Better but not stellar: Pollsters faced familiar complaints, difficulties in assessing Trump-Harris race
An oracle erred badly. The most impressive results were turned in by a little-known company in Brazil. A nagging problem reemerged, and some media critics turned profane in their assessments......»»
Simulations reveal black holes inherit magnetic fields from parent stars
Black holes are one of the most enigmatic stellar objects. While best known for swallowing up their surroundings into a gravity pit from which nothing can escape, they can also shoot off powerful jets of charged particles, leading to explosive bursts.....»»
Astronomers discover a unique quasi-stellar object–dusty star-forming galaxy system
Astronomers from the Steward Observatory in Arizona and elsewhere report the discovery of a structure consisting of a quasi-stellar object (QSO) and a dusty star-forming galaxy (DSFG), linked by a bridge of ionized carbon. The finding of this unique.....»»
New on-chip device uses exotic light rays in 2D material to detect molecules
Researchers have developed a highly sensitive detector for identifying molecules via their infrared vibrational "fingerprint." This innovative detector converts incident infrared light into ultra-confined "nanolight" in the form of phonon polaritons.....»»

A new way to detect daisy worlds
The daisy world model describes a hypothetical planet that self-regulates, maintaining a delicate balance involving its biogeochemical cycles, climate, and feedback loops that keep it habitable. It's associated with the Gaia Hypothesis developed by J.....»»
NASA satellites reveal abrupt drop in global freshwater levels
An international team of scientists using observations from NASA-German satellites found evidence that Earth's total amount of freshwater dropped abruptly starting in May 2014 and has remained low ever since. Reporting in Surveys in Geophysics, the r.....»»
Ytterbium thin-disk lasers pave the way for sensitive detection of atmospheric pollutants
Alongside carbon dioxide, methane is a key driver of global warming. To detect and monitor the climate pollutants in the atmosphere precisely, scientists at the Max Planck Institute for the Science of Light (MPL) have developed an advanced laser tech.....»»
