  • Hotel Heliconia – Phil Savoie (2001)

    Hotel Heliconia – Phil Savoie (2001)

    Filmed on location by Philip Savoie and his filming crew at La Selva Biological Field Station in Costa Rica, this documentary provides a great crossection of life weaved around the Heliconia (Heliconiaceae) plant. Plants provide an effective template to convey many interrelated natural history observations. However they rarely become center of attention in wildlife documentaries (but see Plants R Cool 2!). Unlike documentaries jumping from one continent to the other following a global theme, Hotel Heliconia follows a very detailed […]

  • Total Solar Eclipse in North America – Path of Totality – NASA/SVS (2017)

    Total Solar Eclipse in North America – Path of Totality – NASA/SVS (2017)

    During the August 21, 2017 total solar eclipse, the Moon’s umbral shadow will traverse across the North American continent, from Oregon to South Carolina. Transition from west to east coast will last a little over 90 minutes. Along the path of totality, observers will see the Moon completely obscure the Sun for about two and a half minutes. The math used to calculate the trajectory of the eclipses to create maps such as the one featured here was worked out […]

  • How We Measure Photosynthesis – NEON Education (2014)

    How We Measure Photosynthesis – NEON Education (2014)

    National Ecological Observatory Network (NEON) is a large collaborative group of long-term ecological research sites spread over 81 locations in the United States including Harvard Forest and Smithsonian Ecological Research Center (SERC). This video is a part of the educational portfolio by NEON showing how researchers measure photosynthesis at single leaf level using infra red gas analyzers. Understanding photosynthesis at leaf level enables scaling up and extrapolate photosynthesis at forest level. Infact, there are computer models that treat forest canopies […]

  • Your Inner Fish – Neil Shubin – PBS (2014)

    Your Inner Fish – Neil Shubin – PBS (2014)

    Your Inner Fish, is the first installment of a three part PBS series by Neil Shubin. After a quick review of our shared anatomy with the fish and a whirlwind tour along the evolutionary timeline, the program plunges us into the fascinating saga of discovery of the tetrapods that explains how limbs of the terrestrial vertebrates came to be. Watch how the legendary 375 million year old (Devonian) tetrapod fossil Tiktaalik was discovered after a series of adventurous Arctic expeditions. […]

  • Cloud-Aerosol Transport System (CATS) on Board ISS – NASA/SVS (2017)

    Cloud-Aerosol Transport System (CATS) on Board ISS – NASA/SVS (2017)

    NASA’s Cloud-Aerosol Transport System is a remote-sensing instrument installed on the International Space Station (ISS) in 2015. Using LIDAR technology it scans a vertical slice of the atmosphere for natural as well as human made aerosols and clouds. The near-real-time data transmitted from the ISS enables CATS team to process it within six hours. One of the natural aerosol sources is volcanoes. In April 2015, the CATS instrument provided a detailed profile of the south Chilean volcano Calbuco when it […]

  • Dingo of the Australia – Adam Geiger (2013)

    Dingo of the Australia – Adam Geiger (2013)

    Dingo (Canis lupus dingo) appears in the archaeological record of Australia at 4230 years before present. They ruled the continent as apex predators together with the now extinct Tasmanian tiger within the last few thousand years. Dingoes successfully colonized the continent spreading into diverse habitats including tropical rainforests, temperate Eucalyptus forests, mountainous highlands and grasslands. The only exception is the dry inhospitable central deserts. Dog domestication is the earliest among other animals going back to 40,000 years ago. The Dingo […]

  • The Central Dogma of Biology – Kazufumi Watanabe (2008)

    The Central Dogma of Biology – Kazufumi Watanabe (2008)

    Riken Omics Center from Japan presents a well-crafted animation that summarizes one of the most important subjects of biology since 1958. The central dogma is our first systematic approach in understanding nature of the information flow and manufacture of structures within a living cell. The viewer must be warned that the structures in this animation are artistic representations and in reality they look quite different from space ships. For example RNA Polymerase II is one of the most well-studied enzymes […]

  • The World’s Most Boring TV … and Why It’s Hilariously Addictive – Thomas Hellum – TED Talk (2014)

    The World’s Most Boring TV … and Why It’s Hilariously Addictive – Thomas Hellum – TED Talk (2014)

    The idea of “slow-TV” was there. For years live cameras have been showing bears hunt fish in rivers, birds nesting and rearing their chicks with viewers in the millions. A Discovery Channel series called “Earth Sunrise” recorded a full hour of realtime sunrise in spectacular locations from around the world. Recording of a total solar eclipse in Brazil and Turkey was quite a memorable event. Slow-TV concept is a paradigm invented by real-time nature observers. The Norwegian television producer Thomas […]
