Across thousands of years of human history, people built monuments whose scale still inspires disbelief. They moved stones weighing tens of tons. They carved enormous figures into desert landscapes. They raised stepped temples above some of the world's earliest cities. They recorded visions of luminous beings, flying divine

Every living person may carry fragments of DNA inherited from an ancient human population that scientists have never identified from a sequenced fossil. A study published in Science on July 30, 2026, used a new computational method called TRACE to search modern human genomes for exceptionally ancient genetic lineages. The

Why does the universe make mathematical sense? That question sounds simple, but it reaches into some of the deepest unresolved issues in physics and philosophy. Gravity follows equations. Electromagnetic fields can be described mathematically. Quantum particles obey probability rules of astonishing precision. Mathematical ideas developed with no obvious connection to

Psychiatric diagnoses can appear strikingly different on the surface. Attention-deficit/hyperactivity disorder is associated with differences in attention, impulsivity and activity regulation. Anorexia nervosa involves restrictive eating, intense fear of weight gain and disturbances in body image. Schizophrenia can alter perception and thinking, while depression is often dominated by

Look at everything around you. Your body, the ground beneath your feet, every ocean on Earth, every planet in the Solar System, the Sun, the Milky Way, and every glowing galaxy photographed by our most powerful telescopes are made from the same broad category of material: ordinary matter. Yet ordinary

A highly unusual gravitational-wave signal has raised an extraordinary possibility: scientists may have detected a black hole unlike any known object produced by a dying star. The candidate event, designated S251112cm, was recorded on November 12, 2025, by the international network of gravitational-wave observatories associated with LIGO, Virgo,

What happens when every basic need is met? No predators. Unlimited food and water. Safe housing. Perfect sanitation. It sounds like the blueprint for an ideal society. Yet one of the most famous behavioral experiments in modern science produced an outcome that continues to fascinate psychologists, sociologists, urban planners, and

Climate data is not just information on a screen. It helps cities prepare for floods. It helps farmers understand drought. It helps journalists explain extreme heat. It helps teachers educate students. It helps businesses evaluate risk. It helps emergency planners prepare for storms, fires, and sea-level rise. It helps

For years, one of the most fascinating questions in modern science and philosophy has sounded like something from science fiction: are we living inside a computer simulation? The idea is simple to imagine. If future civilizations became advanced enough, perhaps they could build a computer powerful enough to simulate an

Few questions in science are as fascinating, controversial, and deeply personal as the question of consciousness. Every moment of our lives is defined by conscious experience. We see colors, hear music, feel emotions, remember the past, imagine the future, and experience a sense of self moving through the world. Yet
History
One of the most haunting facts in modern history is also one of the most scientifically astonishing: the bomb dropped on Hiroshima released its destructive energy from the conversion of less than a gram of matter into energy. The weapon, known as Little Boy, detonated over Hiroshima on August 6,

There are certain scientific comparisons that do more than inform. They rearrange the way we feel about existence. One of them is this: a genome-length DNA molecule contains atoms on roughly the same order of magnitude as the number of stars in a typical galaxy. It is not a
