Elephant genes could hold the key to avoiding cancers, study

Tumors result from an accumulation of gene mutations that increase risk with age. However, unlike humans, elephants seem to buck this trend. Despite their large body size and a life expectancy comparable to humans, cancer mortality in elephants is estimated at less than 5% (rather than up to 25% in humans). Elephants have 20 copies…

Sea dragons’ genes give clues to their distinctive looks

Credit: Shutterstock Even with plenty of fish in the sea, sea dragons stand out from the crowd. The funky, fabulous fish are bedecked with ruffly leaf-like adornments. Their spines are kinked. They’re missing their ribs and their teeth. And the responsibility of pregnancy is taken on by the males. By sequencing the genomes of two…

Ancient Genes for Symbiosis Hint at Mitochondria’s Origins

A white blood cell ingests rod-shaped bacteria (pink) in this micrograph. Some scientists are using the apparent age of this process, known as phagocytosis, to deduce when complex cells might have acquired mitochondria.SPL/Science SourceOnce, long ago, the only players in the grand drama of life, predation and death were invisibly small and simple cells.
