We know much about how embryos develop, but one key stage – implantation – has remained a mystery. Now, scientists from Cambridge have discovered a way to study and film this ‘black box’ of development.
Scientists have discovered that, when upright, stick insects don’t stick. Instead, they deploy special hairy pads designed to create huge amounts of friction from the tiniest of pressure increases - ensuring that the insects grip but don’t stick.
Teenage boys with symptoms of depression and raised levels of the stress hormone cortisol are up to 14 times more likely to develop major depression than those without these traits, Cambridge researchers have found.
New study’s findings overturn theory of personal risk preference as a ‘stable trait’, and show that real source of instability in risk behaviour “lurks deep in the physiology of traders and investors”.
