Exposure to sun poses risk of skin cancer even in the dark, study finds

Guardian Science - Thu, 2015-02-19 19:00

Moving immediately into the shade does not stop sun damage as UV rays can continue damaging skin cells hours after exposure

Damage to skin cells continues for hours after spending time in the sun, according to research that uncovers a new link between sun exposure and cancer.

The discovery that some of the most serious damage to skin cells may be occurring in the dark raises the prospect of new “evening after” lotions that would help limit the effect and reduce the risk of skin cancer.

Women have been oversold HRT for decades

Guardian Science - Thu, 2015-02-19 14:52
High-quality studies, rather than drugs companies, are finally driving menopause treatment – but there’s a lot of ground to make up

On my desk I keep a copy of Feminine Forever, a book promoting hormone replacement therapy (HRT), published in 1966, by Robert A Wilson. On the front, it proclaims that it is “a fully documented discussion of one of medicine’s most revolutionary breakthroughs – the discovery that the menopause is a hormone deficiency disease, curable and totally preventable and that every woman, no matter what her age, can safely live a fully sexed life for her entire life”.

I keep this book to remind me of a few things. One, that it is possible to be very, dramatically wrong in medicine – especially when you are very sure of yourself. Two, that when you make big promises, you should have robust, unbiased and powerful data to support them. Three, that when medicine tries to suggest that a new large section of the population – on this occasion, that all women over menopausal age – are “diseased”, one had better look to see who is behind that claim, and why. And last, hype around new medical products are, sadly, nothing new.

Why I want to be a passenger on Mars One

Guardian Science - Thu, 2015-02-19 13:01

Hannah Earnshaw explains why she wants to be part of the mission to colonise the red planet

I have always been in awe of the night sky, trying to comprehend the vastness of space and the countless wonders it contains. But I have always felt a certain dissatisfaction with only being able to see it at a distance.

One day I imagine that humanity will be able to visit other planets in the solar system, and venture even further to other stars, but this has always seemed very far away. That’s the reason why I applied for the Mars One mission, aimed at starting a human colony on Mars – it seemed like a real opportunity to get closer to the rest of the night sky, to give me a chance to be a part of taking humanity into the stars.
