Chlorine, a disinfectant commonly used in most wastewater treatment plants, may be failing to completely eliminate pharmaceuticals from wastes. As a result, trace levels of these substances get discharged from the plants to the nation's waterways. And now, scientists are reporting preliminary st... Read More
For people infected with the human papilloma virus (HPV), the likelihood of clearing the infection and avoiding HPV-related cancer may depend less on the body's disease-fighting arsenal than has been generally assumed. Read More
Although natural selection is often thought of as a force that determines the adaptation of replicating organisms to their environment, Harvard researchers have found that selection also occurs at the level of neurons, which are post-mitotic cells, and plays a critical role in the emergence of A...

Potentially toxic microbes which pose a threat to our drinking water have undergone a dramatic population explosion over the last 200 years as a result of pollution, research involving experts from The University of Nottingham has found. The study, published in the journal Ecology Letters, looke... Read More
Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome, new research shows.

The first of a group of 10 American aid workers who may have come into contact with the Ebola virus in Sierra Leone were evacuated on Saturday, American government and aid officials said. They will be the largest group of Americans to have returned home over fears of exposure to the virus since ... Read More
Leprosy is a chronic infection of the skin, peripheral nerves, eyes and mucosa of the upper respiratory tract, affecting over a quarter million people worldwide. Its symptoms can be gruesome and devastating, as the bacteria reduce sensitivity in the body, resulting in skin lesions, nerve damage ... Read More
In one of the most comprehensive analyses of immune function performed to date, researchers analyzed blood samples from 105 sets of healthy twins. They measured immune cell populations and their chemical messengers—204 parameters in all—before and after participants received a flu shot. Differen... Read More
Because viruses must bind to cell surface molecules to initiate replication, the use of soluble receptors to block virus infection has long been an attractive therapeutic option. Soluble receptors have been developed that block infection with rhinoviruses and HIV-1, but these have not been licen... Read More
A new paper-based platform has been created for conducting a wide range of complex medical diagnostics. The key development was the invention of fluid actuated valves embedded in the paper that allow for sequential manipulation of sample fluids and multiple reagents in a controlled manner to per...

Significant accumulations of polyphosphate granules have been found in three common sponge species of the Caribbean coral reef, indicating that microorganisms that live on marine sponges are pulling phosphorus out of the water to feed themselves and survive in a deep-water environment where very...

We, as most animals, host many different beneficial bacteria. Being beneficial to the host often pays off for the bacteria, as success of the host determines the survival and spread of the microbe. But if bacteria grow too much they may become deadly. In a new study published in the latest editi... Read More
Saudi Arabia has not done enough to investigate and control a deadly new MERS virus that has killed hundreds of people there and remains in many ways a mystery, United Nations health experts said on Monday.
Cases of Middle East Respiratory Syndrome (MERS) are surging again, but Saudi health o... Read More
President Ellen Johnson Sirleaf of Liberia on Friday urged the United States to maintain its assistance to her country as it continues to fight to recover from the Ebola outbreak, which began about one year ago.
In a meeting at the White House with President Obama, Ms. Johnson Sirleaf asked f... Read More
An otherwise balanced review of selected aspects of Ebolavirus transmission falls apart when the authors hypothesize that ‘Ebola viruses have the potential to be respiratory pathogens with primary respiratory spread.’
The idea that Ebolavirus might become transmitted by the respiratory route ... Read More
A potentially life-threatening gastrointestinal infection is more common than previously estimated, federal health officials reported Wednesday.
The infection, caused by a bacterium known as Clostridium difficile, or C-diff, causes nearly 500,000 illnesses in the United States each year and k... Read More
When calves are infected by two parasite species at the same time, one parasite renders the other far less deadly, according to a new study published in the current journal of Science Advances Read More
U.S. authorities are considering imposing tougher restrictions in Arkansas to contain a virulent strain of avian flu in the heart of America's poultry region in a bid to minimize international trade disruptions and contain the virus.
The H5N2 flu discovered in Arkansas last week is the state'... Read More
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The existence of ultra-small bacteria has been debated for two decades, but there hasn't been a comprehensive electron microscopy and DNA-based descriptio... Read More
A team of scientists including Virginia Tech researchers is one step closer to understanding how bacteria on a frog's skin affects its likelihood of contracting disease. Read More
