HHS Winds Down mRNA Vaccine Development Under BARDA

WASHINGTON, D.C. — The U.S. Department of Health and Human Services (HHS) today announced the beginning of a coordinated wind-down of its mRNA vaccine development activities under the Biomedical Advanced Research and Development Authority (BARDA), including the cancellation and de-scoping of various contracts and solicitations. The decision follows a comprehensive review of mRNA-related investments initiated during the COVID-19 public health emergency. “We reviewed the science, listened to the

Delta denies using AI to set personalized ticket prices

What just happened? Delta Air Lines has categorically denied using artificial intelligence to set ticket prices based on individual customer data, responding to concerns raised by several members of the US Senate. The airline issued its statement following criticism from lawmakers who alleged that Delta was exploring advanced pricing models designed to tailor fares to the maximum amount each customer might be willing to pay – a practice sometimes referred to as surveillance pricing. The controv

Why Whole Milk Is Making a Comeback, According to Dietitians

In the 1990s, Got Milk? ads became popular because of a marketing campaign created by the California Milk Processor Board, encouraging people to drink more cow's milk through celebrity-packed ads and commercials. The interest eventually dwindled, and soon after, plant-based milks started to gain popularity. Since the 2000s, every version of plant-based milks you can imagine, ranging from soy, oat, almond, pistachio, macadamia, pea -- you name it, probably exists in your supermarket aisle. Now it

The many JavaScript runtimes of the last decade

July 27, 2025 The many, many, many JavaScript runtimes of the last decade This last decade has seen an inundation of new JavaScript runtimes (and engines in equal measure), enabling us to run JavaScript in all manner of contexts with precise fitness for task. Through these, we've seen the language spread to the Cloud, the edge, Smart TVs, mobile devices, and even microcontrollers. In this article, we'll explore what's driving this diversity, and why no one runtime or engine suffices for all p

Delta’s AI spying to “jack up” prices must be banned, lawmakers say

One week after Delta announced it is expanding a test using artificial intelligence to charge different prices based on customers' personal data—which critics fear could end cheap flights forever—Democratic lawmakers have moved to ban what they consider predatory surveillance pricing. In a press release, Reps. Greg Casar (D-Texas) and Rashida Tlaib (D-Mich.) announced the Stop AI Price Gouging and Wage Fixing Act. The law directly bans companies from using "surveillance-based" price or wage set

Rocket Report: Channeling the future at Wallops; SpaceX recovers rocket wreckage

Welcome to Edition 8.04 of the Rocket Report! The Pentagon's Golden Dome missile defense shield will be a lot of things. Along with new sensors, command and control systems, and satellites, Golden Dome will require a lot of rockets. The pieces of the Golden Dome architecture operating in orbit will ride to space on commercial launch vehicles. And Golden Dome's space-based interceptors will essentially be designed as flying fuel tanks with rocket engines. This shouldn't be overlooked, and that's

Proton’s new privacy-first AI assistant encrypts all chats, keeps no logs

Privacy-focused productivity tools maker Proton on Wednesday released its AI assistant, called Lumo, which it says prioritizes protecting user data. The company says the chatbot keeps no logs of your conversations, has end-to-end encryption for storing chats, and offers a ghost mode for conversations that disappear as soon as you close the window. Available via a web client, as well as Android and iOS apps, Lumo doesn’t require you to have an account to use the chatbot and ask questions. You c

Spanish police arrest five over $542M crypto investment scheme

Spanish law enforcement arrested five people suspected of running an international cryptocurrency investment fraud scheme that laundered more than €460 million ($542 million) from over 5,000 victims worldwide, according to a statement from Europol. The suspects, based in Madrid and the Canary Islands, allegedly operated a global network of accomplices who collected money through cash deposits, wire transfers and cryptocurrency transactions. According to Spain’s Guardia Civil, the criminal ring

Log by time, not by count

Log by Time, not by Count July 20, 2025 "How to Log" is a surprisingly deep topic in software engineering with many different viewpoints, and they're almost all valid in different situations. I'm going to argue that when processing lots of events, it's best to log every X seconds, rather than every X messages. This is a simple concept, but I've never seen it written down before. Let's quickly look at some pseudocode to understand what I mean. Count-based logging num_events_processed = 0 whi

Fanfic study challenges leading cultural evolution theory

It's widely accepted conventional wisdom that when it comes to creative works—TV shows, films, music, books—consumers crave an optimal balance between novelty and familiarity. What we choose to consume and share with others, in turn, drives cultural evolution. But what if that conventional wisdom is wrong? An analysis based on data from a massive online fan fiction (fanfic) archive contradicts this so-called "balance theory," according to a paper published in the journal Humanities and Social S

Will AI end cheap flights? Critics attack Delta’s “predatory” AI pricing.

Delta has become the first airline to announce that it is using AI to boost profits by personalizing pricing through a pilot program that for months has caused customers to pay different prices for the same flights based on their data profile. Critics have warned that this use of AI goes beyond airline practices that charge people who book flights ahead less than people who book flights at the last minute—and could ultimately mean the end of cheap flights across the board if other airlines foll

6 reasons why I've stuck with Ubuntu-based Linux distros for the last 20 years

Jack Wallen / Elyse Betters Picaro / ZDNET It was October 2004, and I'd been using Red Hat Linux (way before it became Fedora) for years. I was fairly certain that would be my distribution until the world ended. I'd become comfortable with Red Hat. Sure, it had its quirks and was sometimes a bit more difficult than it needed to be (remember, it was over 20 years ago), but it was stable and I'd grown to know it well. But then a new distribution arrived on the scene... Ubuntu. Oddly enough, the

Nearly Half of Americans Budget Based on Vibes. Should You?

A vibe check can help you evaluate lots of things, including your money strategy. A June study by Intuit Credit Karma found that 44% of Americans surveyed have done "vibe-based budgeting."

M.2 SSD Can Self-Destruct by Giving Itself a Burst of Voltage

Worried your data could fall into the wrong hands? A company has developed an M.2 SSD storage drive that can self-destruct by frying its own memory. The product, the P250Q Self-Destruct SSD, is engineered to instantly wipe its memory at the push of a button —either through a software-based erasure or a hardware method that's supposed to physically destroy the flash chip. The product comes from the Taiwanese memory vendor Team Group, which is marketing the SSD to customers working in sensitive

The jank programming language

The jank programming language jank is a general-purpose programming language which embraces the interactive, value-oriented nature of Clojure as well as the desire for native compilation and minimal runtimes. jank is strongly compatible with Clojure and considers itself a dialect of Clojure. Please note that jank is under heavy development; assume all features are planned or incomplete. Where jank differs from Clojure JVM is that its host is C++ on top of an LLVM-based JIT.

Neobank Revolut seeks $65B valuation, a year after its $45B deal

In Brief Europe’s fintech darling Revolut is looking to raise a new funding round that would give it a $65 billion valuation, the Financial Times reports.

Rocket Scientists Hooked Up ChatGPT to the Controls of a Spaceship, and the Results Were Not What You Might Expect

AI Kirk Despite being stumped by simple children's games and uncontrollably hallucinating, AI models could perform surprisingly well when put in charge of navigating space inside a simulated spacecraft, researchers have found. As Live Science reports, a team of scientists from MIT and the Universidad Politécnica de Madrid, Spain, instructed OpenAI's blockbuster AI chatbot ChatGPT to "operate as an autonomous agent controlling a pursuit spacecraft."
