Rising skin cancer rates are more likely to affect wealthy people, says 12-year review

...ncrease in incidences of skin cancer, coupled with ageing populations, will place greater demands on dermatology and other related specialties over the coming years. “The number of people aged 60 and over is set to rise by more than a half by 2030 and 80 per cent of all skin cancers occur in this age gro...

Bioluminescence at the service of a novel cerebral imaging technique

... Drosophila is an excellent model for the study of ageing and longevity, because it has recently been shown that flies endowed with a mutation of the insulin receptor live much longer. It is also possible to exploit the powerful genetic tools of the Drosphila to study and compare these maps in flies bearin...

Vaccination with embryonic stem cells prevents lung cancer in mice

...ne would be a big victory). We may also vaccinate ageing rodents, the majority of which develop endocrine tumours in old age. "In terms of human testing, if all goes well, then I think this vaccination might best be tested in women at high (genetic) risk of breast cancer, in people with high (genetic) r...

New research shows big improvement in survival after stroke

...of strokes occurring is expected to rise, with the ageing of the population and improved survival. In three separate studies between 1981 and 2003, researchers investigated the rate of short and medium-term survival after stroke and found that the probability of survival increased from 1981, especially i...
