In a clip from today’s podcast, Oli and Ava dive into parliament’s controversial Online Safety Act. The law means that age verification is now required when accessing explicit content online. But is this really the best way to protect young people? Or is it just a case of punishing the wrong platforms?
Oli and Ava unpack how lawmakers have shifted the focus from social media giants where users are often served graphic content without consent to adult websites like Pornhub. They highlight how the Online Safety Act is less about actual safety and more about political optics, especially after tech companies failed to self-regulate.
Ultimately, who really gets locked out? Tech-savvy teenagers or a middle-aged man browsing on the family laptop? For better or worse, the UK is now leading the world in internet regulation, setting a precedent that other countries are watching closely.

There are many cases of convergent evolution, but did you know the caffeine made by plants is one of them? In this video, we take this channel’s first steps covering the fascinating science of botany, and talk about how ancient ancestral genes were copied and mutated multiple times independently, leading to the caffeine we know and love today.

We have known for a long time that plants move, but today we are discovering that they can sense, touch, and taste. They react to stimuli of various kinds.
They also have a keen ear, memory, and can perceive shapes. Plants interact much more than we believed with the external world.
We knew they were sensitive to temperature, sunlight, humidity… Recent research proves that plants possess many other surprising senses, leading us to look at them with fresh eyes.
