Molecule snapshot by explosion
Exploding a photo subject in order to take its picture? An international research team at the European XFEL, the world's largest X-ray laser, applied this "extreme" method to take pictures of complex molecules. The scientists used the ultra-bright X-.....»»
Combining extreme-ultraviolet light sources to resolve a quantum mechanical dissociation mechanism in oxygen molecules
For the first time, researchers have succeeded in selectively exciting a molecule using a combination of two extreme-ultraviolet light sources and causing the molecule to dissociate while tracking it over time. This is another step towards specific q.....»»

Astronomers are hoping to detect gravitational waves coming from supernova 1987A
A supernova explosion is a cataclysmic explosion that marks the violent end of a massive star's life. During the event, the star releases immense amounts of energy, often outshining the combined light from all the stars in the host galaxy for a very.....»»
New antifungal molecule kills fungi without toxicity in human cells, mice
A new antifungal molecule, devised by tweaking the structure of prominent antifungal drug Amphotericin B, has the potential to harness the drug's power against fungal infections while doing away with its toxicity, researchers at the University of Ill.....»»
An optical and electrically driven single-molecule Raman switch
The role of molecular junctions in nanoelectronics is most often associated with electronic transport; however, their precise characterization hinders their widespread development. Recently, most research has focused on investigating molecular juncti.....»»
