The exact number of bacteria living in or on humans isn't known, though it is estimated to be around a trillion. In any case, the number of microbial cells in the human body outnumbers the human ones by a factor of 10. Those symbiotic microbes endow humans with otherwise unattainable metabolic c... Read More
In a major scientific breakthrough, scientists of the School of Biotechnology, Banaras Hindu University, have isolated a group of
bacteria that degrades lignite coal (low energy producing coal) to produce methane gas for increased fuel efficiency.
While the isolation of the special group of... Read More
Americans Elizabeth H. Blackburn, Carol W. Greider and Jack W. Szostak won the 2009 Nobel Prize in medicine on Monday for discovering a key mechanism in the genetic operations of cells, an insight that has inspired new lines of research into cancer.

A pathogen is a an organism (bacterium, virus, parasite) that causes disease in another organism. According to data from the U.S. Centers for Disease Control and Prevention (CDC), known pathogens account for an estimated 14 million illnesses, 60,000 hospitalizations, and 1,800 deaths each year i...

Researchers have developed a new method for studying bacterial swimming, one that allows them to trap Escherichia coli bacteria and modify the microbes' environment without hindering the way they move.
The new approach, described this month in Nature Methods, uses optical traps, microfluidic ... Read More

A very important message to women who are pregnant. Listeria monocytogenes is very dangerous for anyone who is immunocompromised and it is one of few bacterial pathogens that can cross the fetal-placenta barrier and infect the fetus, usually resulting in fetal death. The USDA produced this vid... Read More

A pilot program is allowing some Maryland creameries to manufacture and sell raw milk cheese. This video takes you to Chapel County Creamery to see the unpasteurized process first hand. Read More
Researchers from Brown University and McGill University have discovered that the natural killer, or NK cells, help prevent T cells from over-responding when a virus hits. This balance helps prevent T cells, which ordinarily serve the immune system, from causing harm.
Natural killer, or NK cel... Read More
"Michael Storrie-Lombardi, PhD, from Kinohi Institute (Pasadena, CA), and Birgit Sattler, PhD, from the University of Innsbruck, Austria, used laser-induced fluorescence emission (L.I.F.E.) imaging to detect red and infrared fluorescence activity produced by cyanobacteria present in the ice of f...

Before there were dinosaurs and the continents still formed what is known as Pangaea, there was Reduviasporonites. This wood eating fungus dominated our planet's land mass following a global catastrophe that saw Basalt lava flows which exterminated up to 96 per cent of all marine species and 70 ... Read More
Researchers at Kitasato University Graduate School of Medical Sciences in Sagamihara, Kangawa Prefecture were last night awarded an Ig Nobel Prize in biology for displaying that bacterial extracts from panda poop can play a role in composting.
In a series of published papers, the university’s... Read More
Researchers working with dangerous pathogens that could be exploited by terrorists should become “stewards of their science”, according to a report released this week by the US National Research Council (NRC). The report outlines a set of nine recommendations which aim at developing a culture of... Read More

Mercury pollution is a persistent problem in the environment. Human activity has lead to increasingly large accumulations of the toxic chemical, especially in waterways, where fish and shellfish tend to act as sponges for the heavy metal.
It's that persistent and toxic nature that has flummox... Read More
New research may calm fears that the common infection strep throat can lead to certain neuropsychiatric disorders.
While previous research has linked streptococcal infection of the throat to Tourette syndrome and obsessive-compulsive disorder (OCD), a new study out of the United Kingdom finds... Read More
The largest U.S. supplier of seasonal flu vaccines said it is running behind on shipping those vaccines — partly because of the crunch to produce millions of doses of the swine flu vaccine.
The pharmaceutical company Sanofi Pasteur said it has shipped more than half of the 50.5 million doses ... Read More
BIRMINGHAM, Ala. – The optimal way to control swine flu, the new H1N1 virus that emerged as a global threat in 2009, is to vaccinate children with the planned H1N1 flu vaccine, says the co-director of the University of Alabama at Birmingham (UAB) Division of Pediatric Infectious Diseases.
