at the beginning of time science lay dormant but to the yeoman
swing humankind have made the use of the reserves of a disposable much has been
lost due to an energy in green but the games are colossal
due to our vision and insight
London Fashion Week looks of fashionably unhealthy role models and the damage
they're doing to young girls in medical incidences of goiter in children reduced
by adding a double fortification of iron and iodine to salt in future a World
Health Organization report shows all nations that public health is affordable
at a reasonable cost an engineering breakthrough as Britain's motorway
stopovers provide all mod cons for the travelling businessman
in nature the surprising tropical splendor of England I love white Botanic
Gardens salmonella poisoning it kills hundreds of people each year but could a
device designed to test nuclear weapons hold the key to detecting the deadly
bacteria in our food today we take a look at scientists attempting to change
the way we view quality control motorway service areas usually offer an
opportunity for motorists to rest and grab a snack but what if you've got work
to do a report to write an important business
customer to meet this service area on a motorway heading out of London offers
more than the usual cafeteria and convenience stores
the answer they came up with was this a separate business area where you can
make calls plug in a laptop computer and hook up to the internet for emails or if
you want to hold a business meeting you can hire special rooms complete with
video conferencing equipment you can even conduct a job interview in private
instead of in a noisy restaurant the idea is called workspace and it's being
extended to other service areas on other motorways for Britain's four million
business travelers among motorists using this prototype workspace on the motorway
west of London the idea has proved time-saving convenient and popular so
standing around in noisy car parks trying to carry on a conversation with
important clients could be a thing of the past for travelling business people
it's unlikely to replace the office completely with its human interaction
but workspace is a useful idea likely to be picked up outside prison
China's economic expansion over the past two decades has been impressive but
according to the World Health Organization while per capita incomes in
China have risen they've not been matched by better health services for
the people the fact that welfare does not necessarily mean healthier is one of
the main findings of the wh o--'s first-ever report comparing the health
performances of different countries the message of the report is that everyone
with the available resources can do better the interest the World Health
Organization has in studying the performance of health systems is to help
countries learn from each other and to empower decision makers to improve the
performance of their health systems the World Health Organization believes that
by making critical comparisons between countries there are lessons to be
learned there are certain policies where the available monies whether they're
limited or more extensive can be used more effectively to get better health
for the population
not surprisingly health services in African countries burdened with chronic
disease internal conflict and now spiraling HIV cases are under stress but
there are also some examples in the report of poorer countries managing to
provide better healthcare than wealthier ones a man for example is number eight
in the world a man spends about 330 dollars per person on their health
system in a short time they've gone from a country that wasn't doing very well
with an infant death rate of one in four to a position where they're doing very
well indeed a good example that you can have a high performance health system at
relatively low cost but it also shows that a country can do something about
their health systems in a short period of time
this is the first attempt by the w-h-o to try to assess the success of health
services the criteria might be refined in future but already the organization
is confident of drawing some useful conclusions for example the report shows
that if patients prepay through taxation or insurance payments those systems do
better the World Health Organization's health league table will doubtless be
criticized by country's ranking lower than they feel they deserve but the
report is the first attempt to provide some objective measure of what health
output countries get for the money they put in
Sault a lack of it can lead to problems but it can also be the key to better
health a major breakthrough has allowed the addition of iodine and iron to salt
it could improve the health of more than half of the world's population here in
China a government-backed campaign to supply the double fortified salt has
improved the health of the nation and protected millions of children
incidences of goiter in children have been reduced but in some areas there's
still much work to be done almost all the children in this class have goiter
to some degree it means that the incidence of idd iodine deficiency
disorder is high even though the salt tested in the area looks good it is
deficient Community Health would respond markedly to the double fortification
initiative in the developing world if this problem is addressed through the
double fortification of salt you improve the iron stores of the population once
their iron stores improve people move from a severely anemic status to mild or
moderate anemic status which greatly improves their sense of well-being and
their productivity if they're involved in physical labor in young children it
could lead to improvement in cognitive development performance in schools and
all of these have huge economic implications as well
the process means that iron and iodine can be added to ordinary table salt at a
relatively low cost the salt is now protecting 85 million newborn children
worldwide the ideal would be for governments and private industries to
