A day late but better than never: 2019 International Day of Women and Girls in Science

February 11, 2019 was the International Day of Women and Girls in Science but there’s at least one celebratory event that is extended to include February 12. So, I’ll take what I can get and jump on to that bandwagon too. Happy 2019 International Day of Women and Girls in Science—a day late!

To make up fr being late to the party, I have two news items to commemorate the event.

21st Edition of the L’Oréal-UNESCO International Awards for Women in Science

From a February 11, 2019 UNESCO (United Nations Educational, Scientific and Cultural Organization) press release received via email,

Paris, 11 February [2019]—On the occasion of the International Day of Women and Girls in Science celebrated on 11 February, the L’Oréal Foundation and UNESCO have announced the laureates of the 21st International Awards For Women in Science, which honours outstanding women scientists, from all over the world. These exceptional women are recognized for the excellence of their research in the fields of material science, mathematics and computer science.

Each laureate receive €100,000 and their achievements will be celebrated alongside those of 15 promising young women scientists from around the world at an awards ceremony on 14 March [2019] at UNESCO’s Headquarters in Paris.


Mathematics is a prestigious discipline and a source of innovation in many domains, however, it is also one of the scientific fields with the lowest representation of women at the highest level. Since the establishment of the three most prestigious international prizes for the discipline (Fields, Wolf and Abel), only one woman mathematician has been recognized, out of a total of 141 laureates.

The L’Oréal Foundation and UNESCO have therefore decided to reinforce their efforts to empower women in science by extending the International Awards dedicated to material science to two more research areas: mathematics and computer science.

Two mathematicians now figure among the five laureates receiving the 2019 For Women in Science Awards: Claire Voisin, one of five women to have received a gold medal from the the French National Centre for Scientific Research (CNRS), and the first women mathematician to enter the prestigious Collège de France, and Ingrid Daubechies of Duke University (USA), the first woman researcher to head the International Mathematical Union.


In the field of scientific research, the glass ceiling is still a reality: Women only account for 28% of researchers, occupy just 11% of senior academic positions,[4] and number a mere 3% of Nobel Science Prizes

Since 1998, the L’Oréal Foundation, in partnership with UNESCO, has worked to improve the representation of women in scientific careers, upholding the conviction that the world needs science, and science needs women.

In its first 20 years, the For Women in Science programme supported and raised the profiles of 102 laureates and more than 3,000 talented young scientists, both doctoral and post-doctoral candidates, providing them with research fellowships, allocated annually in 117 countries.

“Investment in Women in Science for Inclusive Green Growth” (conference) 11 – 12 February 2019

This conference is taking place at UN (United Nations) headquarters in New York City. There is an agenda which includes the talks for February 12, 2019 and they feature a bit of a surprise,

[February 12, 2019]
10.00 – 12.30:
High-Level Panel on:
Investment in Science Education for Shaping Society’s Future

Scientists contribute greatly to the economic health and wealth of a nation.
However, worldwide, the levels of participation in science and technology in
school and in post-school education have fallen short of the expectations of
policy-makers and the needs of business, industry, or government.

The continuing concern to find the reasons why young people decide not to
study science and technology is a critical one if we are to solve the underlying
problem.  Furthermore, while science and technology play key roles in today’s
global economy and leveling the playing field among various demographics,
young people particularly girls are turning away from science subjects. Clearly,
raising interest in science among young people is necessary for increasing the
number of future science professionals, as well as, providing opportunities for
all citizens of all countries to understand and use science in their daily lives.

To achieve sustainable development throughout the world, education policy
makers need to allocate high priority and considerable resources to the
teaching of science and technology in a manner that allows students to learn
science in a way that is practiced and experienced in the real world by real
scientists and engineers. Furthermore, to accomplish this goal, sustained
support is needed to increase and improve teacher training and professional
learning for STEM educators. By meeting these two needs, we can better
accomplish the ultimate aim which is to educate the scientists, technologists,
technicians, and leaders on whom future economic development is perceived to
depend over a sustained period of time.

