Silk microneedles deliver controlled-release drugs painlessly

Bioengineers at Tufts University School of Engineering have developed a new silk-based microneedle system able to deliver precise amounts of drugs over time and without need for refrigeration. The tiny needles can be fabricated under normal temperature and pressure and from water, so they can be loaded with sensitive biochemical compounds and maintain their activity prior to use. They are also biodegradable and biocompatible.

Seven things you may not know about catalysis

Catalysts are one of those things that few people think much about, beyond perhaps in high school chemistry, but they make the world tick. Almost everything in your daily life depends on catalysts: cars, Post-It notes, laundry detergent, beer.

Fastest X-ray images of protein nanocrystals

An international research team headed by DESY scientists from the Center for Free-Electron Laser Science (CFEL) in Hamburg, Germany, has recorded the shortest X-ray exposure of a protein crystal ever achieved. The incredible brief exposure time of 0.000 000 000 000 03 seconds (30 femtoseconds) opens up new possibilities for imaging molecular processes with X-rays.
