New Nuclear Rocket Concept Could Slash Mars Travel Time in Half

gizmodo.com Passant Rabie 2025-10-02 02:00:58

Engineers from Ohio State University are developing a new way to power rocket engines, using liquid uranium for a faster, more efficient form of nuclear propulsion that could deliver round trips to Mars within a single year. NASA and its private partners have their eyes set on the Moon and Mars, aiming to establish a regular human presence on distant celestial bodies. The future of space travel depends on building rocket engines that can propel vehicles farther into space and do it faster. Nucl

‘Selling coffee beans to Starbucks’ – how the AI boom could leave AI’s biggest companies behind

techcrunch.com Russell Brandom 2025-10-02 03:00:00

How much do foundation models matter? It might seem like a silly question, but it’s come up a lot in my conversations with AI startups, which are increasingly comfortable with businesses that used to be dismissed as “GPT wrappers,” or companies that build interfaces on top of existing AI models like ChatGPT. These days, startup teams are focused on customizing AI models for specific tasks and interface work, and see the foundation model as a commodity that can be swapped in and out as necessary

Kaitlyn Cimino / Android Authority When Apple drops a new health feature, the ripple effect is rarely subtle. The company’s latest announcement that hypertension notifications are coming to the Apple Watch lineup is one of those moments. For years, smartwatches have toyed with the promise of more medical-grade metrics. My hope is that now, thanks to Apple, blood pressure monitoring is about to become mainstream.

I’m looking for a new programming language to learn this year, and Gleam looks like the most fun. It’s an Elixir-like language that supports static typing. I read the language tour, and it made sense to me, but I need to build something before I can judge a programming language well.

Visual programming is stuck on the form

news.ycombinator.com Wil Chung 2025-10-01 23:53:31

Underlying great creations that you love—be it music, art, or technology—its form (what it looks like) is driven by an underpinning internal logic (how it works). I noticed this pattern while watching a talk on cellular automaton and realized it's "form follows function" paraphrased from a slightly different angle. Inventing a form is a hard task, so you must approach it obliquely—by first illuminating the underlying function. This made me realize something crucial about visual programming: it’

Using a range of advanced methodologies, the research found that, in coronary artery disease, atherosclerotic plaques containing cholesterol may harbour a gelatinous, asymptomatic biofilm formed by bacteria over years or even decades. Dormant bacteria within the biofilm remain shielded from both the patient’s immune system and antibiotics because they cannot penetrate the biofilm matrix. A viral infect

Six decades have now passed since some of the most iconic Project Gemini spaceflights. The 60th anniversary of Gemini 4, when Ed White conducted the first US spacewalk, came in June. The next mission, Gemini 5, ended just two weeks ago, in 1965. These missions are now forgotten by most Americans, as most of the people alive during that time are now deceased. However, during these early years of spaceflight, NASA engineers and astronauts cut their teeth on a variety of spaceflight firsts, flying
