The Y Chromosome is Here to Stay with Stable Genes: Men are Not Disappearing

The male chromosome in humans, the Y chromosome, has had a history of dramatic genetic decay. Despite this, though, it's managed to preserve a small set of genes. Now, researchers have found that these genes ensure not only the chromosome's survival, but also the survival of men in general.

Mutation in Dairy Cattle Increases Milk Yield, But Kills Embryos

Scientists have made an important discovery in dairy cattle. They've found a mutation that has a positive effect on milk yield, but causes embryonic death in dairy cattle. The findings could help explain a dilemma in dairy cattle breeding--the negative correlation between fertility and milk producti...

Genetics, Not Environment, Explain Differences in Students' Educational Achievement

It turns out that differences in educational achievement depends more on genetics than the environment. Scientists have discovered that while teachers, schools and families do play a role in how well a student does, their genes are more important at the end of the day.

Talent is Unfair and Genes Can’t Be Used to Change That

Talent is unfair. One can quibble about what it actually is. But there is little doubt that it is something that emerges not just from the genes but also from their interaction with the environment. Different people are born with different aptitudes for different things. Some of these aptitudes help...
