In a recent Nature study, scientists have demonstrated an electrically driven perovskite laser using a dual-cavity design, addressing a challenge that has persisted in the field for over a decade.

The dual-cavity laser device developed by a team from Zhejiang University shows a lasing threshold an order of magnitude lower than state-of-the-art electrically driven organic lasers and offers superior operational stability with rapid modulation capabilities.

Phys.org spoke with the research team about their work.

If you’re interested in human performance, what you want is something that’s reliable and repeatable, and thus you want neurobiology because neurobiology gives you mechanism.

For around half a century, scientists have been puzzled by the odd spectral lines produced by solar flares. Now we may have some answers. Anew study looking at solar flares may have solved a 50-year-old mystery about our host star, finding that solar flares may be far hotter than we realized.

Cisco ASA zero-days CVE-2025–20333 and 20362 exploited; CISA issues ED 25–03 for urgent patching.

We’re introducing, a new evaluation that measures model performance on economically valuable, real-world tasks across 44 occupations.

Measuring the object’s non-gravitational acceleration, the team believes they found something “anomalous”
