Global oil and gas prices have skyrocketed following the US attack on Iran last weekend. But another key global supply chain is also at risk, one that may directly impact American farmers who have already been squeezed for months by tariff wars. The conflict in the Middle East is choking global supplies of fertilizer right before the crucial spring planting season.

“This literally could not be happening at a worse time,” says Josh Linville, the vice president of fertilizer at financial services company StoneX.

The global fertilizer market focuses on three main macronutrients: phosphates, nitrogen, and potash. All of them are produced in different ways, with different countries leading in exports. Farmers consider a variety of factors, including crop type and soil conditions, when deciding which of these types of fertilizer to apply to their fields.

Potash and phosphates are both mined from different kinds of natural deposits; nitrogen fertilizers, by contrast, are produced with natural gas. QatarLNG, a subsidiary of Qatar Energy, a state-run oil and gas company, said on Monday that it would halt production following drone strikes on some of its facilities. This effectively took nearly a fifth of the world’s natural gas supply offline, causing gas prices in Europe to spike.

That shutdown puts supplies of urea, a popular type of nitrogen fertilizer, particularly at risk. On Tuesday, Qatar Energy said that it would also stop production of downstream products, including urea. Qatar was the second-largest exporter of urea in 2024. (Iran was the third-largest; it’s also a key exporter of ammonia, another type of nitrogen fertilizer.) Prices on urea sold in the US out of New Orleans, a key commodity port, were up nearly 15 percent on Monday compared to prices last week, according to data provided by Linville to WIRED. The blockage of the Strait of Hormuz is also preventing other countries in the region from exporting nitrogen products.

“When we look at ammonia, we’re looking at almost 30 percent of global production being either involved or at risk in this conflict,” says Veronica Nigh, a senior economist at the Fertilizer Institute, a US-based industry advocacy organization. “It gets worse when we think about urea. Urea is almost 50 percent.”

Other types of fertilizer are also at risk. Saudi Arabia, Nigh says, supplies about 40 percent of all US phosphate imports; taking them out of the equation for more than a few days could create “a really challenging situation” for the US. Other countries in the region, including Jordan, Egypt, and Israel, also play a big role in these markets.

“We are already hearing reports that some of those Persian Gulf manufacturers are shutting down production, because they’re saying, ‘I have a finite amount of storage for my supply,’” Linville says. “‘Once I reach the top of it, I can’t do anything else. So I’m going to shut down my production in order to make sure I don’t go over above that.’”

Conflict in the strait has intensified in the early part of this week, as the Islamic Revolutionary Guard Corps have reportedly threatened any ship passing through the strait. Traffic has slowed to a crawl. The Trump administration announced initiatives on Tuesday meant to protect oil tankers traveling through the strait, including providing a naval escort. Even if those initiatives succeed—which the shipping industry has expressed doubt about—much of the initial energy will probably go toward shepherding oil and gas assets out of the region.

“Fertilizer is not going to be the most valuable thing that’s gonna transit the strait,” says Nigh.

After a week of product announcements—starting with the iPhone 17e, a refreshed iPad Air, and more powerful MacBook Pro models—Apple has unveiled a new category in its laptop lineup for the first time in a while: the “MacBook Neo.”

Positioned below the MacBook Air as an entry-level machine, this new MacBook is the most affordable laptop the company has ever made, with a starting price of $599. While it’s been possible to buy a new MacBook Air at lower prices—like the 2020 M1 MacBook Air Apple sold for several years for $699 exclusively through Walmart—this is officially the cheapest MacBook out the gate.

Aside from the price, its approach to color also makes it unique among the other MacBooks in Apple’s lineup. You have several color options, including Silver, Indigo, Blush, and Citrus. The colors harken back a bit to the iBook G3 of yesteryear and are akin to the current iMac design. In person, the colors aren’t a bright and bold as expected, still exhibiting a more subtle hue. Apple says the aluminum device weighs 2.7 pounds, which is the same as the 13-inch MacBook Air. We’re still waiting on official measurements on the thickness.

