Difficult = better ?
Why do things the hard way ? Because sometimes the hard way can make you
fitter apparently – as shown in a new study by scientists at the Oregon
Research Institute (ORI).
A group of 108 ‘physically inactive’ senior citizens ( the oldest
was 92 ) were persuaded to walk on uneven ‘Chinese cobblestone’ mats
for an hour, three times a week. The specially made mats were moulded to
replicate the riverstone cobble paving commonly found in Chinese parks and
gardens. Regular walking, and even dancing on the cobblestones is seen as
a health-enhancing activity in many parts of China.
At the end of 16 weeks, the researchers found a marked difference in the
health of the cobblestone walkers as opposed to ordinary ( flat ) walkers.
They had lower blood pressure, and ( not surprisingly perhaps ) their balancing
skills had improved.
The research will be published in the August
issue of the Journal of the American Geriatrics Society.
If you’d like to experiment with some considerably more-awkward-than-usual
walking in your own home, you can get hold of a replica Chinese cobblestone
mat, we’re told, from the Oregon Research Institute – though
we could find no details about them on their
website.

Sun of JET
Yesterday, news agencies across the world announced that a decision had
finally been reached about where to build the International Thermonuclear
Experimental Reactor (ITER).
http://www.jet.efda.org
The new device will have “ striking design similarities “ to
the existing Joint European Torus (JET) – the experimental
fusion reactor at Culham, Oxfordshire.
But it will be considerably bigger.
The JET reactor has so far managed to generate 16MW (16 million watts) “ a
value comparable to the power needed for heating one thousand households
in a cold winter.” Says their
website.
They might have added - “ for just a few seconds “ - because
the reaction is not sustainable for any longer. It also needs “ a
value comparable to the power needed for heating one thousand households
in a cold winter ” of power input, to get the machine
going. For it consumes more than it generates.
Nonetheless, JET has provided an enormous amount of know-how – and
also proved ( like CERN ) that large-scale international scientific co-operation
is viable. But what about fusion itself ? Is that viable ?
There is a lot of testing to do. The plasma core of the reactor will reach
100 million °C, and, needless to say, there is no known material which
can withstand that kind of temperature. So, the reactors have to operate
in short pulses of a few seconds, and even then, choosing the material with
which to line the doughnut-shaped reaction chamber is very problematic. (
the new ITER machine will use beryllium - JET tried carbon composites and
found them unsuitable )
Although the technology behind the reactors is astonishingly sophisticated, the fundamental
trade-off is simple :
If the reactor is bigger, heat doesn’t leak out as fast – so
it can maintain the fusion longer – unfortunately, the lining of the
fusion chamber is more likely to melt . . .
So, is it going to work ? There are some very high-profile doubters. Just
three years ago, calculations by US fusion theorists allegedly raised " grave
doubts " that ITER could achieve ignition. ( source : New
Scientist, February 2002 )
Although research has been going on for fifty years, the truth is that no-one
is yet certain that the machine will be viable. A ‘never published’ report
by the UK government was leaked to New
Scientist in July 2002 - Here’s some quotes :
"The safety and environmental advantages of fusion are
far from clear-cut."
"Fusion reactors will still produce large quantities
of radioactive waste."
"A technically viable solution may not ultimately be
achievable."
Oooops . . .
In short, ITER is a $13Billion experiment. It might work. It might not.
A $13Billion international research effort into producing, say, ultra-efficient
photovoltaic solar panels, or tidal power generators, would be far more assured
of success – but such projects wouldn’t be able to claim the “ akin
to building a star on Earth “ headlines.
Arthur C. Clarke made one of his astoundingly farsighted observations
when he pointed out that, sometime in the future, a spacecraft, on a deep-space
exploration voyage, will almost certainly be overtaken by a newer craft -
launched some years later - which can travel much faster.
In other words, it could be argued that it’s wiser to wait until technology
is 100% worked-out before one starts constructing something very costly.
On the other hand, if we did that, no large-scale experimental projects would
ever get built.

PFI Fryup
Really Magazine likes to keep our eye on all things scientific
and technological, and the flow of large amounts of money – in our
book at least – is a ‘systems’ issue.
Some examples of huge flows of cash ? £Billions in fact ? The UK government
has been bending over backwards for some years now to try to get Private
Finance Initiatives ( PFI’s ) off the ground.
PFI’s involve the government raising money by ‘borrowing it’ from
third party firms ( rather than directly from banks ).
But, of course, the government can command very low rates of interest from
the banks themselves – they have, after all, first class securities
- so why not borrow directly and cut out the ( expensive) middleman ?
There’s a helluva lot of explaining to do - to which we very much
look forward . . .
George Monbiot ’s piece in today’s Guardian doesn’t
explain why the government is so keen on the idea – but he
presents an almost unbelievable list of the disasters clocked-up so far.
If you're a UK taxpayer - read
it - and see where your money's flowing to.
If you’re a high-ranking government official in a country other than
the UK, and you’re considering importing the PFI concept to your economy – read
it – then file it under ‘Dogs’ ( subsection ‘Breakfast’ )
The scale is mind-boggling.

