The three-parent baby technique could put babies at risk of serious illness

When the first baby born with a controversial procedure that meant he had three genetic parents was born in 2016, it made headlines. The baby boy inherited most of his DNA from his mother and father, but also had a small amount from a third person.

The idea was to avoid the baby inheriting a deadly disease. His mother carried genes for a disease in her mitochondria. Swapping these with genes from a donor – a third genetic parent – could prevent the baby from developing it. The strategy seemed to be working.

But it may not always be successful. The MIT Technology Review can reveal two cases in which babies conceived through the procedure have shown what scientists call a “reversion.” In both cases, the percentage of mitochondrial genes from the child’s mother has increased over time, from less than 1% in both fetuses to about 50% in one baby and 72% in another.

Fortunately, both babies were born to parents without genes for mitochondrial disease. But the scientists behind the work believe that around one in five babies born using the three-parent technique could end up inheriting high levels of their mother’s mitochondrial genes.

For babies born to people with disease-causing mutations, this could spell disaster – leaving them with devastating and potentially fatal diseases. Read the full story.

Researchers launched a test flight of solar geoengineering in the UK last year

Last September, researchers in the United Kingdom launched a high-altitude weather balloon that released a few hundred grams of sulfur dioxide into the stratosphere, a possible scientific first in the field of solar geoengineering, according to MIT Technology Review.

In theory, spraying sulfur dioxide into the stratosphere could mimic a cooling effect that occurs in the wake of large volcanic eruptions, reflecting more sunlight into space in an effort to ease global warming. It is highly controversial given concerns about possible unintended consequences, among other issues.

But the UK’s effort was not an experiment in geoengineering. Rather, the stated goal was to evaluate a low-cost, controllable, recoverable balloon system. And some are concerned that the effort went ahead without broader public disclosures and commitment up front. Read the full story.

The 11th breakthrough technology of 2023 begins flight

It’s official—after over a month of open voting, hydrogen airplanes are our readers’ choice for the 11th item on our list of breakthrough technologies for 2023!

There also happens to be some exciting news about hydrogen planes this week. Startup Universal Hydrogen is planning a test flight today. If all goes according to plan, it will be the largest hydrogen fuel cell aircraft yet to fly.

But even if the test flight is successful, there is still a long way to go before cargo or passengers can board a hydrogen-powered plane. Read the full story.

The big story

We have a better idea of ​​the true carbon footprint of AI

November 2022

Large language models have a dirty secret: they require huge amounts of energy to train and run. But it’s still a bit of a mystery just how big the carbon footprints of these models really are. But AI startup Hugging Face believes it has found a new, more accurate way to calculate it.

The startup’s work could be a step toward more realistic data from tech companies about the carbon footprint of their AI product — and comes at a time when experts are calling for the industry to do a better job of assessing its environmental impact. artificial intelligence. Read the full story.
