Gut microbes mitigate radiation exposure, repair GI tract

A new study by scientists at UNC Lineberger Comprehensive Cancer Center and colleagues published Oct. 30, 2020, in Science, showed that mice exposed to potentially lethal levels of total body radiation were protected from radiation damage if they had specific types of bacteria in their gut.

Toxins produced by tube-dwelling anemones have pharmacological potential, shows research

Researchers based in Brazil and the United States have completed the first-ever mapping exercise to profile the toxins produced by tube-dwelling anemones, or cerianthids, a family of marine animals belonging to the same phylum (Cnidaria) as sea anemones, jellyfish and corals.

Human immune system may play a key role in shaping the microbiome composition

The gut is an unusually noisy place, where hundreds of species of bacteria live alongside whatever microbes happen to have hitched a ride in on your lunch.

Severe ulcerative colitis linked to newly-discovered strain of oral bacteria

Severe ulcerative colitis - a form of inflammatory bowel disease (IBD) - has been linked to a newly-discovered strain of oral bacteria, a study led by UNSW Sydney has found.

Novel process turns waste materials into nutritional supplements

The shells of crustaceans and wood waste such as branches pruned from trees usually end up in landfills. These waste materials are given a new lease of life to become nutritional supplements and medicine, with the help of a novel process developed by researchers from the National University of Singapore (NUS).

Scientists use new model to develop specific cancer immunotherapy

The function of the body’s immune system is to defeat diseases by detecting foreign invaders and then mounting a response against these pathogens.

Study highlights the importance of nitrogen-fixing microorganisms in ecosystem diversity

Research at the University of Guam has shown that the decomposition of leaf litter from three threatened tree species releases nitrogen and carbon into the soil for use by other plants.

Study shows adverse effect of pH-dependent switch in protein interaction

Each biological process depends on pH in one way or another. The human body should maintain constant and specific pH regulation to function efficiently.

Study sheds new light on penicillin allergy

Scientists have reported the first strong evidence of the role of HLA-B, a crucial histocompatibility complex gene, in penicillin allergy.

Researchers develop new sensors to detect gene activity

A team of researchers have developed genetic sensors that are capable of detecting the activity of genes, instead of only the genes themselves.

Metabolite of dietary soy may decrease key risk factor for dementia

A metabolite produced following consumption of dietary soy may decrease a key risk factor for dementia--with the help of the right bacteria, according to a new discovery led by researchers at the University of Pittsburgh Graduate School of Public Health.

Researchers map the biological diversity of marine sediment

Scientists have mapped, for the first time, the biological diversity of marine sediment, which is considered as one of the largest global biomes on Earth.

New DNA-cutting tool could advance gene editing for novel treatments

Gene editing for the development of new treatments, and for studying disease as well as normal function in humans and other organisms, may advance more quickly with a new tool for cutting larger pieces of DNA out of a cell's genome, according to a new study by UC San Francisco scientists.

Cheese-ripening bacteria respond to volatile gases produced by fungi

Scientists have discovered that fungi use many ways to interact with bacteria and one of these methods is through the smells emitted by cheese.

Researchers develop model to encode established biochemical principles at cellular level

The most important components for the functioning of a biological cell are its proteins. As a result, protein production is arguably the most important process for cell growth. The faster the bacterial growth rate, the faster protein synthesis needs to take place.
