Snooze (too much), You Lose?

Excerpts
from article describing why seven hours of sleep may be well-advised
...
-
- - begin excerpts - - -
...
people who reported sleeping more than eight hours a night have
a 15 percent greater chance of dying, for any reason, than people
who sleep seven hours a night. The same holds true for those
who slept less than four or five hours, found researchers from
the University of California, San Diego, and the American Cancer
Society.
New
research finds an association
between the duration of sleep and
the length of a person's life
...
even if further research confirms that short or long sleepers
have higher mortality rates, experts say they will still stress
the importance of a good night's sleep, because living longer
does not necessarily mean living better.
...
'Sleeping your life away' could be more than a saying. Excessive
sleeping may increase your risk of an early death by up to 15%.
So hints a new analysis of data collected on one million people
by the American Cancer Society. The figures cast doubt on the
reputed benefits of eight hours' sleep a night.
People
with the longest lives get only seven hours of sleep each night,
find psychiatrists at the University of California, San Diego.
Why seven is the magic number is not clear. And sleeping more
appears to be riskier than sleeping less. On the short side,
increased mortality kicks in only when you get below four hours.
This
unprecedented peek into the habits of so many people claims
to be the first to determine the relationship between sleep
and mortality, while controlling for other factors such as weight,
smoking and exercise.
Currently,
the average American gets about six-and-a-half hours sleep,
much lower than the standard recommendation of eight hours.
The new analysis suggests that patients may seek treatments
unnecessarily in attempts to attain the eight-hour target. ...

(sample
grey parrot - not a

Excerpts
from article describing evidence that language and intelligence
are more widespread and complex in the animal kingdom than previously
thought:
-
- - begin article - - -
Meet
Griffin, the grey parrot, whose astonishing vocal and physical
skills are demonstrating just how smart the avian world really
is.
Griffin
has recently begun to play with objects and speaks English in
a way that raises fascinating questions about the thought processes
going on inside a bird's brain.
The
parrot will stack different-sized bottle caps in the right order,
for example. He will also mix up the English words he has learned,
and will say simple phrases, like "wanna green nut".
This
type of behaviour was once thought to be exclusive to humans,
great apes, and monkeys. Griffin suggests Parrots should be
added to the list. ...

Humans
Will 'Sail to the Stars'
Saturday, February

Excerpts
from article describing the manner in which humans may, some
day, be able to travel to distant locales ...
-
- - begin excerpts - - -
Scientists
have presented new ideas for the future exploration of planets
that circle far-away stars. Unlike
today's relatively small space vehicles such as the shuttle,
the cosmic craft of tomorrow will have to be the size of small
cities and be constructed in orbit.
... the 200 or so volunteers who went on a mission would have
to realise that they were taking up a one-way ticket and would
most probably never live to see the ship's final destination.
...
transporting large numbers of people across the galaxy would
require vast vessels driven by gigantic sails, blown across
deep space by intense bursts from a giant laser.

New
propulsion systems are
needed to go to the stars
...
An interstellar ship would be like an ark, carrying everything
the colonists might need, including greenhouses for growing
food and sophisticated manufacturing facilities.

