Rabbits may hold key to solving mystery of human female orgasm

Study suggests climax may be an evolutionary hangover but crucial questions remain A possible explanation for one of biologys greatest mysteries, the female orgasm, has been bolstered by research showing that rabbits given antidepressants release fewer eggs during sex. The human female orgasm has long proved curious, having no obvious purpose besides being pleasurable. The scientists behind the study have previously proposed it might have its evolutionary roots in a reflex linked to the release of eggs during sex a mechanism that exists today in several animal species, including rabbits. Since humans have spontaneous ovulation, the theory goes that female orgasm may be an evolutionary hangover. They say the new experiment supports the idea. We know there is a reflex …

For women like me, postponing the menopause would be a blessing | Sonia Sodha

When would science have produced a fix? I am going to hazard a guess that it would have been quite some time ago.

Mind the green gap: access to nature shouldn’t be a luxury | Arwa Mahdawi

Arwa Mahdawi: Living in New York means getting used to seeing the citys population of mutant squirrels. No wonder I need to escape One of my favourite things to do in New York is to go on long nature walks around the city.

My point here is that while Manhattan is full of natural delights, they are of a limited variety. I …
