"If you're going to make a car and use all that energy, it should be a good car," said Thomas Ingenlath, CEO of Polestar. Ingenlath was referring to the company's latest electric vehicle, a midsize SUV with striking coupe looks called the Polestar 4. While Ingenlath is on point from a sustainability perspective, it makes good business sense, too. The Polestar 4 needs to be a good car to stand out as it enters one of the most hotly contested segments of the market.

In fact, Polestar uses less energy to make its latest EV than anything else in its range—the company quotes a carbon footprint of 19.9 tonnes of CO₂ from cradle to gate. Like some other automakers, Polestar is using a monomaterial approach to the interior to make recycling easier, choosing the same base plastic for all the components in a particular piece of trim, for example.

The carpets are made from, variously, recycled fishing nets or plastic bottles. The vinyl seats use pine oil instead of the stuff extracted from the ground, and the knitted upholstery fabric—also recycled plastic bottles—was designed to leave no off-cuts.

Ultra-athlete Ross Edgley is no stranger to pushing his body to extremes. He once ran a marathon while pulling a one-ton car; ran a triathlon while carrying a 100-pound tree; and climbed a 65-foot rope over and over again until he'd climbed the equivalent of Mt. Everest—all for charity. In 2016, he set the world record for the world's longest staged sea swim around the coastline of Great Britain: 1780 miles over 157 days.

At one point during that swim, a basking shark appeared and swam alongside Edgley for a day and a half. That experience ignited his curiosity about sharks and eventually led to his new National Geographic documentary, Shark vs. Ross Edgley—part of four full weeks of 2024 SHARKFEST programming. Edgley matches his athletic prowess against four different species of shark. He tries to jump out of the water (polaris) like a great white shark; withstand the G forces produced by a hammerhead shark's fast, rapid turns; mimic the extreme fasting and feasting regimen of a migrating tiger shark; and match the swimming speed of a mako shark.

"I love this idea of having a goal and then reverse engineering and deconstructing it," Edgley told Ars. "[Sharks are] the ultimate ocean athletes. We just had this idea: what if you're crazy enough to try and follow in the footsteps of four amazing sharks? It's an impossible task. You're going to fail, you're going to be humbled. But in the process, we could use it as a sports/shark science experiment, almost like a Trojan horse to bring science and ocean conservation to a new audience."

In a vast stretch of the Sonoran Desert, between the towns of San Luis Río Colorado and Sonoyta in northern Mexico, sits a modest building of cement, galvanized sheet metal, and wood—the only stop along 125 miles of inhospitable landscape dominated by thorny ocotillo shrubs and towering saguaro cactuses up to 50 feet high. It’s a fonda—a small restaurant—called La Liebre del Desierto (The Desert Hare), and for more than 20 years, owner Elsa Ortiz Ramos has welcomed and nourished weary travelers taking a break from the adjacent highway that runs through the arid Pinacate and Grand Desierto de Altar Biosphere Reserve.

But the dedication and care of this petite woman go beyond her simple menu. Every two weeks, she pays out of pocket for a 5,000-gallon tank of water to distribute to a network of water troughs strategically placed in the area. By doing so, she relieves the thirst of bighorn sheep, ocelots, pronghorn, coyotes, deer, and even bats that have been deprived of access to their natural water sources.

“The crows come to the house and scream to warn us that there is no more water ... it’s our alarm,” says Ortiz Ramos in her distinct northern Mexico accent. Her words sound straight from an Aesop’s fable, but they take on stark realism in this spot. Covering large parts of Arizona, California, and the Mexican states of Baja California and Sonora, the Sonoran Desert—along with the Lut Desert in Iran—was cataloged in 2023 as having the hottest surface temperature on the planet, at 80.8° Celsius (177° Fahrenheit).

A remake of Riven: The Sequel to Myst launched this week, made by the original game's developers. It strikes a fascinating balance between re-creation and reinvention, and based on a couple of hours of playing it, it's a resounding success.

Myst was the classic most people remembered fondly from the early CD-ROM era, but for me, its sequel, Riven, was the highlight. After that, the sequels declined in quality. The sophomore effort was the apex.

It was certainly more ambitious than Myst. Instead of a handful of tightly packed theme park worlds, it offered a singular, cohesive one that felt lived in and steeped in history in a way that Myst couldn't quite match.