In line with the 2019 High-Level Political Forum, this session will discuss
SDG [Sustainable development goal] 4 with special focus on Science Education.

Reforming the science curriculum to promote learning science the way it is practiced and experienced in the real world by real scientists and engineers.

Providing quality and prepared teachers for every child to include increasing the number of women and other underrepresented demographic role models for students.

Considering how science education provides us with a scientifically adept society, one ready to understand, critique and mold the future of research, as well as, serving as an integral part of feeding into the pipeline for future scientists.

Identifying factors influencing participation in science, engineering and technology as underrepresented populations including young girls make the transition from school to higher education

Parallel Panel
10.00 – 13.00:
Girls in Science for Sustainable Development: Vision to Action

This Panel will be convened by young change-makers and passionate girls in
science advocates from around the world to present their vision on how they can
utilize science to achieve sustainable development goals.  Further, girls in
science will experience interacting and debating with UN Officials, Diplomates,
women in science and corporate executives.   

This Panel will strive to empower, educate and embolden the potential of every
girl.  The aim of this Panel is give girls the opportunity to gain core leadership
skills, training in community-building and advocacy.

In line with the 2019 United Nations High-Level Political Forum, Girls in
Science will focus around:
SDG 4 aims to promote lifelong learning opportunities for all. How can we improve science education around the world? What resources or opportunities would be effective in achieving this goal? And How can we use technology to improve science education and opportunities for students around the world?

Nearly ½ of the world population live in poverty. SDG 8 aims to promote sustained, inclusive, and sustainable economic growth, full and productive employment, and decent work for all. What is the importance of STEM for girls and women for economic growth and how do we encourage and implement this? What role does science and technology play in reducing poverty around the world?

SDG 10 aims to reduce inequalities around the world. What are some current inequalities that girls are facing and what can be done to ameliorate this?

Following the Paris Agreement a few years back, climate change has become an increasingly discussed topic; SDG 13 focuses on climate action. What is the significance of this Sustainable Development Goal today and what contribution does women and girls in science make on this issue?

What is being done in your communities to solve the SDGs in this respect? Has it been effective? Why or why not? Would it be effective in other countries? What are some issues you or people you know face in your country in relation to these concerns?

13.00 – 14.45: Lunch Break

15.00 – 16.30:

High-Level Session on: The Science of Fashion for Sustainable Development

Fashion embodies human pleasure, creativity, social codes and technologies
that have enabled societies to prosper, laid burdens on the environment and
caused competition for arable land.  No single actor, action nor technology is
sufficient to shift us away from the environmental and social challenges
embedded in the fashion industry – nor to meet the demands for sustainable
development of society at large. However, scientific and technological
developments are important for progress towards sustainable fashion.  This
Panel aims to shed light on the role of science, technology, engineering and
mathematics skills for fashion and sustainability.

16.45 – 18.00: Closing Session
Summary of Panels and Sessions by Chairs and Moderators

Introducing the International Framework and Action Plan for Member States to Approve and Adopt

Announcing the Global Fund for Women and Girls in Science

It’s good to see the UN look at fashion and sustainability. The ‘fashion’ session makes the endeavour seem a little less stuffy.

Gold-144 is a polymorph

Au-144 (also known as Gold-144) is an iconic gold nanocluster according to a June 14, 2016 news item announcing its polymorphic nature on ScienceDaily,

Chemically the same, graphite and diamonds are as physically distinct as two minerals can be, one opaque and soft, the other translucent and hard. What makes them unique is their differing arrangement of carbon atoms.

Polymorphs, or materials with the same composition but different structures, are common in bulk materials, and now a new study in Nature Communications confirms they exist in nanomaterials, too. Researchers describe two unique structures for the iconic gold nanocluster Au144(SR)60, better known as Gold-144, including a version never seen before. Their discovery gives engineers a new material to explore, along with the possibility of finding other polymorphic nanoparticles.

