Male corals outnumber females in Baja California’s acidified waters. Michael Hellberg’s new NSF grant uses fieldwork, genomics, and AI to reveal why—and how these sex-specific strategies help corals endure a changing ocean. https://www.lsu.edu/science/news/2025/10/hellberg-baja-corals-nsf.php

If you're curious about #LSU's new scanning transmission electron microscope, the most advanced microscope in Louisiana, you're not alone. It's a BIG deal (almost 13' tall).

What happens when LSU researchers in biology and chemistry tackle the problem of antibiotic resistance? They find innovative new ways, and iron homeostasis pathways, that may serve as the foundation of a future class of drugs! Learn more with our first ever Research Comic! 🦠
Mike sits in his doctor's office during a follow-up visit for a lingering bacterial infection that is threatening his health. As he sits on the examination table, his doctor discusses options with him. "This is a tricky infection. There's one more antibiotic we can try." "Why aren't there more drug options?" Mike asks, confused. "Bacteria adapt quickly to existing drugs, but LSU researchers are now exploring ways to kill bacteria by starving them of iron." Mike's doctor explains bacteria's need for iron as a Goldilocks and the Three Bears situation... too much iron is poisonous ("Ack, too much!" the bacteria says...), but too little can also harm the bacteria... “LSU researchers are studying how bacteria monitor and regulate their iron levels…" Mike's doctor explains. While Mike's immune cells are busy protecting the iron in his body from bacterial thieves, the microbes that are causing his infection have a back-up plan: iron in storage. They can sense when their iron levels are low thanks to a sensitive iron-sensing pathway. The pathway involves a protein called ferredoxin that is activated by a signaling iron-sulfur cluster. “I’m running low! This man’s immune cells are hogging all the iron!” the microbe says. "Go get your own!" the immune cell yells back. An active ferredoxin helps to release iron particles normally stored in a large round container protein called bacterioferritin. A drug that interferes with this release of stored iron could kill the bad bacteria in Mike's body, helping his immune cells win their fight. "LSU researchers are also studying how a new drug that locks iron in storage can kill biofilm bacteria," the doctor says. Mike imagines a sick bacterium with bloodshot eyes, sighing, "UGHHH! I don't feel good..." A new type of antibiotic could prevent ferredoxin and bacterioferritin from interacting, trapping iron inside its storage container and tricking bacteria into thinking they have no iron available. Research saves lives!

“We evolved from fishes. We do what we do, including breathing through lungs, having nostrils that fill those lungs, having arms and legs, and big brains, all of which came from our aquatic ancestors. So did kidneys, lungs, and being able to pee!”— @prosanta.bsky.social

Did you know there is a leaf cutter ant native to the southeastern US? Atta texana, the Texas leaf cutter ant, is found from Louisiana to Mexico, and can form massive colonies of millions of ants! Like tropical leaf cutter ants, they use plant material to “farm” a fungus that they eat 🍄‍🟫 🍃 🐜
