Scientists from around the globe are meeting in Britain to consider a proposal that could eventually see Greenwich Mean Time relegated to a footnote in history. For more than 120 years Greenwich Mean Time – GMT – has been the international standard for timekeeping, but it is now under threat from a new definition of time itself based not on the rotation of the Earth, but on atomic clocks. In January 2012 the International Telecommunication Union will meet in Geneva to vote on whether to adopt the new measure, despite protests from Britain.
The two-day meeting of about 50 experts at a country house north-west of London, under the aegis of the prestigious Royal Society, on Thursday and Friday will look at some of the issues involved. Predictably the question has hurt Britain’s national pride – particularly when the British believe their old rivals France are leading the push to change from GMT to the new time standard.

There is new evidence that the sun’s UV rays are even more damaging than previously thought.
The sun emits two kinds of UV rays to the earth’s surface: UVA and UVB. It had been thought that those rays do not damage the deeper layers of the skin as much as they damage the top layers. New research from Kings College London has found that is the case for UVB rays, but not for UVA rays. The study has found UVA rays are more carcinogenic than previously realised – a finding scientists say underscores how important it is to limit exposure to the sun and to tanning studios. The study was led by Antony Young, Professor of experimental photobiology at King’s College. Read the full article »»»»
