Russian president Vladimir Putin and China’s Xi Jinping discussed the prospect of people living longer through transplant surgery, a claim that experts say oversimplifies a complex scientific problem. The article draws on reporting from the Checkup, MIT Technology Review’s weekly biotech newsletter, to explain that repeated organ transplants are unlikely to deliver radical lifespan extension anytime soon. Researchers do not agree on the fundamental causes or definitions of aging, so treating it as a single problem that transplants can solve mischaracterizes decades of unresolved biomedical questions.
In India, efforts are underway to replace the hazardous practice of manual scavenging with mechanical and robotic alternatives. The piece profiles the Delhi government’s program, which now involves about 200 contractors and a range of companies offering technical solutions for sewer cleaning. Although manual scavenging was outlawed in 1993, it remains widespread and dangerous. The reporting highlights personal stakes by noting that some workers, such as Jitender, grew up in families where parents performed the work, and that new technologies are framed primarily as improvements in safety and dignity for workers.
The newsletter also curates a set of technology items to watch. Key entries include accusations that a major study linking alcohol and cancer was suppressed, political controversy around embedding Artificial Intelligence tools in education, and a forthcoming Federal Trade Commission probe into the effects of Artificial Intelligence systems on children’s mental health. Other highlights note legal and industry shifts: openai will reportedly build its own chips, a startup called DeepSeek aims to develop an advanced Artificial Intelligence agent, and Warner bros has sued an image generator for using character likenesses without permission. Broader environmental and infrastructure stories are included, such as the use of rivers and lakes to cool buildings and an initiative to link US power grids to speed renewable adoption.
The newsletter closes with a profile of energy developer Michael Skelly, who continues to push for long-haul transmission lines that could move wind power across regions. Despite setbacks and a previous business closure in 2019, he argues that larger grid connections are essential to accelerate the transition from fossil fuels to renewables. The collection balances policy, human-interest, and technology beats to reflect current debates around health, labor, and infrastructure.
