Nuclear Science

Nuclear science is the study of sub-atomic particles and their application in various disciplines. Here you can learn about nuclear power plants, atomic theory and radiation.

Closing In on Higgs, Six Years Later

We caught up with everyone's favorite boson to see what it's been up to and exactly how it decays.

Particle Acceleration Takes a Leap Forward

CERN researchers have successfully tested a new way of accelerating electrons to high energies through proton-driven plasma wakefield acceleration.

ITER Nuclear Fusion Plant Is Halfway Finished

The International Thermonuclear Experimental Reactor plant aims to demonstrate that nuclear fusion could be a viable source of power in the future.

How the Deep Underground Neutrino Experiment Will Work

The seriously ambitious experiment aims to understand the mysterious neutrino and maybe even figure out why matter won out over antimatter during the Big Bang.

Fukushima Radiation Readings Are Extremely High … But Let's Not Freak Out

New data shows extremely high radiation levels inside one of the reactor containment vessels. Are post-tsunami radiation levels spiking? Not so fast …

10 Reasons the Multiverse Is a Real Possibility

In 1957, Hugh Everett first wrote about the multiverse — different realms where every choice spawns a separate universe in which another version of ourselves does something different. It sounds crazy, but here are some reasons it might be true.

30 Years After Chernobyl, Wildlife Thrives

The site of the largest nuclear accident in history is now home to diverse wildlife. Can studying the animals help researchers discover how radiation affects us all?

Large Hadron Collider's Spring Break Finally Ending

One of the world's most complex devices is gearing up again for some serious collisions.

Is Fusion Fact or Fantasy?

Early fusion reactor experiments ran into a big problem: It took more energy to get fusion started than was produced by the fusion itself.

Where do they get the particles for accelerators?

When physicists want accelerator particles, they head to OK Quark, answer questions about what they're looking for, and hope for a match. Nah, wait … that's not it at all.

What is supersymmetry?

Of all the superheroes we have in the universe, supersymmetry might be the one that will save us from total annihilation. Not because it fights bad guys, but because it just might explain how the tiniest parts of the cosmos work.

What is the multiverse?

Want to see two physicists fight? Ask them what they think about the multiverse. Isn't it time you formed an opinion, too?

What does the Higgs boson look like?

When something as important as the Higgs rocks our world, we want to know every last thing about it, including what it looks like. So?

Why is the LHC 27 kilometers in circumference?

Twenty-seven kilometers is more than five 5K races. Most humans aren't interested in running that much, so why do a bunch of speeding protons require that considerable distance?

What do particle physicists see when collisions happen?

The Large Hadron Collider sounds so exciting, with its millions of near-light-speed collisions per second. But what do scientists really see while that's going on?

Can the LHC prove string theory?

String theory is the basic idea that everything in the universe is fundamentally composed of vibrating strings. Can the LHC prove that it's true?

Can supersymmetry and the multiverse both be true simultaneously?

Supersymmetry: the idea that the particles we know about have as-yet-underscovered force partners. Multiverse: exactly what it sounds like. Can they coexist?

Has the LHC found any practical uses for the Higgs boson?

When scientists announced that the Large Hadron Collider had found evidence of the Higgs boson, we cried right along with elated physicists everywhere. But ... then what?

How do they keep track of the particles in the LHC?

To the uninitiated, the LHC can look like a junk drawer ... a junk drawer that's full of tiny, rapidly decaying particles that move at light speed. How do scientists know what's where?

5 Discoveries Made by the Large Hadron Collider (So Far)

The Large Hadron Collider isn't just a one-trick (Higgs) pony. Find out what else has happened where hundreds of millions of particles may collide any given second.

How does nuclear waste disposal work?

Nuclear waste epitomizes the double-edged sword of modern technology. It's a toxic and radioactive byproduct of nuclear medicine, nuclear weapons manufacturing and nuclear power plants.

5 Baffling Subatomic Particles

Batman and particle physicists have a lot in common. While Batman brawls with anarchist clowns and mutated ecoterrorists, CERN scientists chase down their own notable adversaries. Get to know five of them.

What exactly is the Higgs boson?

Who wants to reduce our complicated universe down to its simplest building blocks? A bunch of particle physicists, that's who. Why is the Higgs boson critical to that goal?

How Uranium Mining Works

Thanks to our voracious appetite for energy, the element long linked with nuclear weapons is taking on a new role. Where does the hunt begin for uranium?

How Radiation Sickness Works

We're all exposed to tiny levels of radiation, but a blast of it can leave you in agony -- that is, if it doesn't kill you outright. What is it, what causes it and how can we treat it?
