Sorting and secreting insulin by expiration date

A study in the Journal of Biological Chemistry describes a new way to determine the age of insulin-storage parcels, known as granules, and sheds light on how their age affects their release into the bloodstream. The findings ...

Diabetes in mice cured rapidly using human stem cell strategy

Researchers have converted human stem cells into insulin-producing cells and demonstrated in mice infused with such cells that blood sugar levels can be controlled and diabetes functionally cured for nine months.

Signaling factor seeking gene

During embryonic development, stem cells begin to take on specific identities, becoming distinct cell types with specialized characteristics and functions, in order to form the diverse organs and systems in our bodies. Cells ...

Directed evolution opens door to new antibiotics

In the ongoing arms race with humans and their antibiotics on one side, and bacteria with their ability to evolve defenses to antibiotics on the other, humans have enlisted a new ally—other bacteria.
