Scientists have discovered that the high pressure in the eye that occurs with most common forms of glaucoma can trigger two genes that work together to cause vision loss, which may help pave the way for new glaucoma drugs.
Help may be on the way.
Scientists seem to have cracked the code behind the heritability of obesity.
Scientists have discovered that a single gene may reveal a weakness in the development of schizophrenia that could help doctors prevent the condition.
It’s naive to pretend there are no profound genetic and epigenetic differences between the sexes.

What produces the differences between men and women? Are they trivial or profound? Are they genetic or environmental, or both? And are men really closer genetically to chimpanzees than to women?

Until more is understood, it's sensible to limit experimentation that would make changes to germ line cells that would be passed on to future generations.

Children who tend to do well in one subject tend to do well in others, largely for genetic reasons.
There are many reasons why some people get very grumpy when they haven’t eaten for a while.
"Hangry" is an amalgam of hungry and angry that describes the distinct grumpiness that some people experience when they haven't eaten for a while. Ring a bell?
BRCA1 and BRCA2 gene mutations prompted Angelina Jolie to have a preventative double mastectomy and surgery to remove both ovaries.
What if you could take a simple test to reveal your individual risk of developing a range of cancers and hundreds of other diseases?
Families share genes but that doesn’t mean no individual in a family should be accorded privacy about their genetic tests.
When a family member dies from a disease caused by a genetic mutation, doctors have to decide whether to share the deceased person's test results with the rest of the family.

It's not genes that make mammals so different but the 'on/off' switching.
As viruses replicate, their genome changes.

Three metres of DNA is looped and folded so it fits into a tiny human cell nucleus, but what other effects does this have?
When scientists first decided to sequence the human genome, it seemed an impossibly large and complicated challenge. A decade since achieving this aim, scientists are faced with a similarly overwhelming…
