Several birds like chicken are distant relatives of dinosaurs that once ruled the land. A study at a University in Chile decided to check out the motion of chicken, if they were to walk less like birds and more like dinosaurs.
Map of the Internet by Jay Jason Simons presents a very vivid world imagined to originate from the world wide web. It is remarkable considering the sheer amount of imagination and hardwork that would have gone into creating this map. The main map was illustrated using popular web trends, technologies in use, Alexa rankings, and other metrics.
We eat sugar, we crave sugar. In this video Dr. Nicole Avena explains why we do enjoy sugar.
When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine — an overload of sugar spikes dopamine levels and leaves you craving more. Nicole Avena explains why sweets and treats should be enjoyed in moderation.
We know the solar system is flat, so are several objects in the universe like galaxies, and, as the video points out, Saturn’s rings. So why in the world did our solar system turn out to be flat, with all the three dimensional space available? The video explains it well. This also reminds us of this other video we saw some time ago. It explains similar ideas well enough, although for a two dimensional medium with focus on gravity.
First asteroid to be sighted this year was the 2014 AA, and it was also the first asteroid to enter the Earth’s atmosphere this year. Interestingly enough, this is only the second time ever that we have managed to see an asteroid, before it hit the planet, the first such instance being in 2008.
A team of researchers worked with more than 700 participants in Sweden, Finland and Taiwan to draw a heat map of what areas of the human body are effected with certain emotions. Participants viewed emotion-laden words, videos, facial expressions and stories, and self-reported the body parts that felt different after being exposed to the emotion stimulus.
Putting 3D Printing technology to greater use, scientists at the Australian Research Council Centre of Excellence for Electromaterials Science (ACES) have developed the BioPen. The pen follows a process similar to 3D printing to deposit regenerative stem cells onto damaged bone and cartilage.
It’s impressive how common, unassuming things around us work, and how little we often know about them. For example, flames that we often see are actually capable of conducting electricity. A flame is mostly composed of plasma where the ionized molecules and atoms can conduct electricity.
Cubli is a tiny cube, measuring just 6 inches for each side. But the tiny little cube is darn impressive, especially given its ability to maintain its balance. Cubli can balance itself on its corner, then you could push, goad, spin the little cube or even dramatically change the angle of the surface it sits on, but the cube staunchly refuses to budge.
We know gravity, but visualizing it on the fabric of space-time can be a bit daunting. This excellent video shows a simple way to visualize gravity, and on its way plays along with some pretty interesting facts and trivia. It is about 10 minutes long, but it is 10 minutes well spent.
