The Fight Isn’t Over

Question: Has feminism succeeded?

Gloria Steinem:  It’s hard to measure success when we’re dealing with between 500 and 5,000 years of patriarchy depending on which continent we sit, so I would say feminism has been successful and we have a huge distance to go, huge.  For instance, we’ve demonstrated in this and other modern countries or industrialized countries that women can do what men can do, but we have not demonstrated that men can do what women can do therefore children are still mostly raised, hugely mostly raised by women and women in industrialized modern countries end up having two jobs one outside the home and one inside the home. And more seriously than that children grow up believing that only women can be loving and nurturing, which is a libel on men, and that only men can be powerful in the world outside the home, which is a libel on women. So that's huge step we haven’t taken yet.

Question: Will same-sex parenting couples help to challenge these notions?

Gloria Steinem:  Both single males who are parents and same-sex couples of men who are raising children that is certainly a great help because those children will grow up knowing that men can be as loving and nurturing as women.  They will be much less likely to falsely divide the world into masculine qualities and feminine qualities, but there is a bigger and deeper connection between the women’s movement and gay and lesbian movements, which has always been true.  I mean they always come together, and our adversaries are always the same because the male supremacist, patriarchal, ultra-right-wing, whatever you want to... religious fundamentalists, whatever you want to call it is devoted to saying that sex is only moral and okay when it is directed towards having children and occurs in patriarchal marriage, so the children are owned.

So what the means is that both for women, all women, whatever our sexuality, it’s crucial to our health that we are able to separate sexuality from reproduction.  I mean whether or not we can control when we give birth is the biggest element in our health, our education, our economic welfare, our life expectancy, everything. So it’s crucial that we are able to separate sexuality and reproduction. And of course same sex couples stand for, in a way, the separation of sexuality from reproduction, so our adversaries are really all the same people.

On campus, sometimes kids ask me, “Well why is the... why are religious fundamentalists against both lesbians and birth control?”  You know this seems inconsistent to them. But it’s not.  It’s consistent because they are against any form of sexuality, of sexual expression that can’t end in conception, which happens to be a huge lie about human sexuality.  Humans can experience the same sexual pleasure whether we can conceive or not.  Sexuality has always been for humans a form of communication, a way we express love and caring and bonding, not only a way we have children if we choose to.

Feminism has proven that women can do men’s jobs, but it hasn’t yet proven that men can do women’s jobs—like nurturing a child. This is both a libel to men and an undue burden on working mothers.

Yale scientists restore brain function to 32 clinically dead pigs

Researchers hope the technology will further our understanding of the brain, but lawmakers may not be ready for the ethical challenges.

Still from John Stephenson's 1999 rendition of Animal Farm.
Surprising Science
  • Researchers at the Yale School of Medicine successfully restored some functions to pig brains that had been dead for hours.
  • They hope the technology will advance our understanding of the brain, potentially developing new treatments for debilitating diseases and disorders.
  • The research raises many ethical questions and puts to the test our current understanding of death.

The image of an undead brain coming back to live again is the stuff of science fiction. Not just any science fiction, specifically B-grade sci fi. What instantly springs to mind is the black-and-white horrors of films like Fiend Without a Face. Bad acting. Plastic monstrosities. Visible strings. And a spinal cord that, for some reason, is also a tentacle?

But like any good science fiction, it's only a matter of time before some manner of it seeps into our reality. This week's Nature published the findings of researchers who managed to restore function to pigs' brains that were clinically dead. At least, what we once thought of as dead.

What's dead may never die, it seems

The researchers did not hail from House Greyjoy — "What is dead may never die" — but came largely from the Yale School of Medicine. They connected 32 pig brains to a system called BrainEx. BrainEx is an artificial perfusion system — that is, a system that takes over the functions normally regulated by the organ. Think a dialysis machine for the mind. The pigs had been killed four hours earlier at a U.S. Department of Agriculture slaughterhouse; their brains completely removed from the skulls.

BrainEx pumped an experiment solution into the brain that essentially mimic blood flow. It brought oxygen and nutrients to the tissues, giving brain cells the resources to begin many normal functions. The cells began consuming and metabolizing sugars. 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 BrainEx can have sustained the brains longer. "It is conceivable we are just preventing the inevitable, and the brain won't be able to recover," said Nenad Sestan, Yale neuroscientist and the lead researcher.

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.

"This is an extraordinary and very promising breakthrough for neuroscience. 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.

An ethical gray matter

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 BrainEx 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?

"This is wild," Jonathan Moreno, a bioethicist at the University of Pennsylvania, told the New York Times. "If ever there was an issue that merited big public deliberation on the ethics of science and medicine, this is one."

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 BrainEx were to become widely available, it could shrink the pool of eligible donors.

"There's a potential conflict here between the interests of potential donors — who might not even be donors — and people who are waiting for organs," he said.

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?

The dilemma is unprecedented.

Setting new boundaries

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. [The researchers] did not recover any form of consciousness in this study, and it is still unclear if we ever could. 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.

19th-century medicine: Milk was used as a blood substitute for transfusions

Believe it or not, for a few decades, giving people "milk transfusions" was all the rage.

Surprising Science
  • Prior to the discovery of blood types in 1901, giving people blood transfusions was a risky procedure.
  • In order to get around the need to transfuse others with blood, some doctors resorted to using a blood substitute: Milk.
  • It went pretty much how you would expect it to.