Solar Sails ( into the sunset )
It’s a shame that the Cosmos-1 ‘solar sailing’ spacecraft,
with its mirror-finish Mylar™ sails, never
made it into orbit.
Because now we’ll have to wait a few years to find out if it would
have worked.
The theory is old. Newton wondered if light might exert a pressure,
and James Clerk Maxwell predicted the effect in 1873.
But the idea of ‘ Solar Sails ’ as a means of propelling spacecraft,
took until 1951 to appear - in an article entitled “Clipper Ships
of Space” from “Astounding Science Fiction” magazine.
( source: www.technovelgy.com )
Experimental evidence leaves no doubt whatever that light can exert a pressure – but
how exactly ? Photons have no mass . . . if a photon bounces off
a mirror - so what ?
Luckily, we’re not the only ones to find the traditional explanations
of ‘momentum transfer’ less than 100% convincing. So does Thomas
Gold, Professor Emeritus of Astronomy at Cornell.
In a 2003 paper entitled “ The
solar sail and the mirror “ he says why ( he believes
) the sails won’t work. As he bluntly puts it : “ The
proposed solar sail cannot be accelerated by sunlight. “
He goes on to explain though, that if they were black, instead of mirror
finish, they might just work . . .
It’s
all a very reminiscent of the arguments which are still going on as to how Crookes’s
Radiometers work. ( Despite what you may find in the textbooks, the jury's
still out - but Einstein may have explained it ).
Confused yet ? We certainly are. But we may know before too long. We have
a hunch that the Planetary
Society will be launching Cosmos-2 before very long.

A fresh look at bad air
A couple of weeks ago we published a link to a new service which gives London
residents access to air pollution forecasts.
http://www.cerc.co.uk/YourAir/
( it’s already seen NO2 levels hit
the red mark )
But, according to government guidelines “ People
spend more than 80% of their lives indoors.” ( We’re
guessing they’re not including farmers and golf coaches )
So what about indoor air pollution ?
Over the years, a great deal of research has been undertaken into the subject.
And various reports have been ‘published‘ . . . There is just
a chance though, that you might not have been informed . . .
See:
http://www.advisorybodies.doh.gov.uk
“ These reports show that concentrations of air pollutants
that frequently occur indoors can have an adverse effect on health. “
To the rescue : Essex University. On Wednesday, they’re unveiling
in London a new software suite designed to aid local, regional and national
governments with a system to translate measured outdoor pollution concentrations
into real health risks.
See:
http://www.essex.ac.uk
It’s called the Urban Exposure Module, and plugs into the Air
Quality Management System (AirQUIS)
already in use across the globe.
The new software predicts indoor pollution using a set of models which utilise
the prevailing outdoor figures ( plus some added-in indoor data such as the
levels of chloroform in drinking water . . . don’t
ask )

been piloted in Norway ) see :

Not to be sniffed at.
‘Opal ™’ is
the name of BP’s new low-aromatic gasoline. It’s just arrived
at the pumps, and is “ Unique to Australia - A
safer petrol for remote communities ”
The fuel is produced, with financial support from the Australian Government,
at the BP Refinery Kwinana – and it's designed to combat ‘petrol
sniffing’ - which has become a severe problem in some parts of the
country.
Sniffing a highly dangerous ( though by no means new ) habit, and can cause
permanent brain damage.
“ We don’t suggest that this fuel will
address the huge issues (eg boredom, unemployment ) that form part of the
reasons why many young people sniff petrol “ says the website.
The new fuel carries only one fifth of the level of ‘aromatics’ that
ordinary gasoline does. And so it should be less attractive to 'sniffers'.
But the company's ‘ Material
Safety Data Sheet ' still quantifies the product’s odour as “ strong ” .
. .
( And it’s still classified as a Category 1 carcinogen )
But then, as the ‘Opal™’ website says “ All
fuels are potentially toxic ” . . .
It’s an interesting observation – and we haven’t been
able to think of one which isn’t ( except, maybe this
one . . . )

