“If given a chance, nature can rebound, and nature can rebound dramatically.” Biologist Sean B. Carroll discusses the resilience of nature and how humans can help it thrive. Humans litter, […]
Abstract representation of a cosmic event with a burst of particles emanating from a central point, blending astrophysical imagery with geometric designs.
If you bring too much mass or energy together in one location, you'll inevitably create a black hole. So why didn't the Big Bang become one?
A deep space image showing numerous galaxies of different shapes and sizes scattered across a dark background, with many stars and cosmic objects, including the ancient Methuselah star, also visible throughout.
The Universe is precisely dated at 13.8 billion years old, but astronomers claim the Methuselah star is 14.5 billion years old. What gives?
A sailboat is silhouetted against a vibrant sunset over a calm sea, with other boats and their reflections visible in the background. The sky and water have a golden hue.
Ancient currents seemed to move in concert with a 2.4 million-year dance between the Red Planet and Earth.
A robotic hand and a human hand reach towards each other against a dark background.
The preservation and celebration of life, and not greed, should be our primary decision-making value. 
Ancient stone structure with stairs under a blue sky with scattered clouds, surrounded by vegetation.
How (not) to end up in the ash heap of history.
A gradient bar titled "The Future" shows a range from "Apathy" in red on the left to "Fear" in red on the right, with green in the middle. An arrow points to the green area.

Predicted way back in the 1960s, the discovery of the Higgs boson in 2012 completed the Standard Model. Here's why it remains fascinating.
Three minimalistic white figurines sit on small platforms in front of a grid of squares, some orange, on a light grey background.
Acclaimed writer Mauro Javier Cárdenas used AI in his latest work to surprising effect.
A serene beach scene at dusk with a distant pier, a few people walking along the shoreline, and gentle waves hitting the sand. The sky is cloudy with rays of light breaking through, hinting at the subtle potential for tidal power beneath the surface.
For well over a century, engineers have proposed harnessing the ocean’s tides for energy. But the idea hasn’t seemed to register in many places.
Animated countdown timer at zero with the word "MINUS" appearing after the countdown, displayed over a background transitioning from red to blue.
The threats Mars astronauts face — and how NASA is working to solve them.
A Facetime Video call screen showing an incoming call from "ChatGPT" with an AI icon, featuring a red decline button and a green accept button.
We will believe in AGI when it calls on Facetime.
Abstract green fractal design with smooth, curved lines converging at a central point, resembling a flowing, symmetrical pattern against a dark background, inspired by AI physics.
A new technique that can automatically classify phases of physical systems could help scientists investigate novel materials.
A black and white photo of a young child holding a vintage telephone receiver to their ear, with an excited expression. The background features graphic designs of sound waveforms and orange flames, evoking the intense energy of death metal.
If music is a window onto truth, what does screaming reveal?
Stellar explosion
The expanding Universe, in many ways, is the ultimate out-of-equilibrium system. After enough time passes, will we eventually get there?
A diagram of the solar system illustrates the heliosphere, detailing the termination shock, heliopause, and bow shock, along with the paths of Pioneer 10, Pioneer 11, Voyager 1, and Voyager 2. This visual representation underscores key aspects of fundamental science in our cosmic neighborhood.
Some think the reason fundamental scientific revolutions are so rare is because of groupthink. It's not; it's hard to mess with success.
Close-up of a person's beard and glasses on the right side with numbers "7", "30", and "65" shown in varying typographical styles across the center, subtly referencing the 7-38-55 rule. The background is abstract with dark and light tones.
If words are really only 7% of communication, then why would anyone need to learn a foreign language?
A close-up of a metallic conical structure, set against a dark wireframe background. The structure has reflective surfaces and appears to be part of a scientific or industrial apparatus.
Scientists are searching for dark matter particles that are trillions or even quadrillion times lighter than the more traditional searches. 
LHC insides
CERN's Large Hadron Collider is the most powerful particle accelerator ever. To go even further, we'll have to overcome something big.
