Student science experiment finds plants won't grow near Wi-Fi router

Student science experiment finds plants won't grow near Wi-Fi router
Five ninth-grade young women from Denmark recently created a science experiment that is causing a stir in the scientific community. It started with an observation and a question. The girls noticed that if they slept with their mobile phones near their heads at night, they often had difficulty concentrating at school the next day. They wanted to test the effect of a cellphone's radiation on humans, but their school, Hjallerup School in Denmark, did not have the equipment to handle such an experiment. So the girls designed an experiment that would test the effect of cellphone radiation on a plant instead. The students placed six trays filled with Lepidium sativum, a type of garden cress, into a room without radiation, and six trays of the seeds into another room next to two routers that according to the girls' calculations, emitted about the same type of radiation as an ordinary cellphone. Over the next 12 days, the girls observed, measured, weighed and photographed their results.

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: [2] Brooks, C.E.P. (1951).

There is No Mistaking The Evidence, Cannabis Cures Cancer Cannabis is one of the most powerful healing plants in the world and it makes cancer essentially disappear. Cannabis compounds are responsible for halting the growth factors that are responsible for metastatic growth. Although there has been scientific evidence that marijuana can shrink and even kill tumors since the 1970s, much of the recent public interest in this research has been inspired by Run From The Cure, a documentary about a Canadian man who claims that the concentrated oil from the cannabis plant has cured his skin cancer. He then tries the cure on a number of other cancer victims in his community with similar results. Researchers have now found that the compound, called cannabidiol, has the ability to ‘switch off’ the gene responsible for metastasis in an aggressive form of breast cancer. A team from the California Pacific Medical Center, in San Francisco, first spotted its potential five years ago, after it stopped the proliferation of human breast cancer cells in the lab.

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.

The many uses for Apple Cider Vinegar There are approximately 8 bajillion uses for apple cider vinegar. Although, to be perfectly honest I really hated the stuff for a long time. My first experience with apple cider vinegar (or ACV as the cool kids call it) was during my college days when I was attempting to get rid of a little wart on my toe. I kept gagging at the smell. My how things change. Now I gag on the smell of fake perfumes, toxic cleaners, and baby diapers. What is Apple Cider Vinegar Apple cider vinegar is a type of vinegar made from cider or apple must and has a pale to medium amber color. Most people are familiar with ACV as an ingredient to be used in salad dressings, marinades, vinaigrettes, food preservatives, chutneys, etc. Uses for Apple Cider Vinegar Internal Health Let’s talk internal health, first. To take orally, simply mix 1 – 2 tablespoons of apple cider vinegar into a cup of filtered water (or you could mix it with herbal tea). Of course, you can add ACV into salad dressings. Beauty Home

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.

The Rising Spoon: Monthly Veg-ucation: Baked Organic Zucchini Boats Two Ways Ready for your first summertime veggie post? Last month I discussed cauliflower and the month before was asparagus. This month the ladies in our real food vegetable circle are focusing on summer squash. I could have chosen several different summer squashes, but opted to try a new zucchini recipe after picking up a few pounds of the organic produce at my local farmer's market a few weeks back. After secretly grating it into my boyfriend's scrambled eggs for a few weeks (shhh...he doesn't like squash and still has no idea) and sauteing it in pasta dishes, I couldn't wait to try this cheesy baked and stuffed dish. Over the past year or so, zucchini boats with pepperoni pizza toppings have been super popular all over Pinterest; however, I wanted a filling with a bit more substance. I even went so far as to plan a taco flavored zucchini boat with ground beef seasoned with my homemade spicy taco seasoning, but I ended up not having enough zucchini to try it out. Another bonus?

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.

Giant weed that burns and blinds spreads across Canada A huge, toxic plant that can burn skin and cause permanent blindness has been found for the first time in eastern Ontario, prompting calls for a federal response to contain the spread of the poisonous plant as fear grows no province is immune. A forestry official confirmed two new findings of giant hogweed last week in Renfrew County, west of Ottawa. It has previously been spotted in Newfoundland, New Brunswick, Quebec, southwestern Ontario, Alberta and British Columbia. About 50 plants were spotted in Toronto’s Don Valley two weeks ago. Contact with the weed’s clear, watery sap can be very dangerous, Jeff Muzzi, Renfrew County’s forestry manager and weed inspector. “What it does to you is pretty ugly,” said Mr. Even a tiny trace of sap applied to the eye can singe the cornea, causing temporary or permanent blindness, he added. Most provinces have not authorized official weed inspectors to destroy the poisonous plant because it does not impinge on agriculture. Mr. Mr. National Post

Surface structure controls liquid spreading Researchers at Aalto University have developed a purely geometric surface structure that is able to stop and control the spreading of liquids on different types of surfaces. The structure has an undercut edge that works for all types of liquids, irrespective of their surface tension. By using the edges, liquid droplets can be confined and patterned on the surface in defined forms, such as circles. 'Patterning liquids into well-controlled circles is essential in applications such as the production of lenses that begin in liquid form and are then cured. According to the method developed by researchers, the effect of the edge structure on controlling liquids is based purely on geometry. Like an aqueduct without walls With the help of the structure, liquid can also be guided by the edges in a desired direction on the surface. 'These kinds of measurements often involve the guidance of very small fluid flows in microchannels.

(75) Timeline Photos A new probe for spintronics The spin Hall effect (SHE) enables us to create spin current in non-magnetic materials without using ferromagnetic materials. It is a crucial element in the central idea behind spintronics, that of manipulating currents of spin instead of currents of charge. Since the first experimental report on the SHE in semiconductors in 2004, the phenomenon and its mechanism have been intensively studied to find out more efficient and economical methods of generation of the spin current, both in semiconductors and metals. The inverse process of SHE (ISHE) is similarly recognized as a key step to be mastered in order to convert the spin current back into a charge current. So while both the SHE and its inverse are important for the potential applications, there are few examples of their use as an electrical detector of more fundamental properties of condensed matter.