If you live in the US, those are the lifetime odds against being struck
by lightning.
OK, it’s a little late, we admit, but we bring you the news that this
week is (still) Lightning
Awareness Week. . .
Every year more than 60 people are killed by lightning strikes in the US – and
the National Oceanic and Atmospheric Association ( NOAA ) is not
standing idly by – they’re doing something about it
By issuing guidelines on how to avoid being struck. As their site says - “ Lightning
Discharge: Don't Be a Part of It “
There are estimated to be around 25 Million cloud-to-ground (CG) lightning
strikes in the US every year. But, unfortunately “ Few
people really understand the dangers of lightning. Many people don't act
promptly to protect their lives “
So, what should we do ? “ The rule is - If thunder
roars, go indoors "
“ When
you see lightning, count the time until you hear thunder. If that time
is 30 seconds or less, the thunderstorm is within 6 miles of you and is
dangerous. Seek shelter immediately “. . .
You should then remain inside until 30 minutes after you hear the last peal
of thunder. The shelter should be fully enclosed, and substantially constructed,
with wiring and plumbing in the walls.
Whilst inside, you should stay away from doors and windows – and “ avoid
contact with anything that conducts electricity ” ( does that
include other people ? We're not sure )
Lightning travels at about one-third lightspeed and carries 10,000 times
the power of a household electrical circuit. So, if you do get hit, the bolt
will probably do a quite a bit of damage.
The NOAA site goes into some detail about what medical effects to expect
if someone is unlucky enough to get struck. Survivors often suffer from frontal
lobe damage, intense headaches, and seizures - which can still happen months
after the injury.
“ The four most important factors in overcoming disability
from lightning injury (or from any illness or major injury for that matter)
are:
1) Supportive family/friends network.
2) Becoming your own advocate and learning as much as you can about this disability.
3) A physician willing to listen, read, learn and work with the survivor and
their family.
4) A sense of humor. “

story from Mark Twain - ( it's been on the www since 1870 )

537 to 1
If you had to come up with one word to describe the UK city of Winchester,
it might be ‘genteel’ or ‘affluent’ or, as the official
tourism site says, “unspoilt ”.
Set on the edge of the rolling ‘South Downs’ ( soft chalk hills
), it has a history which goes back more or less 1000 years - it used to
be the Capital City of England.
Nowadays it’s an affluent place, attracting hundreds of thousands
of visitors every year. Olde Tea Shoppes, a pedestrianised highstreet, and
trout streams running through the centre of town (see photo). It boasts near
zero unemployment, and, amongst its residents, you’ll find judges,
lawyers, academics, and (now) world-famous TV journos.
Not,
perhaps, the first place to spring to mind if you were thinking of getting
rid of 2 Million cubic metres of nuclear waste.
And yet it appears on a previously secret list of 537 possible dumps repositories – just
published - which the UK government was considering between 1987 and 1991.
Putting it bluntly, the authorities would have had as much chance getting
the idea past the local über-NIMBY residents as they would have had
building a new nuclear plant out of egg-boxes and chewing gum.
So, wisely, it was rejected in the first round of site reviews – along
with the (almost) equally touristic Abingdon, Kenilworth, and Dartmoor.
The next rounds discounted Grantham, Chester, the island of Raasay in
Scotland, and dozens more.
By that time, the powers-that-be had all but given up the idea of finding
a location which was geologically suitable – preferring instead sites
where there would be minimal local opposition from residents.
“ We are doubtful whether, given the expected level
of opposition, it would prove possible to pursue to a successful conclusion
a site where there is no measure of support in the local community - no matter
how good its technical features “
The list of sites was eventually whittled down from 537 to 1 , and, by a
breathtaking coincidence, the perfect location turned out to be none other
than Sellafield – just a stone’s throw from Calder
Hall ( the site of the UK’s first nuclear reactor, built to
manufacture plutonium for nuclear weapons ) . . .
Now spin forward to 1997. . .
When, unhelpfully, the local geology was found to be unsuitable - and the
whole plan was scrapped.
Back to the drawing board(room).
The present situation is that the waste* - which will remain dangerously
radioactive for thousands of years - is in temporary storage “ at
34 locations around the UK “ ( where ? we don't know - there
are no details in the new publication ) .
As we reported last
month, if you have any ideas of how to safely dispose of the stuff, then
the government’s Committee on Radioactive Waste Management (CoRWM)
would urgently love to hear from you.
“ Have your say on the UK's Radioactive Waste
- and help us find a way forward “ . . . P L E A S E . . .
( Do bear in mind though that they have already officially discounted the
idea of burying it under polar icecaps, or shooting into space )

not to deal with nuclear waste ” 18

Tomorrow’s temp will be - errrr . . . the same as always. (?)
Given the current interest in Global Warming, we propose that TV and Newspaper
weather forecasts should begin giving ‘Global’ temperature forecasts
every day ( just average all the forecasts for cities across the world ).
Does the mean world temperature fluctuate on a regular basis, or do the
winter/summer - day/night - North/South averages just pan out the same every
24Hrs ? We have no idea.
Perhaps someone is doing it already ? If anyone knows of a site, can you let
us know please ?

