Small but mighty: Tiny proteins with big roles in biology (Update)

We all know how hard it is to find something small like a dropped contact lens that blends into the background. It's similarly tough for biologists to find tiny proteins against the complex background of the cell. But, increasingly, ...

Carbon-carbon bond formation using flow chemistry

(Phys.org)—Traditionally, C-C bond forming reactions require the use of a precious metal, such as palladium, to catalyze the reaction. Precious metals are expensive and because pharmaceutical ingredients require a very ...

New test detects drug use from a single fingerprint

Research published today in the journal Analyst has demonstrated a new, noninvasive test that can detect cocaine use through a simple fingerprint. For the first time, this new fingerprint method can determine whether cocaine ...

Analyzing the status of oxide surface photochemical reactivity

As shown by Pacific Northwest National Laboratory's Dr. Michael Henderson and Dr. Igor Lyubinetsky in their invited review article, using scanning probe microscopy techniques, in particular scanning tunneling microscopy or ...

Live pathogens: Rapid detection technique developed

(Phys.org)—Los Alamos researchers have developed a better technique for quick detection of live pathogens in the field. Identification of viable bacteria in a complex environment is scientifically challenging. Current detection ...

Solving mysterious enzyme structure

Scientists at the Max Planck Institute for Chemical Energy Conversion (MPI CEC) have solved a long-standing puzzle in photosynthesis research. With the aid of quantum chemistry they were able to provide unexpected insight ...
