Download: Three parent baby cases, and the solar balloon experiment

The three-parent baby system may put babies at risk of serious illness.

The first baby born using the controversial procedure had three genetic parents when he was born in 2016. The baby boy inherited most of his DNA from his mother and father, but a small amount from a third person.

The idea was to prevent the child from inheriting a deadly disease. His mother carried genes for the disease in the mitochondria. Altering these genes from a donor-third genetic parent can prevent the child from developing. The strategy seems to be working.

But it may not always be successful. MIT Technology Review shows two cases of babies conceived with the procedure that scientists call “reversals.” In both cases, the amount of mitochondrial genes from the child’s mother increased over time, from less than 1% in both fetuses to around 50% in one child and 72% in the other.

Fortunately, both children were born without the genes for mitochondrial disease. But the scientists behind the work believe that about one in three babies born with the three-parent technique may inherit their mothers’ mitochondrial genes.

For babies born to people with disease-causing mutations, this can spell disaster—leaving them with devastating and deadly diseases. Read the full story.

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

Last September, researchers in England released a high-altitude weather balloon that released a few hundred grams of sulfur dioxide into the stratosphere, which could be scientific in the field of solar geoengineering, MIT Technology Review reports.

In theory, spraying sulfur dioxide into the stratosphere would reflect more sunlight into space to mitigate global warming, mimicking the cooling effect that occurs after major volcanic eruptions. Concerns about potential unintended consequences, along with other issues, are highly controversial.

But the UK effort was not a geoengineering experiment. Instead, the stated goal was to evaluate a low-cost, controllable, renewable balloon system. There are those who are concerned that the effort went ahead without a broad public announcement and without prior cooperation. Read the full story.

The 11th Breakthrough Technology Flight of 2023 began

It’s official—after more than a month of open voting, hydrogen airplanes are the readers’ choice for the 11th item on the 2023 Breakthrough Technologies list.

There is also some interesting 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 aircraft powered by hydrogen fuel cells.

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

The big story

We’re getting a better understanding of AI’s true carbon footprint.

November 2022

Large language models have a dirty secret: they require huge amounts of energy to train and run. But how big the carbon footprints of these models are is still a bit of a mystery. But AI startup Hug Face believes he has come up with a new, accurate way to calculate it.

The startup’s work could be a step toward getting more concrete information from tech companies about the carbon footprint of their AI products — and it comes as experts are calling for the sector to do a better job of assessing AI’s environmental impact. Read the full story.
