Roller coaster geese: Insights into high altitude bird flight physiology and biomechanics

Posted: Published on January 15th, 2015

How bar-headed geese cope with flying in relatively low-density mountain atmosphere as they migrate across the Tibetan Plateau and Himalaya Mountains Roller Coaster migratory flights of geese give unique insights into bird physiology and biomechanics at high altitudes. An international team of scientists studying the migratory biology of bar-headed geese (Anser indicus), during their high altitude flights across the Tibetan plateau and Himalayan Mountains, have revealed how these birds cope with flying in the relatively low-density mountain atmosphere. Dr. Charles Bishop of Bangor University led the study, along with colleagues Robin Spivey and Dr. Lucy Hawkes (now at University of Exeter), Professor Pat Butler from the University of Birmingham, Dr. Nyambayar Batbayar (Wildlife Science and Conservation Center of Mongolia), Dr. Graham Scott (McMaster University) and an international team from Canada, Australia, Germany and the USA. The study used custom-designed data loggers to monitor pressure-derived altitude, body accelerations and heart rate of geese during their southern migration from their breeding grounds in Mongolia to their wintering grounds in South-eastern Tibet or India. Historically, it was commonly assumed that bar-headed geese would fly to high altitudes relatively easily and then remain there during their flights, possibly benefitting from a tailwind. Instead, the … Continue reading →

Estimating the best time of year for malaria interventions in Africa

Posted: Published on January 15th, 2015

New methods for analysing malaria transmission can estimate the best time of year to carry out campaigns such as mass drug treatment and spraying of houses with insecticide. In a study publishing this week in PLOS Computational Biology, Jamie Griffin of Imperial College London uses methods that calculate the effect of interventions against infectious diseases when conditions change seasonally. The study finds that for malaria in Africa the best time of year for mass drug administration is in the low season, whereas the best time for house spraying, or a vaccine that reduces infection rates, is just before the high season. An important summary of the dynamics of an infectious disease is the reproduction number, defined as the average number of secondary infections that would result from each infection if everyone were susceptible. The study's author shows how to find the reproduction number, and the number's change due to interventions when the disease has seasonal variation or the intervention effects change over time. It has been estimated that in some parts of Africa the reproduction number needs to be reduced over 1000-fold in order to locally eliminate malaria. The results of this study can help us to understand how to … Continue reading →

Anatomy of a malapropism

Posted: Published on January 15th, 2015

Let us now praise Mrs. Malaprop. A character in Richard Brinsley Sheridans 1775 play The Rivals, shes made audiences laugh with her almost-but-not-quite-right word choices for generations. Other playwrights have worked this comic vein notably Molire, and Shakespeare, whose constable Dogberry, in Much Ado About Nothing, was a sort of proto-Barney Fife. But today we call such bungled usages malapropisms. Reviewing some examples of these the other day, though, I began to have a little sympathy for their namesake and all the rest of us who occasionally pick the wrong one of a pair of troublesome words. A number of these pairs sound just enough alike and share some common element of meaning to be plausibly confused. Take flaunt and flout, for instance. Flaunt means to show (something) off: a new car, for instance. Flout means to show or express disdain for something: regulations that tell you where you can or cannot park that new car, for instance. Their meanings are distinct: One refers to behavior that arguably pushes the line, the other to behavior that is clearly over the line. But the two sound similar. And they share a common thread of brazenness, cheekiness. No wonder people confuse them. … Continue reading →