Slight lack of lunar goalposts
A quarter of a million dollars is a lot of money – and it’s
up for grabs courtesy of NASA, who are offering the prize to “ the
first team that can extract breathable oxygen from simulated lunar soil before
June 1, 2008.”
The Moon Regolith Oxygen (MoonROx) challenge was announced
in a press-release on
May 19th, and was widely covered in the media, with an excellent explanatory
article in New
Scientist ( 28th May 2005 )
Why the prize ? According to Brant Sponberg, NASA's Centennial
Challenges program manager - “ The innovations
from this competition will help support long-duration, human and robotic
exploration of the moon and other worlds,"
So, let’s get down to details. Exactly what is required of the team
? They must develop hardware ( within mass and power limits ) that can extract
at least five kilograms of breathable oxygen from simulated lunar soil (called JSC-1)
during an eight-hour period.
Keen to get started ? You might have to hold off for a while – there
are rules for “ eligibility “ – and,
of course, you’ll need to know what the ‘mass and power limits’ are.
There may be other regulations too – unfortunately we can’t
enlighten our readers – because the rules still haven’t been
published . . .
Here’s what the Florida Space Research Institute says :
“ FSRI and NASA are now working on a detailed package
of rules to govern the competition, including eligibility requirements. We
will release a news announcement when the rules are complete and will post
them on this site. Please visit again to check availability. “
We
have checked – and, more than a month after the original announcement,
they’re still not available. ( unless we missed them )
Errrrr . . . Wouldn’t it have been a good idea to set the rules before announcing
the completion ?

Monkey business
“ We show that standard price theory does a remarkably
good job of describing capuchin purchasing behavior “
So begins the abstract of a new study from Yale ( School of Management
)
No, it has nothing to do with the price of frothy coffee, it’s referring
to Capuchin monkeys, and the fact that, with regard to financial dealings
at least “ Capuchin monkeys look remarkably like
us; making rational decisions in many of the same settings that humans get
right, but also make many of the same mistakes we make. “
The
experiment was a complicated one, in which the subjects learned to trade ‘small
metal disks’ ( sound familiar ? ) for food rewards.
Analysis of the results showed that “ they adjust
their purchasing behavior in ways consistent with the Generalized Axiom
of Revealed Preferences (GARP).”
If we can partially decode that - the little monkeys were more interested
in ‘avoiding loss’ than they were in ‘making gains’.
Indicating, as the study’s conclusion cites “ loss-averse
behavior is not confined to humans “
The University’s press-release puts an interesting tag to the story
by saying “ [The] work provides an evolutionary
spin on the current debate about why Americans do not save enough for retirement
or put enough of their savings into the stock market. “
Not putting enough of their savings into the stock market ? ? ?
Now where did we hear that idea before . . . Oh yeah, former
Yale alumnus G. Dubbya – who is, of course, currently trying
to persuade his public to do just that . . .

Holiday perils
The ‘Holiday Season’ is upon us ( apparently ). So, here’s
a couple of vacation-related unversity press-releases which our readers may
find helpful . . .
Firstly, be careful what you eat on holiday – especially in restaurants. “ Beware
of the breadbasket “ is one of the top ten traveler’s
tips from Louisiana State University.
While you're at it, why not split an entrée in half ? “ You
are keeping yourself from overeating as well as cutting calories in half. “
Can't argue with that can you ?
see:
http://www.pbrc.edu/pressArticle

Next, consider what happens when you get back . . . You could end up suffering
from Post-Traumatic Vacation Disorder (PTVD). “ [
Holidays ] should be a time to rejuvenate. But many people return from vacation
to face piles of work and hundreds of emails “ says a clinical
psychologist from the University of Alabama at Birmingham.
The trick, apparently, is to wrap up as much work as possible before you
leave . . .

Security in Iraq is today just a bad as it was after the removal fall of
Saddam, admits US Defence Secretary Donald Rumsfeld.
But things can always be worse than they are - as the secretary pointed
out in a BBC

a rare example of a positive double-negative ? ) -
"A lot of bad things that could have happened have not
happened."
That’s undeniably true ( as it is of anywhere in the world - at any
time ).
Puzzling, perhaps, that he didn’t mention one of the things which
really has changed beyond all recognition.

Mr. Average Male UK Adult now owes the credit suppliers £5000, and

New central London air quality service.
Caution : Acronym Overload (AO) ahead.
Somehow managing to cram CERC, PROMOTE, AirTEXT, GMES, GSE and NILU into
their short press
release , the ESA ( European Space Agency ) is announcing a
new service to help asthma sufferers ( and others ) keep track of air pollution
in central London.
The service – called ' YourAir ' – will send phone
and text messages to ‘vulnerable individuals ‘, predicting levels
of nitrogen dioxide, ozone and airborne particles (PM10's), as well as indicating
what they are calling the ‘ Health Index ’.
There’s also a new website with the predictions :
http://www.cerc.co.uk/YourAir/
So, we can see that the central London PM10 levels for tomorrow ( 18th June
) are around '30-40 ug/m' (sic. - they mean µg/m3 ) – categorised
as ‘low’
Oddly, neither the press release, nor the YourAir site, go into any hard
detail about the very real dangers of air pollution.
“ Everyone knows how smoky air can make you cough
and cause your eyes to water. - YourAir for Central London shows you the
levels of the three most important pollutants in Central London: ozone,
airborne particles and nitrogen dioxide. All three of these are thought
to harm people who have asthma or other respitory (sic.) or
cardiovascular problems. At very high levels they can harm healthy people
too. “
“ Thought to harm “ ? ? ? The words 'get' and 'real'
spring to mind . . .
It’s very hard to get any down-to-earth figures for the number of ‘excess
deaths’ in the UK caused by air pollution. The most concrete estimate
we found was so far was ‘a few thousand ’
If we look a few hundred kilometers away though, the German government is
not nearly so shy about putting a figure on it. The number of ‘excess
deaths‘ caused by air pollution in Germany is now officially 60,000
per year.
If we were to scale the figure to take account of the smaller UK population – then
we can guess that around 40,000 or so UK residents are currently dying each
year from the effects of breathing bad air . . . ( not including smokers
of course )
Perhaps the figures are buried in the UK Government's Department
of Health website somewhere – but we couldn’t find
them – if anyone manages, please let
us know.

