Your daily dose of what's up in emerging technology By Rhiannon Williams • 11.1.23 | | | Hello! Today: we asked prominent figures in technology what they thought were the biggest problems facing us—check out what they had to say. Plus: new engineered-cell therapies are showing promise for fighting certain types of cancer, and why China is betting big on gene therapies. | | What are the hardest problems in tech we should be more focused on as a society? Technology is all about solving big thorny problems, yet one of the hardest things is knowing where to focus our efforts. There are so many urgent issues facing the world. Where should we even begin? We asked dozens of people to identify what problem at the intersection of technology and society that they think we should focus more of our energy on. We queried scientists, journalists, politicians, entrepreneurs, activists, and CEOs. Some broad themes emerged: the climate crisis, global health, creating a just and equitable society, and AI all came up frequently. There were plenty of outliers, too, ranging from regulating social media to fighting corruption. Read the full list to find out what they said.
This story is from our most recent print issue of MIT Technology Review, which is all about society's hardest problems, and how we should tackle them. If you don't subscribe already, sign up now to get future issues when they land.
| | Innovative new cell therapies could finally get at tough-to-target cancers The news: A biotech company is making headway in leveraging patients' own immune systems to destroy cancerous cells in solid tumors. While researchers have recently had success in treating some hard-to-treat blood cancers with engineered T cells, solid tumors, which make up the vast majority of cancer diagnoses, have proved much more difficult. How they did it: The technicians harvested T cells, which help the body fight infections, from a patient's blood, before genetically engineering the cells to carry a receptor called a chimeric antigen receptor, or CAR, which can bind to a protein on the surface of the cancer cell. Next they grow these engineered cells in the lab, then reinfuse them back into the body. When the cells encounter the protein they're designed to recognize, they activate and start destroying the cancer cells. The results: BioNTech treated 44 people with solid tumors with varying doses of CAR T cells and, in some cases, a vaccine to help boost the therapy. Among the 38 people for whom there was enough data to assess how well the treatment worked, 45% responded, meaning their tumors shrank or disappeared altogether.

During the trial, five young patients received injections of a virus that added replacement DNA to the hair cells in their inner ear. Four of them have since developed the ability to hear. But while this is a phenomenal step forward in using gene therapy to restore human senses, it faces the same challenging financial calculations that plague a lot of niche medical solutions. One thing that may help is generous government subsidies. It's one area that Chinese authorities also may be more willing to spend on given the fact that, at least in this application of gene therapy, the country has raced ahead of its competitors in the West.

"We need to stop thinking about making AI safe, and start thinking about making safe AI." —Stuart Russell, a professor of computer science at University of California, tells the Guardian how he wants our thinking on artificial intelligence to shift. | | | The big story |  | | One city's fight to solve its sewage problem with sensors April 2021 In the city of South Bend, Indiana, wastewater from people's kitchens, sinks, washing machines, and toilets flows through 35 neighborhood sewer lines. On good days, just before each line ends, a vertical throttle pipe diverts the sewage into an interceptor tube, which carries it to a treatment plant where solid pollutants and bacteria are filtered out. As in many American cities, those pipes are combined with storm drains, which can fill rivers and lakes with toxic sludge when heavy rains or melted snow overwhelms them, endangering wildlife and drinking water supplies. But city officials have a plan to make its aging sewers significantly smarter.
