Performing chemistry in floating droplets

Could chemists be ready to ditch the venerable test tube, the very symbol of chemistry in the minds of many people? Maybe not quite yet, but Caltech's Jack Beauchamp is working on it.

Sophisticated molecular machines in action

Almost all living organisms from bacteria to humans have gate-like protein complexes in their cell membranes that get rid of unwanted or life-threatening molecules. This is not always advantageous, since in the case of bacteria ...

Preparing protocols for making deuterated biomolecules

Neutron techniques are good for studying light atoms like hydrogen—great for biological molecules that contain large numbers of them. Neutrons are particularly sensitive to isotopic substitution of hydrogen (1H) with deuterium ...

Fungus produces highly effective surfactant

Mortierella alpina lives in the soil and likes to keep cool. This fungus, which belongs to the zygomycetes, grows best at temperatures of 10 to 15 degrees C and occurs mainly in alpine or arctic habitats. In biotechnology, ...

Getting the oil out of befouled water

Oil and water are famously reluctant to mix fully together. But separating them completely—for example, when cleaning up an oil spill or purifying water contaminated through fracking—is a devilishly hard and inefficient ...

New electron microscopy technique limits membrane destruction

Membrane proteins play an important role in many biological processes. Studies suggest they're targeted by more than 50% of all modern medicinal drugs. Unfortunately for researchers, determining their structures has been ...