come together to address major nutritional problems like iron
deficiency amnesia and iron deficiency through a medium like salt it's an
extremely cost effective solution that just needs the will of governments and
industry to make it happen
in countries like Tanzania the double fortified salt can have a dramatic
effect on child health it's a major health breakthrough for many of the
world's poorest countries for the past two decades salmonella poisoning from
contaminated eggs has been recognized as a major public health concern in the
United States alone there are an estimated 1.4 million cases of this type
of food poisoning each year 500 of them fatal the problem for unsuspecting
consumers is that until now there's been no way of externally detecting the
Salmonella bacteria in eggs unlike earlier strains of the bacteria that
entered in perfect eggs through broken shells the current epidemic comes from
the ovaries of hens and appears in eggs that look and taste normal but
scientists at Los Alamos National Laboratories believe they may have found
the answer to detecting the disease in seemingly healthy eggs these members of
the engineering science and applications division are using nuclear weapons
research to develop a Salmonella testing device the simple technique involves
using acoustic sound analysis to determine the contents of the egg
including any unusual bacteria using an instrument called a swept frequency
acoustic interferometer the scientists have been able to identify Salmonella in
egg yolks within 20 seconds the acoustic device was developed at Los Alamos
several years ago in to identify the contents of munitions in
order to dispose of them safely instead of drilling a hole into an artillery
shell and extracting a sample for laboratory testing the interferometer or
an acoustic resonance spectroscopy ARS chemical filled detector allows weapon
inspectors to identify the contents of sealed metallic containers without
exposing themselves to the toxic chemicals within funded by the defense
nuclear agency an early version of the technique was successfully used in the
aftermath of the Gulf War when a United Nations team examined Iraq's chemical
weapons capabilities inspectors used the device to induce minut acoustic
vibrations or sound waves into the container and measure the response the
container resonated at certain frequencies determined by its material
properties a computer then matched these frequencies with results in a library of
acoustic signatures and identified the content safely given the fragile nature
of eggs researchers saw a potential for this technology to be used in
non-invasive salmonella testing with a few variations they developed an
acoustic device that could be used on eggs it involves placing two transducers
on the shell one acts as a transmitter emitting electric signals that excite
the egg and generate mechanical vibration the other picks up the
resonance as the egg vibrates a computer then tracks the pattern of vibration
generating an acoustic spectrum or signature for the egg in the same way as
it does for nuclear weapons to test the salmonella los angeles scientists
applied this technique to both fresh eggs and eggs which had been
artificially infected with the bacteria they found the two types had distinct
acoustic spectrums the fresh eggs had a clean single
resonance peak the Salmonella eggs had a second peak that was never found in the
healthy variety the question still remains whether the detection technique
will work on naturally contaminated eggs the researchers involved are hoping to
look at eggs from chicken houses known to have a high rate of Salmonella if
successful they believe the acoustic device could have wide applications in
egg quality control it could be used to detect cracks and double yolks and to
determine the thickness of the shell an important factor for shippers and
Packers the advantage of the technique is that
it is non-invasive making it attractive to consumers from the manufacturers
point of view it is more efficient than picking up each egg for an individual
inspection the only downfall is that scientists don't yet know if the device
will be able to detect the bacteria outside the yolk of the egg there have
been many documented cases of salmonella only on the shell
even so acoustic sound analysis is a useful tool in the war against Tel
Manila food poisoning with thousands of infections each year this test designed
to identify nuclear weapons could be the key to saving lives the Isle of Wight
just off Britain's south coast is a favorite holiday spot nearly three
million people visit the island every year some are drawn by the action-packed
week of world-class yacht racing at cows
for others it's the traditional attractions of the British seaside
holiday the island only 12 miles north to south and 23 across is renowned for
its sunny climate
at Ventnor a small town nestling at the southern end of the island
an unusual botanical garden is proving popular with visitors a quirk of the
local climate allow semi-tropical plants to thrive here
the gardens laid out on the side of a disused hospital are an important part
of the local economy
visitors are now able to do more than just look around the gardens a new 3
million dollar Visitor Center includes a library study center and both permanent
and temporary exhibitions and a pleasant place to sit out of the occasional rain
visitors can research the unique subtropical botanical collections in the
gardens study the natural environment of the Isle of Wight National Park or if
they like just read a book about their own garden the permanent exhibition
describes the history of plant life and its impact on our lives with its mix of
public education study facilities and its range of plants from distinctly
unbrushed climbs the Botanic Gardens is like a mini version of Q the
world-famous pretend gardens in West London the gardens include areas of
plants from New Zealand the Americas and the Mediterranean and themed areas like
medicinal and culinary borders and with its own microclimate the gardens can
