Study Casts Doubt on Theory That Legal Hunting Reduces Poaching

Authors of a study on wolves in Wisconsin and Michigan say they have quantitative evidence that government authorization of legal killing of wolves appears to also increase illegal killing. Credit Tim Fitzharris/Minden Pictures Government wildlife authorities and some conservation groups have for years argued that allowing some legal hunting can help reduce the illegal killing of threatened carnivores like wolves and grizzly bears.Their theory..>> view originalAncient axe find shows Australians have long been tech innovators
Australians have long been early adopters of technology, and an important archeological find only confirms it. Archeologists have identified a tiny axe fragment dating back to between 45,000 to 49,000 years ago in the Kimberley region of Western Australia. Not only could it be the world's oldest known axe, it shows the first Australians were some serious technological innovators. The report was published Monday in the journal, Australian Archaeology. While the fragment was excavated and dated i..>> view originalNASA Finds 1284 Alien Planets, Biggest Haul Yet, with Kepler Space Telescope
The number of known alien planets has just gone up by more than 60 percent. NASA's Kepler space telescope has discovered 1,284 new exoplanets, including nine rocky worlds that might be capable of supporting life as we know it, astronomers announced today (May 10). This is by far the largest haul of alien planets ever unveiled at one time. The total exoplanet tally now stands at about 3,200, and Kepler has found 2,235 of them, NASA officials said. [1,284 Exoplanets Found: NASA's Keple..>> view originalWatch global warming spiral out of control in this new climate visualization
A climate scientist in the UK has devised a new way of visualizing the progression of human-caused global warming, and it is one that you've likely never considered before. Ed Hawkins, a climate scientist at the National Center for Atmospheric Science at the University of Reading, devised the spiral animation to show how global average surface temperatures are increasing relative to the average temperature during preindustrial times. "I wanted to try and visualise the changes we have seen in ..>> view originalScientists have detected oxygen on Mars - and it could reveal something fascinating about the planet's past
Thomson Reuters For the first time in four decades, a team of researchers has found atomic oxygen lingering in the upper Martian atmosphere. But don't get carried away too quickly — atomic oxygen is very different from the stuff we breathe. But it does affect how easily gases escape the Martian atmosphere, so these measurements will likely help uncover more about why and how the protective gases enveloping Mars eroded over the last few billions of years. If Mars ever supported life, those gases..>> view originalArtificial intelligence: Key to Kentucky Derby betting?
You probably didn't consider basing your Kentucky Derby bets on artificial intelligence -- but maybe you should have. The artificial intelligence company Unanimous tested its new software platform, UNU, on last weekend's Kentucky Derby, as reported by TechRepublic. Twenty participants, convened by the company, first used the software to narrow the field of 20 horses down to four top picks. The participants then used UNU to predict the winning order -- and it turned out to be 100 percent correct..>> view originalFacebook identifies one of 2030 new plants found in 2015
More than 300 years since a Swedish scientist called Carl Linnaeus published the first book describing 100 types of plant, biologists are still discovering new species.Last year, experts officially classified 2,034 plants that had never before been seen. The new finds include a huge insect-eating sundew discovered via Facebook, five new types of onion, a 10ft-tall (3 metre) slipper orchid and a close relative of the sweet potato.However, the report also warned that a fifth of all types of plants..>> view original'Breathing' Volcano: How Scientists Captured This Awesome Animation
Mount Etna seems to breathe in a NASA animation showing how changes in the volcano's magma chamber deform the ground around the mountain. Mount Etna is an active volcano on the Italian island of Sicily. Its last eruption — a small one — occurred on March 31, according to the Smithsonian Institution's Global Volcanism Program. Reports of Etna's rumblings date back thousands of years. The Greek historian Diodorus Siculus wrote of Etna's eruptions in his "Bibliotheca historica," a series of ..>> view originalNASA releases dozens of patents into the public domain
NASA NASA has released 56 of its previously patented technologies to the public domain for unrestricted commercial use. The released patents are completely free to use and don't require any licensing agreements with the US space agency."These technologies were developed to advance NASA missions but may have non-aerospace applications and be used by commercial space ventures and other companies free of charge, el..>> view originalAncient trade routes written in camel genes
