Fotopedia Heritage, in cooperation with the UNESCO World Heritage Centre, has brought together 20,000 photos, illustrating all World Heritage Sites and 3,000 points of interests in a free application for the iPhone and iPad. 

 Fotopedia Heritage is part of Fotopedia, the first collaborative photo encyclopedia. A team led by Jean-Marie Hullot built the application while the Fotopedia community added and curated the photos thus ensuring high relevance and quality. 

Traditional mirrors work by directing the path of photons of light but atoms possessing a magnetic moment can likewise be controlled using a magnetic mirror.  A new study investigates the feasibility of using magnetic domain walls to direct and ultimately trap individual atoms in a cloud of ultracold atoms. 

A team of scientists say they have reconstructed the Earth's climate belts of the late Ordovician Period, between 460 and 445 million years ago, and their study says these ancient climate belts were surprisingly like those of the present.

The team of scientists looked at the global distribution of fossils called chitinozoans – probably the egg-cases of extinct planktonic animals – before and during this Ordovician glaciation, and found a pattern that revealed the position of ancient climate belts, including such features as the polar front, which separates cold polar waters from more temperate ones at lower latitudes.
