The Download: hydrogen-powered planes, and abortion pills

Hydrogen-powered planes take off with startup's test flight

The news: In a record trip for low-carbon aviation, a startup has completed a test flight of a 19-seat aircraft powered in part by hydrogen fuel cells. ZeroAvia, a leader in developing hydrogen-electric systems for planes, flew its largest plane to date for around 10 minutes after taking off from Cotswold Airport in the UK.

How they did it: During the flight, the plane's left engines were powered by a combination of hydrogen fuel cells and batteries, while the right side relied on the fossil fuel kerosene.

Why it matters: It's a significant step for zero-emissions flight. Aviation accounts for about 3% of global greenhouse gas emissions, and the industry is growing. Hydrogen fuel cells represent one possible route that might reduce emissions from the aviation industry-and ZeroAvia is confident it's on track for a commercial launch in 2025. Read the full story.

TR10: Abortion pills via telemedicine

Access to abortion care has narrowed dramatically in the US post-Roe. But there's been one big shift in the other direction: the ability to access care without leaving home.

In 2021, during the pandemic, the US Food and Drug Administration temporarily allowed healthcare providers to mail patients two pills-mifepristone and misoprostol-that, when taken together, can induce an abortion.

A year later, the US Supreme Court ruled that abortion is not a constitutional right, and nonprofits and startups stepped up to meet the surging demand for the pills. Access to medication abortion is not a solved problem. However, the foresight of these organizations brought care to many at a critical time. Read about the shifting stakes of obtaining abortion pills over telemedicine.

Abortion pills via telemedicine is one of MIT Technology Review's 10 Breakthrough Technologies of 2023. Read over the rest of the list, and vote in our poll to decide what our final 11th technology should be.

How CRISPR is making farmed animals bigger, stronger, and healthier

The CRISPR gene-editing tool has been making headlines for the last 10 years, since scientists showed it could be used to easily alter the genome of a living organism.

But while the technology could eventually revolutionize healthcare for humans, it could also transform farming, including aquaculture. Researchers have inserted an alligator gene into catfish-not to make these fish more alligator-like, but to make them more resistant to disease.

This isn't the first time scientists have tried to tweak the genomes of farmed animals. But although gene-editing tools like CRISPR should allow them to fast-forward the process, don't expect to find CRISPR-engineered animals on supermarket shelves just yet. Read the full story.

Inside the race to make human sex cells in the lab

August 2022

The way we make babies could be about to change. Maybe.

An embryo forms when sperm meets egg. But what if we could start with other cells-if a blood sample or skin biopsy could be transformed into artificial" sperm and eggs? What if those were all you needed to make a baby?

That's the promise of a radical approach to reproduction. Scientists have already created artificial eggs and sperm from mouse cells and used them to create mouse pups. Artificial human sex cells are next.

The problem is actually getting there and-maybe even harder-untangling the knot of ethical issues that will come up along the way. Read the full story.
