"Unbiased" is a silly word whose use shows a lack of understanding of systems of power.

Dr. Angela Collier and Dr. Fatima both make good videos about science and science communication.

The best communicators are ones that stick to their own field. Neil Degrasse Tyson is kind of a bad one for that, as well.

There's a lot of fields and subfields, so that means not any one particular person, unfortunately.

Science and futurism with Isaac Arthur will always be my favorite YouTuber. The guys personal history is fascinating, he's always been very involved with his community. He does video essays about different aspects of the future, from spaceship designs that work under currently known physics, to what the future of sports looks like. He covers megastructures like Dyson spheres(or swarms more likely), he's touched on micro and nano technology, I bet you haven't even heard of a Santa Claus machine. I recommend you start with his earlier stuff although it's not mandatory. It will give you a good idea of the logical frameworks he works within. Plus hearing "whalegun" literally never gets old.

There's also PBS spacetime. Matt Dowd is an amazing person and a very effective physics communicator. You can come away from his videos with nearly a college level education, but it's a lot of work because it's not easy to understand all the time. He's breaks things down excellently, but the topics he covers are so complex that you can only reasonably break them down so far. He does quantum videos, lots of black hole stuff, breaks down everything we know about dark energy and matter, discusses the heat death of the universe, and gets into Einstein Rosen bridges and the holographic theory.

I don't know what "bias" is in this context, science isn't really political and doesn't have a "message" so there's not really anything to push. Either you communicate the truth, or you're a grifter. There's isn't really an in between. That being said, this next person does make their political beliefs more known, although rarely does that get brought up in their videos.

Joe Scott from Answers With Joe is awesome! He does a lot more wide ranging stuff, like weird occurrences(missing people, time travelers, alien abductions) but he present them in a very unbias way in the sense that he tries to tell all sides of the story. He's not a conspiracy theorist, but he does find some of the more wacky conspiracies interesting. He's also done videos on AI before LLMs started taking over, he covered Omuamua back when that happened, he's discussed how climate change will impact different areas. He's a much more layman-level YouTuber than the others in this list, but he is every bit as informative and entertaining.

Styropyro does lasers and extremely high voltage, The Plasma channel does things that might shock you, the Thought Emporium does a ton of crazy cool stuff like gene editing and growing a real mini rat brain to play DOOM. IDidAThing does foot stuff. CodysLab is interesting. The video content is incredible, but Cody does give me some mildly unsettling vibes.

Shout-out to The GrandLine Review. They're not sciencey at all, they cover One Piece. They're cool and funny though, check em out if you're into lore videos.

If anyone liked these recommendations, let me know. My feed is nothing but this stuff, and I've got a lot of YouTubers who I watch.

I like Angela Colliers videos https://www.youtube.com/channel/UCtscFf8VayggrDYjOwDke_Q

For space/astronomy news, I recommend Doctor Becky https://youtube.com/@drbecky and Fraser Cain. https://youtube.com/@frasercain

Becky handles mostly astronomy news, Fraser handles mostly space flight news. Both are pretty decent at staying more objective.

Common sense skeptics are very biased against BS.

I watch Upper Echelon on YouTube. I wouldn't say he's unbiased though. His videos are all criticisms of tech things.

Seems well researched though and he talks about things I've not seen addressed as much on other channels.

Most of his videos are on AI.

Here is his latest. About an AI "reddit -like" platform called moltbrook. And how tech bros trying to say it shows AI emergence is a lie. It's actually humans running the site. And it's mostly just scam AI bots running rampant.
