Much like energy and nutrients flow in a continuous cycle between the elements of a natural ecosystem, a free flow of knowledge fuels the growth of a learning ecosystem.

The most common element in the Universe, vital for forming new stars, is hydrogen. But there's a finite amount of it; what if we run out?
Everything acts like a wave while it propagates, but behaves like a particle whenever it interacts. The origins of this duality go way back.
Gamma-ray bursts are so powerful they could vaporize the Earth from 200 light-years away. Recreating them in the lab is not easy.
The first stars in the Universe were made of pristine material: hydrogen and helium alone. Once they die, nothing escapes their pollution.
In our common experience, you can't get something for nothing. In the quantum realm, something really can emerge from nothing.
There's an extra source of massive "stuff" in our Universe beyond what gravitation and normal matter can explain. Could light be the answer?
The new electrically conductive substrate could be the future of hydroponic farming.
Supermassive black holes at the centers of galaxies gobble up whatever matter ventures too close, becoming active. Here's how they work.
The great hope is that beyond the indirect, astrophysical evidence we have today, we'll someday detect it directly. But what if we can't?
Before there were planets, stars, and galaxies, before even neutral atoms or stable protons, there was the Big Bang. How did we prove it?
We confidently state that the Universe is known to be 13.8 billion years old, with an uncertainty of just 1%. Here's how we know.
Particle physicists use gigantic accelerators to investigate the infinitesimal.
The world is aging, and with age comes vision decline. New research may have found how to improve eyesight in an accessible way.
With a massive, charged nucleus orbited by tiny electrons, atoms are such simple objects. Miraculously, they make up everything we know.
The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?
How Stacy Madison — founder of Stacy’s Pita Chips and BeBOLD Foods — discovered that reinvention is not a one-off deal but an ongoing process.
Our greatest tool for exploring the world inside atoms and molecules, and specifically electron transitions, just won 2023's Nobel Prize.
In the wake of the pandemic, the crystal industry boomed, with customers hoping the stones might relieve a little anxiety.
Although many of Einstein's papers revolutionized physics, there's one Einsteinian advance, generally, that towers over all the rest.
It’s not just fun: DNA origami has the potential to revolutionize engineering at the nanoscopic scale.
Magnetic monopoles began as a mere theoretical curiosity. They might hold the key to understanding so much more.
Whether you run the clock forward or backward, most of us expect the laws of physics to be the same. A 2012 experiment showed otherwise.
For over three decades, toxic proteins were believed to cause Alzheimer’s disease. However, recent studies suggest it might be metabolic reprogramming.
Here's why the answer may forever elude scientists.
Economics and religion help to explain the gap.
The Kardashev scale ranks civilizations from Type 1 to Type 3 based on energy harvesting.
A new paper combines two concepts from the edges of astrophysics: Dyson Spheres and black holes. A Type III civilization could combine them.
Even though the brain is only 2% of our total body mass, it consumes up to 25% of our energy.
