Weizmann Institute scientists introduce a powerful tool to explore quantum phenomena — the cryogenic Quantum Twisting Microscope (QTM). Using this pioneering instrument, researchers have observed — for the first time — the interactions between electrons and an exotic atomic vibration in twisted sheets of graphene, called a "phason." These findings shed new light on the mysterious superconductivity and “strange metallicity” that emerge when graphene sheets are rotated to the “magic angle.”

A study by Dartmouth researchers lays out a scientific framework for holding individual fossil fuel companies liable for the costs of climate change by tracing specific damages back to their emissions. The researchers use the tool to provide the first causal estimate of economic losses due to extreme heat driven by emissions. They report that carbon dioxide and methane output from just 111 companies cost the world economy $28 trillion from 1991 to 2020, with the five top-emitting firms linked to $9 trillion of those losses.

MIT researchers developed a machine-learning model that can predict the structures of transition states of chemical reactions in less than a second, with high accuracy. Their model could make it easier for chemists to design reactions that could generate a variety of useful compounds, such as pharmaceuticals or fuels.

Scientists have achieved a major milestone in the quest to understand high-temperature superconductivity in hydrogen-rich materials. Using an electron tunneling spectroscopy under high pressure, the international research team led by the Max Planck Institute for Chemistry has measured the superconducting gap of H₃S – the material that set the high-pressure superconductivity record in 2015 and serves as the parent compound for subsequent high-temperature superconducting hydrides. The findings, published this week in Nature, provide the first direct microscopic evidence of superconductivity in hydrogen-rich materials and an important step toward its scientific understanding.
