Seconds after the Big Bang, the newborn universe gave rise to the first elements—ionized forms of hydrogen and helium. These particles combined, forging helium hydride—the first ever molecule. It ...

About 13.8 billion years ago, the newborn universe was a blazing sea of energy and particles. Within minutes of the Big Bang, conditions had cooled enough for the very first atoms—mostly hydrogen, ...

One of my closest friends is a neuroscientist, investigating how brain cells develop and how they search for and choose other brain cells to connect with. Her research can sound intimidating, but when ...

Assembly Theory is a way to understand how the complexity of life emerged through a mechanism of “self-assembly.” It could explain how life formed on Earth—or other planets—via the shortest path to ...

A University of Colorado Denver engineer is on the cusp of giving scientists a new tool that can help them turn sci-fi into reality. Imagine a safe gamma ray laser that could eradicate cancer cells ...

As mysterious as the Big Bang that gave birth to the universe is the brief but tumultuous period that immediately followed it. How did the cosmos transform from a uniform sea of darkness into a ...

Scientists at Rutgers and collaborators have traced the invisible dark matter scaffolding of the universe using over 100,000 Lyman-alpha emitting galaxies. By studying how these galaxies clustered ...

Only a fraction of the size of the Milky Way, these galaxies have thus far been too faint for most telescopes to spot. Among the hundreds of billions of galaxies that stretch across the known universe ...

In 1980, an ice climbing accident left one man dead - but what he saw changed his life forever. This video shares his ...
