Freeze 'condemned Neanderthals'

Phylogenetic Tree Visualisation - Tree of life - Picture
This picture is a visualisation of the entire tree of life. The tree of life (cellular organisms) has three main branches:
* The bacteria (unicellular prokaryotic microorganisms) which are in focus in this picture and represented by orange nodes.
* The archaea which are probably more closely related to the eukaryotes than they are to the bacteria even though they lack a cell nucleus and represent some of the most extreme forms of life on earth. They are represented by red nodes and near the top and in the background of the picutre
* The eukarya (all cellular organisms with a cell nucleus) represented by yellow nodes and are located on the left hand side and in the background of the picture.

Crystals may have aided Viking sailors
Vikings may have used special crystals called sunstones to ensure gloomy weather did not come between them and an outing to sack British villages or discover new lands to the west, scientists have discovered. Tests aboard a research vessel in the Arctic ocean found that certain crystals can be used to reveal the position of the sun, a trick that would have allowed early explorers to ascertain their position and navigate, even if the sky was obscured by cloud or fog.

Auch die Teufel des Herrn Maxwell schaffen kein Perpetuum Mobile
Gelänge es, auf Mikroebene heiße und kalte Moleküle voneinander zu trennen, würde der zweite Hauptsatz der Thermodynamik ausgehebelt – und man könnte doch noch ein Perpetuum Mobile bauen. Den für diese Aufgabe in einem Gedankenexperiment auserkorenen Maxwellschen Dämon haben Forscher jetzt im Labor nachgebaut.

Erster privater Weltraumflughafen wird in Schweden eingerichtet
Richard Branson will ab 2012 aus Kiruna Touristen ins All schicken. Der Traum vom Weltraumflug als touristisches Erlebnis für jedermann ist alt. Abgesehen von einigen Multimillionären, die sich Plätze in bestehenden Raumfahrtprojekten erkaufen konnten, erwiesen sich jedoch bislang alle derartigen Planungen als unrealistisch. Doch der exzentrische englische Unternehmer Richard Branson, der sein Imperium mit der Plattenfirma Virgin Records begann und auch schon längere Zeit eine Fluglinie sein Eigen nennt, hat für sein nun fast ein Jahrzehnt geplantes Projekt Virgin Galactic inzwischen zumindest einen Standort festgelegt.
