Neutrinos were first postulated in 1930 by Wolfgang Pauli, who won the 1945 Nobel Prize in Physics. “I have done something very bad today by proposing a particle that cannot be detected,” Pauli wrote…

How do new species arise? This question is still being vigorously researched in evolutionary biology. New technologies, such as genomics, provide intriguing new opportunities to investigate the…

These days I am preparing a three-hour course of statistics for particle physicists which I will give at a winter school in a couple of months. This stimulating task forces me to find nice and simple…

It is approaching fast. And it is big. The next NEO (Near-Earth Object) encounter that is. This Tuesday, a 400 m (1,300 ft) diameter rock, known as 2005 YU55, will pass by earth at a distance that is…

California is a jumble of progressive confusion.  People like to pay $15 a dozen for organic, free range chicken eggs and subsidize solar energy, for example, but a clothesline - the most…

Antibiotic resistance is a huge problem. More and more resistant strains of microbes are appearing. Needless to state that this has a huge human and economic cost. Combining this with the increasing…

My recent article  on the relationship between Einstein's Theory of Relativity and superluminal neutrinos has triggered a series of comments. Some of them were reasonable, some others not. Among…

The biodiversity of the ecological community may impact whether a species can evolve to survive climate change, according to a numerical model that simulates the effect of climate change on plants…

Insects who can scale walls are able to do so because of the thousands of tiny hairs that cover their feet and legs. The hairs have flattened tips that can splay out to maximize contact, even on…

Chess is a lifetime passion, there's no doubt about that. In twentyseven years of practice I have often found myself temporarily losing contact with my chess club, with tournaments, and online blitz…
