The world population is over seven billion and all of these people need feeding. However, the energy requirement of a species depends not only on numbers but on its average mass. New research published in BioMed Central's open access journal BMC Public Health has estimated the total mass of the human population, defined its distribution by region, and the proportion of this biomass due to the overweight and obesity. Up to half of all food eaten is burned up in physical activity. Increasing...

Older Male Ants Single Out Younger Rivals For Death Squad

Male Cardiocondyla obscurior ants are diphenic (either winged or wingless). New research published in BioMed Central's open access journal BMC Ecology demonstrates that the dominant wingless (ergatoid) male is able to identify potential rivals before they emerge from their pupae. Constant patrolling of the nest ensures that this male is able to bite or chemically tag rivals as soon as they emerge from their pupae. Chemically tagged ants are quickly destroyed by workers. When ants emerge...

It seems that while the practice of bloodletting throughout history had little or no effect on most diseases, and the practice was abandoned in the 19th century, new research published in BioMed Central's open access journal BMC Medicine demonstrates that blood donation has real benefits for obese people with metabolic syndrome. Two sessions of bloodletting were enough to improve blood pressure and markers of cardiovascular disease. Metabolic syndrome is the name given to a host of...

It is important to be able to monitor genetically modified (GM) crops, not only in the field but also during the food processing chain. New research published in BioMed Central's open access journal BMC Biotechnology shows that products from genetically modified crops can be identified at low concentration, using bioluminescent real time reporter (BART) technology and loop mediated isothermal amplification (LAMP). The combination of these techniques was able to recognise 0.1% GM contamination...

Modern methods for mass production of biological agents and fine chemicals require precise control of pH. However within these systems it is not always possible to use traditional methods for measuring acidity and alkalinity. Biomed Central's open access journal BMC Biotechnology describes a new and user friendly method for measuring pH, which uses luminescent dual life-time referencing (DLR), to provide real-time characteristics of enzyme reactions. Industrial methods for manufacturing...

House mice (Mus musculus) happily live wherever there are humans. When populations of humans migrate the mice often travel with them. New research published in BioMed Central's open access journal BMC Evolutionary Biology has used evolutionary techniques on modern day and ancestral mouse mitochondrial DNA to show that the timeline of mouse colonization matches that of Viking invasion. During the Viking age (late 8th to mid 10th century) Vikings from Norway established colonies across...

A new study conducted by Boston University School of Medicine (BUSM) researchers shows that a majority of medical students in Yemen believe that chewing the plant khat is harmful to one's health but they would not advise their patients to quit. The study, which is published online in the journal Substance Abuse, was done by BUSM class of 2013 students Paul Yi, John Kim and Khalil Hussein. Richard Saitz, MD, MPH, professor of medicine and epidemiology at BUSM and a physician specializing in...

Respiratory tract infections, including pneumonia, are the most common cause of death in children under the age of five. In a study looking at children given standard antibiotic therapy, new research published in BioMed Central's open access journal BMC Medicine shows how zinc supplements drastically improved children's chances of surviving the infection. The increase in survival due to zinc (on top of antibiotics) was even greater for HIV infected children. In a double-blind, randomized,...

It can be difficult to distinguish between people with normal age-associated memory loss and those with amnestic mild cognitive impairment (aMCI). However people with aMCI are at a greater risk of developing Alzheimer's disease (AD), and identification of these people would mean that they could begin treatment as early as possible. New research published in BioMed Central's open access journal BMC Geriatrics shows that specific questions, included as part of a questionnaire designed to help...
