With this new knowledge, NTU is looking to collaborate with the industry on... Read More
A new study shows that two unusual treatment approaches may have beneficial effects on the symptoms of autism in children and adults with the disorder. Using a hot bath to raise body temperature and thereby mimic the effects of infection, or using worm eggs to stimulate the production of immunor... Read More
