SIU Carbondale

The International Festival was a reminder of what makes SIU special — culture, community, and connection.⁣
⁣
From the Parade of Flags to the International Food Fair (and everything in between), thank you to the students, performers, organizations, and volunteers who made this week happen.

When every second matters, hesitation can be the biggest risk.

At SIU, our public health students are using mixed reality through ReviveXR to practice real overdose response scenarios before they face them in the real world.

As childhood myopia surges, SIU team finds cleaner, cheaper way to make a key drug If it seems like more children are wearing glasses, you’re not imagining it. By 2050, scientists project about 50% of tthis he world’s population will be nearsighted. As families and clinicians look f...

Childhood myopia is surging and treatment isn’t cheap. SIU researchers set out to change that.

They turned caffeine from tea & coffee waste into 7-MX, a drug that slows nearsightedness. Cleaner, cheaper, sustainable. Drops from $700 a gram to under 35 cents.

Yesterday’s waste. Tomorrow’s solution.

SIU grad’s research illuminates pollution threats to endangered Calif. fish The Sacramento Deep Water Ship Channel was still and quiet as the boat cut through the morning fog. For Cristina La, then a graduate student at Southern Illinois University Carbondale, this was the mo...

What happens to a tiny fish when the water turns toxic?

SIU grad Cristina La studied pollution in the delta smelt’s last habitat with @ucdavis.bsky.social & CA Fish & Wildlife. Her findings, published in Environmental Pollution, revealed contaminants in every sample, a warning for the ecosystem.

SIU research finds birds in light polluted areas stay up late Birds that are active during the day sing later into the night in places with significant light pollution, according to research by a Southern Illinois University Carbondale professor and his colleagu...

New study: Birds in light-polluted areas sing nearly an hour later at night. SIU’s Brent Pease and OSU’s Neil Gilbert used AI and 180M+ bird calls to link light sensitivity to behavioral change. Published today in @science.org.

New research reveals air traffic controllers are facing sky-high levels of anxiety and depression, and they’re afraid to speak up.
Led by veterans of the tower and cockpit, this study challenges a system that treats mental health like a liability instead of a priority.

Twelve-panel image showing a time-lapse of a single yeast cell falling between grid lines on a hemacytometer slide, with each frame taken every 6 seconds. The slide’s grid lines are 1/10 mm apart. The cell is tracked from top left to bottom right, illustrating its downward motion through a fluid.

Text excerpt explaining Stokes’ Law and its application to calculating the force on a sphere falling through a viscous fluid.

In 1953, SIU Carbondale biologists, funded by Anheuser-Busch, used a microscope, sugar water, and physics to weigh a single yeast cell. No fancy gear, just brains & gravity.

They tracked 67 cells falling in fluid, used Stokes’ Law, and got 7.9×10⁻¹¹ grams, on average.