As we reported back in Oct 2004, a study at Cornell University showed
that " The more food we served to the college-student
volunteers in our eating study, the more they ate “
http://www.news.cornell.edu/releases
Now, the same uni has performed another study, but this time with a ( rather
small ) sample of schoolchildren.
http://www.news.cornell.edu/stories
The professor of nutritional sciences and psychology at Cornell, David
Levitsky, says " We found that portion size
is, by far, the most important factor in predicting how much a child will
eat.”
He also reveals that " - the more snacks children
are offered, the greater their total daily food and calorie intake."

Full-body x-ray machine.
It’s been around for a while now, but a full-body x-ray setup – called Statscan – is
in the news again. The company which manufactures the scanner have just launched
the machine in Europe.
See: http://allafrica.com/stories/
Due to radiation concerns, full-body x-rays are not normally performed except
in major trauma emergencies, but the Statscan machine works at very
low dosage – 1 mGy – roughly the same as a conventional chest
x-ray.
You might not guess from the manufacturer’s website http://www.lodox.com that
a major shareholder in the company is (or at least was*) De Beers (
the world's largest diamond consortium ).
In fact, they were responsible for the original design of the machine back
in the 1990’s . . .
You may be wondering, as we did, why a diamond company would develop a full-body
x-ray machine ?
Think : ‘body cavities’ + pilfering
* * *
There is, however, no such thing as a 'risk-free' x-ray dose - so, non-medical,
non-emergency, uses would certainly not be encouraged - making this
2002 report from the online South African tech mag Dataweek somewhat
disturbing.
Here's a quote from the piece :
“ [ the scanner ] is in operation at many of the De
Beers diamond mines. The person standing inside the X-ray cubicle can be
scanned in some 12 seconds after which they are transferred either to the
outside or a booth where they stay while security personnel can carefully

Son of Concorde.
Concorde was a ‘commercial disaster’ – although
the usual meaning of the word ‘commercial ‘ has to be modified
slightly - since the bulk of the money which was lost came from taxpayers
rather than the world of commerce.
On a good day, it flew half empty.
Its engines were extremely noisy ( perhaps the noisiest passenger aircraft
ever built ), and the fuel costs were sky high.
Now, a new agreement, signed yesterday at the Paris Air Show, will
involve European and Japanese companies in a new project to build ‘ Son
of Concorde ’
It’s being very
widely reported in the news-sphere - but not one of the reports we
have seen ( so far ) has mentioned the real reason why the original
project failed.
Shortly after it started test flights, it was banned from supersonic speeds
in the airspace of all countries which it flew over. Not surprisingly, given
the appalling ‘sonic booms’ it created.
So, it could never fly at the speeds for which it was designed over any
populated territories – just over the sea – which was why the
sole route ended up being London/New York – straight over
the Atlantic ( though it had to slow down to sub-sonic at either end ).
Is the new consortium hoping to find a novel technological way of bending
the laws of physics to avoid the ‘sonic booms’ - which every
faster-than-sound aircraft creates ?
If it ever gets built, it might cut the flight time from Iwo Jima to Galapagos by
several hours.

Not Our Problem
A very informative and clear article in the Wall
Street Journal tells
us what Exxon ( the most profitable oil company in the world
) thinks about global warming.
According to the Journal, Exxon is far from convinced that the use of fossil
fuels is the main cause of global warming.
" We're not playing the issue " says Lee
Raymond, Exxon's chairman and chief executive.
Of course there’s absolutely no disputing the fact that the burning
of fossil fuels releases CO2 into the atmosphere.
It has to. The carbon locked up in the oil has to go somewhere. It used to
be underground – now it’s up here.
So, we can only presume that Exxon is simply questioning the notion that
the CO2 released when their oil is burnt
is significant in terms of its global warming potential.
Of course they have the right to disagree with the vast majority of climate
scientists - who might all be wrong in the assumption that burning gargantuan
and unregulated quantities of fossil fuels is generally a ‘ bad idea ‘ .
Time will tell who’s right. When the time arrives, one party or the
other will have a hell of a lot of explaining to do.
Here’s a prediction. The jury will finally reach their verdict just
as the last drops of oil run out.

