A new paper challenges the thinking that sound cannot be heard in space. Physicists have demonstrated that there are situations when sound can be transmitted across a vacuum.

The illustration shows two piezoelectric solids 1, 2 that are separated by a vacuum gap of width d, and an incoming acoustic wave from solid 1 that tunnels across the vacuum gap into solid 2.

Is it actually possible for someone to hear you scream in space?

New research challenges the thinking that sound cannot be heard in space, by demonstrating situations when sound can be transmitted in a vacuum.

Maybe you can hear sounds in space after all

Air quality stations are accidentally gathering DNA, and this could be a potential 'game-changer' in the fight against global biodiversity decline.

Asian hornet (Vespa velutina), also known as the yellow-legged hornet or Asian predatory wasp, is a species of hornet indigenous to Southeast Asia. It is of concern as an invasive species in European countries like the UK, France or Spain.

Operational delays are increasingly common during heatwaves.

When is it too hot to fly?

Hot weather makes the air less dense, reducing aircraft engine and wing performance, which makes it harder for planes to take off and fly.
