Compound vital for all life likely played a role in life's origin
Compound vital for all life likely played a role in life’s origin
A chemical compound essential to all living things has been synthesised in a lab in conditions that could have occurred on early Earth, suggesting it played a role at the outset of life, finds a new study led by UCL researchers. The compound, pantetheine, is the active fragment of Coenzyme A. It is important for metabolism - the chemical processes that maintain life.

Vast amounts of waste caused by single-use e-cigarette batteries
Vast amounts of waste caused by single-use e-cigarette batteries
While the lithium-ion batteries in disposable electronic cigarettes are discarded after a single use, they can continue to perform at high capacity for hundreds of cycles, according to new research from UCL and the University of Oxford, supported by The Faraday Institution. The study, published in Joule , highlights a growing environmental threat from these increasingly popular vape pens, which are not designed to be recharged.

’Bouncing’ comets could deliver building blocks for life to exoplanets
How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers from the University of Cambridge have shown how comets could deposit similar building blocks to other planets in the galaxy. It's possible that the molecules that led to life on Earth came from comets, so the same could be true for planets elsewhere in the galaxy Richard Anslow In order to deliver organic material, comets need to be travelling relatively slowly - at speeds below 15 kilometres per second.

What Guy Fawkes can teach us about the sky at night
With bonfire night on the horizon, scientists reveal just why fireworks are differently coloured and what this can teach us about stars in space. Elements commonly found in salts are used to make the colours in fireworks. The colours are caused when the elements are heated, causing them to release light in different colours, from bright blues to deep reds.