Despite its price, Apple doesn’t appear to be cutting corners on the quality of the screen. With a resolution of 2408 by 1506 and up to 500 nits of brightness, Apple boasts that it is “both brighter and higher in resolution than most PC laptops in this price range.” The display doesn’t use a notch for the webcam like the MacBook Air or MacBook Pro. There’s a 1080p camera, a Touch ID sensor, and side-firing speakers with Dolby Atmos. Unfortunately, the Touch ID sensor is only available on the $699 model, which comes with 512 GB of storage.

The MacBook Neo does make plenty of other concessions to hit its aggressive price though. It’s powered by the A18 Pro chip—the same processor inside the iPhone 16 Pro and 16 Pro Max. Yup—you read that right. iPads have used Mac chips for years, but now a MacBook is using an iPhone chip. Still, this processor should deliver more power than the original M1 chip in the MacBook Air. Apple claims the chip gives the MacBook Neo up to 16 hours of battery life. That’s less than the MacBook Air or MacBook Pro. Apple also says the chip is up to 50 percent faster in daily tasks like web browsing than “the bestselling PC with the latest chipping Intel Core Ultra 5.” According to the liner notes, this was based on a Speedometer test, a popular browser-based benchmark.

Other compromises to the device are the use of a mechanical multi-touch trackpad (rather than one that uses haptic feedback), a non-backlit keyboard, and the more limited port selection. The use of the iPhone chip means this MacBook only supports one external monitor through one if its two USB-C ports. Either port can be used for charging. There’s also a headphone jack, located in an odd position next to the side-firing speakers near the front of the device. While technically this is the same amount of USB-C ports as the MacBook Air, it’s missing the magnetic MagSafe 3 charging port, which frees up one of the USB-C ports.

Initially, Gorham used his brain-computer interface for single clicks, Oxley says. Then he moved on to multi-clicks and eventually sliding control, which is akin to turning up a volume knob. Now he can move a computer cursor, an example of 2D control—horizontal and vertical movements within a two-dimensional plane.

Over the years, Gorham has gotten to try out different devices using his implant. Zafar Faraz, a field clinical engineer for Synchron, says Gorham directly contributed to the development of Switch Control, a new accessibility feature Apple announced last year that allows brain-computer interface users the ability to control iPhones, iPads, and the Vision Pro with their thoughts.

In a video demonstration shown at an Nvidia conference last year in San Jose, California, Gorham demonstrates using his implant to play music from a smart speaker, turn on a fan, adjust his lights, activate an automatic pet feeder, and run a robotic vacuum in his home in Melbourne, Australia.

“Rodney has been pushing the boundaries of what is possible,” Faraz says.

As a field clinical engineer, Faraz visits Gorham in his home twice a week to lead sessions on his brain-computer interface. It’s Faraz’s job to monitor the performance of the device, troubleshoot problems, and also learn the range of things that Gorham can and can’t do with it. Synchron relies on this data to improve the reliability and user-friendliness of its system.

In the years he’s been working with Gorham, the two have done a lot of experimenting to see what’s possible with the implant. Once, Faraz says, he had Gorham using two iPads side by side, switching between playing a game on one and listening to music on the other. Another time, Gorham played a computer game in which he had to grab blocks on a shelf. The game was tied to an actual robotic arm at the University of Melbourne, about six miles from Gorham’s home, that remotely moved real blocks in a lab.

Gorham, who was an IBM software salesman before he was diagnosed with ALS in 2016, has relished being such a key part of the development of the technology, his wife Caroline says.

“It fits Rodney’s set of life skills,” she says. “He spent 30 years in IT, talking to customers, finding out what they needed from their software, and then going back to the techos to actually develop what the customer needed. Now it’s sort of flipped around the other way.” After a session with Faraz, Gorham will often be smiling ear to ear.

Through field visits, the Synchron team realized it needed to change the setup of its system. Currently, a wire cable with a paddle on one end needs to sit on top of the user’s chest. The paddle collects the brain signals that are beamed through the chest and transmits them via the wire to an external unit that translates those signals into commands. In its second generation system, Synchron is removing that wire.

“If you have a wearable component where there’s a delicate communication layer, we learned that that’s a problem,” Oxley says. “With a paralyzed population, you have to depend on someone to come and modify the wearable components and make sure the link is working. That was a huge learning piece for us.”
