Weight-loss drugs: 10 Breakthrough Technologies 2024
One-third of US adults have obesity, a condition that makes them more susceptible to heart disease, diabetes, and cancer. However, there’s huge hope that anti-obesity drugs—including Wegovy and Mounjaro—could help address this public health crisis.
While most were originally developed to treat type 2 diabetes, these medications help people lose weight by suppressing their appetite when injected once a week at home. Success stories are everywhere online.
These drugs aren’t perfect. Many patients must stay on the drugs for life to keep the weight off, and the long-term impacts of these treatments remain unknown. Nevertheless, the treatments could improve the health of millions of people. Read the full story.

Weight-loss drugs is one of MIT Technology Review’s 10 Breakthrough Technologies for 2024. Check out the rest of the list and vote for the final 11th breakthrough—we’ll reveal the winner in April.
+ We’ve never understood how hunger works. But researchers think they’re getting closer to finally determining how this basic drive functions. Check out Adam Piore’s fascinating story.
What’s next for offshore wind
It’s a turbulent time for offshore wind power. Large groups of turbines installed along coastlines can harness the powerful, consistent winds that blow offshore, and can be a major boon to efforts to clean up the electricity supply around the world.
But in recent months, projects around the world have been delayed or even canceled as costs have skyrocketed and supply chain disruptions have swelled. These setbacks could spell trouble for efforts to cut the greenhouse-gas emissions that cause climate change.
The question is whether current troubles are more like a speed bump or a sign that 2024 will see the industry run off the road. Here’s what’s next for offshore wind power.

The end of anonymity online in China
Anonymity online in China changed drastically last year. Following many smaller decisions that make posting anonymously more difficult, the biggest blow came in October when all social media platforms in China demanded that users with large followings display their legal names.
The government and the platforms argue that the new rule can help prevent online harassment and misinformation. But their argument conveniently neglects what anonymity—a right that has existed since the invention of the internet—has afforded people online.
There’s no doubt that the introduction of the mandatory real-name rule will almost certainly lead to more strict and expansive restrictions for everyone. Perhaps the only glimmer of hope is that users all over China have not given up, and are still finding workarounds to stay anonymous. Read the full story.

The big story
The first babies conceived with a sperm-injecting robot have been born
Last spring, a group of engineers set out to test the sperm-injecting robot they’d designed. Altogether, the robot was used to fertilize more than a dozen eggs.
The result of the procedures, say the researchers, was healthy embryos—and now two baby girls, who they claim are the first people born after fertilization by a “robot.”
The startup behind the robot, Overture Life, says its device is an initial step toward automating IVF, and potentially making the procedure less expensive and far more common than it is today. MIT Technology Review has identified a half-dozen startups with similar aims. Some have roots in university laboratories specializing in miniaturized lab-on-a-chip technology.
But fully automating the process will be far from easy. Read the full story.
