How did life on Earth originate? Scientists still aren’t sure, and this remains one of the world’s most fascinating and mind-boggling mysteries.

One way of approaching the question is to think generally about how complex systems emerge from chaos. Since the 1800s, scientists have known that entropy is always increasing, with everything in our Universe trending toward disorder over time.

A more nuanced understanding of entropy is helping today’s scientists make progress on the question of the origin of life, as Sean Carroll explains in this Big Think video.

For the first time, scientists have built a detailed, interactive map of a human cell, revealing how thousands of proteins organize and work together.

Using advanced imaging and AI tools like GPT-4, they uncovered hundreds of previously unknown protein functions and identified key cellular assemblies tied to childhood cancers. This map not only changes how we study cell biology but could also transform our understanding of disease at the molecular level.

Scientists have detected a rhythmic ‘heartbeat’ occurring in the centre of the Earth.

It’s not big enough to be felt like an earthquake, but it’s noticeable enough for seismologists around the world to pick up a tiny, measurable ‘blip’ on their radars. Referred to as a ‘microseism’ by geologists, the pulse was first observed coming from the ocean and occurs roughly every 26 seconds.

It’s been quietly pulsing for decades, but scientists aren’t entirely sure what’s causing it.

Lead author Joseph Silk, a professor in the Department of Physics and Astronomy at Johns Hopkins University, explained that this discovery could change our understanding of how galaxies formed. We know these monster black holes exist at the center of galaxies near our Milky Way, but the big surprise now is that they were present at the beginning of the universe as well and were almost like building blocks or seeds for early galaxies.

The study, published in the Astrophysical Journal Letters, analyzed distant galaxies from the early universe observed through the Webb telescope. These galaxies appeared much brighter than expected and contained unusually high numbers of young stars and supermassive black holes.

The findings challenge the conventional idea that black holes formed after the collapse of supermassive stars and that galaxies formed after the first stars appeared. Instead, the analysis suggests that black holes and galaxies coexisted and influenced each other’s development during the first 100 million years of the universe.
