Megalodon shark’s enormous babies ate their siblings in the womb
Megalodons – the extinct giant sharks that lived in most of Earth’s oceans about 3 million years ago – gave birth to babies that were larger than adult humans, scientists say. Source: https://earthsky.org/earth/megalodon-extinct-giant-shark-enormous-babies…
Identical Twins Are Not So Identical, Study Suggests
An anonymous reader quotes a report from The Guardian: Genetic differences between identical twins can begin very early in embryonic development, according to a study that researchers say has implications for examining the effects of nature versus nurture. Identical — or monozygotic — twins come from a single fertilized egg that splits in two. They are important research subjects because they…
Tiny worm squirts milk out of its vulva to feed its offspring
The nematode worm Caenorhabditis elegans has been used by biologists for decades, but it has been hiding a secret the whole time: it makes milk Source: https://www.newscientist.com/article/2260637-tiny-worm-squirts-milk-out-of-its-vulva-to-feed-its-offspring/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Corals are first animals seen to pass on mutations acquired as adults
Adult corals can pass on mutations they have acquired during their lives to their offspring, like some plants do, overturning a belief that no animals can hand down such mutations Source: https://www.newscientist.com/article/2258746-corals-are-first-animals-seen-to-pass-on-mutations-acquired-as-adults/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Backdoor In Kids’ Smartwatch Makes It Possible For Someone To Covertly Take Pictures, Record Audio
The Xplora 4 smartwatch, made by Chinese outfit Qihoo 360 Technology Co, and marketed to children under the Xplora brand in the US and Europe, can covertly take photos and record audio when activated by an encrypted SMS message, says Norwegian security firm Mnemonic. The Register reports: This backdoor is not a bug, the finders insist, but a deliberate, hidden feature….
Gene Editing To Produce ‘Super Dad’ Livestock
Scientists have produced gene-edited animals they say could serve as “super dads” or “surrogate sires.” The BBC reports: The pigs, goats, cattle and mice make sperm carrying the genetic material of donor animals. The researchers used a hi-tech gene editing tool to knock out a male fertility gene in animal embryos. The animals were born sterile, but began producing sperm after…
