Back in 2020, we reported that emulator developers were using a hole in the Xbox Store's app distribution system to get around Microsoft's longstanding ban on emulators running on Xbox consoles. This week, though, many of the emulators that were distributed through that workaround have stopped working, the apparent victims of a new crackdown by Microsoft.

Xbox emulator makers and users can't say they weren't warned. In the "Gaming and Xbox" section of Microsoft's official Store Policies, section 10.13.10 clearly states that "products that emulate a game system or game platform are not allowed on any device family."

Microsoft's enforcement of this clause has historically focused on removing emulators published as "private" UWP apps to the Xbox Store. Those apps could be distributed to whitelisted users via direct links accessed on the system's Edge browser, getting around the usual approval process for a public store listing.

Star Wars Celebration Day kicked off with the release of an extended teaser for Ahsoka, the latest interconnected series in the Star Wars franchise set to debut this summer on Disney+. Written by Dave Filoni, the series stars Rosario Dawson in the title role.

The Jedi Padawan of Anakin Skywalker, Ahsoka was first introduced as a supporting character in 2008's animated film Star Wars: The Clone Wars and the subsequent animated series. The character returned in the sequel series Star Wars Rebels (2014-2018) as a member of the Rebel Alliance, operating under the codename Fulcrum, and made numerous other cameo appearances in the extended Star Wars universe. Dawson's live-action version made her debut in The Mandalorian's second season. We last saw Ahsoka briefly in The Book of Boba Fett, when she passed on a gift of chain mail to Grogu after warning Mando/Din Djarin that his presence would be a distraction from Grogu's Jedi training. We all know how that turned out: Din and Grogu reunited and went on to share even more adventures in The Mandalorian S3, which will wrap later this month.

The official premise for Ahsoka is short and sweet: "Set after the fall of the Empire, Ahsoka follows the former Jedi knight Ahsoka Tano as she investigates an emerging threat to a vulnerable galaxy." In addition to Dawson, the cast includes Natasha Liu Bordizzo as Sabine Wren, a young Mandalorian warrior, graffiti artist, and former bounty hunter; Mary Elizabeth Winstead as Hera Syndulla, a former pilot for the Rebellion; Eman Esfandi as Ezra Bridger, a former con artist and thief who trained as a Jedi; and Ray Stevenson as Baylan.

In the past, Tesla CEO Elon Musk has repeatedly claimed that his company's cars are appreciating assets. But this week, Tesla dropped the prices of its cars—and not for the first time this year. As we reported on Monday, despite sales growing by 36 percent globally, the automaker missed its ambitious target and will need to grow even faster in the remaining months of the year to satisfy investors.

Perhaps these cuts will help. The biggest price decreases are for the Model S sedan and Model X SUV. All versions of these electric vehicles are now $5,000 cheaper than they were last week, following similar $5,000 price cuts a month ago and much larger price cuts in January that saw the Model S Plaid shed $21,000 from its MSRP.

Model 3 sedans are now $1,000 cheaper across the board, marking their third price cut in recent months. A rear-wheel-drive Model 3 now starts at $41,990—in January, this version cost $43,990; it then dropped another $500 in February. Tesla notes that the RWD Model 3 will also lose half of the IRS clean vehicle tax credit starting on April 18, although all-wheel drive Model 3s and all Model Ys will still be eligible for the full $7,500 credit.

Twitter users on Friday began noticing that they could not retweet or reply to tweets containing links to the Substack.com domain. This behavior seems to have started less than 48 hours after the popular newsletter platform announced a new product called Notes that will compete directly with Twitter.

For example, this tweet references my newsletter, understandingai.substack.com. When I try to retweet it, it gives me an error message saying, "Some actions on this tweet have been disabled by Twitter." If I try to reply to the same tweet, I get an error message saying, "Something went wrong, but don't fret—let's give it another shot." Even liking isn't allowed.

This tweet is identical, except that I linked to my custom domain, understandingai.org. I have no trouble liking, retweeting, or replying to it.

The early days of how an embryo develops are shrouded in mystery, because it pulls a kind of vanishing act. Once a sperm finds an egg, it begins a roughly weeklong journey to the uterus, becoming a tiny ball of cells along the way. When it reaches its destination, it attaches to the wall of the uterus, disappearing from view.

To shed light on the process, researchers are trying to create embryo-like structures derived from stem cells, rather than sperm and eggs, so they can observe early development in the lab. These three-dimensional balls of cells could offer clues to how diseases, birth defects, and miscarriages arise, without the practical and ethical concerns raised by using actual embryos. In the latest effort, researchers in China made these structures using stem cells from macaques and tried to establish pregnancies with them in female monkeys. The experiment is described in the journal Cell Stem Cell. Although other researchers have created “synthetic” embryos before, it’s the first time anyone has done it with monkeys—animals closely related to humans—and tried to get them to implant in the uterus.

There is evidence that ancient Egyptian soldiers would sever the right hands of foes and present them to the Pharaoh. That evidence comes in the form of tomb inscriptions of prominent warriors, as well as inscriptions and iconography on temple reliefs. Archaeologists have now discovered the first physical evidence of such a trophy-taking practice, according to a recent paper published in the journal Scientific Reports. The severed right hands of 12 individuals were excavated from pits within a courtyard of a 15th Dynasty palace in northeastern Egypt.

The 15th Dynasty (circa 1640-1530 BCE) rulers were known as Hyksos ("rulers of foreign lands"), although they did not control all of Egypt from their seat of power in the city of Avaris—the pharaohs of the 16th and 17th Dynasties ruled from Thebes during the same time period. Historians disagree about whether the Hyksos came to Egypt as invaders or gradually settled in the Nile delta before rising to power. But by the late 17th Dynasty, the Hyksos and the pharaohs were at war, leading to the former's defeat by Ahmose I, who founded the 18th Dynasty.

But the Hyksos nonetheless left their mark on Egyptian culture in the form of certain technological advances and customs, including the practice of presenting the severed right hands of defeated foes in a so-called "gold of honor" ceremony in exchange for a collar of golden beads. Per the authors, the Egyptians seem to have adopted the custom during Ahmose I's reign at the latest, based on a relief showing a pile of hands in his temple in Abydos. Tomb inscriptions and temple reliefs from the 18th to the 20th Dynasties "consistently depict hand counts on the battlefield following major battles," the authors wrote. However, there was no physical evidence of the custom beyond iconographic and literary sources—until now.
