‘Not right now’: Key marine species turned off sex by plastic chemicals

A new study has found that chemical additives in everyday plastic might be stopping – or, at best, interrupting – the reproductive habits of a shrimp-like species that is key to the marine food chain. The findings provide a different perspective on the… Continue reading ‘Not right now’: Key marine species turned off sex by plastic chemicals

This sea worm’s butt detaches from its body to swim off in search of love

In one of the strangest paths to reproduction, this tiny Japanese sea worm actually grows a ‘mini-me’ at its rear end, which it then deploys so it can swim off on its own in search of similar autonomous tail of the opposite sex to spawn with. The worm,… Continue reading This sea worm’s butt detaches from its body to swim off in search of love

Newfound beetle has a penis like a bottle opener, is named after beer

Step aside, ducks, with your corkscrew phalluses: we have a new member of the animal kingdom sporting a penis that resembles a tool you’d more likely expect to see behind a bar than in a biological body plan.Continue ReadingCategory: Biology, ScienceTa… Continue reading Newfound beetle has a penis like a bottle opener, is named after beer

Higher cell phone usage associated with lower sperm count in new study

A study of nearly 3,000 Swiss men over the course of 13 years has shown a link between frequent cell phone use and a decrease in sperm quantity. What’s more, today’s 4G and 5G networks may have less of an impact than older communications technology.Con… Continue reading Higher cell phone usage associated with lower sperm count in new study

Mouse embryos successfully grown in space for the first time

In one small step for humankind, scientists have seen a fertilized mouse egg develop naturally and normally into early embryonic form. While a long way to go, it’s a positive sign that mammalian – namely, human – reproduction can take place in space.Co… Continue reading Mouse embryos successfully grown in space for the first time

Croak it: Female frogs fake death to avoid sex with unappealing males

In the wild world of nature, where an organism’s sole aim is to succeed at passing on their genes at any cost, it’s not surprising many species have aggressive, and even deadly, mating behaviors.Continue ReadingCategory: Biology, ScienceTags: Frogs, Re… Continue reading Croak it: Female frogs fake death to avoid sex with unappealing males

Virgin birth at Cambridge thanks to genetically modified fruit flies

By decoding a genetic process responsible for asexual reproduction, researchers induced virgin births for the first time in a normally sexual fruit fly species. It was then discovered that the remarkable trait was passed down to all of the flies’ daugh… Continue reading Virgin birth at Cambridge thanks to genetically modified fruit flies
