Scientists from the RIKEN, in collaboration with international partners, have succeeded in creating an ultrathin organic solar cell that is both highly efficient and durable. Using a simple post-annealing process, they created a flexible organic cell that degrades by less than 5 percent over 3,000 hours in atmospheric conditions and that simultaneously has an energy conversion ratio—a key indicator of solar cell performance—of 13 percent.

The 3rd Global Ministerial Conference on Road Safety convened 1700 delegates from around 140 countries, including more than 70 ministers and vice-ministers and heads of international agencies, civil society organizations, foundations and private companies. Hosted at the request of the UN General Assembly by the Government of Sweden in collaboration with WHO, the theme was “Achieving Global Goals 2030”, highlighting the connections between road safety and achievement of other Sustainable Development Goal targets.
Through its 6 high-level panels and 18 parallel sessions, the Ministerial Conference addressed a range of topics, from building effective leadership for road safety to promoting sustainable cities and communities, mitigating climate change through road safety, and ensuring the safety of pedestrians and cyclists. The gathering was instrumental in reviewing progress in the Decade of Action for Road Safety 2011-2020 and defining ways to accelerate action on proven strategies to save lives. Among many pre-events, the 2nd World Youth Assembly for Road Safety hosted by YOURS: Youth for Road Safety and co-hosted by WHO, brought 200 young leaders together proclaiming “Enough is enough!” and claiming their space at the decision-making table for sustainable mobility.
The Ministerial Conference culminated in the forward-looking “Stockholm Declaration”, which calls for a new global target to reduce road traffic deaths and injuries by 50% by 2030. In addition, it invites strengthened efforts on activities in all five pillars of the Global Plan for the Decade of Action: better road safety management; safer roads, vehicles and people; and enhanced post-crash care. It also calls for speeding up the shift to safe, affordable, accessible and sustainable modes of transport like walking, cycling and public transport. WHO is asked to continue to produce the series of global status reports, as a means of monitoring progress towards achievement of the 12 Global Road Safety Performance Targets.
Today, around 1.35 million people lose their lives on the world’s roads every year, and as many as 50 million are injured. More than one quarter of those killed and injured are pedestrians and cyclists. Road traffic injuries are now the leading cause of death for children and young adults aged 5-29 years. Given the enormous human suffering and major economic losses for families and societies, road traffic deaths remain an unacceptable price to pay for mobility.

Introductory statistics courses teach us that, when fitting a model to some data, we should have more data than free parameters to avoid the danger of overfitting—fitting noisy data too closely, and thereby failing to fit new data. It is surprising, then, that in modern deep learning the practice is to have orders of magnitude more parameters than data. Despite this, deep networks show good predictive performance, and in fact do better the more parameters they have. Why would that be?

