New research helps explain why bird flu has not caused a pandemic
Bird flu viruses would have to make at least two simultaneous genetic mutations before they could be transmitted readily from human to human, according to research published today in PLoS ONE. view more (2009-11-19)
New insight into predicting cholera epidemics in the Bengal Delta
Cholera, an acute diarrheal disease caused by the bacterium Vibrio cholerae, has reemerged as a global killer. Outbreaks typically occur once a year in Africa and Latin America. But in Bangladesh the epidemics occur twice a year - in the spring and again in the fall. view more (2009-11-05)
Earlier flu viruses provided some immunity to current H1N1 influenza, study shows
University of California, Davis, researchers studying the 2009 H1N1 influenza virus, formerly referred to as "swine flu," have identified a group of immunologically important sites on the virus that are also present in seasonal flu viruses that have been circulating for years. view more (2009-10-15)
Archaeopteryx was not very bird-like
New research published this week clips the wings of Archaeopteryx. First found in Germany in the 1860's and dating to 150 million years ago, Archaeopteryx has long been considered the iconic first bird. view more (2009-10-09)
Inside the first bird, surprising signs of a dinosaur
The raptor-like Archaeopteryx has long been viewed as the archetypal first bird, but new research reveals that it was actually a lot less "bird-like" than scientists had believed. view more (2009-10-09)
Designing probiotics that ambush gut pathogens
Researchers in Australia are developing diversionary tactics to fool disease-causing bacteria in the gut. view more (2009-09-08)
H1N1 Pandemic Virus Does Not Mutate Into 'Superbug' in UMd. Lab Study
A laboratory study by University of Maryland researchers suggests that some of the worst fears about a virulent H1N1 pandemic flu season may not be realized this year, but does demonstrate the heightened communicability of the virus. view more (2009-09-01)
Bird flu leaves the nest -- adapting to a new host
Current research suggests that viral polymerase may provide a new therapeutic target for host-adapted avian influenza. view more (2009-08-27)
The tourist trap
Mosquitoes with the potential to carry diseases lethal to many unique species of Galapagos wildlife are being regularly introduced to the islands via aircraft, according to new research published today. view more (2009-08-12)
Avian influenza strain primes brain for Parkinson's disease
At least one strain of the H5N1 avian influenza virus leaves survivors at significantly increased risk for Parkinson's disease and possibly other neurological problems later in life. view more (2009-08-11)
Mapping the crocodile genome
The first ever genetic linkage map for a non-avian member of the Class Reptilia has been developed. Researchers writing in the open access journal BMC Genomics have constructed a first-generation genetic linkage map for the saltwater crocodile Crocodylus porosus. view more (2009-07-29)
Simple measures may prevent transmission of stomach ulcer bacteria
The stomach ulcer bacterium Helicobacter pylori is not transmitted through drinking water as previously thought, but rather through vomit and possibly faeces. view more (2009-06-25)
Study: Indirect transmission can trigger influenza outbreaks in birds
New data on the persistence of avian influenza viruses in the environment has allowed a team of University of Georgia researchers to create the first model that takes into account both direct and indirect transmission of the viruses among birds. view more (2009-06-03)
Jeepers Creepers! Climate Change Threatens Endangered Honeycreepers
As climate change causes temperatures to increase in Hawaii's mountains, deadly non-native bird diseases will likely also creep up the mountains, invading most of the last disease-free refuges for honeycreepers - a group of endangered and remarkable birds. view more (2009-05-27)
New 3-D structural model of critical H1N1 protein developed
In just two weeks from the time the first patient virus samples were made available, Singapore scientists report an evolutionary analysis of a critical protein produced by the 2009 H1N1 influenza A virus strain. view more (2009-05-26)
The challenges of avian influenza virus: Mechanism, epidemiology and control
The latest special issue of Science in China Series C: Life Sciences focuses on the recent progress in the H5N1-related research field. view more (2009-05-22)
Veterinarians at high risk for viral, bacterial infections from animals
The recent H1N1 influenza epidemic has raised many questions about how animal viruses move to human populations. view more (2009-05-15)
Human nose too cold for bird flu, says new study
Avian influenza viruses do not thrive in humans because the temperature inside a person's nose is too low, according to research published today in the journal PLoS Pathogens. view more (2009-05-15)
Does new swine flu virus kill by causing a 'cytokine storm'?
The swine flu outbreak that began in Mexico and continues to spread around the globe may be particularly dangerous for young, otherwise healthy adults because it contains genetic components of the H5N1 avian influenza virus, which can induce a "cytokine storm," in which a patient's hyper-activated immune system causes potentially fatal... view more...

Avian Flu Research Sheds Light on Swine Flu Outbreak
A recent study by University of Maryland researchers examines the mechanisms underlying transmission of combined avian-human viruses and illustrates how virus outbreaks like that of the current swine flu come about. view more (2009-04-30)
