Latest science news:
Good morning and welcome to the Live Science news blog.
At Live Science we're a passionate bunch who love reading the latest research and how new discoveries are changing the world around us. We're also lucky enough to write and report on it every day.
But we are just a small bunch of humans, and to paraphrase the late, great Douglas Adams' "Hitchhiker's Guide to the Galaxy", science is big. Really big. You just won't believe how vastly hugely mind-bogglingly big it is.
While we cover the most important or interesting topics of the day, there is no way we can report on it all, not even using AI (and we are very clear about how we use it. TL;DR — we don't).
So rather than letting good news pass both you and us by, why not share it in one place? That way you can let our experienced journalists filter through the noise and bring you the latest science news that matters, wherever it comes from, often with their own spin on things.
Obviously you'll read the best of Live Science here as soon as it's published, but that will sit alongside everything else that matters: Whether it's a scientist voicing their thoughts on a controversial study, another publication's insight into how health research is being impacted by government policy, or a roundup of the latest science news from across the web.
So remember to stay curious and check back every day for good science.
