Sun exposure is a major contributing factor for melanoma skin cancer, the fifth most common cancer in the UK, with more than 14,000 people diagnosed each year. A recent research suggests sunscreen alone should not be relied on to prevent malignant melanoma, a deadly form of skin cancer.
In the new study, scientists at the University of Manchester looked at the effects of UV light on the skin of mice at risk of melanoma. This allowed them to examine the effects of sunscreen in blocking the disease. “UV light targets the very genes protecting us from its own damaging effects, showing how dangerous this cancer-causing agent is,” said lead researcher Prof Richard Marais. Very importantly, this study provides proof that sunscreen doesn’t offer complete protection from the damaging effects of UV light. This work highlights the importance of combining sunscreen with other strategies to protect our skin, including wearing hats and loose fitting clothing, and seeking shade when the sun is at its strongest.

Destinations compete for the attention of would-be travelers everywhere: on billboards, in newspaper supplements, via online advertisements ― even in cinema.
In the world of travel industry product placement, few boons are better than having a movie shot on location. And no country knows this better than New Zealand, where the huge success of the Lord of the Rings franchise helped turn the country into one of the world’s most sought after travel destinations.
According to a survey taken after all three movies had been released, 6% of New Zealand visitors said the franchise was one of their main reasons for visiting the country. After the first film of The Hobbit trilogy was released in 2012, the New Zealand tourist board rebranded the entire country as “Middle-earth”. From January to September 2013, international visitor numbers were up nearly 10% ― with 8.3% of international visitors overall citing The Hobbit as their draw. (That means The Hobbit’s influence was about the same as “getting a good deal on flights”, which was the reason another 8.8% of foreign visitors gave).
