An international team of researchers led by physicists at Rice University has stumbled upon a theoretical result that could help experimental physicists create a "Weyl-Kondo semimetal," a quantum material with an assorted collection of properties seen in disparate materials like topological insulators, heavy fermion metals and high-temperature superconductors.

For women using in vitro fertilization to have a child, using either fresh or frozen embryos results in similar success rates for most women, according to an international team of researchers.

Researchers in Brazil have created an optical thermometer capable of measuring temperatures from 750 to 80 K. It operates in real time and in well-defined regions with a spatial resolution ranging from a centimeter to a micrometer. It also has practically no effect at all on the temperature of the...

Physicists at the University of Basel in Switzerland have succeeded in cooling a nanoelectronic chip to a temperature lower than 3 mK. The research team used magnetic cooling to cool the electrical connections as well as the chip itself.

Scientists on the Dark Energy Survey publicly released data from the project's first three years during a special session held at the American Astronomical Society meeting in Washington DC. The release includes information on about 400 million astronomical objects, from distant galaxies billions of light-years away to stars in our...

Researchers at the Harvard-MIT Center for Ultracold Atoms and at the Joint Quantum Institute at the University of Maryland have announced complementary advances in quantum studies that constitute a major step towards the realization of large-scale quantum machines.
