Gli Usa hanno schierato la portaerei Nimitz nei Caraibi – Notizie – Ansa.it

Il Comando Sud degli Stati Uniti (Southcom) ha comunicato l’arrivo ieri nei Caraibi della portaerei a propulsione nucleare Nimitz e del relativo gruppo d’attacco. L’annuncio coincide con l’intensificarsi della campagna di pressione dell’amministrazione di Donald Trump contro Cuba e con l’incriminazione, sempre ieri, dell’ex presidente Raúl Castro per l’abbattimento di…

Physicists finally solve the strange mystery of “breathing” lasers

An international team of researchers, including a scientist from Aston University, has developed a new mathematical framework that explains the strange behavior of so called “breather” laser pulses. The breakthrough unites two very different types of laser dynamics under a single model for the first time. Ultrafast lasers generate incredibly…

Flotilla, Carotenuto e Mantovani arrivati in Italia – Notizie – Ansa.it

  Il deputato del M5S Dario Carotenuto ed il giornalista del Fatto Quotidiano Alessandro Mantovani, che erano a bordo di una delle navi
della Flotilla intercettate dagli israeliani, sono rientrati in Italia. Sono sbarcati, all’aeroporto di Fiumicino, da un volo di linea da Atene, accolti, tra gli altri, con abbracci, dai…

Jupiter’s lightning may be 100x more powerful than Earth’s

Jupiter is famous for its enormous storms, some of which have been raging for centuries. Now, scientists have discovered that these massive tempests can also generate lightning far more powerful than anything typically seen on Earth. Using data from NASA’s Juno spacecraft, researchers at the University of California, Berkeley found…

Scientists discover the nutrient that can supercharge cellular energy

Mitochondria are often called the power plants of the cell because they generate the energy the body needs to function. These tiny structures constantly adjust their activity depending on how much energy cells require. Scientists have long known that nutrients influence this process, but exactly how cells sense and respond…

Forte scossa di terremoto poco dopo l’alba a Napoli – Notizie – Ansa.it

Una forte scossa di terremoto, di magnitudo 4.4 e una profondità di 3 chilometri, è stata distintamente avvertita a Napoli poco dopo l’alba, alle 5.51, e nei vicini comuni dell’area flegrea e occidentale. Si tratta di una delle scosse più elevate da quando è riesploso il bradisismo in quell’area e che…

MIT scientists discover amino acid that helps the gut heal itself

MIT researchers have discovered that a naturally occurring amino acid found in many protein-rich foods may help the intestine repair itself after damage. In a new study, scientists found that cysteine can activate an immune response that boosts intestinal stem cells and helps regenerate tissue in the small intestine. The…

UNESCO warns a tsunami in the Mediterranean is inevitable

The Mediterranean sea is widely perceived as having a low tsunami risk. History and recent modelling technology have demonstrated that destructive waves have already hit the French coast and could do so again. The results of a project carried out in Nice and along the French Riviera show why anticipation…

Scientists solve 320-million-year mystery of reptile bone armor

Our bones did not begin deep inside the body. They started in the skin, not long after the first complex animals took shape. Ever since, skin bones have remained a recurring motif in evolution. Yet we still know surprisingly little about them. Why do they keep reappearing in groups as…

New quantum sensor could count individual photons and hunt dark matter

Researchers in Finland have achieved a major advance in ultra-sensitive measurement technology by detecting an amount of energy smaller than one zeptojoule, less than a trillionth of a billionth of a joule. The breakthrough could improve quantum computing technology, support the search for dark matter, and eventually make it possible…
