The Download: digital twins, and where AI data really comes from
This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology. Digital twins of human organs are here. Theyre set to transform medical treatment. Steven Niederer, a biomedical engineer at the Alan Turing Institute and Imperial College London, has a cardboard box filled with 3D-printed hearts. Each of them is modeled on the real heart of a person with heart failure, but Niederer is more interested in creating detailed replicas of peoples hearts using computers. These digital twins are the same size and shape as the real thing. They work in the same way. But they exist only virtually. Scientists can do virtual surgery on these virtual hearts, figuring out the best course of action for a patients condition.After decades of research, models like these are now entering clinical trials and starting to be used for patient care. The eventual goal is to create digital versions of our bodiescomputer copies that could help researchers and doctors figure out our risk of developing various diseases and determine which treatments might work best.But the budding technology will need to be developed very carefully.

Reams and reams of data are needed to train algorithms to do what we want, and what goes into the AI models determines what comes out. But heres the problem: AI developers and researchers dont really know much about the sources of the data they are using. The Data Provenance Initiative, a group of over 50 researchers from both academia and industry, wanted to fix that. They wanted to know, very simply: Where does the data to build AI come from? Their findings, shared exclusively with MIT Technology Review, show a worrying trend: AI's data practices risk concentrating power overwhelmingly in the hands of a few dominant technology companies.

Global greenhouse-gas emissions hit a new high, and this year is also on track to be the warmest on record. Global climate talks fell flat, and disasters from wildfires to hurricanes are being made worse by climate change. But among all that (very real) negative news, there was some good, too: We saw progress cutting back on the most polluting fossil fuels, cheaper and better technologies for combating climate change, and a continuous global effort to address the problem. So as we near the end of 2024, lets take a moment to look back on some of the bright spots. Casey Crownhart This story is from The Spark, our weekly climate and energy newsletter.

The big story Future space food could be made from astronaut breath May 2023 The future of space food could be as simpleand weirdas a protein shake made with astronaut breath or a burger made from fungus. For decades, astronauts have relied mostly on pre-packaged food during their forays off our planet. With missions beyond Earth orbit in sight, a NASA-led competition is hoping to change all that and usher in a new era of sustainable space food. To solve the problem of feeding astronauts on long-duration missions, NASA asked companies to propose novel ways to develop sustainable foods for future missions. Around 200 rose to the challengecreating nutritious (and outlandish) culinary creations in the process. Read the full story.
