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

  December 12, 2015 at 7:00 pm / Evolution, Natural history, Nova Documentaries, PBS Nature, Video, Wildlife Documentaries

  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 […]

  Grass: A Nation’s Battle for Life (1924)

  November 19, 2015 at 12:13 pm / Human Nature, Technical Notes, Video

  Filmed on location between Turkey and Iran, Grass is an amazing first ethnographical account of nomadic Bakhtiyari people. The subjects of this film later also were revisited by landmark documentaries like the “Harvest of the Seasons” episode of the Charles Bronowski’s Ascent of Man series in 1973. Similarly, Akira Kurosawa’s 1975 film Dersu Uzala, centered around an aboriginal Nanai tribesman and Werner Herzog’s Happy People (2013) are productions in this tradition. The film is contemporary to Robert Flaherty’s Flaherty’s Nanook […]

  A Tribute to Jacques-Yves Cousteau: Cries from the Deep (1981)

  November 10, 2015 at 12:42 pm / Ecological Documentaries, Human Nature, Natural history, Video

  Ever since the publication of his first book titled “The Silent World” in 1953 Jacques Yves Cousteau has generated multiple waves of inspiration worldwide. A documentary produced under the same title won the prestigious Palm d’Or award at Cannes Film Festival in 1956. This is a rare achievement among nature documentaries. Cousteau’s second big hit arrived in 1965 with another production titled World Without Sun documenting activities of six crew members living in Continental Shelf Station II at 10m depth […]

  Leonardo Da Vinci the Anatomist – Nature Video

  October 27, 2015 at 7:47 pm / Human Nature, Video

  Leonardo da Vinci transformed natural sciences by his careful observations, experiments and illustrations. He distinguished himself in the harsh world of the Medici ruled 16th Century Florence in the aftermath of the fall of Constantinople. In this video by Nature Magazine, Senior Curator Martin Clayton exlains three of Leonardo’s most intriguing anatomical studies. Today, Leonardo’s drawings kept in solander boxes in the Print Room in the Royal Library at Windsor Castle. A selection of his drawings is on display in […]

  Secrets of the Hive – Why Puerto Rico’s Killer Bees Stopped Killing – Smithsonian Institution (2015)

  October 27, 2015 at 1:04 am / Ecological Documentaries, Evolution, Human Nature, Natural history, Video, Wildlife Documentaries

  Secrets of the Hive is a Smithsonian Institution documentary directed by Dennis Wells. It focuses on the decline of the honeybees and reviews potential solutions to restore pollination service provided by these important domesticated insects. A major emphasis of the documentary is on the Africanized honeybees. These bees are a result of a failed experiment that started with good intentions in Brazil. Researchers in 1950s wanted to introduce the genetic vigor lost in honeybees due to domestication. Trials to selectively […]

  DNA transcription as the First Step of the Central Dogma of Biology | HHMI (2015)

  October 24, 2015 at 1:26 pm / Evolution, Molecular Nature, Video

  What reads the information stored in our genes? How is it read? DNA transcription is the first step. Transcription is an amazingly beautiful process that take place in every (every!) living cell. In this animation produced by the Howard Hughes Medical Institute – HHMI you can see how a multi-part enzyme called RNA Polymerase II reads and writes the information stored in DNA into RNA. This is the first step of the Central Dogma of biology. RNA polymerase is a […]

  A Movie of RNA Polymerase II Transcription – Cheung & Cramer (2012)

  October 6, 2015 at 3:54 pm / Molecular Nature, Video

  This unnarrated molecular animation by Alan Cheung and Patrick Cramer details the first step of the Central Dogma of biology where the messenger RNA becomes synthesized from it’s DNA template. Enzymes that read information on DNA and produce the RNA counterparts are known as RNA polymerases. There are three types of RNA polymerase enzymes (RNA polymerase I, II and III). Here the working mechanism of type II that reads protein coding genes is shown based on multiple scientific studies spanning […]

  Common Mallow Pollinated by Dagger Fly

  October 4, 2015 at 7:05 pm / Natural history, NatureDocumentaries.org, Short Observations, Video

  Common Mallow (Malva neglecta) Pollinated by Dagger Fly (Empididae). Filmed on 2015 May 12th, in Postacı Halil sokak Ferahevler, Istanbul. When the talk subject comes to pollination the buzzing image of bees appear in our heads. Yet, many other insect groups contribute to the pollination service including flies (Diptera). Here you can see a dagger fly (it is also known as dancing fly) visiting an edible wild plant the common mallow (Malva neglecta). Dagger flies may not appear to be […]

  Dagger Flies (Empididae) Mating with Nuptial Gift

  October 4, 2015 at 7:05 pm / Ecological Documentaries, Natural history, NatureDocumentaries.org, Short Observations, Video, Wildlife Documentaries

  Dagger flies Mating. Filmed in Sami Dino Parkı, Ferahevler, İstanbul on May 12th 2015. Male hilarine flies (Diptera: Empididae: Empidinae) present their mates with silk-wrapped gifts. The nuptial gift keeps the female busy during copulation. The silk around the gift is produced by specialized cells located in the foreleg basitarsus of the male fly. Here in this observation the hind legs of the male appear to have multiple functions: They form a resting platform for the female and at the […]

  Planet Ant – Life Inside the Colony BBC (2012)

  October 2, 2015 at 10:39 pm / BBC documentaries, Ecological Documentaries, Evolution, Natural history, Video, Wildlife Documentaries

  Self-organization skills of ants are impressive. How do they achieve such large-scale project management? Without central control individual behavior of each worker ant contributes to the collective emergent behavior. Once they discover a resource they are extremely efficient in utilizing it. We have a lot to learn from them. This documentary is quite unique in its approach. It documents an entire leafcutter ant colony (Atta cephalotes) re-organize itself from scratch in an artificial nest purposefully built to observe colony-scale behavior […]

  Life in the Universe – The Economist (2015)

  October 2, 2015 at 1:53 pm / Evolution, Molecular Nature, Video

  Does life exist outside of our planet? If so, are there intelligent life forms out there? How did life get started on our World? The Economist makes a quick tour of scientists who have been working on such questions. Frank Drake in his famous 1961 “Drake Equation” stated that the number of life-bearing planets must be a function of their host stars. How many planets have formed around those stars, what fraction of those planets are suitable for life, on […]

  What Caused the Cambrian Explosion? – The Economist (2015)

  September 3, 2015 at 4:33 pm / Evolution, Global Patterns

  It was a big curiosity for early geologists. For roughly 90% of the Earth’s history it appeared as if there was no life. After this long static period at about 542 million years from present life forms as we know of today began to appear bursting over a relatively short time (over 20 million years). Colloquially, this time period is called “Cambrian Explosion”. All of these life forms were of course aquatic: Annelids, arthropods, brachiopods, echinoderms, molluscs and ancestors of […]
