Mar. 9, 2017—Research into retinal regeneration in zebrafish has identified a signal that appears to trigger the self-repair process, raising the possibility of inducing retinal repair in human eyes.
Feb. 27, 2017—Genes used by the insect parasite Wolbachia to control its hosts' reproduction can be used to help control the spread of mosquito-borne diseases like dengue, Zika and malaria.
Feb. 22, 2017—Scientists at Vanderbilt University have created a three-dimensional organ-on-a-chip that can mimic the heart’s amazing biomechanical properties in order to study cardiac disease, develop heart drugs.
Feb. 14, 2017—Professor Emeritus of Chemistry David James Wilson died peacefully Jan. 12 in Belleville, Michigan, following a three-year bout with melanoma. He was 86.
Jan. 26, 2017—A new study has compared the diet of a variety of Australian megafaunal herbivores from the period when they were widespread (350,000 to 570,000 years ago) to a period when they were in decline (30,000 to 40,000 years ago) by studying their fossil teeth. The analysis suggests that climate change had a significant impact on their diets and may well have been a primary factor in their extinction.
