  • Climatic Dynamics of Monsoons – NASA SVS (2016)

    Climatic Dynamics of Monsoons – NASA SVS (2016)

    The monsoon was noticed for the first time in India. It is a seasonal rain and wind pattern that occurs in many places on our planet. The quasi-regular atmospheric pattern is hugely influential in Human history. The first truly global economy was established in the Indian ocean by sea faring merchants who traveled from Africa and middle east all the way to Indonesia and Malaysia and back. Predictability of the wind patterns around the Indian Ocean was the defining factor. […]

  • Seed Dispersal by Dung Mimicry – Nature (2015)

    Seed Dispersal by Dung Mimicry – Nature (2015)

    Plant-animal interactions have not always evolved to become mutualistic win-win strategies like birds dispersing seeds of palms while feeding on the fruits. Plants can be rather deceptive. They can hijact sensory vulnerabilities of animals. Secondary metabolites such as nicotine, caffeine, codeine can be rather addictive. Plant chemicals can also be used as deterrent. A sub-Saharan desert plant taily weed (Ochradenus baccatus) detonates a mustard bomb in the mouths of seed predators who dare to chew and destroy its seeds. Plant […]

  • Updates from NASA’s Curiosity Rover [Mars Science Laboratory]

    Updates from NASA’s Curiosity Rover [Mars Science Laboratory]

    Geological evolution of the Earth and Mars have started from very similar origins but yet the two planets have followed quite different trajectories. Geology of our planet has shaped the evolution of life (and vice versa). Understanding Mars will also help understand our own planet. For this reason, Nature Documentaries will be paying attention to this ambitious Mars rover project. Jet Propulsion Laboratory has been holding regular detailed update sessions. You can follow some of these updates below starting from […]

  • Domestication as a Signature of Human Nature / One Man and His Dog – BBC (1985)

    Domestication as a Signature of Human Nature / One Man and His Dog – BBC (1985)

    Johnny Wilson and his dogs earned their fame when they won BBC2’s One Man and His Dog competition. Here in this short clip we see a remarkable section from the program that highlights a signature of one of the hallmark characters in Human nature: Domestication. Domestication expanded Human abilities beyond the natural boundaries. Note that domestication in animals almost always starts with selection of “behavior”. Using this unintentional primary cue as a starting point Humans in different parts of the […]

  • Bacteria Evolution on a MEGA Petri Plate – Michael Baym – Harvard Medical School (2016)

    Bacteria Evolution on a MEGA Petri Plate – Michael Baym – Harvard Medical School (2016)

    The Microbial Evolution and Growth Arena plate (MEGA-plate) experiment designed by Harvard Medical School researcher Michael Baym and his coworkers is an absolutely fascinating demonstration of evolution in action. They were able to visualize with a stunning didacticity (is that a word?) how bacteria evolves resistance to the antibiotic trimethoprim surprisingly fast for the Human time scale. The experiment is reminiscent of a highly simplified 2-D version of a long-term evolution experiment by Richard Lenski of the Michigan State University. […]

  • Welcome to the Anthropocene – a Film About the State of the Planet – UN Rio+20 Summit (2012)

    Welcome to the Anthropocene – a Film About the State of the Planet – UN Rio+20 Summit (2012)

    Due to Human activities our planet has now reported to have entered into a “no analog state”. This means our planet has never experienced fast changing present-day conditions in its geological and evolutionary history. The closest geological event to what is happening now is known as (PETM) Paleocene-Eocene Thermal Maximum. PETM took place 56 million years ago. Changes happening now is way too fast, much faster than those in PETM. We are indeed in a no analog state in ecological […]

  • Observations and Simulations of 2005 Atlantic Hurricane Season by NASA

    Observations and Simulations of 2005 Atlantic Hurricane Season by NASA

    Atlantic hurricane season typically starts from June 1 and ends in November 30 in the northern Atlantic. There’s a noticeable peak from late August through September. Each season peak activity occurs around September 10th. During the 2005 Atlantic hurricane season there was an unusually high cyclone activity surpassing any other season. The number of category 5 hurricanes, and the most intense hurricane ever measured (Hurricane Wilma) by atmospheric pressure was recorded during this time period. The visualization ’27 Storms: Arlene […]
