Even the tiniest of living things are capable of some amazing forms of locomotion, and some come with highly sophisticated sensor suites and manage to source their energy from the environment. Attempts to approach this sort of flexibility with robotics have taken two forms. One involves making tiny robots modeled on animal behavior . The other involves converting a living creature into a robot. So far, either approach has involved giving up a lot. You're either only implementing a few of life's features in the robot or shutting off most of life's features when taking over an insect.

But a team of researchers at Harvard has recognized that there are some behaviors that are so instinctual that it's possible to induce animals to act as if they were robotic. Or mostly robotic, at least—the fruit flies the researchers used would occasionally go their own way, despite strong inducements to stay with the program.

Smell the light

The first bit of behavior involved Drosophila 's response to moving visual stimuli. If placed in an area where the fly would see a visual pattern that rotates from left to right, the fly will turn to the right in an attempt to keep the pattern stable. This allowed a projector system to "steer" the flies as they walked across an enclosure (despite their names, fruit flies tend to spend a lot of their time walking). By rotating the pattern back and forth, the researchers could steer the flies between two locations in the enclosure with about 94 percent accuracy.

Google has unveiled a new AI processor, the seventh generation of its custom TPU architecture. The chip, known as Ironwood, was reportedly designed for the emerging needs of Google's most powerful Gemini models, like simulated reasoning, which Google prefers to call "thinking." The company claims this chip represents a major shift that will unlock more powerful agentic AI capabilities. Google calls this the "age of inference."

Whenever Google talks about the capabilities of a new Gemini version, it notes that the model's capabilities are tied not only to the code but to Google's infrastructure. Its custom AI hardware is a key element of accelerating inference and expanding context windows. With Ironwood, Google says it has its most scalable and powerful TPU yet, which will allow AI to act on behalf of a user to proactively gather data and generate outputs. This is what Google means when it talks about agentic AI.

Ironwood delivers higher throughput compared to previous Google Tensor Processing Units (TPUs), and Google really plans to pack these chips in. Ironwood is designed to operate in clusters of up to 9,216 liquid-cooled chips, which will communicate directly with each other through a newly enhanced Inter-Chip Interconnect (ICI).

A rare spot of good news today: For the second year in a row, US roads got a little safer. The National Highway Traffic Safety Administration published its early estimate of road deaths in 2024; 39,345 people lost their lives, which is a 3.8 percent decrease from the 40,901 deaths that occurred on US roads in 2023.

The problem started with the pandemic; although road traffic dried up, the death rate leapt by 20 percent .

There's no single cause, and studies have identified multiple contributing factors: empty roads designed to practically encourage speeding , little to no enforcement of traffic laws by the police, a general sense of fatalism in the face of public health restrictions that few Americans had ever contemplated in recent times, and car companies making big trucks and SUVs with high hoods, which are much more deadly to pedestrians and other vulnerable road users in a crash.

As President Donald Trump signed a slew of executive orders Tuesday aimed at keeping coal power alive in the United States, he repeatedly blamed his predecessor, Democrats, and environmental regulations for the industry’s dramatic contraction over the past two decades.

But across the country, state and local officials and electric grid operators have been confronting a factor in coal’s demise that is not easily addressed with the stroke of a pen: its cost.

For example, Maryland’s only remaining coal generating station, Talen Energy’s 1.3-gigawatt Brandon Shores plant, will be staying open beyond its previously planned June 1 shutdown, under a deal that regional grid operator PJM brokered earlier this year with the company, state officials, and the Sierra Club.

Are you a millennial parent who has made cycling your entire personality but have found it socially unacceptable to abandon your family for six hours on a Saturday? Or are you a bike-curious urban dweller who hasn’t owned a bicycle since middle school? Do you stare at the gridlock on your commute, longing for a bike-based alternative, but curse the errands you need to run on the way home?

I have a solution for you: invest in a cargo bike.

