Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into synthetic uterine tissue—revealing a key stage in reproduction. The resulting ...

A study based on a review of genetic and health information from more than 276,000 people finds strong support for a decades-old evolutionary theory that sought to explain aging and senescence. A ...

Aug. 11 (UPI) --A team of Spanish researchers announced Friday they have for the first time recorded video of a human embryo implanting itself in a simulated uterine wall, revealing never-before-seen ...

To Shakespeare’s Hamlet we humans are “the paragon of animals”. But recent advances in genetics are suggesting that humans are far from being evolution’s greatest achievement. For example, humans have ...

A team of researchers at the Institute for Bioengineering of Catalonia (IBEC) in Spain has succeeded, for the first time, in recording in real time and in 3D the implantation of a human embryo. This ...

The slow maturation of human children—often viewed as burdensome in modern parenting—is, in fact, a remarkable evolutionary achievement. Unlike other species, humans remain biologically immature and ...

Most animals, including humans, carry an internal lunar clock, tuned to the 29.5-day rhythm of the Moon. It guides sleep, reproduction and migration of many species. But in the age of artificial light ...

For the first time, scientists have created fertilizable human eggs from skin cells—an advance that the researchers say could pave the way for new infertility treatments, though the technology remains ...
