The scans “show people it was worth
carrying on even though my body was unresponsive.”
Silent
Minds

Jerome Groopman
What
scanning techniques are revealing about vegetative patients.
Brain scans showed one patient was able to imagine playing
tennis.
|
“Ten years
ago, Adrian Owen, a young British neuroscientist, was working at a
brain-imaging center at Addenbrooke’s Hospital, at the University of
Cambridge. He had recently returned from the Montreal Neurological
Institute, where he used advanced scanning technology to map areas of
the brain, including those involved in recognizing human faces, and he
was eager to continue his research. The imaging center was next to the
hospital’s neurological intensive-care unit, and Owen heard about a
patient there named Kate Bainbridge, a twenty-six-year-old schoolteacher
who had become comatose after a flulike illness, and was eventually
diagnosed as being in what neurologists call a vegetative state. Owen
decided to scan Bainbridge’s brain. ‘We were looking for interesting
patients to study,’ he told me. ‘She was the first vegetative patient I
came across.’
“For four
months, Bainbridge had not spoken or responded to her family or her
doctors, although her eyes were often open and roving. (A person in a
coma appears to be asleep and is unaware of even painful stimulation; a
person in a vegetative state has periods of wakefulness but shows no
awareness of her environment and does not make purposeful movements.)
Owen placed Bainbridge in a
PET scanner, a machine
that records changes in metabolism and blood flow in the brain, and, on
a screen in front of her, projected photographs of faces belonging to
members of her family, as well as digitally distorted images, in which
the faces were unrecognizable. Whenever pictures of Bainbridge’s family
flashed on the screen, an area of her brain called the fusiform gyrus,
which neuroscientists had identified as playing a central role in face
recognition, lit up on the scan. ‘We were stunned,’ Owen told me. ‘The
fusiform-gyrus activation in her brain was not simply similar to normal;
it was exactly the same as normal volunteers....’”

“His mother rejected the

dysfunction is not worth living....”
Awakenings
by
Wesley J. Smith
The
Schiavo case revisited.
“On October 19, only months after being nearly dehydrated to death when
his feeding tube was removed, Jesse Ramirez walked out of the Barrow
Neurological Institute in Phoenix on his own two legs. Ramirez is lucky
to be alive. Early last June, a mere one week after a serious auto
accident left him unconscious, his wife Rebecca and doctors decided he
would never recover and pulled his feeding tube. He went without food
and water for five long days. But then his mother, Theresa, represented
by lawyers from the Arizona-based Alliance Defense Fund, successfully
took Rebecca to court demanding a change of guardianship on the grounds
that Rebecca and Jesse’s allegedly rocky marriage disqualified her for
the role.
“The judge ordered that Jesse be temporarily rehydrated and nourished.
Then Jesse regained consciousness. Now, instead of dying by dehydration,
he will receive rehabilitation and get on with his life—all because his
mother rejected the reigning cultural paradigm that a life with profound
cognitive dysfunction is not worth living.
“Ramirez is only the latest instance of an unconscious patient waking up
after being consigned to death by dehydration....”

Aging with the Boomers
by Yuval
Levin
The coming geriatric mindset.
“In an aging society, health
care is bound to be an increasingly dominant political concern. And
everybody knows American society is aging. The portion of our population
over the age of 65 has nearly doubled in the last half century, and will
just about double again in the next half century. The oldest of the old,
Americans over the age of 85, are now the fastest growing portion of the
population. Older people have more health problems, so a society with
more older members will naturally be more concerned about medicine and
health care.
“But beyond the simple
demographics, there is a more profound and understated cultural force
compelling our coming obsession with aging, decline, and health care. In
the coming decades, American society is likely to age in another way,
more subtle but no less crucial. Our self-image, which for more than
five decades now has been a baby-boomer self-image, will likely grow old
as the boomers do.
Defining America
“In countless ways large and small, America’s understanding of its
recent history is a baby-boomer biography. There are of course many
crucial exceptions, but the broad pattern is striking....”

An announcement

Cloned
Monkey Stem Cells Produced

Stem
cells extracted from cloned primate embryos.
The skin cell inserted into a primate egg (shown) came from
a monkey called Semos - also the name of the god in the
popular sci-fi work Planet of the Apes.

