Xiaomi, a Chinese maker of consumer electronics perhaps best known for taking plenty of inspiration from Apple, is getting into the automotive industry. Earlier today in Beijing, Xaiomi CEO Lei Jun debuted the Speed Ultra 7, a luxury electric vehicle that's squarely aimed at the spot in the market currently served by the Porsche Taycan and Tesla Model S sedans.

Xiaomi wanted to branch out from smartphones and tablets to EVs—that wasn't exactly news, as the company announced its plans about three years ago. Lei has big ambitions though; he wants Xiaomi to be a top-five automaker within the next two decades.

Making a car isn't that hard, Lei told the audience. "If you want to build a car, 300 or 400 people and a bit over a billion, and you find a benchmark car and you just need do reverse-engineering and you can do it," Lei said, then acknowledged that "to build a good car it is still very very difficult."

Spectacular scenery, from lush rainforests to towering mountain ranges, dots the surface of our planet. But some of Earth’s most iconic landmarks––ones that may harbor clues to the origin of life on Earth and possibly elsewhere––lay hidden at the bottom of the ocean. Scientists recently found one such treasure in Ecuadorian waters: a submerged mini Yellowstone called Sendero del Cangrejo.

This hazy alien realm simmers in the deep sea in an area called the Western Galápagos Spreading Center––an underwater mountain range where tectonic plates are slowly moving away from each other. Magma wells up from Earth’s mantle here to create new oceanic crust in a process that created the Galápagos Islands and smaller underwater features, like hydrothermal vents. These vents, which pump heated, mineral-rich water into the ocean in billowing plumes, may offer clues to the origin of life on Earth. Studying Earth’s hydrothermal vents could also offer a gateway to finding life, or at least its building blocks, on other worlds.

The newly discovered Sendero del Cangrejo contains a chain of hydrothermal vents that spans nearly two football fields. It hosts hot springs and geyser chimneys that support an array of creatures, from giant, spaghetti-like tube worms to alabaster Galatheid crabs.

Apple's AirTags are meant to help you effortlessly find your keys or track your luggage. But the same features that make them easy to deploy and inconspicuous in your daily life have also allowed them to be abused as a sinister tracking tool that domestic abusers and criminals can use to stalk their targets.

Over the past year, Apple has taken protective steps to notify iPhone and Android users if an AirTag is in their vicinity for a significant amount of time without the presence of its owner's iPhone, which could indicate that an AirTag has been planted to secretly track their location. Apple hasn't said exactly how long this time interval is, but to create the much-needed alert system, Apple made some crucial changes to the location privacy design the company originally developed a few years ago for its “Find My” device tracking feature. Researchers from Johns Hopkins University and the University of California, San Diego, say, though, that they've developed a cryptographic scheme to bridge the gap—prioritizing detection of potentially malicious AirTags while also preserving maximum privacy for AirTag users.
