Trees are among the most fascinating life forms on Earth, but what makes them truly fascinating is hiding underground! They are able to break solid rocks with hydraulic roots, all while working together with the underground fungal networks that can stretch for kilometers. Above and below, trees are running biological empires we’re only beginning to understand.
How does something so massive survive with roots growing so shallow? What are trees really made of and how are they able to grow so big?
Losing weight is hard, and obesity is one of the unhealthiest things that can happen to your body. 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 changing people’s lives in a way no diet ever has before. They seem to melt fat away, reduce addiction and even prevent or reverse the negative effects of obesity.
How do these drugs work? What do they do to our metabolism, and could they change public health forever?
Most of the universe is not made of stars, galaxies, or beautiful glowing nebulae. Instead, the majority of it is what seems to be vast, silent emptiness. Huge cosmic voids stretching hundreds of millions of light years across, containing almost nothing at all. But these dark regions are not just empty space. They are dynamic structures that grow, merge, and shape the entire architecture of the universe.
What exactly are cosmic voids and how did they form? What makes them so strange, and what role might they play in the future of the universe?
