The mystery of what happens when we go from a superposition to a definite state is known as the Measurement Problem, and it’s arguably the most mysterious outstanding problem in physics. The different interpretations of quantum mechanics...

We’re almost certainly the first technological civilization on Earth. But what if we’re not? We are. Although how sure are we, really? The Silurian hypothesis, which asks whether pre-human industrial civilizations might have existed.

In the far future we may have advanced propulsion technologies like matter-antimatter engines and compact fusion drives that allow humans to travel to other stars on timescales shorter than their own lives. But what if those technologies...

All particles belong to two large groups: fermions like protons and electrons make everything we consider "matter", while bosons like photons and gluons transmit the fundamental forces. And that about covers the universe: matter moving...

They say fusion is 50 years away, no matter when you ask. Then why are billions suddenly being pumped into fusion startups? Yes to train LLMs, but there's a reason the technobrats are bullish on fusion in particular. The fact is, the...

The biggest news in cosmology in recent years is that the mysterious universe-accelerating entity we call dark energy may be fading away. The evidence for this is now strong enough that enormous effort is going into confirming this...

The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as mythical as the grail of legend? What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? Or...

A few weeks ago a large team of gravitational wave astronomers announced something pretty wild. The moderately confident detection of pervasive ripples in the fabric of space time that presumably fills the cosmos, detected by watching...

How and why the giraffe's neck emerged in the first place has been a mystery that generations of biologists have argued over – one that has made us reconsider our understanding of how evolution actually works over and over again.

What happened to the piece of prime prehistoric real estate known as Doggerland? While a massive megatsunami might have drowned it for good, the underlying reason that it now lies under the sea may have actually been the same thing that...

This is the story of how our planet rescued itself from extreme conditions in the Cretaceous Period, at the cost of essentially suffocating the oceans for half-a-million years.

How did ants take over the world? Well, it looks like they didn’t achieve world domination all by themselves. They may have just been riding the wave of a totally different evolutionary explosion.

Around 6,000 years ago, in the Sahel region of Africa, a lone female mosquito buzzed through the lush, green savannah. She couldn’t know it, but the planet itself was about to change in ways that would see her descendants evolve to live...

The journey the thunder beasts took to reach such mega proportions from such humble beginnings forces us to ask an important question, one that paleontologists have been asking for more than a century: from an evolutionary perspective,...

Of course, the ancient Egyptians were probably not the first people to ever wear clothing, but we haven’t found any clothes older than the Tarkhan Dress. So how can we figure out when we first started wearing clothes? Well, it turns out...

What graptolites tell us is a story of incredible changes in the ocean, of periods where the oceans became poisonous and suffocating before eventually clearing up again. They unlock extinctions and recoveries that scientists didn't see....

Turns out, instead of having bats to thank for the existence of butterflies, the groups we should actually be thanking are…bees and beans.

To get fire, which exists only on Earth, it took billions of years of photosynthesis – which means fire can’t exist without life. And fire and life have been shaping each other ever since.

Tiny exoskeleton fragments may have allowed some of the most important microbes in the planet’s history to set sail out into the open ocean and change the world forever.

There was a group of hominins, those creatures more closely related to us than to chimpanzees, that did take a different, parallel journey from our ancestors. Our paths ran beside each other - and potentially even crossed at times - but...

What are animal-like fossils doing in rocks a billion years old, and what does that mean for our understanding of their evolution and geologic time itself? Turns out, there might've been a long, slow-burning fuse that ultimately ignited...

While we think we know a lot about dinosaurs – like how they moved and what they ate – for a long time, we haven’t been able to ID one seemingly basic thing about their biology... Which are males and which are females?

For some, the rise and spread of venomous elapids was just another challenge to adapt to. For others, it was a catastrophe of almost apocalyptic proportions. And we humans are no exception, because it seems that when elapids slithered...

When did practicing medicine - in its varied, complex forms (from sharing medicinal plants to the earliest surgeries) - become something that we actually started doing? While it’s a hard question to answer, it’s possible that our...
