Dr Peter Kettlewell, a crops specialist at the university college, says grass growth in the summer varies greatly from year to year because of differences in the amount of water in the soil. The team he has headed has discovered that a cold winter produces higher levels of moisture, leading to a better crop, while warm winters reduce levels and create a less lavish lawn.
Dr Kettlewell has produced his findings in the latest edition of Proceedings of the Royal Society Biological Sciences, alongside fellow team members Jenny Easey, David Stephenson (Reading University) and Paul Poulton (Rothamsted Research).
He said: “Recently, summer weather over much of the UK has been shown to be linked to a climate pattern the previous winter, known as the North Atlantic Oscillation (NAO). After studying a long term field experiment at Rothamsted in Hertfordshire, we have discovered that this winter climate pattern is correlated with grass growth the following summer. This is because the higher the NAO index in winter (which gives a warm winter), the drier the soil in summer, leading to less grass growth.”
The findings will be of direct interest to farmers, gardeners, landscape designers and householders.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
