Scientists are using genetic engineering and cloning to try to bring back extinct species or save endangered ones. Here’s how and why.
By tweaking just three genes in a common lab plant, scientists have mimicked one of nature’s most impressive mathematical patterns.
Some of these tweaks to DNA, however, may have played a role in brain evolution.
The price of not vaccinating nearly everyone across the world could be a longer pandemic and more troubling variants of the new coronavirus.
An egg or a sperm cell contains half of the normal genes an organism needs. They fuse together to form a new individual.
Little diversity in genetic databases makes precision medicine hard for many. One historian proposes a solution, but some scientists doubt it’ll work.
Identical twins may not be exactly identical. Mutations may arise early in development that account for tiny genetic differences between siblings.
The variant may spread more easily from person to person. That could make continuing to wear masks all the more important, experts say.
Onward’s dumpster-diving unicorns seem like an impossibility. But scientists have some ideas about how unicorns could become real.
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.
