Diet Plays a Bigger Role in Shaping Intestinal Microbiota Composition Than Defensins

Researchers at Umeå University, Sweden, have found that among the many factors that shape the intestinal microbiota composition, diet has a much stronger impact than defensins, which are intestinal defence molecules produced by the body.

Researchers Publish a Comprehensive Study of Global COVID-19 Variant Transitions

A team of researchers at Los Alamos National Laboratory recently published the most comprehensive study of global COVID-19 variant transitions, which showed significant diversity in variant spread around the globe related to vaccination rates, number of co-circulating variants and immunity from previous infection.

How Bacteria Take Action to Break Out of Dormancy

Solving a riddle that has confounded biologists since bacterial spores -; inert, sleeping bacteria -; were first described more than 150 years ago, researchers at Harvard Medical School have discovered a new kind of cellular sensor that allows spores to detect the presence of nutrients in their environment and quickly spring back to life.

Occludin Protein Plays a Critical Role in Cell-to-Cell Transmission of SARS-CoV-2 Virus

While the coronavirus continues to infect people around the world, researchers at the University of Missouri have identified a specific protein inside the human body that plays a critical role in how the virus spreads from cell to cell after infection -; a discovery that will help better understand the COVID-19 disease and could lead to the development of new antiviral drugs in the future.

The Pivotal Role of Combinatorial CRISPR Gene Editing in the Elimination of HIV-1 Infection

Recent research from Temple University’s Lewis Katz School of Medicine and the University of Nebraska Medical Center demonstrates that gene-editing therapy aimed at two targets - HIV-1, the virus that causes AIDS, and CCR5, the co-receptor that aids the virus getting into cells—can effectively eliminate HIV infection.

Study Shows Profound Fluctuations in Gut Microbiome Throughout the Day and Across Seasons

The balance of microbes in the human gut varies substantially from morning to night and even more by season -; with profound fluctuations completely transforming the microbiome from summer to winter, according to a study to be presented at Digestive Disease Week 2023.

Cross-Resistant Bacteria from Agricultural Animal as First Line of Defense in Human

New research headed by the University of Oxford has revealed that overuse of antimicrobials in livestock production can lead to the evolution of bacteria more resistant to the first line of the human immune response. The findings were published today in eLife. They show that farmed chickens and pigs could possess huge reservoirs of cross-resistant bacteria, which are capable of powering future epidemics.

Antibacterial Biologic Agent Effective Against Staphylococcus Aureus Infections in Early Tests

Researchers at NYU Grossman School of Medicine and Janssen Biotech, Inc. have shown in early tests that a bioengineered drug candidate can counter infection with Staphylococcus aureus – a bacterial species widely resistant to antibiotics and a major cause of death in hospitalized patients.

Metabolic Network Compatibility Not Likely the Limiting Factor in Prokaryotic Endosymbiosis

"One of the great mysteries of biology," says Eric Libby, former SFI Postdoctoral Fellow, now an associate professor at the Integrated Science Lab (IceLab), Umeå University in Sweden, "is eukaryogenesis, or how eukaryotes arose." Scientists consider this to be a period of major evolutionary transition, critical to our understanding of the history and evolution of life on Earth.
