But the brain is not a magical black box inside your head. It is an organ, just like the heart or lungs, made up of cells and supplied with … Read More

23 and NZ: Genetic testing results restricted - The Dismal Science

Eric Crampton Sep 06, 2016

I knew that genetic testing service 23andMe was having FDA trouble in the US: the FDA restricted 23andMe from providing health advice based on its genetic tests except where the FDA approved the specific tests. As Gizmodo put it, you’re getting less service for more money, but with an FDA seal of approval on those tests you … Read More

Ice ages led to ‘explosive’ diversity in Kiwi species - News

John Kerr Sep 01, 2016

Ancient walls of ice separating kiwi populations have left their mark in the DNA of New Zealand’s most iconic species. A new study published this week in PNAS has revealed the enormous impact historic cold snaps had on the evolution of kiwis. Researchers based in Canada, in collaboration with Department of Conservation scientists, examined a database of kiwi DNA across the geographic … Read More

Can genes really predict educational achievement? - Guest Work

Guest Work Jul 27, 2016

Daphne Martschenko, University of Cambridge Researchers at King’s College London say they are able to predict educational achievement from DNA alone. Using a new type of analysis called a “genome-wide polygenic score”, or GPS, they analysed DNA samples from 3,497 people in the ongoing Twins Early Development Study. They found that people whose DNA had … Read More

The Earth’s biodiversity could be much greater than we thought - Guest Work
