  Learning to Live on the Moon – PBS

  May 17, 2016 at 2:04 pm / Ecological Documentaries, Human Nature, Nova Documentaries, PBS Nature, Video

  Energy flows, nutrients cycle. This is how we can define working principles of an ecosystem in a nutshell. Our planet has a very complex land-air-water interaction and we are only beginning to understand the behavior of these systems by simplifying them in enclosed systems such as Landscape Evolution Laboratory (LEO). Due to its proximity, the Moon appears to be the most convenient celestial body to colonize. The Moon is so close that it can even occasionally get shielded by the […]

  Understanding Our Moon – NASA/SVS

  May 17, 2016 at 2:02 pm / Video

  The Moon has been a very influential body on life on Earth. Some argue that having a satellite like the Moon is a prerequisite for life in other planets. The Moon has a stabilizing effect on rotation axis of our planet. Without it, the axis would wobble more erratically making ice ages and inter-glacial warming periods more extreme and sudden. Understanding our Moon will help understand evolutionary history of our planet. After all, both bodies have started forming from the […]

  Decoding the Chemical Language of Nature – Jing-Ke Weng | TEDxBeaconStreet (2015)

  May 6, 2016 at 9:17 pm / Evolution, Molecular Nature, Natural history

  Chemical diversity in nature is bewildering. Repertoire of chemicals in plants is especially rich. A great majority (almost all) of the single-compound drugs have been discovered in plants: salicylic acid (Aspirin), artemisinin (anti-malarial), thebaine (analgesic derived from opium) are just a quick few to spell out. All these chemicals are products of specialized secondary metabolic pathways in plants. Chemical compounds forming specialized metabolites protect plants against various abiotic stresses and mediate an array of interspecies interactions, ranging from seduction of […]

  Conserving Colombia’s Cotton-Top Tamarin – Federico Pardo (2011)

  April 21, 2016 at 11:20 am / Ecological Documentaries, Natural history, Video, Wildlife Documentaries

  About the size of a squirrel, the cotton-top tamarin (Saguinus oedipus) is a New World primate. It has a characteristic shock of white hair on it’s head. Males and females do not vary in size (not sexually dimorphic). The cotton-top tamarin was declared endangered in 1973 following the exportation of 20,000-40,000 tamarins to the United States for use in biomedical research. Cotton-top tamarins were found to spontaneously develop colorectal cancer and for this reason served as an ideal model for […]

  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 […]

  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 […]
