Harvesting dinosaurs from Ghost Ranch [Video]

Tyrannosaurus rex, Palais de la Découverte, Paris (Photo credit: Wikipedia ) Once in a while, we come across a news story of paleontologists finding a dinosaur fossil in some part of the world. The significance of the fossil is then explained and the news story is buried into the depths of our mind to be excavated out the next time, there is a similar news story. But there is a lot more than happens between discoveries, which is left out of the story but if you would like to witness it, you could simply visit, the Ghost Ranch in New Mexico , a hot bed for finding dinosaur fossils. In this episode of the Shelf Life, you can see how dinosaur fossils are excavated and prepared to be brought back to the American Natural History Museum to be added to their vast collection and studied some day. Excavations in Ghost Ranch began in the year 1928 and continue to this day.

This 56 year old woman is happy about having a brain stroke [Video]

Jill Bolte Taylor Image credit: Every four minutes a person dies in the United States of a stroke! Much like a heart attack, a stroke can happen at any time and to any body, irrespective of their age, sex or standard of living. Strokes occur when blood supply to the brain is affected. This might be due to a a block in the blood vessel or rupturing of the blood vessel, both of which, deprive the brain cells of essential nutrients and more importantly oxygen, and they die. When brain cells die, they take away with them some unique ability they were conferring before the event of the stroke. So, after a stroke, some people lose their control over some muscles, some may forget names, some lose their identity, while most become partially paralyzed. Any which way, stroke is a debilitating condition and usually worsens the quality of life of the person affected and no one can be happy about it.  Except, Jill Bolte Taylor! A neuroanatomist by profession, Dr.

What Did Evolution Get Wrong [Video]

About 6 days and 90 years ago, the Criminal Court of Tennessee sentenced a high school teacher, John Thomas Scopes , guilty of teaching human evolution in school. The Scopes Trial or the Scopes Monkey Trial , as it is famously known, was a big event for its time and set the tone for debate whether evolution should or should be taught in schools. While the debate continues even today and people continue to argue over the merits and demerits of the evolution theory , we came across this short video from BBC Earth Unplugged that actually questions the theory of evolution, in a fun way. Disclaimer: Neither the BBC Earth Unplugged nor Coffee Table Science are attempting to question the theory of evolution, it's just that these are interesting questions that need to be asked so enjoy the video. If you have liked video, do let us know your thoughts on it below. There are some interesting posts on our blog about the fast moving tiger beetles and extreme sex seen in animal

Coffee break in space [Coffee byte]

Taking a coffee break is as human as going to the toilet. which is probably why NASA has put together some of the most brilliant scientist to crack the code on how to enjoy a Cup-A-Joe in outer space.

Red Crab Marathon for Survival [Video]

Red Crab on Christmas Island, Australia. (Photo credit: Wikipedia ) If you believed humans have taken great risks when migrating to new places in search of food and water before, you have not seen the lives of many animals that migrate over long distances to ensure that the next generation gets the best environmental conditions to grow and survive and take the species forward. The migration of the Monarch Butterflies is quite well documented and you will find many videos online for them. But here is another story of the Red Crab that braves heights and ants to make it to the sea!

Discovering the Olinguito, in the museum [Video]

An Olinguito Photo courtesy:  The Olinguito was one of the Top Ten New Species of 2014 and is a mammal that is found in the misty mountains of Ecuador and Western Columbia. While this carnivorous mammal has been spotted multiple times before and even displayed in the zoos of the United States before, people mistook the creature for a common racoon.  However, olinguitos are tree-living animals and prefer to habitat stretches of mountains that are 5000-9000 feet high. They just have a single mammary gland and bear a single offspring at in a single gestation.  It actually took an accidental discovery in the museum to get the classification right! Here is the story of the Discovery of Olinguito by Kristofer Helgen and how specimens are maintained and analysed in the museum courtesy of the Shelf Life series from the American Natural History Museum 

The Science Behind Love [Video]

Photo credit: AMNH If you have ever marvelled at how a museum is curated, its collections maintained and who are the people who create the magic therein, then here is your chance to find out more about the happenings inside, sitting in the comfort of your home. The American Museum of Natural History at Central Park West , New York has recently started a video series called Shelf Life  on YouTube , which takes us behind the scenes of the popular museum. The first Episode premiered in November last year and is titled 33 Million Things, an approximate number of artifacts and specimens that the museum holds and gives a sneak preview of what we can expect from the year long series. From Zoological specimens to terra bytes of images of stars, galaxies and planets, frozen DNA and tissue samples and artifacts from Native North American culture, the series opens doors to thi

Salt and Water Waltz [Video]