Triumph
of America Made Flesh - Britney Spears, A to Z
Sunday,
February 17, 2002

Excerpts
from article
describing the way in which Britney personifies America ...
-
- - begin excerpts - - -
She
makes Madonna look matronly. She's global capitalism in a micro-mini.
She's junk food. Britney is the triumph of America made flesh
- one more time
Soon
after I started to investigate Britney Spears, I got the feeling
that I was outnumbered by her. At the age of 20, she has exponentiated.
She long ago established herself, according to the accountants,
as 'the bestselling female artist during any one-week period
in music history'.
...
She has become a collective fantasy, whose image inflames cyberspace.
Search engines spend much of their time servicing requests for
'Britney naked'. One internet site compounds 1,001
other Britney sites, each of which opens into labyrinthine
photo-galleries and encyclopaedic libraries of
tittle-tattle.
...
Wherever
you look, she is there - inside my head, and also lurking,
as I discovered, in every letter of the alphabet.
A
is for America, which Britney nubilely, precociously, go-gettingly
embodies. The country is a permanent adolescent like her; she
enacts its brash, mercenary dreams and its constitutional guarantee
that everyone's wishes will come true. 'Go for what you want,'
her mother told her when entering her in television
talent quests at the age of nine.
...
B is for Brittany, which is perhaps what her parents - back
in those benighted days before we had SpellCheck to help us
- named her after. To her family, she is known as Brit-Brit.
...
C is for Cola, Pepsi to be precise, which paid Britney £63,000
per second to jive and jiggle through the commercial breaks
on this year's Superbowl telecast. The show concluded with her
performance of an anthem entitled 'The
Joy of Pepsi'.
...
D is for Dolls, which Britney collects and also merchandises.
... You can buy
your own Britney, position her plastic limbs at will or
have her do striptease routines.
...
E is for Evil, which Britney incarnated at the age of 11 when
cast as a diabolical infant in a Broadway play based on the
horror film, The Bad Seed. She shrieked, hollered and rampaged
through the theatre in a fit of devilish ecstasy.
...
F is for Fan Base. Those battalions of randy teens are intrepid.
...
G is for Geek and Goob, which Britney sometimes calls herself.
...
H is for Horse. Britney does not ride, but could once be seen
- thanks to some digitally manipulated pixels - enjoying equine
sex in a remote corner of the internet. Is it for this that
Al Gore invented the information highway?
...
I is for Implants, euphemised by Britney as ''that
whole boob thing''. She denies having been pumped full of
silicone, and says: 'I just grew.'
...
J is for Justin Timberlake from the boy band *Nsync, who is
Britney's sweetheart.
...
K is for Kinesiology, in which Britney's brother, Bryan (as
I said, it's an alliterative household) majored at college.
Don't ask me for details of the curriculum. Maybe it involves
the study of Britney's piston-pumping, arm-flailing dance routines.
...
L is for Lolita and Lubrication, which go together. Britney
defines herself as a nymphet in Crossroads: 'I'm not a girl
but I'm not yet a woman,' she caterwauls. Though she has sternly
said: 'I don't want to be part of someone's Lolita thing', one
of her handlers must have studied Nabokov's novel.
...
M is for Moroccan vibe, which is how Britney describes the decorative
style of her Los Angeles pad.
...
N is for Na-Na-Na-Na-Na, the first line of a song in Crossroads.
...
O is for Octaves, of which Britney possesses four.
...
P is for Prayer, in which Britney places a reverent trust. A
sign in her Louisiana neighbourhood benignly advises: 'Drive
Carefully, Live Prayerfully.' Every night before she sleeps,
she does what she calls 'my devotional'. God pays particular
attention to Britney's murmured nocturnal requests, and, like
an obliging aerial DJ hosting a phone-in programme, immediately
answers them.
'I
would pray "I hope my song plays on a certain radio station
that's really big", and it would happen. Then, "I
