What Happened on Easter Island? @ the London `Catastrophes` conference
Easter Island is exceptionally isolated in the South Pacific. When Europeans first visited the island in 1722 AD, they found a population of about 4000 Polynesians scratching a living among what appeared to be the ruins of a collapsed civilization. Stone figures weighing up to 80 tonnes littered the landscape and there were also numerous... view more... (2002-08-17)

Researchers at the University of California, San Francisco, have identified a virus behind the mysterious infectious disease that has been killing parrots and exotic birds for more than 30 years.   view more (2008-07-30)

From frog skin to human colon: rapid responses to steroid hormones
New research on steroid hormone action in the human colon and kidney could pave the way for novel therapeutic targets for the treatment of hypertension and diarrhoea. Prof Brian Harvey at University College Cork has been studying how the hormones oestrogen and aldosterone produce rapid changes in the transport of salt and water through human... view more...

Smiths Detection to launch a portable diagnostic system for foot-and-mouth disease and avian flu
Smiths Detection, part of the global technology business Smiths Group, today announces it is to launch a portable detection system that will enable veterinarians to carry out on-site diagnosis of animal diseases such as foot-and-mouth and avian flu.   view more (2007-10-15)

Study shows endemic cholera can be controlled with oral vaccines
Endemic cholera, a potentially fatal diarrheal disease found in the world's most impoverished countries, could be effectively controlled by orally vaccinating half of the affected populations once every two years for only pennies per dose.   view more (2007-11-27)

Arbor Vita rapid H5N1 flu diagnostic presented at ICEID meeting
Preliminary research from the Department of Respiratory Disease Research at the Naval Health Research Center (NHRC) suggests that a rapid antigen assay test developed by Arbor Vita Corporation (AVC) shows promise as a useful diagnostic for the detection of the avian influenza virus in humans. Researchers from NHRC reported their findings last week... view more... (2008-03-28)

Avian flu becoming more resistant to antiviral drugs, says University of Colorado study
A new University of Colorado at Boulder study shows the resistance of the avian flu virus to a major class of antiviral drugs is increasing through positive evolutionary selection, with researchers documenting the trend in more than 30 percent of the samples tested.   view more (2009-01-08)

Targets identified for new cholera, diphtheria and typhoid drugs
Scientists from the University of Birmingham have identified dozens of new target proteins thought to be involved in the disease causing process in a range of bacterial infections. These proteins could make excellent targets for new treatments or vaccines against infections including cholera, diphtheria and typhoid, reports Professor Mark Pallen... view more... (2001-08-30)

Microbial stowaways: Are ships spreading disease?
Ships are inadvertently carrying trillions of stowaways in the water held in their ballast tanks. When the water is pumped out, invasive species could be released into new environments. Disease-causing microbes could also be released, posing a risk to public health, according to an article in the May issue of Microbiology Today.   view more (2008-05-29)

New study supports action to tackle poor sanitation in developing countries
Improvements in sanitation and sewerage systems can have a dramatic effect on reducing cholera and other diarrhoeal diseases, research has shown.   view more (2007-11-09)

Big-brained animals evolve faster
Ever since Darwin, evolutionary biologists have wondered why some lineages have diversified more than others. A classical explanation is that a higher rate of diversification reflects increased ecological opportunities that led to a rapid adaptive radiation of a clade.   view more (2008-08-15)

Avian flu threat: New approach needed
As the first globally co-ordinated plan for the planet's gravest health threats is hatched by government ministers from around the world this weekend, a new report sets out a 10-point plan for this new, globalised approach to infectious diseases such as avian flu.   view more (2008-10-23)

Rainfall and river networks prove accurate predictors of fish biodiversity
Princeton researchers have invented a method for turning simple data about rainfall and river networks into accurate assessments of fish biodiversity, allowing better prediction of the effects of climate change and the ecological impact of man-made structures like dams.   view more (2008-05-08)

Signal molecule holds possible key to tumour growth
Immunity to a cancer in chickens could shed light on ways to control certain human cancers according to scientists from the Institute for Animal Health (IAH). Their work on Marek's disease (MD) in chickens has identified the first natural model for specific Hodgkin's and non-Hodgkin's lymphomas, and is published this week in PNAS (06-10 September... view more...

Childhood Mortality In Rural Senegal: A Significant Decline But Danger Of Resurgence Persists
The childhood death rate in sub-Saharan Africa is one of the highest in the world, in spite of a decline observed over the past few decades. This trend had been analysed for short selected periods, but the factors determining it over the long term are poorly known, owing to insufficient data. Demographic surveillance has been conducted in African... view more... (2002-09-27)

Human vision inadequate for research on bird vision
The most attractive male birds attract more females and as a result are most successful in terms of reproduction. This is the starting point of many studies looking for factors that influence sexual selection in birds.   view more (2008-05-13)

Climate and Cholera: an increasingly important link
A study by the coordinator of the Research Group on Climate at the Barcelona Science Park, University of Barcelona, Dr Xavier Rod'³, and other researchers at the University of Michigan and the International Center for Diarrhoeal Disease Research in Bangladesh, provides evidence not only that climatic variation associated with the El Ni'ħo-Southern... view more...

Diversity among bird populations found to reduce threat of West Nile virus
A biologist and undergraduate student have discovered that what's good for an area's bird population is also good for people living nearby.   view more (2008-06-25)

Bacterial pathogens and rising temperatures threaten coral health
Coral reefs around the world are in serious trouble from pollution, over-fishing, climate change and more. The last thing they need is an infection. But that's exactly what yellow band disease (YBD) is-a bacterial infection that sickens coral colonies.   view more (2009-01-20)
