Researchers used the European XFEL to create X-ray flashes that were not only extremely short but also reached record intensity for this type of pulse. The researchers focused the X-rays to an area roughly 100,000 times smaller than the cross section of a typical human hair. This

Researchers used the European XFEL to create X-ray flashes that were not only extremely short but also reached record intensity for this type of pulse. The researchers focused the X-rays to an area roughly 100,000 times smaller than the cross section of a typical human hair. This concentrated the X-ray light into a tiny but extremely powerful spot.

The method could enable detailed studies of how electrons behave in atoms and molecules and, in the long term, could even allow researchers to control electrons during chemical reactions. The team has now published the results of the experiment, carried out in April 2026, in the journal Optica.

Glowing liquids could help protect products from counterfeiters using distinctive ultraviolet light signatures

Researchers at Nottingham Trent University have developed room-temperature liquids containing chemical elements that produce distinctive patterns of light. They say the materials could provide a flexible new approach to optical tagging and anti-counterfeiting, while being compati
