A meteorite that lit the sky over Sri Lanka with a yellow and green flame when it fell to earth on Dec. 29, 2012, contains "fossilized biological structures," according to researchers in Britain, Sri Lanka, and the United States. Elaborating on claims they first made in January, the scientists are also seeking to answer critics who are skeptical of their findings.

In her new book, Frankenstein's Cat: Cuddling up to Biotech's Brave New Beasts, science journalist Emily Anthes talks about how the landscape of bioengineering has expanded since Dolly the Sheep was cloned in 1996.
