The Download: ice-melting robots, and genetically modified trees

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.

Life-seeking, ice-melting robots could punch through Europa’s icy shell

At long last, NASA’s Europa Clipper mission is on its way. It launched on October 14 and is now en route to its target: Jupiter’s ice-covered moon Europa, whose frozen shell almost certainly conceals a warm saltwater ocean. When the spacecraft gets there, it will conduct dozens of close flybys in order to determine what that ocean is like and, crucially, where it might be hospitable to life.

Europa Clipper is still years away from its destination—it is not slated to reach the Jupiter system until 2030. But that hasn’t stopped engineers and scientists from working on what would come next if the results are promising: a mission capable of finding evidence of life itself. Read the full story.

GMOs could reboot chestnut trees

Living as long as a thousand years, the American chestnut tree once dominated parts of the Eastern forest canopy, with many Native American nations relying on them for food. But by 1950, the tree had largely succumbed to a fungal blight probably introduced by Japanese chestnuts.

As recently as last year, it seemed the 35-year effort to revive the American chestnut might grind to a halt. Now, American Castanea, a new biotech startup, has created more than 2,500 transgenic chestnut seedlings— likely the first genetically modified trees to be considered for federal regulatory approval as a tool for ecological restoration.

The big story

How covid conspiracies led to an alarming resurgence in AIDS denialism

August 2024

Several million people were listening in February when Joe Rogan falsely declared that “party drugs” were an “important factor in AIDS.” His guest on The Joe Rogan Experience, the former evolutionary biology professor turned contrarian podcaster Bret Weinstein, agreed with him.

Speaking to the biggest podcast audience in the world, the two men were promoting dangerous and false ideas—ideas that were in fact debunked and thoroughly disproved decades ago.

These comments and others like them add up to a small but unmistakable resurgence in AIDS denialism—a false collection of theories arguing either that HIV doesn’t cause AIDS or that there’s no such thing as HIV at all.

These claims had largely fallen out of favor until the coronavirus arrived. But, following the pandemic, a renewed suspicion of public health figures and agencies is giving new life to ideas that had long ago been pushed to the margins. Read the full story.
