Superconductivity was first seen in metals cooled down to close to absolute zero. But after exhausting every metal on the periodic table, the critical temperature at which the metal transitions to superconductivity never budged far from those extremely low temperatures.
That changed dramatically with the development of cuprate superconductors, copper-containing ceramics that could superconduct in liquid nitrogen—still very cold (138K or −135°C), but relatively easy to achieve. But progress has stalled, in part because we don't have a solid theory to explain superconductivity in these materials.
Now, taking advantage of the fact that we do understand what's going on in superconducting metals, a German research team has reached a new record critical temperature: 203K, or -70°C, a temperature that is sometimes seen in polar regions. The material they used, however, isn't a metal that appears on the periodic table. In fact, they're not even positive they know what the material is,...
Microsoft and Sony still have not given any details about the cost of their impending consoles. However, they are extensively anticipated to be more costly than their present-gen models.
Hackers attack the supercomputers of the UK, Germany, and Switzerland, and "infections" included cryptocurrency-mining spyware.
Scientists got an idea to make shimmery chocolate during coffee break. It was wondering for them to make colored chocolate and select it as research topic.
Good to see some significant progress. Although the extreme measures are self defeating in the ultimate goal, some interesting information is gleamed from these tests.
