Famous oddball quasar isn't X-ray weak after all, astronomers say
For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe ...

Recyclable glue bonds underwater in seconds and holds for years
Most glues need a dry surface to stick properly. Bonding materials underwater is challenging because water forms a thin film on any surface, so instead of an adhesive touching a material directly, it touches a layer of water, ...
Why AI may boost carbon emissions instead of cutting them
AI data centers get a bad rap, not least because of concerns that they drive climate change by consuming massive amounts of electricity. But one potentially larger impact of AI on global carbon emissions may be that it's ...
A surprising pathway that lets the striatum talk directly to the auditory cortex
For decades, neuroscientists have thought about communication between the cerebral cortex and the basal ganglia in a fairly linear way. The cortex sends information into the basal ganglia, where that information is processed ...
Electrochemical method could make seawater a low-cost source of magnesium salts
Magnesium supplements are gaining popularity to treat conditions such as insomnia, migraines and constipation. Most magnesium salts are extracted from rocks by crushing and heating them, which requires a lot of energy. Now, ...
