DHS plans to collect biometric data from migrant children “down to the infant”
The US Department of Homeland Security (DHS) plans to collect and analyze photos of the faces of migrant children at the border in a bid to improve facial recognition technology, MIT Technology Review can reveal.
The technology has traditionally not been applied to children, largely because training data sets of real children’s faces are few and far between, and consist of either low-quality images drawn from the internet or small sample sizes with little diversity. Such limitations reflect the significant sensitivities regarding privacy and consent when it comes to minors.
In practice, the new DHS plan could effectively solve that problem. But, beyond concerns about privacy, transparency, and accountability, some experts also worry about testing and developing new technologies using data from a population that has little recourse to provide—or withhold—consent.

What Japan’s “megaquake” warning really tells us
On August 8, at 16:42 local time, a magnitude-7.1 earthquake shook southern Japan. The temblor, originating off the shores of mainland island of Kyūshū, was felt by nearly a million people across the region, and initially, the threat of a tsunami emerged. But only a diminutive wave swept ashore, buildings remained upright, and nobody died. The crisis was over as quickly as it began.
But then, something new happened. The Japan Meteorological Agency, a government organization, issued a ‘megaquake advisory’ for the first time. It was in part issued because it is possible that the magnitude-7.1 quake is a foreshock – a precursory quake – to a far larger one, a tsunami-making monster that could kill a quarter of a million people.
The good news, for now, is that scientists think it is very unlikely that that magnitude-7.1 quake is a prelude to a cataclysm. But the slim possibility remains that it was a foreshock to something considerably worse. Read the full story.

The US government is still spending big on climate
Friday marks two years since the US signed the landmark Inflation Reduction Act (IRA) into law. In that time we’ve seen an influx of investment from the federal government and private businesses alike.
The government has already spent hundreds of billions of dollars, and there’s much more to come. And this money is starting to make a big difference in the climate tech sector. But where is it all going? Read our story to find out.

The big story
The search for extraterrestrial life is targeting Jupiter’s icy moon Europa
Europa, Jupiter’s fourth-largest moon, is nothing like ours. Its surface is a vast saltwater ocean, encased in a blanket of cracked ice, one that seems to occasionally break open and spew watery plumes into the moon’s thin atmosphere.
For these reasons, Europa captivates planetary scientists. All that water and energy—and hints of elements essential for building organic molecules —point to another extraordinary possibility. Jupiter’s big, bright moon could host life.
And they may eventually get some answers. Later this year, NASA plans to launch Europa Clipper, the largest-ever craft designed to visit another planet. The $5 billion mission, scheduled to reach Jupiter in 2030, will spend four years analyzing this moon to determine whether it could support life. Read the full story.