hope they play the video on MTV", and they did.' Our Father
once reached down from heaven to grab Britney's leg and pull
a muscle in it during a dance routine: 'I think it was Him giving
me a sign that I needed a break. I thank Him for it.'
...
So far, Britney has not mimicked Madonna by masturbating with
a crucifix, but if she did she would probably have divine approval.
Can God be a dirty old man?
...
Q is for Quotations, inspirational slogans copied by Britney
into her Prayer Journal. This chronicles her 'spiritual journey',
the celestial equivalent of the more carnal car trip in Crossroads,
which leads from Louisiana to California where Britney at last
surrenders her expensive virginity.
...
R is for the Republican Party, which dotes on Britney. During
the election campaign in 2000, a Bush aide called her 'one of
our greatest assets'.
...
It's this merchandising operation, swollen by deals with Sunglass
Hut and Tommy Hilfiger as well as Pepsi, that the Republicans
admire. Britney sometimes refers to 'my package'. By this, she
does not mean the straining tops and jutting bottoms she wears
but to her product profile, her demographic reach and her market
penetration. Britney is global capitalism in a micro-mini.
S
is for Satisfaction. ... Britney often tells her adolescent
constituents to be proud of their sexuality, though she then
confusingly adds that they should not have sex before marriage.
...
T is for Totally, Britney's favourite adverb.
...
Asked whether she and Justin understood each other, she cooed:
'We totally do.' And, with a grateful glance at the sky, she
once asserted: 'I am totally blessed.'
...
U is for Umbilical Piercing. A diamond stud twinkles in Britney's
navel (and, while we're taking physiological inventory, she
also has a daisy tattooed on her toe). Her tummy bud is an innie,
not an outie, so the incision was excruciating. 'I guess I don't
have a good flap,' she said afterwards. 'You're supposed to
have a flap of skin that's thin, but mine's thick.' Can't you
just feel her pain?
V
is for Virginity, which Britney prizes and has sought to preserve.
Supporting the sacred pledge made by the young Christians who
adhere to a cult of chastity called True Love Waits, she famously
but non-committally said: 'I want to wait to have sex until
I'm married.' Then, sounding increasingly less convinced, she
added: 'I do. I want to wait. But it's hard.'
Her
defloration, so agonisingly delayed, at last occurs in Crossroads.
... The Baptist babe has given herself to a fallen angel, who
may be the bearer of the above-mentioned bad seed. If they felt
the earth move beneath the motel bed, it must have been the
San Andreas fault tearing open to protest at America's loss
of innocence.
...
W is for Wedding. Never mind about the devilish scenario described
in the previous entry. Britney's marriage will be pantheistic,
since she intends to wed the universe (having already coupled,
at least in their imaginations, with a goodly proportion of
the men in it).
...
X is for XXX, which is what some think Britney should be rated.
In one of her concerts, she made callisthenic love to the kind
of pole lapdancers like to impale themselves on, and in Crossroads
she performs in a karaoke bar wearing spiked-heel boots, ravished
cut-offs, a studded belt and a threadbare T-shirt with FREEDOM
emblazoned across it.
For
a Rolling
Stone session with the photographer David LaChapelle, she
seethed in her frilly bedroom as if it were a tart's boudoir,
then went outdoors to push a tiny bicycle wearing tinier shorts
with BABY spelled out in diamanté across one of her butt
cheeks.
...
Y is for Y-Fronts, which she dances in at the beginning of Crossroads.
The scene sums up Britney's teasing appeal: she is singing in
her bedroom, using a spoon as her microphone.
...
Z is for Zits, ... Britney's fatal flaw ... 'I love junk food,'
says Britney unrepentantly. Which is just as well, because,
come to think of it, that's pretty much what Britney is. Like
junk food, she sells instant gratification and, in doing so,
she triumphantly Americanises the supine earth. ...

