To prevent epidemics, ants licking each other

(www.neomundo.com.ar)-to heal an infection, ants (or rather, a type of Ant) lick each other.) An Austrian research shows how healthy ants groom companions come into contact with a pathogenic fungus (Metarhizium anisopliae). This social behavior drastically reduces the infection, because it reduces the number of spores of fungi which are reproduced on the surface of the body of each Ant. Experiments were made with four populations of ants and the route of the pathogen continued using fluorescence techniques. After observing the interaction between ants, the scientists measured their immune capacity. Results on memory and the immune ability of this species surprised researchers, as invertebrates do not have the molecular mechanisms of vertebrates needed for immunization. Medical research always interested to understand how agencies are fighting an infection. One of the most common practices consists of testing error and one of the most common remedies, vaccination. The success of this treatment involves exposure of individuals to a controlled number of pathogens to train their immune capacity against the disease. As in the case of social species there is more possibility of contagion because individuals living in community, mass vaccination contributes to the immunity of the group.

Antarctic ice still melting without stopping

. Shortly after its launch the first day of March 2002, Envisat sent images of how 3,200 square kilometres of ice is his in just days due to mechanical instabilities caused by warming in the region. Envisat now shows how the barrier (called Larsen B) lost other 1,790 square kilometres in the last decade. “Ice shelves are very sensitive to changes in temperature or oceans currents and warming of the atmosphere,” explains Helmut Rott of the University of Innsbruck. “The atmospheric temperature North of the Antarctic Peninsula rose about 2.5 Â° C over the past 50 years, rather than the average planetary level, and this is causing the decline and disintegration of ice shelves. The extension of the barrier B Larsen spent 11.512 square kilometres in January 1995 6.664 km in February 2002, after a long series of landslides. After the collapse of March 2002, its length was reduced to 3,463 kilometers. Now, Envisat shows that Larsen B has just 1,670 square kilometers of surface. “The current climate models predict a dramatic warming at high latitudes – detailed Rott-.” “Data collected by Envisat on the Larsen ice shelf confirm the great vulnerability of these platforms, and show the importance of his role in the stabilization of the glaciers that are upstream.” Radar observation satellites of the Earth, such as GRILLING, aboard Envisat, are particularly useful to monitor the polar...

. To those conclusions came an investigation conducted by the National Institute of child health and human development Eunice Kennedy Shriver (United States). Katherine Laughon, epidemiologist in charge of the study, explains that still do not know for sure the cause of this change in the duration, but they believe it is due to the modifications implemented by professionals of health in the delivery room. Researchers compared 40,000 deliveries crystallized in the late 1969 and 100,000 that took place from 2002 to 2008, and found that on average labor lasts 2.6 hours more in first-time mothers. Mothers who already have children the time lasted two hours. Specialists also found that current babies are born five days earlier and tend to weigh more. Today, women also tend to have a greater body mass and four years larger index. â€³Las older women typically have longer than the young delivery jobs. However, even taking into account changes in the maternal age, that doesn’t explain completely the difference in the time that lasts the work of partoâ€³, he argues. Laughon found several differences in medical practices used at the time of delivery. Epidurals is today most often used and administered less oxytocin, the hormone that speeds up labor. â€³Sin the use of this hormone, childbirth may last even longer actualmenteâ€³ says. Research also showed that today are four times more Caesarean sections 50...

They prove that the tratorno deficit of attention and hyperactivity is over diagnosed

(www.neomundo.com.ar)-_Hace_tiempo_se_sospecha_que_el_trastorno_por_dÃ©ficit_de_atenciÃ³n_e_hiperactividad_(TDAH) is over-diagnosed in boys, but now an investigation found evidence supporting this hypothesis. ) Los psychologists Silvia Schneider and JÃ¼rgen Margraf of the Ruhr-UniversitÃ¤t Bochum (Germany) and Katrin BruchmÃ¼ller of the University of Basel (Switzerland) conducted a research which shows how psychologists and psychiatrists who made diagnoses are based on unclear rather than adhere to the established medical approach rules. Specialists, which published its findings in the Journal of Consulting and Clinical Psychology Journal, claim that over-diagnosis is more common in boys than in girls. Schneider and BruchmÃ¼ller put much emphasis on highlighting what they qualify as “little research designed to elucidate the effectiveness of diagnosis” of ADHD. â€³A despite the strong interest public, only a few empirical studies focused on this temaâ€³, they claim. In their new research, they worked with 473 psychologists or psychiatrists, among other things, involved to diagnose possible ADHD cases. Specialists put together four cases for volunteers diagnosticaran. In one case was fulfilled the diagnostic criteria for diagnosing TDHA but the rest not, and participants were aware of the sex of the patient. Schneider, Margraf and BruchmÃ¼ller noted that psychologists and psychiatrists diagnosed with many cases of this pathology when it did not meet the criterion, and this error was much more common with male patients. According to Schneider, Margraf and BruchmÃ¼ller, many of the volunteers based his diagnosis on typical symptoms such...

USA: Linking obesity during pregnancy with autism

General |

CHICAGO (AP) – obesity may be a factor that increases the risk for a pregnant woman to have a child with autism, reports a study dfifundido on Monday in the digital publication Pediatrics. Document is among the first linking both aspects and although it is not proven that obesity causes autism, the authors claim that the results raise public health concerns due to the high number of women increases weight in United States. Obese pregnant women are 67% more likely than normal weight to have autistic children, according to the study. Pregnant women with excess weight also faced double the risk of having children with other developmental delays. The study was conducted among some 1,000 children of California, whose ages were between two and five years. Almost 700 children had autism or other underdeveloped, and 315 did not have these problems. On average, women have one between 88 chances of having a child with autism. By their results, the study suggests that obesity during pregnancy increases that risk, one among 53 possibilities, noted the authors. Since more than one third of the women in United States of childbearing age are obese, the results of the study are potentially worrying and represent an incentive to keep them a normal weight, said researcher Paula Krakowiak, co-author of the paper and the University of California, Davis researcher. Various previous studies have linked...
