In a paper just published in Physical Review Letters, Guenther Walther, a mathematician at Stanford University in California, shows that the observation that the number of neutrinos detected decreases when sunspots are plentiful is no more than an error in counting.

As the researchers report in a forthcoming issue of Physical Review Letters, they managed to hold significant numbers of isolated rubidium atoms in place by shining a laser beam on to an array of microscopic lenses.
