In vitro fertilization has exploded across America. The number of babies born through assisted reproductive technologies — most of them via IVF — jumped 45%from 2013 to 2022.
A more recent part of the surge is elective IVF — still a small share of overall IVF cycles — in which people who could conceive naturally choose IVF to screen embryos for genetic traits linked to cancer risk, IQ, height and more.
Why it matters: It's becoming big business, with screening companies promising "generational health." But doctors warn that the science behind embryo scoring for complex conditions is shaky — and could push would-be parents toward major medical and emotional decisions based on unproven data.
Artificial intelligence is struggling to understand accented English and non-standard dialects, creating problems that can cascade into biased hiring, grading or clinical records.

The big picture: The new study represents one of the most substantive findings on long COVID from the Researching COVID to Enhance Recovery (RECOVER) project, launched by the NIH in 2021.
