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

"The premier flu-fighting drug is contaminating rivers downstream of sewage-treatment facilities, researchers in Japan confirm. The source: urinary excretion by people taking oseltamivir phosphate, best known as Tamiflu.
Concerns are now building that birds, which are natural influenza carrie... 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.
"Ch... Read More
Last Christmas, St. Louis mom Linda Churchwell-Varga noticed what looked like four little bug bites on her 3-year-old daughter Oona's bottom. Diaper ointment helped at first, but within a few days, more bumps cropped up. They were so painful, Oona refused to sit in a grocery cart. Recalls Linda:... Read More
Ever awkwardly tried to open a door with your sleeve as a barrier against that dirty doorknob? Or done the tricky dance of attempting to flush the toilet with your foot to avoid that germ-laden handle?
Despite your dances to avoid seemingly obvious germ hang-outs, the dirtiest surface in your... Read More
In recent years, efforts to combat drug-resistant bacteria have focused on the immediate goal of reducing rates of hospital-acquired infections. But now global health officials face an approaching crisis: the number of different antibiotics available to treat such infections when they do occur i... Read More
Bacterial lung infections were common among 77 people who died because of the 2009 H1N1 flu, a finding similar to past pandemics, the CDC said.
In a subset of the 600 U.S. deaths associated with the current pandemic, 29% had a bacterial coinfection, the agency said in a early release from the... Read More
Engineered E. coli bacteria can now trace the outline of an image on an agar plate in a feat that shows how manipulating small organisms could lead to synthetic biological devices useful to technology and medicine.
"It looks like a pen came in and traced the outline of the image," said Jeff T... Read More
Scientists are reporting discovery of a much sought after crack in the armor of a common microbe that infects the stomachs of one-sixth of the world’s population, causing stomach ulcers and other diseases. They identified a group of substances that block a key chemical pathway that the bacteria ... Read More
