Hubble spots evidence of water plumes on Jupiter's moon Europa

Astronomers on Monday said they have spotted evidence of water vapor plumes rising from Jupiter's moon Europa, a finding that might make it easier to learn whether life exists in the warm, salty ocean hidden beneath its icy surface. The apparent plumes detected by the Hubble Space Telescope shoot about 125 miles (200 km) above Europa's surface before, presumably, raining material back down onto the moon's surface, NASA said. Europa, considered one of the most promising candidates for life in the solar system beyond Earth, boasts a global ocean with twice as much water as in all of Earth's seas hidden under a layer of extremely cold and hard ice of unknown thickness.

In Shift, Most Americans Now Say President Should Release All Medical Records

A majority of Americans now say that a U.S. president should release all of his or her medical information. The poll, which was conducted by Gallup last week, found that a slim majority of Americans, 51 percent, said that a president should release all medical information that might affect that person's ability to serve in office, whereas 46 percent said that a president should have the right to keep those medical records private. The new poll results are a change from the results in 2004, when just 38 percent of Americans said that a president should release all of his or her medical information, and 61 percent said that a president should be able to keep those records private, according to Gallup.

Drug Overdose Cluster in Canada Tied to Opioid-Laced Cocaine

More than 40 people in a Canadian city were treated for an opioid overdose this summer after they smoked crack cocaine that had been contaminated with an opioid drug related to fentanyl, according to a new report. In mid-July, a hospital in the city of Surrey, British Columbia, experienced a large spike in patients needing treatment for an opioid overdose — about 11 patients per day needed treatment, up from the usual four patients per day. Most of the patients had become unconscious after smoking what they thought was crack cocaine, the report said.

Early Cats Traveled with Vikings and Farmers

The early origins of domesticated cats are shrouded in mystery, but a new genetic analysis suggests that felines traveled the world with farmers and Vikings. The News section of Nature reports that the broadest genetic analysis to date of ancient cats reveals two waves of cat expansion. The second wave of expansion started in Egypt — where cats had religious significance and were often mummified — and spread by sea to Eurasia and Africa.

Ring-Shaped Geoglyphs Found Near Ancient Town in Peru

Dozens of circular geoglyphs, some comprising several intertwined rings, have been identified and mapped near the ancient Peruvian town of Quilcapampa, revealing that these earthen designs were created near ancient pathways used for trade. Geoglyphs are designs, which often form shapes or images, on the landscape. The newly mapped geoglyphs may have had symbolic significance, possibly representing the flow of people and goods through the town at the time, according to Justin Jennings, a curator at the Royal Ontario Museum in Toronto who is one of the team leaders.

U-2 Spy Plane Crash: Why 'Cold War' Aircraft Are Still Relevant Today

A U-2 spy plane that crashed in northern California earlier this week, killing one of the two pilots, focused attention on a normally clandestine aspect of the U.S. military. The U-2 plane has a long and storied history that stretches back to the late 1950s, but how is the reconnaissance aircraft used today? U-2 planes have been flown by the United States and other nations for more than 60 years, as both a spy plane and an instrument of science.

Scientists find new fat clues in faeces

By Kate Kelland LONDON (Reuters) - Scientists in Britain have found a new link between the diversity of bacteria in human poo - the human fecal microbiome - and levels of harmful types of body fat. In research that may help explain why excessive weight problems and obesity tend to run in families, the scientists said high levels of visceral fat - which is linked to risks of chronic disease - were linked to having a relatively small range of bacteria in faeces. People with a high diversity of bacteria in their faeces had lower levels of visceral fat, according to the study published on Monday in the journal Genome Biology.
