With 5,000 tiny robots in a mountaintop telescope, researchers can look 11 billion years into the past. Now, using the largest 3D map of our cosmos ever constructed, the Dark Energy Spectroscopic Instrument reveals the most precise measurements to date of how fast the universe has expanded throughout its history.

Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly. While such disks have been imaged, just two planets have been caught in the act of forming so far. Astronomers are now aiming the James Webb Space Telescope at protoplanetary disks to find clues about the ways in which planets form, and how they influence their natal disk.

The first stem cell culture method that produces a full model of the early stages of the human central nervous system has been developed by a team of engineers and biologists at U-M, the Weizmann Institute of Science, and the University of Pennsylvania. The model, which resembles all three sections of the embryonic brain and spinal cord, could shed light on developmental brain diseases.

For the first time, load-bearing structures like bridges and shelters can be made with origami modules — versatile components that can fold compactly and adapt into different shapes. It’s an advance that could enable communities to quickly rebuild facilities and systems damaged or destroyed during natural disasters, or allow for construction in places that were previously considered impractical, including outer space.

When Italy’s Mount Vesuvius erupted in AD 79, it buried the palatial villa of Lucius Calpurnius Piso Caesoninus, Julius Caesar’s father-in-law. These black and brittle papyri may look like charred croissants, but U-M classicist Richard Janko believes they contain lost masterpieces of literature, history, and philosophy.

Michigan explores the academic outer limits, introducing extended and virtual reality to the classroom. Its XR studio opens a new chapter on scalable, personalized, and immersive learning technologies. Oh, the places you’ll go!

The U.S. Army has extended its long-running relationship with the U-M Automotive Research Center, reaching a new five-year agreement of up to $100 million to boost work on autonomous vehicle technologies. As automakers explore self-driving cars, the Army-funded center will figure out how to take the tech off-road.

“Histotripsy” is a technique created by U-M engineers and doctors that harnesses soundwaves to attack cancer. It comes with the promise of few, if any side effects, a quick treatment time and, for patient Carrie Kumpel, the hope that it would completely destroy three spots that had formed on her liver.

A U-M study shows accurate AI models improved diagnostic decisions, but biased models led to serious declines. Researchers and policymakers are taking steps to ensure AI models are safe, secure, and trustworthy — and that their use would lead to improved outcomes.
