As the survivors struggle to come to terms with their losses and begin to rebuild their lives, questions are being asked about what could have been done, and what must be done now to better protect populations. Tougher building standards for homes in fire-prone areas will be introduced, but another option under scrutiny is fire resistant shelters - are they safe, should governments play a role in their development and how should they be designed and built?

By - April 27, 2009 3 Pictures
As the name suggests, automatic or self-winding watches wind themselves using a moving weight mechanism inside the watch. All well and good if you are wearing your watch everyday, but if you happen to have a collection, you'll often find yourself faced with the fiddly task of manual winding and resetting features like perpetual calendars - a difficult job for large unwieldy fingers (men) and delicate fingernails (women) - which is where watchwinders come in. This one, the Sparta Mini from Orbita, is for the ladies. Read More
