sea turtles have magnetic sense for Longitude
Archives: sea turtle in the ocean Masterpiece of a magnetic sense to use for longitude.
As Kenneth Lohmann and Nathan Putman of the University of North Carolina currently in the journal Current Biology reports, there is probably the most difficult part of navigating the open sea in the determination of longitude and the respective east-west position.
"sailors have required centuries to figure out how to determine the long-term ocean voyages of longitude. Our study shows for the first time how an animal this is accomplished" Monday, February 28, 2011

so Putman.
, it seems, perceive the sea turtles from place to place varying magnetic signatures to determine by their respective position in the room and set off automatically in the right direction. It is already known to use that some animals, including sea turtles, magnetic signals for the determination of latitudes can, but this ability was considered for the determination of longitude so far not advantageous.

According to researchers is the ability the turtles in the fact justified that the animals perceive not only a feature of the earth's magnetic field, but a combination of two properties: the inclination angle of the Earth's magnetic field to the horizontal, the so-called inclination and the strength of the geomagnetic field.
"Near the equator the magnetic field lines run almost parallel to the surface," explain , Putman and Lohmann. If one moves from the equator to the north, also increase the angle of the field lines to become steeper, the closer one approaches the pole, where they are then directed almost at right angles down into the earth. (...) The strength of the magnetic field varies here is usually in the vicinity of the pole near the equator and most weakest. Both parameters seem to vary from north to south, much more constant than from east to west. For this reason, until now, most scientists also suspected that the Earth's magnetic field can be used only useful for production of latitude information.
"The fact that loggerhead turtles can exercise both parameters means that the animals can obtain more information from the Earth's magnetic field originally known as"
so Putman. The combination of slight variations of inclination and magnetic field strength there are therefore unique signatures for individual places on the earth's surface as they know the animals and adopt them can. Their discovery was made by the researchers in studies of newly hatched sea turtles, as they are the animals two simulated magnetic field signatures of two places at the beginning and end of their migration route by the Atlantic Ocean, placed in a round basin, exposing. Both simulated magnetic location markers had the same latitude but different longitudes.
the animals were exposed to the field, as it corresponded to a location on the western side of the Atlantic near Puerto Rico, then swam diese in Richtung Nordosten. Wurden die Meeresschildkröten dem Feld entsprechend eines Ortes auf der östlichen Seite des Atlantiks in der Näher der Kapverdischen Inseln ausgesetzt, schwammen die Tier gen Südwesten.
"Die Ergebnisse unserer Untersuchungen lösen ein altes Mysterium des Verhaltens der Tiere, wie sie aber auch von Bedeutung für den Schutz der Meeresschildkröten haben können" , so Lohman. "Je mehr wir über die Sensorik der Meeresschildkröten auf ihrer Wanderschaft wissen, desto besser können wir auch ihre Wanderwege schützen."
Auch für die Entwicklung neuer Navigationstechnologien könnten die Erkenntnisse der Forscher eine wichtige Role-play. MORE NEWS ON

reconstruction: scientists give Ötzi a new face
3D-reconstruction of the Iceman
Bolzano in the "Iceman", dated 1 March 2011 to 15 January 2012, the special exhibition "Ötzi20. To the opening presents the South Tyrol Museum of Archaeology, among other things, the new life-like reconstruction of Ötzi.
The new naturalistic reconstruction of the Iceman by the Netherlands Adrie and Alfons Kennis brothers based on anatomical 3D images of the head of the glacier's. This now meets the visitors of the museum and embossed image and idea of a Stone Age people who live here, "There Ötzi our history - in the truest sense of the word - a face, touched and fascinated people from around the world, "said the curator.

