Strains - not species - of gut bacteria may provide better insights into the microbiome

Every day, the billions of bacteria that inhabit your digestive system change; the food you eat, medications you take, and germs you're exposed to make some bacteria flourish more than others.

Researchers discover transposon-encoded RNA-guided nucleases with potential for genome editing

Researchers seeking to understand the origins of CRISPR-Cas9 systems have uncovered a class of transposon-encoded RNA-guided nucleases, which they dubbed "OMEGA," that could be harnessed for genome editing in human cells.

Scientists identify new Salmonella proteins

Salmonella are bacteria that can cause food poisoning with severe diarrhea. If they penetrate from the intestine into the blood system, this can lead to sepsis, life-threatening inflammatory reactions in the entire organism.

Protein aggregates may play protection role against toxic stresses

Protein aggregates have a bad reputation in conditions such as Alzheimer’s disease and Parkinson’s disease, but in bacteria, inheritance of aggregates by daughter cells may help protect against the same toxic stresses that triggered them in parental cells, according to a new study publishing 28 August in the open access journal PLOS Biology, by Sander Govers, Abram Aertsen, and colleagues at KU Leuven, Belgium.

Ribosomes found to be cause of somatic cell pluripotency

In 2012, a Japanese research group discovered that human skin cells acquire pluripotency when introduced to lactic acid bacteria. Now, the same group of researchers have found that the cause of somatic cell conversion into pluripotent stem cells is the ribosome, a protein synthesizing cellular organelle.

Groundbreaking research findings could lead to potential new treatments for Crohn’s disease

A Case Western Reserve University School of Medicine-led team of international researchers has for the first time identified a fungus as a key factor in the development of Crohn's disease.

New study analyzes evolution of epigenetic mechanisms from bacteria to humans

After the emergence of single-celled organisms some billions of years ago, nature started experimenting with how to diversify gene function without changing the sequence of the DNA, such that the blue print remains conserved, but allows gene products to have different functions.

Study offers new insights into construction of nuclear pores in nuclear envelope

In a recent study, a team of researchers led by Alwin Köhler at the Max F. Perutz Laboratories (MFPL) belonging to the University of Vienna and the Medical University of Vienna offer new insights into how nuclear pores are constructed in the nuclear envelope.

Scientists use novel metagenomic approaches to characterize microbial communities that reside in human gut

The gut microbiota contains a vast number of microorganisms from all three domains of life, including bacteria, archaea and fungi, as well as viruses. These interact in a complex way to contribute towards both health and the development of disease - interactions that are only now being elucidated thanks to the application of advanced DNA sequencing technology in this field.

Studies indicate that harvested rainwater frequently harbors pathogens

South Africa has been financing domestic rainwater harvesting tanks in informal low-income settlements and rural areas in five of that nation's nine provinces. But pathogens inhabit such harvested rainwater, potentially posing a public health hazard, especially for children and immunocompromised individuals, according to a team from the University of Stellenbosch.
