Scientists explain nitrogen-rich atmosphere of Earth with plate tectonics

Earth, unlike its neighbor planets Venus and Mars, has 78% nitrogen in its atmosphere. Our current day atmosphere is a result of billions of years of photosynthesis by plants, but that only increased the amount of oxygen to almost 20% of atmosphere, but why there is too much nitrogen in the atmosphere is still not understood well.

Now scientists try to explain abundance of nitrogen with plate tectonics. Plate tectonics is the reason for mountains and also volcanoes, when volcano erupts it does bring lot of deep earth stuffs into the surface of earth.

Gases like sulfur, carbon dioxide and nitrogen are the gases usually comes out of volcanic eruption.

Scientists say that nitrogen is locked into the silicate rocks in the earth’s crust. When this silicate rocks interact with oxygen based compounds, they break into water (H2O) and nitrogen (N2). This nitrogen then came out of volcanic eruption to the atmosphere.

This is why Mars and Venus have little nitrogen because they don’t have plate tectonics.

Germany Demands Google to Show Their Searching Algorithms

Heiko Mass, Germany’s justice minister, wants Google to open their searching algorithms so the way Google works will be much more transparent. Google has lot of impact on businesses lately, and depending on how businesses are shown in Google’s search results make a major impact in businesses.

With Google dominating online search market with more than 60%, Google has become a standard for online search, and many of Europe countries including Germany feels that Google take this as an advantage and promoting its own brand of services over native services in Europe.

So Germany’s minister believes that Google must expose how it’s searching algorithms works, therefore explaining the search results with high Google service dominance.

Even though Google’s many works are open source, including all famous Android OS, but very important aspects of Google’s primary income generating businesses are closed source and proprietary. Google Search is one of these deeply closed and guarded project. Showing the algorithm to authorities may ended up in technology breach and others copying the algorithms.

Microsoft’s EMET 5.0 is Released, Providing Extensive Defense Against Cyber-Attacks

Enhanced Mitigation Experience Toolkit is Microsoft’s second layer of security that was primarily available for enterprise customers, it helps prevent damages against cyber-attacks, and providing methods to detect and block exploitations techniques that are used by cyber criminals. It provides real time protection against such attacks and help secure your system before your formal anti-virus or anti-malware get updates with the patch for such attacks.

EMET is less known by normal users, because it wasn’t much advertised by Microsoft, but now this EMET is free and anyone can use it, even on your home computers, and it gives you extra protection against hackers.

EMET is also compatible with most anti-virus and anti-malware applications, so it can work alongside to provide more security.

Download EMET 5.0 here (11MB)

Material Design Comes to Google Chrome Beta for Android

Google revealed Android 5 in their IO conference, it is called Android L, and it has some new UI makeovers, that Google called it Material Design. It gives more attention to type and have lot of animation based UI changes.

Before releasing the actual OS, Google has already showed off few of their apps with Material Design such as Gmail and Maps. Now Google released Chrome Beta for Android with Material Design.

Chrome Beta 37 has totally new look, but the dev team said they were experimenting with some of the elements of Material Design. It seems they will continue to work with the new design and finally it will come to Chrome for Android.

Three Super Massive Black Holes Rotating Closely

4.3 billion light years away, in a distance galaxy, 2 black holes have been identified, they are not ordinary black holes, they are supermassive black holes, that is they are millions or billions time massive than our Sun. Usually these kind of black holes lies in the center of the galaxy.

Super massive black holes are surrounded by disk of glowing hot gas, commonly with that it forms quasar. Quasars are monstrous objects in space and with its colossal power can outshine the entire galaxy.

The quasar named SDSS J1502+1115 is in constellation Bootes, 4.3 light years away is actually 2 supper massive black holes and are almost 24,000 light years apart. But when scientists looked one black hole closely with intercontinental array of radio dishes – which can produce sharper images than Hubble Space Telescope – they discovered that one of the black hole is actually a duo.

This new found pair of black holes are actually 450 light years apart and orbiting each other every 4 million years. There is only one more tightly paired black hole we ever discovered and that is 24 light years apart.

Scientists believe that tightly paired black holes can help detect “gravitational wave” predicted by general relativity, but so far no known binary black holes are tight enough to cause detectable gravitational wave.
