Great things are expected of terahertz waves, the radiation that fills the slot in the electromagnetic spectrum between microwaves and the infrared. Terahertz waves pass through non-conducting materials such as clothes , paper, wood and brick and so cameras sensitive to them can peer inside envelopes, into living rooms and "frisk" people at distance. That's not to mention the great potential they have in medical imaging. Because terahertz photons are not energetic enough to break chemical bonds or ionise electrons, it's easy to dismiss fears over their health effects. And yet the evidence is mixed: some studies have reported significant genetic damage while others, although similar, have reported none. Now a team led by Los Alamos National Labs thinks it knows why. They say that although the forces that terahertz waves exert on double-stranded DNA are tiny, in certain circumstances resonant effects can unzip the DNA strands, tearing them apart. This creates bubbles in the strands that can significantly interfere with processes such as gene expression and DNA replication. With terahertz scanners already appearing in airports and hospitals, the question that now urgently needs answering is what level of exposure is safe.

The Lunar Reconnaissance Orbiter maneuvered into its 50-km mapping orbit on September 15, which enables it to take a closer look at the Moon than any previous orbiter. This also allows for comparing previous images taken by LRO when it was at its higher orbit. These images of the Apollo 17 landing site have more than two times better resolution than the previously acquired images.

"Ask any 10 gamers what constitutes an 'indie MMO' and you'll probably get 10 different answers. But one definition that most can agree on is that an indie game lacks the financial support of a well-funded publisher. But do smaller budgets mean greater freedom? Ten Ton Hammer asked Nathan Richardsson, Executive Producer for CCP (developers of EVE Online), and Todd Harris, Executive Producer of Global Agenda, to share their thoughts on the bright future of independent MMOG development. 'By definition a niche market is a segment that is currently underserved by the mainstream providers. So, to serve that audience a developer typically needs to deliver something really different and innovative vs. just more of the same thing available elsewhere,' says Harris. 'With a big budget there could be a temptation to cover up stale gameplay by shoveling out more content or simply pumping up the marketing hype. However, for an indie developer such as Hi-Rez Studios, the game must stand on its own merits and we find that liberating.'"
