Consumer products’ air quality impact ‘underestimated’

Image copyright Getty Images US research has found that chemicals in everyday household products are now a key contributor to city air pollution, rivalling some vehicle emissions. The study, led from Colorado University, focussed on so-called volatile organic compounds (VOCs). These are contained in petroleum-based products such as cleaning fluids and paints, and when they […]

Scientists based in Wales have shown that excessive amounts of nitrogen present in sewage and livestock waste is finding its way […]

‘100,000 orangutans’ killed in 16 years

Image copyright Serge Wich Image caption Bornean orangutans’ forest habitat is changing at an “unsustainable rate” More than 100,000 Critically Endangered orangutans have been killed in Borneo since 1999, research has revealed. Scientists who carried out a 16-year survey on the island described the figure as “mind-boggling”. Deforestation, driven by logging, oil palm, mining and […]

UK air pollutants continue decline

Image copyright Getty Images Total emissions from motor vehicles fell 12% from 2012 to 2016, according to the Office for National Statistics. However, the UK remains in breach of European limits for nitrogen oxides (NOx) in 16 cities. Nonetheless, environmentalists have welcomed the overall drop in pollutants from cars and lorries. The reduction is thought […]

Probe provides rapid lung investigation

Media captionScientists have developed a lung probe that finds infections Scientists have developed a probe that for the first time goes inside the lung to find bacterial infections. Currently, this is done by sending samples to a laboratory and waiting several days for the results. The new approach was inspired by the 1960s film Fantastic […]

Quantum computers ‘one step closer’

Image copyright Science Photo Library Quantum computing has taken a step forward with the development of a programmable quantum processor made with silicon. The team used microwave energy to align two electron particles suspended in silicon, then used them to perform a set of test calculations. By using silicon, the scientists hope that quantum computers […]

Crypto-currency craze ‘hinders search for alien life’

Image copyright Getty Images Image caption If there is intelligent life out there, it might be broadcasting signals across the universe Scientists listening out for broadcasts by extra-terrestrials are struggling to get the computer hardware they need, thanks to the crypto-currency mining craze, a radio-astronomer has said. Seti (Search for Extraterrestrial Intelligence) researchers want to […]

Musk’s Tesla to stay in space for millions of years

Image copyright SpaceX / AFP Image caption The Tesla’s paint job will suffer as it’s peppered by micrometeorites over time The Tesla car that Elon Musk launched into space is likely to stay there for tens of millions of years before crashing into the Earth or Venus. That’s the conclusion of an analysis by Czech […]

Genes remain active after death

Image copyright PETER MENZEL/SCIENCE PHOTO LIBRARY Image caption Transcriptomics might one day help forensic scientists predict time of death Cells continue to function even after an individual dies. That’s according to a scientific study published in Nature Communications. Analysing post-mortem samples, an international team of scientists showed that some genes became more active after death.
