A Northwestern University team is the first to demonstrate a method that delivers cells [...]

“The vein density of leaves within the flowering plants is much, much higher than all other plants,” said the study’s lead author, C. Kevin Boyce, Associate Professor in Geophysical Sciences at the University of Chicago. “That actually matters physiologically for both taking in carbon dioxide from the atmosphere for photosynthesis and also the loss of water, which is transpiration.”

The researchers show that insulin-secreting islet cells in the pancreas, called beta-cells, have their own dedicated clock. The clock governs the rhythmic behavior of proteins and genes involved in insulin secretion, with oscillations over a 24-hour cycle.

But on Sunday, a new leader appeared among the street performers and protesters. Nobel prize-winning physicist, Leon Lederman camped out there behind an impromptu desk to field questions pedestrians had about science or anything else. Lederman, director emeritus of the Fermi National Accelerator Laboratory [...]

While some onlookers had no idea who Lederman was, several star-struck visitors had made a special trip downtown to meet the physicist.
