Earwax: A New Frontier of Human Odor Information

Monell Chemical Senses Center

Scientists from the Monell Center have used analytical organic chemistry to identify the presence of odor-producing chemical compounds in human earwax. Further, the amounts of these compounds differ between individuals of East Asian origin and Caucasians. The findings suggest that human earwax could be an overlooked source of personal information.

The Play-by-Play of Energy Conversion: Catching Catalysts in Action

Brookhaven National Laboratory

Before catalysis unfolds in a laboratory, scientists painstakingly assemble the materials and spark a reaction. But many experimental techniques only capture the static details before and after the reaction. Now, researchers at the U.S. Department of Energy’s Brookhaven National Laboratory have demonstrated an unprecedented ability to peer into the dynamic, real-time reactions blazing along at scales spanning just billionths of a meter, producing a sort of play-by-play view of the chemistry in action.

Designing Genes Through Diagnosis

American Association for Clinical Chemistry (AACC)

A new Q&A in the “Advancing Women’s Health” issue of Clinical Chemistry, the journal of AACC, explores the ethics of preimplantation genetic diagnosis, a form of genetic testing that has already made it possible for parents to conceive a child who is a donor match for a sick relative, who shares their minor disability (such as deafness), or to select gender.
