Childhood junk food may rewire the brain for life

Children who regularly eat high-fat, high-sugar foods may experience lasting changes in the brain that continue long after their diets improve, according to a new study from University College Cork (UCC). Researchers also found that beneficial gut bacteria and prebiotic fibers could help reduce some of these long-term effects and…

Popular GLP-1 weight-loss drugs like Ozempic slash heart attack and stroke risk

New research suggests that GLP-1 weight loss medications may provide major long-term benefits for heart health in addition to helping people lose weight and manage blood sugar. Researchers at Anglia Ruskin University (ARU) reviewed data from more than 90,000 participants involved in large international clinical trials. Their analysis found that…

Common pesticide linked to hidden brain damage, scientists warn

A recent study has identified a concerning connection between prenatal exposure to chlorpyrifos (CPF), a common insecticide, and lasting changes in brain structure as well as reduced motor function in children and adolescents. These findings, published in the journal JAMA Neurology, offer the first evidence of widespread, enduring impacts on…

Scientists discover hidden weakness shared by hundreds of cancer mutations

Diseases such as cancer and neurodegenerative disorders often begin with genetic mistakes. But even after scientists identify the genes involved, turning that knowledge into effective treatments has remained extremely difficult. Many of these diseases are linked to hundreds of mutations spread across different biological pathways, making it hard to understand…

Scientists discover strange “narwhal” waves that trap light beyond known limits

For decades, shrinking photonic devices has been far more difficult than miniaturizing electronic components. The challenge comes down to physics. Light cannot easily be confined into extremely small spaces because the uncertainty principle links its confinement to its wavelength. In visible and near infrared light, that wavelength can be up…

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…
