Chemistry must respond to the crisis of transgression of planetary boundaries.

Recent assessments alarmingly indicate that many of the world's leading chemicals are transgressing one or more of the nine planetary boundaries, which define safe operating spaces within which humanity can continue to develop and thrive for generations to come. The unfolding crisis cannot be ignored and there is a once-in-a-century opportunity for chemistry - the science of transformation of matter - to make a critical difference to the future of people and planet. How can chemists contribute to meeting these challenges and restore stability and strengthen resilience to the planetary system that humanity needs for its survival? To respond to the wake-up call, three crucial steps are outlined: (1) urgently working to understand the nature of the looming threats, from a chemistry perspective; (2) harnessing the ingenuity and innovation that are central to the practice of chemistry to develop sustainable solutions; and (3) transforming chemistry itself, in education, research and industry, to re-position it as 'chemistry for sustainability' and lead the stewardship of the world's chemical resources.

The Challenge of Reaching Undocumented Migrants with COVID-19 Vaccination.

Access to vaccination against a health threat such as that presented by the COVID-19 pandemic is an imperative driven, in principle, by at least three compelling factors: (1) the right to health of all people, irrespective of their status; (2) humanitarian need of undocumented migrants, as well as of others including documented migrants, refugees and displaced people who are sometimes vulnerable and living in precarious situations; and (3) the need to ensure heath security globally and nationally, which in the case of a global pandemic requires operating on the basis that, for vaccination strategies to succeed in fighting a pandemic, the highest possible levels of vaccine uptake are required. Yet some population segments have had limited access to mainstream health systems, both prior to as well as during the COVID-19 pandemic. People with irregular resident status are among those who face extremely high barriers in accessing both preventative and curative health care.

A shared future: chemistry's engagement is essential for resilience of people and planet.

Strengthening resilience-elasticity or adaptive capacity-is essential in responding to the wide range of natural hazards and anthropogenic changes humanity faces. Chemistry's roles in resilience are explored for the first time, with its technical capacities set in the wider contexts of cross-disciplinary working and the intersecting worlds of science, society and policy. The roles are framed by chemistry's contributions to the sustainability of people and planet, examined via the human security framework's four material aspects of food, health, economic and environmental security.

COVID-19: Marking the Gaps in Migrant and Refugee Health in Some Massive Migration Areas.

The health of migrants and refugees, which has long been a cause for concern, has come under greatly increased pressure in the last decade. Against a background where the world has witnessed the largest numbers of migrants in history, the advent of the COVID-19 pandemic has stretched the capacities of countries and of aid, health and relief organizations, from global to local levels, to meet the human rights and pressing needs of migrants and refugees for access to health care and to public health measures needed to protect them from the pandemic. The overview in this article of the situation in examples of middle-income countries that have hosted mass migration in recent years has drawn on information from summaries presented in an M8 Alliance Expert Meeting, from peer-reviewed literature and from reports from international agencies concerned with the status and health of migrants and refugees.

Re-imagining Priorities for Chemistry: A Central Science for "Freedom from Fear and Want".

Human security, defined as "freedom from want and fear and freedom to live in dignity", provides an overarching concept to address threats to human security dimensions such as health, food, economics, the environment and sustainable development, while placing the individual at the centre of attention. Chemistry is central to addressing these challenges, but surprisingly its role and contributions to human security have hitherto not been explicitly set out. This article situates chemistry in the human security framework, highlighting areas where chemistry knowledge, methods and products are vital.

Realigning science, society and policy in uncertain times.

Against a backdrop of rapidly changing social, economic and geopolitical settings and ideologies, the world is facing a wide range of challenges, including in biodiversity, climate, energy, the environment, food, health and water. These can only be addressed by fully harnessing key capacities that science offers. However, there is a crisis of trust in science which affects some sections of society and some policy-makers, impairing the capacity of science to deliver its essential roles.

Blocking the Hype-Hypocrisy-Falsification-Fakery Pathway is Needed to Safeguard Science.

In chemistry and other sciences, hype has become commonplace, compounded by the hypocrisy of those who tolerate or encourage it while disapproving of the consequences. This reduces the credibility and trust upon which all science depends for support. Hype and hypocrisy are but first steps down a slippery slope towards falsification of results and dissemination of fake science.

Fake science and the knowledge crisis: ignorance can be fatal.

Computers, the Internet and social media enable every individual to be a publisher, communicating true or false information instantly and globally. In the 'post-truth' era, deception is commonplace at all levels of contemporary life. Fakery affects science and social information and the two have become highly interactive globally, undermining trust in science and the capacity of individuals and society to make evidence-informed choices, including on life-or-death issues.

Living Messages from Chemistry Icons: Legacies with Contemporary Relevance.

Beyond individual scientific virtuosity and creativity that leading figures in chemistry have displayed, they have sometimes conveyed wider messages of significance beyond their own professional specialization. They include insights into broader aspects of science, society or the ways of the world. On the other hand, the words, attitudes and actions of eminent chemists from former times have not always presented good models for others to follow, whether judged by their own contemporary or our present standards.

The Chemical Sciences and Equality, Diversity, and Inclusion.

There has been mounting concern over the absence of gender equality in the sciences in recent years. This has been accompanied by a broadening of the perspective, in order to address issues of equality, diversity and inclusion, relating to a wide range of circumstances in which individuals suffer discrimination. While some progress has been made in some countries, nationally or at the level of institutions, much more needs to be done.

The Chemical Sciences and Health: Strengthening Synergies at a Vital Interface.

The indispensable contributions to health made by the chemical sciences have become increasingly constrained by three systemic factors. These involve fragmentations: in the way that the chemicals sciences are structured, practiced, and inter-related to aspects of health; in the combination of public and private efforts delivering medicinal products; and in the regulatory systems which oversee health-related issues across health, food, and the environment. Interlinked systemic reforms are advocated, involving (1) recontextualization of the chemistry/health interface through creating a recognized field of "the chemical sciences and health"; (2) determined and comprehensive efforts, by countries wishing to retain or strengthen their pharmaceutical development capacities, to reinforce their education, research, and innovation eco-systems; and (3) adoption of an integrated approach to the regulation of pharmaceuticals, food, and the environment.

Mapping of available health research and development data: what's there, what's missing, and what role is there for a global observatory?

The need to align investments in health research and development (R&D) with public health demands is one of the most pressing global public health challenges. We aim to provide a comprehensive description of available data sources, propose a set of indicators for monitoring the global landscape of health R&D, and present a sample of country indicators on research inputs (investments), processes (clinical trials), and outputs (publications), based on data from international databases. Total global investments in health R&D (both public and private sector) in 2009 reached US$240 billion.

Health innovation networks to help developing countries address neglected diseases.

Gross inequities in disease burden between developed and developing countries are now the subject of intense global attention. Public and private donors have marshaled resources and created organizational structures to accelerate the development of new health products and to procure and distribute drugs and vaccines for the poor. Despite these encouraging efforts directed primarily from and funded by industrialized countries, sufficiency and sustainability remain enormous challenges because of the sheer magnitude of the problem.
