Revolutionary Theory of Dark Matter |

The universe abounds with dark matter. Nobody knows what it consists of. University of Oslo physicists have now come up with a mathematical explanation that could solve the mystery once and for all.

Astrophysicists have known for the last 80 years that most of the universe consists of an unknown, dark matter. The solution to the mystery may now be just around the corner.

“We are looking for a new member of our particle zoo in order to explain dark matter. We know that it is a very exotic beast. And we have found a plausible explanation,” reports Are Raklev, an associate professor in particle physics in the University of Oslo’s Department of Physics to the research magazine Apollon.  He is the university’s leading theorist in astroparticle physics and has launched a model that explains what dark matter may consist of and how one can discover the invisible particles experimentally.

Even though dark matter is invisible, astrophysicists know it exists. Without this dark matter it is impossible to explain how the visible things in the universe hang together. continue reading

Multicolored Sun |

The sun is more than meets the eye, and researchers should know. They’ve equipped telescopes on Earth and in space with instruments that view the sun in at least ten different wavelengths of light, some of which are represented in this collage compiled by NASA and released January 22. (See more pictures of the sun.)

By viewing the different wavelengths of light given off by the sun, researchers can monitor its surface and atmosphere, picking up on activity that can create space weather.

If directed towards Earth, that weather can disrupt satellite communications and electronics—and result in spectacular auroras. (Read an article on solar storms in National Geographic magazine.)

The surface of the sun contains material at about 10,000°F (5,700°C), which gives off yellow-green light. Atoms at 11 million°F (6.3 million°C) gives off ultraviolet light, which scientists use to observe solar flares in the sun’s corona. There are even instruments that image wavelengths of light highlighting the sun’s magnetic field lines.

With its generative patterns and unique interface, Deko, which was first highlighted by Creative Applications, deviates sharply from your standard wallpaper app, falling into an experimental category. Upon first launch, the app guides you through its navigation and features: swipe to the left to generate a new pattern; swipe right to view a previous pattern; then tap to save, export or share your results. After generating a background, you can opt to generate similar patterns by swiping various distances from right to left. (via A wallpaper app that wont put you to sleep: Deko for iOS lets you generate patterns on the fly - The Next Web)

A light microscope image of a purple sea urchin (Strongylocentrotus purpuratus) egg after fertilization is shown here. The outer circle area is called the vitellien layer. Purple sea urchins may be found on rocky bottoms and grazing intertidal and subtidal waters. They feed primarily on algae and brown kelp.

Feds Dismantle Piracy Ring That Stole Super-Expensive Software

infoneer-pulse:

A Chinese national was set to plead guilty Monday for his role in a massive $100 million online software piracy scheme that authorities said was “one of the most significant copyright infringement cases ever uncovered.”

According to Delaware federal court papers, Xiang Li has agreed to plead guilty to two federal charges related to the selling, without authorization, of high-end software programs for a fraction of their retail worth.

Getting your privacy back is like getting your virginity back,” said Jim Reavis, Executive Director of the non-profit Cloud Security Alliance, from a room on the second floor of Las Vegas Convention Center North building. The on-stage conversation between Reavis and other privacy experts focused mainly on desired changes to how to make the nebulous concept of online privacy more user-friendly.
Sid Stamm, lead privacy engineer for Mozilla, suggested that just because more and more data is being hosted remotely, “in the cloud,” that doesn’t mean that it’s automatically less safe. “If we introduce transparency, we can make people feel safer about where their data is being stored,” he said.
He also said that he thought that developers have to start matching data and privacy management to user expectation. “We should be engineering products which only do what [end-users] expect them to do. It may be harder, but it’s in our best interests,” he said.
