Researchers propose a new route to electrically control magnetism using molecular ferroelectric altermagnets. By tuning molecular dipole alignments, the team demonstrates that spin polarization can be switched on, off, or reversed without altering magnetic order. Verified through theoretical model and first-principles studies in hybrid perovskites and metal-organic frameworks, this work introduces a flexible, low-power platform for electrically driven spintronics, bridging molecular ferroelectrics and next-generation magnetic memory technologies.

Researchers at Osaka Metropolitan University have verified the decomposition and detoxification capabilities of ultrasonic irradiation on the harmful organic compound, carbon tetrachloride (CCl₄).

Caroline Casey and her team study the seals on Año Nuevo Island off the coast of California, and they have observed male elephant seals engaging in dominance displays year after year. This led them to wonder if the seals remembered their past bouts. To test this, the team would find a male seal returning to the island and play recorded calls from his old rivals. When males heard their most familiar dominant rival from the previous year, they reacted faster than they did to unfamiliar calls.
