Researchers from four universities in Germany have created the coldest temperature ever recorded in a lab—38 trillionths of a degree warmer than absolute zero to be exact, according to their new work, recently published in the journal Physical Review Letters.
The bone-chilling temperature only persisted for a few seconds at the University of Bremen's Center for Applied Space Technology and Microgravity, but the breakthrough could have longstanding ramifications for our understanding of quantum mechanics.
That's because the closer we get to absolute zero—the lowest possible temperature that we could ever theoretically reach, as outlined by the laws of thermodynamics—the more peculiarly particles, and therefore substances, act. Liquid helium, for instance, becomes a "superfluid" at significantly low temperatures, meaning that it flows without any resistance from friction. Nitrogen freezes at -210 degrees Celsius. At cool enough temperatures, some particles even take on wave-like characteristics.

But none of those winners are women. Expand your storage capacity while keeping equipment safe and secure. Jupiter, Saturn, Uranus, or Neptune may have sent the Earth-sized planet barreling toward deep space. Canon has been making top-tier cameras year after year, but how do you pick the right camera for you? With its low-impact combination of strength and cardio, a rowing machine is a must-have for home workouts. These are the best magnetic, air, and water-resistance models on the market in a variety of budgets.
