With a powerful laser blast, scientists near a nuclear fusion milestone
A National Ignition Facility experiment spawned nuclear fusion reactions that released nearly as much energy as was used to ignite them.

Windbreaks, surprisingly, could help wind farms boost power output
Wind farm performance could be improved by 10 percent by using low barriers to increase the wind speed directed at the turbines, simulations suggest.

Colliding photons were spotted making matter. But are the photons ‘real’?
Smashups of particles of light creating electrons and positrons could demonstrate the physics of Einstein’s equation E=mc2.

How particle detectors capture matter’s hidden, beautiful reality
Old and new detectors trace the whirling paths of subatomic particles.

A bounty of potential gravitational wave events hints at exciting possibilities
Of about 1,200 possible events, most are probably false alarms, but some could be ripples in spacetime that are especially hard to spot.

Black holes born with magnetic fields quickly shed them
New computer simulations show one way that black holes might discard their magnetic fields.

With Steven Weinberg’s death, physics loses a titan
The Nobel laureate advanced the theory of particles and forces, and wrote insightfully for a wider public.

These weird, thin ice crystals are springy and bendy
Specially grown fibers of frozen water bend into curves and spring back when released.

Scientists spotted an electron-capture supernova for the first time
A flare that appeared in the sky in 2018 was an electron-capture supernova, a blast that can occur in stars too small to go off the usual way.

An atomic clock that could revolutionize space travel just passed its first test
The most precise clock ever sent to space successfully operated in Earth’s orbit for over a year.

This moon-sized white dwarf is the smallest ever found
A newfound white dwarf is the smallest and perhaps the most massive known, and spins around once every seven minutes.

Gravitational waves reveal the first known mergers of a black hole and neutron star
For the first time, LIGO and Virgo have detected long-anticipated gravitational waves from a black hole merging with a neutron star.
