How has the media changed?

Question: How has media changed over the course of your career?

Barrett: I can’t imagine that it would have changed more in some ways.  The advent of the Internet has really changed many aspects of how journalism operates as a business.  The most pronounced and the most painful aspect of that is the very distinct migration of advertising dollars from traditional print and broadcast journalism over to the Internet.  Advertisers have lost the old time religion – the sense of confidence that the way you sell your products is by putting them next to traditional print journalism, or interspersed within broadcast journalism.  And their new religion is that the way you sell things is on the Internet.  Now that’s an exaggeration of course, because most of the dollars are still flowing toward the more traditional media in absolute terms.  But in terms of the growth, all of it is shifting over toward the Internet.  So that has caused great and mighty institutions to shake and shudder; newspaper chains that only 10 years ago were real titans to crumble and disappear right in front of us; and all of the big institutions to question how they can go forward as profitable businesses.  Having said all that, on the actual doing journalism side, what I do on a day-to-day basis hasn’t much changed at all.  I see my path as having really just continued.  I’ve tried to continue to do the kind of serious traditional and, in more recent years, long form journalism that I set out to do from the beginning.  And the tools I used – I don’t know whether my various employers would be happy to hear this – are the same tools I’ve always used: a pencil, pen, pad, and a very old-fashioned, I assure you, tape recorder.  And I transcribe all my own notes.  And I stare at them, and I go back and forth through them, and I start tapping things out.  Yes it’s on a computer now.  And when I started out in college I used to use a typewriter.  Do you even know what that is, a typewriter?  You heard of that?  When I was in college we used to type.  When I got my first full time journalism job at the Washington Monthly, which was a . . . which continues today – a small political magazine in Washington – we had typewriters.  And one of my early sort of extra-curricular assignments from my boss there, Charlie Peters, was, “Go out and get someone to buy these computer-things,” because we had no computers in 1985 at the Washington Monthly.  I had to go out and knock on the door of philanthropists, and finally found a very generous guy to give us $5,000 so we could buy two K-Pro PCs.  But the way I do my work hasn’t changed much since 1985.

Question: How do you deal with the information overload?

Barrett: I’m not saying I’m not overloaded with information.  I do feel we’re overloaded with information.  But when you get down to doing the work you really . . .  My view is you’ve gotta focus in on your subject.  And you focus in the same way.  You sit down with people and you talk to them

Despite deep shifts in the business of journalism, life on the beat is relatively unchanged.

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.

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. 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.
