The double-fanged adolescence of saber-toothed cats

April 30, 2024

The fearsome, saber-like teeth of Smilodon fatalis — California's state fossil — are familiar to anyone who has ever visited Los Angeles' La Brea Tar Pits, a sticky trap from which more than 2,000 saber-toothed cat skulls have been excavated over more than a century.

Though few of the recovered skulls had sabers attached, a handful exhibited a peculiar feature: the tooth socket for the saber was occupied by two teeth, with the permanent tooth slotted into a groove in the baby tooth.

Junk DNA in birds may hold key to safe, efficient gene therapy

February 20, 2024

The recent approval of a CRISPR-Cas9 therapy for sickle cell disease demonstrates that gene editing tools can do a superb job knocking out genes to cure hereditary disease. But it's still not possible to insert whole genes into the human genome to substitute for defective or deleterious genes.

A new technique that employs a retrotransposon from birds to insert genes into the genome holds more promise for gene therapy, since it inserts genes into a "safe harbor" in the human genome where the insertion won't disrupt essential genes or lead to cancer.

Retrotransposons, or...
