(Best Syndication News) - Researchers from UCLA predict that temperatures in the Los Angeles region will increase by an average 4 to 5 degrees by 2060. The downtown Los Angeles area is expected to triple the number of hot days. The valleys and high elevation areas are expected the quadruple the number of hot days.

The study is called “Mid-Century Warming in the Los Angeles Region.” The study was funded and supported by the city of Los Angeles and the Los Angeles Regional Collaborative for Climate Action and Sustainability (LARC) group. The LARC group is made up of leading municipal governments, agencies, universities, and other organizations.

Tundra’s Vegetation Changes attributed to Warmer Temperatures

“We’ve managed to show that the vegetation changes in our fixed plots are a result of local warming at numerous sites across the world’s tundra,” Robert Björk says.

(Best Syndication News) - The recent years have been warmer for the Arctic Tundra Region, which has Scientist noticing more green coverage and taller plants in the area. Researchers from the University of Gothenburg, Sweden published their study results in the Nature Climate Change and Ecology Letters journal.

The researchers found that most plants have grown taller in the Arctic. The bare ground areas have lessened. There also has been an increase in the number of evergreen shrubs growing.

For almost 30 years, researchers have been collecting data on with the International Tundra Experiment (ITEX). The researchers on this study investigated Arctic vegetation changes in 158 plant communities at 46 locations between 1980 and 2010.

Arc of Venus to Appear Tuesday and Wednesday

(Best Syndication News) Astronomers will be watching the planet Venus on June 5th and 6th as it travels between the sun and the earth. They hope to learn more about the planet by studying the Arc of Venus, a phenomena seen in 2004 as the sun’s rays passed through the atmosphere of the planet.

Astronomers in 1639 used the transit of Venus across the sun to estimate the size of the solar system. On Tuesday they hope to discover the secret to the planet’s super-rotation. While the planet’s spin takes 243 earth days, the atmosphere circumnavigates the planet in just four days.

FAA grants Scaled Composites permit to Launch Suborbital SpaceShipTwo and WhiteKnightTwo

(Best Syndication News) - Virgin Galactic announced that their vehicle developer, Scaled Composites (Scaled), was given the OK by the Federal Aviation Administration (FAA) to launch a suborbital spacecraft named SpaceShipTwo and the carrier aircraft named WhiteKnightTwo. Virgin Galactic is the world’s first commercial spaceline that has the goal of taking private travelers into space.

"This important milestone enables our team to progress to the rocket-powered phase of test flight, bringing us a major step closer to bringing our customers to space," said George Whitesides, president and CEO of Virgin Galactic. "We thank the FAA for their timely issuance of this permit, and for their responsible oversight of the test program."

Astronomers Examine one of the Largest Clusters in Universe

Large Galaxie Supercluster

(Best Syndication News) Astrophysicists from the McGill University in Quebec, Canada, have discovered two giant galaxy clusters which appear to be colliding connected by a filament of stars . When combined, this supercluster of galaxies could be one of the largest structures in the universe.

Using the Herschel Space Observatory and its single 3.5 meter mirror telescope in space, scientists are peering back in time to see two clusters of galaxies crash together. The McGill team hopes to shed light on how galaxies and clusters of galaxies evolve.

There is a nature vs nurture debate among astronomers. Some believe that the evolution of galaxies is determined by intrinsic properties like the total mass. Others believe there is more to it, and wider-scale cosmic environmental forces will dominate the progression of galaxies.
