Students who ride newer, cleaner-air buses to school have improved academic performance, according to a U-M study that linked school bus funding information with standardized test scores and found improvements in reading/language arts and math scores when the oldest buses were replaced with newer vehicles.

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.

In February 1970, U-M students operating as the Black Action Movement called a strike on classes. They interrupted lectures, banged garbage-can lids in classroom buildings, and hassled fellow students attending class. Their demand to President Robben Fleming: Increase Black enrollment from 3.4 percent to 10 percent.

Purpose and mattering. They’re essential to happiness and healthiness, researchers say. But those feelings can be hard to attain, especially for individuals who may be more prone to feeling purposeless. Professor John Piette, director of the U-M Center for Managing Chronic Disease, discusses V-SPEAK, his latest project with U.S. veterans.
