  • Acid Attack

    Acid Attack

    Nectar is an effective concoction for establishment and maintenance of plant-animal interactions. Using nectar, plants can build a community of allies for defense and even manipulate the behavior of pollinators. We are accustomed to nectaries found in flowers. Plants however, have evolved nectaries in other locations in their above-ground parts including the base of the flowers and petioles. These are called extrafloral nectaries. The sugary reward coming from the extrafloral nectaries invites ants to defend them. Here we can see […]

  • Prominent Features of Leaf-footed Stinkbugs

    Prominent Features of Leaf-footed Stinkbugs

    The leaf-footed stinkbugs have quite a few eye-catching body features including highly specialized mouthparts, offensive and defensive adaptations. This is an order of insects on which evolutionary pressures are visibly active shaping their morphologies. The evolutionary trade-offs underpinning these structures are an active research subject by biologists. Here, three characteristic body parts in leaf-footed stink bugs are highlighted: The labium, the pronotum and the components of the hind leg (femur and tibia). Entomologically, the femur and the tibia are the […]

  • Stalking Seal on the Spring Ice – Quentin Brown & Asen Balıkçı (1968)

    Stalking Seal on the Spring Ice – Quentin Brown & Asen Balıkçı (1968)

    Diverse ways of sustenance on the frontiers of the world fascinate us about Human adaptability and effective resource use. Stalking for seals on sea ice is one of the best documented hunting technique which employs quite exceptional behavioral deception tactics. The hunter uses a cognitive ability called “theory of mind” to overcome behavioral tripwires for prey to escape. The hunter projects the world from the view point of the prey and adjusts own behavior to a successful intercept. The hunter […]

  • Newtok | The Water is Rising / Patagonia Films (2022)

    Newtok | The Water is Rising / Patagonia Films (2022)

    Human induced climate change is creating fast coastal landscape changes and during that process turn many indigenous communities into climate refugees. Co-directed by Michael Kirby Smith and Andrew Burton, Newtok | The Water is Rising highlights demise of a population. Rising sea levels threaten Newtok, Alaska. The Arctic permafrost is melting at an increasing rate. Due to Polar Amplification the speed of climatic change in the Arctic is rather fast. To keep their culture and community intact, the Yup’ik residents […]

    Bacterial Type 4 Secretion System – Gabriel Waksman (2018)

    Gram negative bacteria Type 4 Secretion System (T4SS) by Dr. Gabriel Waksman of the Institute of Structural and Molecular Biology, University College London and Birkbeck. Animations by Cellscape. This playlist consists of three videos illustrating the type 4 secretion system (T4SS) assembly, pilus biosynthesis and transfer of DNA segment into a recipient cell. T4SS are bacterial macromolecule secreting structures. These macromolecules include proteins and DNA. Bacterial cell-to-cell exchange of genetic materials such as plasmids or mobile genetic elements is called […]

  • Popped Secret: The Mysterious Origin of Corn – Nathan Dappen & Neil Losin – HHMI (2015)

    Popped Secret: The Mysterious Origin of Corn – Nathan Dappen & Neil Losin – HHMI (2015)

    Domestication of plants and animals is a key transformation in recent Human evolutionary history leading to sedentary farming societies. Domestication of Maize particularly followed a different trajectory from the agricultural crops of the old world. This HHMI documentary tells how the ancestral wild grass called Teosinte was domesticated to evolve into Maize. In the old world, most domesticated grasses had a surprisingly similar “first step” that paved the way towards agriculture. In old world grasses including rice, wheat, barley and […]

  • Great White Shark Pup off the Northern Aegean Coast of Turkey

    Great White Shark Pup off the Northern Aegean Coast of Turkey

    Be prepared to hear a fascinating piece of natural history about the Mediterranean great white sharks (Carcharodon carcharias). The story is fascinating for multiple reasons. First, the great whites are one of the most charismatic, vulnerable, cryptic and misunderstood predator fish species. Second, it takes place in a quite unexpected location. Altınoluk is a town on the northern Aegean coast of Turkey. It is located to the south of Troy on a legendary sea route known as the Argonaut route […]

  • Antifreeze Proteins in Virtual Reality – Nanome (2022)

    Antifreeze Proteins in Virtual Reality – Nanome (2022)

    Dr. Mike Kuiper, a biomodeler at CSIRO’s Data61 explains how antifreeze proteins work in a metaverse compatible virtual reality environment enabled by Nanome. These ice structuring proteins, is a basis of survival for organisms evolved to live in very cold environments with temperatures below the freezing point of water. Essentially, these proteins can bind to the surface of ice crystals and create a surface effect leading to freezing-point depression. Bacteria, insects, fishes and many more organisms from different evolutionary backgrounds […]

  • A Frequently Yawning Rough Green Snake (Opheodrys aestivus)

    A Frequently Yawning Rough Green Snake (Opheodrys aestivus)

    This beautifully bright green snake is a master of disguise. Although they are fairly long (can be up to 81 cm) it is almost impossible to notice them unless you have been curiously scanning the vegetation with a purpose. The Rough Green Snake (Opheodrys aestivus) is behaviorally very docile. It must be a slow day for this particular individual since s/he was frequently yawning. The observation was recorded on 9th of September 2012 at the Georgia State Botanical Garden in […]

  • Grey Reef Sharks Mating – Yann Hubert

    Grey Reef Sharks Mating – Yann Hubert

    Shark life cycle has many elusive stages. Mating is one of these secretive moments. Here in this short observation filmmaker Yann Hubert captures a pair of Grey Reef Sharks (Carcharhinus amblyrhynchos) during copulation. Characteristic clasper organs used by the male to latch onto the female during copulation is very striking. The location and time of the year in this extremely serendipitous encounter is not specified perhaps to avoid disturbance from many curious divers. Grey Reef Sharks are common and live […]

  • Cone-headed Planthoppers (Acanalonia conica) on Passion Flower

    Cone-headed Planthoppers (Acanalonia conica) on Passion Flower

    This observation has been registered in the iNaturalist database with the following accession 105647409. Observed on August 9, 2014 at the Georgia State Botanical Garden in Athens, GA, USA. Here, you can see a number of cone-headed planthoppers (Acanalonia conica) feeding on a passion flower vine (Passiflora incarnata). The passion flower family (Passifloraceae) is well known for its sugar producing glands called extrafloral nectaries. These nectaries attract ants and here in this observation we see two species of ants (Formica […]

  • Ants Defending Plants

    Ants Defending Plants

    Plant eaters are called herbivores and they pose a threat for plants. Understandably, nobody would like to get eaten. In order to prevent tissue loss and damage from herbivores plants have evolved defensive adaptations such as hard to digest tissues and poisonous chemicals. Some plants however, have evolved a different solution. Plants can use nectar as drivers of beneficial behaviors such as pollination and protection from herbivores. Nectar is an attractive fluid for many animals. It is a rich calorie […]

  • Live from Geldingadalir Volcano, Iceland (2021)

    Live from Geldingadalir Volcano, Iceland (2021)

    Be it Mount Ararat or Mount Chimborazo, every massive stratovolcano was once upon a time a tiny little pimple on the Earth’s surface. It is most certainly very fascinating to see a baby volcano being born, a geological process that will last a very long time. The first technical description of lava flow comes from the ancient geographer Strabo of Amaseia. In his book, he describes the Katakekaumene, which means the “burnt country” referring to a region of around 1,800 […]
