Hydraulic fracturing, or “fracking”, is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside. What effect does this process have on the microorganisms that naturally exist in the water in this process?

Plants associated bacteria play a key role in host productivity and health. These bacteria are phylogenetically diverse and form interactions considered neutral, beneficial or detrimental. A better understanding of these interactions will have a direct impact in agriculture by promoting sustaina... Read More
The emergence of human infections with avian influenza viruses (H7N9 and H5N1) have raised concerns about the virus gaining the ability to spread person-to-person, potentially causing a deadly pandemic. So far the number of human cases has been limited but the mortality rates have been high. ... Read More

There is much interest in the role of nutrients and micronutrients in the support of host defense against infections. However, there is controversy in the ability of supplements to help prevent or treat infections. Speakers discuss research on the role of vitamin D supplements to prevent and/or ... Read More
Whether the microorganisms routinely inhabit the upper troposphere -- perhaps living on carbon compounds also found there -- or whether they were simply lofted there from the Earth's surface isn't yet known. Airborne microbes are of interest to atmospheric scientists, because they could play a r... Read More

Almost 1 out of every 3 people in the United States will develop shingles during their lifetime. Despite the approval and recommendation by the FDA of a shingles vaccine for adults over 50, only 16% of American seniors over 60 are vaccinated. Vaccinations are even lower for those aged 50-60. A... Read More
Death is what fungi are all about. By feasting on the deceased remains of almost all organisms on the planet, converting the organic matter back into soil from which new life will spring, they perform perhaps the most vital function in the global food web. Fungi, which thrive on death, make all ... Read More
A green alga with throat- and stomach-like structures can swallow and digest bacteria when deprived of light, further bolstering Lynn Margulis’s widely accepted idea that the origin of the plant-powering chloroplast was a fortuitous bout of indigestion.
Termed “Endosymbiotic Theory“, the idea... Read More
Patients getting medical care can catch serious infections called healthcare-associated infections (HAIs). While most types of HAIs are declining, one -- caused by the bacterium Clostridium difficile --continues to grow. C. difficile causes diarrhea linked to 14,000 American deaths each year. Pa...

During the April 2013 avian influenza A (H7N9) outbreak, more than 130 human infections with H7N9 were reported. Most patients had severe respiratory illness and 44 people have died. Studies suggest that the H7N9 virus has developed resistance to oseltamivir. A human interferon already in use fo... Read More

The disruption of the human microbiome through use of antimicrobials is a topic of growing interest among healthcare epidemiologists, not only because it is a major risk factor for C. difficile infection (CDI), but also because it could be a driving force behind the introduction and proliferatio...

Security concerns at laboratories doing research on infectious diseases mean that most of us will never get a look at the inner workings of such labs, the most secure designated as Biosafety Level 4 (BSL-4). But because its BSL-4 lab is not yet operational, the National Emerging Infectious Disea... Read More
The Rockefeller University's Luciano Marraffini is interested in understanding how bacteria evolve by incorporating DNA sequences from other bacteria or from the environment into their genomes. His research focuses on the mechanisms that control the traffic of DNA molecules between bacteria.

When it comes to the evolution of life on earth, those who have been here longest have seniority. And after four billion years, bacteria reign supreme. Unfortunately for us, some of them have been using that time to ... Read More
