Chemical energy, where electrons transition in atoms, powers the reactions we see. But two other types hold more promise than all the rest.

There is nothing more important to science than its ability to prove ideas wrong.
Ever since the start of the hot Big Bang, time ticks forward as the Universe expands. But could time ever run backward, instead?
We know it couldn't have began from a singularity. So how small could it have been at the absolute minimum?
The ten greatest ideas in science form the bedrock of modern biology, chemistry, and physics. Everyone should be familiar with them.
Ancient organic chemistry.
Extreme home environments — either very supportive or harshly negligent — tend to produce more sensitive kids.
U.S. nuclear power plants are built to survive external attacks. Even missiles or a commercial aircraft strike would not cause a meltdown or radiation leak.
From the tiniest subatomic scales to the grandest cosmic ones, solving any of these puzzles could unlock our understanding of the Universe.
NASA will use energy from Earth's gravity to launch the Lucy spacecraft in October of this year.
Photosynthesis is powerful but very inefficient. Humans can improve on this biochemical process to help the planet.
The fully functional plant will serve to demo TerraPower's nuclear tech.
Everything else in the universe is either a particle or field. Dark energy behaves as neither, and it may be a property inherent to space itself.
It could evolve, strengthen, decay, or not be alone. Our known Universe contains matter, radiation, and dark energy. While matter (both normal and dark) and radiation become less dense as […]
All of these conflicts have a long history. They may also have a long future.
The recently discovered Oort cloud comet, Bernardinelli–Bernstein, has the largest known nucleus: 119 km. Here's what it could do to Earth.
We have two descriptions of the Universe that work perfectly well: General Relativity and quantum physics. Too bad they don't work together.
The strongest tests of curved space are only possible around the lowest-mass black holes of all. Their small event horizons are the key.
Forget about the terawatt lasers we're making on Earth. This natural one is thousands of times more powerful than the Sun.
Practically all of the matter we see and interact with is made of atoms, which are mostly empty space. Then why is reality so... solid?
Aptera expects to begin delivering its solar-powered car later in 2022.
Even though the leftover glow from the Big Bang creates a bath of radiation at only 2.725 K, some places in the Universe get even colder.
Einstein’s theory of general relativity passes another test, with implications for dark matter and dark energy
The theory is accurate within at least one part in a quadrillion.
Oxygen isn't strictly necessary for combustion, but it is ideal. Any advanced (alien) civilization probably uses oxygen to burn things.
Nothing in this Universe is eternal — not even the stars.
Everyone loves a good origins story.
The same (former) NASA engineer who previously claimed to violate Newton's laws is now claiming to have made a warp bubble. He didn't.
If dogs are out in coats and boots, how are the squirrels feeling?
As technology advances, the use of laser weapons in space becomes more likely.
A recent study overviews the thinnest X-ray detector ever created.
