    Australian Walking Stick Insects are Three Times Weirder Than You Think | PBS – Deep Look (2022)

    It is a seed, no it is an ant, no it is a leaf, no it is a stick,… Actually, it is all of the above through a temporally spaced sequence of disguises (*): It is the Australian walking stick (Extatosoma tiaratum). This insect is indeed a master of deception. It is a fascinating example of a series of adaptations that maximized its survival by multiple versions of mimicry successfully fooling predators at every stage of their life cycle. (*) […]

  • Visiting the most vulnerable place on Earth: the ‘doomsday glacier’ – PBS Newshour (2020)

    Visiting the most vulnerable place on Earth: the ‘doomsday glacier’ – PBS Newshour (2020)

    For a little over more than 33 million years, the Antarctic continent remained an exceptionally isolated land mass due to the Antarctic Circumpolar Current that forms a thermal shield around it. The Antarctic Circumpolar Current is the strongest ocean current on our planet flowing without obstruction from any other land masses. Unfortunately human induced global warming is changing all that and the effects of the climate change is being felt at both poles of the planet through a phenomenon known […]

    Decoding COVID-19 – Sara Holt | NOVA / PBS (2020)

    Center for Disease Control (CDC) has been one of the most effective institutions in fight against emerging diseases. Yet, strikingly, the US has become the epicenter of the COVID-19 pandemic. Elimination of the immensely important the Global Health Security and Biodefense unit — responsible for pandemic preparedness — established in 2015 is now deemed one of the biggest political mistakes of our time. Unfortunately political interference continued to render experts of this most cutting edge organization largely ineffective and left […]

  • NOAA Hurricane Hunters – PBS NewsHour (2018)

    NOAA Hurricane Hunters – PBS NewsHour (2018)

    Every hurricane season a fleet of “Hurricane Hunter” planes are deployed to “airtruth” the atmospheric conditions of storms long before they make a landfall. A pair of Lockheed P3 Orion turboprop planes nicknamed “Kermit and “Miss Piggy” are among them. Hurricane Hunter missions are crucial to verify and fine-tune satellite measurements. Hurricane Hunters fly directly into the hurricanes and traverse the eye of the storm several times in order to collect atmospheric data equipped with airborne Doppler weather radar. During […]

  • Whack! Jab! Crack! It’s a Blackback Land Crab Smackdown – Deep Look – PBS/KQED (2019)

    Whack! Jab! Crack! It’s a Blackback Land Crab Smackdown – Deep Look – PBS/KQED (2019)

    DEEP LOOK is an award-winning PBS program produced by KQED. Here’s another cool story from season 5 Episode 13. Shred a sponge into thousands of pieces but the cells can still rearrange and organize themselves in a surprisingly rapid manner. Here we are shown a snapshot of another example of limb regeneration from the crustacean blackback land crab (Gecarcinus ruricola) native to the Caribbean. Human tissue and organ regeneration is a curious goal for medicine. However in order to achieve […]

  • Let Them Eat Flies! KQED/QUEST (2014)

    Let Them Eat Flies! KQED/QUEST (2014)

    Insects are a hugely successful group of organisms. Their evolution transformed life on land immensely especially influencing flowering plant evolution. Insects also play a large role as food sources. Here in this KQED documentary we see how a fly farm in Ohio rears a common insect, the black soldier fly (Hermetia illucens) to be used as food for fish farms. Some City farms have successfully been growing fish beneath the plants which helps recycling of nutrients reducing fertilizer use. Aquaponics […]

  • What Gall! The Crazy Cribs of Parasitic Wasps – Deep Look – PBS/KQED (2015)

    What Gall! The Crazy Cribs of Parasitic Wasps – Deep Look – PBS/KQED (2015)

    Another fascinating episode from a series produced by PBS/KQED: Deep Look… Gall formations are indeed one of the most interesting examples of plant-animal interactions. Gall-inducing wasps are plant parasites. The larvae hijack the chemical signaling pathways by secreting two plant hormones auxin and cytokinin which induce abnormal cell divisions leading to gall formation. In certain instances anthocyanin production pathways become upregulated and this gives most of the gall tissues their characteristic red color. Larvae also induce sugary secretions and literally […]

    Run Hide be Invisible – Revealing the Leopard – PBS/NATURE (2010)

    The Leopard (Felis pardus Linnaeus, 1758) is one of the most successful big cats of our time. It’s ability to adapt to different climates and habitats enabled spreading out of Africa into Asia. They live in diverse habitats such as forests, subtropical and tropical savannas, grasslands, rocky and mountainous regions, and even deserts. The leopard can live in both warm and cold climates. It has a very broad food base ranging from insects to large mammals. In Africa this cat […]

  • Leave It to Beavers – PBS (2014)

    Leave It to Beavers – PBS (2014)

    There are two species of beavers in the temperate zones of the world. North American (Castor canadensis) and Eurasian (Castor fiber) beavers were almost exterminated to extinction. These rodents are the largest after the tropical capybara that lives in wetlands of the South American tropics. Now bouncing back from extinction beaver populations are recovering under protection. Beavers are being recognized as keystone species by ecologists and conservation biologists. As habitat constructors and brilliant hydro-engineers, beavers can recharge water tables and […]

  • Learning to Live on the Moon – PBS

    Learning to Live on the Moon – PBS

    Energy flows, nutrients cycle. This is how we can define working principles of an ecosystem in a nutshell. Our planet has a very complex land-air-water interaction and we are only beginning to understand the behavior of these systems by simplifying them in enclosed systems such as Landscape Evolution Laboratory (LEO). Due to its proximity, the Moon appears to be the most convenient celestial body to colonize. The Moon is so close that it can even occasionally get shielded by the […]

  • Coelacanth: The Fish That Time Forgot – PBS NOVA (2001)

    Coelacanth: The Fish That Time Forgot – PBS NOVA (2001)

    Coelacanth morphology and genome has been extremely informative in understanding tetrapod evolution. Marjorie Courtenay-Latimer was the curator of a natural history museum in East London. In 1938 a local fisher brought a curious fish specimen which was to become a major discovery in evolutionary biology. Latimer described the fish as Latimeria chalumnae. The fish was over 1 m long, bluish in color. Most interestingly it had fleshy fins that resembled the limbs of terrestrial vertebrates. The discovery was a hugely interesting […]
