International award for peace among hijab and mini-skirt

International Centre for Journalists (ICFJ) and United Nation Alliance of Civilizations (UNAOC) awarded two Egyptian and one Serbian journalists, Tarek Mounir, Asma Fathy and Sasa Milosevic for joint project �Hijabskirt Info� as an unique multimedia Web site analysing the difference in cultural perceptions, starting with the Muslim hijab and the Western miniskirt. The X-Cultural Reporting Awards will be presented at a ceremony in Rio de Janeiro, Brazil, on May 29, 2010 at Third Forum of the Alliance of Civilisations.

Young Sun and Venus.

So far, relative to the Earth and Venus means the following. Around the period Archean (3.8 billion years ago - 2.5 billion years ago), these planets have the same dense atmosphere of carbon dioxide (97%) and other gases. Since the Earth at a distance of 150 million km., and Venus 108 mln.km., it was clear that today's temperature readings of the planets were to be in the past; on Venus, +460[sup]o[/sup]C, on the Earth within the current standards. Accordingly, it rained on the Earth, which washed the carbon dioxide from the atmosphere (CO[sub]2[/sub] has the ability to dissolve in water), and on Venus oceans turned into steam, which, given the weakness of the planet's magnetic field rose so high above the surface, which was carried by the solar wind in interplanetary space.

Once more fact for thought about advent of life on Earth.

Like many discoveries, this was not the result of purposeful research, but rather a sudden and very interesting branch in another, equally important, pilot experiment - a study of anaerobic methane oxidation associated with nitrites and nitrates.

Mars - who's first?

In recent years, the habitual periodic table of elements has grown not only in the 3-d direction (axis Z), due to isotopes, but also in the 2-dimensional field on account of theoretically found dozens of new chemical elements. Some of them have already been received, some yet to be synthesized in the laboratory. Obvious need for new chemical elements for the various innovations in science and technology is already so relevance, that the first-ever who gets access to new opportunities, through these, you can redistribute political forces in today's arena of the world. It is understood by most. Also expected is that the possible source of new chemical elements is Mars. If you look at pictures of Mars we can clearly see the characteristic metallic gleam of certain entities, which may well represent the deposits of various chemical elements. Most of the theoretically derived elements fall within the following external description: "color is unknown, but probably metallic and silvery white or gray." The same chemical elements, which were obtained directly from the laboratories, had the following external features: "color unknown, but probably metallic"- or: "probably silvery liquid�. It is worth noting that the mass obtained new chemical elements is negligible, and represents a numerical value from 1 to multiple cores, so the value of the color characteristics assigned to tentatively.

Blood pressure is a mechanical process!

Since the opening of the first gene STK39 [fig 1, fig. 2](function: may act as a mediator of stress-activated signals. This gene encodes a serine/threonine kinase that is thought to function in the cellular stress response pathway. The kinase is activated in response to hypotonic stress, leading to phosphorylation of several cation-chloride-coupled cotransporters. The catalytically active kinase specifically activates the p38 MAP kinase pathway, and its interaction with p38 decreases upon cellular stress, suggesting that this kinase may serve as an intermediate in the response to cellular stress) in the field of genetics, which is responsible for activating the pressure rise was not much time, and the scientific community had almost come to an understanding of the essence of this complex process. From the very beginning of genetic research in this direction was assumed that the STK39 gene is just the tip of the iceberg and that there are still many studies before we can draw at least some concept of genetic regulation of blood pressure. One of the last three modern research in this field, shed light on this perspective was provided by article �Genome-wide association study identifies eight loci associated with blood pressure� Nature Genetics (June 2009, Volume 41) which contains the test results for 2,5 million genotyped for the relationship of systolic and diastolic blood pressure by genotype (European, Asian, Indian). This analysis revealed 8 new loci:

Polyoxometallate - crystals future optical, magnetic, medical and other applications.

In chemistry, a [bold]polyoxometalate[/bold] (abbreviated [bold]POM[/bold]) is a polyatomic ion, usually an anion, that consists of three or more transition metal oxyanions linked together by shared oxygen atoms to form a large, closed 3-dimensional framework. Examples include vanadium(V), niobium(V), tantalum (V), molybdenum(VI), and tungsten(VI).

Identified new genes responsible for obesity

For some time it was believed that the responsibility for body mass index (BMI) in humans take on only two loci (is the specific location of a gene or DNA sequence on a chromosome), a FTO (fat mass and obesity associated (protein coding) fig. 1, fig. 2) and MC4R (function: receptor specific to the heptapeptide core common to adrenocorticotropic hormone and alpha-, beta-, and gamma-MSH; this receptor is mediated by G proteins that stimulate adenylate, cyclase). This fact has been generally accepted, till in the journal Nature Genetics (January 2009, Volume 41) has not been published studies in the article "Six new loci associated with body mass index highlight a neuronal influence on body weight regulation" which make a considerable adjustment in understanding the influence of central nervous system (CNS) on BMI. Scientists have identified the following loci:

Nano- transport

Scientists have made regular progress towards the creation of nano- transport. The emergence of transport at the nanoscale has long puzzled scientists, because like a new era in the field of technocratic development of mankind. And it promises a truly multi-faceted opportunities:

Science & the Public: IPCC looks to vet, report climate-science better

Major U.S. science organizations aren’t the only ones to realize that the climate-science community has bungled � and badly � its portrayals of research on global change in recent months, if not years, and its responses to criticisms. Yesterday, the Intergovernmental Panel on Climate Change (a group established by the United Nations and World Meteorological Organization) said: “we recognize the criticism that has been leveled at us and the need to respond.” So will be convening an “independent review” panel to investigate what the organization’s procedures should be to vet not only the data it uses and how to synthesize conclusions based on those data, but also how it should convey those conclusions (and any necessary caveats) in reports to the public and policymakers.

Science & the Public: Climate science: Credibility at risk, scientists say

Publication of hacked emails exchanged by climate scientists. News accounts of problems in vetting data used in climate-assessment reports. Charges by critics that scientists won’t release their raw data so that others might independently vet published analyses of climate trends. Taken together, these events have marred the reputations of climate scientists, the Intergovernmental Panel on Climate Change and perhaps science generally. Or so concluded a distinguished panel of science luminaries.
