Understanding New Brain Research Models
Scientists can now grow living human brain tissue in lab dishes and in animals, creating organoids, neural transplants, and chimeras. While these models will help us better understand the brain in health and disease, they also raise thorny ethical questions that will only get thornier in the future.
Understanding the Mechanisms Underlying Vocal LearningQ&A with Michael Yartsev, Ph.D.
Most mammals know from birth how to make sounds that communicate, but not humans. And not bats: Dana grantee Michael Yartsev has collected reams of data on how Egyptian fruit bats learn to make sounds to communicate as a way to understand how we do it.
Why Studies of Fighting Fruit Flies Are Relevant to Understanding Human AggressionReport on Progress
It may surprise some people to learn that fruit flies fight. But male Drosophila melanogaster (more accurately called “vinegar flies”) do fight–to gain access to resources such as food or females.
Scientists in BunkersHow Appeasement of “Animal Rights” Activism Has Failed
These neuroscientists warn that propaganda, political pressure, and outright violence by opponents of animal research now threaten to curtail progress in fields from behavior to psychopharmacology, from addiction to stroke.
