California has experienced a dry 21(st) century capped by severe drought from 2012 through 2015 prompting questions about hydroclimatic sensitivity to anthropogenic climate change and implications for the future. We address these questions using a Holocene lake sediment record of hydrologic change from the Sierra Nevada Mountains coupled with marine sediment records from the Pacific. These data...
Polygenic effects have more than one cause. They testify to the fact that several causal contributors are sometimes simultaneously involved in causation. The importance of polygenic causation was noticed early on by Mill (1893). It has since been shown to be a problem for causal-law approaches to causation and accounts of causation cast in terms of capacities. However, polygenic causation needs...
Decadal and centennial mean state changes in South American summer monsoon (SASM) precipitation during the last 2,300 years are detailed using an annually resolved authigenic calcite record of precipitation δ(18)O from a varved lake in the Central Peruvian Andes. This unique sediment record shows that δ(18)O peaked during the Medieval Climate Anomaly (MCA) from A.D. 900 to 1100, providing evide...

One such critique, a paper written by Peter Saunders (PS), has been published by the think-tank Policy Exchange. It is entitled Beware False Prophets and is currently readily available on the Internet. Wilkinson and Pickett (W&P) have responded robustly to their critics and their comments are also available on the Internet [1]. In defence of their thesis that income inequality correlates (in so...
Crystal lattice parameters of a nonstoichiometric and a stoichiometric sample of the intermediatevalent compound TmSe have been measured as a function of temperature by x-ray and neutron diffraction techniques. The thermal expansion behavior of the stoichiometric sample is consistent with this material showing temporal valence Auctuations. The behavior of the nonstoichiometric sample differs fr...
I come from a family in which there have been no scientists or doctors. I was interested, however, in biology at school and started my scientific career by training in medicine at Oxford University and Guys Hospital, London. Practising as a doctor reinforced my curiosity about the biological processes underlying human disease. As a consequence, I pursued a clinical vocation in histopathology, a...
The interaction of electron-hole pairs with lattice vibrations exhibits a wealth of intriguing physical phenomena such as the renowned Kohn anomaly. Here we report the observation in bilayer graphene of an unusual phonon softening that provides the first experimental proof for another type of phonon anomaly. Similar to the Kohn anomaly, which is a logarithmic singularity in the phonon group vel...
