At the center of our galaxy, in the immediate vicinity of its supermassive black hole, is a region wracked by powerful tidal forces and bathed in intense ultraviolet light and X-ray radiation. These harsh conditions, astronomers surmise, do not favor star formation, especially low-mass stars like our Sun. Surprisingly, new observations from the Atacama Large Millimeter/submillimeter Array (ALMA) suggest otherwise.

Ask someone to draw a tree and they will invariably draw a trunk and branches—leaving the roots out of the picture. In a unique study of tropical tree roots at the Smithsonian Tropical Research Institute published in PLOS ONE, roots accounted for almost 30 percent of the total biomass of young trees. The authors hope that future estimates of carbon storage and water-use by tropical forests will include information on root biomass and architecture.

In March 2017, a research team led by Matthew Baron of the University of Cambridge published a study in Nature. The scientists had proposed a radical revision on the understanding of the early evolution of dinosaurs and the family tree relationship among them. They suggested that the traditional classification between Ornithischia –bird hipped- and Saurischia – lizard hipped-, was modified.

An international research team working at the Smithsonian Tropical Research Institute in Panama knocked out a single control gene in the DNA of seven different butterfly species. In the Sept. 18 Proceedings of the National Academy of Sciences early online edition, they reveal the surprising results of rewiring the WntA gene: a single gene influences the exuberant diversity of butterfly wing patterns in nature.
