Since our ancient human relatives began using stone tools to perform tasks, humans have harnessed scientific knowledge and new technologies to expand the boundaries of our understanding of the natural world. From quantum computing and microplastics to artificial intelligence and memory, explore these topics and more with our concise yet informative overviews and expert-curated resources.
Hours of research by our editors, distilled into minutes of clarity.
When bent, the glass tube inside the stick breaks, releasing hydrogen peroxide into the surrounding solution. The ensuing reaction creates unstable molecules that decompose and release energy, which is then absorbed by molecular dyes that emit light when their excited electrons return to lower energy states.
The En-ROADS tool lets you role-play as a global decision maker to explore the long-term effects of various policy ideas on climate. More than 341,000 people worldwide, including over 130 members of Congress, have used the simulation.
This tool from the US Geological Survey tracks the production over over 90 minerals in 180 countries. For a selected country, you can see how many critical minerals it produces, where else those minerals are produced, and what each mineral is used for.
This massive interactive project includes over 2 million species known to humanity and you can see how every creature is related. Try different tree modes or search your favorite species.
The sheer enormity of the universe escapes our ability to conceive of its scale, despite the best efforts of human imagination. This interactive provides an intuitive sense of how small we are, from a single astronaut to the Milky Way and beyond.
Transformer architecture is the neural network framework upon which large language models predict and generate text based on user inputs. This interactive lets you explore the "thinking" a GPT does to generate responses based on your input.
The brain contains about 86 billion neurons—nervous system cells—and controls vital bodily functions via electrochemical signals. Neurons form circuits through axons, and different brain regions use these circuits to perform specific tasks.
CRISPR is a revolutionary gene-editing technology already making a real-world impact in helping to treat several diseases and conditions. This simulation provides a microscopic view to help easily visualize the complex science.
This 3D solar system visualization displays the positions of known asteroids, comets, and spacecraft involved in asteroid studies. Major asteroids include additional details, including orbital trajectories and discovery dates.
The ISS is the largest human-made object in space. Its modules were meticulously connected by robotic arms and astronauts during slow, careful spacewalks, creating a structure with over eight miles of electrical wire.
The map concisely describes many highly complex theories, from those involving quantum gravity and black holes to dark matter and energy. Supplementary resources, key questions, and possible solutions accompany each description.
