USTC unveils origin of current sheets in turbulent plasmas

Researchers from USTC discovered that current sheets in magnetosheath originate from fast magnetosonic waves excited by ion resonance instability, leading to magnetic reconnection and energy dissipation. The study provides insights into the formation mechanism of coherent current sheet structures in turbulent plasma.

Novel sex-determination mechanism revealed in mammals

Researchers at Hokkaido University discovered a novel sex-determination mechanism in the Amami spiny rat, a species lacking the Y chromosome and Sry gene. The mechanism involves the upregulation of Sox9 gene on chromosome 3, induced by a new regulatory element similar to Enh14.

Saving the Mekong delta from drowning

The Mekong delta, Southeast Asia's most productive agricultural region and home to 17 million people, is at risk of disappearing by the end of the century due to subsidence. Sediment loss from upstream dams and poor water management exacerbates the issue, threatening food security and livelihoods.
