MIT Technology Review's newsletter The Download introduces its last print edition of 2026, the Impossible issue. The editors argue that daring ideas matter because they show what technology is supposed to do: make life better, safer, healthier and more joyful. The issue explores bold attempts to make synthetic blood, build cities on the moon and achieve cognitive immortality. It also investigates AI's ability to say no, a bionic eye that can restore sight, and high hopes for blended meat.
The newsletter also highlights several stories. Astrolab's upcoming FLIP lunar rover is slated to carry a computer capable of running large language models to the moon as early as next month, testing whether LLMs can enable greater autonomy in an extreme environment marked by temperature swings and intense cosmic radiation. Separately, scientists studying a 2013 lightning fire that burned nearly 35,000 acres in Alaska's Denali National Park are learning how fires reshape permafrost and carbon storage, with worrying signs about cascading climate feedback.
A narrated feature examines a 26,000-word blog post by Nick Cammarata, a researcher at AI startup Goodfire, who claims that LLMs may be far easier to understand, monitor and control than previously thought. If true, the claim would be a huge deal, though not everyone is convinced.
The Must-Reads section rounds out the edition with technology news, including reports that Elon Musk ordered the recent Starlink slowdown in Ukraine, a restriction that hampered drone strikes and air defences and sparked confusion in Washington over who authorised it.
