Guardian Science - Wed, 2015-03-25 00:37

Owners of Highland Wildlife Park hope Victoria, 18, will get chummy with male Arktos during her stay in the Cairngorms

World's leading zoo association accused of overlooking horrific cruelty

Guardian Science - Tue, 2015-03-24 19:19

Zoos belonging to World Association of Zoos and Aquariums filmed allowing shocking mistreatment of elephants, dolphins, lions, bears, penguins and whales

Dozens of examples of harrowing cruelty towards animals in zoos have been overlooked by the world’s top zoo organisation, animal welfare groups have alleged.

Zoos belonging to the World Association of Zoos and Aquariums (Waza) have been filmed over the past five years making animals perform dangerous tricks, confining them to inadequate premises and beating them, contrary to Waza’s code of ethics, which demands the “highest standard of animal welfare”.

Angelina Jolie and ovarian cancer: the facts about screening and surgery

Guardian Science - Tue, 2015-03-24 18:38

Faced with unreliable screening, many women with a high lifetime risk of cancer opt for preventative surgery, just as Jolie did. But the timing can be crucial

As an A-list Hollywood film-maker, Jolie has few financial constraints on her medical care. Yet, the medical choice she was presented with and the trajectory of her treatment will be familiar to many women treated in NHS clinics. In Britain, those with at least two first-degree relatives who have had breast or ovarian cancer are eligible for genetic screening. Mutations in the BRCA1 and BRCA2 genes affect only about one in 500 women, but have a dramatic impact on the risk of developing ovarian cancer.