Grumpy
People Born That Way
Sunday,
February 17, 2002

Excerpts
from
article which describes the evidence that a small active area
of the brain predisposes grumpy individuals to being naturally
inclined towards anxiety, irritability, and anger. ...
-
- - begin excerpts - - -
Grumpy people seldom need reasons to be in a bad mood, but
scientists have come up with the perfect excuse: they are
born that way.
So there is no point in telling the Victor Meldrews and Albert
Steptoes of the world to cheer up - their brains are simply
designed to be more grumpy than others.
Psychologist
Dr David Zald of Vanderbilt University in Nashville has identified
a tiny part of the brain which he believes governs people's
tendency to have regular bouts of irritability, anxiety or
anger. The more active that part of the brain, the more likely
someone is to suffer bad moods.
'It
looks like it is this part of the brain's activity that regulates
people's mood. It is also a part of the brain that controls
sweating, stomach acidity and heart rate and other physical
feelings associated with stress and bad moods,' said Zald.
The
culprit is a postage stamp-sized bit of the brain called the
ventromedial prefrontal cortex, which lies an inch or two
behind the right eye.
...
Those who experienced a lot of bad moods were also revealed
to have a lot of extra activity in the ventromedial prefrontal
cortex. ...

The
End of Tooth Decay?
Sunday,
February 17, 2002
Excerpts
from article
detailing a newly discovered way to eliminate tooth decay:
-
- - begin excerpts - - -
Scientists
believe they have found a way to stop tooth decay using a genetically
modified mouthwash. US researchers have developed the spray
and it is hoped clinical trials will begin in both the UK and
US by the end of this year.
Details
of the research were presented to the American Association for
the Advancement of Science annual meeting in Boston.
...
Tooth decay is caused not by sugar but by a bacterium which
lives in the mouth and turns the sugar into lactic acid. It
is this acid which affects the teeth.
Professor
Jeffrey Hillman, of the University of Florida has genetically
altered the bacterium called Streptococcus mutans into a form
which does not produce lactic acid and therefore does not cause
tooth decay.
Experiments
on animals have shown the GM bacterium took the place of the
bad bacterium once it was in the mouth.
The
GM bacterium did not cause tooth decay even when rats were fed
a high-sugar diet, and it even appeared sugar helped the bacterium
to colonise the surface of the tooth.

Professor
Hillman told the BBC: "Our approach has the potential,
if it works the way we anticipate that it will, of eliminating
most tooth decay." ...

Cannabis
Medical Tests
Monday,
February 18, 2002
Excerpts
from article
detailing the likely OK to use cannabis in the UK for some medical
treatments within two years:
-
- - begin excerpts - - -

Advocates
say cannabis could be
a source of treatments
...
Hundreds of multiple sclerosis sufferers in the UK are already
being treated with cannabis-based medicines in clinical trials
funded by the Medical Research Council (MRC).
Ministers
are also looking at the possibility of using them for post-operative
pain relief and have promised to recommend that the Medicines
Control Agency licenses the treatments if the success of earlier
experiments is repeated.
...
Drug companies have isolated the active ingredients in cannabis
and made them available in the form of a pill or a spray.
Neither
gives a "high" - but some patients say the pills make
them nauseous.
Cannabis
has long been favoured by many MS and cancer sufferers for its
pain-relieving properties. They
say it also stimulates their appetite without the unpleasant
side effects of many alternatives currently available on prescription.
...
Supporters of medical marijuana say the drug can prevent nausea
caused by cancer chemotherapy, alleviate muscle spasms from
multiple sclerosis, relieve chronic pain and help in the treatment
of anorexia, glaucoma, epilepsy and mood disorders.
Opponents
say it damages the ability to concentrate and can have other
harmful side effects.
Though
several countries allow medical use of marijuana, only Canada
licenses patients to grow and possess it.
...
Marijuana is a Class B drug in Britain, and possession is punishable
by up to five years in jail. The government has said it intends
to reclassify it as Class C, meaning that possession, though still
illegal, would not be an arrestable offense.

Facing
Your Genetic
Destiny (sections regarding diabetes)
Monday,
February 18, 2002

