The decline in bees: Are pesticide surfactants to blame?
Date: Sep 2, 2013
Author: Steve Down
High levels of the trisiloxane components of pesticides have been measured in beeswax and pollen from beehives, suggesting that their effects on the health of bees should be examined in detail due to the global decline in honey bees.

Elemental discoveries: Ununpentium pr-pr-proven
Date: Sep 1, 2013
Author: David Bradley
An international team of researchers, led by physicists from Lund University, in Sweden, have verified the existence of element 115, a decade after first reports of its discovery. The team bombarded a thin film of the element americium with calcium ions and measured the pattern of X-ray photons released, to confirm predicted energies expected for the alpha decay of ununpentium.
