The ebola virus is one of the nastiest pathogens known to man. It corrodes blood vessels and stops clotting, leaving most of its human victims bleeding to death through their pores. And guinea pigs — along with opossums, wallabies and insect-eating bats — have it in their genes.
A genomic hun... Read More
I wouldn't recommend anyone wear the same pair of underwear for a full month without washing them; the results would not be pretty. But a new type of nanotechnology-infused underwear that are quick-drying and odor-absorbing? Well, if they're good enough for astronauts, they should be good enough... Read More
A group of investigators at the Rensselaer Polytechnic Institute (RPI) recently managed a significant breakthrough in their studies of the dangerous bacteria Vibrio cholerae. The bacterium is the agent that causes the terrible infectious disease known as cholera, but the team believes that this ... Read More
Often causing no symptoms in carriers of the disease, worldwide tuberculosis (TB) infects eight to ten million people every year, kills two million, and it is highly contagious as it is spread through coughing and sneezing. "It's a global health disaster waiting to happen, even here in Canada, b... Read More
Public immunization efforts may be much more sensitive than previously realized to small changes in the perceived costs or risks of vaccination, scientists at Harvard University report this week. In some cases, the spread of vaccine avoidance via social networks can make the difference between a... Read More
Health authorities in El Salvador issued a flu epidemic alert, with an average of 14 000 cases a day, exceeding those of dengue fever. Health Minister Maria Isabel Rodriguez told local media that 11 of the 14 departments of the country are the worst affected by respiratory disease.
According ... Read More
Bacteria can elaborate complex patterns of development that are dictated by temporally ordered patterns of gene expression, typically under the control of a master regulatory pathway. For some processes, such as biofilm development, regulators that initiate the process have been identified but s... Read More
To take full advantage of recent increased financial commitments from some governments, international agencies, and philanthropies, accurate and up-to-date mapping of neglected tropical diseases (NTDs) needs to be implemented to help improve the precision of decision-making in NTD control and el...

Every day, millions of microorganisms reach Spain from the Sahara Desert and the Sahel region – by flying. Louis Pasteur demonstrated back in 1861 that germs can move through the air, but it was only recently discovered that bacteria, funguses and viruses can travel thousands of kilometers stuck...

The Department of Health here has cautioned villagers to be vigilant against dengue fever amid a reported 6 deaths during the 1st months of the year . The reported dengue deaths from January to June this year is higher than the 5 recorded during the same period in 2009. The dengue deaths ... Read More
Current methods of diagnosing an infectious disease can take days to weeks. Now a Cambridge, MA-based startup called Pathogenica is developing a way to do it within a day--by reading the DNA sequence of pathogens.
Pathogenica is developing diagnostic tests designed to detect harmful microorga... Read More
In biology and genetics, the concept of epistasis is what gives rise to the whole being more (or less) than the sum of its parts. The quantitative effect of a given mutation upon the traits of an organism has the potential to depend strongly upon the gene versions present in other parts of the g... Read More
Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules.
Using electric fields, the tiny DNA strands are pushed through nanoscale-sized, atomically thin pores in a graphene nanopore platform that ultimatel... Read More
It is widely accepted that the shift in case-fatality rate between waves during the 1918 influenza pandemic was due to a genetic change in the virus. In animal models, the infectious dose of influenza A virus was associated to the severity of disease which lead us to propose a new ... Read More
Buruli ulcer is an infectious disease afflicting thousands of children every year. The difficult-to-cure disease, which is caused by bacteria, occurs in tropical or subtropical climate zones and results in open sores and deformities. For the last two years, the international research consortium ... Read More
Hikers may be locked out of hundreds of caves and 30 000 abandoned
mines in the West and Midwest in a government plan to protect bats
The cave closings may come within the week, said Forest Service
spokeswoman Janelle Smith, and are the latest efforts to combat a
disease... Read More
First, you may be asking yourself – Why viral bioinformatics? Good question! Although it’s true that much in the world of bioinformatics can be applied to all manner of protein and DNA sequences, there are a number of resources that are specific for viruses and there are a number of analyses tha...

One of my big headaches at the moment is a patient — call him Ralph — who appears to be one of the most successful small-time alchemists in all of New York.
He creates gold from dross modern-style, filling his prescriptions every month like clockwork and then selling the unopened bottles for... Read More
A team of scientists, led by Mauro Delogu, virologist from the Veterinary Faculty of the Bologna University and researchers from the Istituto Superiore di Sanità, Istituto Zooprofilattico Sperimentale della Lombardia e dell'Emilia and St. Jude Children's Research Hospital (Memphis, Tennessee) ha...
