Even our oceans are mostly barren voids where almost nothing can survive. But as we discover and research more exoplanets, we are beginning to wonder whether there could be worlds that are far better suited for life than Earth ever was, and where ecosystems flourish on a scale we can barely even imagine. Could there be a Super-Earth that is not just habitable, but truly ideal for life? What would such a world look like, and what kinds of creatures would we find there?

It increases your risk of diabetes, heart attacks, cancer, and can lead to a series of other health complications. But today, the new weight loss drugs are often used to tackle the obesity. How do these drugs work? What do they do to our metabolism, and could they change public health forever? IMPORTANT: This is an updated version from the original video we released over a month ago. The first version did not contain wrong information but our framing was not good enough – after hearing your feedback it was clear that we didn’t communicate the topic well – so we revised the script, made the video longer and added more information and clarifications at key points. All changes and the link to the original video (now unlisted) can be found here: Old Version of the Video: https://youtu.be/9t5m33ccUYA Sources & further reading: https://sites.google.com/view/sources-ozempic/ This whole experience was annoying because we didn’t plan to make a controversial video – this caused us a lot of extra work but was obviously necessary.

We Made A New Channel!

Jan 16, 2026

For years, we’ve been dreaming of a second channel. A channel where we could tell different kinds of stories and dive into something else we deeply care about: history. Because the story of the past is also the story of us, of humanity. Welcome to the nightshift. 🌚 Our first video dives into the extraordinary story of Zheng Yi Sao, a young woman who built the largest pirate confederation the world has ever seen. Her floating shadow state of 1,800 ships and 70,000 pirates pushed the Chinese Empire to its limits and reshaped trade in the South China Sea.

They build their bodies from thin air, move water with pressures that would crush a human, and grow using a fascinating system of living cables wrapped in layers of corpses. Under their bark lies a razor-thin strip of living cells, working endlessly to move water hundreds of meters, build indestructible wood, and coordinate millions of functions. How do trees work, and what are they even made of? What makes these ancient giants so resilient, and maybe even immortal?
