Electrically Spun Fabric Offers Dual Defense Against Pregnancy, HIV

The only way to protect against HIV and unintended pregnancy today is the condom. It’s an effective technology, but not appropriate or popular in all situations.

A University of Washington team has developed a versatile platform to simultaneously offer contraception and prevent HIV. Electrically spun cloth with nanometer-sized fibers can dissolve to release drugs, providing a platform for cheap, discrete and reversible protection. (more…)

First Atomic-Scale Real-Time Movies of Platinum Nanocrystal Growth in Liquids

Berkeley Scientists Create Graphene Liquid Cells for Electron Microscopy Studies of Nanocrystal Formation

They won’t be coming soon to a multiplex near you, but movies showing the growth of platinum nanocrystals at the atomic-scale in real-time have blockbuster potential. A team of scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley has developed a technique for encapsulating liquids of nanocrystals between layers of graphene so that chemical reactions in the liquids can be imaged with an electron microscope. With this technique, movies can be made that provide unprecedented direct observations of physical, chemical and biological phenomena that take place in liquids on the nanometer scale. (more…)

Design Eye For The Science Guy: Drop-in Clinic Helps Scientists Communicate Data

Some of the figures scientists create are stunning. Others are not – mismatched fonts, poorly aligned tables, clashing colors.  Many fall somewhere in between. A deluge of data presents a challenge to amateur designers, often resulting in a cluttered presentation that can crowd out the figure’s main message. (more…)

Diamonds, Silver and the Quest for Single Photons

*Tiny crystal towers enlighten understanding of photon emission, could inspire diamond microchips for quantum computing*

Building on earlier work, scientists and engineers recently developed a manufacturing process that allows them to craft an assortment of miniature, silver-plated-diamond posts that enable greater control of light producing photons at the atomic scale. The research could prove important for future generations of quantum computers.

Prior research demonstrated how nanowires carved in impurity-laden diamond crystal could efficiently emit individual photons, an important discovery for using light to rapidly read and write quantum-based data. (more…)
