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. Inside the strange limbo facing millions of IVF embryos Millions of embryos created through IVF sit frozen in time, stored in cryopreservation tanks around the world. The number is only growing thanks to advances in technology, the rising popularity of IVF, and improvements in its success rates. At a basic level, an embryo is simply a tiny ball of a hundred or so cells. But unlike other types of body tissue, it holds the potential for life. Many argue that this endows embryos with a special moral status, one that requires special protections. The problem is that no one can really agree on what that status is. To some, theyre human cells and nothing else. To others, theyre morally equivalent to children. Many feel they exist somewhere between those two extremes. While these embryos persist in suspended animation, patients, clinicians, embryologists, and legislators must grapple with the essential question of what we should do with them. What do these embryos mean to us? Who should be responsible for them?Read the full story. Jessica Hamzelou Anthropics chief scientist on 5 ways agents will be even better in 2025 Agents are the hottest thing in tech right now. Top firms from Google DeepMind to OpenAI to Anthropic are racing to augment large language models with the ability to carry out tasks by themselves. In October, Anthropic showed off one of the most advanced agents yet: an extension of its Claude large language model called computer use. As the name suggests, it lets you direct Claude to use a computer much as a person would, by moving a cursor, clicking buttons, and typing text. Instead of simply having a conversation with Claude, you can now ask it to carry out on-screen tasks for you. Computer use is a glimpse of whats to come for agents. To learn whats coming next, MIT Technology Review talked to Anthropics cofounder and chief scientist Jared Kaplan. Here are five ways that agents are going to get even better in 2025. Melissa Heikkil & Will Douglas Heaven Small language models: 10 Breakthrough Technologies 2025 Make no mistake: Size matters in the AI world. When OpenAI launched GPT-3 back in 2020, it was the largest language model ever built. The firm showed that supersizing this type of model was enough to send performance through the roof. That kicked off a technology boom that has been sustained by bigger models ever since. But as the marginal gains for new high-end models trail off, researchers are figuring out how to do more with less. For certain tasks, smaller models that are trained on more focused data sets can now perform just as well as larger onesif not better.

The big story AI was supposed to make police bodycams better. What happened? April 2024 When police departments first started buying and deploying bodycams in the wake of the police killing of Michael Brown in Ferguson, Missouri, a decade ago, activists hoped it would bring about real change. Years later, despite whats become a multibillion-dollar market for these devices, the tech is far from a panacea. Most footage they generate goes unwatched. Officers often don't use them properly. And if they do finally provide video to the public, it usually doesnt tell the complete story. A handful of AI startups see this problem as an opportunity to create what are essentially bodycam-to-text programs for different players in the legal system, mining this footage for misdeeds. But like the bodycams themselves, the technology still faces procedural, legal, and cultural barriers to success. Read the full story.
