The brains' immune systems kicked in. Neuron samples could carry an electrical signal. Some brain cells even responded to drugs. The researchers have managed to keep some brains alive for up to 36 hours, and currently do not know if Brain Ex can have sustained the brains longer.
As a control, other brains received either a fake solution or no solution at all. None revived brain activity and deteriorated as normal. The researchers hope the technology can enhance our ability to study the brain and its cellular functions.
One of the main avenues of such studies would be brain disorders and diseases. This could point the way to developing new of treatments for the likes of brain injuries, Alzheimer's, Huntington's, and neurodegenerative conditions. It immediately offers a much better model for studying the human brain, which is extraordinarily important, given the vast amount of human suffering from diseases of the mind [and] brain," Nita Farahany, the bioethicists at the Duke University School of Law who wrote the study's commentary, told National Geographic.
Before anyone gets an Island of Dr. Moreau vibe, it's worth noting that the brains did not approach neural activity anywhere near consciousness. The Brain Ex solution contained chemicals that prevented neurons from firing. To be extra cautious, the researchers also monitored the brains for any such activity and were prepared to administer an anesthetic should they have seen signs of consciousness.
Even so, the research signals a massive debate to come regarding medical ethics and our definition of death. Most countries define death, clinically speaking, as the irreversible loss of brain or circulatory function. This definition was already at odds with some folk- and value-centric understandings, but where do we go if it becomes possible to reverse clinical death with artificial perfusion?
One possible consequence involves organ donations. Some European countries require emergency responders to use a process that preserves organs when they cannot resuscitate a person.
They continue to pump blood throughout the body, but use a "thoracic aortic occlusion balloon" to prevent that blood from reaching the brain. The system is already controversial because it raises concerns about what caused the patient's death. But what happens when brain death becomes readily reversible? Stuart Younger, a bioethicist at Case Western Reserve University, told Nature that if Brain Ex were to become widely available, it could shrink the pool of eligible donors. It will be a while before such experiments go anywhere near human subjects. A more immediate ethical question relates to how such experiments harm animal subjects.
Ethical review boards evaluate research protocols and can reject any that causes undue pain, suffering, or distress. Since dead animals feel no pain, suffer no trauma, they are typically approved as subjects. But how do such boards make a judgement regarding the suffering of a "cellularly active" brain?
The distress of a partially alive brain? Another science fiction story that comes to mind when discussing this story is, of course, Frankenstein. As Farahany told National Geographic : "It is definitely has [sic] a good science-fiction element to it, and it is restoring cellular function where we previously thought impossible. But to have Frankenstein , you need some degree of consciousness, some 'there' there. But we are one step closer to that possibility. She's right. The researchers undertook their research for the betterment of humanity, and we may one day reap some unimaginable medical benefits from it.
The ethical questions, however, remain as unsettling as the stories they remind us of. Big Think Edge For You. Big Think Edge For Business. Preview an Edge video.

Cushioned shoes aren't good for your feet.
More and more research points to a serious mistake we made in how biomechanics works. A new study from Helsinki found that the more you cushion your feet, the more likely you'll get injured. This follows previous studies showing that cushioned shoes leave you more susceptible to pain and injury. Not everyone is born to run. But most certainly — not everyone is born to run barefoot.
Some people need more support on their feet than others. It just means their body naturally overpronates more than usual — and a supportive running shoe will offer a bit of support to correct that overpronation. The modern running shoe, believe it or not, is a good thing. It allows those who are not naturally inclined to run the opportunity to run. The modern day running shoe is not the cause of injury. It has nothing to do with gait. It has nothing to do with those over-cushioned, over-supportive running shoes. It has more to do with the fact that most people are carrying too much weight.
They start too fast. They run too much. Then their knees get sore, and they push through — until they get hurt.
Running technique problems
If you get hurt from wearing a particular shoe, try a different shoe. There are lots of kinds of running shoes. Try different brands, different widths, different levels of cushioning and support. There are options. Go to your local running store and find your fit. It may take a few different trips — but I promise a good fit does exist. In other words, do what the pros do.
