Microsoft is rolling out a new face for its AI, and its name is Mico. The company announced the new, animated blob-like avatar for Copilot’s voice mode yesterday as part of a “human-centered” rebranding of Microsoft’s Copilot AI efforts.

Mico is part of a Microsoft program dedicated to the idea that “technology should work in service of people,” Microsoft wrote. The company insists this effort is “not [about] chasing engagement or optimizing for screen time. We’re building AI that gets you back to your life. That deepens human connection.”

Mico has drawn instant and obvious comparisons to Clippy , the animated paperclip that popped up to offer help with Microsoft Office starting in the ’90s . Microsoft has leaned into this comparison with an Easter egg that can transform Mico into an animated Clippy .

Electric vehicle startup Rivian announced on Thursday that it has settled a lawsuit with some of its investors. The company continues to deny allegations of making “materially untrue” statements during its inial public offering but says it agreed to pay $250 million to clear itself of distractions as it focuses on building its next EV, the mass-market R2 , which is due next year.

Rivian was first sued by a shareholder in 2022 over claims that the startup knew it would cost far more for it to build each R1T electric truck and R1S electric SUV than the advertised $67,500 and $70,000 prices, respectively. A big surprise price increase would tarnish the nascent automaker’s reputation, the lawsuit claimed, and could lead to many of the almost 56,000 pre-orders being canceled.

Just a few months after its November 2021 IPO, the company had indeed issued a hefty price hike : $79,500 for the R1T and $84,500 for the R1S SUV. After an outcry, the company said it would honor the original price for its existing preorders. By that point, though, the damage was done, and more than a third of the company’s value was erased within a few days, the lawsuit alleged.

There are three species of bats that eat birds. We know that because we have found feathers and other avian remains in their feces. What we didn’t know was how exactly they hunt birds, which are quite a bit heavier, faster, and stronger than the insects bats usually dine on.

To find out, Elena Tena, a biologist at Doñana Biological Station in Seville, Spain, and her colleagues attached ultra-light sensors to Nyctalus Iasiopterus , the largest bats in Europe. What they found was jaw-droppingly brutal.

Inconspicuous interceptors

Nyctalus Iasiopterus , otherwise known as greater noctule bats, have a wingspan of about 45 centimeters. They have reddish-brown or chestnut fur with a slightly paler underside, and usually weigh around 40 to 60 grams. Despite that minimal weight, they are the largest of the three bat species known to eat birds, so the key challenge in getting a glimpse into the way they hunt was finding sensors light enough to not impede the bats’ flight.

In 1812, Napoleon Bonaparte led a disastrous military campaign into Moscow. The death toll was devastating: Out of some 615,000 men, only about 110,000 survivors returned. (Napoleon abandoned his army in early December to return home on a sled.) Roughly 100,000 of the casualties died in battle, while as many as 300,000 perished from a combination of the bitter cold of Russia’s notoriously harsh winter, starvation, and disease.

Scholars have debated precisely what kinds of diseases ravaged Napoleon’s troops. New DNA analysis of some soldiers’ remains has revealed the presence of two pathogens in particular, according to a new paper published in the journal Current Biology. The first is Salmonella enterica , which causes paratyphoid fever ; the second is Borrelia recurrentis , which is transmitted by body lice and causes relapsing fever . (A preprint of the paper appeared on bioaRxiv in July.)

“It’s very exciting to use a technology we have today to detect and diagnose something that was buried for 200 years,” said co-author Nicolás Rascovan of the Institut Pasteur. “Accessing the genomic data of the pathogens that circulated in historical populations helps us to understand how infectious diseases evolved, spread, and disappeared over time and to identify the social or environmental contexts that played a part in these developments. This information provides us with valuable insights to better understand and tackle infectious diseases today.”

Over the years, racing sims have come a long way . Gaming PCs and consoles have become more powerful, physics and tire models have become more accurate, and after COVID, it seems like nearly everyone has a sim rig setup at home. Sim racing has even become an accepted route into the world of real-life motorsport (not to be confused with the Indy Racing League).

But what if you aren't looking to become the next Max Verstappen? What if you miss the more carefree days of old, where the fidelity wasn't quite so high, nor were the stakes? Rally Arcade Classics is worth a look.

