The creaky noise known as vocal fry that people generally associate with young women – and some find irritating – is actually more common in men

An exotic new molecule is shaped like a butterfly, complete with "wings" made from electrons. The discovery could provide a gateway to completely new parts of the quantum realm

Previously classified photos and documents show the scientific work that went into the world's first atomic test in 1945 – a test that, just weeks later, would see nuclear bombs dropped in Japan

Gold is chemically inert and so doesn't tarnish, but exactly why had been a mystery

Researchers have designed a quantum version of a pendulum clock. It could shed light on timekeeping in the quantum realm

Even if you’ve never bought any cryptocurrency, like columnist Karmela Padavic-Callaghan, your money may be affected by Bitcoin’s fate – which is uncertain, as quantum computing advances are threatening to make the encryption protecting it useless

Quantum Backrooms is a horror game in which the player explores eerie rooms. The twist is that the rooms have been generated by a quantum computer

Particles of light cannot be divided into smaller particles, but if you try to snip off the end of one, instead of shortening it multiplies

Computer simulations have uncovered a new manganese compound that could exist deep in Earth’s mantle and may be connected to the process that gave our atmosphere oxygen

A quantum computer made from extremely cold atoms can correct its own errors during long computations, an important prerequisite for becoming truly useful
