RotM: Interview with Dr. Steven Churchill

Prof. Steven E. Churchill In continuation of our newly introduced, Researcher of the Month (RotM) series, we spoke to Professor Steven Churchill , professor of Evolutionary Anthropology at Duke University .  Prof. Churchill specializes in human paleontology and his research interests include studying archaic and modern humans of the Middle and Late Pleistocene era.  In his recently published paper in Current Anthropology , Prof. Churchill and his team discuss the 'feminization' of human skull and origins of the life that we live today.  Here's Prof. Churchill, telling us more about his findings.  CTS: For the benefit of our readers, please tell us about the fresh perspective that your recent findings have provided on the origins of Behavioral modernity?         SC : Humans are remarkably socially tolerant compared to most other animals.  We often gather with strangers in large numbers without violence (something that would not happen with chimpa

Do free energy magnetic motors really work?

The internet is rife with websites that promote generators that are capable of providing electricity without using any fuel. Built largely with magnets, these 'free energy generators' promise to cut your electricity bills and provide a much greener alternative to the electricity that is largely generated out of fossil fuels. Elaborate videos that give you estimates of how much money you can save without revealing any details of how to go about it, manage to keep the audience hooked on for a while, but $40 price tag, the loads of freebies and the instant $10 discount for not leaving the page, make the product and its seller highly suspicious. So, we decided to find out if these free energy magnetic motors really work? The Principle The magnetic motor works on the simple principle that we all already know, 'Like poles repel each other while opposite poles attract each other'. By arranging the magnets in a fashion where only like poles face each other, one c

7 Billion: How Did We Get So Big So Fast?

We always speak of population booming around the globe and the consequences that we will face in the near future due to our explosive rate of growth that our species has seen. Here's a short explanation of how did we get so big so fast! For those who would like to use this information with a little bit of historical context, here is a great video from American Museum of Natural History's YouTube channel that gives you a little insight into evolution, the famous Empires of the world, the stages of human progress and a few tips to prepare for a better future. If you like these video, do share them with your friends, family and colleagues.

5 reasons that make Rosetta a SUPERSTAR!

Artist's rendition of Rosetta approaching comet 67P Image Source: ESA For the next few days (and probably many many years), you are likely to come across people speak of the greatness of 'Rosetta' and about her achievements and before you start thinking that the Rosetta is some entrepreneur, social worker, sportswoman or the worst, a movie star, let us make it very clear that Rosetta is actually a spacecraft. and still a Superstar! Here are 5 things that have make Rosetta famous! Rosetta, is a spacecraft built by the European Space Agency , at a cost of 1.3 billion Euros, with the aim to study the comet 67P/ Churyumov- Gerasimenko. Discovered in 1969, the comet orbits around our Sun every 6.6 years and Rosetta's mission to understand what this comet is made up. The mission will give us scientists further information on how our Solar System originated and evolved, since our Sun, planets and all the comets are made up of the same pre-solar nebula that existed ov
