Too much red meat is a risk for the life
April 16th, 2009
The news is the result of a study, published on “Archives of Internal Medicines”, lead from the investigators of the National Cancer Institute who have monitorato 500,000 subjects.
From the result it is emerged that for those who has in the diet a high concentration of red or worked meat is more high risk than dead women, and in particular risk the cancer and cardiac diseases. From the study evince moreover that, to facilitate the risk to develop the cancer it would be the high temperature demanded from the baking of the meat.
High who runs a risk eats 160 grams of red meat or worked every day, to the opposite one instead, who she consumes 25 grams, cioé a fettina of bacon. According to the investigators, 11% of deaths in less would be had between men and 16 between the women if the doses and the consumption of this food were only reduced.
Diagnosis of the taken care of melanoma more with the putting to point of a new test
April 16th, 2009
A new and sure test will be able to establish with benign certainty if draft of in or the malignant ones: put to point from the investigators of the University of Saint Francisco (USA) and it is based on the measurement of some marking determined present differences in genetic.
Until today the diagnosis of of the malignant tumor of the skin it comes made through the direct observation (to microscope) of the biopsies of woven. But since in some cases the outcomes can be ambiguous proceed with the surgical removal and the appraisal of linfonodo the lookout, an minium-invasive participation for the patient who resolves the problem definitively.
The search, published on Proceedings of the National Academy of Sciences, illustrates a test that has been demonstrated valid also making the test with the traditional methods.
The future clean technology will be fed from virus
April 16th, 2009
Soon a microorganism for feeding cellular batteries of and readers MP3 will be had.
The last one found of the investigators of the Mit is, the Institute Massachusetts of directed Technologies of Boston from Angela Belcher, that they are resolutions to plan genetically of the viruses in order to obtain the pole negative and that positive one of an A battery the Ionian ones of lithium.
According to how much law gannet Science review the battery will produce clean energy taking advantage of the virus “M13 ″, that it kills bacteria, which cloned and genetically modified.
A traditional battery is made of four fundamental members: the two poles, anode and cathode, electrolytes (substances that, in water or other dissolvent, form atoms electrically cargos, Ionian) for the passage of current from a pole to the other, the separator of the two poles.
Al place of traditional oxide of cobalt or lithium for the positive pole and grafite for that negative, the scientists are resolutions to construct the poles of the battery, with particles turn them of the virus M13, a virus killer of the bacteria or bacteriophage, innocuous for the man. The poles turn them have been inserted in a dwarf substrate tubes.
