New Study Maps How Pesticides Alter Human Gut Bacteria

While emerging evidence suggests pesticides can be toxic to the mix of microorganisms in the digestive system, a new study is the first to map changes to specific gut bacteria based on interactions between human microbes and insect-killing chemicals observed in the lab and an animal model.

Study Finds Protein Cleavage Essential for Healthy Cilia and Cell Signaling

New research by Sumeda Nandadasa, PhD, reveals how a key protein associated with Meckel-Gruber syndrome, nephronophthisis, Joubert syndrome and other ciliopathies is cut in half to perform two separate functions, both of which are fundamental to the healthy development of children.

Reactivating a Genetic Switch Restores Ear Regeneration in Mice

By flipping an evolutionarily disabled genetic switch involved in Vitamin A metabolism, researchers have enabled ear tissue regeneration in mice. Unlike some animals such as fish and salamanders, mammals have limited capacity to regenerate damaged tissues or organs fully.
