New research shows God designed an intricate system within our cells to prevent developing egg cells from inheriting harmful, mutant DNA.

Every cell in the human body, with the exception of red blood cells, contains tiny cellular machines called mitochondria that convert the sugar, fats, and proteins we eat into energy. But the DNA in a mother’s mitochondria can develop harmful mutations and lead to genetic diseases in her offspring.

New research from Adam Riess of Johns Hopkins University strengthens his previous claims that the universe could be expanding faster than it used to and be much younger than mainstream scientists believed.
