Your dog or cat’s DNA is an open book. DNA tests tell people about their pet’s breed and attempt to predict things about its behavior and health.
Lots of companies will now test DNA from people and their pets. How do these gene-sequencing techniques work? We explain.
Dog and cat breeds can look very different from one another. How does it happen? Combinations of tiny genetic tweaks.
A host of new human trials are using a gene-editing tool known as CRISPR to treat genetic diseases — from sickle cell and cancers to a blinding eye disorder.
Subtle defects in T cell function alter rodents’ microbiome and fat absorption, providing hints of what might also be going on in people.
Diseases threaten important food crops like cocoa beans, wheat and citrus. Scientists are working to understand these infections — and fight back.
A new weapon could help fight mosquitoes that spread malaria. It’s an engineered fungus that infects the insects — then kills them with a spider poison.
Researchers discovered a previously unknown population of Ice Age people who crossed the Asia-North America land bridge.
Animals shed DNA into their environment. Usually scientists find it in water or soil. Now, two teens have figured out how to capture this “environmental DNA” from air.
