To create ideal conditions that ensure almost the same size of microbial colonies (the relative standard error is about 1%) or Poisson distribution for their number, a special "ordered seeding" technique and a "poissoner" device were invented. They are most popular with molecular geneticists who need accurate estimates of mutation rates, recombination, transformation, survival, etc.
06.04.2009In the film "Size Matters", famous Russian scientists fascinatingly tell what nanotechnology is and what nanotechnologists do.
06.04.2009The CATSPER1 protein is part of the ion channel that launches calcium ions into the cell. As a result, the tail of the sperm begins to beat with increased energy. In the absence of this protein, the sperm simply does not have the strength, speed and mobility to fertilize an egg. Smith and his colleagues propose to cause the same condition artificially by blocking calcium channels with the help of medications.
06.04.2009The database is designed to provide material for scientific research in the field of inheritance of various human qualities. Most of these studies are conducted using information about twins.
06.04.2009Time will tell what these two works will mean for humanity. Enthusiasts of artificial intelligence can say that scientists have shown its ability to compare with the intelligence of humans. Anthropocentrists will object that we are talking only about special cases and it is premature to put an equal sign.
06.04.2009The message published on April 1 in a variety of online publications about the "Grubber-2", of course, is a joke. Unfortunately, part of this joke is the bitter truth: the text, although composed by a living person, is so delusional that many readers believed that it was written by a computer, was published in a journal claiming to be scientific.
06.04.2009The corporate norms existing among doctors, as before, support the practice of informal payment. Payment in the form of gratitude, made on the initiative of the patients themselves, is recognized by the overwhelming majority of doctors as a fully justified material compensation for the labor they spend. Extortion of money from patients, that is, receiving payment at the insistence of a doctor, is almost universally condemned.
03.04.2009In order for Russians to be able to buy domestic generic drugs in pharmacies that are not inferior to imported analogues, the Russian pharmaceutical industry needs modern equipment and qualified personnel. If you translate this phrase into the language of economics, then by and large, nothing but huge investments are needed for domestic pharma. Moreover, money will have to be invested not only directly in the pharmaceutical industry, but also in science and education.
02.04.2009The list of senile eye diseases includes glaucoma, macular degeneration, various forms of retinopathy, cataracts, age–related hyperopia. Science knows that one of the reasons for such disorders is the accumulation of oxygen free radicals in the body. By neutralizing reactive oxygen species in the mitochondria of eye tissues, "Skulachev ions" restore vision.
02.04.2009The composition of the miracle pill includes aspirin, three drugs to reduce blood pressure and a statin that reduces cholesterol levels in the blood. According to researchers, the use of a new pill that reduces blood pressure and cholesterol can potentially reduce the number of cardiovascular diseases by 62%, and the number of heart attacks by 48%.
02.04.2009For a long time, newspapers and magazines of the world, serious and not so serious, have been delighting readers with practical jokes on the first of April. Let's remember the most talented!
01.04.2009After analyzing the DNA of more than 1,000 inhabitants of Iceland, experts from the biotech company deCODER claim that they were the first to isolate a single gene responsible for male potency and penis size in the inhabitants of the country.
01.04.2009Review of recent developments in nanomedicine and nanobiotechnology in the latest issue of the digest "Nanotechnology in the world" (February 2009).
01.04.2009The state corporation announced the cooperation between Rusnano and the government of St. Petersburg in December 2008. The corresponding agreement was signed by the General Director of Rusnano Anatoly Chubais and the Governor of St. Petersburg Valentina Matvienko. The cooperation provides for joint work on the implementation of state policy in the field of nanotechnology, the creation of conditions for the commercial use of the results of developments, as well as the implementation of investment and infrastructure projects and educational programs in the field of nanoindustry
01.04.2009Checking (by sending out computer-generated quasi-scientific texts for publication) of all scientific journals on the list of the Higher Attestation Commission, gave a good result: out of the first fifty verified journals, only one succumbed to this insidious trick.
01.04.2009For a long time, when I was young, I wanted to write an article, or even a whole book of criticism of Darwinism. I also came up with the name for such an article or book, "The Bible from the Devil." In such a title, these two themes are intertwined: Satan and Darwinism.
01.04.2009The city will not support programs to reduce harm from drug use and spread knowledge about condoms. Instead, at HIV prevention classes in schools, children will be introduced to Russian culture, religion and family values and will be told about the usefulness of sports and the harm of casual sexual relations.
01.04.2009A lot has been written about the properties of water, misconceptions (and conscious deceptions) and it is not worth repeating. The main difference between "macro" water from "micro" and "nano" is that the authors of mystical hypotheses operate with familiar (trivial) concepts: memory, emotional impact, magnet, music, snowflake shape, etc. Any Chumak can "create" such water – without special knowledge and equipment.
31.03.2009Good earnings of parents are reliably associated with health, education and, in turn, the situation of their children. Poverty, on the contrary, leads to constant physiological stress, a decrease in working memory and poor academic performance in kindergarten and school.
31.03.2009Chubais' goal is to create a nanomarket, to make the process of industry development "irreversible", when, without the participation of the state corporation, Russian business will generate demand and supply for nanotechnology and related products. Another benchmark is the volume of nanotechnology exports, which should grow to 180 billion rubles in 2015. In order to achieve these goals, the work of Rusnano will undergo significant changes starting in the fall of 2009.
