Vibrating mirrors of light create analog of a black hole event horizon

Optical cavities are pairs of light-trapping mirrors and underpin the operation of lasers, atomic clocks and many types of precision sensors. If the distance between the mirrors is changed rapidly enough, some theories predict that the waves inside them should bunch together into
Optical cavities are pairs of light-trapping mirrors and underpin the operation of lasers, atomic clocks and many types of precision sensors. If the distance between the mirrors is changed rapidly enough, some theories predict that the waves inside them should bunch together into short, intense pulses. So far, however, this prediction has never been tested directly.

Software squeezes more data out of Webb Telescope for imaging exoplanets
With a huge and still-growing catalog of exoplanets, researchers are eager to take the next steps: trying to infer what conditions are like on them, either by imaging them directly or by capturing the light that has passed through their atmosphere. Both are substantial challenges

The worse climate change gets, the harder it becomes to stop it
This year may be seen as a turning point in the climate crisis. The U.N. has accepted that global warming is going to exceed 1.5°C, while climate scientists have concluded that the rate of warming has effectively doubled over the past decade.

SynFit guides enzyme engineering by balancing several useful traits at once
Enzymes are biology's tiny chemists. They help build, break and rearrange molecules quickly and precisely. In the lab, scientists have long put enzymes to work making useful chemicals. But nature's enzymes cannot do every reaction a researcher might want. Sometimes scientists nee
