n findings they call counterintuitive, a team of UCLA-led researchers suggests that blocking a protein, which is crucial to initiating the immune response against viral infections, may actually help combat HIV.
Findings from a study in animals appear to demonstrate that temporarily blocking a... Read More
In a study that could have significant impact on how disease outbreaks are managed, researchers at UC Davis and the California Department of Public Health (CDPH) have sequenced and analyzed genomes from Shigella sonnei (S. sonnei) bacteria associated with major shigellosis outbreaks in Californi...

The TWiVnauts present another example of an infectious but replication incompetent vaccine, an insect specific arborvirus bearing chikungunya virus structural proteins.
Perhaps with more enthusiasm than originality, I feel compelled at the end of the year to look back on what has happened in my life. The compulsion is even stronger this December, since the end of the calendar year coincides with my first year at the helm of ASM as its CEO.
When I joined AS... Read More
Investigators at Johns Hopkins report they have new evidence that a bacterium known to cause chronic inflammatory gum infections also triggers the inflammatory “autoimmune” response characteristic of chronic, joint-destroying rheumatoid arthritis (RA). The new findings have important implication... Read More
Investigators from the Ragon Institute of MGH, MIT and Harvard and the Broad Institute of MIT and Harvard have used the revolutionary new gene-editing technology CRISPR-Cas9 to identify three promising new targets for treatment of HIV infection. In their report receiving advance online publicati... Read More
Crafting a vaccine against RSV (respiratory syncytial virus) has been a minefield for 50 years, but scientists believe they have found the right balance.
Researchers at Emory University School of Medicine and Children's Healthcare of Atlanta report that they have engineered a version of RSV t... Read More
The video shows the structural changes in the Caulobacter crescent VapBC1 protein complex during DNA binding, including how the antitoxin “tails” containing the protein palindromic sequences switch positions.

Antibiotic resistance in pathogenic bacteria is a growing global challenge. Danish researchers have now discovered that bacteria use a code language to avoid being controlled. Understanding this code language will be paramount to developing new antibiotics in the future.
Pathogenic bacteria –... Read More
Chemist Pieter Dorrestein’s laboratory group has been developing mass spectrometry methods to look at what molecules are produced by microbes interacting in a petri dish. But recently, the group jumped out of the dish and into the dirt—to analyze a soil-dwelling lichen and discover how the molec... Read More
Researchers from The University of Texas Medical Branch at Galveston have developed the first vaccine for chikungunya fever made from an insect-specific virus that doesn’t have any effect on people, making the vaccine safe and effective. The newly developed vaccine quickly produces a strong immu... Read More
Researchers from The University of Texas Medical Branch at Galveston have developed a vaccine against salmonella poisoning designed to be taken by mouth. The findings are detailed in an article published in Frontiers in Cellular and Infection Microbiology.
In earlier studies, the UTMB researc... Read More
Scientists at the University of Liverpool have shown that a change in weather patterns, brought on by the 'Godzilla' El Niño of 2015, fuelled the Zika outbreak in South America.
The findings were revealed using a new epidemiological model that looked at how climate affects the spread of Zika ... Read More
A centuries-old herbal medicine, discovered by Chinese scientists and used to effectively treat malaria, has been found to potentially aid in the treatment of tuberculosis and may slow the evolution of drug resistance.
In a promising study led by Robert Abramovitch, a Michigan State Universit... Read More
Sunlight allows us to make vitamin D, credited with healthier living, but a surprise research finding could reveal another powerful benefit of getting some sun.
Georgetown University Medical Center researchers have found that sunlight, through a mechanism separate than vitamin D production, e... Read More
In recent years, researchers have learned that gut microbiota play a role in a number of human diseases, including Clostridium difficile infection, irritable bowel syndrome, Parkinson’s disease, and autism spectrum disorder. The revelations have scientists hopeful that fecal microbiota transplan... Read More
New UCLA-led research finds that Zika-linked abnormalities that occur in human fetuses are more extensive — and severe — than previously thought, with 46 percent of 125 pregnancies among Zika-infected women resulting in birth defects in newborns or ending in fetal death.
The study, published ... Read More
Scientists have discovered the mechanism that hijacks the immune system's response to tuberculosis, revealing an important new drug target for the disease that kills more than 1 million people each year.
Herman Sintim, Purdue University's Drug Discovery Professor of Chemistry, collaborated wi... Read More
European experts have noted an increasing trend of listeriosis since 2008, but they highlight that the number of affected people stabilised from 2014 to 2015. Infections were mostly reported in people over 64 years of age. These are some of the findings of the latest annual report by EFSA and EC... Read More
Fungal infections are a serious health risk. They can be harmful especially to patients whose immune system is compromised through illness or chemotherapy. A team working at the Technical University of Munich (TUM) has discovered an important mechanism in the body's defenses against fungi. The d... Read More
