Ecological Niche Modeling is a great tool for conservation biology, phylogeography and evolutionary biology. However, as Jeff Lozier and colleagues point out in a paper in the Journal of Biogeography that the models are only as good as the data they are based on.

The basic premise of the ENM approach is to predict the occurrence of species on a landscape from georeferenced site locality data and sets of spatially explicit environmental  data layers that are assumed to correlate with the species’ range.

If you're like us, you are eagerly awaiting those July 4 fireworks displays because you get to blow stuff up using science (not just the US, Canada too, though they picked the wrong day by using July 1 for  Canada Day celebrations) - if only we could have awesome fireworks yet not ruin the planet.

Maybe we can.  A new generation of "green" fireworks is trying to take off.  Hint: that's "green" as in environmentally friendly.  And take off as in ... oh, never mind.

As a kid, there were few things more satisfying to me that being given a helium balloon... and then almost immediately letting it go for the pure enjoyment of seeing it float out of sight into the sky. For some reason, seeing a small balloon set against a vast blue background gave me a small sense of power simply from knowing that I was the one that put it up there. A silly grin would spread across my face as I stared at the small dot in the sky, knowing that only a minute earlier I held that very same balloon in my own little hand. I felt like a small part of me was launched along with it, and had just started off on a grand adventure. Since I was never able to actually go along for the ride, it was up to the limits of my imagination to envision where the balloon would land.
