Superbacteria already in space, as well as a bit about the illumination of the DNA

US launches into space superbacteria to study the behaviour of antibiotic-resistant microorganisms in conditions of radiation and low gravity. On 18 February it was planned to send into orbit specially bred sample Staphylococcus aureus – he had to fly to the ISS with the Falcon rocket. The bacteria in the container with triple protection – this is done first, so as not to infect the crew of the ISS, and, secondly, to overload does not harm the microorganism. The lead researcher of the project Anita Goel (Anita Goel) suggests that under space conditions the bacteria will mutate faster, which will help to better understand the functioning of the mechanisms of drug resistance.

In Russia will create a Federal register of medical workers and health facilities. By early March electronic database should already be filled in. On filling of the base will be personnel departments – they will need to pay the full information about doctors (experience, specialization, personal data). Also the register will have complete information on each organization. It is expected that the level of access to it will be different – some information will be able to see only employees of the Ministry of health, other information – regional units of the Ministry and the health workers themselves. The question of whether to allow familiarization with part of these patients is not yet resolved.

In the United States have operated on a man whose family until recently thought he was sick with obesity. This diagnosis 57-year-old Roger Logan (Roger Logan) from Mississippi set for several years, and only recently Dr. Vipul Dev (Vipul Dev) from California gave the patient the correct diagnosis – follikulina. The tumor was attached to the stomach of the patient, her weight was about 140 lbs (over 63 kg). Roger Logan urgently needed surgery, but because of the size of folliculate his chances of survival were no more than 50%. However, all went well, and soon after the surgical intervention the patient for the first time in several years able to stand and walk a few steps.

Engineers from both biomedical doctors from northwestern University (Northwestern University) in the USA has developed a new technology powerful visualization, which allows you to see the “glow” of DNA and observe individual biomolecules, and the pattern of gene expression in General. Optical resolution of the tool is 6 nm, and this is the first time the designers managed to overcome the threshold resolution of 10 nm. It used to be that DNA, RNA and proteins do not glow themselves, but the experts at northwestern University were able to “detect” short flashes, which is then followed a long period without light. The use of new technology enables to refuse from special fluorescent dyes that are commonly used in visualization and can affect vital functions of cells.

At the University of British Columbia (University of British Columbia) microbiologists found in the intestine of newborn children of the Ecuadorian fungus Pichia associated with asthma. His presence in the community significantly increased the likelihood that the child carrier later will suffer from this disease. The researchers also suggested that the development of the disease may be due to the lack of access to clean water – but it turned out that the dependence in this case is the opposite. Children who had the opportunity to drink clean water, asthma has evolved more often.
