2014 is also the International Year of Crystallography - a new campaign to raise awareness of the wonderful technique that has revealed the secrets of DNA and drug discovery. It will also promote collaboration among scientists in Africa and Asia. And finally, this wouldn't be a "preview of the next big thing" without graphene. The "wonder-material" (a one-atom-thick sheet of carbon) has been championed for use in condoms and microscopes. And for its next trick... graphene will allow bendable touchscreens on smartphones, according to Physics World.
In 1914, Max von Laue won the Nobel Prize in Physics for
discovering that crystals could diffract X-rays, a finding that helped
revolutionize our ability to visualize matter at the atomic scale.
In honor of this centennial, the United Nations Educational,
Scientific & Cultural Organization (UNESCO) has declared 2014 the
International Year of Crystallography (IYCr).
We are celebrating “100 years of groundbreaking discoveries” in
crystallography, said Ban Ki-Moon, secretary-general of the UN, in a
video webcast of IYCr’s opening ceremonies in Paris on Jan. 20–21.
“Humans have always been fascinated by crystals,” said Irina Bokova,
director-general of UNESCO. For example, ancient Indian literature on
mineralogy has been dated to 1100 B.C. “Not only do [crystals] add
beauty to this world, they shape it and help us understand it,” Bokova
said.
From the giant gemstones found in caves to the crystals that are
found in artist pigments, in martian rock formations, and on the lab
benches of pharmaceutical scientists, “there is no branch of structural
science that is untouched by crystallography,” said Gautam R. Desiraju,
president of the International Union of Crystallography. According to
IUCr, a total of 29 Nobel Prizes
have been awarded for work related to crystallography. These range from
the discovery of X-rays by Wilhelm Röntgen at the turn of the last
century to more recent awards for quasicrystals and structures of the
ribosome and G protein-coupled receptors.
Bokova quoted Dorothy Crowfoot Hodgkin,
who won the 1964 Nobel Prize in Chemistry for her use of X-ray
crystallography to determine the structure of biological molecules such
as vitamin B-12, as having said, “I was captured for life by chemistry
and crystals.”
“The International Year of Crystallography is an opportunity to share
this passion and to share it around the world,” Bokova added.
To celebrate crystallography, plans are afoot to set up
crystal-growing programs for kids, crystallography laboratories in 20
countries worldwide that will be open to the public, and summit meetings
for policymakers, Desiraju said. A new open-access publication, IUCrJ, was also launched in January as part of the festivities.
