Sarah Green (Chem) has been in Nairobi, Kenya for the launch of the Sixth Global Environmental Outlook (GEO-6) at the United Nations Environmental Assembly (UNEA).
Light-absorbing brown carbon aerosols, emitted by wildfires, remain longer in the atmosphere than expected, which could have implications for climate predictions. Graduate student, Simeon Schum, and researchers Lynn Mazzoleni and Claudio Mazzoleni discuss research on lingering effects of aerosols in Michigan Tech News
One of the most basic characteristics used to describe a stream is how much water it carries—the flow, or more accurately, discharge—which is measured in units of volume per time (typically cubic feet or cubic meters per second). Understanding how river discharge changes with time tells us important information about the stream, including how quickly something that is added to the river will be diluted and moved downstream. A river’s discharge rate also tells us how prone the river is to disturbances and what conditions the organisms that live there experience.
Understanding the river flow is also key for human communities. It allows planning for how quickly we can expect lakes and reservoirs to fill and how much water can be withdrawn for irrigation or drinking.
River flow also helps communities prepare for potential natural disasters, such as understanding how likely a river is to overflow its banks to cause a flood, and how to build culverts and bridges to withstand a flood like the one that Houghton experienced in June.

There is something very noble about Xiaohu Xia’s research. He wants to use palladium, platinum, ruthenium and other corrosion-resistant metals to refine tests to detect biomarkers for cancer and infectious diseases. To do so, he plans to use nanostructures made of these noble metals that mimic natural enzymes and has earned a CAREER Award from the National Science Foundation (NSF) to focus on this research.
The grant covers five years, totaling $457,783, and enables Xia to dig deep into the structure-property relationships of the bimetallic peroxidase mimics at the atomic level. Even small changes in nanostructures can produce big results, demonstrated by his lab with improvements in the catalytic efficiencies of iridium-coated palladium and ruthenium nanostructures.

Tarun Dam led a new study, published this week in Biochemistry, examining the biomechanics of galectin-3’s interaction with glycosaminoglycans (GAG) and proteoglycans. His team includes graduate students Melanie Talaga, Ni Fan, Ashli Fueri, Robert Brown and Research Assistant Professor Purnima Bandyopadhyay.
At the Laboratory of Mechanistic Glycobiology, Dam and his students study the sugar, including glucose and other structural, complex sugars, that fuel our bodies. GAGs assist in controlling growth factor proteins, which go unchecked as cancerous tumors grow.
Even though the findings of the study were unexpected, it opens up new possibilities for understanding glycobiology and biomechanics. “Seeing galectin-3 interact with GAGs and proteoglycans is like finding a rose in the petunias—it’s very unexpected,” Dam says. “It’s fair to say that this requires revisiting the reported biological functions of GAGs, proteoglycans and galectin-3.”
Next, Dam and his team look into additional research, “Now we have to reconsider the whole drama, retracing the steps and actions of that character… we are using cell lines and animal models to study this interaction in a cellular context.”