saw Two decades ago, the discovery and rescue a man from the Bronze Age along with clothing and equipment has survived intact in a glacier in the Ötztal Alps 5300 years of international attention. "Beyond his death holds Ötzi, the Iceman, the people always new insights about his life and his death in thrall. More than 3 million people Ötzi have been visiting the museum, many researchers have studied it, "says the museum (
iceman.it )
detailed view of the facial reconstruction of Ötzi "Fiction" and "reality" and cover the entire range of Ötzi's discovery, his life circumstances, the research, the media reality and fiction, and questions have arisen about Ötzi around. Interactive stations and the use of films, interviews and hands-on guarantee an exciting and entertaining knowledge.
about the scientific aspect, to the special exhibition Ötzi first question: What is an image created of him? What role did the media? Phenomena which have developed around Iceman and excesses to which the whole thing has done? The answers to these questions can the visitors and visitors approach piece by piece, the man from the ice. Throughout the year, moreover, a Ötzi20 ongoing scientific discoveries and new approaches in the exhibition, a discussion. Ötzi the phenomenon is presented in the exhibition from the perspective of artists and artists inside, which have in many different disciplines and techniques dealt with Ötzi.

Space Telescope to analyze exoplanetary atmospheres in the final of ESA's mission for 2020
artists impression of habitable exoplanets (Illu.) to be as it should already start 2020th One of the four finalists' projects is a space telescope with which to analyze the atmospheres of distant exoplanets. The instrument would be the first, could also be determined by whether an exoplanet of examined life can accommodate by Earth standards.
The "exoplanet Characterization Observatory (ECHO) is competing with the X-ray Observatory" Large Observatory For X-ray Timing "(LOFT) for the investigation of fast-moving and high-energy environments of black holes, neutron stars and pulsars, and for examining X-ray outbursts, the satellite, "Space-Time Explorer and Quantum Equivalence Principle Space Test (STU-Quest), should be intensified with the astrophysical questions and the probe "marco polo-R", taken with the ESA sample on an asteroid and return to be transported to Earth.
With a 1.2 meter by measuring levels is responsible for monitoring the telescope distant exoplanet during their transit from their central stars. This drag the planet passes in front of the "sun disc" of their star, so the telescope is to thereby analyze spectrally the atmospheres of the planets falling star light . ECHO would focus it specifically on the search for biomarkers in the atmosphere far as possible to oder sogar vorhandenes Leben auf den analysierten Planeten hinweisen können.

responsible for influencing are mainly three effects: "Erstens bewirken Gezeiten eine Aufrichtung der planetaren Rotationsachsen gegen die Umlaufbahn auf 90 Grad und das bereits innerhalb weniger Millionen Jahre. Auf der Erde beträgt dieser Winkel dank des Bahndrehimpulses des Erdmonds konstante 23,5 Grad und verursacht unsere Jahreszeiten. Auf erdähnlichen Planeten in der habitablen Zone um massearme Sterne gäbe es demnach keine Jahreszeiten. Das wiederum verursacht enorme Temperaturunterschiede zwischen den Polen und dem Äquator. Sie bewirken extreme Winde und langfristig ein Ausfrieren der Atmosphäre an den Polen und eine Evaporation am Äquator. Als zweiter Effekt tritt, ähnlich wie auf dem Jupitermond Io, welcher von globalem Vulkanismus gekennzeichnet ist, zwischen massearmen Sternen und terrestrischen Planets in the habitable zone, a strong tidal heating on. You can make the planet uninhabitable comprehensive. In addition, tides cause thirdly, that the rotation period of exoplanets in the habitable zone of low-mass star is approaching the long-term orbital period. That is, within a circulation path then there is only a natural rotation of the planet. In this state, only one half of the planet radiated from the star and heat, while the other freezes in eternal darkness. "
The habitable zone, the AIP press release to low-mass star is not at least comfortable, if possible abel not even habitable. So far, low mass stars were regarded as promising Candidates for habitable, planetary companion. "The promising Earth-like planets, which are now found around low-mass stars, among which are already the first candidates in the traditional habitable zone, so they must now be analyzed for tides" , the researchers said. In light of the new factors to Heller, the astronomers have also recently been under investigation as a first habitable exoplanets candidates acclaimed "Gliese 581g" (see links ..., we reported below) again, at least in theory. The result: Place on the planet no more seasons and it is likely that, assuming a circular orbit, the length of a Day on the planet would be identical to the length of a year. The planet thus possessed no liquid surface water and would therefore, at least by Earth standards most likely uninhabitable. "Generally, it looks for life on Earth-like planets in the traditional habitable zone badly from around low-mass stars, if we take into account tides. In search of a second Earth, it seems, we also need to look for issued a second sun ", so Heller.

