Attenborough and the Giant Dinosaur – BBC (2016)

April 10, 2016 at 10:56 am / BBC documentaries, Evolution, Natural history

On February 19th 2016, a replica of the massive Titanosaurus dinosaur (Patagotitan mayorum) discovered in Argentinian Patagonia was unveiled at the American Museum of Natural History in New York. It is continuing to send strong waves of excitement to all natural history enthusiasts worldwide. Based on accurate dating of the volcanic ash surrounding the fossil we now know that the animal lived 100.6 million years ago during the Cretaceous. It belongs to the Sauropod group and yet is the largest […]

Giant Ichneumon Wasp (Megarhyssa macrurus) Ovipositing

April 3, 2016 at 1:49 pm / Natural history, NatureDocumentaries.org, Short Observations, Video

Giant Ichneumon wasp (Megaryssa macrurus, Linneaus 1771) ovipositing. 10th of August 2013, Georgia State Botanical Garden, Athens, GA. 3:47 pm. This observation has been registered in iNaturalist.org with ID# 418639. Oviposition marks the beginning of the life cycle of all insects including parasitoid wasps. Females of Megarryhssa macrurus (Hymenoptera: Ichneumonidae) are specialized to lay their eggs in the burrows of wood eating Pigeon Tremex Horntail (Tremex columba) larvae between June and September. Only one egg is deposited per host larva […]

What’s Really Warming Up Our Planet? NASA – SVS (2015)

April 1, 2016 at 2:09 pm / Global Patterns, Human Nature, Video

NASA’s Scientific Visualization Studio (SVS) produced yet another visual to show how industrial and natural factors have been contributing to the global warming. These factors are wobbling of Earth’s axis, solar activity, volcanoes, land use, ozone pollution, aerosol pollution, greenhouse gases and their combined effects. The case is rather clear. Combined effects of man made factors follow the trajectory of warming closely. Since 1880 our planet warmed 1.4 degrees Fahrenheit and continues to increase. The atmospheric carbon concentration has passed […]

The Day The Mesozoic Died HHMI – Sean B. Carroll (2012)

March 30, 2016 at 3:09 pm / Evolution, Global Patterns, Video

This is one of the four educational video series by Sean B. Carroll produced for communicating evolution to public with the support of HHMI. Today we know the cause of the disappearance of the dinosaurs at the end of the Cretaceous period. This knowledge was produced by the meticulous coordinated work of many scientists. The Day The Mesozoic Died focuses on how scientists do the detective work using the scientific method. The discovery that an asteroid struck the Earth 66 […]

How Does the Purple Bacteria Photosynthesize? Beckman Institute-UIUC (2015)

March 28, 2016 at 11:03 am / Evolution, Molecular Nature, Video

Imagine a time when our young Earth was spinning much faster and days were only 8 hours! Our sun was much cooler and less bright than today. There was no oxygen in the atmosphere. Those were the conditions when first photosynthetic organisms with purple pigments evolved in liquid environments. In this animation we see one such ancestral form of early anoxic photosynthesis taking place in the purple bacteria Rhodobacter sphaeroides in which oxygen is not produced. Life evolved into oxygen […]

The Science of Camera Sensors – FimmakerIQ (2015)

March 24, 2016 at 11:17 pm / Technical Notes, Video

Camera technology has come a long way since the legendary Akeley gyroscope camera that made filming of truly historic documentary films such as Nanook of the North (1922) and Grass (1922). Now everything digital, an overview of the modern camera sensors is useful for naturalists. This lecture by FilmmakerIQ is a part of the Technical Notes series by Nature Documentaries aiming to compile useful technical, theoretical and practical knowledge for documentary filmmakers. The episode illustrates the electronic working principles of […]

The History and Science of Lenses – FilmmakerIQ (2015)

March 24, 2016 at 11:16 pm / Technical Notes, Video

Glass has been a truly transformational material in Human history. Among many other remarkable things glass helped us understand and control properties of light. From photocopying machines to fiber optic cables glass revolutionized our lives. Gutenberg’s printing machine was a turning point with an unintended consequence. Printing created a huge demand for spectacles and glasswork craftsmanship in Europe literally exploded. Craftsmanship that built spectacles lead to building of more specialized optical instruments including microscopes, telescopes and eventually cameras. For all […]

Depth of Field and Lens Equivalents – FilmmakerIQ (2016)

March 24, 2016 at 11:14 pm / Technical Notes, Video

How does one achieve a sharp and clear image? What is depth of field? What is depth of focus? What affects their shallowness? This episode from FilmmakerIQ nicely explains the theory behind using the physics of light. Before starting the lecture you should have some basic understanding of the camera lenses such as the aperture. This is a part of the Technical Notes series of Nature Documentaries aiming to compile useful technical, theoretical and practical knowledge for documentary filmmakers. The […]

The History of Frame Rate for Film – FilmmakerIQ (2015)

March 24, 2016 at 11:11 pm / Technical Notes, Video

This is a great breakdown of seemingly arbitrary and highly variable frame rates we experience today. Until the incorporation of sound which arrived as a superbly egalitarian/standardizing factor into the film, the frame rates were rather floppy. This lecture by FilmmakerIQ is a part of the Technical Notes series by Nature Documentaries aiming to compile useful technical, theoretical and practical knowledge for documentary filmmakers. The compact episode introduces the historical transitions from hand-cranked cinematographic cameras into television and later to […]

The Properties of Camera Lenses – FilmmakerIQ (2015)

March 24, 2016 at 11:08 pm / Technical Notes, Video

The Technical Notes series of Nature Documentaries aims to compile useful technical, theoretical and practical knowledge for documentary filmmakers. In this lecture from the FilmmakerIQ you will be exposed to some basic properties of the camera lenses such as the focal length and the aperture. The episode is also a good segway into sensor technology which also gets covered in more detail in another episode. The episode gives a quick primer on focal length, field of view, diffraction theory and […]

Visitors of Jerusalem Thorn (Paliurus spina-christi)

March 18, 2016 at 1:07 pm / Ecological Documentaries, Natural history, NatureDocumentaries.org, Short Observations, Video

The Jerusalem Thorn (Paliurus spina-christi) is a native evergreen bush of the Mediterranean basin belonging to the Buckthorn family (Rhamnaceae). As you might have already guessed from its scientific name, this is the plant depicted as a torture device (the crown of thorns) on prophet Jesus Christ’s head. The genus Paliurus is quite recognizable by its orbicular-winged fruit. The fossil record for the genus is widespread in the Northern Hemisphere and goes back to the middle Eocene epoch (~34 million […]

The Carnivorous Venus Flytrap Plants Can Count – Jennifer Böhm (2016)

February 27, 2016 at 3:09 pm / Evolution, Natural history, Video

Researchers at the University of Würzburg, in Germany have shown for the first time that carnivorous Venus flytrap plants (Dionaea muscipula) have the ability to track time between two stimuli 20 seconds apart precisely. This time keeping ability is a remarkable evolutionary adaptation that minimizes false signals that may lead to unnecessary trap closure. Nature is full of random unexpected events and Venus flytrap survival depends on a reliable trigger mechanism for its trap closure. A sensitive trap closing due […]
