  Structure of a Spliceosome: Molecular Framework for Understanding Pre-mRNA Splicing – Beauty of Science

  May 2, 2020 at 8:48 am / Molecular Nature

  One Gene-One Peptide Hypothesis was a bold statement proposed by Edward Tatum and George Beadle in 1941 heralding the nascent field of molecular genetics. The proposal was long before we knew anything about the nature and structure of the DNA. It was rather vague how a gene encoded a protein. The Central Dogma of biology was coined by Francis Crick in late 1950s but the intermediate molecule known as the messenger RNA was identified (?) in 1960 by Arthur Pardee, […]

  ATP Synthase in Action – HarvardX / BioVisions

  April 27, 2020 at 3:09 pm / Molecular Nature, Video

  ATP is a universal energy storing molecule in biological systems. How does life generate ATP from ADP? Similarly, how does life consume it on an industrial scale in membrane bound systems such as mitochondria and chloroplasts? ATP synthase (or ATPase depending on which catalytic direction you look at it) enzyme is a hugely interesting molecular structure. Yes it most certainly is a bi-directional turbine. It is one of the few rotatory molecular structures life has evolved such as the flagella […]

  Electron Transport Chain – HarvardX / BioVisions (2013)

  April 27, 2020 at 9:14 am / Evolution, Molecular Nature

  Understanding molecular nature of life is not easy without informative scientific visualizations. Distillation of this rich body of information generated over decades or even century long research into a visual medium can be key to grasp complexities of subcellular structures. Take the Central Dogma of biology for instance. The Central Dogma animation distills more than half a century of intense laboratory research that started with Rosalind Franklin and Raymond Gosling’s extraordinarily historic X-ray diffraction photograph in 1952. Photo 51 was […]

  Eye of the Pangolin – Pangolin.Africa (2019)

  April 2, 2020 at 11:21 am / Ecological Documentaries, Evolution, Natural history, Video, Wildlife Documentaries

  The etymological origin of the name pangolin comes from the Malay word pengguling. It means “one who rolls up”. The animal has at least eight species with a wide geographical distribution ranging from Africa to Indian subcontinent and southeast Asia including Malayan Archipelago and Indonesia. Unfortunately we know very little about this highly elusive animal and its existence is under threat. Scaly anteaters are quite unusual among mammals since their skin is covered by large and overlapping keratinized scales hugely […]

  Gear CDC’s Disease Detectives Use – Wired Magazine (2018)

  January 28, 2020 at 10:00 pm / Human Nature, Video

  Disease and pandemics are scary. As the world is shaking with the news of a new corona virus outbreak in China it is informative to take a look into gear used by “the disease detectives” ie. Center for Disease Control and Prevention. The movie Contagion (2011) has done a great job for educating public by depicting a rather probable scenario of a viral outbreak largely based on the SARS outbreak of 2003. The hugely successful BBC documentary The Hidden Life […]

  Snakes in a Cave – Nate Dappen & Neil Losin (2014)

  January 24, 2020 at 8:36 pm / Natural history, Short Observations, Video, Wildlife Documentaries

  As the world is shaking with the news of a new corona virus outbreak in China, researchers have quickly identified the potential source of 2019-nCoV based on the spike forming glycoprotein structure. Just like the hugely informative movie Contagion (2011) depicting a realistic scenario this new virus was a bizarre sounding recombinant. The corona virus SARS-CoV-2 appeared to be a recombinant of a bat and a snake virus. At first, you may naturally ask how could this weird merger have […]

  ORBIT – Seán Doran (2018)

  December 23, 2019 at 8:33 pm / Global Patterns

  ORBIT compiled by Seán Doran is a wonderfully poetic “out of the world” representation of global patterns based on observations from the International Space Station. The film leverages NASA’s Gateway to Astronaut Photography of Earth program. NatureDocumentaries.org always endorses the motto “Science can be beautiful and art can be informative”. The International Space Station experiences on average 16 sunrises in a typical 24 hour period. It circles the Earth in between 92-93 minutes. You can learn more about the travel […]

  In Nomine Terra Calens: In the Name of a Warming Earth – Lucy Jones (2019)

  October 9, 2019 at 2:33 pm / Global Patterns, Human Nature, Video

  Science can be beautiful. Art can be informative. The urgency of climate change is a pressing issue of our time. Scientists have done their job superbly demonstrating causes for why and how our planet is warming due to Human activities. They have done it by making long term measurements of atmospheric CO2 levels and deep drilling of polar ice cores. The scientific facts are all very clear indicating excessive fossil fuel use must end. However the message is clearly not […]

  The Making of Silent Running (1972) – Douglas Trumbull

  October 1, 2019 at 5:30 pm / Human Nature, Technical Notes, Video

  Silent Running is a landmark 1972 film directed by Douglas Trumbull. Over the years, it became a cult sci-fi classic and is seen as one of the most pivotal philosophical movies for environmental movement. Recall that Greenpeace was started in 1971 and the spirit of the times was chiming with anti-nuclear sentiment. Obliteration of humankind was indeed an apocalyptic possibility under Cold War. Rachel Carson’s hugely influential 1962 book Silent Spring which showed the global impact of the pesticide DDT […]

  Film Grammar – Khan Academy (2017)

  September 28, 2019 at 9:22 am / Human Nature, Technical Notes, Video

  This collaboration between Khan Academy and Pixar is a wonderful demonstration of building tool kits for self learning. Psychologists argue that an important cognitive function known as working memory is what made us into modern humans. As the highly inspirational illustrator Beatrix Potter put it, one cannot truly study anything without drawing it. Drawing is an effective working memory exercise that helps reinforce information by converting a short term memory into a long term one. That could be one reason […]