-11 Washington, USA - After NASA has identified with the space telescope Kepler 54 distant planet candidates orbiting their stars at a distance, as it appears on the surface of the planet with moderate temperatures, liquid water and thus allow Earth-like life (.. .
we reported), were thus sent to the location of these potentially also of intelligent creatures inhabited planet to SETI researchers. These have in fact made immediately on the search for intelligent signals from these possible worlds.
According to Seth Shostak was one at the SETI Institute in Mountain View from the transmission specific positions more than enthusiastic: "This is obviously a fascinating thing," said the chief astronomer over " AOLnews.com . "Even if we knew before, of course, that there are extra-solar planet was always the most important question, how many of this planet, so to speak to Cousins of the Earth is, on what it could to life."

astronomers observe planet formation live
Artist's impression of the movement object (front) around the star T Cha "is surrounded by a split-dust disk
Astronomen-Team die kurzlebige Materienscheibe um einen jungen Stern untersucht, in der gerade ein Planetensystem entsteht. Erstmals konnte dabei nun ein Begleiter nachgewiesen werden, der für eine große Lücke in der Scheibe verantwortlich sein dürfte.

Wie die ESO-Astronomen berichten, müssen weitere Beobachtungen nun zeigen, ob es sich bei dem Begleiter um einen Planeten oder um einen Braunen Zwerg handelt.
"Die Entwicklung von einer solchen Scheibe zu einem ausgewachsenen Planetensystem geht allerdings vergleichsweise schnell vonstatten, so dass man nur sehr wenige Objekte in dieser Entwicklungsphase kennt." www.grenzwissenschaft-aktuell.de + + +

Eines dieser Objekte ist der lichtschwache, sonnenähnliche Stern "T Chamaeleontis" (abgekürzt "T Cha"), im Sternbild Chamaeleon am Südhimmel, 330 Lichtjahre von der Erde entfernt. "T Cha" befindet sich mit gerade seinen sieben Millionen Jahren gerade erst am Beginning of his life (for comparison, the sun is about 4.7 billion years old). While known in more developed slices already in the nascent planets, these could be in such "protoplanetary disks" around young stars have not yet observed. "Previous studies show that could be 'T Cha' a worthwhile goal to investigate if you will, how planetary systems arise" , noted Johan Olofsson at the Max-Planck-Institute for Astronomy in Heidelberg. He is one of the first authors of two papers in the journal Astronomy & Astrophysics, describing the new results. "However, T Cha relatively far away from us. Therefore, we need powerful tools such as the 'Very Large Telescope Interferometer' (VLTI), to be able to resolve to prove the details and what is happening in the dust disk in front of him. " These observations were the astronomers, that a formed part of the disk material, a thin dust ring at a distance of only 20 million kilometers from the star has. Behind this inner part of the disk, they discovered an area that is free of dust. The outer part of the disk starts at a distance of about 1, 1 billion kilometers from the star.

Nuria Huelamo from the English "Centro de Astrobiología" and the "European Space Astronomy Centre (ESAC), the first author of the second publication, reports on how it went: " The gap in the dust disk around 'T Cha' was for us a clear indication . Obviously, we had first observed directly, as a companion of the star digs in the protoplanetary disk a trail. "
After evaluation the data the astronomers found indeed a clear signal of an object in the gap of the disk, near the outer edge of the disk at a distance of about a billion miles from the star - equivalent to just over the distance of Jupiter from the sun.
This is the first direct detection of an object is much smaller than a star and is in a gap in the protoplanetary disk of dust around a young star. The astronomers also found evidence that may be of a normal companion star, but it is either a brown dwarf surrounded by dust, or a planet that is just has not formed. Especially the latter scenario would be of particular interest to astronomers.
Further observations are now to help determine whether it is actually a planet is formed and also clarify the question of where the dust in the inner region of the disk is.
Just days before the announcement of the observation of ESO astronomers have colleagues from the Max-Planck-Institute for Astronomy (MPIA), similar to the observations also only a few million year young star "LKCA 15" and the star " AB Aur described (... we reported )

