Whales use complex communication systems we still don’t understand, a trope exploited in sci-fi shows like Apple TV’s Extrapolations. That show featured a humpback whale (voiced by Meryl Streep) discussing Mahler’s symphonies with a human researcher via some AI-powered inter-species translation app developed in 2046.

We’re a long way from that future. But a team of MIT researchers has now analyzed a database of Caribbean sperm whales’ calls and has found there really is a contextual and combinatorial structure in there. But does it mean whales have a human-like language and we can just wait until Chat GPT 8.0 to figure out how to translate from English to Sperm-Whaleish? Not really.

“Sperm whales communicate using clicks. These clicks occur in short packets we call codas that typically last less than two seconds, containing three to 40 clicks,” said Pratyusha Sharma, a researcher at the MIT Computer Science and Artificial Intelligence Laboratory and the lead author of the study. Her team argues that codas are analogues of words in human language and are further organized in coda sequences that are analogues of sentences. “Sperm whales are not born with this communication system; it's acquired and changes over the course of time,” Sharma said.

General Motors appears to have solved the problem that was holding back the production of its Ultium-based electric vehicles. These are now rolling out of factories—you can expect to read about the new Silverado EV tomorrow and the (allegedly affordable) Equinox EV next week, to name but two. We got a first-blush drive of the Blazer this past winter before GM had to put a stop on sales due to some… glitches. Now, with the vehicle back on sale and the software debugged, it's time to see if the fixes helped.

In reintroducing the Blazer EV and returning it to market, Chevy has also lowered the price pretty significantly, by an average of about $6,000 per model. The LT AWD now starts at $48,800, and there's a $7,500 incentive for customers who aren't eligible for the IRS clean vehicle tax credit. The RS AWD, which we tested, has an MSRP of $53,200, but with the delivery charge and GM's cash on the hood, it came in at $47,095. Both have a 85 kWh battery good for 279 miles (449 km) max range per charge. The longer-range, bigger-battery 102 kWh RS RWD boasts a more impressive 324 miles ( 521 km) per charge and works out to $48,670.

These are pretty competitive prices when you consider the mid-sized EV SUV segment. An obvious comparison: The Ioniq 5 SE AWD costs $49,350, cannot qualify for the federal tax credit (unless leased), and its range runs shy of the Chevy Blazer RS AWD, too, at 260 miles (418 km) versus the Chevy's 279.
