Acid Test – Natural Resources Defense Council (2009)

April 8, 2017 at 5:05 pm / Ecological Documentaries, Global Patterns, Video

Since the beginning of the industrial revolution a quarter of the carbon that has been released into the atmosphere was absorbed by the oceans. As a result the acidity of the oceans has increased by %30. Increasing acidity makes it corrosive dissolving the calcium shells of marine organisms. Among them are planktons, corals and pteropods which form the base of the food web. Carbon dioxide dissolves higher quantities in cold water, therefore first biological signs of acidification is observed closer […]

The Central Dogma of Biology – Kazufumi Watanabe (2008)

March 18, 2017 at 1:45 am / Evolution, Molecular Nature, Video

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)

March 12, 2017 at 1:23 pm / Technical Notes, Video

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 […]

A Tour of the Cryosphere – NASA Goddard Space Flight Center (2009)

February 19, 2017 at 10:26 pm / Global Patterns, Video

The cryosphere covers parts of the Earth’s surface where water is found in the form of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. Ice and snow exist close to their melting point. Fluctuations in surface temperatures of our planet leads to frequent state changes in water from solid to liquid and back. Using satellite observations scientists monitor such changes in the global and regional climate. The Earth’s cryosphere shrink and expand on a yearly basis. Antarctica The animation […]

Geological History of the Continents/Paleomap Project – Christopher Scotese (2015)

January 5, 2017 at 9:28 pm / Evolution, Global Patterns, Video

Geology and biological evolution of life are inseparable. More than half of the minerals now incorporated into the upper crust of our planet were produced by living organisms. The movement of continental plates has played a fundamental role in the recycling of mineral resources by the biosphere. Scientists now predict that tectonic activity may have been one of the prerequisites for the origin of life. The acceptance of continental drift by the scientific community and how it affected Earth’s history […]