Cargo bikes aren't for everyone, but they're great if you enjoy biking and occasionally need to haul more than a bag or basket can carry (including kids and pets). In this guide, we'll give you some parameters for your search—and provide some good talking points to get a spouse on board.

Last week, Nintendo made waves across the game industry by announcing that Mario Kart World would sell for a suggested price of $80 in the US. That nominal price represents a new high-water mark both for Nintendo and for the game industry at large, which has generally reserved prices above $70 for fancy, trinket-laden collectors' editions or Digital Deluxe Editions that include all variety of downloadable bonuses.

When you adjust historical game prices for inflation, though, you find that asking $80 for a baseline game in 2025 is broadly in line with the prices big games were commanding 10 to 15 years ago. And given the faster-than-normal inflation rates of the last five years , even the $70 nominal game prices that set a new standard in 2020 don't have the same purchasing oomph they once did.

The data

To judge Mario Kart World 's $80 price against historical trends, we first needed to figure out how much games cost in the past. To do that, we built off of our similar 2020 analysis , which relied on scanned catalogs and retail advertising fliers for real examples of nominal console game pricing going back to the Atari era. For more recent years, we relied more on press reports and archived digital storefronts to show what prices new games were actually selling for at the time.

A leak of 190,000 chat messages traded among members of the Black Basta ransomware group shows that it’s a highly structured and mostly efficient organization staffed by personnel with expertise in various specialities, including exploit development, infrastructure optimization, social engineering, and more.

The trove of records was first posted to file-sharing site MEGA. The messages, which were sent from September 2023 to September 2024, were later posted to Telegram in February 2025 . ExploitWhispers, the online persona who took credit for the leak, also provided commentary and context for understanding the communications. The identity of the person or persons behind ExploitWhispers remains unknown. Last month’s leak coincided with the unexplained outage of the Black Basta site on the dark web, which has remained down ever since.

“We need to exploit as soon as possible”

Researchers from security firm Trustwave’s SpiderLabs pored through the messages, which were written in Russian, and published a brief blog summary and a more detailed review of the messages on Tuesday.

Coffee is one of the most popular beverages in the world, counting many scientists among its fans. Naturally those scientists are sometimes drawn to study their beloved beverage from various angles with an eye toward achieving the perfect cup.

While espresso has received the lion's share of such attention, physicists at the University of Pennsylvania have investigated the physics behind brewing so-called "pour-over" coffee, in which hot water is poured over coffee grounds in a filter within a funnel-shaped cone and allowed to percolate and drip into a cup below. The trick is to pour the water from as high as possible without letting the jet of water break up upon impact with the grounds, according to their new paper published in the journal Physics of Fluids.

In 2020, we reported on a mathematical model for brewing the perfect cup of espresso with minimal waste. Many variables can affect the quality of a steaming cup of espresso, including so-called "channeling" during the brewing process, in which the water doesn't seep uniformly through the grounds but branches off in various preferential paths instead. This significantly reduces the extraction yield (EY)—the fraction of coffee that dissolves into the final beverage—and thus the quality of the final brew. That, in turn, depends on controlling water flow and pressure as the liquid percolates through the coffee grounds.

Twitch has struck a deal with Elon Musk's X (formerly Twitter) to eject itself from a lawsuit over an ad boycott shortly following Musk's takeover of Twitter in October 2022.

In a court filing Monday, X lawyers provided no details on the deal but explained that "X and Twitch have entered into a memorandum of understanding resolving the action as to Twitch," so long as "certain conditions" are met by December 31.

Musk has called for "criminal prosecution" of anyone involved in the ad boycott. But while Twitch was one of about a dozen companies that X directly accused of conspiring to withhold billions in ad revenue from then-Twitter, it was not part of X's initial complaint. The livestreaming service was only added to the lawsuit after X amended its complaint in November to pull in more advertisers, and since then, Twitch has never responded to any of X's accusations. Instead, in its filing, X speaks for Twitch.
