How We Go from Animal Model to Clinical Trial
Testing new treatments in other animals can help us spot complications or potential pitfalls, but the results don’t always carry over to humans, which means that safely going from animal to human trials is a lot more complicated than you...

Why Do Corgi Mixes Always Look Like Corgis?
Humans have had a soft spot for these furry little mutants ever since our friendship with dogs began, but why is it that Corgi mixes often just look like a Corgi that’s wearing a costume?

TED: A new superweapon in the fight against cancer | Paula Hammond
Cancer is a very clever, adaptable disease. To defeat it, says medical researcher and educator Paula Hammond, we need a new and powerful mode of attack. With her colleagues at MIT, Hammond engineered a nanoparticle one-hundredth the size...