“Researchers
have for the first time created cloned primate embryos and used them to
make embryonic stem-cell lines. The achievement has led to speculation
about when similar success in humans might open up the door for
therapeutic cloning.
“Embryonic
stem cells can differentiate into almost any cell in the body and so
have tremendous potential for therapy. If they are taken from an embryo
cloned from a patient, as they were here from monkeys, they would be
genetically matched and thus avoid immune rejection....
“A team led
by Shoukhrat Mitalipov at Oregon Health and Science University in
Portland, had been trying for nearly a decade to achieve reproductive
cloning in primates, and had used some 15,000 eggs in the process. After
[Korean Woo Suk] Hwang’s results turned out to be fraudulent, the group
decided to move from reproductive cloning to try to establish a cloned
embryonic stem-cell line instead—theoretically, a more achievable
goal....”

Corrupting both church and hospice—the
United Churches of Christ include physician-assisted suicide in one of
their end-of-life programs...
The UCC’s Ethical Suicide
Parlor
by
Dennis Di Mauro
“On September 18, United
Church of Christ minister Kristi Denham announced that a new
organization of clergy called the End of Life Consultation Service (ELCS)
had been created that would be devoted to ministering to critically ill
medical patients. Rev. Denham explained that this organization would
‘help terminal patients access hospice, pain treatment, and other
excellent end of life care.’
“At first glance, the ELCS
sounds like a charitable Christian group devoted to helping the sick and
suffering, or another new ministry devoted to providing spiritual
assurance to the gravely ill. Well, not exactly. What makes this
organization different from many others is that the ELCS’s main purpose
is to assist medical patients in planning their own deaths. And as might
be expected, one of the options for a patient’s death offered by the
ELCS includes committing suicide.
“The new organization plans
to man a 1-800 hotline that would provide potential callers with
‘volunteers [who would] visit patients and families in the home, and
together they [could] identify a path to peaceful dying, well-suited to
an individual’s illness and circumstances.’ After the consultation, the
clients would then be free to ‘obtain and self-administer the means’ of
killing themselves....”

The insurance actuaries are paying
attention...abortion affects their bottom line...
The Breast Cancer
Epidemic
Patrick Carroll considers
the risk factors and the challenges faced in forecasting
future incidence rates of
breast cancer.
“The incidence of breast
cancer is increasing. There are several reasons for actuaries to attend
to this epidemic.
“The increase in incidence
is considerable, averaging over 80% across all ages since the
1970s when registration was
set up in Great Britain....
Risk factors driving the trends
“Most of the known risk factors are
reproductive, pregnancy related or hormonal. There is hormonal activity
and breast cell development during pregnancy. Induced abortion has a
carcinogenic effect that is greater when the woman is nulliparous (no
previous full-term pregnancy) by leaving the breast cells in a state of
interrupted hormonal development where they are more susceptible to
cancer. Full-term pregnancies leave breast cells more fully developed
and resistant to breast cancer. Breast-feeding confers additional
protection. Oestrogen, progestin and other female hormones, whether
naturally produced or administered medically, fuel breast cancer
development.
“Seven known reproductive risk factors could be
driving the trends:
- Abortion Most British abortions (53%) are nulliparous and the subsequent breast cancer risk is greater here.
- Age at first birth A low age is protective, as made known by British epidemiologists.
- Childlessness increases the risk Nuns have long been known to have a higher risk of breast cancer.
- Fertility More children increase protection.
- Breast-feeding This gives additional protection, now estimated by British epidemiologists.
- Hormonal contraceptives These contain oestrogen and progestin, and are conducive to breast cancer.
- Hormone replacement therapy (HRT) This contains female hormones and is likewise conducive to breast cancer....”

Why a
Child’s Best Friend is His Robotot
“Children could soon be making
friends with robots at nursery school. Scientists have developed a
childlike machine that toddlers can be taught to regard as human. It is
hoped that the robots will help to improve the children’s behaviour and
social skills.
“Scientists studied how children
aged between ten months and two years reacted to a silver robot placed
in a room with them. The robot, which is called QRIO and was built in
Japan, can interact with humans, walk, sit down, stand up, move its
arms, turn its head and even dance and giggle....

