aircraft is preparing for one of the most important phases of its flight testing program. The next series of flights will include the aircraft’s first journey beyond the speed of sound, [...]

Durante lo scavo di una tomba romana intatta a Carmona, in Spagna, è stato rinvenuto un vaso di vetro che conservava circa cinque litri di un liquido rossastro. Le analisi di laboratorio condotte dal team di José Rafael Ruiz Arrebola hanno rivelato la presenza di polifenoli tipici del vino, escludendo l'acido siringico e dimostrando così che in origine la bevanda era un vino bianco, simile a quelli prodotti oggi nella zona di Jerez. Il liquido si trovava nell'urna cineraria di un uomo, a conferma delle rigide restrizioni di genere della società romana che vietavano il consumo di alcol alle donne. Nonostante la sostanza non sia tossica, i ricercatori ne hanno escluso l'assaggio a causa della contaminazione millenaria con le ossa cremate del defunto.

Tesla announced today that its unsupervised “Robotaxi” service now covers the entire Austin metro area, a significant expansion of its geofenced operating zone.

It’s a notable milestone on paper, but the actual fleet serving this massive area remains tiny — just ~20 active unsupervised vehicles, according to the latest data, a number that has actually been shrinking.

Katelynn Delos Reyes thought she knew what to expect when Typhoon Sinlaku slammed into Saipan in April. As a lifelong resident of the island, Delos Reyes had survived frequent storms, including Super Typhoon Yutu, the second-strongest in U.S. history. Eight years ago, Yutu’s 274-kmph (about 170-mph) winds devastated her village in the southern end of Saipan. Just three years before that, she survived Typhoon Soudelor. But Sinlaku was different. “At the beginning, it was OK. But later on it wasn’t,” said Delos Reyes, who is Chamorro, Indigenous to the Mariana Islands. A few days before it hit the Commonwealth of the Northern Mariana Islands, or CNMI, on April 14, Sinlaku had tropical-storm winds. That made it what is known in the Marianas as a “banana typhoon” because such storms level banana trees but leave others standing. Then over the weekend, the typhoon rapidly intensified by 120 kmph (75 mph) in just 24 hours before becoming a 298-kmph (about 185-mph) monstrosity and the strongest storm on Earth so far this year. Delos Reyes and her family had done what they could to prepare. They boarded up the windows. They bought gallons of drinking water and filled plastic drums to use in the shower and toilet. Then the storm hit, and Delos Reyes grew scared. The winds, which had weakened to 240 kmph (about 150 mph), ripped the wood from a window. Rainwater gushed through the ceiling and soaked their belongings, including Delos Reyes’ mattress. She and her partner, her mother, her…This article was originally published on Mongabay

When most people think about how a bicycle frame is built, they probably imagine sparks flying from a welding torch.

That’s certainly how the vast majority of aluminum bike frames are made. But one British e-bike company is taking a very different approach, and it has more in common with Aston Martin sports cars and aerospace engineering than traditional bicycle manufacturing.
