Insulin-producing cells grown from patient’s blood safe for transplant

Researchers achieve milestone in efforts to get patients with diabetes off injected insulin for good

Insulin-producing cells grown from patient’s blood safe for transplantDiabetes researchers are reporting early success in a first-in-humans clinical trial to test whether pancreatic cells grown from a patient’s own blood can be safely implanted and begin to produce insulin.

Many animals use mimicry to fool predators and prey into thinking they’re something else, with insects putting on the best show in this regard. Tens of thousands of species of insects aren’t what they seem at first glance. But…

Promising chemotherapy treatment for bladder cancer enters human trials

A rejected patent application nearly derailed years of research, but support from experts saved the day

Promising chemotherapy treatment for bladder cancer enters human trialsIn 2015, University of Alberta cancer researcher Jack Tuszynski learned that his patent application for a promising chemotherapy treatment for people suffering from metastatic bladder cancer had been rejected by the U.S. Patent Office. “That was it. I thought, ‘We can’t proceed, we’re done, we spent almost a decade working on this and it’s a no go,’”…

Fossil thought to be missing link between lizards, snakes debunked

Research bringing us closer to a cure for diabetes

November is National Diabetes Awareness Month

Research bringing us closer to a cure for diabetesAs part of the celebrations, we're revisiting five great stories showcasing the breadth of work being done at the University of Alberta in the journey towards a cure.

Study points to way to reducing many of the negative effects of HIV

Could lead to new treatments

Study points to way to reducing many of the negative effects of HIVIn a groundbreaking study of people living with HIV, University of Alberta researchers found that elusive white blood cells called neutrophils play a role in impaired T cell functions and counts, as well as the associated chronic inflammation that is common with the virus. Neutrophils are a foundational part of the body’s immune system and…

Raptors on the move are a sight to behold
