Scientists say we’ve been treating Alzheimer’s all wrong

Alzheimer’s disease (AD) remains one of the most pressing global health challenges, especially as aging populations continue to grow. The condition steadily erodes memory and thinking abilities, deeply affecting daily life. New treatments, including monoclonal antibodies such as lecanemab and donanemab, have offered some optimism by slowing cognitive decline. However,…

A common nutrient could supercharge cancer treatment

Researchers at the University of Chicago have uncovered a surprising new role for zeaxanthin, a plant-based compound best known for supporting eye health. According to findings published in Cell Reports Medicine, this common carotenoid may also help the immune system fight cancer by enhancing the activity of key immune cells.…

Gravitational waves may be hidden in the light atoms emit

Gravitational waves are tiny ripples in spacetime created by powerful cosmic events such as colliding black holes. Until now, scientists have detected them by measuring extremely small changes in distance using huge instruments that stretch for kilometers. A new theoretical study, accepted for publication in Physical Review Letters, suggests a…

This superconductivity dies then comes back to life

Researchers have uncovered and explained an unusual form of superconductivity that only appears under extremely strong magnetic fields. The work, led in part by Rice University physicist Andriy Nevidomskyy, was published in Science and describes how uranium ditelluride (UTe2) forms a distinctive superconducting halo when exposed to intense magnetic conditions.…

These cheap solar cells work better because they’re flawed

Lead-halide perovskites, even when packed with impurities and structural flaws, are remarkably effective at turning sunlight into electricity. Their performance is now approaching that of silicon-based solar cells, which have long dominated the industry. In a recent study published in Nature Communications, researchers at the Institute of Science and Technology…

This new chip could slash data center energy waste

As data centers consume more energy to support growing digital demands, engineers at the University of California San Diego have introduced a new chip design that could make powering graphics processing units (GPUs) more efficient. The innovation focuses on a key function in electronics: converting high voltages into the lower…

Scientists think dark matter might come in two forms

Sometimes, not seeing something can be just as important as detecting it. That idea is at the heart of a new study published in the Journal of Cosmology and Astroparticle Physics (JCAP). The research suggests scientists may not need to find identical signals everywhere in the universe to understand dark…

‘Gli Aeroporti Ue a rischio carburante entro tre settimane’ – Notizie – Ansa.it

Gli aeroporti europei rischiano una carenza “sistemica” di carburante per aerei se lo Stretto di Hormuz non verrà completamente riaperto entro tre settimane. Aci Europe, che rappresenta gli aeroporti dell’Ue, ha affermato che le riserve di carburante per aerei si stanno esaurendo mentre “l’impatto delle attività militari” sta mettendo ulteriormente…

Frana in Molise, riaperta la linea ferroviaria adriatica – Notizie – Ansa.it

Riaperta dalle 6 di questa mattina la linea ferroviaria adriatica, che era stata chiusa nel tratto fra Termoli e Montenero di Bisaccia in seguito alla frana di Petacciato. La circolazione, spiega Trenitalia sul proprio sito, “è in graduale ripresa, dopo l’intervento dei tecnici di Rfi”. Nel corso della giornata di…

Scientists finally uncover why promising cancer drugs keep failing

For more than a decade, scientists have tested a group of cancer drugs known as BET inhibitors with high hopes. The science behind them seemed strong. Many tumors rely on oncogenes that are switched on with help from “Bromo- and Extra-Terminal domain” (BET) proteins, so blocking those proteins was expected…

Goodbye colonoscopy? New stool test detects 90% of colorectal cancers

Colorectal cancer is the second leading cause of cancer-related deaths worldwide. When caught early, it is often highly treatable. However, colonoscopies — the primary screening method used today — can be costly and uncomfortable, which discourages many people from getting tested on time. Researchers at the University of Geneva (UNIGE)…
