Research teams are trying different approaches within the nanotechnological field to improve water membrane technologies. One of these is to improve water purification by using nature’s own water-transporting channels, aquaporins.

This true-color image shows North and South America as they would appear from space 35,000 km (22,000 miles) above the Earth. The image is a combination of data from two satellites. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA’s Terra satellite collected the land surface data over 16 days, while NOAA’s Geostationary Operational Environmental Satellite (GOES) produced a snapshot of the Earth’s clouds.

It's not exactly young love, but some might find it romantic. On Valentine's Day, an aging Lothario that has been flitting from beauty to beauty through the solar system will make his final stop, taking pictures of a battered dowager to send to the folks back home before disappearing forever. The Stardust spacecraft, which has already taken images of asteroid Annefrank and captured interstellar dust from comet Wild 2, on Monday night will swing by comet Tempel 1. There, it will take new pictures of the devastation wrought on the comet by NASA's 2005 Deep Impact mission.
The European Space Agency ( ESA ) ( French : l' Agence spatiale européenne - ASE ; German : Europäische Weltraumorganisation ) is an intergovernmental organisation dedicated to the exploration of space , currently with 20 member states. Established in 1975 and headquartered in Paris, France , ESA has a staff of more than 2,000 with an annual budget of about €4.02 billion / US$5.38 billion (2012). [ 1 ] ESA's space flight program includes human spaceflight, mainly through the participation in the International Space Station program , the launch and operations of unmanned exploration missions to other planets and the Moon, Earth observation, science, telecommunication as well as maintaining a major spaceport , the Guiana Space Centre at Kourou , French Guiana , and designing launch vehicles. The main European launch vehicle Ariane 5 is operated through Arianespace with ESA sharing in the costs of launching and further developing this launch vehicle.

Encore expérimental, l’avion Solar Impulse du Suisse Bertrand Piccard a décollé ce matin de l’aéroport militaire suisse de Payerne pour effectuer son premier vol international. Il devrait atterrir dans la soirée à Bruxelles. C’est sous un grand ciel bleu vers 6h40 GMT que le Solar Impulse a décollé de Suisse ce vendredi, a constaté l’ AFP .
