Research suggests fresh grapes are a superfood

California Table Grape Commission
Peer-Reviewed Publication

A new article appearing in the current issue of the peer-reviewed Journal of Agriculture and Food Chemistry explores the concept of “superfoods” and makes a case that fresh grapes have earned what should be a prominent position in the superfood family.[1] The author, leading resveratrol and cancer researcher John M. Pezzuto, Ph.D., D.Sc., Dean of the College of Pharmacy and Health Sciences at Western New England University, brings forth an array of evidence to support his perspective on this issue.

Integrating sulfur into crystalline nanostructures fuels catalytic activity

Northwestern University
Peer-Reviewed Publication

Researchers from Northwestern University have developed a novel approach to integrate metal-sulfur active sites into metal-organic frameworks, or MOFs. Sulfur-containing MOFs significantly outperformed their non-sulfur counterparts in hydrogenation catalysis, paving the way for more accessible methods to study the active sites they create.

Astronomers discover star-shredding black holes hiding in dusty galaxies

Massachusetts Institute of Technology
Peer-Reviewed Publication

For the first time, the James Webb Space Telescope has observed several tidal disruption events — when a black hole draws in a nearby star and tears it to shreds. Surprisingly, these are not active black holes, but rather dormant ones that briefly “wake up” to feast on a passing star.
