Female science communicators are taking social media by storm in 2025

Female science communicators are dominating social media in 2025 - and these are far from ordinary creators, both in style and in scale.

This year, FeedSpot’s media database put women front and centre: among the top 50 STEM influencers, no fewer than 41 slots were held by accounts led by women presenters. Across TikTok, YouTube and Instagram, female science communicators are pulling in audiences of millions with a mix of humour and insight.

You may already follow Emily Calandrelli, Katie Mack, Emily Graslie, Dianna Cowern aka Physics Girl, Ali Ward or Simone Giertz, but with International Women’s Day in mind, it’s a good moment to highlight a few rising sci-com favourites who may not yet be on your radar.

Female science communicators among FeedSpot’s top STEM influencers

Second overall on FeedSpot’s list of top STEM influencers is Mrs. Nancy Bullard, better known as Mrs. B - an easy-going, likeable science teacher from North Carolina. She’s built an audience of around 650,000 followers on Instagram, just over a million followers on YouTube, and 3.4 million on TikTok.

Her channel isn’t just another home for school science-fair-style activities (though there are plenty of those too), featuring everything from fireworks in a jar to marshmallow catapults and candles that burn underwater.

One of Bea’s most-watched TikTok videos, with 13.4 million views, shows her handling real human brains while explaining how organ donation works. In another clip that went viral, she deals with her own placenta - blue gloves included, of course.

In the United Kingdom, mathematician Hannah Fry tackles science’s big questions, such as, "Are numbers actually real?", "Is it possible to avoid hangovers?", and "What do Barbie and Ken have in common with a fruit fly?"

Fry has a knack for turning intimidating topics into something approachable and useful - even for people who never felt maths was their strongest subject at school.

In an interview from several years ago, when asked why girls should study science and maths, Fry said, "You have to realize that being female at the moment is a superpower. Everything is willing you forward, and I think that there has never been a better time to want to get into science, technology, engineering, and mathematics."

As of 2025, Fry is the Professor of the Public Understanding of Mathematics at the University of Cambridge, and you can follow her on YouTube, Instagram and TikTok.

Science creators to watch: foraging, space, and hands-on engineering

It’s now been two years since American forager and vegan cook Alexis Nikole Nelson won the 2022 James Beard Award for Best Social Media Account - and in that time her TikTok following has climbed from 3.3 million to 4.4 million.

LOL @ my nonsense description of the taste 🤣🤣 🌲

Nelson isn’t a formally trained scientist, but her enthusiasm for finding wild food in the "VERY untamed wilderness of scenic Ohio" is likely to motivate any aspiring naturalist. Her tutorials - such as "gathering prickly pears without ruining your life" - aim to teach people about the remarkable plants around them, while also celebrating the Black and Indigenous roots of foraging.

Whether she’s helping viewers spot poisonous plants, brew dandelion wine, or make seawater pickles, Nelson’s bright, energetic lessons can change how you notice - and taste - the world around you.

You can keep up with Nelson on TikTok, Instagram and YouTube.

Meanwhile in Australia, astrophysicist Kirsten Banks has people gazing skywards even as they scroll. With a PhD in astrophysics, Banks shares space science with her followers - and she does so through a perspective that’s distinctly her own.

As a proud Wiradjuri woman, Banks is continuing a legacy shaped by her Aboriginal ancestors, who are often described as the ‘earliest astronomers’.

"In Australia alone there are more than 250 Indigenous groups that have used the stars for the last 65,000 years, and their knowledge is still exercised to this day," Banks said in a TED Talk in 2020.

🚨 Mind-blowing update about Saturn's rings! 🚨 Did you know that sharks have been around longer than Saturn's rings? 🦈 At least, that's what we thought. But new research suggests Saturn's rings might be as old as the Solar System itself, over 4 billion years! 🤯 The Cassini spacecraft revealed Saturn's rings look super clean, which made scientists think they were "young." But it turns out Saturn might have a trick up its sleeve! 💫 Meteorites smashing into the rings at high speeds could turn cosmic dust into charged particles. Saturn's magnetic field then sweeps them away, keeping the rings sparkling clean, like a cosmic Roomba. Someone needs to invent a robot vacuum called Saturn! But it looks like that has already happened?! What do you think? Does this new research ruin the shark vs. Saturn fun fact or make Saturn even cooler? #Saturn #SpaceFacts #NASA #Space #Astronomy

Her favourite Aboriginal constellation is Gugurmin in the Wiradjuri language - the Celestial Emu - traced out in the Milky Way. Its place in the night sky helps indicate when it’s the right time to go searching for emu eggs.

Xyla Foxlin is cool - there’s no more concise way to put it. A mechatronics engineer, pilot, rocketeer, woodworker and self-described ‘creator of chaos’ with a love of the arts, Foxlin has a "disdain for the way engineering is taught in schools". She’s set on encouraging others to build things… really any things - whether that’s a Christmas tree rocket or a foam version of yourself.

Foxlin doesn’t treat usefulness as the only goal; for her, the joy of learning and the fun of making are reason enough.

"My big thing is that femininity and engineering are not mutually exclusive. I'm still the only one in a dress at design reviews or the only one wearing all pink in the shop. We should be teaching our girls that it's OK to like princesses and power tools," she told Cleveland Magazine in 2017.

You can find Foxlin on TikTok, Instagram and YouTube.

Happy scrolling this International Women’s Day!
