Megavirus chilensis is a giant virus isolated off the coast of Chile in 2010. It probably contains enough genes to encode over 1000 proteins, more than most bacteria. It seems to have originated either from a eukaryotic cell or from its … Continue reading
Archeological evidence points to the sudden appearance of strikingly modern behaviour in humans around 50,000 years ago in the form of sophisticated tools and art like painting, sculpture and engravings. A possible reason for this could be the development of … Continue reading
This on-line game lets you free a mammoth from the ice, create fire and invent the wheel, all with a time limit. Needless to say I was too slow to achieve anything! Short History of the World – Online games … Continue reading

There are increasing signs that the Higgs boson exists with a mass of between 115 and 135 GeV and that it decays into two bottom quarks. At a conference in La Thuile, in Italy, both the ATLAS and CMS experiments … Continue reading
