Study Finds Cellphone Use Tied to Changes in Brain Activity

cell phone and the brain

Researchers from the National Institutes of Health have found that less than an hour of cellphone use can speed up brain activity in the area closest to the phone antenna, raising new questions about the health effects of low levels of radiation emitted from cellphones.

Earth is overdue a solar storm as the sun enters its most active period

 The world is overdue a ferocious ‘space storm’ that could knock out communications satellites, ground aircraft and trigger blackouts – causing hundreds of billions of pounds of damage, scientists say.

Sexual Reproduction in Space Will Likely be Impossible Says Nasa

reproduction in space

Sexual reproduction is likely to be impossible in space due to cosmic radiation bombarding the human body.

Researchers at the agency’s Ames Research Centre in California found that without effective shielding on spacecraft, powerful proton particles would probably sterilize any female embryo conceived in deep space.

32 Percent of Russians Think the Sun Revolves Around Earth

Many Russians are a little off on their science.

Does the sun revolve around Earth? Is radioactivity a human invention? Did humans ever live side by side with dinosaurs? A surprising number of people in Russia answered those and other questions with a resounding “yes.”

Astronauts Could One Day Reach Mars by Riding Asteroids

asteroids-space-taxi-mars-travel

In 2005, Japan’s unmanned Hayabusa spacecraft (illustration) successfully landed on an asteroid.

Getting to Mars is going to involve building a huge spacecraft and loading it up with tons of fuel and radiation shielding. Unless, that is, we could just tag along with a spacecraft that’s already headed in that direction, like an asteroid.

Using a custom-built camera the size of a refrigerator, Florida researchers have made the world s first crude pictures of X-rays streaming from a stroke of lightning

It might look like an homage to the iconic 80s gameshow Blockbusters hosted by Bob Holness.  But this crude image is actually the world’s first picture of X-rays streaming from a bolt of lightning.

Worries About Radiation Exposure to Children in the Dentist’s Chair

An image from a cone-beam CT scanner used by dentists.

Because children and adolescents are particularly vulnerable to radiation, doctors three years ago mounted a national campaign to protect them by reducing diagnostic radiation to only those levels seen as absolutely necessary.

Study: WiFi Makes Trees Sick

City trees are becoming sick from wireless radiation from local area networks and mobile phones.

Radiation from Wi-Fi networks is harmful to trees, causing significant variations in growth, as well as bleeding and fissures in the bark, according to a recent study in the Netherlands.

Physicist Finds Universe Existed Before the Big Bang

universe

Sir Roger Penrose, renowned physicist, found evidence the universe existed before the Big Bang.

The current cosmological consensus is that the universe began 13.7 billion years ago with the Big Bang. But a legendary physicist says he’s found the first evidence of an eternal, cyclic cosmos.

Random Radiation Is Not Cool
Are scanners being employed at roadway checkpoints to “radiate Americans” with dangerous X-rays designed to peer inside their vehicles? Yes, according to Alex Jones conspiratorial website Prison Planet, and this time, the mainstream media agrees, at least in part…

New Solar Cells Can Produce Electricity From Light and Heat Simultaneously

light and heat

A small PETE device made with cesium-coated gallium nitride glows while being tested inside an ultra-high vacuum chamber.

Though the sun offers us a couple options for exploiting its energy — light and heat — we’ve always had to choose to use one at a time, because solar-energy technology hasn’t been able to capture both typs of radiation simultaneously. Stanford researchers say that’s about to change, however. Their new breakthrough could put solar power on par with oil, price-wise. (Video)
