Carbon atom is Earth’s ultimate wildcard — four arms that can link into chains, rings, spirals; this simple flexibility has built proteins, cells, neurons, and the entire…
Think of carbon as the Lego block of life—but a block with four mighty connectors instead of two. That means it can build straight lines, loops, ladders, or…
Discover moreMicrobes choreograph existence—gut bacteria sway mood, soil bacteria grow food, ocean microbes exhale oxygen; invisible armies maintain our fragile reality, reminding us the…
Imagine a world sustained not by towering forests or swirling storms, but by little beings too small to see with your eyes. Microbes are the undercover…

Strange materials exist that conduct electricity only when chilled near absolute zero degrees
Each superconductor has its own temperature threshold. Below it, electrical resistance vanishes and magnetic fields are expelled; that expulsion can make a…

Earthquakes send shockwaves faster than fighter jets
An earthquake can send its first signal through rock faster than a fighter jet can fly. The waves that do much of the shaking move more slowly, so sensors may…

The mutation that let adults digest milk
Most people make less lactase after childhood. This enzyme breaks milk sugar, lactose, into pieces the gut can absorb; in some populations, genetic variants…

Some stars spin so fast they fling matter into space
Gravity holds a star together, but rotation gives gas at its equator an outward nudge. For some fast-spinning stars, that nudge lets material move into a disk…

Water can behave like two liquids at once
Under extreme cold and pressure, water can sort itself into two liquid phases. Their molecules arrange differently, giving the liquids different densities,…

A tiny mistake in protein folding can cause disease
A protein has to fold into the right shape to do its job, much like a tool needs the right parts in the right places. A small folding error can leave it…

What if time is only a side effect of reality
The idea is that time might not be a separate backdrop that the universe moves through. Instead, it could arise from how events change in relation to one…

What Earth’s craters reveal about cosmic impacts
A crater records an impact, but Earth slowly rubs out the evidence. Wind and water wear the rim down, sediment buries it, and moving crust can hide it…

Some chemical mixtures can change color in repeating waves
In an oscillating reaction, processes feed and inhibit one another, repeatedly changing which chemicals dominate. A visible indicator turns those shifts into…

Donated thymus tissue can give children an immune training ground
The FDA approved Rethymic in 2021 for children born without a thymus. Processed donor tissue provides an environment where the body's T cells can develop.…

Atoms that exist for less than a blink
To make a superheavy atom, researchers smash nuclei together and look for signs that they briefly fused. The atom may vanish almost immediately, but its decay…
Discover moreNuclear physics gave us both starlight and mushroom clouds: the same equations behind warmth of suns and destruction of cities.
The same secret that keeps stars blazing also lurks inside the most terrifying weapons humans have ever built. Nuclear energy is both cradle and scythe,…

The hidden patterns mathematicians see in prime numbers
Imagine publishing the result of multiplying two enormous prime numbers while keeping the primes themselves secret. Anyone can use the public number to help…

NASA hit an asteroid moon and shortened its orbit by 33 minutes
DART struck Dimorphos in 2022 to test whether an impact could redirect an asteroid. The moonlet then completed its circuit around Didymos faster than before.…

Chemists are turning plastic waste into fuel
Some plastic can be heated without oxygen, breaking its long molecules into smaller compounds. Those pieces can then be separated and refined into fuel, much…

Hot Jupiters lose gas as their atmospheres expand
A giant planet’s orbit shrinks to days when it hugs its star. But the close pass comes with a cost: radiation heats the atmosphere until it expands, making it…

Asteroid Bennu carried ingredients used by life
Laboratory analyses of returned Bennu material identified amino acids and the five nucleobases used in DNA and RNA. These are chemical building blocks, not…

Lightning can make new chemicals from the air
Lightning’s heat gives nitrogen and oxygen in the air enough energy to react. The new compounds wash down in rain as nitrates, a form plants can use. A storm…

Volcanoes can sing before they erupt
As gas and bubbles squeeze through cracks in molten rock, they make rumbles and vibrations that instruments can pick up. If the sounds change, scientists may…

One jellyfish can reverse part of its life cycle
Turritopsis dohrnii can transform from its adult medusa stage back toward a juvenile polyp under certain conditions. Instead of only producing a new…

A curved wall can carry a whisper across a room.
A curved wall can carry a whisper across a room. In a whispering gallery, sound can follow the curved boundary through repeated reflections, reaching a…

Every time you touch a doorknob and feel a spark, you’ve briefly created lightning in miniature.
Every time you touch a doorknob and feel a spark, you’ve briefly created lightning in miniature. You build up electric charge, then it leaps through the air…
