UN TO RAISE AWARENESS OF LITTLE-KNOWN SCIENCE BEHIND DNA, COMPUTER
MEMORIES, NEW DRUGSNew York, Jan 20 2014 12:00PMIt is at the very core
of revealing the structure of DNA, fabricating computer memories and
designing potent new drugs, but only a tiny fraction of the world's
people are aware of the science of crystallography, a knowledge gap
the United Nations hopes to help erase this year.

At the Paris headquarters of the UN Educational, Scientific and
Cultural Organization (UNESCO) next Monday, the International Year of
Crystallography will be formally launched, followed by three regional
summit meetings – in Karachi, Pakistan, from 28 to 30 April; Campinas,
Brazil, from 21 to 24 September; and Bloemfontein, South Africa, from
15 to 17 October.

These meetings are to serve as platforms for exchange between
decision-makers and scientists and are intended to favour the
development of crystallography research.

"This year marks the centenary of the birth of modern
crystallography," Secretary-General Ban Ki-moon said in a
<"http://www.un.org/sg/statements/index.asp?nid=7410">message for
today's launch. "We celebrate 100 years of ground-breaking advances."

The year 2014 marks the centennial of the birth of X-ray
crystallography, thanks to the work of William Henry and William
Lawrence Bragg (father and son), and Max von Laue who was awarded the
1914 Nobel Prize in Physics for his discovery of the diffraction of
X-rays by crystals. In 2012 the UN General Assembly proclaimed it the
International Year of Crystallography.

UNESCO, the only UN organization with a mandate covering basic
sciences, was charged with coordinating related events in cooperation
with International Union of Crystallography (IUCr), to highlight the
continuing importance of the science and its role in addressing
post-2015 development issues such as food security, safe drinking
water, health care, sustainable energy and environmental remediation.

"Crystallography also has an important place as we work for inclusive
sustainable development – policies that are good for people and the
planet," Mr. Ban said. The UN is now accelerating efforts towards the
eight anti-poverty targets known as the Millennium Development Goals
(MDGs) and the sustainable development goals that will take over after
the 2015 deadline.

UNESCO Director-General Irina Bokova and IUCr President Gautam R.
Desiraju will preside over the opening session of next week's two-day
event at which scientific advances linked to crystallography and its
potential for development, notably in emerging nations, will be
discussed.

The science studies the composition and structure of crystals. In the
early 20th century, it was discovered that X-rays could be used to
'see' the structure of matter in a non-intrusive manner, allowing
study of the arrangement of atoms in solids and the chemical bonds
that draw one atom to another. Crystallographers now apply this
knowledge to modify a structure and thus change its properties and
behaviour.

"Since this discovery, crystallography has become the very core of
structural science, revealing the structure of DNA, allowing us to
understand and fabricate computer memories, showing us how proteins
are created in cells and helping scientists to design powerful new
materials and drugs," UNESCO
<"http://www.unesco.org/new/en/natural-sciences/science-technology/basic-sciences/infocus-bes/international-year-of-crystallography-2014/">says.

"Thus crystallography has many applications. It permeates our daily
lives and forms the backbone of industries which are increasingly
reliant on knowledge generation to develop new products, in widely
diverse fields that include agro-food, aeronautics, automobiles,
cosmetics and computers as well as the electro-mechanical,
pharmaceutical and mining industries.

"On the crossroads of physics, chemistry and biology, as well as
mathematics, crystallography has had numerous applications in the
agro-food industry and pharmaceutics as well as technology, allowing,
for example, for the development of liquid crystal screens."

As an example of its multiple applications one of the subjects to be
discussed next week is crystallography's relations to Islamic art and
architecture.

As part of the awareness-raising activities, crystallography
demonstration laboratories will be set up throughout the year in
universities around the world, be equipped with diffractometers,
measuring instrument used to analyse the structure of a material, made
available by their manufacturers free of charge.

These labs will be used to stimulate international scientific
cooperation and train scientists in the use the instruments, as well
as carrying out experiments in the presence of students.

A crystal growing competition will also be open to secondary school
students all over the world. UNESCO and IUCr will provide interested
classes with teaching kits. The competition involves using a saturated
saline solution to grow a single crystal with the purpose of obtaining
the largest, purest and most beautiful crystal possible. Jan 20 2014
