Wood burners are a danger to children and elderly people and should be sold with a health warning, according to scientists behind a new study.
Researchers from the University of Sheffield placed pollution detectors in 19 homes for a month this year and collected data every few minutes.
Wood burners were lit for about four hours at a time and, while operating, the levels of harmful particles detected was three times greater than when they were unlit.
These particles have been linked to a number of health issues and can cause damage to the lungs - particularly in young and old people, the Guardian reported.
Coinbase, a cryptocurrency exchange that enables users to trade digital currencies such as Bitcoin, announced yesterday that it had filed with the SEC to become the first Bitcoin-focused company to list on the stock market. This is big news for technology and business, at a time when Bitcoin is trading at unprecedented (but extremely volatile) prices. But Coinbase is also at the front of another, more concerning, trend in tech – one which raises questions about the kind of future such companies are building. At a Coinbase all-staff meeting in June to discuss the company’s response to the unlawful killing of George Floyd and the worldwide protests against racism that followed, employees “walked out” (by closing their laptops) when CEO Brian Armstrong refused to say whether the company would publicly state that “black lives matter”. He later did so on his personal Twitter account, but in September he wrote a blog post in which he stated that company would not engage on
Timeline of the pitch drop experiment.
The experiment was not originally carried out under any special controlled atmospheric conditions, meaning that the viscosity could vary throughout the year with fluctuations in temperature. However, sometime after the seventh drop fell in 1988, air conditioning was added to the location where the experiment resided. The temperature stability has lengthened the interval between each drop.
The pitch drop experiment is recorded in the Guinness Book of Records as the world’s longest continuously running laboratory experiment, but it isn’t the only pitch drop experiment in the world. A pitch drop experiment was recently discovered at Aberystwyth University in Wales, that actually predates the famous Queensland experiment by 13 years. But the pitch used is stiffer and has never yielded a single drop.
But officials are still recommending Britons take the immune-boosting nutrient over the winter.
Health Secretary Matt Hancock ordered a rapid review into the vitamin s effect on Covid in October, after coming under fire for writing it off without any evidence to back his claims.
A panel of experts across multiple Government agencies, including Public Health England, analysed the best scientific studies from around the world, though they did not say which or how many papers they looked at.
But the team, led by NHS watchdog NICE, said it was not possible to determine a direct relationship between vitamin D and Covid, citing a lack of high-quality trials.

There is not enough evidence that vitamin D supplements protect people against Covid-19, an expert panel says.
Made up of the National Institute for Health and Care Excellence, Public Health England and the Scientific Advisory Committee on Nutrition, it said more research was needed.
But everyone is still advised to take a daily supplement this winter to keep bones and muscles healthy.
Free supplements are being offered to the most vulnerable in the UK.
However, they found there was insufficient evidence to recommend it for preventing or treating the disease.
