Shedd Aquarium and Purdue researchers are studying how 80 fish respond to new habitat restoration initiatives, flooding and sewage overflows, as well as seasonal changes.
how they respond to new habitat restoration initiatives, flooding and sewage overflows, as well as seasonal changes.
Austin Happel, a Shedd Aquarium research biologist, looks over detailed information on his cellphone and a receiver that tracks the tag number, GPS, decibel noise levels and other information, used to track fish in the South Branch of the Chicago River near South Ashland Avenue in Chicago on Sept. 6, 2023. The Shedd, Purdue University and the Illinois-Indiana Sea Grant are looking to understand how habitat restoration initiatives such as artificial floating wetlands, affect aquatic life.
The group is tracking bluegill and largemouth bass to learn more about fish that people like to catch for fun. Austin Happel, Shedd Aquarium research biologist, pulls out a microphone attached to a receiver that was underwater to track fish in the South Branch of the Chicago River near south Ashland Avenue in Chicago on Sept. 6, 2023.
“Unlike a normal project, where we set up, like, three main questions that we want to answer, this is more like: Let’s have fish tell us what habitats are most important to them,” Happel said.

In major breakthrough, researchers close in on potential preeclampsia cureResearchers have achieved a significant breakthrough in identifying the primary cause and potential treatment for preeclampsia, a severe pregnancy complication. Experts pinpointed a toxic protein named cis P-tau in the blood and placenta of individuals with preeclampsia. The study describes cis P-tau as a pivotal circulating instigator of preeclampsia. An antibody developed in 2012 to target only the toxic protein while leaving its healthy counterpart unscathed is currently undergoing clinical trials in human patients suffering from traumatic brain injury and Alzheimer's Disease. The antibody has shown promising results in animal models and human cell cultures in treating the brain conditions. Upon testing this antibody in mice, the researchers found the all symptoms associated with preeclampsia were corrected.

Researchers uncover unconventional charge carriers in a triangular-lattice Mott insulatorMott insulators are a peculiar class of materials with structures that should theoretically conduct electricity, but that are instead insulators. These materials contain strongly correlated electrons, which can generate highly entangled many-body states marked by unconventional excitations.
