The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical Atlantic ocean. This runoff forms a freshwater plume, hundreds of miles across, that profoundly affe... Read More
Alberta health officials have confirmed an isolated, fatal case of H5N1 or avian influenza, federal Health Minister Rona Ambrose said Wednesday.
But officials repeatedly emphasized that there is no risk of transmission between humans.
The infected person, an Alberta resident who recently ... Read More
Purdue University researchers successfully eliminated the native infection preferences of a Sindbis virus engineered to target and kill cancer cells, a milestone in the manipulation of this promising viral vector.

Love may be a battlefield, but most wouldn't expect the fighters to be a parasitic virus and its cricket host. Just like a common cold changes our behavior, sick crickets typically lose interest in everyday activities. But when Dr. Shelley Adamo of Dalhousie University found her cricket colony d... Read More
What if something as simple as the common cold could help treat one of the deadliest forms of cancer?
That’s exactly what researchers at The Ohio State University Comprehensive Cancer Center are trying to find out through a clinical trial testing viral therapy on pancreatic cancer. The diseas... Read More
CHICAGO, Jan. 6 (UPI) -- The largest outbreak ever of a rare but potentially deadly bacteria has been tied to equipment in a Chicago-area hospital, health officials said.
The Centers for Disease Control and Prevention said 44 cases of infection by the bacteria carbapenem-resistant enterobacteri... Read More
Mexico is considered one of the leading countries in papaya productions, but its crops are usually affected by the virus of the ringed spot, which leaves ring marks in the skin of the fruit and causes softening of the papaya, where fungi start to digest it. This is why the Center of Research and... Read More
Family gatherings helped spread influenza during the 2013 holiday season, as the pace of flu reports jumped at year end, according to the U.S. Centers for Disease Control and Prevention.
About 4.3 percent of doctor visits during the week ended Dec. 28 were for complaints of flu-like symptoms ... Read More
An Auckland scientist has invented molecules that can attach themselves to any surface in a few minutes and modify every type of cell or virus. The potential for the technology is huge - from attacking cancer cells to protecting newborn babies. Read More
This episode: Cold-loving bacteria can repair surprising amounts of DNA damage even sub-zero temperatures!
(9.1 MB, 9.9 minutes)
Bacteria isolated from the Siberian arctic permafrost are exposed to a lot of radiation over thousands of years, but somehow they are able to repair... Read More
To know how many proteins assemble together at the nanoscale is fundamental for understanding protein function. Sometimes, proteins must be in an "oligomeric" state to be functional, although "oligomerization" of certain proteins can also lead to diseases. The ability to determine protein stoich... Read More
Mating and meiosis – the specialized cell division that reduces the number of chromosomes in a cell – are related, but in most yeasts they are regulated separately. Not so in Candida lusitaniae, where the two programs work in unison, according to a new study in Nature. Comparison with other spec... Read More
We're pleased to reprint here in slightly shorted form a recent post from Lucas’ Thoughtomics, a Scientific American blog whose aim is “Exploring evolution through genes, computers and history." By kind permission.
Microbiologists have long noted something odd about the Halobacteria (and not ... Read More
Each year, 2 million people get an infection that is resistant to antibiotics, the CDC has reported. Twenty-three thousand of them die as a result of the infection, and many more die from related complications.
Carbapenem-resistant Enterobacteriaceae (CRE) are just one variety of antibiotic-r... Read More
NASA’s Antibiotic Effectiveness in Space (AES-1) investigation is launching in January and it will be offering scientists more insight into how bacteria behave in microgravity.
Bacteria are considered the most successful life forms, and they are hard to run from, even in space. In a micrograv... Read More
A nanoparticle wrapped in material taken from the membranes of red blood cells could become the basis for vaccines against a range of infectious bacteria, including MRSA (methicillin-resistant Staphylococcus aureus), an infection that kills tens of thousands of people every year.

DNA carries out its activities "diluted" in the cell nucleus. In this state it synthesises proteins and, even though it looks like a messy tangle of thread, in actual fact its structure is governed by precise rules that are important for it to carry out its functions. Biologists have studied DNA... Read More
The lack of data on the effectiveness of medicines available to doctors and researchers is "of extreme concern" say a group of MPs.
The Public Accounts Committee is calling for all data on drugs being prescribed in the UK to be made available.
It also says the government spent £424m stockp... Read More
Membrane proteins are the “gatekeepers” that allow information and molecules to pass into and out of a cell. Until recently, the microscopic study of these complex proteins has been restricted due to limitations of “force microscopes” that are available to researchers and the one-dimensional res... Read More
