We summarize the week's scientific breakthroughs every Thursday.
- 			 Earth EarthSaltier Water: Climate change can slow ocean’s absorption of carbon dioxide gasA decrease in precipitation over the Pacific Ocean north of Hawaii in recent years has left the ocean there saltier and has diminished its ability to soak up carbon dioxide. By Sid Perkins
- 			 Agriculture AgricultureFluid Security—Overcoming Water Shortfalls in the 21st CenturyAbout 70 percent of Earth’s surface is covered with water, some 1.4 billion cubic kilometers of it. Too bad almost 96.5 percent of it’s salty, and another 2 percent is locked away as ice in remote places such as Greenland and Antarctica. All told, just a little more than 1 percent of our planet’s water […] By Sid Perkins
- 			 Earth EarthBt corn pollen can hurt monarchsA second test of a strain of corn genetically engineered to make its own insecticide finds potential for harm to monarch butterfly caterpillars. By Susan Milius
- 			 Earth EarthHigh-Flying Science, with Strings AttachedIn the hands of scientists, kites do serious data gathering. By Sid Perkins
- 			 Earth EarthSmall quake shakes up hydrothermal ventsLong-term, post-earthquake fluctuations in the temperature and volume of water spewing from hydrothermal vents off the coast of Washington state suggest that the fluid flow feeding such vents may be much more complex than previously thought. By Sid Perkins
- 			 Earth EarthLarge lake floods scoured New ZealandA volcanic region of New Zealand’s North Island experienced immense floods and severe erosion when lakes filling the craters of dormant volcanoes burst through the craters' rims and poured down the slopes. By Sid Perkins
- 			 Earth EarthFor European lakes, how clean is clean enough?New research on lakes in Denmark suggests that agriculture has been affecting water quality there for more than 5,000 years. By Sid Perkins
- 			 Earth EarthExtracting Estrogens: Modern treatment plants strip hormone from sewageNew research helps explain why state-of-the-art sewage treatment facilities are more effective than conventional plants at removing certain sex hormones from sludge. By Ben Harder
- 			 Agriculture AgricultureLocal Foods Could Make for Greener GrocersThere was a time not so long ago when people tended to select the ingredients for their meals either from what was available that week at local markets or from out-of-season home-canned, -smoked, or -pickled goods in the family larder. No longer. Maryland cooks can pick up New Zealand lamb or Icelandic salmon any time […] By Janet Raloff
- 			 Earth EarthAir SicknessStudies have begun showing subtle but substantial harmful effects in outwardly healthy people who regularly breathe hazy air. By Janet Raloff
- 			 Earth EarthLong-Term Ocean Venting: Seafloor system has been active for agesAnalyses of mineral deposits in and around a unique set of hydrothermal vents beneath the Atlantic Ocean suggest that the site's tallest towers of minerals have been growing for at least 30,000 years. By Sid Perkins
- 			 Earth EarthCatch ZeroIt generally has taken less than a generation for modern, industrial-scale fishing, once deployed in a new plot of ocean, to exhaust the vast majority of the sea’s edible bounty and leave behind decimated ecosystems and depleted economic opportunities. By Ben Harder
