This article updates total factor productivity (TFP) growth in UK agriculture from 1953-2005 and shows that public and private research and returns to scale explain TFP. Cointegration and causality ...tests are used to investigate the validity of attempts to explain UK agricultural productivity with R&D and related technology variables. Then, the length and shape of the lag structures are modeled and compared with the structures that are commonly imposed on the data. The rates of return (ROR) to R&D using the data determined lags differ considerably from those obtained by imposing lag shapes. These comparisons show that the ROR to public R&D are sensitive to the lag shape as well as its length and that the omission of other technology variables, such as mechanical and chemical patents pertaining to agriculture and farm size can bias the ROR.
On December 11, 2005, Shoichiro Tsukita died at the young age of 52, after 14 months of treatment for cancer. Early in his career, Tsukita succeeded in isolating and purifying the adherens junction ...with his wife Sachiko, an accomplishment that he followed up with an impressive series of discoveries of cell adhesion and cytoskeletal molecules, including what may have been his greatest contribution to the field, the identification of occludin and the claudin family of molecules, which were watershed discoveries in the study of the molecular nature of tight junctions.

Journal Article
An obituary for Dr Marilyn Griffith is presented. Griffith gained international recognition for her research on cold hardiness in plants, particularly in winter rye and more recently in Thellungiell. ...Her discovery of plant anti-freeze proteins led to successful collaborations with scientists in many disciplines. In addition, the focus and integrity she brought to her work resulted in a collection of highly cited publications and a cadre of highly trained students and postdoctoral fellows.
