Scientists turn yeast cells into drug factories

Stanford engineers have genetically reprogrammed the cellular machinery of yeast to create microscopic factories that convert sugars and amino acids into plant-based drugs.

A new optical system shows how decisions light up the brain

A technique called COSMOS will help researchers understand how our brains work and aid in the development of new drugs. The inventors have created an instructional website to help other researchers build their own relatively-inexpensive COSMOS systems.

Experimental two-in-one shot could aid diabetics

Researchers have developed a way to combine insulin with a second hormone known as amylin, to create a two-in-one injection that could, if proven safe and effective in human trials, make it easier for diabetics to more effectively control their blood sugar levels.

The hidden pattern that drives brain growth

Using microscopy and mathematics, researchers have discovered the invisible pattern that growing neurons follow to form a brain. The technique could one day allow bioengineers to coax stem cells to grow into replacement body parts.
