Carl Zimmer at Discover Blogs has an interesting follow up on two studies he wrote about in March that suggested there may be some evidence in newly found viruses for a fourth branch on the tree of life. In this piece he highlights a new study by Tom Williams, Martin Embley, and Eva Heinz of the... Read More
I did the homework Professor Vince assigned and went to see the movie Contagion. I really liked the movie and was very pleased with the way the science was portrayed.
I am an Environmental Health and Safety Manager ... Read More
If you know anything about snakes you might be familiar with snake inclusion body disease, or IBD. This transmissible and fatal disease affects snakes of a variety of species but has been best studied in boas. The name comes from the presence of large masses (inclusions) in the cytoplasm of cell... Read More
New research shows that killer whales are inhaling bacteria, fungi and viruses once believed to be found only on land. Some of the pathogens are highly virulent. And some are even antibiotic-resistant.
The scientists followed the killer whales by boat, trying to catch the precise moment the a... Read More
Scientists are reporting development and successful testing of a rapid and accurate test to tell the difference between bacterial and viral infections. Those common afflictions often have similar symptoms but vastly different treatments - antibiotics work for bacterial infections but not for vir... Read More
Two controversial papers on bird flu will be published by scientific journals this year after the go-ahead was given by a U.S biosecurity panel.
The National Science Advisory Board for Biosecurity (NSABB) took a stand over the papers last year out of concerns that details of the studies - whi... Read More
If you make your own yogurt, there's a chance your yogurt could outlive you.
That's because some bacteria that grow and feed on the sugar in milk – the process that ferments milk into yogurt — can procreate indefinitely in new generations of yogurt.
But not all yogurts have these immortal po... Read More
Soil samples obtained from South American volcanoes have revealed a smattering of different microbe types that have somehow managed to survive in extreme conditions, the University of Colorado-Boulder (CU-Boulder) announced in a June 8 press release.
According to the university, the scientist... Read More
The bacteria in your mouth could one day be used as an early test for pancreatic cancer, a new study suggests.
In a small study, pancreatic cancer patients were found to have different levels of certain bacteria in their saliva than healthy people did. While researchers weren't sure if the ... Read More
A drug candidate that has shown promise for neutralizing dangerous bacteria also prevents growth of the parasite that causes malaria, new research by a Yale University team headed by Nobel laureate Sidney Altman shows.
The compound created in the labs of Altman and co-senior author Choukri Be... Read More
In 1969 David Baltimore proposed that poliovirus RNA replication is coupled with packaging, in that only those genomes actively replicating will be selectively encapsidated. From an evolutionary standpoint, it is an ingenious requirement to ensure that only virus genomes capable of replication ... Read More
A synthetic mixture of intestinal bacteria could one day replace stool transplants as a treatment for Clostridium difficile (C. difficile). C . difficile is a toxin-producing bacteria that can overpopulate the colon when antibiotics eradicate other, naturally protective bacteria living there.

Sing it with us: What lives in the rainforest, under a tree? Spongiforma squarepantsii, a new species of mushroom almost as strange as its cartoon namesake.
Its discovery in the forests of Borneo, says San Francisco State University researcher Dennis Desjardin, suggests that even some of the ... Read More
As a pediatrician, I spend a lot of time looking for bacteria that might be making my patients sick. Some well-known illnesses that are caused by bacteria include strep throat, ear infections, Lyme disease and conjunctivitis (pinkeye). Bacteria are also responsible for acne, cavities and body od...

A bacteria that is known to be associated with more than 80% of gastric and doudenal ulcers, may be associated with infant colic. The bacteria, Helicobacter Pylori (H.pylori), is found in the lining of the of the stomach wall.
Dr. Abdelrazak Mansour Ali from Al-Azhar University in Cairo, Egyp... Read More
MIT and Harvard researchers have developed technologies that could be used to rewrite the genetic code of a living cell, allowing them to make large-scale edits to the cell’s genome. Such technology could enable scientists to design cells that build proteins not found in nature, or engineer bact... Read More
A new electron microscope that works without a lens may create the highest resolution images ever seen.
Transmission electron microscopy (TEM), which looks through an object to see atomic features within it, has been constrained for over 70 years by the relatively poor lenses that are used to... Read More
The discovery of microbes in any icy lava tube in Oregon raises hope that similar microorganisms could survive in the very similar conditions to be found on Mars.
The microbes are coping with near-freezing temperatures and low levels of oxygen, and can even grow in the absence of organic food... Read More
The Obama administration has announced a new policy to handle the risks posed by legitimate biological research that could, in the wrong hands, threaten the public.
The move comes in response to a huge debate over recent experiments on bird flu virus that got funding from the National Institu... Read More
