Can a revolutionary gene-editing tool create better animal models for studying ALS?

Animal models enable scientists to study human diseases in lab settings. They help scientists learn about the biological changes that occur during disease onset and progression, and they can also speed the identification of promising therapies for testing in future clinical trials with human volunteers. In 2005, when he was still a graduate student, Dr. […]

How are two of the most common occurrences in ALS related?

Scientific discoveries are like puzzles. At first, two puzzle pieces may not appear to fit together, but then a new way of comparing them makes it possible to see how they connect, helping to fill in the picture. Mutations in the C9ORF72 gene are the most common genetic cause of ALS. Another abnormality that occurs […]

Can measuring “biological age” explain why ALS affects people differently?

ALS manifests very differently among people who develop the disease. It can occur anytime in adulthood. People usually only live two to five years after diagnosis, but it can range from six months to more than 20 years. Some people living with ALS, about 30 to 50 percent, experience cognitive or behavioural difficulties. Why does […]
