Researchers in the Department of Meterology believe they have discovered new evidence to suggest lightning is triggered not only by cosmic rays from space, as has previously been thought, but also by energetic particles from the Sun.
The Berkshire scientists found a link between increased thunderstorm activity and streams of high-energy particles accelerated by the solar wind, suggesting that particles from space help trigger lightning bolts.
After the arrival of a solar wind at the Earth, the researchers showed there was an average of 422 lightning strikes across the UK in the following 40 days, compared to an average of 321 lightning strikes in the 40 days prior the arrival of the solar wind.
The rate of lightning strikes peaked between 12 and 18 days after the arrival of the solar wind.
New research has been published about the effects of taxing soft drinks with the aim of reducing obesity rates. We speak to Jon Griffin from Kent Scientific Services, Adam Briggs from Oxford University and Gavin Partington of the British Soft Drinks Association
Health experts who have called for a 20% tax on sugary soft drinks say the move could raise more than £275 million each year for the treasury - around 8 pence per person, per week.
This saving "could be used to increase NHS funding during a period of budget restrictions or to subsidise foods with health benefits, such as fruit and vegetables," researchers from Oxford and Reading universities said.
Calls for a 20% tax hike on fizzy drinks have been met with skepticism by Cambridge University clinical biochemistry and medicine professor Sir Stephen O'Rahilly.
Doctors who have called on the Government to introduce a 20% tax on sugary drinks say 16 to 29-year-olds consume the most sugary drinks - an average of 300ml per day, compared to 60ml among those aged over 50.
A 20% tax on sugary drinks would cut the number of overweight people in the UK by 285,000 over 10 years, according to experts from Oxford and Reading universities.
A tax on the drinks, which the researchers say are linked to "ill health" and have "no beneficial nutrients", could reduce cut the number of people who are obese by 180,000 alone, according to the findings printed in British Medical Journal .
Reading University is investing £50 million in 50 new academics to further knowledge in research areas of critical global importance. The university makes £200m a year and and generates three times that for the regional economy.
