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.

What is A Planet? What is A Planet? Description What is a planet? Pornography, kids and sex education: what to do? - Health More kids at ever younger ages are accessing pornography online, according to a range of studies, but there's not much consensus about what, if anything, should be done by parents or teachers to address the issue. Today in Winnipeg, a children's advocacy group called Beyond Borders will host a symposium entitled "Generation XXX, the pornification of our children." "The porn industry is the country's main sex educator of our boys and girls," says Cordelia Anderson, one of the experts scheduled to speak at the symposium, referring to the U.S.

Bees May Use Electricity to Communicate The electric fields that build up on honey bees as they fly, flutter their wings, or rub body parts together may allow the insects to talk to each other, a new study suggests. Tests show that the electric fields, which can be quite strong, deflect the bees’ antennae, which, in turn, provide signals to the brain through specialized organs at their bases. Scientists have long known that flying insects gain an electrical charge when they buzz around. That charge, typically positive, accumulates as the wings zip through the air—much as electrical charge accumulates on a person shuffling across a carpet. And because an insect’s exoskeleton has a waxy surface that acts as an electrical insulator, that charge isn’t easily dissipated, even when the insect lands on objects, says Randolf Menzel, a neurobiologist at the Free University of Berlin in Germany.

Infinite-capacity wireless vortex beams carry 2.5 terabits per second American and Israeli researchers have used twisted vortex beams to transmit data at 2.5 terabits per second. As far as we can discern, this is the fastest wireless network ever created — by some margin. This technique is likely to be used in the next few years to vastly increase the throughput of both wireless and fiber-optic networks. These twisted signals use orbital angular momentum (OAM) to cram much more data into a single stream. In current state-of-the-art transmission protocols (WiFi, LTE, COFDM), we only modulate the spin angular momentum (SAM) of radio waves, not the OAM. science/Pages/Elementary-Resources.aspx Sign In Science Elementary Resources The problem with #slacktivism AFP Photo They did not bring back our girls.

First-ever high-resolution images of a molecule as it breaks and reforms chemical bonds When Felix Fischer of the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) set out to develop nanostructures made of graphene using a new, controlled approach to chemical reactions, the first result was a surprise: spectacular images of individual carbon atoms and the bonds between them. "We weren't thinking about making beautiful images; the reactions themselves were the goal," says Fischer, a staff scientist in Berkeley Lab's Materials Sciences Division (MSD) and a professor of chemistry at the University of California, Berkeley.

The University of Alberta law student forgot to turn off his headlights on Wednesday after parking in a residential neighbourhood around 109 Street and 74 Avenue. When he returned from the university hours later, his battery was dead. And there was a note on his windshield.

National Grid EMF - Sources of EMFs The diagram shows how the magnetic field varies over a typical house. The peaks come from the various appliances, and they are superimposed on a low background field, which varies only slightly across the house. Appliances are present in every home and fields come from everything from your kettle to your TV - even a mobile phone. A minority of homes in the UK are close enough to an overhead power line, an underground cable or a substation for that to be the main source of the background field. But in most homes, the background field comes from low-voltage distribution wiring.
