Researchers have discovered a much larger transverse figure of merit in topological semimetals compared to their longitudinal counterparts. This is attributed to the coexistence of electrons and holes contributing additively and high charge mobility without lattice imperfections.
A new study published in Frontiers in Marine Science found that eDNA (environmental DNA) can identify more species of marine vertebrates than traditional trawl nets. The research team collected water samples and analyzed the DNA to detect the presence of important species such as great white sharks and salmon.

Researchers found that individuals with objective subtle cognitive difficulties accumulated amyloid protein faster than cognitively normal individuals, even before symptoms appeared. This suggests that sensitive neuropsychological measures can detect subtle cognitive changes earlier in the disease process.

NASA's Suomi NPP satellite provided a visible image of Tropical Cyclone Sarai, showing a weaker storm near Tonga. The storm is rapidly weakening and dissipating under adverse atmospheric conditions.
Researchers have made significant progress in generating functional hematopoietic stem cells from human pluripotent stem cells. Key findings include the role of transcription factors HOX and GATA proteins in regulating hematopoiesis, which may lead to breakthroughs in treating blood cancers and other disorders.

Tropical Storm Calvinia has moved south of the island of Mauritius in the Southern Indian Ocean, with a tropical cyclone warning class III still in effect. The storm is expected to turn southeast and strengthen to 65 knots, eventually becoming extra-tropical after January 1.
Researchers in a new study employ RNA sequencing techniques to classify brain cells in crabs, finding that single-method approaches yield inaccurate results. By combining multiple modalities of data, they reveal more accurate cell identities.
