About 2,890 kilometres beneath our feet lies a gigantic ball of liquid metal: our planet’s core. Scientists like me use the seismic waves created by earthquakes as a kind of ultrasound to “see” the shape and structure of the core.
Using a new way of studying these waves, my colleague Xiaolong Ma and I have made a surprising discovery: there is a large donut-shaped region of the core around the Equator, a few hundred kilometres thick, where seismic waves travel about 2% slower than in the rest of the core.
We think this region contains more lighter elements such as silicon and oxygen, and may play a crucial role in the vast currents of liquid metal running through the core that generate Earth’s magnetic field. Our results are published today in Science Advances.
In the digital realm, secrets (API keys, private keys, username and password combos, etc.) are the keys to the kingdom. But what if those keys were accidentally left out in the open in the very tools we use to collaborate every day?
A Single Secret Can Wreak Havoc
Imagine this: It’s a typical Tuesday in June 2024. Your dev team is knee-deep in sprints, Jira tickets are flying, and Slack is buzzing with the usual mix of cat memes and code snippets. Little do you know, buried in this digital chatter is a ticking time bomb – a plaintext credential that gives unfettered access to your company’s crown jewels.
The fact that we don’t see anything out there means that if they did exist, they vanished long ago and their signatures have decayed away.
A new type of gel, developed by chemists at the Martin Luther University Halle-Wittenberg (MLU), could help to make lithium-ion batteries safer and more powerful. The gel is designed to prevent the highly flammable electrolyte fluid from leaking.
Pillar-studded surface just hundreds of nanometres thick allows researchers to control direction, polarization and phase of thermal radiation.
Ever wonder why humans shrink as they age? Here’s everything you need to know to help you understand this strange phenomenon.

Where is this camera?
The wonderful people at Finca San Cayetano are graciously hosting our camera at their resort. You can experience this same view in person by staying at one of their 10 luxury cabins and wake up to the sights and sounds of the majestic Fuego Volcano! Here’s their website: https://sancayetano.gt/. The camera is about 8km away from the top of Fuego. Sometimes you’ll be able to hear the eruptions. Due to the speed of sound, it’ll take about 26 seconds after you see an explosion before you hear it.
