Low-cost sensor for cystic fibrosis diagnosis based on citrate

Penn State biomaterials scientists have developed a new, inexpensive method for detecting salt concentrations in sweat or other bodily fluids. The fluorescent sensor, derived from citric acid molecules, is highly sensitive ...

Invisible X-rays turn blue

A new reaction system can detect X-rays at the highest sensitivity ever recorded by using organic molecules. The system, developed by researchers at Nara Institute of Science and Technology (NAIST), Ikoma, Japan; and Centre ...

Compressive shearing may start life on other planets

Massive compressive shearing forces generated by the tidal pull of Jupiter-like planets on their rocky ice-covered moons may form a natural reactor that drives simple amino acids to polymerize into larger compounds. These ...