No single country is adequately protecting children’s health, their environment and their futures, finds a landmark report released today by a Commission of over 40 child and adolescent health experts from around the world. The Commission was convened by the World Health Organization (WHO), UNICEF and The Lancet.
The report, A Future for the World’s Children?, finds that the health and future of every child and adolescent worldwide is under immediate threat from ecological degradation, climate change and exploitative marketing practices that push heavily processed fast food, sugary drinks, alcohol and tobacco at children.
“Despite improvements in child and adolescent health over the past 20 years, progress has stalled, and is set to reverse,” said former Prime Minister of New Zealand and Co-Chair of the Commission, Helen Clark. “It has been estimated that around 250 million children under five years old in low- and middle-income countries are at risk of not reaching their developmental potential, based on proxy measures of stunting and poverty. But of even greater concern, every child worldwide now faces existential threats from climate change and commercial pressures.
“Countries need to overhaul their approach to child and adolescent health, to ensure that we not only look after our children today but protect the world they will inherit in the future,” she added.
The report includes a new global index of 180 countries, comparing performance on child flourishing, including measures of child survival and well-being, such as health, education, and nutrition; sustainability, with a proxy for greenhouse gas emissions, and equity, or income gaps. [Top & Bottom 10 countries; Full Global Index on pp. 35-38] [1]
According to the report, while the poorest countries need to do more to support their children’s ability to live healthy lives, excessive carbon emissions – disproportionately from wealthier countries – threaten the future of all children. If global warming exceeds 4°C by the year 2100 in line with current projections, this would lead to devastating health consequences for children, due to rising ocean levels, heatwaves, proliferation of diseases like malaria and dengue, and malnutrition.
The index shows that children in Norway, the Republic of Korea, and the Netherlands have the best chance at survival and well-being, while children in Central African Republic, Chad, Somalia, Niger and Mali face the worst odds. However, when authors took per capita CO2 emissions into account, the top countries trail behind: Norway ranked 156, the Republic of Korea 166, and the Netherlands 160. Each of the three emits 210% more CO2 per capita than their 2030 target. The United States of America (USA), Australia, and Saudi Arabia are among the ten worst emitters.
“More than 2 billion people live in countries where development is hampered by humanitarian crises, conflicts, and natural disasters, problems increasingly linked with climate change,” said Minister Awa Coll-Seck from Senegal, Co-Chair of the Commission. “While some of the poorest countries have among the lowest CO2 emissions, many are exposed to the harshest impacts of a rapidly changing climate. Promoting better conditions today for children to survive and thrive nationally does not have to come at the cost of eroding children’s futures globally.”
The only countries on track to beat CO2 emission per capita targets by 2030, while also performing fairly (within the top 70) on child flourishing measures are: Albania, Armenia, Grenada, Jordan, Moldova, Sri Lanka, Tunisia, Uruguay and Viet Nam.
The report also highlights the distinct threat posed to children from harmful marketing. Evidence suggests that children in some countries see as many as 30,000 advertisements on television alone in a single year, while youth exposure to vaping (e-cigarettes) advertisements increased by more than 250% in the USA over two years, reaching more than 24 million young people.
Professor Anthony Costello, one of the Commission’s authors, said: “Industry self-regulation has failed. Studies in Australia, Canada, Mexico, New Zealand and the USA – among many others – have shown that self-regulation has not hampered commercial ability to advertise to children. For example, despite industry signing up to self-regulation in Australia, children and adolescent viewers were still exposed to 51 million alcohol ads during just one year of televised football, cricket and rugby. And the reality could be much worse still: we have few facts and figures about the huge expansion of social media advertising and algorithms aimed at our children.”
Children’s exposure to commercial marketing of junk food and sugary beverages is associated with purchase of unhealthy foods and overweight and obesity, linking predatory marketing to the alarming rise in childhood obesity. The number of obese children and adolescents increased from 11 million in 1975 to 124 million in 2016 – an 11-fold increase, with dire individual and societal costs.
To protect children, the independent Commission authors call for a new global movement driven by and for children. Specific recommendations include:
Dr. Richard Horton, Editor-in-Chief of The Lancet family of journals, said: “The opportunity is great. The evidence is available. The tools are at hand. From heads-of-state to local government, from UN leaders to children themselves, this Commission
calls for the birth of a new era for child and adolescent health. It will take courage and commitment to deliver. It is the supreme test of our generation.”
“From the climate crisis to obesity and harmful commercial marketing, children around the world are having to contend with threats that were unimaginable just a few generations ago,” said Henrietta Fore, UNICEF Executive Director. “It
is time for a rethink on child health, one which places children at the top of every government’s development agenda and puts their well-being above all considerations.”
“This report shows that the world’s decision makers are, too often, failing today’s children and youth: failing to protect their health, failing to protect their rights, and failing to protect their planet,” Dr Tedros Adhanom Ghebreyesus,
Director-General of the World Health Organization said. “This must be a wakeup call for countries to invest in child health and development, ensure their voices are heard, protect their rights, and build a future that is fit for children.”

The theme of the 5th International Day of Women and Girls in Science, was on driving Investment in Equality in Science, Technology and Innovation in the Digitalization Era for Inclusive Green Growth with special focus on Agriculture, Technology and Digital Economy. The commemoration brought together stakeholders from high-level government officials, representatives of international organizations, foundations, private sector, civil society as well as women in science experts from around the world to explore how women in all fields of sciences can accelerate socio-economic sustainable development.
Discussion focused on the interlinkages between gender inequality -specifically in science- digital and technological revolution, and agricultural sector for Sustainable Development. WUN Executive Director Dr Nata Menabde participated in the assembly and highlighted the key role of women and girls in science for health and emphasized on the obstacles women and girls encounter in various levels of health sector – from access to health services, to engagement in health workforce and research. She explained the systematic challenges where women are facing higher health costs than men due to their greater use of health care, as well as the need to extend coverage of health care that deals with the content of benefit packages, to ensure they include a greater range of services for girls and women of all ages. Dr Menabde also shared some conclusions from WHO’s work on nutrition, stressing that gender inequality means girls get less food, are more likely to get sick, and are less likely to be able to attend school, receive an education (including on science) and get a job. However, they are more likely to marry and get pregnant too young, be poorly nourished and have under-nourished babies. In conclusion, she mentioned that healthy women and girls are the cornerstone of healthy societies and proper nutrition is essential to empowering women and girls. Nutrition, through its effect on health and cognitive development, is also vital for academic performance and productivity to ensure healthy economies and socioeconomic development.
