Researcher uses mammal DNA to zoom into the human genome with unprecedented resolution

Scientists have precisely identified base pairs of the human genome that remained consistent over millions of years of mammalian evolution, and which play a crucial role in human disease. The team analyzed the genomes of 240 mammals, including humans and identified base pairs that were 'constrained' -- meaning they remained generally consistent -- across mammal species over the course of...

Healthy teeth thanks to the 'washing machine effect'

Ruminants like cows have developed an unusual way of digesting their food: they ingest plants, give them a rough chewing and then swallow the half-chewed mash before regurgitating it repeatedly and continuing to chew. This has clear advantages: the regurgitated mushy food contains much less hard grit, sand and dust than the food that they first ingested. This protects the teeth from being ground...
