Data centers in Space? Sophia Space and Apex plan on busing them in

Can data centers really be built in space? Pasadena-based Sophia Space is partnering with Apex to test the idea by launching modular AI computing systems into low Earth orbit in 2027. Using radiation-hardened compute TILEs cooled by passive radiative systems and mounted on scalable satellite buses, the companies aim to prove that edge computing can operate reliably in space. While challenges remain, the project represents an important step toward distributed orbital computing networks that could support everything from climate monitoring and pollution tracking to autonomous spacecraft navigation in an increasingly crowded orbital environment.

This guide explores practical ways landlords can improve cash flow without major renovations, including working with property managers, adjusting rental rates strategically, reducing operating expenses, and uncovering new revenue streams. Whether you're running an Airbnb, a vacation cabin, or a long-term rental, sustainability isn't just good for the planet—it can be good for your bottom line.

Is your shawarma wrapped in forever chemicals? The hidden microplastics in street feed

Shawarma is one of the world's most popular street foods, but the greatest health risk may not be the meat, pickles or tahini. Scientists are increasingly concerned about PFAS "forever chemicals" and microplastics that can migrate from food packaging into hot, greasy takeaway meals. As awareness grows about hidden toxins in everyday products, even your favorite shawarma wrap may be part of a much larger environmental and public health story.
