• France's Top Wines Face Climate 'Tipping Point'

  Climate change has pushed French wines into uncharted territory, and could force producers to relocate, or abandon the grapes that helped to make their vineyards famous, scientists said Monday. Since 1980, growing conditions in northern climes such as Champagne and Burgundy, as well as in sun-drenched Bordeaux, have fundamentally changed the “harvest equation” that defined these storied regions, they reported in NatureClimate Change. “For much of France, local climates have been relatively stab..

• First Supernova Shock Wave Image Snapped by Planet-Hunting Telescope

  

  For the first time, scientists have seen the shock wave emanating from an exploding star in visible light. Using NASA's planet-hunting Kepler Space Telescope, researchers saw the shock wave coming from a massive star explosion (a supernova) that came into Kepler's view in 2011. The star that ended its life as a supernova is named KSN 2011d, which is nearly 500 times the diameter of the sun, and located about 1.2 billion light-years away. The shock breakout lasted only about 20 minute..

• This little flea -- and its huge appetite -- could ruin the Great Lakes

  

  It's just a flea, no bigger than a speck. But it eats like a hog. That's a problem because what the invasive spiny water flea from Europe and Asia likes to eat most is one of the coolest and most beneficial life forms in the food chain of Lake Mendota, the Daphnia flea. It grazes on algae, and the more it eats, the better the lake's water quality and visibility, making recreational pastimes such as swimming and fishing more pleasurable.  Since their arrival in cargo ships that sucked up fresh w..
