The Atlantic Ocean plays a much larger role in controlling summer climate in Europe and North America than previously thought, say scientists in a paper published in the journal Science on 1 July 2005.
The scientists, from the NCAS Centre for Global Atmospheric Modelling in Reading, have shown that over the last 100 years several swings in the temperature of the North Atlantic Ocean, each lasting decades at a time, have affected summer climate on both sides of the Atlantic.
Lead author Rowan Sutton said: ‘For the first time we have shown that changes in the Atlantic Ocean can actually drive the climate we experience either side of the Pond. By comparing observations with our results from state-of the-art climate models, we have shown that when the North Atlantic Ocean is warm, summers in the United States are warm and dry, and droughts more frequent. Conversely, when the ocean is cool, U.S. summers are cool and wet. The effects on European summers are more subtle but still important.’

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
