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.
Whilst any effective discouragement to the ingestion of sugary beverages would likely have a health benefit on society, taxation of specific foods is likely to be currently politically undeliverable in most democracies.
A workable alternative might be to encourage the major companies to switch to the aggressive promotion and marketing of less harmful versions of their products.
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.
Younger adults and children consume much greater quantities of sugary drinks.
This is a concern for their health, not only in terms of diabetes and obesity, but also tooth decay.
Our work suggests that a sugary drinks tax would have a much greater impact in terms of reducing obesity in younger adults.
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 .
Oxford University is getting part of £35million grant to develop new technologies for research into cancer.
With the funding, the university will be a centre for cancer imaging. It's hoped the new technology will help experts understand how the disease develops in the body.
We are all programmed to recognise faces and download vital information about a person's identity, gender and personality. But we all make mistakes. Now new research at the Universities of Surrey and Oxford is making face recognition by computer deadly accurate.
In fact, their work is becoming an important tool in the hunt for terrorists and criminals. Fred joined PhD student Paul Koppen for a photo session.
A survey shows students at Oxford University enjoy a good quality of life. The university is in the top five English institutions in the category. The survey also shows graduates' earning power is among the best.
A new drug has been approved by the European Medicines Agency which could offer better treatment to patients with multiple sclerosis. Alemtuzumab will give people who have the disease the chance to live without the side effects for much longer.
Symptoms of the disease can include loss of physical skills, sensation, vision and bladder control.
Professor Herman Waldmann was involved in the early discovery work of the antibody drug called Campath-1H at Cambridge University. It was originally used to treat leukaemia. He continued to study the drug for two decades while at Oxford University.
The university have launched a new animation to replicate a MRI scan and how our brain works.
Dr Stuart Clare of Oxford University, lead scientific advisor on the animation, said:
‘The animation beautifully shows what is going on inside the body during an FMRI scan, right down to the atomic level, and how the very strong magnet at the core of the machine gives us incredible detail on brain function.
‘Ruby Wax has a real interest in the neuroscience of mental health, something that we are researching here in Oxford, and we were delighted that she agreed to voice the animation.’
Oxford University have launched a new animation to look at our brain and how we move and talk.
The video is the latest from the web portal which gives people access to some of the exciting science happening at the university.
Ruby Wax narrates the animation where a Magnetic Resonance Kmaging (MRI) scanner sees inside our brains and detects surges of oxygenated blood to how we move.
Dr Stuart Clare of Oxford University, lead scientific advisor on the animation, said: ‘Functional MRI is revolutionising our understanding of the brain. As long as someone can do something lying down then we can scan their brain and discover the activity behind the action."
"As technology improves and magnet strength increases, we can determine finer detail about brain activity related to particular tasks or behaviours. This isn't just about finding out how our brains work, but also how they respond to damage or treatment.
One in three children and young people are overweight or obese according to a new study from Oxford University and the British Heart Foundation.
The researchers said that children who skip meals, drink too many fizzy drinks and watch too much television are storing up future health problems including diabetes and heart disease.
