Hamburg  - Many USB charging devices are actually a genuine threat to the user's safety, a recent study by the Hamburg-based Computer Bild magazine found.

The magazine tested 30 charging devices, primarily for use with MP3 players with a USB port. Nine of the models had significant safety issues, the test showed. A high-voltage test even sent sparks flying in five of the devices.

Hamburg  - When Jens Kuerpick looks at photos from old, school outings, he can't help but grin. Not because he and his old buddies were just kids back then, "but because they all have red eyes in the photos," the Dusseldorf university student says.

Hamilton, 38, told the cyclingnews website that he tested positive for the steroid dehydroepiandrosterone (DHEA) at an out-of-competition test in February.

Hamilton said he was aware that an over-the-counter medication he used to treat depression contained the banned substance. He said he used the medication after his mother was diagnosed with cancer.
