Nitrenes are the ghosts of synthetic chemistry, formed in an instant and gone just as quickly, rearranging into something entirely different. These highly reactive intermediates are widely used in synthesis, yet remain notoriously ...
Antibiotic resistance is becoming an accelerating crisis because of the overuse and misuse of antibiotics over many years. The problem is exacerbated when antibiotics wipe out susceptible bacteria but leave resistant bacteria ...
The main reason for sealing wine bottles with a cork is to protect the liquid from oxygen. However, it is not an impermeable barrier, and a small amount of air leaks in, which is not always entirely bad news. The gas helps ...
Cells sitting side by side in the same tissues are not identical. Each cell carries its own subtly different chemical signature—a hidden individuality that can reveal how diseases take root and spread. Now, researchers from ...

Quantum states can be precisely controlled with the help of tiny carbon rings measuring only a few nanometers in size. This is made possible by a class of rarely used electromagnetic dipoles called toroidal moments. Using ...

Water is the most abundant liquid on Earth's surface, and it is highly anomalous compared with other liquids because it expands upon freezing. The anomalies in water have been linked to how its microscopic structure changes ...

Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply ...