RLS
It’s defined as ‘ a disruptive neurological disorder characterized
by a compelling urge to move the legs ‘ .
Restless Leg Syndrome is more common than previously thought. A
new international study ( the first of its kind ) has found that approximately
7% of the population suffer from it. The causes, unfortunately, remain unknown.

Raising eyebows ?
One of the most poisonous substances known to man – botulism toxin – is
now routinely used to treat neurological disorders ( famous too, of course,
for its cosmetic applications ).
Now, another extreme toxin – the chemical responsible for the lethal
symptoms of tetanus – may have a future in medicine.
New research from the Institute of Neuroscience at the Universitat
Autònoma de Barcelona, has identified ( a component of ) the
substance as an extremely potent serotonin inhibitor.
Serotonin inhibitors ( the most famous being Prozac™ )

"New Balls please."
The mechanical engineering dept at Bath University has press-released
details of a new technique to help prevent tennis balls losing their bounce.
Aside from providing a less-than-perfect game, the team point out that “ Playing
with flat balls can increase the likelihood of tennis elbow “.
The new invention - named ‘ Pump’n’Bounce ‘ -
is a hand-operated pressure chamber which can encourage the balls to regain
some of their sprightliness.
“ Initial tests have shown that it is possible to double
if not treble the lifetime of a tennis ball using this kind of system.”
Sadly though, given the way the ‘consumer society’ works, we
can’t help thinking that tennis ball manufactures may not be bouncing
up and down at the news . . .

Our Brain has gone blue . . .
The carefully ( as always ) worded New
Scientist article doesn’t actually say that “ The ‘ Blue
Brain Project ' would be the first computer simulation of the entire
human brain " . . . they’re obviously aware that that would
be pure fantasy.
The ‘ BlueBrainProject ’ (BBP)
is a joint venture between IBM ( hence the Blue ) and the Swiss
Federal Institute of Technology (EPFL). It will use a purpose-built
supercomputer to construct “ an
accurate software replica of the neocortical column within 2-3 years “.
Quite a challenge, to say the least.
The BBP website goes on to say that they will be able to model “ -
progressively large brain regions and eventually the whole brain “.
Keyword = Eventually.
Bearing in mind that, as far as we know, the human brain is by far the most
complex organised structure in the universe, ‘eventually’ might
be quite a long time in arriving .
[ Number of neurons in a human brain is around
100 Billion.
Each neuron typically has is 1000 to 10,000 connections
to others.
Modeling that lot in a few boxes of hardware ?
You do the maths. ]
If our back-of-the-envelope calculations are correct, the current effort
would have to be around 10Trillion times bigger to have any hope
of getting near the whole-brain target.
We’d like to show you more about the project – but this is what
we got when we tried to access the press-release from
IBM . . .

We can’t help thinking that a company having difficulty in getting
a simple website to work consistently may find modeling an entire human brain
somewhat problematic.

Flocking Intelligent WebServers
Researchers at the University of Essex ( Department of Electronic
Systems Engineering ) have succeeded in making a ‘flying webserver’,
weighing only 76grams, which managed to stay aloft for three minutes.
The Linux sever-software runs on a miniature ' Gumstix ’ computer
fitted to a toy helicopter ( a Proxflyer
Bladerunner ), and communicates to another PC via Bluetooth™.
The project is called ‘ UltraSwarm ’, and is aiming
towards a so-called ‘swarm’ system of airborne flexible computing.
A
paper describing the system has just been presented at the IEEE
Swarm Intelligence Symposium in Pasadena, California.
Impressive as the project is, you might find yourself asking . . .
Why ?
We can’t answer that for you – but you could try contacting Lockheed
Martin Aerospace ( who are providing ‘technical assistance’ ).
Perhaps they'd like to make a miniature swarming version of their " Sentinel
of Peace " or their “ All-In-One
Dispenser ”?

Ichthyological risk-assessments ( Elasmobranchs )
The director of the International Shark Attack Files is not happy.
After the 1975 film ‘Jaws ’ :
“ Shark fishing became a popular blue-collar
recreational fishing activity for testosterone-bolstered males “
says the press release. Ouch !
In the post ‘Jaws’ years, overfishing has caused the numbers
of some species of shark in the waters off the U.S. eastern seaboard to fall
by as much as 90 percent.
The International
Shark Attack Files site, run from the Florida Museum of
Natural History, is keen to help out with some positive shark-centric
PR – aiming to counteract their unnecessarily negative image, and
so help protect them for future generations.
So, for instance, we can learn that in 1981, more people in New York were
bitten by horses (18), than by sharks in the whole of the US (12)
To further put the risks into perspective, the stats tell us that between
1953 and 2003, 101 unfortunate people died in Alabama as a result of lightning
strikes – whilst the number perishing from shark bites was 0.

