An ordinary laptop solved a problem thought to require a quantum computer

Physicists have used an ordinary computer, advanced mathematics, and specialized software to solve a difficult quantum physics problem that had been described as beyond the reach of classical machines. The work was carried out by researchers at the Center for Computational Quantum Physics (CCQ) at the Simons Foundation’s Flatiron Institute,…

Migliaia di persone protestano nel centro di Nuova Delhi – Notizie – Ansa.it

Migliaia di persone stanno manifestando nel centro di New Delhi: lo ha constatato l’ANSA sul posto. I dimostranti sfilano nella zona di Jantar Mantar chiedendo le dimissioni del ministro dell’Istruzione indiano, Dharmendra Pradhan, dopo una presunta fuga di informazioni sulle domande del test di ingresso alla facoltà di Medicina svoltosi…

Scientists discover a protein that protects the brain from Alzheimer’s damage

Alzheimer’s disease and several other neurodegenerative disorders are linked to a damaging change in tau, a protein that normally helps support the internal structure of nerve cells. Under healthy conditions, tau stabilizes microtubules, the filament-like structures that help maintain neuronal shape and function. In disease, however, tau can twist into…

UCLA scientists develop mineral sunscreen without the chalky white cast

UCLA scientists have created a mineral sunscreen formula that leaves far less of the pale, chalky residue that often discourages people from using sun protection every day. Dermatologists have long recommended daily sunscreen use to reduce exposure to ultraviolet radiation. Too much ultraviolet radiation is the leading preventable cause of…

Scientists found two powerful new ways to destroy forever chemicals

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are testing two technologies designed to destroy per- and polyfluoroalkyl substances (PFAS), a vast family of industrial chemicals known for resisting natural and conventional breakdown processes. The first approach uses hydrodynamic cavitation, which creates and collapses tiny vapor bubbles in contaminated water. The second…
