Genetics

Researchers at the University of Cambridge have identified a bunch of genes linked to obesity in dogs – and found the very same ones in humans predisposed to putting on weight too.

Researchers have taken the best genetic characteristics of the Fraser fir, arguably the most popular choice for Christmas tree, and used them to create a tree that’s taller, prettier, and – importantly – sheds only a fraction of its needles.

For the first time, scientists have successfully produced full-length spider silk fibers using genetically modified silkworms. This silk has the potential to provide a scalable, sustainable and better-quality alternative to current synthetic fibers.

Often, the decision to get a Rottweiler over a Chihuahua is made based on personality. A new study has found that while the breed is an important factor, a dog’s personality is determined by a complex interaction between genetics and environment.

Zoltan Istvan is a transhumanist, journalist, politician, writer and libertarian. We caught up with Istvan to chat about how transhumanist ideals can translate into politics, how technology is going to change us as humans and the dangers in not keeping up with new innovations.​

With the calender having rolled over into another year, it's an ideal time to take a look back at some of the most significant and far-reaching breakthroughs that we saw during 2011.
