A version of this story appeared in Science, Vol 378, Issue 6624.Download PDF SLAVUTYCH, UKRAINE—In one of the last acts of camaraderie in a fractured nation, Soviet workers from the Baltics to the Caucasus converged on a pine forest in the late 1980s to build a Ukrainian city from scratch. Slavutych was a new home …

Banner Image: A powerful green laser helps visualize aerosol plumes from a toilet as it is flushed. (Credit: Patrick Campbell/CU Boulder) Thanks to new research from CU Boulder, scientists are seeing the impact of flushing in a whole new light — and now the world can, too. Using bright green lasers and camera equipment, a …

Artist rendering. Credit: Anyu Lei and Jing Chen, Nanjing University School of Arts The mysteries of the cosmos continue to amaze astronomers, and each new sighting is a chance to deepen – or shake up – our understanding of the universe. In the December 7 issue of the journal Nature, an international team of astrophysicists …

This is the third in a series of articles exploring the birth of quantum physics. Light is a paradox. It is associated with wisdom and knowledge, with the divine. The Enlightenment offered the light of reason as the guiding path to truth. We have evolved to identify visual patterns with great precision – to distinguish …

(Top panel) Fit to Doppler parameter distribution and Lyman-alpha forest column density distribution function at z=0.1 assuming a maximum contribution of dark photon heating to linewidths. The contours show the projection of the 68% and 95% intervals for the mass and the mixing parameter of the dark photon. Colors correspond to different assumptions about the …

For the first time, physicists have shown that light travels forwards and backwards simultaneously in time. The new technique could help scientists improve quantum computing and understand quantum gravity. By splitting a photon, or a packet of light, using a special optical crystal, two independent teams of physicists have achieved what they describe as a …

A ring of superconducting qubits can host “bound states” of microwave photons, where photons tend to clump together on neighboring qubit sites. Credit: Google Quantum AI The researchers used a quantum processor to make the microwave photons unusually sticky. They coaxed them into clumping together into bound states, then discovered that these photon clusters survived …

Reconstruction of the Kap København formation two million years ago at a time when the temperature was significantly warmer than far northern Greenland today. 1 credit Two-million-year-old DNA has been identified for the first time, opening a new “game-changing” chapter in evolutionary history. Microscopic fragments of environmental DNA have been found in Ice Age sediments …
