Horseshoe crabs – a species which lost more than half its population in recent history – have started to thrive once more on the Philippine islet of Pangatalan. Efforts to restore the area have led to many of the crabs returning, and the area has now become protected to encourage future growth of the general marine and wildlife populations. Initiatives like this are hoped to be replicated elsewhere in the world to stimulate specific animal population growth.
Two genetically modified pig hearts have successfully been transplanted into humans who had recently been on life support. This has been made possible as the pig genes – that would normally cause a transplant rejection in a human – were successfully ‘turned off’. Meanwhile, the pigs bred for the transplant had been living in special diseases-free facilities. The transplantation of modified pig hearts could lead to the end of the shortage of donor organs, with 105,000 people waiting for an organ transplant in the US alone.
