A razor blade drawn across a soft contact lens creates a notch approximately a third of the way deep, sufficient to refract light and attract attention. Illuminate that same lens with ultraviolet light for an hour at ambient temperature, and the notch repairs itself. The surface nearly returns to seamlessness. No heat, no adhesive, no […]

Chemists have made a remarkable advancement by capturing an image of a highly reactive boron-bound nitrene through in situ crystallography. This marks the inaugural occasion researchers have explored this elusive species, more than 40 years after its initial prediction. Nitrenes are extremely reactive intermediates because their nitrogen atoms contain two unpaired electrons, rendering them useful […]

Many chemical connections might be more accurately portrayed as one-electron connections. This is the conclusion drawn by researchers in Spain, whose computational research uncovered instances wherein, instead of a pair of delocalized electrons, the bonding is influenced by a solitary ‘active’ electron, while a second ‘spectator’ electron stays predominantly localized on one component. Investigating straightforward […]

Herpes simplex virus 2 (HSV-2) results in genital herpes, impacting over 500 million individuals globally. The virus penetrates through the vaginal lining and rapidly targets the nervous system, residing in nerve clusters adjacent to the spine, which renders it resistant to elimination by medications. The development of a vaccine has proven difficult, partly because conventional […]
