An ambitious project is underway to build the world’s smallest electronic nose.
If the project succeeds, it is expected that the technology would have many potential applications in areas such as environmental monitoring, healthcare and food safety.
The aim is to combine the odour sensors together with the signal processing components on to a single silicon chip, around a square centimetre in size. The instrument would require very little power and could be held comfortably
Food quality will fall, food costs will rise and stored food will be damaged. Historical relics may be lost to insect attack, rodent and insect infestations on public transport will swell, and fungal contamination of stored food will increase. According to a recent meeting of the Society of Chemical Industry (SCI) Pest Management Group, these may be the consequences of a worldwide phasing out of the crop protectant methyl bromide (MB).

New technique could help rapid detection of infecting organisms in hospitals and prove authenticity of foods such
Researchers at the University of Wales, Aberystwyth (UWA) are about to put ultra-violet Raman spectroscopy through its paces as a new technique for studying biological materials.
Dr Roy Goodacre and colleagues in the Institute of Biological Sciences have been awarded a grant worth £306,291 by the Engineering and Physical Sciences Research Council (EPSRC) to develop an
A Commission survey on the patenting and publication by EU scientists and organisations from industry and academia involved in biotechnology and genetic engineering research, that highlights the need for support to and training of academics in the proper use of the patent system. Public research organisations can handle patent applications almost as professionally as industrial organisations and without significantly delaying the publication of results that are subject to patent applications. In cont
Homoeopathic remedies are no better than placebo for the treatment of asthmatic patients who are allergic to house dust mite, but there is a difference in response between homoeopathy and placebo, concludes a study in this week’s BMJ.
The research team identified 242 asthmatic people allergic to house dust mite. Participants received either homoeopathic therapy or placebo and were assessed over 16 weeks.
They found no improvement in lung function or quality of life between those tre
HIV patients at risk of a potentially fatal hypersensitive reaction to the antiretroviral drug abacavir could be identified by genetic testing before drug therapy has started, suggest authors of a fast-track study in this week’s issue of THE LANCET.
The use of the HIV antiretroviral drug abacavir, a potent HIV-1 nucleoside-analogue reverse-transcriptase inhibitor, is complicated by a potentially life-threatening hypersensitivity syndrome in about 5% of cases. Genetic factors influencing the