Developed by NET2KGAMES, you might think of RAC as a spiritual successor to legendary titles like Sega Rally and Colin McRae Rally. Forget about the Nürburgring or even street circuits laid out in famous cities you might have visited; instead, this game is about point-to-point racing against the clock—mostly—across landscapes that long-time World Rally Championship fans will remember.

Apple's "Pro" iPhones usually look and feel a lot like the regular ones, just with some added features stacked on top. They've historically had better screens and more flexible cameras, and there has always been a Max option for people who really wanted to blur the lines between a big phone and a small tablet (Apple's commitment to the cheaper "iPhone Plus" idea has been less steadfast). But the qualitative experience of holding and using one wasn't all that different compared to the basic aluminum iPhone.

This year's iPhone 17 Pro looks and feels like more of a departure from the basic iPhone, thanks to a new design that prioritizes function over form. It's as though Apple anticipated the main complaints about the iPhone Air —why would I want a phone with worse battery and fewer cameras, why don't they just make the phone thicker so they can fit in more things —and made a version of the iPhone that they could point to and say, "We already make that phone—it's that one over there."

Because the regular iPhone 17 is so good, and because it uses the same 6.3-inch OLED ProMotion screen, I think the iPhone 17 Pro is playing to a narrower audience than usual this year. But Apple's changes and additions are also tailor-made to serve that audience. In other words, fewer people even need to consider the iPhone Pro this time around, but there's a lot to like here for actual "pros" and people who demand a lot from their phones.

Fermenting milk to make yogurt, cheeses, or kefir is an ancient practice, and different cultures have their own traditional methods, often preserved in oral histories. The forests of Bulgaria and Turkey have an abundance of red wood ants, for instance, so a time-honored Bulgarian yogurt-making practice involves dropping a few live ants (or crushed-up ant eggs) into the milk to jump-start fermentation. Scientists have now figured out why the ants are so effective in making edible yogurt, according to a paper published in the journal iScience. The authors even collaborated with chefs to create modern recipes using ant yogurt.

“Today’s yogurts are typically made with just two bacterial strains,” said co-author Leonie Jahn from the Technical University of Denmark. “If you look at traditional yogurt, you have much bigger biodiversity, varying based on location, households, and season. That brings more flavors, textures, and personality.”

If you want to study traditional culinary methods, it helps to go where those traditions emerged, since the locals likely still retain memories and oral histories of said culinary methods—in this case, Nova Mahala, Bulgaria, where co-author Sevgi Mutlu Sirakova's family still lives. To recreate the region's ant yogurt, the team followed instructions from Sirakova's uncle. They used fresh raw cow milk, warmed until scalding, "such that it could 'bite your pinkie finger,'" per the authors. Four live red wood ants were then collected from a local colony and added to the milk.

The largest electric utility in Illinois is rolling out a program for a vehicle-to-grid (V2G) electric school bus-charging pilot with three Chicagoland school districts, testing the functionality of bidirectional chargers that could make energy cheaper for customers and reduce grid load.

The Commonwealth Edison Co. (ComEd) announced in September that it would begin the testing phase of its novel V2G electric school bus charging pilot, the first of its kind in northern Illinois, coinciding with the beginning of the school year.

The utility began testing with the River Trails, Troy, and Wauconda school districts—which have all had electric buses for more than two years—in northern Illinois. It is currently collecting data from bidirectional chargers, EV chargers that flow energy both ways. Its testing will determine how the chargers and buses can best transfer energy when parked and plugged into the grid.

Welcome to Edition 8.13 of the Rocket Report! It's difficult for me to believe, but we have now entered the fourth quarter of the year. Accordingly, there are three months left in 2025, with a lot of launch action still to come. The remainder of the year will be headlined by Blue Origin's New Glenn rocket making its second flight (and landing attempt), and SpaceX's Starship making its final test flight of the year. There is also the slim possibility that Rocket Lab's Neutron vehicle will make its debut this year, but it will almost certainly slip into 2026.

As always, we welcome reader submissions , and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

An Alpha rocket blows up on the pad . The booster stage for Firefly Aerospace's next Alpha rocket was destroyed Monday in a fiery accident on the company's vertical test stand in Central Texas, Ars reports . Firefly released a statement confirming the rocket "experienced an event that resulted in a loss of the stage." The company confirmed all personnel were safe and said ground teams followed "proper safety protocols." Imagery posted on social media platforms showed a fireball engulfing the test stand and a column of black smoke rising into the sky over Firefly's facility roughly 40 miles north of Austin.
