Controlling exciton flow in moiré superlattices: New method leverages correlated electrons

Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling the transport of energy in electronic devices. These pairs of charge carriers also emerge in transition metal dichalcogenides, thin semiconducting materials comprised of a tran…

Modifying chirality with electricity: Voltage-driven method enables reversible, tunable states

A way to electrically modify the chirality of organic–inorganic hybrid materials, in which chiral molecules adsorb onto inorganic surfaces, has been demonstrated by researchers at Science Tokyo. By using an electric double-layer transistor with a chiral electrolyte, specific chirality was imposed on…

First beta-delayed neutron emission observed in rare fluorine-25 isotope

A research team at the Facility for Rare Isotope Beams (FRIB) is the first ever to observe a beta-delayed neutron emission from fluorine-25, a rare, unstable nuclide. Using the FRIB Decay Station Initiator (FDSi), the team found contradictions in prior experimental findings. The results led to a new…

Scientists who use AI tools are publishing more papers than ever before

Science is entering a massive publishing boom, in large part due to artificial intelligence. New research published in the journal Science has revealed that scientists who use large language models (LLMs) like ChatGPT are producing significantly more papers across many fields. The technology is also…

Grid-Scale Bubble Batteries Will Soon Be Everywhere

This giant bubble on the island of Sardinia holds 2,000 tonnes of carbon dioxide. But the gas wasn’t captured from factory emissions, nor was it pulled from the air. It came from a gas supplier, and it lives permanently inside the dome’s system to serve an eco-friendly purpose: to store large amount…

We May Never Know if AI Is Conscious, Says Cambridge Philosopher

As claims about conscious AI grow louder, a Cambridge philosopher argues that we lack the evidence to know whether machines can truly be conscious, let alone morally significant. A philosopher at the University of Cambridge says we currently have too little reliable evidence about what consciousness…

The Surprising Things Scientists Are Learning About Diabetes Drugs and Cancer

Diabetes drugs may be doing more than managing blood sugar, they could also shape cancer biology in unexpected ways. New research is taking a closer look at how diabetes drugs may relate to cancer, with an emphasis on effects that go beyond lowering blood sugar or supporting weight control. Although…

Quantum entanglement could connect drones for disaster relief, bypassing traditional networks

Any time you use a device to communicate information—an email, a text message, any data transfer—the information in that transmission crosses the open internet, where it could be intercepted. Such communications are also reliant on internet connectivity, often including wireless signal on either or …
