Cambridge University scientists say they have seen four-stranded DNA at work in human cells for the first time.
The famous “molecule of life”, which carries our genetic code, is more familiar to us as a double helix.
But researchers tell the journal Nature Chemistry that the “quadruple helix” is also present in our cells, and in ways that might possibly relate to cancer.
They suggest that control of the structures could provide novel ways to fight the disease.

Black carbon, or soot, is making a much larger contribution to global warming than previously recognized, according to research.
Scientists say that particles from diesel engines and wood burning could be having twice as much warming effect as assessed in past estimates.
They say it ranks second only to carbon dioxide as the most important climate-warming agent.
The research is in the Journal of Geophysical Research-Atmospheres.

An international team of scientists has generated the first laser-like beams of X-rays from a tabletop device.
Most of today’s X-ray lasers require so much power they rely on facilities the size of sports stadiums.
This has prompted efforts to build a cost-effective and reasonably sized X-ray laser.

Researchers have succeeded in taking a stunning image of a newly synthesised molecule called olympicene.
The molecule – just over a billionth of a metre across – gets its name because its five linked rings resemble the Olympic symbol.
It was first made by collaborators at the University of Warwick in the UK.
.
The technique showcases details well under a billionth of a metre in size

Rural communities across Africa may soon benefit from improved water supplies thanks to mobile phone technology.
UK researchers have developed data transmitters that fit inside hand pumps and send text messages if the devices break down.

Nasa’s new Mars rover has returned its first 360-degree colour panorama from the surface of the Red Planet. The Curiosity robot used its wideangle science camera placed high up on a mast to acquire the frames.
The low-resolution vista shows at centre the big mountain that lies in the middle of Gale Crater, the deep depression in which the rover landed.

Many bird species are unaffected by wind farms, concludes a study carried out by UK bird charities.
Scientists with the British Trust for Ornithology (BTO) and RSPB found that building the turbines was more disruptive than operating them.

The US has regained top spot from China as the biggest investor in clean energy in 2011, according to global rankings.
The table, published in a report by the Pew Charitable Trusts, showed that US invested more than $48bn (£30bn) in the sector, up from $34bn in 2010.

Renewables can be one of the cheapest forms of energy within years, Prime Minister David Cameron has said. But they need to become economically self-sustaining, truly global, and must receive continued research support.
