Mark McClusky says for elite athletes today, pushing boundaries and breaking records is all about "the aggregation of marginal gains."
Researchers have successfully treated three leukemia patients using a new type of therapy. A year after the treatment, two of the patients remain cancer free.
The treatment involves extracting a patient’s blood, injecting a virus into his or her T cells, and then injecting the blood back into the patient, where the virus attacks the cancer cells. This therapy is not without side effects, but researchers say they’re getting closer to the “holy grail” of cancer treatment.
