Fungus-farming ants have cultivated the same fungal crops for 50 million years. Each young ant queen carries a bit of fungus garden with her when she flies away to mate and establish a new nest.
Chicago (June 1, 2009) ? The International Serious Adverse Events Consortium (SAEC) announced today initial results from its research designed to discover genetic markers that may predict individuals at risk for serious drug induced liver injury (DILI).
Fallow deer become hoarse when trying to attract a mate, according to scientists from Queen Mary, University of London.
YUMA, AZ--The convenience of fresh-cut produce, which includes packaged lettuces, has greatly increased sales despite multiple foodborne outbreaks associated with these products. To reduce these risks, strict hygiene programs and sanitizers are used for decontamination once the food is harvested. Preventing microbial contamination in the fields is equally important.
A new drug for multiple sclerosis can dramatically reduce the chances of a relapse or a deterioration of the condition, according to a new study from researchers at Queen Mary, University of London.
The study's findings appear to echo the insect worlds portrayed in the animated films Antz and Bee Movie, in which the characters live in rigidly conformist societies.
Scientists from the Universities of Edinburgh and Oxford reached their conclusion by creating a mathematical model to study the manner in which cooperative groups of animals, known as superorganisms, evolve.
MADISON -- The adage that dead men tell no tales has long been disproved by archaeology.
Scientists from Queen Mary, University of London have discovered how changes to a frog's immune system may be the key to beating a viral infection which is devastating frog populations across the UK.
Google "Edward the Confessor" and you'll get page after page of links to biographies of this 11th-century English king, to Westminster Abbey, which he founded and where he is buried, and to the Magna Carta, which was partly inspired by laws enacted during his 24-year reign.
A spectacular new image of an unusual spiral galaxy in the Coma Galaxy Cluster has been created from data taken by the Advanced Camera for Surveys on the NASA/ESA Hubble Space Telescope.
Individual and family attributes may make some adolescents more 'resilient' to the effects of living in a disadvantaged community, according to new research sponsored by the ESRC. How inner city young people feel about their own psychological and social health and the area where they live is influenced by differences in home and social life as well as the physical environment, says a study led by Professor Sarah Curtis, of Queen Mary, University of London.
A genetically unusual population of ants is changing some of the fundamental ways researchers think about insect colonies. Social insects, like ants and bees, thrive on the caste system -- a precise division of duties among colony members. In most of these societies, environment is thought to influence whether larvae develop into queens or sterile female workers, said Steve Rissing, a professor of evolution, ecology and organismal biology at Ohio State University.
It may not matter whether there is a mountain high enough or a river wide enough to keep members of a species apart. New species may diverge and form because of something as fundamental as a call to dine. According to new research by Tigga Kingston, a research associate in the Department of Geography at Boston University, and Stephen Rossiter, a National Environment Research Council research fellow in the School of Biological Sciences at Queen Mary, University of London, geographical barriers may not be necessary for speciation. In their study of one species of bat in Southeast Asia, the scientists found that the bats were diverging into exclusive groups primarily because of acoustic differences in the calls they make to locate the insects they eat.
Using a new technique, researchers have studied the heart rate of unborn babies in minute detail. The technique, reported in this months British Journal of Obstetrics and Gynaecology, will allow doctors to monitor the health of babies' hearts and obtain the full fetal ECG (fECG), particularly during high risk pregnancies, such as where the mother suffers from diabetes or pre-eclampsia or where there is a family history of serious arrhythmia such as Long QT syndrome.
New research has provided the first neuro-imaging evidence that the brain's frontal lobes play a critical role in planning and choosing actions. The research team has found that a small region in the frontal lobe of the human brain is selectively activated when an individual intends to make a particular action and not another. These findings help explain why individuals with frontal lobe damage sometimes act impulsively and often have problems making decisions.
