The hemagglutinin (HA) and neuraminidase (NA) glycoproteins of the influenza virus particle serve distinct functions during infection. The HA binds sialic acid-containing cellular receptors and mediates fusion of the viral and cell membranes, while the NA removes sialic acids from glycoproteins.... Read More
Two studies published in the December issue of Infection Control and Hospital Epidemiology show antibiotic resistance patterns for children have held stable over a seven-year period and surgical patients in U.S. children's hospitals account for 43 percent of all antibiotic use in children's hosp...

Testing every person in India’s billion-plus population every five years for HIV would not only be cost-effective but also could save millions of lives for decades to come, a new study suggests.
In India most people who are HIV positive don’t know it—even though testing and treatment are rela... Read More
Natural selection favours those with a greater capacity to generate genetic variation.
Some gamblers succeed by spiriting cards up their sleeves, giving them a wider range of hands to play. So do some bacteria, whose great capacity for genetic variability helps them evolve and adapt to rapidl... Read More
Scientists have long believed that microorganisms that produce methane swim toward the hydrogen gas they need to stay alive, but it has been too hard to prove in the lab.
Montana State University researchers have now overcome those challenges, allowing them to verify it for the first time, sa... Read More
We live in a world run by microbes, the vast majority of which we have yet to identify or name. We can only refer to them collectively as the microbial dark matter (MDM). However you define a prokaryotic species, and however you tally them once identified, there is a huge gap between the 12,000 ... Read More
Food transit through the small intestine affects the body's absorption of nutrients and, consequently, our health. The discovery that food transit time is regulated by a hormone indicates new ways to increase the intestinal absorption of nutrients, and thus potentially treat malnutrition.

The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical Atlantic ocean. This runoff forms a freshwater plume, hundreds of miles across, that profoundly affe... Read More

The mosquito-borne infection is cropping up in Florida, but mysteriously not in similar regions in the nation.
Most Americans lose little sleep over dengue fever. The mosquito-borne infection is a leading killer in the tropics and subtropics, but it’s been a long-held belief that ubiquitous a... Read More
Activating a mother’s immune system during her pregnancy disrupts the development of neural cells in the brain of her offspring and damages the cells' ability to transmit signals and communicate with one another, researchers with the UC Davis Center for Neuroscience and Department of Neurology h...

In May 1984, readers of an article by Schwartz and Cantor in the prestigious journal Cell were to stumble upon pictures of DNA agarose gels that were among the lousiest of such ever published after the method was introduced in the early 70s. Why did the editors of Cell risk their reputation? Or ... Read More
Hand washing is thought to be effective for the prevention of transmission of
Diarrhea pathogens. However it is not conclusive that hand washing with soap is more
Effective at reducing contamination with bacteria associated with diarrhea than using water only. Read More
Health officials are still learning from the fungal outbreak tied to tainted steroid pain injections made at the now-shuttered New England Compounding Company.
Researchers now know that most patients' immune systems didn't try to fight off the deadly fungi as it burrowed into their spinal col... Read More
Pick an archaeon, any archaeon, and you will find it has a story to tell. Not all archaea are exotic but plenty of them are. These stalwarts live in environments we humans call extreme, where they carry out what to us seem extreme types of metabolic conversions. Most have come rather late into o... Read More
People living near pig farms or agricultural fields fertilized with pig manure are more likely to become infected with methicillin-resistant Staphylococcus aureus (MRSA) bacteria, according to a paper published today in JAMA Internal Medicine1.
Previous research has found that livestock worke... Read More
A new virus called Pithovirus sibericum has been isolated from 30,000 year old Siberian permafrost. It is the oldest DNA virus of eukaryotes ever isolated, showing that viruses can retain infectivity in nature for very long periods of time. Read More
Some strains of the avian H7N9 influenza that emerged in China this year have developed resistance to the only antiviral drugs available to treat the infection, but testing for antiviral resistance can give misleading results, helping hasten the spread of resistant strains. The authors of a stud... Read More
It's a question we ask about many recently discovered bacteria: What, exactly, do the Verrucomicrobial do in the environment? Since their discovery, representatives of the phylum Verrucomicrobia have been detected in soil and aquatic environments around the world, but we have very few existing i... Read More
