An Epochal Discovery: A Habitable Planet Orbits Our Neighboring Star One hundred and one years ago this October, a Scottish astronomer named Robert Innes pointed a camera at a grouping of stars near the Southern Cross, the defining feature of the night skies above his adopted Johannesburg. He was looking for a small companion to Alpha Centauri, our closest neighboring star system. Hunched over glass photographic plates, Innes teased out a signal. Across five years of images, a small, faint star moved, wiggling on the sky. It shifted just as much as Alpha Centauri, suggesting its fate was intertwined with that binary system.

12 Dozen Places To Educate Yourself Online For Free All education is self-education. Period. It doesn’t matter if you’re sitting in a college classroom or a coffee shop. We don’t learn anything we don’t want to learn. Pacific Islanders appear to be carrying the DNA of an unknown human species Hints of an unidentified, extinct human species have been found in the DNA of modern Melanesians - those living in a region of the South Pacific, northeast of Australia. According to new genetic modelling, the species is unlikely to be Neanderthal or Denisovan - two ancient species that are represented in the fossil record - but could represent a third, unknown human relative that has so far eluded archaeologists. "We’re missing a population, or we’re misunderstanding something about the relationships," Ryan Bohlender, a statistical geneticist from the University of Texas, told Tina Hesman Saey at Science News.

Academic Earth Thousands of video lectures from the world's top scholars. academicearth.org Ross Sea Designated as World’s Largest Marine Protected Area Today’s closing of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) meeting made history by declaring the largest marine protected area on the planet in Antarctica’s Ross Sea. This marks the first time that CCAMLR’s 24 member countries and the European Union reached consensus to protect this huge area of the Southern Ocean after similar proposals were blocked for the past five years. The 1.55 million square kilometer marine protected area will provide critical habitat, including breeding and foraging grounds, for a multitude of penguins, seals, krill, whales, and other species. It will also implement crucial policies needed to guide human activities such as fishing, shipping, and tourism, safeguarding this region, one of the last pristine oceans left on Earth. This would not have been possible without Russia joining with other countries to pass the proposal.

Open Educational Resources (OER): Resource Roundup Resources by Topic: OER, a part of the global open content movement, are shared teaching, learning, and research resources available under legally recognized open licenses -- free for people to reuse, revise, remix, and redistribute. Why are OER important? High-quality OER can save teachers significant time and effort on resource development and advance student learning inside and outside the classroom. The $100bn gold mine and the West Papuans who say they are counting the cost In 1936, Dutch geologist Jean Jacques Dozy climbed the world’s highest island peak: the forbidding Mount Carstensz, a snow-covered silver crag on what was then known as Dutch New Guinea. During the 4,800-metre ascent, Dozy noticed an unusual rock outcrop veined with green streaks. Samples he brought back confirmed exceptionally rich gold and copper deposits. Today, these remote, sharp-edged mountains are part of West Papua, Indonesia, and home to the Grasberg mine, one of the biggest gold mines – and third largest copper mine – in the world. Majority-owned by the American mining firm Freeport McMoRan, Grasberg is now Indonesia’s biggest taxpayer, with reserves worth an estimated $100bn (£80bn). But a recent fact-finding mission (by the Brisbane Archdiocese’s Catholic Justice and Peace Commission) described a “slow-motion genocide” (pdf) taking place in West Papua, warning that its indigenous population is at risk of becoming “an anthropological museum exhibit of a bygone culture”.

Ceremony Finally, there are more young Americans who 'believe' in evolution than creationism There’s been a long-standing divide between Americans who believe in evolution, and those who think God created humans just as they are. But a recent poll has shown that 51 percent of American adults under the age of 30 now claim to believe purely in secular evolution, which means evolution independent of any divine power – a jump from 40 percent back in 2009, when the research began. The survey was conducted by the Pew Research Centre back in July, and overall, the results were incredibly positive. Even though just over half the young people said that they believed solely in evolution as a result of natural selection, 73 percent said they expressed some sort of belief in evolution – which is 12 percent more than six years ago – as Rachel E. Gross reports for Slate.
