  • Coral Bleaching Is Spreading on the Great Barrier ReefCoral Bleaching Is Spreading on the Great Barrier Reef
    The Great Barrier Reef has been at risk for a year now following a 2016 coral bleaching event, but new findings show that after yet another bleaching event, two thirds of the reef have been severely damaged. The bleaching, a product of warming waters, causes the healthy corals to lose their algae and turn a […]
  • NASA’s Cassini Mission Prepares for ‘Grand Finale’ at SaturnNASA’s Cassini Mission Prepares for ‘Grand Finale’ at Saturn
    NASA’s Cassini spacecraft, in orbit around Saturn since 2004, is about to begin the final chapter of its remarkable story. On Wednesday, April 26, the spacecraft will make the first in a series of dives through the 1,500-mile-wide (2,400-kilometer) gap between Saturn and its rings as part of the mission’s grand finale. “No spacecraft has […]
  • Dinosaurs Likely Originated in United KingdomDinosaurs Likely Originated in United Kingdom
    {By Pallab Ghosh, BBC News} This is one of the conclusions of the first detailed re-evaluation of the relationships between dinosaurs for 130 years. It shows that the current theory of how dinosaurs evolved and where they came from may well be wrong. This major shake-up of dinosaur theory is published in this weeks’s edition of the […]
  • Trump’s NASA Bill Aims to Put People on MarsTrump’s NASA Bill Aims to Put People on Mars
    {By Sarah Kaplan, The Washington Post} President Trump just signed a bill authorizing $19.5 billion in funding for NASA — the first such authorization bill for the space agency in seven years. The bill more or less aligns with the budget blueprint Trump laid out last week. NASA won’t face the same cuts as other science […]
  • Designer Yeast Genome Key to Creating Complex Synthetic LifeDesigner Yeast Genome Key to Creating Complex Synthetic Life
    RepublishReprint LONDON (Reuters) – Scientists have taken a big step toward designing complex forms of life from scratch by constructing five new artificial chromosomes of baker’s yeast, representing a third of the micro-organism’s genome, or genetic blueprint. The international team used computers to create laboratory-made versions of the threadlike structures that carry genetic code inside […]
  • World’s Only Metallic Hydrogen Sample Has DisappearedWorld’s Only Metallic Hydrogen Sample Has Disappeared
    RepublishReprint Scientists achieved the “holy grail of high-pressure physics” last month, when physicists from Harvard University claimed they’d successfully turned hydrogen into a metal – something researchers had been struggling to achieve for more than 80 years. And not only had they made the material, but they were also the first to stably keep it […]
  • Dawn Discovers Evidence for Organic Material on CeresDawn Discovers Evidence for Organic Material on Ceres
    NASA’s Dawn mission has found evidence for organic material on Ceres, a dwarf planet and the largest body in the main asteroid belt between Mars and Jupiter. Scientists using the spacecraft’s visible and infrared mapping spectrometer (VIR) detected the material in and around a northern-hemisphere crater called Ernutet. Organic molecules are interesting to scientists because […]
  • ‘Extraordinary’ Pollution Found in Deep Mariana Trench‘Extraordinary’ Pollution Found in Deep Mariana Trench
    Highly toxic pollutants have been found in the world’s deepest sea trenches, a sign of the environmental damage wreaked by human activity on even the planet’s most remote habitats, according to new research. The results of surveys in the Mariana and Kermadec trenches, published in the latest edition of Nature Ecology & Evolution, highlight both […]
  • Martian Volcano Erupted for Two Billion Straight YearsMartian Volcano Erupted for Two Billion Straight Years
    Talk about hot stuff: A massive volcano on Mars erupted continuously for 2 billion years, a new scientific study reports. “For 2 billion years, there’s been sort of a steady plume of magma in one location on the surface of Mars,” study co-author Mark Caffee of Purdue University confirms in a statement. “We don’t have anything […]
  • Earth and Moon on Long-Term Collision CourseEarth and Moon on Long-Term Collision Course
    For now, our anomalously large Moon is spinning away from us at a variable rate of 3.8 centimeters per year. But, in fact, the Earth and Moon may be on a very long-term collision course — one that incredibly some 65 billion years from now, could result in a catastrophic lunar inspiral. “The final end-state […]
