For the first time, scientists have figured out how to regrow not just the bone but even the joints of a mouse’s amputated toes.

Normally mammals like mice don’t regenerate body parts — meaning the new development could help lead to futuristic medical procedures in which amputees are able to grow back their missing limbs.

Expanding Reach
Thanks to a cocktail of proteins that stimulate regeneration, lab mice grew back a greater portion of their amputated toes than was possible in past experiments,...
Scientists have developed a “needle pill” that could allow diabetics to take insulin without the need for daily injections.

The pea-sized capsule contains a small needle made of solid, compressed insulin, which is injected into the stomach wall after the capsule has been swallowed.

When tested in pigs, the device worked consistently and was able to deliver equivalent doses of insulin to those required by someone with diabetes.

Researchers in 2018 achieved a new kind of chimeric first, producing sheep-human hybrid embryos that could one day represent the future of organ donation – by using body parts grown inside unnatural, engineered animals.

With that end goal in mind, scientists created the first interspecies sheep-human chimera in February, introducing human stem cells into sheep embryos, resulting in a hybrid creature that's more than 99 percent sheep – but also a tiny, little bit like you and me.

Admittedly, the human portion of the embryos created in the experiment – before...
In 2017 researchers figured out how to make fresh wounds heal as normal, regenerated skin, instead of the usual scar tissue - something that was previously thought to be impossible in mammals.

"Essentially, we can manipulate wound healing so that it leads to skin regeneration rather than scarring," said one of the team, George Cotsarelis, chair of the Department of Dermatology at the University of...
From time to time, there are whispers that red wolves still roam parts of Texas. There shouldn't be any there – the animals were officially declared extinct in the wild roughly 40 years ago.

But a new discovery lends at least a skerrick of truth to some sightings, at least on Galveston Island on the Texas coast. Genetic testing of road-kill has revealed that a population of dogs on the island carry the 'ghost' genes of this recently vanished species.

A new study has just revealed that genetically modified pig hearts have now kept baboons alive for up to 195 days. This stuff, reminiscent of sci-fi nightmares, is actually a huge step towards increasing the pool of donor heart organs available for human patients.

Currently, the supply of donor hearts is not enough to save everyone experiencing terminal heart failure, and many people...
Spring loaded mouth gags are a recognised cause for cats to wake up with cortical blindness. This unnecessary complication is thought to arise from excess tension created by the springs, leading to Maxillary artery compression. The subsequent hypoxia results in central blindness that can be temporary or permanent.

It is recommended to use nail clippers to cut a 25g needle cap into 20mm length and use this between the canine teeth instead. Studies have shown that this length is safe.
