#Nasty parasites turn up in dead otters CARDIFF U. UK) A variety of disease-causing parasites are turning up in the bodies of dead otters in the UK.

In humans the parasite can lead to miscarriage and retinal abnormalities. Parasitic flatwormsivided into two species Pseudamphistomum truncatum and Metorchis albidusere found in 18.3 percent of otters.

#Freedom Driver allows man with artificial heart to await transplant at home Heart failure patients awaiting organ transplants normally find themselves anchored to the hospital bed by a washing machine-sized device that keeps blood pumping through their veins.
This organ shortage means that sufferers of advanced heart failure are implanted with devices to aid in survival.

#Spinal implant could one day let paralyzed people walk again Three years ago scientists at The swiss Federal Institute of technology (EPFL) reported success in getting rats with severed spinal cords
to walk again. They did so by suspending the animals in a harness then using implants to electrically stimulate neurons in their lower spinal cord.
Although this ultimately resulted in the rats being able to run on their previously-paralyzed hind legs the technology still wasn't practical for long-term use in humans.
Although the researchers hoped that the technology could eventually find use in a rehabilitative neuroprosthetic system for humans there was at least one stumbling block#the implants
Now however the scientists have created a new type of implant which addresses that issue. It's known as the e-Dura as it's designed to be implanted on the spinal cord or cortex beneath the dura mater#that's the protective envelope that surrounds the nervous system.
The implant consists of a stretchy silicone substrate covered in cracked-gold conducting tracks leading to electrodes made from a silicon/platinum microbead composite.
In lab tests e-Duras implanted in rats caused no problems even after two months#according to EPFL traditional implants would have caused significant nerve tissue damage within that same amount of time.
