Toxoplasma gondii is estimated to chronically infect nearly one-third of the world's population, causing the condition Toxoplasmosis. It is most commonly associated with handling cat feaces and is a particular threat to pregnant women and immune-compromised individuals, such as HIV/AIDS patients... Read More
For thousands of years, people have used yeast to ferment wine, brew beer and leaven bread. Now researchers at Stanford have genetically engineered yeast to make painkilling medicines, a breakthrough that heralds a faster and potentially less expensive way to produce many different types of pla...

BOC Sciences-Studies have found that peptides produced by a certain type of gut bacteria can be used to prevent type 1 diabetes from deteriorating and the lack of such gut bacteria along with the peptides may be the reason for type 1 diabetes in newborn babies.
The study was conducted by a co... Read More
Since the chickenpox vaccine became available in the U.S. in 1995, there has been a large reduction in chickenpox cases. Hospitalizations and outpatient visits for chickenpox have continued their decline after a second dose of the vaccine was recommended to improve protection against the disease... Read More
Vaccinating one-year-olds against chickenpox could temporarily nearly double the incidence of shingles in the wider population, but in younger adults than previously thought. Read More
In midsummer 1986, five years after starting my poliovirus laboratory at Columbia University, I received a letter from Frederick L. Schaffer, a virologist at the University of California, Berkeley, asking if I would like to have his collection of poliovirus stocks. He was retiring and the sample... Read More
New research on monkeys vaccinated against HIV's relative SIV calls into question an idea that has driven AIDS vaccine work for years. The assumption: a protective vaccine only needs to stimulate moderate levels of antibodies that neutralize the virus. Read More
HIV can continue to grow in patients who are thought to be responding well to treatment, according to research by the University of Liverpool. Read More
An Ebolavirus vaccine has shown promising results in a clinical trial in Guinea. This vaccine has been in development since 2004 and was made possible by advances in basic virology of the past 40 years. Read More
BOC Sciences-There is a new species of bacteria found by scientists from The Scripps Research Institute (TSRI) for a kind of enzyme it produces that can be used as an interfering substance to achieve smoking cessation. This finding will be smokingof considerable significance for its effectivenes... Read More
Current smoking cessation aids fail in 80 to 90 percent of smokers. The idea behind this therapy would be to destroy nicotine before it reaches the brain—depriving a person of the “reward” of nicotine that can trigger relapse into smoking. Pseudomonas putida, a bacterium typically found in tobac... Read More
COLUMBUS, Ohio - Researchers who have revealed a highly efficient way that bacteria use toxins to interrupt the immune response say that until now, the trickery of these toxins has been underappreciated in science. Read More
The compound that detectives spray at crime scenes to find trace amounts of blood may be used one day to kill the malaria parasite. Read More
BOC Sciences-Anti-aging has long been a research and study subject, but few breakthrough has been made since no original reason was found for this normal body change with age increasing. Recently scientists from TSRI may find the underlying reason for aging diseases. Read More
Johns Hopkins Bloomberg School of Public Health researchers say they have developed a method that could make a nasal spray flu vaccine effective for those under two and over 49 - two groups for which the vaccine is not approved. Read More
National Institutes of Health (NIH) scientists report that a single dose of an experimental Ebola virus (EBOV) vaccine completely protects cynomolgus macaques against the current EBOV outbreak strain, EBOV-Makona, when given at least seven days before exposure, and partially protects them if giv...
