Thermometers here reached a low of -89.2°C in July 1983, the lowest air temperature ever directly recorded. It is also one of the driest places on Earth, receiving around 20 millimetres of ...

6 天之前 · The odd superconductivity found in layered graphene may bring us closer to understanding room-temperature superconductors By Karmela Padavic-Callaghan 5 February 2025

2024年12月5日 · Environment We finally have an explanation for 2023’s record-breaking temperatures. A decline in low-lying cloud cover means Earth is absorbing more solar radiation, which could explain 0.2°C ...

2024年12月12日 · The average global surface temperature during 2025 will be between 1.29°C and 1.53°C – and most likely 1.41°C – above the pre-industrial average, according to a forecast by the Met Office ...

2024年5月7日 · A matter of weeks later, news broke of another substance called LK-99 that apparently worked at both room temperature and ambient pressure. Alas, all that glitters is not gold – both claims have ...

There are two types: low-temperature, or conventional, superconductivity, which generally only occurs within a few degrees of absolute zero and is well-understood by theoretical physicists; and ...

2025年1月22日 · Physics Twisted crystals show hints of a new kind of superconductivity. A double layer of tungsten diselenide behaves as a superconductor at very low temperatures, which could suggest a new route ...

2010年2月17日 · The lowest temperature ever measured in the solar system was on the Moon. Last year, NASA’s Lunar Reconnaissance Orbiter measured temperatures as low as −240°C in permanently shadowed craters ...

2020年3月4日 · In winter with the heating on, the radiators produce convection currents. Colder, denser air falls, displacing warmer air. If the thermostat records 20°C, the temperature at floor level will be ...

2025年1月10日 · Environment 2024 confirmed as first year to breach 1.5°C warming limit. Scientists warn efforts to limit the long-term temperature rise to 1.5°C will fail as data confirms 2024 was the hottest ...
