UK researchers have discovered a new use for metal-organic frameworks (MOFs) - as potential lighting devices.
MOFs consist of inorganic nodes connected by organic linker molecules to form three-dimensional molecular cages. So far MOFs have attracted interest as a way to store gases such as hydrogen or carbon dioxide, or as novel catalytic materials.
Now, Anthony Cheetham from the University of Cambridge and colleagues have shown that MOFs can also act as a novel source of white light.
Weak gravitational lensing is a uniquely promising way to learn how much dark matter there is in the Universe and how its distribution has evolved since the distant past. New work by a team led by a cosmologist from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory has made major progress in extending the use of gravitational lensing to the study of much older and smaller structures than was previously possible.

It's big. It's ugly. And it's made from recycled parts, at least for now. It's called the "Frankencamera" — and it might someday change the way you take pictures.
Diamonds, it has long been said, are a girl’s best friend. But a research team including a physicist from the National Institute of Standards and Technology (NIST) has recently found* that the gems might turn out to be a patient’s best friend as well.
Howard Hughes Medical Institute researchers are reporting the first detailed molecular snapshots of a deadly gastrointestinal virus as it is caught in the grasp of an immune system molecule with the capacity to destroy it. The images could help scientists design a more effective vaccine against rotavirus, a lethal infection that kills more than 500,000 children worldwide each year. The discovery is timely.
