Deep under the Mediterranean Sea, small animals have been discovered that live their entire lives without oxygen and surrounded by 'poisonous' sulphides. Researchers writing in the open access journal BMC Biology report the existence of multicellular organisms (new members of the group Loricifer... Read More
Four drugs that are used to treat the AIDS virus HIV can also inhibit the replication of xenotropic murine leukemia virus-related virus (XMRV), a mouse virus that has been found in some patients with prostate tumors and chronic fatigue syndrome. Now all researchers have to do is show that XMVR i... Read More
The traditional seasonal flu vaccine may have increased the risk of infection with pandemic H1N1 swine flu, according to the results of four new studies by Canadian researchers.
In one study, the researchers used an ongoing sentinel monitoring system to assess the frequency of prior vaccinati... Read More
Jonathan Eisen (@phylogenomics on Twitter) has a new post on his The Tree of Life blog that looks at why the paper "Phylogenetic structure of the prokaryotic domain: The primary kingdoms" by Carl Woese and George Fox may be the most important paper (see http://www.pnas.org/content/74/11/5088.ful...

An infectious virus linked to two diseases is drawing the attention of public-health officials, who are investigating the potential threat to the nation's blood supply.
It isn't clear if the virus, known as XMRV, poses a danger, and public-health officials say there isn't evidence of spreadin... Read More
Merry Youle of Small Things Considered fame has a new post on the site that looks at the Acidianus two-tailed virus.
"Why two tails? Why such long tails? The researchers note that ATV is the only virus of an acidophilic hyperthermophile known to lyse its host, albeit only under st... Read More
Detecting one of the world's most common pathogens in drinking water soon may no longer be bottle-necked under a laboratory microscope.
Pathogens, meet technology. A new system developed by Texas AgriLife Research automatically scans a water sample and points to potential pathogens much faste... Read More
How would this affect hypochondriacs I wonder? Probably degrade their mental state whilst simultaneously boosting their immune response. Maybe videos of sick people should be shown in hospitals too, unless there is a point where the positive effect drops off. Either way, interesting stuff. ... Read More
Fascinating piece, something I had never really considered before - the idea that bacteria can get sick, similar to the idea can soap get dirty eh? Hopefully the anti-vaccine crowd won't get all up in arms about this, they've done enough damage in the human population already. Also begs the qu... Read More
A new fast-acting disinfectant that is effective against bacteria, viruses and other germs could help stop the spread of deadly infections in hospitals, German scientists said on Wednesday.
Researchers from the Robert Koch Institute in Berlin said they had developed a fast-acting, practical f... Read More
The mysterious life cycle of a sheep virus that causes malignant catarrhal fever (MCF) has been discovered by Agricultural Research Service (ARS) scientists and their university collaborators -- the first step in developing a vaccine against the disease.
Microbiologist Hong Li and veterinary ... Read More
Highly dangerous Cryptococcus fungi love sugar and will consume it anywhere because it helps them reproduce. In particular, they thrive on a sugar called inositol which is abundant in the human brain and spinal cord.
To borrow inositol from a person's brain, the fungi have an expanded set of ... Read More
Tim Sampson, a graduate student at Emory University in the Microbiology and Molecular Genetics program, looks at two research papers with conflicting conclusions about the presence of endospores in very late stationary phase cultures of Mycobacterium marinum, a common model for acute Mycobacte...

Cornell researchers have created mathematical models based on interactions between species in coral reef communities that may provide insight as to why certain bacteria may help cause the reef to become bleached and ultimately destroyed.
The models and their implications for the overall healt... Read More
A description of a 95-million-year-old amber deposit—the first major discovery of its kind from the African continent—is adding new fungus, insects, spiders, nematodes, and even bacteria to an ecosystem that had been shared by dinosaurs. In addition, the amber deposit may provide fresh insights ... Read More
Norovirus has been in the news of late for sickening passengers on cruise ships, closing a middle school and postponing a college swim meet.
The virus, which causes severe gastrointestinal symptoms, has also been in my house. I most likely contracted the virus last week and have been shocked ... Read More

Scientists from the California Institute of Technology (Caltech) have provided the first-ever glimpse of the structure of a key protein -- gp120 -- found on the surface of a specific subgroup of the human immunodeficiency virus, HIV-1. In addition, they demonstrated that a particular antibody to... Read More
