CORRECTS YEAR - In this April 19, 2018, photo, volcanic smoke billows from Mt. Io, foreground, part of the Kirishima mountain range on Japan’s southern main island of Kyushu, taken over Ebino city, Miyazaki prefecture. The Meteorological Agency said Friday, April 20, 2018 that Mt. Io erupted for the first time since 1768, spewing smoke and ash high into the sky. The agency has expanded a no-go zone to the entire mountain from just around the volcano’s crater. At back is Shinmoedake volcano. (Kyodo News via AP)

This photo released by SpaceX on Wednesday, April 18, 2018 shows a Falcon 9 rocket carrying NASA's Transiting Exoplanet Survey Satellite at Cape Canaveral Air Force Station in Fla. Once in orbit, TESS will peer at hundreds of thousands of bright neighboring stars, seeking planets that might support life. (SpaceX via AP)

This undated microscope image provided by the American Society for Reproductive Medicine in January 2018 shows a trophectoderm biopsy, in which cells from the outer layer of an embryo that develop into the placenta and amniotic membranes are removed and can be used for genetic testing. When a couple is known to be at risk for having a child with a specific genetic disorder, the woman undergoes a procedure to remove some of her eggs. After fertilization, some cells can be plucked from the embryos and examined to identify those without carry the disease-causing abnormality. (ASRM via AP)Wedn

FILE - This 2013 file photo provided by the U.S. Fish and Wildlife shows nectar-feeding lesser long-nosed bats attracted to a hummingbird feeder during a citizen science bat migration monitoring project in southern Arizona. Wildlife managers in the American Southwest say a once-rare bat important to the pollination of plants used to produce tequila has made a comeback and is being removed from the federal endangered species list.

FILE- In this April 23, 2015, file photo a sparrow hawk looks up after catching a pigeon on a falcon farm, near the northern Serbian town of Coka. A study published Monday, April 16, 2018, in the Proceedings of the National Academy of Sciences gives the first global look at a worsening timing problem. For example in the Netherlands, the Eurasian sparrow hawk has been late for dinner because its prey, the blue tit, over 16 years has arrived almost six days earlier than the hawk.
