MRSA use amoeba to spread, new research shows
... "Infection control policies for hospitals should recognise
the role played by amoeba in the survival of MRSA, and evaluate control procedures accordingly," said Professor Mike Brown from the Department of Pharmacy and Pharmacology at the University of Bath. "Until now this source of MRSA has been totally un...
Alternatives to the use of nitrate as a fertiliser
...hnique, two new antibodies have been produced that recognise
the enzymes of these plants and of other plant species. The results show that the contents of the GS and GDH enzymes in the root tissues of the different varieties of pea are increased when ammoniacal fertiliser is applied and, this increment is rela...

Molecular 'signature' protects cells from viruses

the alien RNA and set off the alarm: for example, they then produce what is known as the beta interferon, thereby activating specific killer cells. They also initiate the cell's suicide programme ?apoptosis. The viruses cannot then continue to breed....

the parasite's proteins. When the placenta is formed, however, a new environment is introduced with a different set of receptors. This means that a new growth niche is made available to a subpopulation of the parasites. Earlier studies have suggeste...
Baby fish 'smell their way home'

what the home reef smelt like, when they left it only a day or so after hatching." The team exposed tiny fish larvae in a tank to pure streams of water from four different reefs. To their amazement, within minutes a surprisingly high percentage o...
