In the coming weeks, a volunteer in Boston, Massachusetts, will be the first to test a new treatment that could end up creating a second liver in the body. And that’s just the beginning—in the following months, other volunteers will be testing doses that could leave them with up to six livers in their bodies.
The company behind the treatment, LyGenesis, hopes to save people with devastating liver disease who are ineligible for transplants. Their approach is to inject liver cells from a donor into patients’ lymph nodes, which could result in entirely new miniature organs. These small livers should help compensate for an existing disease. This approach appears to work for mice, pigs, and dogs. Now we will find out if it works in people. Read the full story.

The most popular content on Facebook belongs to trash
The most viewed Facebook post in the last quarter was 69 jokes, and it included reposted clips from an episode of the TV show Family Feud. The post, which was originally on Instagram Reel, has garnered more than 52 million views on Facebook, according to Meta’s quarterly report on the most widely viewed content on the US platform. It was just one of the many spam reposts that appeared on the Meta’s own list of top content on the platform.
This quarterly report, first launched a year ago, was created in part so Meta can tell the story it wants to tell about Facebook: that its users aren’t constantly bombarded with extreme political content. But in trying to do that, show one more thing: The most popular content on Facebook is often horrific, recycled generic memes. Read the full story.

Scientists create artificial mouse embryos with advanced brains
news: Recently created mouse embryos from stem cells in vitro show more brain development than any previously created artificial mouse embryos. While others made mouse embryos from stem cells, none reached the point where the entire brain, including the anterior part, began to develop, according to the researchers.
How did they do it: The new model embryos, bypassing the need for sperm or egg cells, were developed in the laboratory alongside normal mouse embryos. They reversed the same stages of development up to eight and a half days after fertilization, and developed beating hearts and other foundations of organs.
why does it matter: The findings could help scientists learn more about how human embryos develop and provide insights into diseases, as well as provide an alternative to animals for testing. Studying how mouse stem cells interact at this point in development could also provide insight into why human pregnancy fails during the early stages, and how to prevent this from happening.
