Messier 85 has a peculiar globular cluster system, study finds

Astronomers have conducted a study of stellar population and kinematics of globular clusters (GCs) in the galaxy Messier 85, and found that this galaxy hosts a peculiar globular cluster system. The finding is reported in a paper published October 6 on the arXiv pre-print repository.

Researchers create a new 'green' engine for lorries

Researchers from the Polytechnic University of Valencia (UPV) have designed a new engine to decrease the environmental impact of the most common type of lorries that travel on European roads—those that weigh between 18 and 25 tons. From their laboratories at the CMT-Thermal Engines of the UPV, they propose a new configuration that unites all the benefits of hybrid and dual-fuel combustion engines.

High-confidence approach for artificial intelligence-based models

They call it artificial intelligence—not because the intelligence is somehow fake. It's real intelligence, but it's still made by humans. That means AI—a power tool that can add speed, efficiency, insight and accuracy to a researcher's work—has many limitations.
