Time for change? Why the UK would be better off with a £1.75 coin

Pennies and cents clog up wallets and pockets.

A warm space station welcome for cool new hardware

Astronaut Christina Koch recently gave a warm welcome to a very cool arrival to the International Space Station: a new piece of hardware for the Cold Atom Lab, an experimental physics facility that chills atoms to almost absolute zero, or minus 459 degrees Fahrenheit (minus 273 degrees Celsius). That’s colder than any known place in the universe. Source: https://phys.org/news/2019-12-space-station-cool-hardware.html…

Why are whales big, but not bigger?

How did whales that feed on tiny prey evolve into the largest creatures on Earth? And why don’t they get even bigger? Source: https://earthsky.org/earth/why-are-whales-big…

Water on giant exoplanets both common and scarce

A new study of the atmospheres of known giant exoplanets suggests that water – an essential ingredient for life – may be common on other worlds in our Milky Way galaxy. At the same, there may be less of it than astronomers once expected. Source: https://earthsky.org/space/water-giant-exoplanets-both-common-and-scarce…

Laser-based prototype probes cold atom dynamics

By tracking the motions of cold atom clouds, astronomers can learn much about the physical processes which play out in the depths of space. To make these measurements, researchers currently use instruments named ‘cold atom inertial sensors’ which, so far, have largely been operated inside the lab. In new work published in EPJ D, a team of physicists at Muquans and…

Cold Moon to prelude Geminid peak

Dark energy: Understanding the mystery force that rules the universe

Dark energy dominates the universe, and could lead it to a cold, bleak end.
