it is required by law to keep an eye on any human embryo created in any other way than by the natural proceedings. In December 2002, the High Court seriously undermined the HFEA's position when it decided that its ruling that allowed the Hashmi family to use embryo selection had exceeded its legal powers. In May, however, the appeal court overturned that judgment and cleared the last legal hurd...

Neuropeptides are emerging as key components in the hippocampal neurogenic niche in health and disease, regulating many aspects of neurogenesis and the synaptic integration of newly generated neurons. This review focuses on the role of neuropeptide Y in the control of stem/precursor cells in the postnatal and adult hippocampus. It is likely that neuropeptide Y releasing interneurons are key sen...

Development of yeast artificial chromosome (Y AC) vectors, molecular cloning of large segments of chromosomal DNA, and their propagation in yeast cells has become feasible. Overlapping Y AC provides a route to the development of physical maps of entire mammalian chromosomes. A rapid method was developed to isolate and sequence termini of Y AC inserts quickly. The Y AC clone is digested wit...

in this paper, we prove the generalized hyers-ulam(or hyers-ulam-rassias ) stability of the following composite functional equation f(f(x)-f(y))=f(x+y)+f(x-y)-f(x)-f(y) in various normed spaces.

There are two ways to write about a branch of science for an audience of non-scientists; one is to try and make the audience understand the basic principles of the subject, the other is to entertain them by a rapid succession of pieces of information. Steve Jones's latest book falls firmly into the second category. Given that the subject is the biology of the human male, there is of course no s...

Multiple kernel learning aims at simultaneously learning a kernel and the associated predictor in supervised learning settings. For the support vector machine, an efficient and general multiple kernel learning (MKL) algorithm, based on semi-infinite linear progamming, has been recently proposed. This approach has opened new perspectives since it makes the MKL approach tractable for large-scale ...
