  • Perpetual Ocean from NASA

    Perpetual Ocean from NASA

    Understanding large-scale global climate and local weather patterns is life saving. Majority of our planet is covered by oceans therefore understanding ocean dynamics is key for making climatic forecasts. Here you can watch four interrelated animations produced by NASA’s Scientific Visualization Studio in a single video. All animations are based on simulations of high resolution satellite data on an impressively realistic General Circulation Model (GCMs) that NASA uses called ECCO2 (Estimating the Circulation and Climate of the Ocean Phase II).

  • Annotated Features of Moon Surface – Kaguya/JAXA

    Annotated Features of Moon Surface – Kaguya/JAXA

    Some astrobiologists consider that having a satellite as big as The Moon could be one of the prerequisites of life on a planet. Satellites with sufficient mass can exert a stabilizing effect on the rotation axis of its planet preventing erratic wobbles like a top loosing its speed. In fact, our Earth experiences such wobbles known as the Milankovich Cycles but thanks to our moon the effects are dampened. 2019 marked the 50th anniversary of the Apollo 11 Moon landing […]

  • Wallace in Borneo – Bill Bailey’s Jungle Hero – BBC (2013)

    Wallace in Borneo – Bill Bailey’s Jungle Hero – BBC (2013)

    The theory of evolution was co-discovered independently by two biologists that lived within the same time period. Darwin and Wallace were well known in their time but Wallace’s name gradually has been overshadowed by Darwin. Today we rarely (almost never) hear the name Alfred Russell Wallace. In the past there have been a few documentaries making a rare attempt to focus on the biography of this very influential biologist including an episode in Jacob Bronowski’s 1973 The Ascent of Man […]

  • An Interactive Exhibit – “The Legacy of a Lifetime of Collecting: The Carl & Marian Rettenmeyer Story”

    An Interactive Exhibit – “The Legacy of a Lifetime of Collecting: The Carl & Marian Rettenmeyer Story”

    The interactive exhibit “The Legacy of a Lifetime of Collecting: The Carl & Marian Rettenmeyer Story,” was inspired by a fascinating collection of army ants and their hundreds of closely associated organisms, or “guests.” The specimens collected over the course of 50 years of fieldwork in South and Central America by the late Carl and Marian Rettenmeyer. Filmed entirely on location at La Selva Biological Field Station in Costa Rica Rettenmeyers produced a two part documentary series on this ecologically […]

  • Climate Change – The Facts / David Attenborough – BBC (2019)

    Climate Change – The Facts / David Attenborough – BBC (2019)

    This documentary has a very urgent message (so urgent that I don’t even have time to write up an accompanying text about it!). It is a call to arms. Climate change from global warming due to Human activities is now a well-established fact. Global atmospheric carbon dioxide level is now more than 410 ppm. In fact, you can check the most up to date atmospheric CO2 reading from Hawaii yourself. We have less than a decade to curb our emissions […]

  • A Diverse Tropical Forest Canopy and Crown Shyness – Dimitar Karanikolov (2019)

    A Diverse Tropical Forest Canopy and Crown Shyness – Dimitar Karanikolov (2019)

    This is a wonderfully poetic and at the same time quite informative piece of short observation captured by the photographer Dimitar Karanikolov. The video successfully demonstrates a botanical phenomenon known as “crown shyness” by providing a nicely stabilized vertical view of canopy trees swaying by the wind in Tulum Mexico. Tree canopies are some of the most diverse sections in tropical forest. The exact mechanism of crown shyness is still not resolved but there are quite a few convincing hypotheses. […]

  • How Enzymes Work? – PDB/RCSB

    How Enzymes Work? – PDB/RCSB

    Enzymes are a catalytic subgroup of proteins formed as end products of the Central Dogma of biology. They are essential for cellular functioning. Here in this Protein Data Bank (PDB) video the enzymes constituting the hugely important metabolic pathway –the citric acid cycle– that connects carbohydrate, fat and protein metabolism are briefly visualized. Subsequently, the enzyme aconitase (aconitate hydratase; EC 4.2.1.3) in this hugely important metabolic pathway is highlighted as an example. The steps taking place in the active site […]

