How did the moon get its bull's-eye crater?
One of the most striking features on the moon is Orientale Basin, a 580-mile-wide bull's-eye crater surrounded by three concentric rings – and scientists now think they know exactly how it formed.In a joint pair of articles published in the current issue of Science, researchers explain how they used data from NASA's Gravity Recovery and Interior Laboratory (GRAIL) spacecraft to peer beneath the moon's surface and piece together the giant crater's story."Big impacts like the one that formed Orie..>> view originalHumans killed nearly two-thirds of the world's wildlife over...
By the end of the decade, global wildlife populations could be just one-third of what they were 50 years ago because of humans, scientists warned in a World Wildlife Fund report released Thursday. According to the Living Planet Report 2016, populations of fish, birds, mammals, amphibians and reptiles declined 58 percent between 1970 and 2012, the most recent year for which data is available. The report tracks more than 14,000 populations of more than 3,700 species. "Wildlife is disappearing ..>> view originalLiving life on high: swift birds eat, sleep, and mate without touching Earth
A 10-hour flight can leave humans longing for solid ground beneath their feet, but for some birds that might not be the case – even after months, not hours, on the wing. The common swift, Apus apus, spends 10 months of the year aloft, according to research published Thursday in the journal Current Biology. This new study makes the bird a record-setter. Previous research had pointed to the Alpine swift, Tachymarptis melba, as being able to fly non-stop for some 200 days, 100 days less than the c..>> view original[ October 27, 2016 ] Final Pluto data transmission received from flyby probe News

Credit: NASA/JHUAPL/SWRI The last bits of data collected during NASA’s New Horizons spacecraft’s speedy flyby of Pluto last year are back on Earth, scientists said Thursday, marking the official end of the probe’s prime mission. It took more than a year for New Horizons to send back the 50-plus gigabits of data collected around the time the spacecraft zipped by Pluto and its ..>> view originalResearchers have found the first fossilized dinosaur brain
Fossilized dinosaur brain. Jamie Hiscocks Dinosaur fossils aren’t always the mineralized remnants of bones. Every now and then, you get an impression of a footprint, or the trace outlines of a feathered arm or “wing.” Sometimes, paleontologists strike proverbial gold and find a segment of dinosaur tissue, including skin, capillaries, and – as revealed in an incredible special publication by the Geological Society of London – even a brain. A fossil hunter, searchi..>> view originalAncient Chimps and Bonobos Hooked Up
Chimpanzees and bonobos are two species separated by about 2 million years and one impassible river that divides their range. New research, however, reveals that these two great-ape species mixed their genes in the ancient past. In at least two separate events, about 200,000 and 500,000 years ago, chimpanzees (Pan troglodytes) interbred with bonobos (Pan paniscus), researchers report today (Oct. 27) in the journal Science.Chimps and bonobos split off from a common ancestor between 1.5 million an..>> view originalNations Agree To Establish World's Largest Marine Reserve In Antarctica

Some 16,000 years ago a big cat died. Today, its toes may provide insight into its species' extinction.The cave lion, Panthera spelaea, once roamed from Europe to northern North America. Scientists think the animal was much like its modern African counterpart and hunted large animals like deer and bison. But about 12,000 ago or so, cave lions vanished from the landscape. Scientists have suggested that changes in climate drove P. spelaea to extinction, but a study published Wednesday in the jour..>> view originalThis Is the Best View Yet of Europe's Mars Lander Crash Site
Europe's ExoMars lander gauged out a crater 1.6 feet (0.5 meters) deep and nearly 8 feet (2.4 m) wide when it crashed into the Red Planet's surface last week, a new photo by a NASA Mars orbiter reveals. The lander, known as Schiaparelli, apparently deployed its parachute prematurely and didn't fire its thrusters nearly long enough to pull off a soft landing as planned on Oct. 19, European Space Agency (ESA) officials have said. The new image, which was captured by NASA's Mars Reco..>> view originalThe male birth control shot looks promising, but needs work
