Study reveals lower transfer of protective SARS-CoV-2 antibodies via the placenta

Recent analyses indicate that pregnant women and newborns may face elevated risks of developing more severe cases of COVID-19 following SARS-CoV-2 infection.

Researchers use different colors of light to control gut bacteria genes

Baylor College of Medicine researcher Meng Wang had already shown that bacteria that make a metabolite called colanic acid (CA) could extend the lifespan of worms in her lab by as much as 50%, but her collaboration with Rice University synthetic biologist Jeffrey Tabor is providing tools to answer the bigger question of how the metabolite imparts longer life.

Researchers investigate microbiome-mediated therapies for aging and health span

Texas Biomedical Research Institute Associate Professor Corinna Ross, PhD, is a principal investigator on a $3.38 million National Institutes of Health multi-investigator grant to study "microbiome-mediated therapies for aging and healthspan" in marmosets, which are small monkeys native to South America and are becoming increasingly more important in aging and infectious disease research.

Researchers measure bacterial and host gene expression profiles in mouse model

The bacteria Streptococcus pneumoniae colonizes the nasopharynx and can cause pneumonia. Then, it can spread from the lungs to the bloodstream and cause organ damage.

Expanded biodiversity infrastructure is crucial for pandemic preparedness

When you imagine a visit to a natural history museum, the first thing that springs to mind could be dinosaur bones or taxidermized animals.

Study investigates potential link between COVID-19 spread and atmospheric pollutants

The spread of SARS-CoV-2, the coronavirus responsible for the current pandemic outbreak, has been speculated to be linked to short-term and long-term atmospheric pollutants exposure, mainly particulate matters (PMs).

TGen identifies genetic target that could help explain the variation in COVID-19 effects

The Translational Genomics Research Institute (TGen), an affiliate of City of Hope, has identified a specific genetic target that could help explain the tremendous variation in how sick those infected with COVID-19 become.

Study: Fungi have proteins that allow them to sense consumable things

According to a new study, the same proteins responsible for enabling human senses, like smell, also enable some fungi to sense things they can consume.

Researchers discover genetic variants of host proteins involved in SARS-CoV-2 infection

Like all viruses, the novel coronavirus is dependent on help from the human host cell. Proteins are the functional units of the cell and enable the virus to enter the host cell or help the virus to replicate.

Study investigates the role of soil and root microbes in Huanglongbing disease

A UC Riverside-led team is looking at tiny underground microorganisms for a way to prevent a huge problem -- Huanglongbing, a disease for which there is no cure that has decimated citrus orchards worldwide.

Gene expression database sheds light on pneumococcal infection

Researchers at the University of Maryland School of Medicine published one of the most comprehensive analyses of how genes get expressed during infection (known as a transcriptome).

Study: Eating avocado as part of daily diet can help improve gut health

Eating avocado as part of your daily diet can help improve gut health, a new study from University of Illinois shows. Avocados are a healthy food that is high in dietary fiber and monounsaturated fat. However, it was not clear how avocados impact the microbes in the gastrointestinal system or "gut."

Researchers describe two new fungal species

University of Copenhagen researchers have found and described two fungal species for the first time. The fungi infect adult flies and subsequently create a hole in the abdomen of their hosts' bodies.

Biochemical methods reveal signal transduction mystery inside human pathogen

In order to adapt to the changing environment, bacteria must quickly transform extracellular information into appropriate intracellular reactions. Two component system (TCS) is the main signal transduction protein in prokaryotic cells to transform environmental stimuli into cellular responses.

Microbes act as efficient microscopic fuel cell, shows study

By borrowing nature's blueprints for photosynthesis, Cornell University bioengineers have found a way to efficiently absorb and store large-scale, low-cost renewable energy from the sun - while sequestering atmospheric carbon dioxide to use later as a biofuel.

New gene therapy approach can improve uterine blood flow in placental insufficiency

A new study identified an adenovirus gene therapy vector carrying a VEGF isoform. It can improve uterine blood flow in placental insufficiency, as reported in the peer-reviewed journal Human Gene Therapy.

Researchers identify new therapeutic target to fight COVID-19 disease

In COVID-19 patients with severe lung disease, targeting the endothelial cells—that is, cells comprising the blood vessel wall, which control oxygen exchange between the bloodstream and airways—may be an innovative strategy to restore normal function of the lungs.

Scientists identify biosynthetic genes involved in the production of usnic acid in lichens

Scientists from the Faculty of Pharmacy at the Complutense University of Madrid have headed an international study that has successfully detected a sequence of biosynthetic genes that play a key role in the synthesis of usnic acid in lichen—a kind of compound that exhibits antioxidant, antiviral, antibacterial, anticancer, and neuroprotective activity.
