Why isn’t there a gene for depression? - Guest Work

Guest Author Sep 14, 2016

Sarah Bailey, University of Bath Depression is sometimes categorised as a mental, rather than a physical illness – as though somehow mental health is different from physical health. 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 Author 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

Samoa obesity-gene link not so simple - News

John Kerr Jul 26, 2016

High rates of obesity in Samoa have been linked to a particular version of a gene which is prevalent among the island’s population. However, relying on the often repeated formula of ‘gene X’ causes ‘condition Y’ risks oversimplification, say experts. The results, published today in Nature Genetics, were based on an analysis of DNA samples and basic health data collected from … Read More

Twins and genetic performance - The Dismal Science

Eric Crampton Feb 26, 2016

Identical twins have school test scores that are more closely correlated than scores from fraternal twins. de Zeeuw et al look at data from the Netherlands Twin Register. Even children attending the same primary school and taught by the same teacher differ greatly in their performance. In the Netherlands, performance at the end of primary school determines the enrollment … Read More
