A third of California methane traced to a few super-emitters

NASA scientists are helping California create a detailed, statewide inventory of methane point sources—highly concentrated methane releases from single sources—using a specialized airborne sensor. The new data, published ...

Green energy nudges come with a hidden cost

All across the United States, many households receive energy bills comparing their use to that of similar neighbors to remind them to use less energy. At most companies, employees are automatically enrolled in 401(k) plans ...

Artificial photosynthesis gets big boost from new catalyst

A new catalyst created by U of T Engineering researchers brings them one step closer to artificial photosynthesis—a system that, just like plants, would use renewable energy to convert carbon dioxide (CO2) into stored chemical ...

Radio telescopes unravel mystery of nova gamma rays

Highly-detailed radio-telescope images have pinpointed the locations where a stellar explosion called a nova emitted gamma rays, the most energetic form of electromagnetic waves. The discovery revealed a probable mechanism ...

Most distant blazar is a high-energy astrophysics puzzle

(Phys.org) —Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of the blazar known as PKS 1424+240 show that it is the most distant known source of very high-energy ...

Single photon from a quantum emitter? It's a matter of timing...

(Phys.org) —Many systems envisioned for practical quantum information processing require the use of single, indistinguishable photons as carriers of information and logic operators. So researchers in the field need to be ...