Designing a stronger, meaner mouse...
The Lance Armstrong
Mighty Mouse
See how they run! Watch the mouse
leave its normal partner in the dust in this
video.
“Scientists’ latest
improvement on nature is a ‘mighty mouse’ that can run at 20 meters a
minute for up to six hours before stopping. This genetically engineered
mouse eats 60% more than normal mice but is still fitter and lives and
breeds for longer.
“‘They are metabolically
similar to Lance Armstrong biking up the Pyrenees. They utilize mainly
fatty acids for energy and produce very little lactic acid,’ says
Richard Hanson, biochemist at Case Western Reserve University and the
man behind the new mice. In the Journal of Biological Chemistry,
Hanson details how over-expression of the gene for the enzyme
phosphoenolypyruvate carboxykinases produces these effects, although it
isn’t clear yet exactly what this enzyme does....
“A rather excitable article
in the UK’s Independent says the new mouse is ‘raising the prospect that
the discovery may one day be used to transform people’s capacities’.
Personally I hope not, as the researchers also found the new mice were
‘markedly more aggressive’ than controls....”

Future of Science: ‘We will have the power of

A leading theoretical
physicist has tapped the best scientific brains of the age to provide a
startling vision of the future.
Welcome to
the future: Michio Kaku and a robot
|
“Just before Sir Isaac
Newton died, he described how humbled he felt by the thought that he had
glimpsed only a fraction of the potential of the great scientific
revolution he had helped to launch: ‘I seem to have been only like a boy
playing on the seashore and diverting myself in now and then finding a
smoother pebble or prettier shell than ordinary, while the great ocean
of truth lay all undiscovered before me.’
“Three centuries later, that
great ocean of truth is not so mysterious. According to the theoretical
physicist Professor Michio Kaku of the City College of New York, we are
entering an empowered new era: ‘We have unlocked the secrets of matter.’
“‘We have unravelled the
molecule of life, DNA. And we have created a form of artificial
intelligence, the computer. We are making the historic transition from
the age of scientific discovery to the age of scientific mastery in
which we will be able to manipulate and mould nature almost to our
wishes.’
“Among the technologies he
believes will change our lives in the coming decades are cars that drive
themselves, lab-grown human organs, 3D television, robots that can
perform household tasks, eye glasses that double as home-entertainment
centres, the exploitation of genes that alter human ageing and the
possibility of invisibility and forms of teleportation....”

Worth considering...
from
Technologies of Humility
by Sheila
Jasanoff
Researchers and policy-makers need
ways for accommodating the partiality of scientific knowledge and for
acting under the inevitable uncertainty it holds.
D. Parkins
|
“The great mystery of modernity is
that we think of certainty as an attainable state. Uncertainty has
become the threat to collective action, the disease that knowledge must
cure. It is the condition that poses cruel dilemmas for decision-makers;
that must be reduced at any cost; that is tamed with scenarios and
assessments; and that feeds the frenzy for new knowledge, much of it
scientific.
“For a long time we accepted lack
of certainty as humankind’s natural lot. What has happened to reverse
that presumption...?
“Science fixes our attention on the
knowable, leading to an over-dependence on fact-finding. Even when
scientists recognize the limits of their own inquiries, as they often
do, the policy world, implicitly encouraged by scientists, asks for more
research. For most complex problems, the pursuit of perfect knowledge is
asymptotic. Uncertainty, ignorance and indeterminacy are always present.
“We need disciplined methods to
accommodate the partiality of scientific knowledge and to act under
irredeemable uncertainty. Let us call these the technologies of
humility. These technologies compel us to reflect on the sources of
ambiguity, indeterminacy and complexity. Humility instructs us to think
harder about how to reframe problems so that their ethical dimensions
are brought to light, which new facts to seek and when to resist asking
science for clarification. Humility directs us to alleviate known causes
of people’s vulnerability to harm, to pay attention to the distribution
of risks and benefits, and to reflect on the social factors that promote
or discourage learning....
“This call for humility is a plea
for policy-makers to cultivate, and for universities to teach, modes of
knowing that are often pushed aside in expanding scientific
understanding and technological capacity. It is a request for research
on what people value and why they value it. It is a prescription to
supplement science with the analysis of those aspects of the human
condition that science cannot easily illuminate. It is a call for policy
analysts and policy-makers to re-engage with the moral foundations for
acting in the face of inevitable scientific uncertainty.”
