Weaving
electronics into the fabric of our physical world
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
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
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
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
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
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 |

The Cassini Mission
Dune
Patterns
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. |

The Messenger Mission
Smear
Campaign
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. |

Observatory Gallery Arp 116 NEW Sept. 06, 2012 This video shows Hubble observations of Arp 116, a pair of galaxies in the constellation of Virgo. It is made up of M60, a large elliptical galaxy, and a smaller, bluer spiral galaxy, NGC 4647. It has long been unclear whether the two galaxies are actually interacting, or whether they simply appear close together from our distant vantage point. However, detailed studies of Hubble pictures suggest that the pair are beginning to experience tidal forces. | |

Observatory Gallery The globular star cluster Messier 4 NEW Sept. 05, 2012 The Milky Way galaxy is orbited by more than 150 globular star clusters that date back to the distant past of the Universe (eso1141). One of the closest to the Earth is the cluster Messier 4 (also known as NGC 6121) in the constellation of Scorpius (The Scorpion). This bright object can be easily seen in binoculars, close to the bright red star Antares, and a small amateur telescope can show some of its constituent stars. | |

Solar, Earth Atmospheric and Climate Gallery RBSP Science Overview NEW Sept. 05, 2012 The Radiation Belt Storm Probe mission (RBSP) will explore the Van Allen Radiation Belts in the Earth's magnetosphere. The charge particles in these regions can be hazardous to both spacecraft and astronauts. Project Scientist David Sibeck explains the how the mission will explore space weather -- changes in Earth's space environment caused by the sun -- that can disable satellites, create power grid failures and disrupt GPS service. | |

Solar, Earth Atmospheric and Climate Gallery GPM Applications NEW Sept. 04, 2012 Water is fundamental to life on Earth. Knowing where and how much rain and snow falls globally is vital to understanding how weather and climate impact both our environment and Earth’s water and energy cycles, including effects on agriculture, fresh water availability, and responses to natural disasters. Since rainfall and snowfall vary greatly from place to place and over time, satellites can provide more uniform observations of rain and snow around the globe than ground instruments, especially in areas where surface. . . | |

Solar, Earth Atmospheric and Climate Gallery Birth of a Space Laser Instrument NEW Sept. 04, 2012 A new C02 laser, which will globally measure carbon dioxide from space, is due to be launched in 2023 on the ASCENDS mission. One of the exciting things about this project is that you can actually watch trees eat and breathe. Of course, trees are breathing all the time, but they are only eating, meaning, performing photosynthesis when the sun is out. The main science is to measure how much carbon dioxide there is in the atmosphere at this particular time on the Earth, how much is there total and where is it located. | |

Solar, Earth Atmospheric and Climate Gallery The Ocean NEW Aug. 31, 2012 The Ocean is essential to life on Earth. Most of Earth’s water is stored in the ocean. Although 40 percent of Earth’s population lives within, or near coastal regions- the ocean impacts people everywhere. Without the ocean, our planet would be uninhabitable. This animation helps to convey the importance of Earth’s oceanic processes as one component of Earth’s interrelated systems |

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. |

X-Class:
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. |
