Dark matter detector observes rarest event ever recorded

How do you observe a process that takes more than one trillion times longer than the age of the universe? The XENON Collaboration research team did it with an instrument built to find the most elusive particle in the universe—dark ...

Spin flipper upends protons

Protons spin. It's an intrinsic property that can affect experiments at accelerators that use beams of protons. Yet flipping proton spins could offer insights into nuclear physics experiments that study the first moments ...

Travel through wormholes is possible, but slow

A Harvard physicist has shown that wormholes can exist: tunnels in curved space-time, connecting two distant places, through which travel is possible.

Researchers witness the emergence of a new gene in the lab

How do new genes appear? For more than a century, researchers have thought that, from time to time, new gene functions evolved after cells accidentally made a copy of one of their existing genes. According to this theory, ...

Tuneable reverse photochromes in the solid state

Photochromes are dyes that change their colour depending on the light they receive. When light is switched off they can either remain in their photoinduced state (P-type photochromes) or turn back to their original state ...
