Tropical bounty: How forests can turn into chemical factories

Washington University in St. Louis
Peer-Reviewed Publication

A new study led by researchers at Washington University in St. Louis and the Missouri Botanical Garden has uncovered a surprising layer of diversity in tropical forests. Not only are the forests populated by a dizzying number of tree species, but each of those species takes a different approach to chemistry, increasing the array of natural compounds that provide important functions for the plants — and potentially for humans.

UH researcher unveils new model to evaluate impact of extreme events and natural hazards

University of Houston
Peer-Reviewed Publication

A University of Houston professor of engineering has created a sophisticated computer model that tracks how water moves in estuaries – which is critical for evaluating climate variability and sea level fluctuation impacts for coastal communities.

Fighting honey fraud with AI technology

McGill University

McGill University researchers have developed an AI-powered method to verify the origin of honey, ensuring that what’s on the label matches what’s in the jar. The breakthrough offers a potential solution to a long-standing problem.

“Honey is one of the most fraud-prone commodities in global trade. It often involves mislabelling where it was produced or the types of flowers that bees collected nectar from,” said lead author Stéphane Bayen, Associate Professor and Chair of McGill’s Department of Food Science and Agricultural Chemistry.

Breaking limits: Full-aperture grating compressor paves the way for single-channel 100-petawatt ultrafast lasers

Ultrafast Science

Recently, a research team from Shanghai Institute of Optics and Fine Mechanics (SIOM), Chinese Academy of Sciences, published a groundbreaking study in Ultrafast Science, demonstrating a novel Full-Aperture Grating Compressor (FAGC). This innovation overcomes critical limitations in traditional 4-grating compressors and provides key technical support for achieving single-channel 100-petawatt (PW) ultra-intense ultrafast lasers, a milestone in extreme physics research.

Artful single-atom catalyst for sustainable chemical and pharmaceutical synthesis

National University of Singapore
Peer-Reviewed Publication

National University of Singapore (NUS) chemists have developed an “anchoring-borrowing” strategy, combined with facet engineering, to develop a new class of artful single-atom catalysts (ASACs). These catalysts are formed by anchoring foreign single atoms onto specific facets of reducible support materials, allowing them to bypass the traditional oxidative addition step in cross-coupling reactions, which are widely used in the fine chemical and pharmaceutical industries.
