Sperm donors need limits, says a European fertility group

Ties van der Meer doesn’t know how many siblings he has. The 47-year-old was conceived at a private fertility clinic using sperm from an anonymous donor. He eventually tracked down one sibling, but he may have others he’ll never find.

Other donor-conceived people have found they have tens or even hundreds of them. “It does make you feel a bit mass-produced,” said one who discovered they had 25 half-siblings.

In response, a European fertility organization says we need international limits on the number of children a single donor can contribute to.

Find out what their proposal could achieve—and where it may fall short .

How will AI understand the real world?

LLMs have transformed what AI can do with language, but helping machines understand and operate within physical spaces presents a different challenge. In response, researchers are developing a new form of artificial intelligence: world models.

At a LinkedIn Live event tomorrow, MIT Technology Review will explore how this technology could shape the future of robotics and open one of AI’s next major frontiers. Join Will Douglas Heaven, our senior editor for AI, and Sam Sinha, founding AI researcher and head of world models at 1X Technologies, for the conversation on Tuesday, July 14.

Register here to attend the free session at 9:30 PDT, 12:30 PM EDT, and 5:30 PM BST.

One More Thing

Colombian military officials intercepted this 40-foot-long uncrewed fiberglass “narco sub” in the ocean just off Tayrona National Park. CARLOS PARRA RIOS

How uncrewed narco subs could transform the Colombian drug trade

On a bright April morning in 2025, a surveillance plane operated by the Colombian military spotted a 40-foot-long “narco sub” idling in the Caribbean Sea. The stealthy vessel, used by drug cartels to move cocaine north, could sail with its hull almost entirely underwater.

After seizing the boat, the coast guard noticed something unusual: there was no one on board. This was Colombia’s first confirmed uncrewed narco sub, operable by remote control, but also capable of a degree of autonomous travel.

Uncrewed subs could move more cocaine over longer distances, and they won’t put human smugglers at risk of capture. Find out how they may transform the drug trade .
