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

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
The spread of lethal diseases from animals to humans has long been an
issue of great concern to public health officials. But what about
diseases that spread in the other direction, from humans to wildlife?
A multidisciplinary team of researchers at the University of Georgia
(UGA) has jus... Read More
Novartis AG (NVS) Monday said it will submit meningococcal disease vaccine Menveo in the U.S. and elsewhere to treat children aged two months and older after fresh late-stage trials showed the drug to be effective to treat infants.
Menveo, which already passed the regulatory hurdle in the U.S... Read More
Cholera, a virulent illness that comes on quick and can be fatal mere hours after symptoms appear, kills more than 100,000 people a year.
The infection is characterized by chronic diarrhea, rapidly leading to life-threatening dehydration and electrolyte imbalances. And because nearly three-qu... Read More
The same taste buds we have on the tongue to detect bitterness also exist on lung muscle so that the airways can "taste" dangerous illness-causing bacteria, according to new research published Sunday that could lead to better treatments for respiratory conditions.
When the taste receptors in ... Read More

The H1N1 swine flu virus might be mutating. A new form of the virus has started to predominate in Australia, New Zealand and Singapore according to a new report in Eurosurveillance.
The World Health Organization (WHO) says more study will tell whether the new strain is deadly and whether the ... Read More