Spend ( like it or not )
The Stockholm International Peace Research Institute (SIPRI)
have just released their yearly report into arms trading. The figure for
2004 global expenditure on arms clocks-in
at around $1Trillion.
SIPRI point out that this equates to a spend of $162 for each person alive.
The figure isn’t wrong. But, if we may say so,it's highly misleading.
They’re simply dividing the $1Trillion by the number of people on
the planet – and, of course, not everybody would be able to contribute
to the arms spend – even if they wanted to.
We’d like to do our own back-of-the-envelope check to adjust the figures
to try to get a handle on the kind of amount that ‘working people’ -
the ones who are paying for the arms via their taxes – might be spending.
Firstly, let’s rule out the children – making up say, 20% of
the population. Then there are senior citizens – say another 20%. Then
the non-waged, perhaps another 20%.
At a very rough guess, we can at least double the $162 - to $324.
But this would not differentiate between the cash available from, say, a
factory worker in Germany, and another in China – where the monthly
wage might be $36 - smaller by a factor of around 50.
So, to guestimate what ‘Western’ workers might be spending – we
can at least double the figure again. Perhaps $600.
But, they are taxed on their earnings at around 45%. So let’s say
they'll need to earn $1000 to pay the bill.
The SIPRI figure is, however, only taking in to account the cash spent on hardware.
It's only half the story. It isn’t measuring the equally vast sums
used to maintain the personnel and the infrastructure of the system which
will be utilising the arms.
To take this into account we’d have to at least double the figure
again.
Our highly unscientific guess is that our average ( wage–earning )
reader is probably spending the equivalent of $2000 ( ish
) per year to keep the ‘ Military Industrial Complex ‘ in the
manner to which it has become accustomed. ( still seems a bit low to us )
Happy with your contribution ?

Ooops ! we forgot that the figures might be affected depending on the gender
of the worker. In fact, we’re not sure that they even seem to be able
to agree exactly what arms are. See :

Do you have a HAL ?
Asks the Tsukuba University. They aren’t referring to an
uber-conscious computer ( as in 2001 ) or even a ‘ Hardware
Abstraction Layer ’ ( as in PC architecture ) , but to a '
Hybrid Assistive Leg ' instead.
The HAL is a new variation on the idea of a powered ‘exoskeleton’ – a
concept which re-surfaces in the tech-news-sphere on a fairly regular basis.
( the first official attempt was by General Electric 40 years ago
)
Unlike some previous efforts though, this one seems to work pretty well,
and has just been demo-ed at a press conference at the ongoing World
Expo2005 in Japan.
It has muscle sensors and position sensors to allow it to add power to the
stride, and was originally developed to assist people with ‘gait disorders’.
But the media has already picked up on the idea that it may be the precursor
of a viable super-strong Cybersuit.
In the past, the main stumbling block with development of the 'exoskeleton
idea' has been a worry over what happens if/when the system malfunctions.
Maybe the Tsukuba University has cracked it.
You can see videos of HAL in action here :

Marks out of 101001001110100
‘ Plagiarism ’ is
now a major problem with regard to student projects – from the school
classroom, right up to Phd level. Why bother to write something original
when you can grab it from the WWW with a Ctrl+V ?
Over the last few years, several pieces of software have appeared which
can analyse essays and detect cut’n’paste – with
varying reliability.
But now lectures [ will soon ] have a new tool in their toolbox. Software
which can mark the essays for style and content as well. Essays ( which currently
have to be in Word™ format ) are uploaded into the software
suite with a small hand-marked ‘tuning’ sample.
According to the originator of the project, Dr. James Christie of
the Robert Gordon University, Aberdeen, the new software – called SEAR (
we haven’t been able to decode the acronym ) will free-up time for
lecturers “ to give better constructed feedback
or to undertake other lecturer related activities “
* * *
We can’t help noticing that there’s an interesting reductio
ad absurdum on the horizon. Since it’s now possible for canny
students to generate
their essays with little ( or no ) input of their own – and it’s
also possible for a computer to mark the results – why bother with
the ‘wetware’ at all ?
Couldn’t we cut the students and lecturers out of the loop completely
? . . .
Resistance is futile : You will be assimilated.

The road to Immersipresence.
Not all that many people can play a musical instrument, but quite a few
can drive a car. That’s the cornerstone tenet of the Expression
Synthesis Project (ESP) from the University of Southern California (USC).
Their new interface, configured like a car’s controls “ allows
everyone a chance to experience what it’s like to perform. It lets
them appreciate the decisions made by a musician in interpreting the music.”
As you might expect, the device controls the synthesised music via MIDI
- but it's also coupled with “ François'
Software Framework Architecture for Immersipresence and Modular Flow Scheduling
Middleware “ ( don’t
ask us )
The music rolls out, and a virtual ‘road’ is displayed on a
monitor, “ The road’s turns suggest to the
driver when to slow down and speed up."
We can’t quite figure out what role the steering wheel plays, but the
foot pedals control the tempo of the piece.
For an overview, see :

