Rapid advancements in robotics are changing the face of the world’s warehouses, as dangerous and physically taxing tasks are being reassigned en masse from humans to machines. Automation and digitization are nothing new in the logistics sector, or any sector heavily reliant on manual labor. Bosses prize automation because it can bring up to two- to four-fold gains in productivity. But workers can also benefit from the putative improvements in safety that come from shifting dangerous tasks onto non-human shoulders.

At least, that’s the story employers such as Amazon have—largely successfully—promoted to the public.

In a recent study, Brad N. Greenwood, Dean’s Distinguished Professor at the Costello College of Business at George Mason University, investigated this question: Does automation make warehouse jobs safer? His co-authors include Gordon Burtch of Boston University and Kiron Ravindran of IE University. Their findings, which appear in ILR Review, reveal that the answer depends on how safety is defined.

The researchers distinguish between two types of injuries: severe and non-severe. Severe injuries include broken bones, traumatic falls, and other incidents that cause employees to miss work. Non- include sprains, strains, and repetitive motion problems, often leading to reassignment or light-duty work, but not missing work.

The findings showed that robots do seem to reduce severe injuries. In robotic fulfillment centers (FC), tasks like heavy lifting and long walks are handled by machines, reducing workers’ exposure to physical hazards. The researchers found a meaningful drop in the number of severe injuries in these facilities.

However, the overall picture is not so clear. In the same robotic warehouses, the researchers observed a sharp increase in non-severe injuries, especially during high-demand periods such as Amazon Prime Day and the winter holidays. The robotic fulfillment centers experienced a 40% decrease in severe injuries but a 77% increase in non-severe injuries compared to traditional centers.

To better understand their results, the researchers also analyzed thousands of online posts from Amazon warehouse workers.

“There was an immediate and obvious discrepancy in opinion, based on whether their fulfillment center was roboticized or not,” says Greenwood.

Humans working alongside robots described their daily experience as “not physically exhausting” and “better than working at a legacy FC.” However, they also reported being expected to meet much higher performance metrics than their counterparts in non-automated FCs—amounting to a two-to-three-times higher “pick rate” in some cases. The faster pace of the human/robot dance was accompanied by a far more repetitive work routine that induced burnout in some workers, while causing others to “zone out.”

This dual reality—robots reducing some injuries while exacerbating others—has serious implications. For employers, simply introducing automation is not enough. Without careful job design, task rotation, and realistic performance goals, the shift to robotics can create new health and safety risks.

“Companies have bottom-line reasons to take this issue seriously. Beyond simple issues of liability, there is a cost to the firm of workers being unable to perform their duties,” says Greenwood.

Traditional safety metrics often focus on injuries that result in lost workdays. But as the nature of work changes, this approach may miss more subtle forms of harm. Chronic, repetitive injuries may not lead to time off, but they still decrease worker well-being and performance.

Looking ahead, Greenwood and his colleagues plan to explore how these trends play out over longer timeframes and in other industries. As robots become more common in fields like manufacturing, retail, and health care, similar patterns may emerge. The researchers hope their findings will help inform both corporate and public policy, ensuring that the future of work is not only more efficient but also humane.

“That isn’t to deny that warehouse robotics benefits workers,” Greenwood explains. “But we need to think more carefully about how to use them, and what that means for the humans they work with.”

Trump’s War on Iran Could Screw Over US Farmers

Trump’s War on Iran Could Screw Over US Farmers


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.

Google’s Pixel 10a May Not Be Exciting, but It’s Still an Unbeatable Value

Google’s Pixel 10a May Not Be Exciting, but It’s Still an Unbeatable Value


The screen is brighter now, reaching a peak brightness of 3,000 nits, and I haven’t had any trouble reading it in sunny conditions (though it hasn’t been as sunny as I’d like it to be these past few weeks). I appreciate the glass upgrade from Gorilla Glass 3 to Gorilla Glass 7i. It should be more protective, and anecdotally, I don’t see a single scratch on the Pixel 10a’s screen after two weeks of use. (I’d still snag a screen protector to be safe.)

Another notable upgrade is in charging speeds—30-watt wired charging and 10-watt wireless charging. I’ll admit I haven’t noticed the benefits of this yet, since I’m often recharging the phone overnight. You can get up to 50 percent in 30 minutes of charging with a compatible adapter, and that has lined up with my testing.

My biggest gripe? Google should have taken this opportunity to add its Pixelsnap wireless charging magnets to the back of this phone. That would help align the Pixel 10a even more with the Pixel 10 series and bring Qi2 wireless charging into a more affordable realm—actually raising the bar, which wouldn’t be a first for the A-series. After all, Apple did exactly that with the new iPhone 17e, adding MagSafe to the table. Or heck, at least make the Pixel 10a Qi2 Ready like Samsung’s smartphones, so people who use a magnetic case can take advantage of faster wireless charging speeds.

Battery life has been OK. With average use, the Pixel 10a comfortably lasts me a full day, but it still requires daily charging. With heavier use, like when I’m traveling, I’ve had to charge the phone in the afternoon a few times to make sure it didn’t die before I got into bed. This is a fairly big battery for its size, but I think there’s more Google could do to extend juice, akin to Motorola’s Moto G Power 2026.

The Colorful MacBook Neo Is Apple’s Cheapest Laptop Ever

The Colorful MacBook Neo Is Apple’s Cheapest Laptop Ever


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.
