**Here’s what you need to know about the cruise ship hantavirus outbreak**

Last week, eight passengers aboard a Dutch-flagged cruise ship contracted a type of hantavirus transmitted by rats. Three have since died. But health experts stress that this situation is nothing like the coronavirus outbreak in 2020.

The Andes virus is known to spread between people, and there are no specific antiviral treatments or vaccines. Yet transmission appears to require a specific form of contact that the cruise ship fostered.

Here’s what you need to know about the outbreak—and why experts believe it can be contained.

**Musk v. Altman week 2: OpenAI fires back, and Shivon Zilis reveals that Musk tried to poach Sam Altman**

In the second week of the landmark trial between Elon Musk and OpenAI, Musk’s motivations for bringing the suit came under intense scrutiny.

OpenAI president Greg Brockman testified that Musk had pushed for the company to create a for-profit entity, while Shivon Zilis, a former board member, revealed that the Tesla tycoon had sought to lure Sam Altman to a new AI venture.

The courtroom also heard about Brockman’s private journals, Musk’s abandoned plans for a rival AI lab, and the moment he stormed out of a pivotal meeting carrying a painting of a Tesla.

Here’s what happened in the second week of the trial—and what’s coming next.

**How LLMs could supercharge mass surveillance in the US: 10 Things That Matter in AI Right Now**

There are pieces of your life scattered all over the internet, and some of them are for sale. Data brokers collect web searches, financial records, and location data from millions of people and sell them to various clients, including the US government.

While gathering that data has become easier in the smartphone era, making use of it at scale has remained difficult. But researchers are beginning to show that LLM agents can connect anonymized data to real people quickly, cheaply, and at a massive scale.

Find out why privacy experts fear AI could remove the friction that has long protected the public from mass surveillance.

#### Inside NASA’s bid to make spacecraft as small as possible

As NASA’s InSight lander descended to Mars in November 2018, two tiny spacecraft tracked its progress. InSight had touched down, they reported, and survived its treacherous journey.

The mission offered a pathway to cheaper space exploration, with small, low-cost probes launching far more often than multibillion-dollar flagship missions. But there’s a catch: miniaturization can only go so far before it collides with the hard limits of physics.