An anatomy of diplomacy

Posted: Published on January 15th, 2015

WHAT DIPLOMATS DO: THE LIFE AND WORK OF DIPLOMATS Brian Barder Rowman & Littlefield, 2014 232 + xii pages; price not indicated Sir Brian Barder portrays the working life of British diplomats through the experiences of a fictitious Adam, from the selection process at entry into the Foreign and Commonwealth Office to his retirement. This is divided into chapters matching Adam's jobs. The narrative of Eve, his life partner, is interwoven into it. What might have been a work of realist fiction is leavened with doses of real life; the author's personal experiences presented as examples in each chapter. The style is chatty and personal, with wry humour and an absence of posturing. We obtain intimate insight into the functioning of the British diplomatic service in its professional, societal and human dimensions. This novel approach produces both an engaging narrative for the general reader, and a textbook. Let me highlight the book's striking elements from an Indian perspective, juxtaposing the United Kingdom's methods with our own. The selection process in the United Kingdom (and in other major countries) is handled by the foreign ministry, and is rigorous. The interview in London stretches over two days, and takes each group of … Continue reading →

Stem Cells Symptoms, Causes, Treatment – Why is there …

Posted: Published on January 15th, 2015

Why is there controversy surrounding the use of stem cells? Embryonic stem cells and embryonic stem cell lines have received much public attention concerning the ethics of their use or non-use. Clearly, there is hope that a large number of treatment advances could occur as a result of growing and differentiating these embryonic stem cells in the laboratory. It is equally clear that each embryonic stem cell line has been derived from a human embryo created through in-vitro fertilization (IVF) or through cloning technologies, with all the attendant ethical, religious, and philosophical problems, depending upon one's perspective. Routine use of stem cells in therapy has been limited to blood-forming stem cells (hematopoietic stem cells) derived from bone marrow, peripheral blood, or umbilical cord blood. Bone marrow transplantation is the most familiar form of stem cell therapy and the only instance of stem cell therapy in common use. It is used to treat cancers of the blood cells (leukemias) and other disorders of the blood and bone marrow. In bone marrow transplantation, the patient's existing white blood cells and bone marrow are destroyed usingchemotherapy and radiation therapy. Then, a sample of bone marrow (containing stem cells) from a healthy, immunologically matched … Continue reading →

Stem Cells: Get Facts on Uses, Types, and Therapies

Posted: Published on January 15th, 2015

Stem cell facts Stem cells are primitive cells that have the potential to differentiate, or develop into, a variety of specific cell types. There are different types of stem cells based upon their origin and ability to differentiate. Bone marrow transplantation is an example of a stem cell therapy that is in widespread use. Research is underway to determine whether stem cell therapy may be useful in treating a wide variety of conditions, including diabetes, heart disease, Parkinson's disease, and spinal cord injury. What are stem cells? Stem cells are cells that have the potential to develop into many different or specialized cell types. Stem cells can be thought of as primitive, "unspecialized" cells that are able to divide and become specialized cells of the body such as liver cells, muscle cells, blood cells, and other cells with specific functions. Stem cells are referred to as "undifferentiated" cells because they have not yet committed to a developmental path that will form a specific tissue or organ. The process of changing into a specific cell type is known as differentiation. In some areas of the body, stem cells divide regularly to renew and repair the existing tissue. The bone marrow and … Continue reading →

Eczema woes not just skin deep

Posted: Published on January 15th, 2015

Skin disease takes emotional toll like chronic pain Hard to exercise because sweat triggers itch Diabetes, high blood pressure and insomnia add to eczema health woes Physicians need to treat cardiovascular risks as well as the itch CHICAGO --- Eczema wreaks havoc on its sufferers' lives with health problems that are more than skin deep. Adults who have eczema -- a chronic itchy skin disease that often starts in childhood -- have higher rates of smoking, drinking alcoholic beverages and obesity and are less likely to exercise than adults who don't have the disease, reports a new Northwestern Medicine study. These behaviors give them a higher risk of cardiovascular disease, including high blood pressure and high cholesterol as well as diabetes. They also have higher rates of insomnia. About 10 percent of adults in the U.S. have eczema. "This disease takes a huge emotional toll on its sufferers, like chronic pain," said lead study author Dr. Jonathan Silverberg. "Because eczema often starts in early childhood, people are affected all through their developmental years and adolescence. It hurts their self-esteem and identity. That's part of why we see all these negative behaviors." Silverberg is an assistant professor of dermatology at Northwestern … Continue reading →
