Short Films “Film is a powerful way to tell stories. … The right story, told well, can be engaging, informative, and memorable.” —Sean B. Carroll Simulador enfoque camaras digitales Lighting Lighting is the single biggest determinant of how your camera needs to be set. With only a few exceptions, you can never have too much light. Use this slider to experiment with different indoor and outdoor lighting conditions. Distance

Chlorophyll can help prevent cancer A recent study at Oregon State University found that the chlorophyll in green vegetables offers protection against cancer when tested against the modest carcinogen exposure levels most likely to be found in the environment. However, chlorophyll actually increases the number of tumors at very high carcinogen exposure levels. Beyond confirming the value of chlorophyll, the research raises serious questions about whether traditional lab studies done with mice and high levels of toxic exposure are providing accurate answers to what is a real health risk, what isn't, and what dietary or pharmaceutical approaches are useful. The findings, published in the journal Food and Chemical Toxicology, were done using 12,360 rainbow trout as laboratory models, instead of more common laboratory mice. Rodent studies are much more expensive, forcing the use of fewer specimens and higher carcinogen exposures. This work was supported by the National Institutes of Health.

Science Homework Help - Science Videos Study Your Way Easy Help. Fun Teachers. Expert teachers who know their stuff bring personality & fun to every video. Key Concepts explained. The Virtual Lab Series BioInteractive’s virtual labs have won several awards, including top honors in the Pirelli INTERNETional Award competition, which recognizes the best multimedia products designed to use the Internet to educate about science and technology. Designed in close consultation with educators and scientists, these virtual labs are fully interactive biomedical laboratory simulations and provide students with skills and techniques used in scientific research. BioInteractive’s series of virtual labs allows students to examine heart patients, analyze DNA sequences, probe the nervous system of a leech, use human antibodies to diagnose disease, and measure physical traits of stickleback fish and anole lizards to examine key concepts in evolution. Each lab provides an interactive environment in which students perform experiments and collect their data, and answer questions to assess their understanding.

Cnidaria From New World Encyclopedia Cnidaria (pronounced with a silent c) is a phylum containing some 11,000 species of relatively simple invertebrate animals found exclusively in aquatic, mostly marine, environments. Cniderians include corals, sea anemones, jellyfish, sea pens, sea pansies, and sea wasps, and tiny freshwater hydra. The name of the phylum comes from cnidocytes, which are specialized cells that carry stinging organelles. Life boils down to five 'rules' ... or so says the Madingley Model It may sound overly simple, but just five processes can define us as animals: eating, metabolism, reproduction, dispersal and death. They might not seem like much, but, thanks to a mathematical model from scientists at Microsoft Research, we know that these five processes are the key to all ecosystems. It’s called the Madingley Model, and is the first time scientists have simulated ecosystems across the globe using a single set of biological rules.

Ed Tech Start Ups Group News The following are some good resources to help students explore the human body through interactive imaging, games, exercises and more. Build-a Body: This is a great website that allows students to build the human body using interactive elements system by system. Each system has descriptions and provides some facts about diseases. Students will only drag and drop the parts of body such as bones, organs,..ect. BioDigital Human This is a great resource for anatomy. It lets users view the human body in 3D, hide or remove layers, create custom views and many more.

Darwin 2.0: Scientists shed new light on how species diverge Birds that are related, such as Darwin's finches, but that vary in beak size and behavior specially evolved to their habitat are examples of a process called speciation. It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent study shows that speciation occurred much later than these dramatic geographical changes. Researchers from LSU's Museum of Natural Science have found that time and a species' ability to move play greater parts in the process of speciation. This research was published today in the print edition of Nature.

Over time, these ideas and techniques can be revised or replaced in the light of new research. Most changes to key science ideas are only accepted gradually, tested through research by many people.
