Gingerbread houses are a much-admired and tasty holiday tradition in many parts of the world. Yet until now, no one we know of has tried to improve their design and construction by using lasers. That’s precisely what one engineer with a second-hand laser cutter and some architectural curiosity did. The result is high precision … but you don’t want to eat it.

Johon von Konow, an engineer in Sweden, spends his days developing mobile phone concepts for Sony Ericsson and Huawei. At night, he and his wife, Maria, are always on the lookout for new things to try.

Laser detects roadside bombs

Lab scientists are pitching a new high-tech laser that is able to detect roadside bombs before they explode, potentially thwarting the deadliest weapon in Iraq and Afghanistan.

Roadside bombs, known as improvised explosive devices or IEDs, account for 60 percent of coalition soldiers’ deaths, according to NATO figures. Finding a way to improve on — or at least replace — bomb sniffing dogs is therefore a priority abroad and at home.

Laser eyed to remove space junk

Publication: msnbc.com   Date: March 15, 2011   View Article

NASA-affiliated scientists have proposed using a low-powered, ground-based laser to nudge pieces of space debris off of collision courses with each other.

The proposal, presented in a paper submitted to Advances in Space Research and posted to arXiv.org, is a low-cost solution to the growing problem of space junk.
