Construction Begins On $1 Billion Telescope That Will Take Pictures 10 Times Sharper Than Hubble's (qz.com)
The $1 billion Giant Magellan Telescope in Chile is officially under construction with a scheduled date of operation in 2024. The telescope "will have an array of seven enormous mirrors totaling 80 feet in diameter, giving it 10 times the precision of the Hubble telescope," reports Quartz. "Among its advances is technology to help it correct for the distorting effect of Earth's atmosphere by using software to make hundreds of adjustments per second to its array of secondary mirrors." From the report: The project's architects, a consortium of universities and institutions in the U.S., Korea, and Australia, chose to build in Chile's Atacama desert for its clear, dry skies. Astronomers will use the Magellan Telescope to study the origins of elements and the birth of stars and galaxies, and to examine planets that have been identified as potentially harboring life. Mother Nature Network has an article highlighting nine of the largest new telescopes expected to begin operation in the next decade. -
From Bicycles To Washing Machines: Sweden To Give Tax Breaks For Repairs (mnn.com)
jenningsthecat writes: The Swedish government is putting its money where its mouth is when it comes to encouraging the repair of stuff that would otherwise be thrown away, according to both The Guardian and Fast Company. The country's Social Democrat and Green party coalition have submitted proposals to Parliament that would reduce the value-added-tax (VAT) on bicycle, clothing, and shoe repairs from 25% to 12%. Also proposed is an income tax deduction equalling half the labor cost of repairing household appliances. According to The Guardian, "the incentives are part of a shift in government focus from reducing carbon emissions produced domestically to reducing emissions tied to goods produced elsewhere." Per Bolund, Sweden's Minister for Financial Markets and Consumer Affairs, said the policy also tied in with international trends around reduced consumption and crafts, such as the "maker movement" and the sharing economy, both of which have strong followings in Sweden. The VAT cut may create more jobs for immigrants as it could spur the creation of a new home-repairs service industry. Also, from a science standpoint, the incentives could help cut the cost of carbon emissions on the planet as it should in theory reduce emissions linked to consumption. "I believe there is a shift in view in Sweden at the moment. There is an increased knowledge that we need to make our things last longer in order to reduce materials' consumption," Bolund said. The Guardian's report concludes: "The proposals will be presented in parliament as part of the government's budget proposals and if voted through in December will become law from January 1, 2017." -
What's Stopping Us From Eating Insects?
Lasrick writes "Scientific American has a really nice article explaining why insects should be considered a good food source, and how the encroachment of Western attitudes into societies that traditionally eat insects is affecting consumption of this important source of nutrients. Good stuff." Especially when they're so easy to grow. -
The Science of Thanks Giving
Hugh Pickens writes "This is Americans' big week to give thanks. Now Russell McLendon writes that giving thanks can do wonders for the human brain according to researchers at UC Berkeley's Greater Good Science Center where scientists have developed an easy way for people to do just that and, at the same time, contribute to a national research project and maybe also improve their lives. The project is part of a $5.6 million, three-year national effort called 'Expanding the Science and Practice of Gratitude,' funded by the John Templeton Foundation. The center has gone live with Thnx4.org, an interactive, shareable gratitude journal and has invited people in the campus community to take part in the Cal Gratitude Challenge by keeping a two-week online 'gratitude journal' and, if they choose, sharing their posts with others. Early research into the power of gratitude journals ended up proving that students who wrote down everything they were grateful for strengthened their overall resilience and became less vulnerable to everyday stresses and complaints like rashes and headaches, says Emiliana Simon-Thomas. 'Thnx4.org wanted to make this spiral notebook very accessible, and to make the research a little more specific than it has been historically,' says Simon-Thomas. Online, anyone can take part — and potentially reap the benefits. The Cal Gratitude Challenge opened November 1 and will remain open throughout November but the project has a three-year grant and participants will be able to maintain their journals for the duration and first results from the data are expected in January. 'We affirm that there are good things in the world, gifts and benefits we've received,' writes Robert Emmons as part of the project. 'This doesn't mean that life is perfect; it doesn't ignore complaints, burdens, and hassles. But when we look at life as a whole, gratitude encourages us to identify some amount of goodness in our life.'" -
NASA Craft To Leave Vesta Heads For Dwarf Planet Ceres
DevotedSkeptic writes "NASA's Dawn probe is gearing up to depart the giant asteroid Vesta next week and begin the long trek to the dwarf planet Ceres, the largest object in the asteroid belt. The Dawn spacecraft is slated to leave Vesta on the night of Sept. 4 (early morning Sept. 5 EDT), ending a 14-month stay at the 330-mile-wide (530 kilometers) body. The journey to Ceres should take roughly 2.5 years, with Dawn reaching the dwarf planet in early 2015, researchers said. 'Thrust is engaged, and we are now climbing away from Vesta atop a blue-green pillar of xenon ions,' Dawn chief engineer and mission director Marc Rayman, of NASA's Jet Propulsion Laboratory in Pasadena, Calif., said in a statement. 'We are feeling somewhat wistful about concluding a fantastically productive and exciting exploration of Vesta, but now have our sights set on dwarf planet Ceres.'" -
Genghis Khan, History's Greenest Conqueror
New research suggests that in addition to being one of history's cruelest conquerors, Genghis Khan may have been the greenest. It is estimated that the Mongol leader's invasions unintentionally scrubbed almost 700 million tons of carbon from the atmosphere. From the article: "Over the course of the century and a half run of the Mongol Empire, about 22 percent of the world's total land area had been conquered and an estimated 40 million people were slaughtered by the horse-driven, bow-wielding hordes. Depopulation over such a large swathe of land meant that countless numbers of cultivated fields eventually returned to forests. In other words, one effect of Genghis Khan's unrelenting invasion was widespread reforestation, and the re-growth of those forests meant that more carbon could be absorbed from the atmosphere." I guess everyone has their good points. -
Study Finds Most Would Become Supervillians If Given Powers
It probably comes as no surprise, but researchers have found that most of us would gladly put on a mask and fight do-gooders if given super powers. From the article: "But power also acts like strong cologne that affects both the wearer and those within smelling distance, Galinsky noted. The person gains an enhanced sense of their importance, and other people may regard them with greater respect as well as extend leniency toward their actions. That combination makes for an easy slide into corruption." -
Researchers Test Space Beer
With space tourism becoming a real possibility in the near future, brewers are trying to figure out how to provide a good beer in space. To this end, a non-profit space research corporation Astronauts4Hire will begin testing an Australian brew created to be enjoyed in microgravity. From the article: "In the past, NASA has also sponsored studies on space beer, and whether or not the popular beverage can be brewed in space. Under current policies, however, alcohol remains forbidden on the International Space Station." -
Silicon As the New Lithium
hduff writes "While lithium-ion batteries offer better performance than lead-acid or ni-cad batteries, the supply of lithium is limited and the batteries can pose problems. Researchers at the Technion-Israel Institute are building a better battery with easily obtainable sand and air."
