Astronomers are baffled by the discovery of a pulsar - a tiny spinning stars, heavier than the sun and smaller than a city - that emits different types of radiation at different times.
Radiation causes ten times as much structural damage to electronic materials at the atomic level as previously believed, say scientists using a new investigation technique.
With a solar storm washing over the Earth this weekend, it's welcome timing for a new solar radiation warning system that gives more warning than ever before.
If there's any evidence of ancient life on Mars, it's likely to be found near the surface, new research suggests - dramatically upping the chances that it'll be discovered by the Curiosity rover, set to land next month.
Researchers at the Georgia Tech Research Institute (GTRI) have created a new prototype radiation detection device for use at ports, border crossings, airports and elsewhere.
Factory Fifteen has released a short, yet haunting sci-fi film dubbed GAMMA. The surreal movie depicts a post-nuclear future, in which the earth is riddled with dangerous radiation.
A federal judge has thrown out most provisions of a San Francisco law requiring phone retailers to display the amount of radiation emitted by each device.
Russian city Chelyabinsk - widely known as the most polluted in the country - is using taxpayers' money for a search engine optimisation project aimed at cleaning up its image (though not the city itself).
Tawkon has been making quiet ripples in the smartphone market. But most people only heard of the Israeli firm after the dramatic rejection of its app by the chief Apple guru himself - Steve Jobs.
While US personnel in Japan have been issued with supplies of potassium iodide in the event that they need treatment for radiation sickness, it's very much a last-ditch solution.
Radiation from Japan’s damaged Fukushima nuclear power plant is already reaching the US, and is more difficult to predict than the weather, say University of Maryland atmospheric scientists.
The debate over whether cellphones affect the brain rumbles on. The latest study shows a measurable effect on brain activity - but one which may or may not be harmful, say the team.
