An estimated 4,000 people are waiting for heart transplants, but the donated organs only last six hours outside a body. Duke University’s method, could extend that timeline and save lives.

Doctors bring dead donor heart back to life in US first
A heart transplant team at Duke University, North Carolina, has become the first in the US to reanimate the heart of a deceased donor and transplant it into a recipient.

Artificial neurons which could replace lost brain cells in Alzheimer’s, developed by scientists
Artificial neurons which could be implanted in the brain to repair the damage caused by Alzheimer’s disease or other neurodegenerative conditions, have been invented by scientists.
The electronic cells, developed by teams at the University of Bath and a team of international collaborators, sit on a silicon chip and mimic the responses of biological neurons when triggered by the nervous system.
Neurons are specialised cells which transmit nerve impulses, allowing parts of the body to communicate, and are the core components of the brain, spinal cord and nervous system. They are also present around the heart.
Family thankful for new technique that eases giving gift of life
More than 10,000 people are waiting for a lifesaving liver transplant.
The liver is one of the only organs that can be donated from a living person, and now, a new technique is making it easier than ever before to give the gift of life.
Nikko Velazquez, 29, watched helplessly as his girlfriend’s father, Abraham Aviv, 66, experienced end stage liver disease.
World first as artificial neurons developed to cure chronic diseases
Artificial neurons on silicon chips that behave just like the real thing have been invented by scientists—a first-of-its-kind achievement with enormous scope for medical devices to cure chronic diseases, such as heart failure, Alzheimer’s, and other diseases of neuronal degeneration.
Critically the artificial neurons not only behave just like biological neurons but only need one billionth the power of a microprocessor, making them ideally suited for use in medical implants and other bio-electronic devices.
The research team, led by the University of Bath and including researchers from the Universities of Bristol, Zurich and Auckland, describe the artificial neurons in a study published in Nature Communications.
