RNA Interference (RNAi) – Nature Reviews Genetics

June 25, 2014 at 10:06 am / Evolution, Molecular Nature, Video

Welcome to another post of Molecular Nature series highlighting a gene silencing mechanism known as RNA interference. The discovery was made by Craig Mello and Andrew Fire who shared 2006 Nobel Prize in Physiology and Medicine. Please keep in mind that this video is quite advanced in content and assumes the viewers know about basic molecular biological concepts such as the Central Dogma of Biology. RNA interference (RNAi) is a process used by wide range of organisms to regulate the […]

Last Remaining Asian Lions – Pride – Roshan Patel (2013)

May 22, 2014 at 11:14 pm / Natural history, Video, Wildlife Documentaries

Big cats are under threat in every part of the world. Asiatic lions (Panthera leo persica) once roamed all the way up to Europe. Now only 50 left in the wild in Gujarat, India. Pride looks into how rural communities started working with the government to create a protected habitat for the highly endangered Asiatic lions. The documentary was produced by Roshan Patel as a project for masters degree program in the School of Film and Photography of Montana State […]

The Hidden Life of the Cell – BBC (2012)

May 16, 2014 at 11:33 pm / BBC documentaries, Evolution, Human Nature, Molecular Nature, Video

Ebola virus is threatening to spread out of Africa. Zika virus is evolving and circulating in more than 50 countries. At this stage we must inform ourselves and others about viruses. The Hidden Life of the Cell does just that by illustrating a real scenario of adenovirus infection and while doing that introduces major cellular components. The documentary is quite successful in explaining the biology behind events. However, you might also want to see Inner Life of Cell and the […]

Inner Life of the Cell – David Bolinsky (2006)

May 15, 2014 at 10:52 pm / Molecular Nature, Video

The Inner Life of the Cell is a 3D computer graphics animation by David Bolinsky, former lead medical illustrator at Yale. He collaborated with lead animator John Liebler, and Mike Astrachan at XVIVO for this production. It illustrates the molecular interactions that occur when a white blood cell (Leukocyte) in the blood vessels of the human body is triggered by inflammation. This is also called leukocyte extravasation. It begins with a white blood cell rolling along the inner surface of […]

The Making of the Fittest: Evolving Switches, Evolving Bodies – HHMI – Sean Carrol (2012)

April 22, 2014 at 11:07 am / Evolution, Molecular Nature, Natural history, Video

Evolving Switches, Evolving Bodies is one of the series of educational videos called The Making of the Fittest by Sean Carroll for communicating biological evolution to public with the support of Howard Hughs Medical Institute – HHMI. Evolution is thought to be acting very slow usually over millions of years. However, it can happen suprisingly quick. In this documentary, we look at a fish that evolved to change its body between two states reversibly multiple times over a few thousands […]

The Making of the Fittest: Birth and Death of Genes – HHMI – Sean Carrol (2011)

April 21, 2014 at 3:11 pm / Ecological Documentaries, Evolution, Molecular Nature, Natural history, Video

A fish caught known as Crocodile fish or icefish in Antarctic waters by the Norwegian expedition in 1927 tells us another fascinating story on evolution of life. Birth and Death of Genes is one of the four educational videos Sean Carroll has produced for communicating biological evolution to public with the support of HHMI. These fishes (called Nothothenoids) are unique for they are the only vertebrates in the world that lack the oxygen-binding protein hemoglobin, which gives blood its red […]

Appetite for Extinction – Invasive Lionfish of the Bermuda – Robert S. Zuill (2013)

April 10, 2014 at 4:12 pm / Ecological Documentaries, Video

Lionfish are popular aquarium fish native to the Indo-Pacific region. The lionfish invasion in the western Atlantic began in the mid 1980s off the southern coast of Florida, USA. From Florida, lionfish have spread in all possible directions. By 2000, individuals had been sighted off the coast of North Carolina and Bermuda. First lionfish were reported from the Bahamas in 2004, where they quickly dispersed throughout the archipelago by 2007. The range of lionfish has increased further southward. Lionfish now […]

International Space Station – ESA (2012)

March 2, 2014 at 11:43 pm / Human Nature, Video

As part of the Human Nature series Nature Documentaries would like to draw your attention to the International Space Station. At 350 km (240 miles) above the earth International Space Station is the farthest outpost of humanity. We humans like to experiment on ourselves. That is how we spread all over the world and even reached most isolated islands in the middle of the Pacific ocean. As we discovered new places We invented new ways to live and reproduce. One […]

Pitcher Plants of Palawan – Stewart McPherson (2010)

February 26, 2014 at 3:18 pm / Ecological Documentaries, Natural history, Video, Wildlife Documentaries

The naturalist and explorer Stewart McPherson sets out to discover new species of pitcher plants on the Island of Palawan in the Philippines. Carnivorous plants have the most impressive adaptations that help them survive comfortably in low-nutrient environments. Most plants absorb nutrients through their root but carnivorous plants trap and digest various invertebrates to get nutrients. Even small frogs and mammals can become prey. McPherson previously discovered 5 new species of pitcher plants and photographed one that has trapped a […]

First Life with David Attenborough – Arrival BBC (2010)

February 15, 2014 at 10:32 pm / BBC documentaries, Evolution, Video

BBC’s First Life is a marvelous encapsulation of life’s evolution in two episodes. Episode one “Arrival” covers major events until the Cambrian Explosion. If you are here because you want to know about the origins of life you may be slightly frustrated. The episode will briefly mention underwater hydrothermal vents as possible locations that life may have started and will mention about stromatolites which appeared in geological history around 3.5 billion years ago and that’s it. It will not talk […]

Crows Mobbing a Bald Eagle – Kevin Ebi & Jennifer Owen (2011)

February 10, 2014 at 1:28 pm / Natural history, Short Observations, Video, Wildlife Documentaries

Many of us might have witnessed this pre-emptive behavior but never had the chance or reflexes to record it. Kevin Ebi and Jennifer Owen successfully documented the predator deterrence behavior of crows. This observation is a part of a much larger project. Kevin has spent three nesting seasons with a pair of bald eagles nesting in Heritage Park, Kirkland, Washington and wrote a book. According to his account the video is from June 12, 2011. Two cameras were used to […]

Catapulting Tentacles in a Sticky Carnivorous Plant – Siegfried R. H. Hartmeyer (2012)

February 8, 2014 at 9:37 pm / Short Observations, Video

Drosera glanduligera is a sundew (Droseraceae) from southwestern Australia growing in all kinds of soils. It supplements its diet with arthropods. It has evolved a sophisticated catapult mechanism to capture prey. The hairs found on the surfaces plants are called trichomes. Each trichome is a projection made out of one single cell. Trichomes are quite versatile structures. They can be tweaked to repel or capture water, reflect away or concentrate (focus) light on the photosynthetic cells. They can accumulate irritating […]

Earth from Space – NOVA (PBS) 2013

January 30, 2014 at 3:57 pm / Global Patterns, PBS Nature, Video

Earth from Space is an excellent overview of global cycles. NASA visualizations based on Earth Observation System (EOS) show us how massive scale interactions among ocean, land, atmosphere and life determine the climate all driven by solar energy. The instruments in EOS satellites are so accurate that even the effects of most unexpected and sudden events like the Chelyabinsk Airburst Event of 2013 can be tracked and measured as it is happening in real time. These instant high resolution measurements […]
