We are living in exceptional times. Scientists tell us that we have 10 years to change the way we live, avert the depletion of natural resources and the catastrophic evolution of the Earth’s climate.
The stakes are high for us and our children. Everyone should take part in the effort, and HOME has been conceived to take a message of mobilization out to every human being.
Incredible footage of hermit crab changing shells with anemones!
In this exciting excerpt from the third season of Jonathan Bird’s Blue World, Jonathan films a hermit crab changing shells and then also transferring its anemones from one shell to the other. This is extremely rare footage of a seldom-seen behavior!

A profile of Walter Lewin, a physicist at the Massachusetts Institute of Technology (MIT), who is considered to be an exception even among exceptional teachers. Visit physicsworld.com for more videos, webinars and podcasts.

Size of the nanoscale
The scale of the universe
Just how small is “nano?” In the International System of Units, the prefix “nano” means one-billionth, or 10-9; therefore one nanometer is one-billionth of a meter.
