'Baby Grady' gives fertility hope to boys with cancer

Health
Scientists say they have made a significant leap towards helping boys with cancer stay fertile, thanks to a baby monkey called Grady.Cancer treatment can damage a boy's undeveloped testes and leaves a third of survivors infertile in adulthood. Baby Grady is the first primate born using frozen samples of testicles taken before her dad started puberty. Experts said the technique, detailed in the journal Science, could soon be used in the clinic.Chemotherapy and radiotherapy can destroy someone's ability to have children. Women and girls can have eggs or ovaries frozen in order to have children after their cancer therapy is over.Adult men can have a sperm sample frozen, but this is not an option for boys who have not gone through pu...

Scientists are watching this slow erosion very closely. They think they see the remnants of many such water-birthed islands on the Red Planet. If that is true, it is really intriguing. On Earth, we know that wherever you get submarine volcanic processes, you also very often get conditions that support microbial communities. What the researchers see occurring at Hunga Tonga Hunga Ha'apai (HTHH) therefore may be a kind of template to help them understa...
