Broccoli is one of western Europe`s most popular and widely consumed vegetables. However, its shelf life is restricted to about 5 days at room temperature, making distribution and storage of the product difficult. Recent research presented today at the Society for Experimental Biology conference in Swansea could help us understand the genetics of this situation and may even lead to `supervarieties` of broccoli.
The popularity of broccoli is on the increase and it is used increasingly in value added products such as frozen foods and ready meals. In the UK, broccoli available in the summer is produced domestically. However, during the winter months the majority of the broccoli available in supermarkets has made the long journey from Spain - not an easy thing when the product itself has a shelf life of only 5 days.
Evy Mathas, a PhD student at Horticultural Research International, Wellesbourne, is attempting to understand this relatively rapid deterioration - research which may lead to improved commercial varieties. Senescence - the deterioration of the product - is characterised by a yellowing of the broccoli floret and a loss of water. In order to study this process, Ms Mathas carried out an extensive field trial in 2001, growing different varieties of broccoli and carrying out a detailed analysis on each post-harvest day. She has found a dramatic difference between these varieties. Some senesce in as little as 2 days, whilst others remain edible for 4 at room temperature. Her biochemical and molecular analysis has shown that this senescence is a result of a rather rapid loss of chlorophyll and a slight loss of protein from the floret.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
