New Discovery: NASA Study Proves Carbon Dioxide Cools Atmosphere A recent NASA report throws the space agency into conflict with its climatologists after new NASA measurements prove that carbon dioxide acts as a coolant in Earth's atmosphere. NASA's Langley Research Center has collated data proving that “greenhouse gases” actually block up to 95 percent of harmful solar rays from reaching our planet, thus reducing the heating impact of the sun. The data was collected by Sounding of the Atmosphere using Broadband Emission Radiometry, (or SABER). SABER monitors infrared emissions from Earth’s upper atmosphere, in particular from carbon dioxide (CO2) and nitric oxide (NO), two substances thought to be playing a key role in the energy balance of air above our planet’s surface. The shock revelation starkly contradicts the core proposition of the so-called greenhouse gas theory which claims that more CO2 means more warming for our planet. As NASA's SABER team at Langley admits: As the SABER research report states:  Brooks, C.E.P. (1951).

What is A Planet? What is A Planet? Description What is a planet? One such celestial object is Pluto, which became the 9th planet in 1930 to much controversy. Much like other sciences, such as Biology, where one may discover a new species, classification is a common and needed process which groups like objects for purposes of comparison and further study. Using 3D animation, this DVD was created to better illustrate the history behind the discussion defining “What is a Planet?” So come travel with us as we drive along the “Kuiper Belt highway” at 100 mph to explore the far reaches of our solar system and discover how vast our corner of the galaxy really is.

Beautiful physics: Tying knots in light New research published today seeks to push the discovery that light can be tied in knots to the next level. Dr Anton Desyatnikov from the Nonlinear Physics Centre at The Australian National University is part of an international team of scientists who are designing knots in light, with potential applications in advanced modern optics, laser beams and even quantum computing. Using concepts from mathematics and physics the model Dr Desyatnikov and his colleagues have explored creates optical vortices with dark cores in a bright laser beam, that can then tangle and form links and knots. "Apart from their curiosity value, what's really interesting and useful about these knots of darkness is that they show you what the power flow is doing," Dr Desyatnikov said. "It is part of the incredible progress science is making in the field of optics, we're beginning to do things with light that would have once seemed impossible." "However unlike electrical cables which love to form knots, light doesn't.
13 natural remedies for the ant invasion Little tiny ants have been spotted in our new home, and many people are suffering the same fate across the country. As much as I love spring, I don't like bugs — especially bugs that can infest a house. Last week I asked for some advice in how to deal with ants naturally as I didn't have time to research it myself since I just moved this weekend. Some of these measures are deterrents. 1. Teresa: We just spray around the openings with pure lemon juice … and it always works for us … something about the acid messes up their sense of tracking… 2. Shayla: We use ground cinnamon around where there are coming it. Peggy: We spray cinnamon essential oil all around the doors, windowsills, floors, etc. keeps them from coming in. Letia: Another vote for ground cinnamon. Jean: Cinnamon and cloves. Patricia: We also use cinnamon oil. 3. Heather: My mother-in-law has success with peppermint essential oil around windows and doors (any entries). Julie: Dr. 4. 5. 6. 7. Natalie: Oh! 8. 9. 10. 11. 12. 13.
How Big is the Solar System? Copyright 1989 by Guy Ottewell Universal Workshop PO Box 102 Raynham, MA 02767-0102 Toll Free: 800-533-5083 Fax: 508-967-2702 Email: email@example.com This is a classic exercise for visualizing just how BIG our Solar System really is. Both the relative size and spacing of the planets are demonstrated in this outdoor exercise, using a mere peppercorn to represent the size of the Earth. Introduction Can you picture the dimensions of the solar system? Probably not, for they are of an order so amazing that it is difficult either to realize or to show them. You may have seen a diagram of the Sun and planets, in a book. The fact is that the planets are mighty small and the distances between them are almost ridiculously large. The following exercise could be called a Model, a Walk or a Happening. There is one other party that may profitably take the planet-walk, and that is yourself, alone. First, collect the objects you need. This peppercorn is the Earth we live on. Follow-up
Live Wires Today’s information age rests on a basic understanding of how electrons move. The remarkable success of computers, cell phones, and other devices, such as solar cells, depends on our ability to mediate the flow of electrons through the semiconductors and microchips that control the function of these machines and give them their intelligence. But the importance of electron flow is by no means limited to these man-made systems; electron transfer is also central to energy storage and conversion in living cells. Organisms depend on the flow of electrons for key energy-generating cellular processes. Unfortunately, in contrast to our detailed knowledge of the electron flow in popular solid-state electronics, our understanding of biological electron transport remains limited, especially when the distances traveled far exceed the length of a cell. So how do they do it? Rock breathers Scientists discovered the first metal-reducing bacteria, Shewanella and Geobacter, in the late 1980s. Mohamed Y.
Top 10 air-purifying houseplants Most people spend a majority of their time indoors in increasingly well-sealed buildings surrounded by paints and other synthetic materials which off-gas noxious chemicals. These conditions are related to increasing incidences of asthma, allergies and cancer. Indeed, indoor air quality can be much more polluted than outdoor air, up to tenfold. When “sick building syndrome” was first becoming recognized as a growing problem, NASA conducted a study of various houseplants and their effectiveness at filtering out hazardous chemicals from the air. Their findings? Many of the plants were highly effective at removing hazardous chemicals from the air. The following are the top 10 indoor plants, as rated for ease of maintenance and effectiveness at purifying the air, summarized from NASA's studies. 1. The best performer at removing airborne toxins, it also releases moisture into the air to regulate humidity, and is attractive to look at. 2. 3. 4. 5. 6. English ivy grows well in hanging baskets.
Gummy Bear Science My kids had a great time experimenting with gummy bears! We used the "Black Forest" brand of Gummy Bears - results may vary depending on the brand you use. Here is what happened with the Black Forest gummy bears: Gummy bears do some interesting things when put into different liquids. Here's what our overnight results look like: We recorded length & mass before & after the experiment. My students completed a lab report with 2 charts and 2 graphs for data analysis, here are 3 of the 6 pages: All of the gummy bears GREW due to osmosis. You can get the complete lab worksheets for free at my Teachers Pay Teachers store by clicking here. We're still in school here - anyone else? Physicists twist water into knots More than a century after the idea was first floated, physicists have finally figured out how to tie water in knots in the laboratory. The gnarly feat, described today in Nature Physics1, paves the way for scientists to experimentally study twists and turns in a range of phenomena — ionized gases like that of the Sun’s outer atmosphere, superconductive materials, liquid crystals and quantum fields that describe elementary particles. Lord Kelvin proposed that atoms were knotted "vortex rings" — which are essentially like tornado bent into closed loops and knotted around themselves, as Daniel Lathrop and Barbara Brawn-Cinani write in an accompanying commentary. In Kelvin's vision, the fluid was the theoretical ‘aether’ then thought to pervade all of space. Each type of atom would be represented by a different knot. Kelvin's interpretation of the periodic table never went anywhere, but his ideas led to the blossoming of the mathematical theory of knots, part of the field of topology.
