Sharing The Secrets – Drew Perlmutter (2015)

January 7, 2018 at 10:11 am / Ecological Documentaries, Video

Caves are powerfull places. Our ancestors were inevitably attracted to these geological formations. Prehistoric cave art that has flourished within the last 50 thousand years is an exciting demonstration of our ancestral relationship with these places. The filmmaker Drew Perlmutter brings the story of cave explorers in “TAG” region to the surface. The geology of the Tennessee, Alabama and Georgia is quite unique that has lead to many cave formations. In fact, the region is home to the highest concentration […]

The Tiniest Fossils – Shelf Life/AMNH (2017)

January 3, 2018 at 9:20 pm / Evolution, Natural history, Video

Foraminiferans or “forams” are extremely fast responding single-celled shelled organisms to climatic changes. They can be extremely small for one could easily mistake foraminifera fossils for flecks of dust. Over thousands and millions of years these tiny specimens adjusted their shapes based on Earth’s climatic fluctuations. Here in this AMNH production scientific assistant Bushra Hussaini, researcher Ellen Thomas, curator Neil Landman, and intern Shaun Mahmood show how they are preserving this invaluable collection. Forams initially were mistaken for another kind […]

Collecting the World: Inside the Smithsonian – Great Big Story (2017)

January 2, 2018 at 7:46 pm / Evolution, Natural history, Video

The Smithsonian National Museum of Natural History (NMHM) in Washington D.C. was visited by more than 7.1 million people in year 2016. The museums rich collection has over 144 million different artifacts. Only a very small fraction (less than 1 percent) of these collections are on display to the public. The bottom of the iceberg, the 99 percent of the Smithsonian’s treasures remain behind the scenes. Scientists and curators work with these objects to study and understand the world we […]

What is the Tragedy of the Commons? – Nicholas Amendolare | TED-Ed (2017)

January 1, 2018 at 8:46 pm / Ecological Documentaries, Human Nature, Video

The tragedy of the commons is an economic hypothesis popularized in 1968 by ecologist Garrett Hardin. The concept was examined in a 1987 BBC documentary called “Nice Guys Finish First” by Richard Dawkins with a game theoretical framework. The Tragedy of the Commons predicts ecological degradation due to human conflict of self-interest over the long-term well-being of their community. There are many examples of common resource exploitation such as destruction of cashew trees in Mozambic. However, this theory was heavily […]

Kīlauea Summit Eruption | Lava Returns to Halemaʻumaʻu – USGS (2017)

January 1, 2018 at 12:18 pm / Global Patterns, Video

The sight of liquid molten rock is a stunning experience and has inspired many filmmakers to capture it. The Greek geographer Strabo provides the first historical and technical account of a lava field from a belt of extinct volcanoes in Turkey. This area is now declared as a UNESCO World Heritage Site. In March 2008, a new volcanic vent opened within Halema‘uma‘u, a crater at the summit of Kīlauea Volcano in Hawaiʻi Volcanoes National Park on the Island of Hawaiʻi. […]

The Lava Affair – SKUNK BEAR/NPR (2015)

December 31, 2017 at 10:34 pm / Global Patterns, Video

Continents float on a massive ocean of magma and lava is what we observe when it reaches to the surface. The first technical description of lava flow comes from the Greek geographer Strabo in his book. He describes the Katakekaumene, which means the “burnt country” referring to a region of around 1,800 km2 in western Anatolia. The region harbors a dormant volcanic belt within the town of Kula which has been declared as a UNESCO World Heritage Site. The volcanism […]

The Lichenologist – Matthew Killip (2017)

November 28, 2017 at 7:56 pm / Ecological Documentaries, Evolution, Natural history, Video

This is the second installment from the filmmaker Matthew Killip following the “-omist/ogist” theme. Evolution of cooperation is a curious subject for biologists. The evolution of cooperation is investigated within the framework of game theory and has been encapsulated in a 1987 BBC documentary called “Nice Guys Finish First” by Richard Dawkins. How do organisms belonging to different kingdoms coordinate to live together? What are the rules of symbiosis? Lichens provide this type of study system where algae and fungi […]

The Anomalies: Acorn Woodpecker – Nate Dappen & Neil Losin (2017)

November 28, 2017 at 11:48 am / Ecological Documentaries, Evolution, Natural history, Wildlife Documentaries

Acorn Woodpeckers (Melanerpes formicivorus) are quite distinctive from other woodpecker species: They are communal. How did the cooperative behavior evolve? Biologists are working on answers for this curious question. Evolution of cooperative behavior is a matter of game theory and has been encapsulated in a 1987 BBC documentary called “Nice Guys Finish First” by Richard Dawkins. One of the most ubiquitous example for cooperative behavior comes from ants. Why do certain individuals altruistically give up their reproduction and help others? […]

Cave of Forgotten Dreams – Werner Herzog (2010)

November 23, 2017 at 8:02 pm / Human Nature, Video

Since its discovery in 1994 it was quickly realized that the Chauvet Cave of France harbors one of the most impressive art ever been studied belonging to Aurignacian. The Werner Herzog documentary articulates the findings in his characteristic story telling style. Archeologists had a bitter experience in opening such caves to public. The Lascaux cave paintings have been sadly damaged beyond repair due to increased humidity from visitors breath. Happily we can take a virtual tour of the Chauvet cave […]

Chain Forming Leptogenys Ants from Cambodia – Stephane de Greef (2014)

November 15, 2017 at 10:00 pm / Ecological Documentaries, Natural history, Short Observations, Video, Wildlife Documentaries

The ant behavior described in these observations were first recorded by citizen scientists in Cambodia (see the original recording at the end of this post) where ants have been shown to form chains to transport large prey. The level of cooperation is so striking that myrmecologists scrambled to find out whether it is genuine. Two researchers have successfully documented the behavior by filming them in Angkor Thom, Siem Reap, Cambodia. Self-assembling cooperation in ants is known to take many interesting […]

48 Cantones: The Mayan Forest – Thomas & Julian Moll-Rocek (2014)

November 10, 2017 at 8:11 pm / Human Nature, Video

In their documentary, Thomas & Julian Moll-Rocek explore the Mayan Cosmovision. For Meso-Americans this is a worldview that integrates the structure of space and rhythms of time into a unified whole. In Guatemala’s western mountains, in the state of Totonicapán, a large community forest has prospered for centuries adjacent to densely populated valleys. The Mayan forest cover the hills and the mountain ridge. The management of local resources by the Mayan community provides a counter-argument for the ‘tragedy of the […]

Development of a Salamander Embryo – Yale University Department of Anatomy (1920s)

November 10, 2017 at 4:08 pm / Evolution, Molecular Nature, Technical Notes, Video

Everyone of us started life from one single cell formed by the fusion of an egg and a sperm. That single cell gave rise to every structure in our bodies. How did that happen? Salamanders are known to be able to regenerate limbs while frogs and lizards cannot. How and why? The time lapsed footage of salamander embryos developing from single fertilized eggs forms the basis of our morphological understanding of animal development. The footage recorded by Yale University researchers […]
