CRISPR

Thylacines, or Tasmanian tigers, have been extinct for nearly 100 years. But scientists say gene-editing technology could bring back this lost species.

These viruses were found in hot springs and the deep sea.

The method has not yet been tested on animals or people.

The glands had no openings so they swelled up like "balloons."

The gene-editing tool can precisely snip DNA from the genome.

Chinese researcher He Jiankui, who created the world's first genome-edited twins, has been sentenced to three years in prison.

As the decade closes, we look at the science stories that made the biggest splash over the past 10 years.

Preliminary data from an innovative clinical trial suggests CRISPR could be safe for use in cancer therapy.