Midsummer Night's ( Swiss ) Dream
There can’t be all that many hormones which have their own website. Oxytocin is
one of them. It’s a mammalian chemical, a small peptide, made mostly
in the hypothalamus, and it’s earned the nickname of the ‘cuddle
hormone’ - due to the fact that it’s produced ( and presumably
detected ) at what might be termed ‘ quality bonding moments ‘ .
. .
Now it’s hit the news again through a Swiss study published in this
week’s Nature magazine entitled “ Oxytocin
increases trust in humans “ The researchers gave a nasal spray
of the hormone ( or a placebo ) to a group of 194 male* students. The subjects
were then engaged in a ‘trust’ game – involving real money.
It was found that the students who received the spray ‘trusted’ significantly
more. About 20% more in fact ( if our maths is correct ).
“ We find that intranasal administration of oxytocin
causes a substantial increase in trusting behaviour.” was
the conclusion.
But our back-of-an-envelope analysis of the Swiss study shows that although
the chemically-induced increase in trust was very high – the actual
amounts, in real-world cash terms, were very low. The subjects were willing
to chance just an extra £0.25 or so – less than the price of
a postage stamp.
Would the results have been the same if the losses / gains were at a substantial
level - in other words at a level which made any significant difference whatsoever
to the lives of those involved ?
We’d also like to point out that there are several other chemicals,
already in everyday use, which really do substantially alter the way money
flows though the economy. Go to any bar around Liverpool St. station
( one of the main commuter routes out of the City of London’s uber-powerful
financial district ) on a Friday evening - and you’ll see plenty of
evidence of what fuels-up the City Boys.
Commentators have already suggested though ( in the same issue of Nature
) that “ political operators [ could ] generously
spray the crowd with Oxytocin at the rallies of their candidates “.
. .
Errrr . . . No, not really*.
We suggest that a generous supply of free beers may work substantially better.

Parrot deadline expires.
We’d like to remind any Brazilian readers that the deadline for handing-in
any parrots has just passed. A law passed in 1999 decreed that any parrots
( or other creatures ) which were taken from the wild ( rather than bred
in captivity ) must be handed over to specially created zoological departments
which will try to re-integrate the animals back into the wild.
The law ( not surprisingly ) has proved very difficult to implement, so
there have been several amnesties – the last of which has just expired.
It’s led to many anomalous situations. We learned yesterday of an
unhappy pet-owner who has just turned-in their pet/confidant - a parrot which
has lived with them for over thirty years. Clearly the bird is going
to have a great deal of difficulty re-integrating.
The penalty for pet owners non-compliance is a fine of up to £1000 – and
a possible jail sentence.

Military heads not Snafu or Fubar.
A team of doctors and psychiatrists from King's
College London and Defence Medical Services ( motto: “ A
Force for good in the world “ ) has just published the results
of a study ( this month’s British
Journal of Psychiatry ) into the psychological effects of military
service.
They gave a ‘self administered‘ psychological test – called
a GHQ-28, to 254 members of the UK's Air Assault Brigade before
deployment to Iraq last year.
The GHQ-28 is
a ‘tick the box’ test, with penetrating and revealing questions
such as :
“ have you recently been able to enjoy your
normal day-to-day activities ? “
“ have you recently found everything getting on top
of you ? “
“ have you recently been getting any pains in your
head ? “
etc etc etc.
When the personnel returned from their tour of duty, they were given the
test again - and the results “ indicated a highly
significant relative improvement in mental health “
The authors don’t go as far as advocate war as a benefit to the soldier’s
state of mind though – preferring instead the guarded conclusion “ War
is not necessarily bad for psychological health “.
Perhaps we can suggest an even simpler test ?
Why not ask the fighters “ are you happy to be going ? “ before
they leave – and then “ are you happy to be back home safely
? “ – when they return. We wonder which would score higher ?
As far as we can make out, the study didn’t examine the mental health
of the civilian population in Iraq, or any other war–torn area. Bearing
in mind that in all recent wars ( since WW1 ) the civilian population always
suffers far greater casualties that the military forces involved, maybe that
would be another idea for future King's College studies ?

Small [(often) =] blurred
Sometimes we make mistakes. Things slip under our radar. So we’d like
to apologise to readers for not spotting research published back in the February
issue of Psychonomic Bulletin & Review.
A joint effort from the University of Washington and the University
of California, it was entitled “ Why is
it easier to identify someone close than far away? “ and outlines
the “ distance-as-filtering hypothesis ”,
coupled with “ Face Identification Energy “.
Which, as we understand it, implies that, as a face moves farther away from
us, the ability to recognise it decreases in a manner inversely proportional
to distance.
The
study focused particularly on the ability of subjects ( 24 students ) to
recognise digitally filtered ‘ celebrity faces ‘ , and the following
formula was revealed :

( Where P = the number of celebrities recognised )
