Large language model predicts how to make inorganic compounds
The team trained the new model using chemical synthesis protocols extracted from 13 878 inorganic compounds, which they sourced from a collection of over four million scientific publications. Courtesy:...
View ArticleLight evaporates water without heating it
Under certain conditions, light can cause water to evaporate directly, without heating it first. The process works by cleaving water clusters from the water-air interface, and researchers at the...
View ArticleUnifying gravity and quantum mechanics without the need for quantum gravity
Jonathan Oppenheim at University College London has developed a new theoretical framework that aims to unify quantum mechanics and classical gravity – without the need for a theory of quantum gravity....

Have you ever wished you could go back in time and change your decisions? If only knowledge from today could travel back in time with us, we could alter our actions to our advantage. For now, such time...
View ArticleSpiralling phonons turn a paramagnetic material into a magnet
When a material’s atomic lattice vibrates, it produces quasiparticles known as phonons, or quantized sound waves. In certain materials, vibrating the lattice in a corkscrew pattern will make these...
View ArticleNew protocol transmits quantum information in complex states of light
Quantum information could be transmitted more efficiently thanks to a new protocol that uses nonlinear optics to transfer high-dimensional, spatially complex states of light. Developed by researchers...
