Walking Molecule Now Carries Packages

Chemists from the University of California at Riverside designed two years ago a molecule which could move straight on a flat surface — a nano-walker if you wish. Now, they've found a way to force this walking molecule to carry packages. The nano-worker can now carry two CO2 molecules. And like yourself when you carry two heavy bags, this nano-worker is slower when it carries other molecules. The researchers think their discovery will lead to reliable ways of carrying molecules, an equivalent of the conveyor belts in today's factories.

Natural antibiotics yield secrets to atom-level imaging technique

Frog skin and human lungs hold secrets to developing new antibiotics, and a technique called solid-state NMR spectroscopy is a key to unlocking those secrets. AMPs are the immune system's early line of defense, battling microbes at the first places they try to penetrate, copiously produced in injured or infected frog skin in response to invading pathogens. They can attack viruses, fungi and even cancer cells
