[QUOTE]The findings come after scientists studied small fragments of the Chelyabinsk meteor that made it through the massive explosion in Earth's atmosphere and landed on the ground. Lead researcher Shin Ozawa, of Japan's University of Tohoku, and his team found a rare mineral called jadeite in glass-like veins inside the samples. That mineral could only be produced under massive pressure and heat, such as that from an impact with another asteroid. By studying the shape and structure of the jadeite crystals, they were able to estimate the size, temperature, and duration of the impact. The results were published this week in Scientific Reports. Previously, scientists had used video footage to determine the path of the meteor to Earth, and analysis of the impact found it to be the second largest explosion in recorded history.[/QUOTE]

[QUOTE] If astronomers are right, all life on this planet could be extinguished in less than 30 years from now. Scientists at NASA's Jet Propulsion Laboratory have detected a large object the size of Manhattan possibly on a collision course with Earth. Using their Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE), the 10-mile wide object was found approximately 51 million miles from Earth. Scientists believe that during a close encounter with Mars, the asteroid was nudged slightly off its usual orbit and may currently be on a high speed collision course with our fragile planet.

The asteroid is calculated to have a potentially lethal encounter with the Earth on March 35, 2041. Astronomers have placed the odds of an impact at 1 in 2.04, which is by far the most unprecedented risk ever faced to humanity, let alone from asteroids. Such an impact could potentially end civilization as we know it.

More information will be posted here as the story develops.[/QUOTE]

edit: oops I now see it's not vetted by CNN yet.

God doesn't exist, so she can't have done it.

For proof I refer the reader to various publications of Dawkins, R.

New wind turbine design
 

[url]http://www.gizmag.com/the-archimedes-liam-f1-urban-wind-turbine/32263/[/url]

[QUOTE]Although it's getting increasingly common to see solar panels on the roofs of homes, [URL="http://www.gizmag.com/secret-energy-wind-turbine/14299/"]household wind turbines[/URL] are still a fairly rare sight. If Rotterdam-based tech firm The Archimedes has its way, however, that will soon change. Today the company officially introduced its Liam F1 Urban Wind Turbine, which is said to have an energy yield that is "80 percent of the maximum that is theoretically feasible." That's quite the assertion, given that most conventional wind turbines average around 25 to 50 percent.
The 75-kg (165-lb) 1.5-meter (5-ft)-wide Liam obviously doesn't look much like a typical turbine. It draws on the form of the nautilus shell, and the screw pump invented by ancient Greek mathematician Archimedes of Syracuse.
That form factor reportedly results in minimal mechanical resistance, allowing it to spin very freely [I]and[/I] to operate quietly – blade noise is one of the common complaints regarding rooftop wind turbines. Additionally, the design is claimed to keep it always pointing into the wind for maximum yield.

Gamma ray burster in M31.
 

A gamma-ray burster went off right next door a few hours ago. It appears to have been in the globular cluster FMZ2005-7 which is part of the Andromeda spiral galaxy.

Twitter is full of it under the hashtag #GRBm31, from where I found many more details at [url]https://www.facebook.com/bob.rutledge/posts/10154206617205249[/url]

Relatively low energy compared with the big boys (only 1e-10 of brightest known) so probably collision between two neutron stars or the energy was very strongly beamed in our direction.

What a pity we don't have any operating gravity wave detectors of sufficient sensitivity right now
