In spring 2024, two days after undergoing complex cardiac surgery in the Midlands, a man in his mid-70s unexpectedly deteriorated and died.

The hospital referred the death to the coroner’s service, as is protocol when a cause is unknown, and clinical negligence barrister Anthony Searle was instructed by the man’s devastated family to represent them.

To try to get to the bottom of what had happened, Searle knew he would need to ask the surgeons some probing questions. So when the coroner declined his request for an independent expert report, Searle was frustrated.

BROOMFIELD, Colorado—One of NASA's oldest astronomy missions, the Neil Gehrels Swift Observatory, has been out of action for more than a month as scientists await the arrival of a pioneering robotic rescue mission.

The 21-year-old spacecraft is falling out of orbit, and NASA officials believe it's worth saving—for the right price. Swift is not a flagship astronomy mission like Hubble or Webb, so there's no talk of sending astronauts or spending hundreds of millions of dollars on a rescue expedition. Hubble was upgraded by five space shuttle missions, and billionaire and commercial astronaut Jared Isaacman—now NASA's administrator— proposed a privately funded mission to service Hubble in 2022, but the agency rejected the idea.

Swift may be a more suitable target for a first-of-a-kind commercial rescue mission. It has cost roughly $500 million (adjusted for inflation) to build, launch, and operate, but it is significantly less expensive than Hubble, so the consequences of a botched rescue would be far less severe. Last September, NASA awarded a company named Katalyst Space Technologies a $30 million contract to rapidly build and launch a commercial satellite to stabilize Swift's orbit and extend its mission.

The 1980s brought us so many terrific films, including director Russell Mulcahy's sword-and-sorcery fantasy action film Highlander , starring Christopher Lambert as an immortal Scotsman who must battle others like him to the death until just one remains. The film spawned two direct sequels and two TV series (one live action, one animated), and a planned reboot has been kicking around Hollywood since 2008. But the original still stands tall as the best of the bunch, 40 years later.

(Spoilers below because it's been 40 years.)

Screenwriter Gregory Widen was a college student at UCLA when he wrote the first draft of what would become Highlander for a screenwriting class. It was originally entitled Shadow Clan and partially inspired by Ridley Scott's 1977 film about two swordsmen engaged in a longstanding feud ( The Duelists ). Combine that with Widen's visits to Scotland and the Tower of London, with its impressive display of historical armor, and Widen had all he needed for his tale of dueling Immortals secretly living among us. He sold that first draft for $200,000—a princely sum for a college student—and a few revisions later, Highlander was ready for filming.

More than 13,000 feet below the surface of the Pacific Ocean, a more-than-70-ton machine trundled like a tank on its caterpillar tracks for a tenth of a mile—sucking up potato-sized nodules of rock packed with copper, manganese, cobalt, and nickel. It was 2022, and that pilot run of a subsea harvester by a Canadian business, The Metals Company, was pronounced a success.

The company is working to get a green light to deploy similar machines for commercial harvesting over an area of 65,000 square kilometers, to extract over 600 million metric tons of nodules.

There are riches on the ocean floor—round deposits made up of tightly packed layers of critical minerals that have long been out of reach. But not anymore. The pursuits of The Metals Company are among 31 initiatives by companies, governments and state-owned enterprises—including China, India, and the Republic of Nauru, a tiny island nation in the southwestern Pacific Ocean—to collect nodules for analysis and to test mining equipment.

On Monday, a paper announcing that all four DNA bases had been found on an asteroid sparked a lot of headlines. But many of the headlines omitted a key word needed to put the discovery in context: "again." The paper itself cited similar results dating back to 2011, and the ensuing years have seen various confirmations and more rigorous studies. The new work was less notable for showing that we had found these bases in Ryugu than for solving a previous mystery: earlier studies had failed to detect them there, despite their presence in many other asteroid samples.

Outside the headlines, though, the new work provides some interesting details, as it may answer an important question: how these bases got there in the first place. Understanding that better may be critical for getting a better picture of how the raw materials for life ended up on Earth in the first place.

Searching for bases

Let's start with a description of what the researchers found. Both DNA and RNA, the two nucleic acids used by life, share a similar structure. That includes the backbone, a chain that alternates between sugars and phosphates that are all chemically linked together. While the specific sugar differs between DNA and RNA, the chain itself varies only in length; otherwise, the backbone of every DNA or RNA molecule is identical.

Last summer, a group of officials from the Department of Energy gathered at the Idaho National Laboratory, a sprawling 890-square-mile complex in the eastern desert of Idaho where the US government built its first rudimentary nuclear power plant in 1951 and continues to test cutting-edge technology.

On the agenda that day: the future of nuclear energy in the Trump era. The meeting was convened by 31-year-old lawyer Seth Cohen. Just five years out of law school, Cohen brought no significant experience in nuclear law or policy; he had just entered government through Elon Musk’s Department of Government Efficiency team.

As Cohen led the group through a technical conversation about licensing nuclear reactor designs, he repeatedly downplayed health and safety concerns. When staff brought up the topic of radiation exposure from nuclear test sites, Cohen broke in.

On Friday, a jury in California determined that Elon Musk had misled investors in Twitter via public statements that depressed the price of the company's stock ahead of his ultimately successful purchase of it. Because it was a class action lawsuit, Musk is likely to be faced with paying out damages to a huge range of investors, payments that may ultimately reach billions of dollars.

In the lead up to Musk's ultimate purchase of the social media platform, he made a number of comments on the platform itself and while appearing as a guest on a podcast that raised questions about whether the sale would go through, largely focused on the prevalence of bot accounts on the platform. This depressed the price of the company's shares and raised fears that the deal wouldn't go through, causing some investors to sell shares at a depressed price during this period.

A number of those investors started a suit that was certified as a class action, claiming that the statements defrauded them, and that Musk did so intentionally as part of a larger scheme. The jury rejected the arguments about the larger scheme, but found Musk liable for the tweets.

There's a virus you may have never heard of before that is estimated to infect up to 90 percent of people and lurks quietly in your cells for life—but if it becomes activated, it will destroy your brain. If that's not startling enough, researchers reported this week that there may be a new way for this virus to activate—one that affects up to 10 percent of adults worldwide.

The virus is the human polyomavirus 2, commonly called either the JC virus or John Cunningham virus, named after the poor patient from whom it was first isolated in 1971. It shows up in the urine and stool of infected people and spreads via the fecal-oral route. Many people are thought to be infected early in life, and blood testing surveys have suggested that 50–90 percent of adults have been exposed at some point.

Researchers hypothesize that the initial site of infection is the tonsils, or perhaps the gastrointestinal tract. But wherever it happens, that initial infection is asymptomatic. At that point, a person is infected with what's called the archetype JC virus , which quietly sets up a persistent but utterly silent lifelong infection.

For the fourth time in a little more than a year, the US Space Force needs to send up a new satellite to replenish the military's GPS navigation network. And once again, the company the Pentagon is paying to launch it can't answer the call.

United Launch Alliance, a 50-50 joint venture between Boeing and Lockheed Martin, was supposed to launch the final satellite for the Space Force's GPS Block III program this month. Space Systems Command, responsible for buying spacecraft and rockets for the military, announced Friday it has transferred the launch to a Falcon 9 rocket from SpaceX, ULA's chief rival in the market for launching US government satellites.

This is only the latest example of the Space Force moving a GPS launch from ULA to SpaceX. The three most recent GPS satellites were also supposed to launch on ULA's Vulcan rocket. Beginning in 2024, the Space Force shifted them over to SpaceX. In exchange, military officials moved three future launches from SpaceX to ULA, including the launch of the GPS III SV10 satellite.
