On Dec. 21, NASA's Juno spacecraft will be 3,140 miles (5,053 kilometers) above Jupiter's cloud tops and hurtling by at a healthy clip of 128,802 mph (207,287 kilometers per hour). This will mark the solar-powered spacecraft's halfway point in data collection during its prime mission. from Latest Science News -- ScienceDaily https://ift.tt/2A4Zgmj

Thyalacoleo carnifex, the 'marsupial lion' of Pleistocene Australia, was an adept hunter that got around with the help of a strong tail, according to a new study. These insights come after newly discovered remains, including one nearly complete fossil specimen, allowed these researchers to reconstruct this animal's entire skeleton for the first time. from Latest Science News -- ScienceDaily https://ift.tt/2SIyJBX

In 2016, Seattle Public Schools pushed back start times for its 18 high schools by 55 minutes. Researchers have now announced that, as a result, teens at two Seattle high schools got more sleep on school nights -- a median increase of 34 minutes of sleep each night -- and showed improved attendance and grades. from Latest Science News -- ScienceDaily https://ift.tt/2EqrmvX

Stethoscopes carried by health care practitioners are loaded with diverse bacteria, including some that can cause healthcare-associated infections, according to a study. The research also reviewed the effectiveness of cleaning methods, finding a standardized approach to be superior for removing bacteria compared with various approaches employed by health care practitioners. from Latest Science News -- ScienceDaily https://ift.tt/2QSi41q