Excerpts
from article
detailing the ways in which genetic testing may impact both
diseased and otherwise healthy individuals, as well as information
regarding the genetic causality of diseases:
-
- - begin excerpts - - -
...
The use of predictive gene tests is still limited to a handful
of relatively rare and highly hereditary diseases.
But
that scenario is about to change: scientists in academic and
corporate laboratories are tirelessly digging through human
DNA to find genetic variations that make individuals susceptible
to common diseases, including
Alzheimer’s, cancer, cardiovascular diseases, diabetes
and stroke.
| Risky
Antigens
Humans
with HLA variants "DR 3 and DR 4" have a 15
times greater risk of getting juvenile diabetes.
|
...
certain HLA flavors were often associated with inflammatory
and autoimmune diseases, such as juvenile diabetes or rheumatoid
arthritis (see chart).
...
subsequent studies on twins and families have revealed strong
hereditary components to virtually all common disorders -- from
diabetes, asthma, hypertension and cancer to many mental disorders,
including depression, schizophrenia and autism.
...
Geneticists distinguish between monogenic disorders --in which
a single gene rules as an absolute master-- and multifactorial
disorders.
The
latter result from "criminal gangs" of genes --often
tens of them-- and the influence of environmental variables,
such as diet and smoking habits, as well as infections or contact
with toxic agents.
Thousands
of known monogenic diseases, such as cystic fibrosis, muscular
dystrophies and retinitis pigmentosa, are caused by single defective
genes and are inherited in a predictable way.
...
But most common disorders are instead multifactorial. Individual
genetic variations may render someone susceptible, but they
are neither necessary nor sufficient to cause such a disease.
People
with a genetic tendency toward diabetes, for example, have an
increased statistical chance of being affected one day but are
also likely to live in good health to a ripe old age.
On
the other hand, people without any evident predisposition may
become diabetics, against all odds.
Therefore,
genetic tests for multifactorial disorders give only an estimated
risk; they will never indicate whether the disease will actually
develop.
| Twin
Studies
Probability
that both identical twins are affected by
Juvenile
(insulin-dependent) diabetes - 53 %
Non-insulin dependent diabetes - 40 to 80 %
Probability that both fraternal twins are affected by
Juvenile
(insulin-dependent) diabetes - 11 %
Non-insulin dependent diabetes - 10 to 40 %
|
| Boomerang
or Not?
The
following common disorders come with varying degrees of
genetic risk. That risk, if it is known, can sometimes
be lessened through preventive measures. Other times,
it cannot. In these cases, the results of a genetic test
can, like a boomerang, lead
nowhere and so their value is questionable.
...
NON
INSULIN-DEPENDENT (TYPE 2) DIABETES
Affects one in 10 people older than age 65.
Genetic risk - Researchers have recently identified variants
of a susceptibility gene in chromosome 2 (CAPN10). Another
10 regions of the genome are associated with the disorder.
Prevention - Sports, diet, smoking cessation
- - - - - - - - - - - - - - - - - - - - - - - -
INSULIN DEPENDENT (TYPE 1 OR JUVENILE) DIABETES
Autoimmune disease. Affects one to three in 1,000 people
under the age of 20.
Genetic risk - HLA variants DR3 and DR4 increase the risk
15-fold. Another 15 regions in the genome probably contain
predisposing genes.
Prevention - No prevention is currently available
|
... experts
agree that the utility of a predictive test depends on the possibility
of an effective prevention.
Most likely,
a growing number of diseases will be preventable in the future
with drugs, vaccines, or gene therapies and stem cell transplants.
When that
happens, many predictive tests, which now are useless and even
dangerous, will become powerful tools for helping us to secure
our health.

Hubble
Capabilities to be Enhanced Tenfold
Monday,
February 18, 2002

Excerpts
from article
describing a Hubble Space Telescope upgrade which will dramatically
expand its capabilities:
-
- - begin excerpts - - -
NASA’s
fourth servicing mission for the Hubble Space Telescope, scheduled
to lift off on Space Shuttle Columbia on February 28, will give
the orbital observatory a series of midlife upgrades that includes
the Advanced Camera for Surveys (ACS), a new instrument package
that will increase Hubble’s already formidable capacity
for discoveries tenfold, according to the leader of the team
that built it.
“If
you had two fireflies 6 feet apart in Tokyo, Hubble’s vision
with ACS will be so fine that it will will be able to tell from
Washington, D.C., that they were two different fireflies instead
of one.”
...
there’s an outside chance that the ACS might even be powerful
enough to obtain “direct evidence” -- i.e., an image
of some type -- of planets in other, nearby solar systems. Although
planets have been detected around many stars, all of them have
been inferred through the gravitational wobbles they impart
to their stars, rather than detected through a direct image
of the planets themselves.
...
All the ACS instruments take advantage of new techniques and
technology developed since Hubble’s inception to deliver
increased observing power at greatly reduced costs. In
comparison to the Wide Field Camera II, another instrument already
in use in Hubble, the ACS will provide two times the observational
area, two times the resolution, and four times the sensitivity.
