As a little diversion this summer, we at Discovery Corps decided to see if we could predict the finalists on 'Dancing with the Stars' even before the contestants take to the dance floor. Data analytics professionals know that statistics can be fun, so we dove into it. We got some really interesting results. Have a look at the article on our website.

Yet most advertisers and publishers ignore clicks occurring after day #3. Not only 20% of all clicks occurred after day #3, but the best clicks (in terms of conversions) occurred several weeks after the email…

Hackers have proved they can crack just about any computer network, from Sony's to Citigroup's. Afterward, they face another challenge: unloading the virtual booty.
They often take stolen credit card numbers, online banking credentials, e-mail logins, and Social Security numbers to a sprawling network of underground chat rooms and invitation-only forums, where such data are bought and sold. Law enforcement investigators hoping to catch the crooks lurk there as well, but with hacking…

ROME (AP) – Seven scientists and other experts have gone on trial on manslaughter charges for allegedly failing to sufficiently warn residents before a devastating 2009 earthquake that killed more than 300 people in central Italy.
The case is being closely watched by seismologists around the globe who insist it's impossible to predict earthquakes and dangerous to suggest otherwise, since seismologists will be discouraged from issuing any advice at all if they fear…

Before I quench your curiosity to know more, let me for the benefit of everyone state here the three Laws of Motion as discovered by Sir Isaac Newton.

I am a Ph.D in chemistry and specialist in validated bioanalytical methods and also an amateur in database analytics.
