2018 closed with hubbub surrounding the purported birth of babies whose genomes had been edited using CRISPR. What will 2019 hold for CRISPR’s use in humans?

The recent discovery of 17 people who have inherited maternal and paternal lines of mitochondrial DNA has major ramifications for medical and ancestry research.

Despite a premature and ethically sketchy claim of genome editing in twin girls, an outright prohibition could blunt promising, responsible progress.

Newly developed techniques could propel a field already advancing rapidly to complement modern medicine.

Data don’t support many direct-to-consumer products, from telomere assessments to bespoke diets based on genetic sequences.

The use of pronuclear transfer to treat infertility must first be backed by evidence it can work in cases where parents seek to avoid mitochondrial mutations.
