A new technique for making exciting metal oxide frameworks

Metal oxide frameworks, or MOFs, are solid materials which can behave like ultra-fine sponges. The cavities in the sponge are of nanosize—about the size of individual molecules. Being made up of such suitably sized cavities ...

Slow electrons to combat cancer

Ion beams are often used today in cancer treatment: this involves electrically charged atoms being fired at the tumour to destroy cancer cells. Although, it's not actually the ions themselves that cause the decisive damage. ...

How to make a better water filter? Turn it inside out

Removing carbon dioxide from power plant exhaust

Reducing carbon dioxide (CO2) emissions from power plants is widely considered an essential component of any climate change mitigation plan. Many research efforts focus on developing and deploying carbon capture and sequestration ...

Image: Hubble snaps a galactic potpourri of particles

Every now and then, the NASA/ESA Hubble Space Telescope glimpses a common object—say, a spiral galaxy—in an interesting or unusual way. A sharply angled perspective, such as the one shown in this Hubble image, can make ...