our daily newsletter order + + + Asthma is one of Europe on the major chronic diseases, childhood, and asthma sufferers often suffer a lifetime from their disease. why does asthma have a special social and public health relevance. is caused the disease through a combination of genetic and environmental factors, wobei verschiedene Studien der letzten Jahre ergaben, dass Bauernkinder ein deutlich niedrigeres Asthmarisiko haben als andere Kinder. Um der Ursache dieses Phänomens auf den Grund zu gehen, untersuchten die LMU-Forscher nun Schulkinder in Bayern. Im Rahmen der beiden großen europäischen Epidemiologiestudien GABRIEL und der PARSIFAL verglichen Ege und seine Kollegen Kinder, die auf einem Bauernhof lebten, mit anderen Kindern aus denselben ländlichen Regionen, die allerdings nicht auf einem Bauernhof lebten.
Das Besondere an der neuen Untersuchung: Die Wissenschaftler beschränkten sich auf Innenräume und untersuchten den Staub aus den Kinderzimmern auf Pilze und bakterielle DNA. Im Ergebnis zeigte sich, dass sich deal peasant children in indoor environment with a lot more different microbes need than other children. Here, the nuclei appeared as a kind of environmental health monitors: The more diverse the Mikrozoo in house dust was, the lower was the risk of asthma. How these bacteria reduce the risk of asthma is still unclear. Scientists hold different explanations for conceivable. "One possibility would be that the combination of certain environmental bacteria stimulate the innate immune system and asthma favorable immune situation is prevented by"
said Ege. Another explanation could be that the discussion of various environmental microorganisms excessive colonization of the lower airways with asthma-causing germs to prevent - as in the intestine that required for a smooth function, a balanced microbial flora.
said Ege. Another explanation could be that the discussion of various environmental microorganisms excessive colonization of the lower airways with asthma-causing germs to prevent - as in the intestine that required for a smooth function, a balanced microbial flora.
Microbial diversity alone, however, probably not enough to prevent asthma. It's probably a combination of specific species that can exert a protective effect. "In the whole investigated range, there were some seeds that could be particularly valuable," said Ege, "including non-specific bacilli and staphylococci - about the nature of Staphylococcus sciuri -. And molds of the genus Eurotium" The next challenge for the Scientists now is to investigate the association between the presence of microbes in house dust and the species-specific protection against asthma - and to find the long run among the candidates the germs that are eligible for a potential vaccine.

"The world's dramatic increase in the use of mobile phones has many concerns about possible harmful effects of electromagnetic fields modulated at high frequency (radio frequency-modulated electromagnetic fields, RF-EMFs can arise) "
, explain the authors of the study. " Of particular concern are potential carcinogenic effects as a result of RF-EMF emissions from mobile phones. The results of different epidemiological studies on possible links between the use of mobile phones and increase in brain have yet been contradictory and the question remains open. " This very fact nevertheless has the need for studies on the effects of RF EMFs through the use of mobile phones on brain function of people are.

this, the researchers placed at random in 47 subjects for 50 minutes active mobile phones on either the right or left side of the head and monitored the brain activity after injection of fluorodeoxyglucose (with the glucose metabolism in the brain can be measured) using the imaging technique of positron emission tomography (PET).
Although the result showed in the overall picture of brain activity, no statistically significant changes but one of around seven per cent and thus significantly increased glucose metabolism was determined in those directly exposed to the mobile regions of the brain, such as on the opposite side of the head and therefore not used during the call could not be detected. Actually voted, this increase also in line with the previously calculated expected values and thus under the influence of electromagnetic fields.

Further studies on biomarkers for functional brain changes caused by the exposure to RF radiation are absolutely appropriate here. "

In the editorial of the current JAMA issue comment on the other hand, the physicians, Dr. Henry Lai of the University of Washington "and Dr. Lennart Hardell of the" University Hospital in Orebro Sweden specifically on the results of the study: "Although possible biological consequences of increased glucose metabolism through intensive use of mobile phones remains unknown and further investigation is necessary, there is the urgent question of whether an intensive use of mobile phones with stronger results than those applied in the study, radiation energy and to a chronically increased glucose metabolism. Possible intensive and chronic health effects must be verified and it is a lot of work in order to understand these implications. "