stay open to visitors throughout the year
traffic jams may soon be a thing of the past thanks to a new computer transport
simulation system being developed in the United States scientists at the Los
Alamos National Laboratory are working to develop a program aimed at
forecasting and improving transportation in our cities using one of the most
powerful computers in the world for Silicon Graphics
origin mm they're creating realistic simulations of our streets in the hope
of identifying transport problems President Clinton was one of the first
to see the capabilities of this new technology when he visited the
laboratory recently he was shown how the transportation analysis and simulation
system or transients uses an integrated system of travel forecasting methods to
give planners an accurate picture of traffic impacts congestion and pollution
using previous transportation surveys transients models create a virtual
metropolitan region representing all its residents their activities and modes of
transport they then simulate the residents use of cars and buses on the
transport network mimicking real driving behavior and traffic dynamics this
simulation tries to capture how factors such as congestion could influence an
individual's activity plan they might change their route or go somewhere else
for instance the beauty of transience is that it contract individual travelers
this means analysts can evaluate how well one person's travel plans proceed
and can identify who might benefit from alternatives looking at the bigger
picture they can estimate vehicle emissions and judge the overall
performance of the transport system these results are intended to help
planners and engineers with future infrastructure design the whole program
aims to bring transportation and air quality forecasting up to the standard
required by new regulations including the Clean Air Act and the intermodal
efficiency Act the venture is part of a joint initiative known as the travel
model Improvement Program or TM IP it was initiated by several agencies
including the US Department of Transportation the Fed
highway administration and the US Environmental Protection Agency so far
the Los Alamos team has done major studies of Albuquerque and Dallas in
Dallas they created a simulation of traffic patterns over an area of 25
square miles key characteristics of this study included monitoring shared rides
high occupancy vehicles and Lane usage the program also used generic detector
technology to control simulated traffic signals and represent people who were
just passing through at the moment researchers are working towards creating
a simulation of a typical day in Portland Oregon from there the aim is to
develop commercially viable software which could be used by planners
everywhere but simulation technology is not just limited to transportation at
Los Alamos an entire team is dedicated to the Delphi project which uses
advanced simulation on the origin mm computer to tackle a range of important
national and global issues like transportation these problems are so
complex they cannot be solved using traditional scientific analysis Delphi
sophisticated predictive modeling conducts virtual experiments that
demonstrate the long term outcomes of variables such as human action and the
physical environment this method has already been used to predict the
behavior of natural disasters and global climate and to map the human brain the
possibilities are endless but there is no doubt these computer simulations will
change the way we view planning in the future they may do away with congestion
and pollution and ultimately help us learn more about the environment in
which we live
London Fashion Week and once again designers have chosen film seemingly
undernourished models to show off their clothes but it's this way flag image
that's worrying women and health experts across Britain today the government
along with doctors and fashion magazine editors convened a special summit to
address these concerns and initiate discussion on how to change a worrying
obsession with a skinny body image the meeting brought together the
representatives of the wide range of industry fashion television and media
people who can actually be instrumental in delivering change to the culture that
so many girls grow up in and which they find so oppressive the culture to be
thin which makes them feel most of them less than perfect recent research shows
that one of the biggest worries for British schoolgirls is their weight and
appearance and at a time when women are becoming heavier and models thinner the
pressure is mounting these teenagers who spoke at the summit said their views
represented the thousands of teenagers who are unhappy and confused over body
image and most of it is down to the fashion magazines men's magazines favour
women with a full figure in women's magazines it's always slim young girls
are not sure what are the perfect figures generally they thought the
emphasis should be on health rather than figure shape
currently it's estimated 100 girls suffers from the eating disorders
anorexia and bulimia there is no question a large percentage
of teenagers are influenced by fashion designers medical experts say it's now a
matter of re-education fashion designers of past ages would have said voluptuous
women like Sophia Loren or Marilyn Monroe with the perfect body shapes it
just shows you how capricious and arbitrary fashion design is once a fed
for a fashion type gains popularity it is difficult to change the conference
pressed for a diversity of imagery so that our eyes can be retrained to
evaluate the beauty that really exists
the summit the first of its kind to be held by the British government now hopes
to see the introduction of a self-regulating body for magazines in
other words a new code of conduct that works to ensure that unhealthy body
images do not reach the front pages of magazines at the same time the
broadcasting Standards Commission has offered to monitor the images which
appear on British television
