For the first time in four centuries, it’s good to be a beaver. Long persecuted for their pelts and reviled as pests, the dam-building rodents are today hailed by scientists as ecological saviors. Their ponds and wetlands store water in the face of drought, filter out pollutants, furnish habitat for endangered species, and fight wildfires. In California, Castor canadensis is so prized that the state recently committed millions to its restoration.

While beavers’ benefits are indisputable, however, our knowledge remains riddled with gaps. We don’t know how many are out there, or which direction their populations are trending, or which watersheds most desperately need a beaver infusion. Few states have systematically surveyed them; moreover, many beaver ponds are tucked into remote streams far from human settlements, where they’re near-impossible to count. “There’s so much we don’t understand about beavers, in part because we don’t have a baseline of where they are,” says Emily Fairfax, a beaver researcher at the University of Minnesota.

CAPE TOWN, South Africa—A weathered, green building stands at the edge of the cozy suburban Table View neighborhood in Cape Town, just a few blocks down from a Burger King and a community library. Upon stepping inside, visitors’ feet squelch on a mat submerged in antibacterial liquid—one of the first signs this isn’t just another shop on the street.

A few steps further down the main hallway, a cacophony of discordant brays and honks fill the air. A couple more strides reveal the source of these guttarall calls: African penguins.

Welcome to the nonprofit Southern African Foundation for the Conservation Of Coastal Birds’ hatchery and nursery, where hundreds of these birds are hand-reared after being injured or abandoned in the wild.

The mince pies have been eaten, the crackers have been cracked, and the days are starting to get longer. That means it's time to look back on the best vehicles we tested in 2023. It has been a good year for electric vehicles, which accounted for almost one in ten new vehicles sold in the US this year. We've also driven some rather good hybrids, as well as a pair of sports cars that reminded us that there's still room for enthusiast cars. Read on to find out which cars made the cut.

1. Polestar 2

In addition to claiming the top spot in 2023, Polestar might also win a prize for the most significant reengineering job for a midlife refresh. Normally, an automaker might restyle the bumpers or change the headlights and tweak the interior when it gives a model its spruce-up after a few years on sale. Not Polestar—it mostly left the cosmetics alone but moved the electric motor in the single-motor Polestar 2 from under the hood, where it drove the front wheels, to the rear, where it now drives the rear wheels.

Combined with a bit of a bump in power (ok, 29 percent more power and 48 percent more torque), the result is a real driver's car, with better steering and handling than the front-wheel drive Polestar 2 it replaces. There's more standard equipment than before, and it's more efficient, too. Only about 30 percent of US Polestar customers have picked the single-motor model in the past, but they're missing out. The twin-motor car might be faster, but it's less engaging to drive, has less range, and costs a whole bunch more.

Warning: Although we’ve done our best to avoid spoiling anything major, please note this list does include a few specific references to several of the listed shows that some might consider spoiler-y. The segment for The Great contains major reveals, so skip it if you haven't watched the latest season. (We'll give you a heads-up when we get there.)

Everything was coming up mystery in 2023, judging by our picks for Ars Technica's annual list of the best TV shows of the year. There's just something about the basic framework that seems to lend itself to television. Showrunners and studios have clearly concluded that genre mashups with a mystery at the center is a reliable winning formula, whether it's combined with science fiction (Silo, Bodies, Pluto), horror (Fall of the House of Usher), or comedy (Only Murders in the Building, The Afterparty). And there's clearly still plenty of room in the market for the classic police procedural (Dark Winds, Poker Face, Justified: City Primeval). Even many shows we loved that were not overt nods to the genre still had some kind of mystery at their core (Yellowjackets, Mrs. Davis), so one could argue it's almost a universal narrative framework.

Streaming platforms continue to lead, with Netflix, Apple TV+, and FX/Hulu dominating this year's list. But there are signs that the never-ending feast of new fare we've enjoyed for several years now might be leveling off a bit, as the Hollywood strikes took their toll and the inevitable reshuffling and consolidation continues. That would be great news for budgets strained by subscribing to multiple platforms, less so for those who have savored the explosion of sheer creativity during what might be remembered as a Golden Age of narrative storytelling on TV.
