New physics at stake? Deviation from the standard model of physics confirmed

An ultraprecise measurement of spinning muons, heavier cousins of electrons, in magnetic fields has strengthened a 20 year old signal of new physics, potentially yielding the first sign of new fundamental particles or…

ALMA Discovers Rotating Infant Galaxy with Help of Natural Cosmic Telescope

Using the Atacama Large Millimeter/submillimeter Array, astronomers at the Cosmic Dawn Center at UCPH/DTU found a rotating baby galaxy 1/100th the size of the Milky Way at a time when the Universe was only 7% of its…

Abrupt ice age climate changes behaved like cascading dominoes

Throughout the last ice age, the climate changed repeatedly and rapidly during so-called Dansgaard-Oeschger events, where Greenland temperatures rose between 5 and 16 degrees Celsius in decades.
