Plumes of ocean spray are emanating from Jupiter's moon Europa

May 14 (UPI) -- New research offers additional evidence of plumes emanating from Europa's subsurface ocean. Images captured by the Hubble Telescope have previously suggested the presence of ocean plumes ejected through tissues in the icy crust of Jupiter's moon. Some astronomers were skeptical of the Hubble results, however. The newest proof was discovered among data collected by the Galileo mission in 1997 during a Europa flyby. Scientists detailed the new proof in a paper published Monday in the journal Nature Astronomy. Scientists with the Cassini mission were able to identify water plumes protruding from Saturn's moon Enceladus by measuring perturbations in the magnetic fields surrounding the satellite. Molecules and atoms ejected in a watery plume quickly become ionized as solar win...

FRIDAY, Oct. 6, 2017 -- Discontinuation of the pain-free nasal spray flu vaccine hasn't led to a drop in childhood influenza vaccination -- at least not in Oregon.In 2016, the U.S. Centers for Disease Control and Prevention's advisory committee on vaccines reported that the nasal spray vaccine, FluMist, was ineffective and advised against its use.Doctors and health officials then feared that with only an injectable vaccine available, needle-shy parents might avoid getting their children vaccinated, said Steve Robison, who is with the Oregon Health Authority.However, "worry that the withdrawal of the nasal spray vaccine recommendation would lead to a large drop in influenza immunization rates for children was unfounded," said Robison, who led a study on the recommendation's aftereffects.Pro...
