Researchers from the University of Guelph in Canada have reported an astonishing discovery: that the number of chromosome sets in their bodies’ cells seems to be linked to the rate at which the species’ mitochondrial genome evolves. This is unusual because mitochondrial DNA sits in a separate genome from the chromosomes in the nucleus and…

Modern healthcare is fundamentally dependent on a constant supply of known and new drugs, making their discovery and manufacture a profitable business. The Indian pharmaceutical industry plays a key role in making drugs available globally at low prices, reflected in its projected revenue of about $130 billion by 2030. However, it largely manufactures generics that…
