NEXT HORIZON — SCIENCE & FUTURE Can We Predict a Baby’s Future From DNA — or Rewrite It? From carrier screening and embryo testing to CRISPR and “designer babies”: what science can really tell us in 2026, what it cannot, and what may come next. “Designer baby” used to be an easy science-fiction phrase. In 2026, it is getting harder to laugh off — not because fertility clinics can build children to order, but because separate pieces of that future now exist in real medicine. Inherited disease risk: minimize Cancer risk: low Eye color: green Hair: dark Height: above average Cognitive potential: high   None of those sliders exists. But almost every line on that imaginary screen now points to a real field of research: inherited-disease screening, embryo selection, polygenic prediction, reproductive genetics or genome editing. Depending on the test, prospective parents can be screened across hundreds of genes for ...

  NEXT HORIZON — SCIENCE 3D-Printed Organs: How Close Are We to Printing a Human Heart, Liver, or Kidney? A concept illustration of organ bioprinting: a 3D bioprinter fabricates a heart-like structure layer by layer in a high-tech lab. A kidney fails. Today, that can mean dialysis, a donor waiting list and a long search for a compatible organ. Now imagine a different route: doctors take a small sample of your cells, grow them in the laboratory, combine them with a printable biological material and use that mixture to build a replacement designed for your body. After printing, the tissue would still need to mature, develop a usable blood supply and prove that it can do the work of a real kidney before surgeons could even consider implantation. No donor organ would be needed, and using the patient’s own cells might reduce the risk of immune rejection.

Space Tourism in 2026: What It Costs, Who Can Fly, and Why It Still Isn’t Normal For the first time in history, private space travel is no longer science fiction — but in 2026 it still remains rare, expensive, and far from routine. Space tourism has been “almost here” for so long that the phrase started to sound like a running joke. In the 2000s, wealthy civilians were already buying rare seats on Soyuz. In the 2010s, a new generation of private companies promised something much bigger: regular commercial flights for people who had never been professional astronauts. Then, in 2021, Richard Branson flew, Jeff Bezos flew, and private crews began riding SpaceX Dragon into orbit. For a moment, the industry seemed to have crossed the line from science fiction into transportation. It did cross one line. It just was not the one people expected. Private citizens can now reach space, spend days in orbit and visit the International Space Station. But space tourism has not become a miniature v...

How ChatGPT Actually Works: From Your Prompt to an AI Answer Next Horizon editorial rewrite - September 2026   ChatGPT can feel strangely simple. You type a question into a box. A few seconds later, a polished answer appears. That simplicity is deceptive. Behind the chat window is not one digital brain sitting somewhere on a server and "looking up" the answer. A modern ChatGPT response can involve a language model, a large temporary context, stored memory, safety instructions, external tools, web search, files, code execution and several rounds of internal computation before you see the first sentence. The basic idea, however, is still understandable without a degree in machine learning. At its core, a language model learns patterns in enormous amounts of data and uses those patterns to predict what should come next. Everything else - instruction following, reasoning, memory, tools and product features - is built around that foundation.

Best AI Video Generators in 2026: Free & Paid Tools That Actually Work A practical Next Horizon guide to making AI video — what you can use for free, what is worth paying for, and how to turn a handful of generated clips into something people will actually watch. AI video generators in 2026 can create everything from cinematic scenes and product ads to social videos and virtual presenters. AI video in 2026 looks like magic — right up until you try to make one A five-second AI clip can now look like a frame from an expensive commercial. Then you open the generator yourself, discover that the free credits are nearly gone after a few attempts, your character changes face between shots, and the “one-click movie” from the demo suddenly looks a lot less one-click.

BIOLOGY   /   LONGEVITY   /   GEROSCIENCE Why We Age - and Whether Science Can Actually Slow It A scientific guide to the biology of aging, longevity research, epigenetic clocks, senolytics, rapamycin and the first human trial of partial cellular reprogramming.   A visual overview of human aging as a biological process driven by cellular damage, mitochondrial dysfunction, senescence, inflammation and loss of resilience. At 25, a bad night's sleep can feel like an inconvenience. At 75, the same kind of physiological stress may take longer to recover from. That shrinking ability to repair, adapt and bounce back is one of the most useful ways to think about aging. Gray hair and wrinkles are visible; the deeper story is a body slowly losing resilience. For most of medicine's history, doctors have treated that decline one failure at a time. High blood pressure gets one drug. A tumor gets surgery or chemotherapy. A worn joint gets replaced. Geroscience asks a ...
