Weekend Video: Ride of Passage

In my last post, I talked about world’s smallest and  cutest chameleon. Now it’s time to watch some cute animated chameleon in this issue of weekend video.

Story: Toki’s tribe expects him to bring home the head of the biggest animal possible. In return, he will receive honor and respect. However, this rite of passage does not turn out as planned. With the help of a colorful new friend, he achieves something much bigger.

Picture of The Day: Cliff Climibing Polar Bear

This is an award winning picture by photographer Jenny E. Ross where a polar bear can be seen carefully climbing the cliff above the ocean to feed on seabird eggs. Typically polar bears feed on sea seals but due to climate change and subsequent melting and receding of the polar ice it has been unable to find it’s natural food. This is a desperate attempt by the bear for it’s survival. The picture won the world press photo award in Nature category.

Meet World’s Smallest Chamaleon (Brookesia et al.)

In a  recent discovery, researchers from Germany and USA have found world’s smallest and cutest species of  chameleon. These species also rank among world’s smallest reptile. These chameleons belong to group Brookesia minima and are found mostly in northern Madagascar region.  Four newly discovered species have been named Brookesia micra, Brookesia tristis, Brookesia conifdens, Brookesia desperata. The maximum length of newly discovered species ranges between 22-48 mm. Brookesia micra, shown above, is the smallest of the group (maximum size 30 mm). These miniscule leaf chameleons have all the features and properties as you can find in any regular size chameleon- can rotate their eyes  independent of each other, can camouflage when in danger or looking for food, can grab things using their tail and have projectile tongue to capture their prey. As mentioned earlier, the habitat region of these species is very small. All of them are found in a very small region of Madagascar and if this habitat is destroyed, we will lose this species forever. Lead researcher, Glaw, named the species keeping this issue in mind. For eg. the word tristis in Latin means sad, sorrowful which reflects the sad situation of massive deforestation of this region even after the region have been declared a nature preserve. Name desperata also reflects the sad situation of deforestation of the area where Brookesia desperata is found. These names might be world’s most sad names ever given but it also reflects the sad state of affairs of species preservation all around the world. Luckily,  Brookesia confidens is found in the area where limestone formations have made the area very hard to access by the humans and therefore there is a hope that this species might be protected just due to natural protection.

Keck In Motion

I have posted about Very Large Telescope (Chile) in past, this time posting a beautiful video showing Keck observatory in action. Keck observatory is located at the summit of dormant volcano in Hawaii and is used for probing our near and distant universe with great precision (nanometer precision level). The observatory hosts worlds largest optical and infrared telescopes; telescopes are about eight storeys high and weigh more than 300 tons while the diameters of their primary mirror are about 10 m! The telescope uses adaptive optics (AO) which changes it’s shape depending on changes in environmental conditions and thereby eliminates any kind of aberrations or distortions in images resulting from turbulence in earth’s atmosphere. For adaptive optics to work, a bright, nearby reference star is required but since bright stars are limited in the sky, astronomers at Keck have created their own little neighborhood star– by using a laser and exciting sodium atoms in upper atmosphere (90 km above the earth’s surface) resulting in  a bright artificial star which adaptive optics can use as their reference. In this cool video, you can see the Keck observatory in action. In the beginning of video, you see the hexagonal object, that’s the keck 2 telescope. Enjoy the video along with the cool music!

# IAmScience

“Magical things can happen when you enthusiastically open your mouth on the internet.” – Kevin Zelnio

Science writer and marine biologist Kevin Zelnio started the Twitter hashtag #IamScience last month, encouraging scientists to share their individual stories about their traditional or unconventional paths that brought them to where they are today. The response was overwhelming, with hundreds of tweets pouring in over just a few days.Mindy Weisberger compiled some of the tweets and added Reckless Kelly’s “Wicked Twisted Road” to create this video. If readers of this post can share their thoughts about how they got into their profession including science that would be great.

The Proof From The Book

Abstruse Goose comic strip is simply awesome. Here is the Riemann Hypothesis, postulated in 1859,  which is also one of the seven millennium prize problems:

Some numbers have the special property that they cannot be expressed as the product of two smaller numbers, e.g., 2, 3, 5, 7, etc. Such numbers are called prime numbers, and they play an important role, both in pure mathematics and its applications. The distribution of such prime numbers among all natural numbers does not follow any regular pattern, however the German mathematician G.F.B. Riemann (1826 – 1866) observed that the frequency of prime numbers is very closely related to the behavior of an elaborate function

    ζ(s) = 1 + 1/2s + 1/3s + 1/4s + …

called the Riemann Zeta function. The Riemann hypothesis asserts that all interesting solutions of the equation

    ζ(s) = 0

lie on a certain vertical straight line. This has been checked for the first 1,500,000,000 solutions. A proof that it is true for every interesting solution would shed light on many of the mysteries surrounding the distribution of prime numbers. [Clay Mathematics Institute]

Stylish Java Sees Dark Side of Doritos

I am working on a paper but apparently my idea machine is on a sleeping mode, time to get a coffee. Meanwhile you guys can enjoy these beautiful art works by Brock Davis. His creative artwork combined with a hot coffee (sans stylish jacket) might do the trick and help me in finishing the paper. I wish I could get ideas like Brock- by looking at simple things like coffee jacket and broccoli and Doritos and convert it to something beautifully amazing. Last picture is a recreation of album cover of Pink Flyod’s Dark side of moon. He used bags from different flavors of Doritos and cut it to get all the different colors and created “Dark side of Doritos”. Amazing!
