Changes in placenta could mean males born to older mothers more prone to heart problems

A new study in rats shows that older mother rats develop poorer placentas which are in turn related to later risk of heart problems in their male offspring. The study, published in the journal Scientific Reports, shows that both male and female offspring are smaller in size when the mother is older. However, the placental development in older mothers with male fetuses is especially impaired, leading to worse placental function. As a result, heart problems are more common in later life in these offspring, as is high blood pressure.

Medicinal plants: from genes to drugs

We eat plants, wear their products, burn them for fuel, and use them to build our houses. Plants are the very basis of the food chain on earth. They are also the source of oxygen in the atmosphere, and a treasure house containing a host of compounds that have biological effects on the body. Some of these chemicals are produced as self-defence, to guard against pests and diseases.

Kin care and mate retention rated as the most important motivations in people's lives

Across the globe, caring for loved ones is what matters most. But, for decades this has not been the focus of many social psychology studies.
