Pure water is an almost perfect insulator. Yes, water found in nature conducts electricity – but that’s because of the impurities therein, which dissolve into free ions that allow an electric current to flow. Pure water only becomes “metallic” – electronically conductive – at extremely high pressures, beyond our current abilities to produce in a

The “little helicopter that could” has done it again. NASA’s Ingenuity helicopter on Mars, a tissue-box-sized rotorcraft that landed with the Perseverance rover in February, completed its 10th flight over the red planet on Saturday. Each Ingenuity flight has been more daring than the last. So Saturday’s flight was likely the helicopter’s riskiest yet: If

Scientists on Thursday unveiled the most exhaustive database yet of the proteins that form the building blocks of life, in a breakthrough observers said would “fundamentally change biological research”. Every cell in every living organism is triggered to perform its function by proteins that deliver constant instructions to maintain health and ward off infection. Unlike

‘Magic angle’ twisted trilayer graphene doesn’t only have an impressively exotic name, it might be a particularly rare type of superconductor, according to new research – one that could be useful everywhere from medical equipment to quantum computers. Scientists are finding that stacking single-atom layers of graphene on top of each other at slightly different
