In an experiment on how turbulent boundary layers respond to acceleration in the flow around them, aerospace engineers at the University of Illinois Urbana-Champaign observed an unexpected internal boundary layer.
"The internal boundary layer fundamentally changed the behavior of the flow from what would have been expected without it," she said. According to Saxton-Fox, the basic setup of the wind tunnel experiment has been done; what's new is that this one is easily re-configurable. This allowed them to test many geometries, in the hopes of providing data to make robust models that are accurate across a range of vehicle shapes.Saxton-Fox and her Ph.D.

Ancient metal cauldrons give us clues about what people ate in the Bronze Age -- ScienceDailyArchaeologists have long been drawing conclusions about how ancient tools were used by the people who crafted them based on written records and context clues. But with dietary practices, they have had to make assumptions about what was eaten and how it was prepared. A new study analyzed protein residues from ancient cooking cauldrons and found that the people of Caucasus ate deer, sheep, goats, and members of the cow family during the Maykop period (3700--2900 BCE).

Neuroscientists successfully test theory that forgetting is actually a form of learning -- ScienceDailyNeuroscientists report the first results from experimental tests designed to explore the idea that 'forgetting' might not be a bad thing, and that it may represent a form of learning -- and outline results that support their core idea. Seemingly lost memories can be retrieved and updated by environmental cues, which means this research has implications for a range of diseases such as Alzheimer's.
