The digital world will always entail risks for teens, but that doesn’t mean parents aren’t without recourse.
Rows of identical Earth-like planets stretch out into the vast copy multiverse, with a dark starry background visible between them.
Within our observable Universe, there's only one Earth and one "you." But in a vast multiverse, so much more becomes possible.
A stylized digital shield in the center, surrounded by red pixelated designs, with quantum code fragments displayed on the shield. The background has black, swirling patterns, reminiscent of encryption tools at work.
Quantum computing brings significant opportunities — but equally significant cybersecurity risks.
A technician in a cleanroom suit works by a large cylindrical piece of equipment in a high-tech laboratory setting with industrial tools and machinery.
A recent experiment challenges the leading dark matter theory and hints at new directions for uncovering one of the Universe's biggest mysteries.

Most fundamental constants could be a little larger or smaller, and our Universe would still be similar. But not the mass of the electron.
Image of Mimas, one of Saturn's moons, partially illuminated. The large Herschel crater is prominently visible on the right side of the moon's surface.
The existence of another watery world in the outer solar system may offer clues to how such seas form — and hope for another spot to search for life.
A collage features a tennis player and a basketball player against a backdrop of financial charts, graphs, and mathematical equations on a checkered pattern.
How Daniel Kahneman and Amos Tversky cracked open behavioral economics and enlightened all our choices.
Two breathtaking pictures of a galaxy and a star taken by the Hubble telescope, highlighting the beauty and cosmic magnitude that fuels the Hubble tension.
In the expanding Universe, different ways of measuring its rate give incompatible answers. Nobel Laureate Adam Riess explains what it means.
A black-and-white portrait of a man with curly hair, glasses, and a beard is centered against a green and blue background with abstract DNA helix patterns, representing leadership essentials.

From nothing to everything: How zero changed our understanding of the universe, forever.
The image shows a bright spot labeled "JADES-GS-z13-1-LA," seemingly an impossible light captured by the JWST, surrounded by measurement markers, including a scale bar for 1 kpc and 0.28 arcsec. Filters and colors are listed at the bottom.
The Lyman-α emission line has never been seen earlier than 550 million years after the Big Bang. So why does JADES-GS-z13-1-LA have one?
A detailed image of two galaxies in space, one with spiral arms on the left and the other, more elliptical, on the right, surrounded by distant stars.
Galactic activity doesn't just arrive when supermassive black holes feast on matter. Before, during, and after all create fascinating signs.

Finding life beyond our Solar System requires understanding its host planet.
A graph depicting projectile motion with displacement on the vertical axis and time on the horizontal axis. The projectile's trajectory forms a perfect parabola, with initial velocity u and angle θ clearly indicated.
Taught in every introductory physics class for centuries, the parabola is only an imperfect approximation for the true path of a projectile.
A world map displays global climate zones with colors representing varying levels of temperature and precipitation: green for temperate, yellow for arid, orange and red for hotter regions, and blue for wet zones.
The salinity of the oceans is not just a matter of taste. Saltier water behaves differently, too.
