Scientists have created the first-ever atomic movies showing how atoms rearrange locally within a quantum material as it transitions from an insulator to a metal. With the help of these movies, the researchers discovered a new material phase that settles a years-long scientific debate and could facilitate the design of new transitioning materials with commercial applications.

The key to developing quantum electronics may have a few kinks. According to researchers, that's not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors and lasers. The researchers fabricated a switch to turn on and off the presence of kink states, which are electrical conduction pathways at the edge of semiconducting materials.

An international team of researchers has found that nitrogen emissions from fertilizers and fossil fuels have a net cooling effect on the climate. But they warn increasing atmospheric nitrogen has further damaging effects on the environment, calling for an urgent reduction in greenhouse gas emissions to halt global warming.

Researchers are investigating ways to better plan for climate-resilient energy systems in the Global South. Focusing on the case study of Accra, the capital of Ghana, the multidisciplinary team expanded conventional energy system modeling approaches by incorporating a range of socio-techno-economic challenges, climate change impacts, and resilience metrics into their models. Their approaches are applicable worldwide to support widespread sustainable and resilient energy system transitions.

Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating the so called non-conservative interactions.

Newly announced research examining greenhouse gas emissions from the drying lake bed of Great Salt Lake, Utah, calculates that 4.1 million tons of carbon dioxide and other greenhouse gases were released in 2020. This research suggests that drying lake beds are an overlooked but potentially significant source of greenhouse gases, which may further increase due to climate change.
