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. However, constructing suitable membranes for industrial processes is a challenge. Membranes for water purification are used in many applications and different types of membranes are being developed at the moment. No membrane can filter and purify water entirely, but improvements using novel kinds of membranes are made. In the European Commission-funded project MEMBAQ (Incorporation of Aquaporins in Membranes for Industrial Applications) researchers are taking advantage of a unique structure nature has already created, when they are developing a nanotechnological invention.
The main challenge at the moment is to make membranes applicable to industrial processes. Explore further: New light on novel additive manufacturing approach.

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. In that historic encounter six years ago, the Deep Impact spacecraft released an 820-pound probe that crashed into Tempel 1 at 23,000 mph, sending a luminous plume of debris into space and allowing researchers to determine what the comet was made of.
There was so much debris, in fact, that the spacecraft could not get a clear look at the impact crater. The encounter is expected to begin about 8:30 p.m. NASA Science. European Space Agency. The European Space Agency (ESA) (French: Agence spatiale européenne - ASE) is an intergovernmental organisation dedicated to the exploration of space, 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 €4.28 billion / US$5.51 billion (2013). ESA's space flight programme includes human spaceflight, mainly through the participation in the International Space Station programme, 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. Cet avion, propulsé uniquement par ses panneaux solaires et batteries, était entré dans l’histoire en juillet 2010 : l’appareil était parvenu à effectuer un premier vol de 24 heures sans interruption.
