Researchers at Yale University have developed a new way of exposing the atomic attachments that keep complex molecules in precise alignment. The new method could provide insight into the mechanics of a variety of molecular structures, potentially aiding efforts to manipulate them for drug discovery and other purposes.

“The method appears likely to become a central tool for the characterization of processes that depend on supramolecular associations,” said Mark Johnson, a Yale chemistry professor and the principal investigator of the technique, which is described in a paper published this month in the journal Science. Supramolecular associations are interactions taking place between molecules, rather than within them. (more…)

For his discoveries about the lives and deaths of stars, the exotic physics of black holes and the origin of chemical elements, UA Regents’ Professor David Arnett has been honored with the Henry Norris Russell Lectureship.

What happens when a star dies? How does a black hole form? What makes the chemical elements that form the building blocks of stars, planets and living beings? (more…)

GAINESVILLE, Fla. — Blueberry wine can provide more potentially healthy compounds than white wines and many red wines, according to a new University of Florida study.

Researchers with UF’s Institute of Food and Agricultural Sciences measured antioxidant content in a Florida-produced blueberry wine and compared it to published reports of antioxidant content in white and red wines made from grapes. Antioxidants are compounds that may offer cells protection from damaging molecules called free radicals. (more…)

From Cancer Research to Energy Storage, Berkeley Lab Scientist Takes on Big Challenges

*Rizia Bardhan, a postdoc at the Molecular Foundry, selected to Forbes’ ’30 under 30′ list*

On a typical day, Rizia Bardhan walks through the doors of Lawrence Berkeley National Laboratory’s Molecular Foundry and immerses herself in the tricky business of tweaking optical spectroscopy equipment to study phase transitions in metal hydrides.

It’s fair to say that what she does is difficult to grasp. Why she does it is easy: “I want to help solve big problems. That’s why I’m here,” she says. (more…)
