The days are long gone when the noise of crickets filled the city nights. I’m sure being overtaken by the sound of traffic was depressing for many animals, but they’re not all just laying down and dying. Some city grasshoppers have started changing their tune. They’re not so depressed anymore, or so quiet.
Grasshoppers in urban areas are changing the tune of their courtship songs so as to be heard over the sound of traffic.
A research team from the University of Bielefeld Germany have discovered some grasshoppers have started to change the frequency of their song to be heard over the roar of vehicles. This evolutionary change in grasshoppers could is very exciting to see. I can only imagine what the future will bring…

Here is an awesome article on heating and insulating the self first and the house or space second. It talks about self insulation.
Modern thermal underclothing offers the possibility to turn the thermostat much lower without sacrificing comfort or sex appeal.
Of course its great to insulate your house, but should we all really be running about our houses naked in the middle of winter? I think we could all be doing the world a little favor and save some energy (not to mention moolah!) by wearing a nice sexy undershirt.
And then there’s THIS article on efficient heating of the space around one’s self. This blog post is pretty epic. She talks about different techniques to heating the person instead of the whole space. She goes through a whole trial and error process and the results of it. I’ll admit her techniques won’t work for everyone, but if that stops you, maybe you didn’t really want to do it in the first place. She managed to save buckets (I’m presuming one could fill at least one bucket with 250 crumpled ones) of money, and for people with larger houses this could save even more. She has charts and graphs and seriously covers all the questions you might have. Excellent inspiration.
So there it is. Maybe we should be turning the spyglass inward and focusing on ourselves this season. At least as far as the heating goes.
