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.
Researchers have successfully tested a new immunotherapy approach that targets brain plaque and tau protein aggregates linked to Alzheimer's disease. The treatment, developed using a combination of vaccines, shows promise for preventing dementia in humans within two years.
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.
The study reveals that different classes of neurons control positive and negative motivation, sending opposing signals along a shared brain circuit. This balance determines whether an individual seeks pleasurable experiences or avoids negative ones.
Researchers found that treatment with intranasal mupirocin and chlorhexidine wipes significantly reduced parentally acquired Staphylococcus aureus infections in NICU babies. The study suggests a simple strategy to reduce the spread of deadly bacteria in hospitals.
Scientists at Institut Pasteur and CNRS identified molecules capable of inhibiting DNA methylation, killing even the most resistant Plasmodium falciparum parasites. The results showed significant activity comparable to chloroquine, with some inhibitors killing parasites in just 6 hours.
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.
A new study reveals that human noroviruses infect small intestine cells by piggybacking on endocytosis, a normal process used to acquire materials from the environment. Bile acids and ceramide play a crucial role in this process.
Researchers at Mayo Clinic tested a new injection method for delivering gene therapy vectors directly into the kidney, outperforming traditional intravenous injections. The study found that direct injections were superior to intravenous injections and had fewer off-target effects.