If you have enjoyed watching the video above, then you are going to absolutely love the science behind it that makes it possible!  All this chemical dancing was made possible by a simple finding that we can move objects using sound waves . This requires no spells that you can learn only at the Hogwarts School of Wizardry, but just the simple application of acoustic levitation . Scientists have been able to levitate light objects using nothing but sound waves (at particular frequencies) from a speaker. But researchers Dimos Poulikakos and Daniele Foresti at the University ETH Zurich have modified this well known method that not only allows them to levitate objects but also move them to their hearts desire! The result, the salt and water waltz above.  This technique is known as acoustophoresis in the scientific world and can be applied in the pharmaceutical industry where one wishes to mix ingredients without contaminating them.  If you work in a lab that has

Science and Christmas [Video]

When it comes to Christmas and Santa Claus there are so many questions that we don't seem to have answers to. Being a skeptic can sometimes take the fun out of the whole festival.  Well the guys at AUT University (Aukland University of Technology) have tried to answer a few of those baffling questions, so that we (the skeptic) can lay back and enjoy the very things that make Christmas the greatest time of the year.

Nature by Numbers [Video]

For all those who hate mathematics, here is a a simple video showing us nature in numbers! Signature of God or the principle of nature, we do not really know and sometimes it is okay to not be the Know-it-alls.

Up Close with a Volcano [Video]

Volcanoes are of the most dreaded natural phenomenon ! The US Geological Survey estimates around 1500 active volcanoes in the world and this number does not include the volcanic activity occurring on ocean floors. But there is a lot that we still need to understand about the  volcanoes. But to study them, we need to get closer to them and this is where the problem arises. The temperatures near an active volcano exceed 1000 degrees Celsius with ease which demands for special apparatus to fight heat and survival. But a Shenzhen (China) based company has now shown that modern technology can help us reach places that we have never reached before without having to spend billions on development. All one needs to do is use existing technology smartly. Here,you can see how a $1000 quad-copter can bring you up close images of an eruption of a the Bardardbunga volcano in Iceland. If you are visiting this post looking for some more manly footage of volcano and do no mind spen

Technology for safety and a little bit of fun [Coffee-Byte]

We usually discuss science here and it can get a little heavy at times. So for a change, here is an application of technology for purposes of safety. No, this is not about driver less car that Google is making or some kind of hi-tech device that ensures safety in aeroplanes. This is for the safety of pedestrians at the riskiest place for them in the world, the traffic signals! The video comes from Smart , a smart car maker, which is part of the Daimler AG in Germany.

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.

Fish on Wheels

For all those who pet lovers, who would love their pet fish to be with them at all times, Studio Diip, a Netherlands based startup lets you buy a unique aquarium that will let your fish steer in any direction it wants. By using advanced computer vision technology, entrepreneurs at Studio Diip , were able to design an aquarium with wheels which moves in the same direction as the fish moves in the tank. Here is the video of how the technology works! Unfortunately, the company could not find enough investors for this crazy idea and the project has been stalled for a while. But in case you have deep pockets and the zeal to let your fish drive around the house, do contact the team at Studio Diip  to get this project started once again!

A raft like none other!

If you have always gloated about how intelligent humans are, how we have built, boats, houses, smartphones and computers for ourselves and how we have built communities to protect ourselves and to work together, well, you have never seen ants in action then! If you still do not believe us on this, ask yourself this is, Would you cross the Amazon with nothing but your large extended family or people in your neighbourhood.  Well, ants do! Here, this colony of ants migrate across the Amazon by making a raft out of themselves

Lightning charges Nokia Lumia!

Although it sounds like an advertisement for the mobile company, it is the work of the researchers at the University of Southampton that is creditable. Prompted by the phone company, the researchers attempted to charge a mobile phone using lightning as the source of energy. Photo Credit: Pete Hunt Lightning strikes the Earth around 40-50 times per second and each lightning bolt carries anywhere between 1000 - 5000 joules of energy, enough to send a tennis ball at 23,000 km per hour.  While we are aware of the energy potential of lightning, we have never managed to harness this energy because we do not know how to control it (much like Fire was for a man of Stone Age).  Through these efforts, Nokia and The University of Southampton are looking for ways to harness this energy and also charge phones wirelessly. (You can read more about it in our previous post, about wireless charging). While we might be decades away from harnessing this energy successfully for everyday

Dancing water on a hot pan - here's why?

Ever wondered why water droplets suddenly start dancing on a hot pan, while they simmer away most of the times.  As if they have a mind of their own, water droplets seem to act like this in a random fashion. Well, you are not the first one to have observed this or to have dismissed it as an random act. In the year 1796, Johann Leidenfrost, found some order in this randomness, which is now known as the Leidenfrost effect. Image from Wikipedia Initially, as a hot pan reaches the boiling point of water, water evaporates slowly. As temperature increases and goes beyond 100 degrees Celsius, water evaporates immediately, usually accompanied with a hissing sound. As the temperature is increased further, water continues to evaporate quickly, except that the water closest to pan heats up quicker, evaporates and makes a small cushion of vapour between the pan and water droplet. Since, vapour conducts heat poorly, heat from the pan takes much longer to reach and completely evaporate
