When disordered magnetic materials are cooled to just the right temperature, something interesting happens. The spins of their atoms ‘freeze’ and lock into place in a static pattern, exhibiting cooperative behavior not usually displayed.   Now for the first time, physicists have seen the opposite. When fractionally heated, the naturally occurring magnetic element neodymium freezes,

Australian scientists have created the world’s first-ever quantum computer circuit – one that contains all the essential components found on a classical computer chip but at the quantum scale.    The landmark discovery, published in Nature today, was nine years in the making.  “This is the most exciting discovery of my career,” senior author and

The Siberian tundra could disappear by the year 2500, unless greenhouse gas emissions are dramatically reduced.  Even in the best-case scenarios, two-thirds of this landscape – defined by its short growing season and cover of grasses, moss, shrubs and lichens – could vanish, leaving behind two fragments separated by 1,553 miles (2,500 kilometers), scientists recently predicted.

Experts are warning that the Eastern US should prepare for another barrage of tropical storms this year. The 2022 Atlantic hurricane season is likely to be more active than average for the seventh year in a row, according to the latest prediction from the National Oceanic and Atmospheric Administration (NOAA).    There is a 70 percent chance

Fast radio bursts are one of the biggest cosmic mysteries of our time. They’re extremely powerful but extremely brief explosions of electromagnetic radiation in radio wavelengths, discharging in milliseconds as much energy as 500 million Suns.   For years, scientists puzzled over what could be causing these brief outbursts, detected in galaxies millions to billions
