Top 10 Amazing Biology Videos | Wired Science Cyborgs, stem cells, glowing mice, and hilarious music videos are great reasons to be excited about biology. Here are some of our favorite clips from the life sciences. 10. Immune Cell Chasing a BacteriumIt may look like the predecessor to Pac Man, but this vintage clip shows a neutrophil wending its way through a crowd of red blood cells to destroy its bacterial nemesis. 9. How High Speed Gene Sequencing Works Within the next few years, Helicos BioSciences may be able to read an entire human genome for under one thousand dollars. 8. 7. 6. 5. 4. 3. 2. 1. Last week, regenerative medicine researchers announced that they have grown a new windpipe for a woman who was crippled by tuberculosis. See Also:

Biology Biology 1A: General Biology (Spring 2010) Largest Living Thing | Mushroom in Oregon Home > Animal Kingdom > Animal Records > Largest Living Thing Largest Living Organism: Fungus Armillaria ostoyae A Fungus Among Us People have known about the "honey mushroom" for some time, but were not aware of how large and invasive this species of fungus could be. The fungus was investigated more closely by researchers when they realized that it was responsible for killing large groves of evergreen trees. When foresters cut into an infected tree they would find spreading white filaments, mycelia, which draw water and carbohydrates from the tree to feed the fungus. Humongous Fungus Until August of 2000 it was thought that the largest living organism was a fungus of the same species (Armillaria ostoyae) that covered 1,500 acres (600 hectares) found living in the state of Washington. To go into the forest where this giant makes its home you would not look at it and see a huge, looming mushroom. How is it possible for a single fungus to get so big?

Stellar by Ignacio Torres Beautifully executed animations by Texas photographer Ignacio Torres from his series Stellar. Via his website: This project began from the theory that humans are made of cosmic matter as a result of a stars death. These are just a selection of the series, click through to see the entire project. Cellular Respiration Demo using Gummy Bears - Exciting!! This is a very simple demonstration that makes an impact. It illustrates energy release that occurs quickly. In the demonstration, Mr. Carter (the other science teacher at my school) visually reinforces the necessity of cellular metabolism’s small-step oxidation of glucose instead of releasing it all at once. The materials you will need for this demonstration are as follows: Approximately 1 tablespoon of Potassium ChlorateLarge test tubeGummy bear (or any other gummy animal)Fume hood (or any system to allow for the fumes to escape without engulfing the room)Eye protection (Lab Goggles, etc) The solid should be heated until it melts, and then the gummy bear can be dropped in. The products of the reaction should be potassium chloride (white deposit near the mouth of the test tube) as well as varying amounts of soot or charred gummy bear if not all of it is used up in the reaction. This kind of “all at once” release of energy would be catastrophic in a living organism.

Make A Bee Waterer And Help Hydrate Our Pollinators A single bee tends to at least 2,000 flowers daily, with their tiny wings beating 10,000 times per minute, carrying pollen, and dramatically assisting our food supply. All that work makes the bees thirsty, especially on a hot day. Bees need access to safe water sources, they often risk drowning in birdbaths or being eaten at rivers and lakes among birds, fish, frogs and other wildlife. This is why they often fly around our clothes lines and may even land on us if we are in an outdoor pool on a hot day. Kim Flottum, editor of the Bee Culture magazine, writes in her book The Backyard Beekeeper: An Absolute Beginner’s Guide to Keeping Bees in Your Yard and Garden: “Water is used to dissolve crystallized honey, to dilute honey when producing larval food, for evaporation cooling during warm weather, and for a cool drink on a hot day.” “Bees know exactly where to return for the same water source. One solution to this problem is to add marbles or pebbles to a bowl or pan and then add water.

The 9 Epiphanies That Shifted My Perspective Forever By David Over the years I’ve learned dozens of little tricks and insights for making life more fulfilling. They’ve added up to a significant improvement in the ease and quality of my day-to-day life. The world now seems to be a completely different one than the one I lived in about ten years ago, when I started looking into the mechanics of quality of life. Maybe you’ve had some of the same insights. 1. The first time I heard somebody say that, I didn’t like the sound of it one bit. I see quite clearly now that life is nothing but passing experiences, and my thoughts are just one more category of things I experience. If you can observe your thoughts just like you can observe other objects, who’sdoing the observing? 2. Of course! 3. I now consider this truth to be Happiness 101, but it’s amazing how tempting it still is to grasp at control of every circumstance to try to make sure I get exactly what I want. 4. 5. Yikes. 6. 7. 8. Believing something is not an accomplishment. 9.
