(Phys.org) —One of the biggest threats facing amphibian species is the disease chytridiomycosis, which is caused by a fungus known as Batrachochytrium dendrobatidis (Bd). An understanding of the evolutionary history of ...
(Phys.org)—The traditional genome sequencing process requires thousands of cells (or more) to provide sufficient DNA, and this means that variations that are only present in a small number of cells―such as early cancer ...
Just like the wrong ingredients can spoil a cake, so too can the wrong ingredients spoil the results in biomedical research. The difference is that the latter involves years of work, financial and personal investment and ...
