WASHINGTON — Getting blood or other perishable supplies to an area that’s been struck by an earthquake or hurricane isn’t as simple as asking what brown can do for you. But a new model quickly determines the best routes and means for delivering humanitarian aid, even in situations where bridges are out or airport tarmacs are clogged with planes.
The research, presented February 18 at the annual meeting of the American Association for the Advancement of Science, could help get supplies to areas which have experienced natural disasters or help prepare for efficient distribution of vaccines when the flu hits.
Efficient supply chains have long been a goal of manufacturers, but transport in fragile networks — where supply, demand and delivery routes may be in extremely rapid flux — requires a different approach, said Anna Nagurney of the University of Massachusetts Amherst, who presented the new work. Rather than considering the shortest path from one place to another to maximize profit, her system aims for the cleanest path at minimum cost, while capturing factors such as the perishability of the product and the uncertainty of supply routes. ‘You don’t know where demand is, so it’s tricky,’ said Nagurney. ‘It’s a multicriteria decision-making problem.’
By calculating the total cost associated with each link in a network, accounting for congestion and incorporating penalties for time and products that are lost, the computer model calculates the best supply chain in situations where standard routes may be disrupted.
‘Mathematical tools are essential to develop formal means to predict, and to respond to, such critical perturbations,’ said Iain Couzin of Princeton University, who uses similar computational tools to study collective animal behavior. ‘This is particularly important where response must be rapid and effective, such as during disaster scenarios … or during epidemics or breaches of national security.
’ The work can be applied to immediate, pressing situations, such as getting blood, food or medication to a disaster site, or to longer-term problems such as determining the best locations for manufacturing flu vaccines. . Retrieved April 7th, 2011.

YOUTH PROLONGED: OLD AGE POSTPONED
by Robert Weale (King's College London, UK)
What exactly is human ageing? Can it be slowed down?
These questions have puzzled scientists and laymen alike
for generations, and continue to do so today. The author
addresses these thought-provoking issues by challenging
pre-conceived notions of age-perception, age-acceptance
and inter-age relations. Pertinent matters of age-related
communication are dealt with, and the reader is treated to
a grand tour of the latest theories of ageing, age-related
biological changes and age-related diseases, such as
Alzheimer's Disease. Here, the author's expertise in agerelated
eye diseases truly comes into its own.
Weale's unique work not only underlines important
genetic and avoidable risk factors but gives ample
consideration to possible consequences stemming from
different early lifestyles. Readers will re-consider their
ideas of what it means to age, and gain a better
understanding of what can and cannot slow down the
process of ageing.
