Researchers often use the genitalia of insects to differentiate species, since they are a reliable signature of a species uniqueness. A newly discovered beetle has been found to have genitalia that look remarkably similar to a bottle opener.
Scientists have created an infant ‘chimeric’ monkey by injecting a monkey embryo with stem cells from a genetically distinct donor embryo. The resulting animal is the first live-born chimeric primate to have a high proportion of cells originating from donor stem cells. However, the monkey had to be euthanized when it was...
Scientists have filmed an ancient egg-laying mammal named after Sir David Attenborough for the first time, proving it isn’t extinct as was feared....
This is a screenshot of my weather app showing forecasted (smooth blue/purple) rain of the French Arome model VS rain radar (sharp green/yellow contours). It actually does a pretty good job on the large scale but the details aren’t always quite right. Dies anyone know how rain probabilities are computed from these models...
Cytoplasmic lattices (bundles of fibres floating in the cytoplasm) in mammalian egg cells seem to be storage sites for many proteins that are essential for the development of the early embryo. The discovery indicates that their absence, which can be determined by genetic testing, would point towards infertility of the eggs....

A simulation suggests that fine particles played a stronger role in cooling the planet and stalling photosynthesis after an asteroid impacted the Earth....
It is not obvious why selection should favor menopause or the continued survival of individuals that can no longer reproduce. The famous Grandmother Hypothesis had been used to explain the evolutionary significance of menopause. A new study conducted on the Ngogo chimpanzees community of wild chimpanzees in Uganda challenges...
It’s not really news after a decade, but I still think it’s worth a look. This is something I think about sometimes, and it’s better to let the actual scholars speak....
