MOSQUITOES infected with bacteria that stop them transmitting the dengue virus will be released into the wild next year.
Some 100 million people in the tropics get dengue fever each year, and 40,000 are killed by it. The virus's range is expanding, and last week France reported its first loca... Read More
A team of Yale University scientists has engineered the cell wall of the Staphylococcus aureus bacteria, tricking it into incorporating foreign small molecules and embedding them within the cell wall.
The finding, described online in the journal ACS Chemical Biology this week, represents the ... Read More
Almost all U.S. doctors in a survey released on Thursday said they plan to get vaccinated against flu this season, a finding that heartened disease experts frustrated by low vaccination rates.
"Now we need to get other health care professionals to move in this same direction," said Dr. Willia... Read More
Alan Boyle writes: Bacteria have legs? That suggestion seemed surprising to Gerard Wong, a bioengineering professor at the University of California at Los Angeles, when his students told him they were seeing some strange behavior in movies of the microbes.
"They said, 'You know, we noticed th... Read More
The bacterium Campylobacter jejuni is a major cause of food poisoning in humans. It is normally transmitted from contaminated chicken meat, as it is frequently found in the intestines of chickens, where it apparently does not result in any symptoms. Campylobacter jejuni is well adapted to life ... Read More
NIH Intramural Researcher Dr. Julie Segre talks about the Human Microbiome Project in an interview produced by the NIH Common Fund. Read More
The ups and downs of the bacteria in an oil field provide a useful source of information for keeping tabs on the state of the oil field itself. In theory, this process known as 'biomonitoring' can increase the yield from an oil field. This is the conclusion reached by Geert van der Kraan, who ob... Read More

Doctors have long known that viral infections can bring about asthma attacks and the shortness of breath, coughing, and wheezing associated with them. But while viral infections cannot be treated, scientists at the Danish Paediatric Asthma Centre (DPAC) at the University of Copenhagen and Gentof... Read More
It has been one of the great murder mysteries of the garden: what is killing off the honeybees?
Since 2006, 20 to 40 percent of the bee colonies in the United States alone have suffered “colony collapse.” Suspected culprits ranged from pesticides to genetically modified food.
Now, a uniqu... Read More
Bacteria around open-net pen salmon farms are developing a resistance to antibiotics, a two-year study in the Broughton Archipelago has found.
"They are not actually resistant, but if we do these special tests, we can see the [tolerance for antibiotics] is higher than you would expect it to b... Read More
A new study links flare-ups of cystic fibrosis to a chronic bacterial infection, a finding that could give physicians new insight into the disease and offer a new target for medication.
The germ in question is called Stenotrophomonas maltophilia.
"Our study showed that chronic infection wi... Read More
The stuff doesn’t even smell that bad.
In Henhouse No. 1 at the Hi-Grade Egg Farm here, the droppings from 381,000 chickens are carried off along a zig-zagging system of stacked conveyor belts with powerful fans blowing across them.
The excrement takes three days to travel more than a mil... Read More
Researchers since the 1950s have studied dangerous animal diseases here that if unleashed could imperil the nation's livestock. Cold War germ warfare testing also occurred on Plum Island, and for decades the U.S. Army used it as a coastal defense post.
Nevertheless, many environmentalists cha... Read More
For the first time, a treatment in mice has shown promise against the final, metastatic stages of terminal cancer. Unusually, the antibody targets healthy tissue, not tumour cells, suggesting normal cells play an unwitting role in terminal cancers.
The mouse treatment uses an antibody that bi... Read More
The pursuit of renewable sources of energy just hit a crucial breakthrough. Since the stores of fossil fuel are diminishing as we speak, researchers are trying to exploit the machinery of microorganisms for the production of diverse chemical compounds, which can be consumed by themselves or late...

A strain of a drug-resistant skin disease that has afflicted sports teams, prisons and military units is now proving a persistent pest among lobstermen and their families on a Maine island.
Over the past two summers, more than 30 people on Vinalhaven have come down with painful and persistent... Read More
Worldwide screening should begin "immediately" for New Delhi metallo-beta-lactamase-1, or NDM-1, an enzyme that renders bacteria resistant to a broad range of beta-lactam antibiotics.
On Sept. 15, France began screening all patients admitted to French hospitals who had been hospitalized abroa... Read More
A chemical compound made from a type of bacteria discovered in the Florida Keys appears to be effective in fighting colon cancer in preclinical experiments.
The compound—known as largazole because it was first found near Key Largo—inhibits human cancer cell growth in cultures and rodent model... Read More
