Stem cell transplants repair macular holes in primate study

Human stem cell transplants successfully repaired macular holes in a monkey model, researchers report October 3 in the journal Stem Cell Reports. After transplantation, the macular holes were closed by continuous filling ...

Study hints at ways to generate new neurons in old brains

Most neurons in the human brain last a lifetime, and for good reason. Intricate, long-term information is preserved in the complex structural relationships between their synapses. To lose the neurons would be to lose that ...

Diabetes

A new injectable shows promise to prevent and treat hypoglycemia

People with diabetes take insulin to lower high blood sugar. However, if glucose levels plunge too low—from taking too much insulin or not eating enough sugar—people can experience hypoglycemia, which can lead to dizziness, ...
