New Type of Extracellular Nanoparticle Discovered - Genetic Engineering & Biotechnology News


Genetic Engineering & Biotechnology News
Exosomes are nanosized extracellular membrane vesicles that are secreted by most cell types, including cancer cells. “Proteins, genetic material (for example, mRNAs, miRNAs, lncRNAs, DNA), metabolites and lipids are selectively recruited and packaged ...

Why biodiversity might not always be such a good thing for our health - Genetic Literacy Project


Genetic Literacy Project
The entire paper is an enormous bummer,” Chelsea Wood told me during the annual meeting of the Ecological Society of America in Portland, Oregon in August [2017]. She was referring to research she had published in June as part of a special theme issue ...

Biodiversity loss can increase risk of 'extinction cascades', research ... - News-Medical.net

New research shows that the loss of biodiversity can increase the risk of "extinction cascades", where an initial species loss leads to a domino effect of further extinctions.

Genetic Drift and the Founder Effect

Arlington - United States

Brief hyperlinked article about the founder effect, the loss of genetic variation when a new colony is formed by a very small number of individuals, an extreme example of genetic drift.
