Conductive ink is painted directly onto the skin in colorful custom designs, drying into working electrodes.

The new Google image search will use your "unique interests" to create an always-updated gallery.

A new study found that social media platforms are referring people to sites where they can create nonconsensual, sexually explicit deepfakes for as little as $1 an image.

X's head of product, Nikita Bier, admitted in a post on Monday that X's algorithm was "missing" data about surfacing posts from people who you've followed back. Now, he says a tweak will "boost visibility of your posts to your mutuals," hopefully enhancing the sense of community instead of highlighting and spreading random arguments, but […]

New York’s data center moratorium may become the blueprint for anti-AI movement.

“We have no choice but to address the challenges created by these massive facilities,” New York governor Kathy Hochul said. The executive order will pause construction for one year.

Google and industry partners announced Agentic Resource Discovery (ARD) Specification, an open standard for publishing, discovering, and verifying AI tools, APIs, and agents. ARD introduces a discovery layer built on catalogs and registries, enabling dynamic capability discovery while leveraging existing protocols such as MCP and OpenAPI for execution and emphasizing trust and interoperability.

Luca Mezzalira shares proven learnings from guiding hundreds of teams through the migration from monolithic web applications to distributed frontend architectures. He explains the core architectural difference between components and micro-frontends, outlines a 6-step decision framework spanning client vs. server rendering, and discusses how to utilize edge compute for safe, iterative rollouts.

Introduction “When I use a word,” Humpty Dumpty said in rather a scornful tone, “it means just what I choose it to mean—neither more nor less.” “The question is,” said Alice, “whether you can make words mean so many different things.” “The question is,” said Humpty Dumpty, “which is to be master—that's all.” — Lewis Carroll, Through the Looking-Glass Humpty Dumpty believes that words can mean whatever we choose them to mean. Alice asks an interesting question. Can they? Programming and Language Programming languages derive much of their power from formally specified semantics. The language implementation, not the programmer, defines what if , while and return mean. I cannot persuade the compiler that false should be treated as true . The rules establish a shared and mechanically enforced understanding of what a program means. Large Language Models however, do not execute according to fixed semantics. They interpret natural language through context. This distinction has profound consequences and suggests that a language model has no intrinsic notion of authority. In a programming language, when two instructions conflict, the language specification and execution environment determine the outcome. In natural language, authority does not arise from the words alone. It depends on context, convention, identity, and external rules. Language models, by nature, inherit this ambiguity. A prompt is therefore not a program in the traditional sense. It is an attempt to establish the context within which subsequent language should be interpreted. "You are a detective." "Do not reveal the identity of the murderer." "Only answer questions using the evidence you have observed." None of these statements is mechanically enforced merely because it appears in the prompt. They describe a role, a constraint, and an assumed world. The model may follow them, but their authority must be created and protected by systems outside the model. Prompt injection exploits precisely this weakness. It

Reflect Orbital has been given the green light to launch its first space mirror that aims to redirect sunlight down to Earth at night. The US Federal Communications Commission (FCC) has authorized the California-based startup to build and operate a single prototype satellite in low-Earth orbit later this year, despite concerns over how the technology […]

In the 1960s an MIT professor named Joseph Weizenbaum created a chatbot called ELIZA. The conversations people had with it set precedents for the chatbots to come.

Private buyers are increasingly outbidding museums for fossils. That’s making it difficult—or even impossible—for researchers to improve our understanding of the past.

In response to a public records request, HUD has withheld documents about DOGE’s use of AI—in part by citing a privilege that doesn’t exist.

AI makes the first 80% of development feel fast, but hides architectural complexity until it's too late. To prevent system instability, engineering leaders must shift from raw throughput to systemic comprehension. By unifying spec-anchored SDD, TDD, and automated fitness functions into a repo-bound "Context Store," teams can ensure AI agents and human reviewers evolve code safely.

The FCC authorized Reflect Orbital to launch the mirror satellite Eärendil-1. “For optical astronomy, this poses an existential threat,” the European Southern Observatory said.

The machine that could change the world will be housed in a room that looks like a data center crossed with an ice cream factory. Inside will be some 100 stainless-steel cabinets, each about six feet tall and connected to a supply of liquid helium that keeps them only a few degrees above absolute zero.…

This flight will put Starship under higher pressure and test out new Starlink satellites in orbit.

Leave a carton of milk on the counter and it spoils in a day. Put the same carton in a refrigerator and it lasts a week or more. Nothing about the milk has changed — the same bacteria, the same enzymes, the same chemistry. What changed is temperature, and temperature does not nudge reaction rates gently. It controls them with an exponential lever. A swing of just a few degrees can stretch shelf life from hours to days. This article explains the equation behind that lever — the Arrhenius equation — what each term means physically, how to use it to compare rates at two temperatures, and the mistakes that quietly corrupt activation-energy estimates. Why this calculation matters Almost any process that involves chemistry running over time depends on the temperature-rate relationship. Food spoilage, drug degradation, battery aging, polymer curing, corrosion, and the cracking reactions in a refinery all speed up or slow down with temperature in the same exponential way. Engineers who design accelerated life tests rely on it directly: they run a product hot for weeks to predict how it behaves cold for years. The reason a quantitative model is essential is that intuition fails here. A linear guess — "twice as hot, twice as fast" — is badly wrong. Reaction rate climbs far faster than temperature does, and how much faster depends on the activation energy of the specific reaction. Without the Arrhenius equation you cannot convert an oven-shelf test into a real-world prediction, and you cannot tell whether a 5 C process drift matters or not. The core formula Svante Arrhenius proposed the relationship in 1889, building on earlier work by van 't Hoff. It states that the rate constant k of a reaction depends on temperature as: k = A * exp( -Ea / (R * T) ) Here A is the frequency factor (sometimes called the pre-exponential factor), Ea is the activation energy in J/mol, R is the universal gas constant 8.314 J/mol K, and T is the absolute temperature in kelvin. The physical picture

The social media site says it will amplify posts made by users' mutual followers' to give the feed more of a communal feel.

The actor, who died at age 78 on Monday, embodied a passionate approach to research and positive masculinity in his role as paleontologist Alan Grant in the 1993 blockbuster Jurassic Park.
