How signals get inside cancer cells and spur aggressive growth

The outside of a cancer cell is bombarded by signals. They come from the immune system, supporting tissues and other structures. But how do those signals impact cancer? A new study provides a surprising model of the process by which those signals enter and influence the cell. The finding could open up a potential new avenue to pursue new therapies against cancer. "How those signals enter the inside of the

Tiny Nanopackages Built Out of DNA Help Scientists Peek at How Neurons Work

A team of scientists from the University of Chicago designed a way to use microscopic capsules made out of DNA to deliver a payload of tiny molecules directly into a cell. The technique, detailed Aug. 21 in Nature Nanotechnology, gives scientists an opportunity to understand certain interactions among cells that have previously been hard to track. “It’s really a molecular platform,” said Yamuna Krishnan, professor in chemistry and co-author of

Researchers: Insulin Pill Could Make Diabetes Treatment ‘Ouchless’

Every day, millions of Americans with diabetes have to inject themselves with insulin to manage their blood-sugar levels. But less painful alternatives are emerging. Scientists are developing a new way of administering the medicine orally with tiny vesicles that can deliver insulin where it needs to go without a shot. Today, they share their in vivo testing results. The researchers are presenting their work at the 252nd National Meeting &
