Nonstick cookware has its place in the kitchen, but its limitations should keep it from being your everyday pan. Nonstick cookware can tank a recipe when misused, leaving meat and vegetables without a proper sear. Some foods can damage the surface of your nonstick skillet, leading to a shorter lifespan or the release of nonstick materials into your food.

An Annual Blast of Pacific Cold Water Did Not Occur, Alarming Scientists

news.ycombinator.com Sachi Kitajima Mulkey 2025-10-01 16:54:31

Each year between January and April, a blob of cold water rises from the depths of the Gulf of Panama to the surface, playing an essential role in supporting marine life in the region. But this year, it never arrived. “It came as a surprise,” said Ralf Schiebel, a paleoceanographer at the Max Planck Institute for Chemistry who studies the region. “We’ve never seen something like this before.” The blob is as much as 10 degrees Celsius colder than the surface water.

Liquid Glass in the Browser: Refraction with CSS and SVG Apple introduced the Liquid Glass effect during WWDC 2025 in June—a stunning UI effect that makes interface elements appear to be made of curved, refractive glass. This article is a hands‑on exploration of how to recreate a similar effect on the web using CSS, SVG displacement maps, and physics-based refraction calculations.

A robot walks on water thanks to evolution's solution

Rhagobot isn’t exactly the first thing that comes to mind at the mention of a robot.

Experimental Hook-and-Loop Attachment System for Walls and Floors

This ReCon Project, developed at Austria's Graz University of Technology (TU Graz), proposes a hook-and-loop fastening system for wall surfaces. While a true hook-and-loop arrangement (like that used in Velcro) isn't possible with rigid surfaces, the research team came up with a close approximation. Protrusions were cast into concrete, and a flexible sheet material was 3D printed with corresponding protrusions on one face, allowing the sheet to be non-permanently adhered to the concrete. "Such

These Chunks of Ice Move All By Themselves, Thanks to a Cool Engineering Trick

It looks like something straight out of a Ouija board horror movie, but frosty—researchers have figured out how to make ice move by itself. A video capturing the creepy dynamic features an ice disk melting on a metal surface etched with an asymmetrical herringbone pattern. The ice and its small puddle slowly start to move sideways before suddenly picking up speed and slingshotting across the metal plate. The researchers suggest that this sort of independent movement could one day generate power

Scientists have figured out how to make frozen discs of ice self-propel across a patterned metal surface, according to a new paper published in the journal ACS Applied Materials and Interfaces. It's the latest breakthrough to come out of the Virginia Tech lab of mechanical engineer Jonathan Boreyko.

Mesmerizing Hypnoloid, a Kinetic Desktop Sculpture

This Hypnoloid object is sort of the opposite of a spinning top. Whereas a top contacts the surface it's balancing on only at its point, the Hypnoloid contacts the surface with every square millimeter of its surface area. The shape is called an oloid, and it's a bit difficult to understand. The 20th-century German sculptor, inventor and mathematician Paul Schatz, who discovered it, describes it thusly: "If the distance of two centers of disk is equal to the radius, then the convex hull produce

Microsoft Needs to Make Affordable 5G Surface Laptops a Reality

Laminar Flow Airfoil

Laminar Flow is the smooth, uninterrupted flow of air over the contour of the wings, fuselage, or other parts of an aircraft in flight. Laminar flow is most often found at the front of a streamlined body and is an important factor in flight. If the smooth flow of air is interrupted over a wing section, turbulence is created which results in a loss of lift and a high degree of drag. An airfoil designed for minimum drag and uninterrupted flow of the boundary layer is called a laminar airfoil. The
