Weaving electronics into the fabric of our physical world NEW Jan. 24, 2012 The potential applications for nanophotonics and nanoelectronics are truly startling, suggesting the brink of a revolution in human–machine interfaces that could turn science fiction into a reality. |

Study shows restored wetlands rarely equal condition of original wetlands NEW Jan. 25, 2012 Wetland restoration is a billion-dollar-a-year industry in the United States that aims to create ecosystems similar to those that disappeared over the past century. But a new analysis of restoration projects shows that restored wetlands seldom reach the quality of a natural wetland. |

Distant
star-forming galaxies in the early Universe
NEW
Jan.
25, 2012 Astronomers have combined observations from the LABOCA camera on the ESO-operated 12-meter Atacama Pathfinder Experiment (APEX) telescope with measurements made with ESO’s Very Large Telescope, NASA's Spitzer Space Telescope, and others, to look at the way that bright, distant galaxies are gathered together in groups or clusters. |

Absorbing
Hydrogen Fluoride Gas to Enhance Crystal Growth
Dec. 10, 2009 Two scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have developed a method to control the buildup of hydrogen fluoride gas during the growth of precision crystals needed for applications such as superconductors, optical devices, and microelectronics. The invention — by Vyacheslav Solovyov and Harold Wiesmann and recently awarded U.S. Patent number 7,622,426 — could lead to more efficient production and improved performance of these materials. |

Researchers Discover 'Green' Pesticide Effective Against Citrus Pests NEW Jan. 20, 2012 University of Florida researchers have discovered a key amino acid essential for human nutrition is also an effective insecticide against caterpillars that threaten the citrus industry. The Lime Swallowtail, or Citrus Swallowtail, is a well-known agricultural pest from southern Asia discovered in the Caribbean in 2006, and researchers say its potential impact on the U.S. citrus industry is cause for serious concern. |

Biodiversity Loss Costs EU 450 Billion Euros Per Year NEW Jan. 25, 2012 In addition to the financial crisis, there is a silent crisis of biodiversity loss costing the EU 450 billion Euros each year. ALDE MEP Gerben-Jan Gerbrandy (D66, Netherlands), Special Rapporteur on Biodiversity of the European Parliament, presented his draft report on January 24 to the environment committee and called for the "No Net Loss" principle to be applied - that those who cause damage to nature must compensate the loss. The European Parliament intends to come forward with a strategy to end biodiversity loss by 2020. (runtime 03:23) |

Injecting sulfate particles into stratosphere won’t fully offset climate change NEW Jan. 25, 2012 As the reality and the impact of climate warming have become clearer in the last decade, researchers have looked for possible engineering solutions – such as removing carbon dioxide from the atmosphere or directing the sun’s heat away from Earth – to help offset rising temperatures. New University of Washington research demonstrates that one suggested method, injecting sulfate particles into the stratosphere, would likely achieve only part of the desired effect, and could carry serious, if unintended, consequences |

Dune
Patterns
NEW
Jan. 23,
2012 Data from NASA's Cassini spacecraft show that the sizes and patterns of dunes on Saturn's moon Titan vary as a function of altitude and latitude. The dunes in areas that are more elevated or are higher in latitude, such as in the Fensal region pictured at bottom left, tend to be thinner and more widely separated, with gaps that have a thinner covering of sand. Dunes in the Belet region, pictured at top left, are at a lower altitude and latitude. |

Jan.
26, 2012 Here we see three views of an image collected during MESSENGER's first flyby of Mercury in January 2008. The top two images have had a harsh contrast stretch applied, to emphasize portions of the image with low signal levels. Notice that in the top left image there are bright streaks in the sky that extend from the edge of the planet toward the bottom of the image. |

Mars Missions Gallery Dune Composition NEW Jan. 25, 2012 Sand dunes are among the most widespread aeolian (wind-formed) features present on Mars. Their spatial distribution and morphology are affected by changes in wind direction and wind strength. Patterns of dune erosion and deposition provide insight into the sedimentary history of the surrounding terrain. | |

The
Helix Nebula
Jan. 19, 2012 The Helix Nebula is one of the closest and most remarkable examples of a planetary nebula. It lies in the constellation of Aquarius (The Water Bearer), about 700 light-years away from Earth. This strange object formed when a star like the Sun was in the final stages of its life. Unable to hold onto its outer layers, the star slowly shed shells of gas that became the nebula. It is evolving to become a white dwarf star and appears as the tiny blue dot seen at the center of the image. |

Impact
Crater
Jan. 19, 2012 This image covers a "fresh-looking" impact crater with a diameter of about 2 kilometers (1.2 miles). There are gullies all around the steep inner slopes of this crater (you can even see them in the shadow by enhancing the brightness of this region), at 35 degrees South latitude. Many craters at this latitude in the Southern hemisphere only have gullies on the south-facing slopes, which are shadowed in the wintertime. But this is an especially pristine crater so the slopes may be particularly steep and unstable. |

Jan. 16, 2012 CERN, the European Organization for Nuclear Research, is one of the world’s largest and most respected centers for scientific research. We conduct fundamental research in physics to study the basic constituents of matter-- the elementary particles. By studying what happens when very energetic particles collide, physicists can learn more about the laws of nature. |

The
Solar Cycle
Jan. 13, 2012 The number of sunspots increases and decreases over time in a regular, approximately 11-year cycle, called the sunspot cycle. The exact length of the cycle can vary. It has been as short as eight years and as long as fourteen, but the number of sunspots always increases over time, and then returns to low again. |

A Guide to Solar Flares
Jan. 11, 2012 Flares happen when the powerful magnetic fields in and around the sun reconnect. They're usually associated with active regions, often seen as sun spots, where the magnetic fields are strongest. Flares are classified according to their strength. The smallest ones are B-class, followed by C, M and X, the largest. |
