Studies Spot Numerous Undiscovered Gene Alterations In Pancreatic and Brain Cancers NEW Sept. 05, 2008 HHMI investigators have detected a multitude of broken, missing, and overactive genes in pancreatic and brain tumors, in the most detailed genetic survey yet of any human tumor. Some of these genetic changes were previously unknown and could provide new leads for improved diagnosis and therapy for these devastating cancers. |

100-year study asks how forest management affects animals, plants NEW Sept. 04, 2008 A group of researchers led by Purdue University has begun to sample data for a planned 100-year study designed to develop better forest management methods and measure how such practices affect resident plant and animal species. "Our main goal is to find out how to most effectively regenerate oak and hickory forests, while examining the impact these treatments have on the whole ecosystem," said Cortney Mycroft, project manager for the study, called the "Hardwood Ecosystem Experiment." |

A Fine-Tooth Comb to Measure the Accelerating Universe NEW Sept. 05, 2008 Astronomers use instruments called spectrographs to spread the light from celestial objects into its component colors, or frequencies, in the same way water droplets create a rainbow from sunlight. They can then measure the velocities of stars, galaxies and quasars, search for planets around other stars, or study the expansion of the Universe. A spectrograph must be accurately calibrated so that the frequencies of light can be correctly measured. This is similar to how we need accurate rulers to measure lengths correctly. |

New Algorithm Significantly Boosts Routing Efficiency of Networks NEW Aug. 19, 2008 A time-and-money-saving question shared by commuters in their cars and networks sharing ever-changing Internet resources is: “What’s the best way to get from here to there?” A new algorithm developed by computer scientists from UC San Diego’s Jacobs School of Engineering helps answer that question, at least for computer networks; and it promises to significantly boost the efficiency of network routing. |

Molecular Evolution is Echoed in Bat Ears NEW Sept.04, 2008 Prestin codes for a protein of the outer hair cells – the tiny structures in the inner ear that help to give mammals their sensitive hearing. Important mutations occurred during the emergence of mammals that led to the evolution of Prestin from similar proteins. Since mammals evolved, it has been argued that the Prestin gene has changed little. |

Tracking Down the Menace in Mexico City Smog NEW Sept. 06, 2008 A new report by scientists who are part of the international MILAGRO Campaign indicates that some of the most harmful air pollution in imear090608_01_01 Mexico City may not come from motor vehicles but instead originates with industrial sources – and that the culprit may be garbage incineration. Beamline 11.0.2 at Berkeley Lab’s Advanced Light Source (ALS) was used for scanning transmission x-ray microscopy (STXM) of aerosol particles, in work led by Mary Gilles of the Lab’s Chemical Sciences Division. |

The Cassini Mission Tracking the Shepherd NEW Sept. 05, 2008 The Cassini spacecraft tracks the shepherd moon Prometheus as it orbits Saturn. This image is part of a sequence designed to monitor the evolution of a streamer of material in the F ring for nearly a full orbit, as it follows Prometheus. Here, Prometheus is just about to pass behind the planet. The faint streamer lies below and to the right of Prometheus (86 kilometers, or 53 miles across), in the faint, inner strand of the F ring. | |

Mars Missions Gallery Chloride Salt Deposits within a Channel in Terra Sirenum NEW Sept. 02, 2008 This image shows a series of knobs, channels and inverted channels in the ancient southern highlands of Mars. The inverted channels, which now appear as sinuous ridges, are filled with a fractured light-toned material that is also apparent in the knobs and nearby bedrock. Previous analyses of the infrared data from TES and THEMIS of similar materials in Terra Sirenum and elsewhere on Mars suggest that these light-toned materials are deposits of chloride salts such as sodium chloride (ordinary rock salt) | |

Integrated systems to perform orbital operations include electrical, command and data handling, flight control, and attitude and propulsion control. Components include rendezvous sensors, an autonomous fluid transfer unit and the robotic arm used to grapple the NextSat space craft and to transfer replacement batteries and electronics. |

Stellar Nights® Gallery Crescent Nebula (NGC6888) NEW Sept. 01, 2008 The Crescent Nebula, found in the constellation Cygnus, is estimated to be 5000 light years distant and 25 light years across. It was formed as a result of the central Wolf-Rayet star shedding it's outer layer combined with strong stellar wind. Shedding layers is an indication that the star is near the end of it's lifespan. The image was taken with a Meade LX200 10in SCT, F3.3 Focal Reducer, Meade DSI Pro II camera and a Hydrogen Alpha narrowband filter.By Paul Rix, PCW Memorial Observatory | |

The nebula is approximately 2400 Light years away and can be found in the constellation Cepheus. This false colour image was taken using a Meade LX200 10in SCT, F3.3 Focal reducer, Meade DSI Pro II camera and an Orion Ultra-Narrowband Hydrogen Alpha filter..

SOHO Pick of the Week A High Wind in the Heliosphere? NEW Sept. 08-15, 2008 An elongated coronal hole can be seen (diagonally across the Sun's center) in this September 3, 2008 image by SOHO. Coronal holes appear as darker areas when viewed in this extreme UV wavelength (195 Angstroms). Solar wind from coronal holes that are observed to the right of the Sun's central line connects best with Earth. Since coronal holes are 'open' magnetically, strong solar wind gusts, faster than other solar wind, escape from them and carry solar particles out to our magnetosphere and beyond. | |

Ike on September 4, 2008
NEW
Sept.
08 – 15, 2008 NASA's TRMM spacecraft observed this view of Hurricane Ike on September 4, 2008 as it strengthened in the Atlantic. At this time the storm was an extremely dangerous category 4 hurricane with sustained winds of 125 knots (143 mph) and a pressure reading of 935 millibars. Hurricane-force winds were extending outward 45 miles from the center, while tropical storm-force winds extend up to 140 miles. The cloud cover in this animation is taken by TRMM's Visible and Infrared Scanner(VIRS) and the GOES spacecraft. |

Where Have We Been NEW Aug. 12 2008 Many have of you have written and asked this question… So here is the answer. We have acquired a new sponsor. Whom at this time will not be announced for about two weeks. During discussion we all agreed that our current host was creating to many issues for us, including several down days a week, constant data errors in our galleries, and slow streaming abilities. The solution was discussed and a new host was acquired with a better server platform for our needs. We now have 1 million MB storage and unlimited bandwidth to work with. You will find that all sections within the site to perform well above the norm. |
