Stem cells can repair Parkinson's-damaged circuits in mouse brains
University of Wisconsin-Madison researchers demonstrated a proof-of-concept stem cell treatment in a mouse model of Parkinson's disease. They found that neurons derived from stem cells can integrate well into the correct regions of the brain, connect with native neurons and restore motor functions.

Biocrust as one of multiple stable states in global drylands
Biocrusts cover ~30% of global drylands with a prominent role in the biogeochemical cycles. Theoretically, biocrusts, vascular plants, and bare soil can represent multiple stable states in drylands.
