Laser technology has taken a huge leap forward with the development of the world’s first digital laser system, a technology with application in multiple fields from dentistry to photo-copying. Conventional lasers are designed for specific purposes but the digital laser, developed by researchers in South Africa, promises to break new ground across a range of industries.
British scientists have created a molecule they say could greatly improve the effectiveness of sunscreens and reduce the incidence of skin cancer. Whereas most sun-screens protect against exposure to short-wave, ultraviolet B rays, the scientists are targeting long-wave UVA rays which they say cause just as much damage.

Footage of the October 7 launch illustrates a spectacular new milestone for the technology and its potential for lower cost missions into space.
SPECIAL REPORT: When it comes to hacking, the best defense is not the best offense.
Even as the U.S. government confronts rival powers over widespread Internet espionage, it has become the biggest buyer in a burgeoning gray market where hackers and security firms sell tools for breaking into computers.
The strategy is spurring concern in the technology industry and intelligence community that Washington is in effect encouraging hacking and failing to disclose to software companies and customers the vulnerabilities exploited by the purchased hacks.
That’s because U.S. intelligence and military agencies aren’t buying the tools primarily to fend off attacks. Rather, they are using the tools to infiltrate computer networks overseas, leaving behind spy programs and cyber-weapons that can disrupt data or damage systems.
The core problem: Spy tools and cyber-weapons rely on vulnerabilities in existing software programs, and these hacks would be much less useful to the government if the flaws were exposed through public warnings. So the more the government spends on offensive techniques, the greater its interest in making sure that security holes in widely used software remain unrepaired.
Moreover, the money going for offense lures some talented researchers away from work on defense, while tax dollars may end up flowing to skilled hackers simultaneously supplying criminal groups. “The only people paying are on the offensive side,” said Charlie Miller, a security researcher at Twitter who previously worked for the National Security Agency.
