The possibilities for dark matter have just shrunk — by a lot
The LZ dark matter experiment has ruled out weakly interacting massive particles, or WIMPs, with a wide range of properties.

The world’s fastest microscope makes its debut
Using a laser and an electron beam, the microscope can snap images of moving electrons every 625 quintillionths of a second.

Zigzag walls could help buildings beat the heat
A corrugated exterior wall reflects heat to space and absorbs less heat from the ground, keeping it several degrees cooler than a flat wall.

Dark matter experiments get a first peek at the ‘neutrino fog’
The hint of fog marks a new way to observe neutrinos, but points to the beginning of the end for this type of dark matter detection.

A new element on the periodic table might be within reach
Scientists made the known element 116 with a beam of titanium atoms, a technique that could be used to make the undiscovered element 120.

Something weird is happening to Earth’s inner core
A new study claims to confirm that the inner core is now rotating more slowly than it was over a decade ago, but some researchers remain skeptical.
