Using a 3-D petri dish, Researchers at Brown University and Women & Infants Hospital of Rhode Island have built a completely functional artificial human ovary that will allow doctors to harvest immature human egg cells (oocytes) and grow them into mature, ready-to-be-fertilized human eggs outside the body. (In vitro) The advance could eventually help preserve fertility for women facing chemotherapy or other medical treatments that may be destructive to ovarian folliculogenesis. Press Release.

Interesting developments in med-tech: gene testing machines for doctors, a plan to engineer stem cells to kill HIV, a new way to repair damaged nerves, the next generation of retinal implants, and the first bionic fingers up for sale.

Scientists Repurpose Adult Cells - "Scientists have transformed one type of fully developed adult cell directly into another inside a living animal, a startling advance that could lead to cures for a variety of illnesses and sidestep the political and ethical quagmires associated with embryonic stem cell research."

This breaking story brings a new aspect to a complex debate. Reasearchers in a private clinic in the US have created human embryos specifically for the purpose of extracting stem cells. This seems a good platform on which to discuss the wider issue of the interaction between public/private research funding, technology and life. Here's hoping it won't just end up a pro-life/pro-choice bloodbath.
