DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Gut bacteria in Hadza diet different from ours study finds

Probiotics are one of the fastest growing areas for research as well as one of the valued members in the food industry. These are healthy bacteria or friendly bacteria that are added to yogurts, drinks, and baby food in order to colonize out gut when we are taking antibiotics or are down with an intestinal infection.

Fewer disease-carrying mosquitoes live in undisturbed tropical forests, study finds

A new study by scientists from the Smithsonian, the Panamanian government, and the U.S. Environmental Protection Agency, among other institutions, concludes that conserving old-growth tropical rainforest is "highly recommended" to prevent new outbreaks of viral and parasitic mosquito-borne diseases.
