A solution to fracture for durable solar cells

Micro cracks in solar cells are a frequent challenge for manufacturers of solar photovoltaic modules. EU-funded researchers introduced an innovative pre-stressing technique to retard the growth of cracks and make durable ...

ATLAS observes direct evidence of light-by-light scattering

Physicists from the ATLAS experiment at CERN have found the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons – particles of light – interact and change direction. ...

Discovery shows dinosaurs may have been the original lovebirds
