Great Barrier Reef authority warns of 'moderate to severe' bleaching
CORAL reefs off Cairns are “fluorescing” in a vivid neon-lit sign of the latest bleaching event on the Great Barrier Reef. Many of Queensland’s most popular tourist dive sites in the $6 billion-a-year Reef industry escaped a mass bleaching die-off last year.But record-breaking hot weather has reef experts warning of a “moderate to severe” impact from Townsville to Cairns.“It is bittersweet,” State Environment Minister Steven Miles said after snorkelling on Flynn and Moore reefs off Cairns yester..>> view originalDNA Results Help To Find Out The Secrets Of The Ancinent Pueblo
This is America's great southwest, a vast landscape with a long history of people who inhabited its canyons and flatters. Using DNA from skeletons excavated in New Mexico, scientists have discovered that more than a century years ago a dozen people buried in a small, hidden chamber. Chaco Research Archive described that in New Mexico's Chaco Canyon was one of the most influent cultures in the American Southwest. Pueblo Bonito was a beautiful town which is exactly located at the center of Chacoa..>> view originalNASA Image Reveals Saturn Moon Dione's Creusa Crater And Its Rays
The latest image released by NASA shows the heavily cratered surface of Saturn’s Moon Dione, lit from behind by the sun. The craters on Dione surface vary in size. However, the most prominent of them is crater Creusa which is about 36.2 kilometers across and leaves bright rays pattern almost all over the moon, hinting at the violent past of the Dione. “The rays are brighter material blasted out by the impact that formed the crater. Scientists can use the patterns of ejecta (like these rays), t..>> view originalSharks guardians of biodiversity: WA study

Astrophysicist Neil deGrasse Tyson has a tip for NASA. The 58-year-old cosmologist suggests naming the newly-discovered Earth-sized planets after the seven dwarfs from the 1812 fairy tale "Snow White." The 7 newly discovered Earth-sized planets orbit a “Red Dwarf” star, so perhaps they should each be named after the 7-dwarfs.— Neil deGrasse Tyson (@neiltyson) February 23, 2017 "The 7 newly discovered Earth-sized planets orbit a 'Red Dwarf' star, so perhaps they should be named after the 7 ..>> view originalArtificial synapse bridges the gap to brainier computers
The human brain is nature's most powerful processor, so it's not surprising that developing computers that mimic it has been a long-term goal. Neural networks, the artificial intelligence systems that learn in a very human-like way, are the closest models we have, and now Stanford scientists have developed an organic artificial synapse, inching us closer to making computers more efficient learners. In an organic brain, neuronal cells send electrical signals to each other to process and store inf..>> view originalBees learn new tricks from one another in world-first for insects

People intending to travel somewhere exotic – a region, for instance, without an abundance of working toilets – accept the necessity of sometimes painful vaccinations to protect them against nasty diseases.In years to come, as space travel becomes a viable option, pre-flight medical procedures are quite likely to become significantly more drastic. NASA scientist Carmel Johnston spent a year living in a Mars biosphere.

NASA's scientists think the conventional definition of planet has many flaws and propose to change it It has been more than a decade since Pluto was demoted from planet status, but scientists now think that it can be considered a planet once again, along with other 100 objects. This is only possible after defining the planets differently because of certain technical flaws in the definition adopted by the International Astronomical Union in 2016. The ‘mistakes’ can be a reason for a possib..>> view original
