00:45 Making a map of the human heartThe human heart consists of multiple, specialised structures that all work together to enable the organ to beat for a lifetime. But exactly which cells are present in each part of the heart has been difficult to ascertain. Now, a team has combined molecular techniques to create an atlas of the developing human heart at an individual cell level. Their atlas provides insights into how cell communities communicate and form different structures. They hope that this knowledge will ultimately help in the treatment of congenital heart conditions, often caused by irregular development of the heart.

Menopause is a rare phenomenon, only known to occur in a few mammalian species. Several of these species are toothed whales, such as killer whales, beluga whales and narwhals. But why menopause evolved multiple times in toothed whales has been a long-standing research question. To answer it, a team examined the life history of whales with and without menopause and how this affected the number of offspring and ‘grandoffpsring’. Their results suggest that menopause allows older females to help younger generations in their families and improve their chances of survival.