A June 14, 2016 Columbia University news release (also on EurekAlert), which originated the news item, provides more insight into the work,

“This took four years to unravel,” said Simon Billinge, a physics professor at Columbia Engineering and a member of the Data Science Institute. “We weren’t expecting the clusters to take on more than one atomic arrangement. But this discovery gives us more handles to turn when trying to design clusters with new and useful properties.”

Gold has been used in coins and jewelry for thousands of years for its durability, but shrink it to a size 10,000 times smaller than a human hair [at one time one billionth of a meter or a nanometer was said to be 1/50,000, 1/60,000 or 1/100,000 of the diameter of a human hair], and it becomes wildly unstable and unpredictable. At the nanoscale, gold likes to split apart other particles and molecules, making it a useful material for purifying water, imaging and killing tumors, and making solar panels more efficient, among other applications.

Though a variety of nanogold particles and molecules have been made in the lab, very few have had their secret atomic arrangement revealed. But recently, new technologies are bringing these miniscule structures into focus.

Under one approach, high-energy x-ray beams are fired at a sample of nanoparticles. Advanced data analytics are used to interpret the x-ray scattering data and infer the sample’s structure, which is key to understanding how strong, reactive or durable the particles might be.

Billinge and his lab have pioneered a method, the atomic Pair Distribution Function (PDF) analysis, for interpreting this scattering data. To test the PDF method, Billinge asked chemists at the Colorado State University to make tiny samples of Gold-144, a molecule-sized nanogold cluster first isolated in 1995. Its structure had been theoretically predicted in 2009, and though never confirmed, Gold-144 has found numerous applications, including in tissue-imaging.

Hoping the test would confirm Gold-144’s structure, they analyzed the clusters at the European Synchrotron Radiation Source in Grenoble, and used the PDF method to infer their structure. To their surprise, they found an angular core, and not the sphere-like icosahedral core predicted. When they made a new sample and tried the experiment again, this time using synchrotrons at Brookhaven and Argonne national laboratories, the structure came back spherical.

“We didn’t understand what was going on, but digging deeper, we realized we had a polymorph,” said study coauthor Kirsten Jensen, formerly a postdoctoral researcher at Columbia, now a chemistry professor at the University of Copenhagen.

Further experiments confirmed the cluster had two versions, sometimes found together, each with a unique structure indicating they behave differently. The researchers are still unsure if Gold-144 can switch from one version to the other or, what exactly, differentiates the two forms.

To make their discovery, the researchers solved what physicists call the nanostructure inverse problem. How can the structure of a tiny nanoparticle in a sample be inferred from an x-ray signal that has been averaged over millions of particles, each with different orientations?

“The signal is noisy and highly degraded,” said Billinge. “It’s the equivalent of trying to recognize if the bird in the tree is a robin or a cardinal, but the image in your binoculars is too blurry and distorted to tell.”

“Our results demonstrate the power of PDF analysis to reveal the structure of very tiny particles,” added study coauthor Christopher Ackerson, a chemistry professor at Colorado State. “I’ve been trying, off and on, for more than 10 years to get the single-crystal x-ray structure of Gold-144. The presence of polymorphs helps to explain why this molecule has been so resistant to traditional methods.”

The PDF approach is one of several rival methods being developed to bring nanoparticle structure into focus. Now that it has proven itself, it could help speed up the work of describing other nanostructures.

The eventual goal is to design nanoparticles by their desired properties, rather than through trial and error, by understanding how form and function relate. Databases of known and predicted structures could make it possible to design new materials with a few clicks of a mouse.

The study is a first step.

“We’ve had a structure model for this iconic gold molecule for years and then this study comes along and says the structure is basically right but it’s got a doppelgänger,” said Robert Whetten, a professor of chemical physics at the University of Texas, San Antonio, who led the team that first isolated Gold-144. “It seemed preposterous, to have two distinct structures that underlie its ubiquity, but this is a beautiful paper that will persuade a lot of people.”

Here’s an image illustrating the two shapes,
