Young Stem Cell Scientists Struggle for Funding – A study led by government scientists showed that middle-aged and older stem cell researchers are crowding out younger scientists in competition for federal grants.

Zika Virus Disrupts Neural Progenitor Development and Leads to Microcephaly in Mice – Researchers found that Asian Zika virus (ZIKV) strain SZ01 replicates efficiently in embryonic mouse brain by directly targeting different neuronal linages and that ZIKV infection leads to cell-cycle arrest, apoptosis, and inhibition of neural progenitor cell differentiation, resulting in cortical thinning and microcephaly.

A Stem Cell Therapy to Replace Root Canals? – Scientists from the University of Nottingham and Harvard University's Wyss Institute are developing a new treatment strategy that could someday help heal a damaged tooth using the patient's own stem cells.

A New Model of Autism Using Stem Cells – Researchers at the Salk Institute turned skin cells of people with autism spectrum disorder into neurons, showing specific defects compared with those neurons derived from healthy people.