  • What is a Protein? – Protein Data Bank/RCSB

    What is a Protein? – Protein Data Bank/RCSB

    Proteins are end products of the Central Dogma of biology. They are essential for cellular structure and function. Proteins have dizzyingly diverse structures. Since the invention of X-ray chrystallography by the Australian physicist William Lawrence Bragg structures of many complex molecules have been resolved including proteins. Solved structures of proteins are deposited in the Protein Data Bank (PDB), a free and curated structural data resource for thousands of biological molecules. These structures are stored in the form of Cartesian coordinates […]

  • Hurricane-induced Selection on the Morphology of an Island Lizard – Nature (2018)

    Hurricane-induced Selection on the Morphology of an Island Lizard – Nature (2018)

    Hurricanes are catastrophically destructive and can have long-lasting effects on ecological systems. For instance, the Atlantic hurricane season of 2005 was a particularly strong one with record breaking 27 named storms. Mass mortality observed after hurricanes may be a force of natural selection. The hypothesis that destructive events such as hurricanes could drive natural selection has been controversial. In order to test this, scientists surveyed a common, small-bodied lizard (Anolis scriptus) that lives throughout the Turks and Caicos archipelago before […]

  • Ritualized Aggression in Humans – Haka / Ben Hall (2011)

    Ritualized Aggression in Humans – Haka / Ben Hall (2011)

    Ritualization of aggression is a beneficial strategy to tone down conflicts and avoid serious damaging consequences. Most of the time fighting is risky, wasteful and destructive. Ritualized aggression can resolve conflicts without resorting to actual violence. Besides humans ants, dogs and crayfish are known to engage in mock battles. Analytical tools used by evolutionary biologists have been very successful in explaining emergence of complex human and non-human behavior. Ritualized aggression is among them. The workers of the Malaysian giant forest […]

  • An Introduction to Zebrafish Brain

    An Introduction to Zebrafish Brain

    What is consciousness? How do we learn complex coordinated movements like riding a bicycle and never forget afterwards? How does your brain know where your body ends and bicycle starts? The humble Zebrafish has all the clues to these questions and more. Systems simple enough to understand and complex enough to make generalizations always attracted scientists. The 80,000-neurons in the brain of the developing the zebrafish embryos provides one of those ideal systems to understand vertebrate brain evolution and function. […]

  • Nice Guys Finish First – Richard Dawkins (1987)

    Nice Guys Finish First – Richard Dawkins (1987)

    In this BBC documentary Richard Dawkins explores the evolution of cooperation. The problem has been discussed intensely since Darwin’s time and is still being investigated scientifically. Cooperative species are quite successful but rare. Social insects (ants, wasps, bees and termites) make up only 3 percent of animal diversity yet they may constitute up to 50 percent of the total animal biomass in land habitats. Among 43,678 known species of spiders cooperative behavior evolved in only a few. How could a […]

  • A Virtual Tour of a Cell – XVIVO Scientific Animation (2018)

    A Virtual Tour of a Cell – XVIVO Scientific Animation (2018)

    The Cellscape is one of the many fascinating scientific visualizations created by XVIVO Scientific Animation Studio. The project was supported by Google Making and Science Team. The creators did a wonderful job in introducing us to the major parts of the cell visible to a viewer in the cytoplasm in a virtual environment. Conjuring the physico-chemical structures such as proteins and enzymes inside a cell is a rather difficult thing to do. The textbooks and diagrams, don’t do a justice […]

  • An Annotated Animation of Zebrafish Embryo Development – Edwin Mutuma Murungi (2017)

    An Annotated Animation of Zebrafish Embryo Development – Edwin Mutuma Murungi (2017)

    Evolutionarily speaking all of us are tetrapods and contain a fish inside! Take the retention of embryonic gill arches for example, still observed in quite a few people. Preaurucular pit is the scientific term for this ancestral structure. Its presence in Humans reflects the “evo-devo” aspect of our shared biological heritage with all vertebrates living on earth. Here, animated by Edwin Mutuma Murungi, the annotated animation of zebrafish embryo development produced by Norwegian University of Life Sciences – NMBU Learning […]
