The findings challenge long-held assumptions that these building blocks of life on asteroids formed primarily in the presence of warm liquid water.

Show HN: A 3D chessboard sandbox with optional WebGPU path tracinghttps://chessboard3d.app/I wanted to explore GPU ray tracing, so I built a free chess board that feels like playing at a café in real life.The goal was over-the-board (OTB) realism. It’s a physics-based sandbox where you manually drag pieces, move the rook for castling, and clear captured pieces yourself. You can even knock them over. The original idea came from my friend, Drew Olbrich (lunarskydiving.com), who built an SGI-based version of this concept at PDI in the '90s.I spent three decades writing rendering code at PDI/DreamWorks and NVIDIA. I wrote the rendering pipeline from scratch in WebGPU. It defaults to an optimized rasterized "fast path" but if you have a good GPU, you can enable a real-time path tracer in the settings. I implemented this using a 4-layer depth-peeled G-Buffer and Hierarchical Z-Buffer DDA for ray marching, supporting multi-bounce GI and environment map importance sampling.The scene is lit entirely by a single HDRI environment map, with no local light sources. Since I’m a programmerFeb 4, 2026 12:52 PM

Frozen hydrogen cyanide crystals may have helped spark early chemistry for lifehttps://www.spacedaily.com/reports/Frozen_hydrogen_cyanide_crystals_may_have_helped_spark_early_chemistry_for_life_999.htmlLos Angeles CA (SPX) Jan 15, 2026 Hydrogen cyanide is highly poisonous to humans, yet new work suggests it could have played a constructive role in the emergence of life on early Earth and in other cold environments in the solar system and beyond. At very low temperatures this molecule forms solid crystals, and those crystals can host chemistry that would normally be far too slow or even impossible under such frigid conditions.Jan 16, 2026 11:40 AM

A pink aesthetic wallpaper hub for makers/creators, with built-in AI edit toolshttps://news.ycombinator.com/item?id=46599320This might be a bit of an unconventional Show HN, but I think many of us here (myself included) are tired of generic default wallpapers or overly busy designs. We stare at our screens for so long, and a visual environment that feels calm or joyful can have a real impact on focus and mood.So, I built Pink Canvas (https://pinkcanvas.net).The core is simple: a curated library of pink-themed wallpapers. But I wanted to make it genuinely useful, particularly for the tinkerers and creators among us:Precise Curation: Walls are well-tagged (Kawaii, Floral, Minimalist, Fantasy, etc.) and by resolution (Mobile, Desktop, 4K). It saves the time of sifting through Pinterest or Unsplash for that specific look for a specific device.Built-in Maker Tools: Here's the key feature and why I'm posting it here. I integrated AI Generate and AI Edit tools directly into the site.

Choosing the Right Stainless Steel Utility Sink for Heavy-Duty Usehttps://news.ycombinator.com/item?id=46297672In industrial and commercial environments, every piece of equipment plays a role in keeping operations efficient, safe, and hygienic. Among these essentials, the utility sink often works quietly in the background, yet it supports countless daily tasks. From manufacturing plants to commercial kitchens and maintenance workshops, choosing the right stainless steel utility sink for heavy-duty use can make a measurable difference in workflow and durability.Heavy-duty environments place higher demands on sinks than residential spaces. They are used for washing tools, handling raw materials, cleaning components, and managing waste liquids. A well-designed sink must withstand frequent impact, exposure to chemicals, and constant moisture without compromising performance or hygiene. This is where stainless steel stands out as a preferred material across the metal fabrication and industrial equipment sectors.One of the first factors to consider is material grade and thickness.
