When the discovery of fossilized footprints made in what’s now New Mexico was made public in 2021, it was a bombshell moment for archaeology, seemingly rewriting a chapter of the human story. Now new research is offering further evidence of their significance.

While they look like they could have been made yesterday, the footprints were pressed into mud 21,000 to 23,000 years ago, according to radiocarbon dating of the seeds of an aquatic plant that were preserved above and below the fossils.

This date dramatically pushed back the timeline of humans’ history in the Americas, the last landmass to be settled by prehistoric people. The 61 dated prints, which were discovered in the Tularosa Basin, near the edge of an ancient lake in White Sands National Park, were made at a time when many scientists think that massive ice sheets had sealed off human passage into North America, indicating that humans arrived in the region even earlier.

Competition in the burgeoning electric vehicle market is heating up. Green car enthusiasts are already salivating at the chance to test-drive the Nissan LEAF and the Chevrolet Volt when they hit dealerships late this year. Now, it seems an underdog has stepped out from the shadows to give these big hitters a real run for their money.

At this year’s Detroit Auto Show, Chinese automaker BYD announced plans to break into the North American auto market by selling their all-electric e6 in the United States by the end of the year.

While Chevy and Nissan don’t have much to worry about in the short-term — initial rollout is currently slated for the Southern California market only — BYD has some pretty lofty goals that could spell trouble over the next few years. Specifically, BYD (which stands for “Build Your Dreams”) plans on becoming no less than the world’s largest automaker by 2025.

Since the system is designed to help those who are losing their voices due to motor or cognitive impairment, the training is also flexible. If you can’t do a 15-minute training session, you can stop and start until you’ve made it through all the sentences. In addition, the training system is self-guided, so there’s no screen-tapping necessary.

While the system is not designed as a voice-over system, you can use Personal Vocie to save often-used phrases like “How are you?” “Thank you,” and “Where is the bathroom?”

Personal Voice will live under Settings/Accessibility on the iPhone, iPad, and Mac, and works with any of these devices running Apple silicon. For now, it only supports English.

This rival AI, named Claude, has one big advantage over ChatGPT: a much longer memory.
