Solution to 50-year-old mystery could lead to gene therapy for common blood disorders - News

Jean Balchin Apr 06, 2018

In a recent study published in the journal Nature Genetics, UNSW Sydney-led researchers have used CRISPR-gene editing to introduce beneficial natural mutations into blood cells to boost their production of foetal haemoglobin. This study solves a 50-year-old mystery about how these mutations operate and alter the expression of human genes. Naturally carried by a small percentage of people, these mutations contribute to … Read More

Dogs, Diets and the Impact of Evolution - BioBlog

Alison Campbell Feb 05, 2018

Yvonne d’Entremont (aka SciBabe) recently posted an article on ‘alternative’ foods and health products for pets, in her usual no-holds-barred style. It’s always good to see pseudoscience called out for what it is, and in the case of pet-focused quackery it’s a message that needs multiple repeats. Why? Because pets are dependent on us, & we have a responsibility … Read More

Axolotl and flatworm genetic codes help solve regeneration riddle - News

Jean Balchin Jan 26, 2018

When I was fourteen years old, I arrived home from school one day to find a large glass tank on my bedside table. Inside this tank was a curious creature, pale pink in colour, just floating there and eyeballing me through the glass. I instantly felt rather uncomfortable. What was this strange animal? Was it an alien? Why was … Read More

Gene drives could wipe out island pest populations – study - News

John Kerr Aug 10, 2017

An entire island population of invasive mice could be eradicated by the single release of 100 engineered mice carrying ‘gene drives’ which spread infertility throughout a population. The finding comes from a new study which used computer simulations to investigate how gene drives – essentially sets of ‘selfish genes’ which are more likely to pass on to the next … Read More

Victoria Metcalf Apr 08, 2014

Four of the Antarctic or anything else headlines/social media bits that have grabbed my attention this week. A double fracture in my daughter’s wrist followed by two mystery allergic reactions and a stomach bug for all means it’s a little past Friday, but we’ll just have to roll with it and temporarily suspend belief. Don’t do that with the science … Read More
