Scientists with the U.S. Department of Agriculture (USDA) are helping ensure that the smoked salmon that's always a hit at festive gatherings also is always safe to eat, including among their achievements the development of a first-of-its-kind mathematical model that food processors and others c...

Eighteen people have died in the Brazilian capital after contracting a hospital superbug.
They were infected with bacteria which produce the enzyme Klebsiella pneumoniae Carbapenemase (KPC), which renders most modern antibiotics ineffective.
It tends to infect hospitalised people whose imm... Read More
Cytomegalovirus (CMV) infection in kidney or kidney/pancreas transplant recipients occurs more frequently when alemtuzumab is used for induction instead of antithymocyte globulin (ATG), according to a new study from the University of Minnesota in Minneapolis.
In addition, in alemtuzumab recip... Read More
The World Health Organization on Tuesday announced a mass polio vaccination campaign in Africa, the same day Ugandan health officials announced an outbreak of the highly infectious disease.
WHO officials in Geneva said the 15-country campaign would start as early as next week in Angola and Co... Read More
While the cholera outbreak that has so far killed 259 in Haiti is starting to taper off, the capital Port-au-Prince is bracing itself for the disease's arrival. Can treatment reach people in time to prevent more deaths?
Emergency supplies of clean water, soap and water-purifying equipment con... Read More
When it comes to biology, the proteins get all the glory. A new study coming out in mBio might change this, though: the results show that, in the immune response, non-protein-coding RNAs may deserve some credit for what they do, too.
Peng et al. used whole transcriptome analysis in mice to e... Read More
Press release from National Institute of Allergy and Infectious Diseases (NIAID) on the significance a Genome Announcement by Steven E. Schutzer, Claire M. Fraser-Liggett, Sherwood R. Casjens, Wei-Gang Qiu, John J. Dunn, Emmanuel F. Mongodin, and Benjamin J. Luft published ahead of print in the... Read More
For the first time, scientists have discovered that a poorly understood class of RNA produced in a mammal's cells during a respiratory virus attack may affect the outcome of the infection. Their findings are reported today in mBio, a journal of the American Society for Microbiology.
RNA (ribo... Read More
New strategies to apply antibiotics more effectively to hibernating bugs have been developed by researchers at the University of Hertfordshire.
In a paper, which appeared this month in the Institute of Electrical and Electronics Engineers (IEEE) Transactions on Evolutionary Computing, Dr Ole ... Read More
Listeria bacteria, a source of food-borne illness, tricks cells in the body's intestines to pass through those cells and make people sick, researchers say.
Researchers at Purdue University found that listeria, even in low doses, somehow triggers intestinal cells to express a protein that acts... Read More
China's health authorities Tuesday announced the country's first three cases of NDM-1, a multi-drug resistant super bacteria.
Chinese Center for Disease Control and Prevention (China CDC) official Ni Daxin said at a press conference that two cases were detected from samples submitted by the l... Read More
A newly developed sensor may revolutionize how drugs and medical devices are tested for contamination.
In the process it may also help ensure the survival of two species of threatened animals. To be fair, some of the credit goes to an African frog.
In the wild, the African clawed frog pro... Read More
Vincent and Dickson discuss the intracellular parasite Cryptosporidium, which causes diarrheal disease in most mammalian species.

In episode #1 of Twip Dr. Despommier mentioned the gap between protozoans and nematodes with respect parasitism. I wonder if this claim takes into account the fish parasite Buddenbrockia plumatellae. Because its body is vermiform... Read More
The rate of deaths in Haiti's cholera epidemic slowed on Monday, officials said, as a multinational medical operation ramped up to curb an outbreak that has killed 259 people in the earthquake-hit country.
After several days in which fatalities had numbered dozens each day, only six deaths we... Read More
A new study casts further doubt on the role of a retrovirus, XMRV, in human disease, adding weight to the possibility that earlier studies finding a link between the virus and cancer and chronic fatigue syndrome may have been wrong.
In the study, researchers from the National Cancer Institute... Read More
A giant virus that infests microscopic sea creatures has the largest genome of any marine virus, and the second largest of any virus. Its genome includes a host of genes not normally found in viruses, lending support to claims that viruses had a critical role in the evolution of complex life.

A fluorescent image of the heart of a mosquito taken by a Vanderbilt graduate student has captured first place in Nikon’s “Small World” 2010 photomicrography competition.
Jonas King took the image that shows a section of the tube-like mosquito heart magnified 100 times. He is a member of the ... Read More
When most genes are transcribed, the nascent RNAs they produce are not quite ready to be translated into proteins - they have to be processed first. One of those processes is called splicing, a mechanism by which non-coding gene sequences are removed and the remaining protein-coding sequences ar... Read More
Scientists have uncovered a novel mechanism by which Salmonella bacteria infect humans and say the discovery could potentially be exploited to kill cancerous cells.
In an article published in the journal Science, researchers from the University of Glasgow and the University of Massachusetts M... Read More
