Soon after she received the treatment, Karen Koehler’s brain swelled. Her blood pressure plummeted. As she fell into a coma, her husband and sister sat at her bedside — urging the doctors to keep pushing her farther along the razor’s edge between life and death.
Koehler was undergoing a promising — and terrifying — experimental therapy that her oncologists hoped could rid her body of cancer entirely. It’s called CAR-T therapy, and it works by engineering the patient’s own immune cells to attack cancer.
One of the hallmarks of CAR-T: It has to nearly kill you if it’s going to save you.
The treatment induces such sudden and severe side effects that it can take a small army of top specialists to keep patients alive while their newly engineered immune systems attack their cancer cells. The result: CAR-T remains so risky, so complex, and so difficult to manage that experts warn it’ll be years before it’s available to most patients who would stand to benefit — even though two drug makers, startup Kite Pharma and pharmaceutical giant Novartis...

            For two years, a panel of scientific experts, clinicians, and patient advocates had been hammering out ways to increase community engagement in National Institutes of Health-funded science. When they presented their road map to the NIH Director Jay Bhattacharya last...

[OHSU News/Christine Torres Hicks]
On September 30th, a team of 21 scientists from Oregon Health & Science University (OHSU) published a significant paper in Nature Communications, with a scientifically accurate but, to many, somewhat abstruse headline:
Induction of experimental cell division to generate cells with reduced chromosome ploidy
The lead authors were Shoukhrat Mitalipov, recently described here as “a push-the-envelope biologist,” and his long-term colleague Paula Amato. (Recall that in July the pair had co-published with...

            Before dawn on a March morning, Doug Whitney walked into a medical center 2,000 miles from home, about to transform from a mild-mannered, bespectacled retiree into a superhuman research subject.
First, a doctor inserted a needle into his back to...

            Consider, if you will, the translucent blob in the eye of a microscope: a human blastocyst, the biological specimen that emerges just five days or so after a fateful encounter between egg and sperm. This bundle of cells, about the size of...
