A team at the Texas Center for Superconductivity used a pressure-quenching technique on a mercury-based copper-oxide ceramic to achieve a transition temperature of 151 K at ambient pressure, surpassing a record that had stood since 1993.

The US Department of Energy has opened a $1.9 billion funding round under its SPARK program to accelerate grid modernization by replacing aging transmission wires with advanced conductors, a strategy that can double line capacity at half the cost of building new infrastructure.

A Science Advances study identifies cell-free ice-nucleating proteins in Mortierellaceae soil fungi, acquired from bacteria via horizontal gene transfer, offering a non-toxic alternative to silver iodide for cloud seeding.

A Japanese research team has identified a small molecule called Mic-628 that advances the mammalian circadian clock by activating the Period1 gene through a previously unexploited molecular pathway, cutting simulated jet lag recovery from seven days to four in mice after a single oral dose.

Three major studies reveal invasive species cut insect numbers by 31 percent globally, climate change alone drove a 72 percent decline in a pristine Colorado meadow, and monitoring frameworks cannot yet track whether rescue plans work.
