Not only are tumors are different from one another, but there can even be genetic differences within a single tumor.
New research pinpoints the genes that could counteract decades of bland breeding.
Why research that links our social behaviour to our genes is still controversial today.
It's possible to alter the make-up of a species such as a mosquito's ability to pass on the deadly malaria parasite. But we need to consider the pros and cons of such gene editing technology.
Understanding how genes influence people's behaviour doesn't lead to fatalism.
Animals that group together to fight off evolutionary pressure may actually evolve faster.
The answer – fewer than are in a banana – has implications for the study of human health and raises questions about what generates complexity anyway.
An important cell function called endocytosis is revealing a lot about how Alzheimer's develops.
Scottish Folds are adorable cats with folded ears and owl-like faces. But their cuteness also condemns them to a life of suffering.
Genes aren't destiny.
It is an illness that runs in families – but there are other factors which go beyond inheritance.
Even if intelligence has a genetic basis, this doesn't make educational intervention pointless.
Scientists have uncovered the genetics that explain the snake's impressive length – and used the science to create extra-long mice.
Regulations, funding and public opinion around genetically enhancing future generations vary from country to country. Here's why China may be poised to be the pioneer.
How new species are created is at the core of the theory of evolution. Mammals may be a good example of how sex chromosome change drove major groups apart.
Genes are important in predicting the risk of myopia, but they alone cannot explain the epidemic.
How much privacy are we willing to give up in the name of cutting-edge science? And do we care about the kinds of research that will be done with our donations?
Some students struggle because of biological constraints on learning. This can be overcome to an encouraging degree, but only with special and adequate resources.
Look beyond transgenic techniques that add new genes to a species. People have used selective breeding techniques to change plants and animals for millennia – why not try them on mosquitoes?
Rotifers are tiny creatures found in ponds or puddles and can reproduce without sex. The theory says they should not have survived so how have they done it?
