Scandinavian gene pool development via DNA analysis

The complex relationships between geography, ancestry, and gene flow in Scandinavia are resolved in a new study based on 297 ancient Scandinavian genomes that were analyzed along with the genomic data of 16,638 modern Scandinavians.

Researchers expand the known defensive abilities of CRISPR–Cas systems

Viruses can infect bacteria and archaea, just as they can humans. These microbes have evolved their own immune defense mechanisms to combat their pathogens. Bacterial defenses, like CRISPR-Cas systems, contain a variety of proteins and functions that aid bacteria in protecting themselves from foreign intruders.

What are the implications of microbiome-directed measures to treat type 2 diabetes?

According to preliminary findings from an ongoing, prospective study headed by Cedars-Sinai researchers, one type of bacteria seen in the gut might contribute to the development of Type 2 diabetes, while another might guard against the condition.

The detrimental effects of alcohol consumption during pregnancy

For the first time, researchers at the University of Helsinki in Finland examined the effects of prenatal alcohol exposure on the epigenome and gene function of the placenta. The epigenome is a molecular coating on a DNA strand that controls how genes are expressed.
