Microscopic DNA walkers have been developed in the past, but they have
never managed more than three steps. These ones can manage as many as 50 steps, which means a possible walking distance of around 100 nanometres. Taking up to one hour to complete, this is more like a marathon for the nano-spider. However, researchers hope to be able to make the spiders walk faster and further in the future. Furthermore, present research is focusing on making the nano-spiders able to follow more commands and to make more decisions.

Your pronunciation is very good, excellent even. I can hear your accent but it is not pronounced (meaning strong).
It is strongest on "these", "this"
Here is a pronunciation site for you. I like to recommend it because it pronounces more variations than other sites (conjugated forms, etc)http://www.howjsay.com
