Rare Millisecond Pulsar Challenges Traditional Theoretical Models

A team of Chinese researchers has reported the discovery of a new millisecond pulsar, which exhibits an exceptionally high spin-down rate, two orders of magnitude higher than that of other known millisecond pulsars, according to a recent article in Nature Astronomy.

Key Gene Improves Rice Resistance to Disease

Chinese scientists have identified a key gene, which they named Xa48, in an indica rice variety called "Shuangkezao." It helps rice fight off bacterial blight, and the study shows how this defense mechanism can be rebuilt from the ground up. The study was published in Nature.

Next-generation Atomic Clock Tested at Sea

Researchers in Australia have successfully tested a new type of portable atomic clock at sea. The device, trialed aboard a Royal Australian Navy vessel in July 2024, uses laser-cooled atoms of the element ytterbium to keep time with extreme precision. The study was published in Optica.

Archaeological Findings Offer New Insights into Early Humans

The Ethiopian government announced on April 14 the discovery of ancient Homo sapiens fossils and stone tools dating back about 100,000 years, a discovery it said provides "important new insights" into human evolution and early human lifestyles. They were uncovered at a site in the Awash Valley of Ethiopia's Afar Depression, about 300 km northeast of capital Addis Ababa.
