Why do humans possess a twisted birth canal?
The relatively narrow human birth canal presumably evolved as a "compromise" between its abilities for parturition, support of the inner organs, and upright walking. But not only the size of the birth canal, also its complex, "twisted" shape is an ev.....»»

NASA watchdog report: 100+ cracks on heat shield biggest threat to human moon mission
The damage to the Orion capsule from the Artemis I mission is already top of mind for NASA as it works to make the Artemis II mission safe for humans. But a new agency report has revealed the extent of the problem, including scores of cracks in Orion.....»»
How aging clocks tick: New study points to stochastic changes in cells
Aging clocks can measure the biological age of humans with high precision. Biological age can be influenced by environmental factors such as smoking or diet, thus deviating from chronological age that is calculated using the date of birth. The precis.....»»
