Submission + - U.S. Nuclear Weapons Compromised by UFO (reuters.com)

Arvisp writes: Witness testimony from more than 120 former or retired military personnel points to an ongoing and alarming intervention by unidentified aerial objects at nuclear weapons sites, as recently as 2003. In some cases, several nuclear missiles simultaneously and inexplicably malfunctioned while a disc-shaped object silently hovered nearby. Six former U.S. Air Force officers and one former enlisted man will break their silence about these events at the National Press Club and urge the government to publicly confirm their reality.

Submission + - Galactic Supervolcano Erupts From Black Hole (wired.com)

Arvisp writes: Volcanic eruptions can wreak as much havoc in space as on Earth, a new image of galaxy M87 reveals. The black hole at the galaxy’s center is spewing gas and energetic particles in what researchers call a “galactic supervolcano,” and suppressing the formation of hundreds of millions of new stars.
The new photo shows clouds of gas that glow in X-ray light (blue) surrounding the galaxy from observations taken by the Chandra X-ray Observatory, and jets of radio emission (red) from observations from the Very Large Array of radio telescopes in New Mexico.

This is all disputable. There are more than 5 places that claim to be centre of Europe. The strongest candidate being in Lithuania :D After a re-estimation of the boundaries of the continent of Europe in 1989, Jean-George Affholder, a scientist at the Institut Géographique National (French National Geographic Institute) determined that the Geographic Centre of Europe is located at 5454N 2519E.[2] The method used for calculating this point was that of the centre of gravity of the geometrical figure of Europe. This point is located in Lithuania, specifically 26 kilometres (16 miles) north of its capital city, Vilnius. http://en.wikipedia.org/wiki/Center_of_europe#Lithuania

Submission + - Hurricane formation linked to sea color (google.com)

Arvisp writes: A change in the color of the ocean could dramatically impact the number and intensity of hurricanes, according to US researchers. The main factor is the green tint ocean water takes when there are large concentrations of chlorophyll, a pigment that helps tiny organisms known as phytoplankton convert sunlight into food for the rest of the marine ecosystem.
Without chlorophyll, sunlight penetrates deeper into the ocean, leaving the surface water cooler.
Cold water in turn causes changes in air circulation patterns, forcing strong winds aloft, "which tend to prevent thunderstorms from developing the necessary superstructure that allows them to grow into hurricanes," the researchers said.

Submission + - First 3-D Porn Movie and it's from Hong Kong (tekgoblin.com)

tekgoblin writes: Christopher Sun of Hong Kong is directing a new porn movie that will actually be in 3-D. The movie is being called “3-D Sex & Zen: Extreme Ecstasy” and will be the first 3-D IMAX porn movie.

Submission + - Sun's 'quiet period' explained (bbc.co.uk)

Arvisp writes: Solar physicists may have discovered why the Sun recently experienced a prolonged period of weak activity.
The most recent so-called "solar minimum" occurred in December 2008.
Its drawn-out nature extended the total length of the last solar cycle — the repeating cycle of the Sun's activity — to 12.6 years, making it the longest in almost 200 years. The new research suggests that the longer-than-expected period of weak activity may have been linked to changes in the way a hot soup of charged particles called plasma circulated in the Sun.

Submission + - New process doubles efficiency of solar cells (nature.com)

Arvisp writes: Engineers at Stanford have developed a process which can harness the light and heat of the sun simultaneously, which could lead to solar cells that are twice as efficient as those currently available. Called photon enhanced thermionic emission — or PETE for short — the process differs from traditional cells which lose efficiency as temperatures rise, and the materials needed to build the cells are cheap and widely available. The engineers got around the lower efficiencies by coating a piece of semiconducting material with a thin layer of the metal cesium, which enables the material to use both heat and light simultaneously. While the materials as currently demonstrated work best in very high temperatures, the researchers indicate that in the near future, the materials could have wide enough application to make them competitive with traditional forms of energy.

Submission + - Car run on human waste is launched (telegraph.co.uk)

Arvisp writes: Excrement flushed down the lavatories of just 70 homes is enough to power the car for 10,000 miles — the equivalent of one average motoring year.
This conversion technology has been used in the past but the Bio-Bug is Britain's first car to run on methane gas without its performance being reduced.
It can power a conventional two litre VW Beetle convertible to 114mph.

Submission + - Apple, AT&T sued over iPhone 4 Attennas (appleinsider.com) 1

bannable writes: Apple has been accused of violation of the Federal Communications Act, three counts of products liability related to negligence, defect in design and breach of implied warranty, intentional and negligent misrepresentation, fraud by concealment, unfair business practices and more.

"The iPhone 4 manifests design and manufacturing defects that were known to Defendants before it was released which were not disclosed to consumers, namely, a connection problem caused by the iPhone 4's antenna configuration that makes it difficult or impossible to maintain a connection to AT&T's network," the California complaint reads.

Submission + - 'Sea monster' fossil found in Peru desert (cnn.com)

Arvisp writes: Researchers scanning the Peruvian desert for whale fossils have stumbled upon the remains of a "sea monster" three times the size of a modern day killer whale.
The teeth of "Leviathan Melvillei" were so large it was initially assumed they were elephant tusks.
"There were no elephants in South America before 3 million years ago, and the specimens found have an age of 12 to 15 million years, so that was impossible," said Professor Jelle Reumer, one of the team of scientists who found the fossil in the Pisco-Ica desert in coastal Peru.

Submission + - LHC smashes beam collision record (bbc.co.uk) 2

siloko writes: The world's highest-energy particle accelerator has produced a record-breaking particle collision rate — about double the previous record. The collider is now generating around 10,000 particle collisions per second, according to physicist Andrei Golutvin. Ramping up the funding rhetoric Mike Lamont told BBC News "It's clear that the LHC is the new boy in town, but in two years running we're going to put Fermilab out of business". As a neutral all I can say is the more collisions the better!

Submission + - Spitzer telescope pictures star being born (telegraph.co.uk)

Arvisp writes: Astronomers at the American Ivy League universities discovered the youngest known star in the Perseus star-forming region, about 800 light-years or more than 4700 trillion miles away from the Milky Way. Despite its tiny size, scientists believe they caught the precise moment the star, called L1448-IRS2E, was formed born. It is the most detailed glimpse of a star’s birth to date.
They took an extraordinary image of it using Nasa’s Spitzer Space Telescope. It has “just begun pulling in matter from a surrounding envelope of gas and dust” and only detected the faint light after it was emitted by the dust surrounding it.

Submission + - Ballmer announces new mobile OS from Microsoft (theregister.co.uk)

Arvisp writes: Microsoft has added yet another mobile operating system to its OS smörgåsbord: Windows Embedded Handheld, to be released sometime in the next six months.

Designed for what Redmond defines as the "enterprise handheld device market", Windows Embedded Handheld — which, for convenience, we'll shorten to WiEmHa, pronounced "weem-hah" — was announced by Microsoft headman Steve Ballmer in conjunction with Motorola's Thursday launch of its ES400 Enterprise Digital Assistant (EDA), a handheld that Moto marketeer Sheldon Safir touted for "the capability it has for moving workers from merely informed to truly empowered."
