Site of asteroid impact changed the history of life

An asteroid, also known as the Chicxulub Impactor, hit Earth some 66 million years ago, causing a crater 180 km wide. The impact of the asteroid heated organic matter in rocks and ejected it into the atmosphere, forming soot in the stratosphere.
Soot is a strong, light-absorbing aerosol that caused global climate changes that triggered the mass extinction of dinosaurs, ammonites, and other animals, and led to the macroevolution of mammals and the appearance of humans.
Based on results of a new study, the researchers say that the probability of the mass-extinction occurring was only 13 percent. This is because the catastrophic chain of events could only have occurred if the asteroid had hit the hydrocarbon-rich areas occupying approximately 13 percent of Earth's surface.
Led by Tohoku University Professor Kunio Kaiho, the researchers came by their hypothesis by calculating the amount of soot in the stratosphere and estimating climate changes caused by soot using a global climate m…

       If one wanted to show just how much of a difference there is between a Marvel release and any other franchise release in terms of box office potential, this week would offer a textbook study. Thor: Ragnarok, the third and by many measures the best Thor movie to be released, is currently sitting comfortably at the top of t…

Breakthrough Junior Challenge : A Science competition - Here are the Finalist

Click Here for the list of winners of here>>

CHALLENGE :You get it. You’ve grasped an important scientific theory, concept or principle.

Now can you share your insight?

An inventive video can get across complex material that would take pages of text to communicate.

To take part in the Breakthrough Junior Challenge, create a short video (3 minutes max) to explain a big idea in one of these fields:PhysicsMathematicsLife SciencesYour film can take any form you like: animation, talking head, documentary, dramatic reconstruction, whatever. It’s worth keeping in mind that video is a dynamic visual medium – using diagrams, simulations, physical demonstrations etc. is a lot more effective than standing in front of a blackboard talking.

The videos will be judged according to the following criteria:
