Visualizing the Data: The Evolution of Trade Tensions in Metals and Minerals Markets 18 January 2018 — 4:30PM TO 6:00PM Anonymous (not verified) 19 December 2017 Chatham House, London

Over the past decade, producer countries such as South Africa, Zambia, Indonesia, the DRC and, most recently, Tanzania have restricted exports of unprocessed precious metals, copper, nickel, cobalt and other minerals in an attempt to support, or create, downstream processing industries and jobs or increase revenues. These moves have invariably created tensions with trading partners. Research suggests that export restrictions are not the best way to achieve such policy objectives and can instead harm the producer country’s economy and undermine the functioning of international metals and minerals.

Drawing on OECD and Chatham House research on resource trade, the speaker will present analysis and data visualizations exploring the drivers of past export restrictions and their political and economic impacts. They will also consider how the drivers of ‘resource nationalist measures’ are changing, whether and where export restrictions might present strategic and economic risks in the current context, and the extent to which producer and consumer governments and international governance mechanisms are prepared to address them.

Attendance at this event is by invitation only.

The Impact of Brexit on Energy Transformation in the UK and EU 28 March 2019 — 8:15AM TO 9:45AM Anonymous (not verified) 3 December 2018 Chatham House | 10 St James's Square | London | SW1Y 4LE

The UK’s decision to leave the EU will fundamentally reshape many of the UK’s policies and its relations with countries around the world. For energy and climate, the changes could be significant and will need to be managed carefully to secure ongoing investment, stable energy prices and ambitious climate objectives. The UK’s departure will also affect the balance of political support for climate and energy policies with the EU institutions and potentially impact upon regional initiatives.

This roundtable will discuss:

• The impact on the energy sector of Brexit during the transition period through until December 2020 including the operation of interconnectors and access to the Internal energy market, ongoing engagement in European research collaboration and the replacement of European financial resources.
• The possible opportunities and risks for the UK’s energy sector in 2021 and beyond.
• The implications of Brexit on the EU’s energy and climate policy.

The roundtable will discuss the role of the public and business in shaping the future deal as it will need to be ratified by the parliaments of all member states.

Attendance at this event is by invitation only.

Power Sector Transformation, New Market Dynamics and Geopolitical Implications 7 November 2018 — 8:00AM TO 9:30AM Anonymous (not verified) 6 December 2018 Chatham House | 10 St James's Square | London | SW1Y 4LE

The global electricity sector is experiencing profound change due to a confluence of technological innovation, environmental policies and regulatory reform. The effect is most obvious in the EU28, Australia and parts of North America.

However, this is just the beginning and the success of the next phase of electricity sector transformations hinges on enhancing system flexibility to facilitate unhindered low-cost deployment of renewables. It remains to be seen how utilities will seek to navigate this second phase of electricity transformations.

This session starts with a presentation and discussion that focuses on:

• Public and private sector risks of the transformation of the power sector, changes in generation mix and their implications for supply chain, employments and investment patterns.
• The role of government and the regulatory framework in light of changing market structure, new entrants and big data.
• Wider geopolitical issues including the implication for fossil fuel producers and the rise in demand for new materials and changes in land use.
• The possible implications on the power sector on the electrification of heat and transport.

The discussion then moves to the speed of transformation and what this means for existing and new market actors.

Impact of the US Election on Global Climate Politics 25 November 2020 — 1:00PM TO 2:00PM Anonymous (not verified) 16 November 2020 Online

Panellists discuss how Joe Biden’s victory will impact international efforts to tackle climate change. Will climate finally become a common area for global cooperation?

Joe Biden’s victory over Donald Trump is already having a positive impact on international efforts to tackle climate change. Leaders from across the world, including the UK, Canada, Australia and Fiji, have used their first messages to the President-elect to draw attention to the climate crisis.

Biden has promised to re-join the global community in its commitment to the Paris Agreement – but this could be the easy part. More difficult will be whether and how Biden is able to deliver his ambitious climate plan, and how effectively he is able to integrate climate change into foreign policy efforts and national security strategies.

Global climate action has also moved forward in the last four years. The European Union recently pledged to become climate neutral by 2050, and China, Japan and South Korea have committed to achieving carbon neutral economies.

How will the US re-enter this global landscape of distributed leadership and what difficulties does it face? Will the US be willing to work within a competitive partnership with the EU and China? How will Biden’s win change the dynamic of COP26 next year? 

Climate action and gender equality: Can we close the gap on one without the other? 8 March 2021 — 2:30PM TO 4:00PM Anonymous (not verified) 15 February 2021 Online

In partnership with the COP26 presidency, policymakers and experts examine the interrelationship between gender equality and climate action, and highlight innovative examples of policy and practice from around the world.

Marking International Women’s Day, this event organized by the COP26 presidency in partnership with Chatham House, will explore how gender equality and climate action go hand-in-hand. The agreement of the Gender Action Plan (GAP) at COP25 sent the message that the time for gender-responsive climate action is now.

This will be a unique opportunity to hear from policymakers and civil society leaders discussing whether enough is being done, as well as highlighting cutting-edge work around the world and suggesting what the future could hold.

The event will be livestreamed on this event page.

Sand: Monitoring and management for a sustainable future 2 March 2021 — 1:00PM TO 2:00PM Anonymous (not verified) 18 February 2021 Online

In partnership with the Global Sand Observatory Initiative, this event outlines the sand challenge, what actions are currently underway to address it, and what else needs to be done.

Please complete your registration on Zoom:

After water, sand is the raw material that the world consumes in the greatest quantity. It is no exaggeration to say that fine sand and coarser materials – the medium-to-coarse-grained pebbles, gravel and rock fragments used in construction – are the building blocks of the modern world.

When bound with cement, sand becomes concrete; when mixed with bitumen, it becomes asphalt; and when heated, it becomes glass. Without sand, we would have no highways, high-rises or high-speed trains. Yet sand – which is used here as shorthand for sand, gravel and crushed rock together – is a resource that is both abundant and finite.

In global terms, it is abundant, especially when compared with many other raw materials, albeit often not available close to where it is needed. It is finite in that the rate at which we are using it far exceeds the natural rate at which it is being replenished by the weathering of rocks by wind and water.

Industrialization, population growth and urbanization have fuelled explosive growth in the demand for sand. Precise data on sand extraction are hard to come by and the lack of data compounds the challenge of managing the resource sustainably.

However, the UN estimates that overall extraction could be in the region of 40 billion tonnes per year, driven primarily by construction sector demand. That equates to 18 kilograms of sand each day for every person on the planet and signals how strategically important these resources are for future sustainable development. Post-COVID-19 recovery investment in infrastructure, digital technologies, tourism and other economic activities are dependent on sand resources.

Current efforts to improve the management of sand resources at local, national and global levels are uneven. This is partly due to unique geological features and geography, but also differences in local manifestations of the ‘sand challenge’, national and regional demand for sand resources, as well as capacities to enforce or implement best practice assessment procedures, extractive practices, environmental management and restoration requirements.

We must put stronger conditions in place for a rapid, just and scaled transition to sustainable sand management. But where to focus our efforts for the greatest positive impact?

Youth voices on climate action 22 April 2021 — 12:30PM TO 2:00PM Anonymous (not verified) 22 March 2021 Online

To celebrate Earth Day, youth activists, local change-makers, innovators and entrepreneurs discuss opportunities and challenges for youth-led climate activism.

Young people will bear the brunt of the intensifying impacts of climate change over time. Facing this challenge, youth around the world have emerged at the forefront of climate activism at an unprecedented scale.

School strikes, marches, and declarations complement youth engagement in diplomacy, technology, science, and law. Providing a platform for young people involved in climate action at the local, national and global levels is essential to promote collaboration, generate new policy ideas, and demand accountability from political and business leaders.

Panellists engage in critical conversation about COP26; global leadership in climate mitigation, adaptation, and finance; and how to develop the full potential of youth-led global initiatives going forward.

From local to global: A roadmap for US climate action 14 April 2021 — 6:30PM TO 8:00PM Anonymous (not verified) 28 March 2021 Online

Ahead of Biden’s Earth Day Summit, panellists discuss a range of climate issues, from city-level climate management to the international security implications of climate deals.

On their first day in office, the Biden-Harris administration sent a strong message to Americans and allies by rejoining the Paris Agreement. Experienced climate and environmental leaders were appointed to senior leadership roles as part of a ‘whole of government approach’ to climate action.

Although decisive action is welcomed by many Americans and international partners, the divided domestic perspectives on climate and a changed international landscape pose significant challenges.

Ahead of the Earth Day Summit on April 22, an event hosted by Joe Biden to mark America’s formal return to global climate talks, panellists discuss a range of climate issues, from city-level climate management to the international security implications of climate deals.

• How will post-COVID domestic priorities and policy influence the international approach of the US to climate action?
• How will US policy, both foreign and domestic, need to respond to the security and geopolitical elements posed by climate change?
• What actions are needed during the upcoming Earth Day Summit for the US to establish credibility as a climate leader?
• What shape are key debates taking on US-China climate relations ahead of COP 26, and how might climate issues be approached in relation to wider geopolitical tensions?

Prioritizing equity and justice in climate action 30 June 2021 — 11:00AM TO 12:00PM Anonymous (not verified) 10 June 2021 Online

London Climate Action Week event: Why understanding equity and justice is essential to the ability to meaningfully inform climate politics.

Citizen-led climate activism is demonstrating the need to think about climate change ‘not just as a problem for science to solve’ but also as a problem of equity, human rights and justice.

The disproportionate impacts of climate change on the poor and the marginalized across the world means that understanding equity and justice is essential for the ability to meaningfully inform climate politics.

Excluding these issues risks ignoring, or intentionally omitting, the consequences of policies, tools and frameworks on those who are most likely to face the severe costs of any climate action or inaction.

In a pivotal year for climate decision-making, this event explores the necessity of equity and justice in climate action and how the world can move the political conversation to one that is more inclusive.

The speakers explore how communities themselves articulate the justice dimensions of climate change and how fairness can create a greener future for current and future generations.

This event is being hosted as a part of Strengthening Climate Diplomacy, a series of events from Chatham House during London Climate Action Week 2021.

Cities as climate leaders: Progress and ambition 1 December 2021 — 12:00PM TO 1:00PM Anonymous (not verified) 16 November 2021 Online

This panel discusses the progress cities have already made, whether progress at COP26 was enough, and what more needs to be done to scale action and ambition internationally.

Cities are critical to tackling the pressing environmental challenges of our time. While they now account for an estimated 75 per cent of global CO2 emissions, cities also offer a unique opportunity for devolved leadership on climate action. At the recent COP26, some significant progress was made in elevating cities’ position on climate action with a flurry of announcements and commitments.

For example, more than 1,000 cities are now committed to the Cities Race to Zero and C40’s Clean Construction Declaration saw multiple cities committing to at least halving emissions from initial construction of buildings by 2030. A raft of financing commitments were also made to improve urban resilience in the face of climate change.

This builds on existing momentum before COP26. Over 50 world cities are now on track to meet Paris Agreement and the Marrakech Partnership is further enabling collaboration between governments and cities within the UNFCCC processes.

Therefore, how we design, build, govern and use our urban places will be a key factor for decarbonization and climate change adaptation.

On the back of COP26, this panel brings together leaders from across urban development sectors to discuss the progress cities have already made, whether progress at COP26 was enough, and what more needs to be done to scale action and ambition internationally. 

Loss and damage: Where are we now and what happens next? 25 January 2022 — 1:00PM TO 2:00PM Anonymous (not verified) 17 January 2022 Online

This event discusses the progress of the loss and damage agenda within climate negotiations. 

Loss and damage refers to harms and destruction caused by climate change impacts that cannot be avoided through mitigation or adaptation.

While it has gained increasing recognition in international climate change negotiations, turning the concept of loss and damage into tangible action for climate-vulnerable countries has been contentious.

Loss and damage is interwoven with issues of fairness and equity. The issue is highly disputed due to its connection with the historical responsibility of developed countries in causing climate change, as well as associated calls for compensation from developing countries.

At COP26, Scotland became the first government to pledge funds for loss and damage for countries in the Global South. However, most climate-vulnerable countries left disappointed by the failure of the Glasgow Climate Pact to secure the establishment of a dedicated loss and damage financing facility.

Developing countries have made it clear that they will continue to push for a new financing facility in the Glasgow Dialogue, a set of international discussions on loss and damage kicking off in June.

The Environment and Society Discussion Series is hosting two events on loss and damage ahead of that date. This first event outlines the key debates and discuss what progress has been made on advancing the loss and damage agenda within climate negotiations to date.

The second event focuses on solutions and possible ways forward, looking ahead to the COP27 negotiations in Egypt later in 2022, where loss and damage is expected to be a high-profile agenda item.

Feminist solutions to the climate crisis 8 March 2022 — 11:00AM TO 12:00PM Anonymous (not verified) 1 March 2022 Online

This International Women’s Day panel explores intersectional feminist approaches to solving the climate crisis.

Gender inequality and climate change are closely intertwined. Due to their different and unequal social roles and status, women, girls and people of marginalised genders are disproportionately affected by climate change impacts, also differentiated by factors such as age, race, ability and location.

They are also leading innovative solutions to climate change at all levels, especially in frontline communities. Yet as the Glasgow Women’s Leadership statement highlighted at COP26, there is still a lack of momentum for prioritising their knowledge, tools and leadership in climate policy and action.  

This panel considers what feminist approaches can bring to climate change communication and movement building, spotlighting a range of local and regional gender-responsive climate initiatives. It also discusses concrete examples of feminist and gender-responsive policies to address climate change, such as the Feminist Green New Deal.

The panel highlights the critically important work being carried out by diverse feminist activists and researchers, and how the audience can centre gender and social equality in their work on climate change.  

Climate finance and conflict dynamics on the road to COP27 21 September 2022 — 1:00PM TO 2:00PM Anonymous (not verified) 9 September 2022 Online

Stakeholders discuss the role of conflict and conflict sensitivity in climate finance and action.

With climate change, fragility and conflict challenges worsening, the role of international climate finance is more urgent than ever.

From the implementation of climate finance and who it reaches to the rush for renewable energy, the inclusion of conflict analysis and conflict sensitivity principles often remain absent from climate finance discussions and planning.

With COP27 around the corner and for the occasion of International Peace Day, stakeholders ranging from government representatives to climate activists discuss their perspectives on the role of conflict and conflict sensitivity as part of climate finance and action.

This event was organized in partnership with International Alert.

Food system transformation: A blind spot for climate and biodiversity action? 20 October 2022 — 12:00PM TO 1:00PM Anonymous (not verified) 5 October 2022 Chatham House and Online

How can COP27 and COP15 accelerate the agenda for sustainable food systems and land use?

Tackling the dual crises of climate change and biodiversity loss requires extraordinary levels of action at an unprecedented speed. Agriculture is the biggest user of land, the biggest source of methane emissions, a major contributor to total greenhouse gas emissions and the leading driver of biodiversity loss.

Anything short of a food system transformation puts climate and biodiversity objectives in peril. However, governments have not yet produced credible pathways and strong policies for tackling our growing ‘foodprint’ – the negative impacts of what we grow and eat.

In advance of COP27 in Sharm El-Sheikh for climate and COP15 in Montreal for biodiversity, Chatham House has published a new briefing paper which examines aligning food systems with climate and biodiversity targets.

The paper reviews the climate and biodiversity policy landscape to 2030, with a focus on land-based aspects and the inclusion of food and agriculture. The paper highlights serious conflicts between the impacts of the food system and goals to protect and restore biodiversity and mitigate climate change.

In light of this, opportunities for joined-up action on food, climate and biodiversity are identified, including three key steps for countries to take this decade to produce suitably ambitious and effective policies across the climate–biodiversity–food nexus.

This event brings together leading voices from the international policy arenas for climate and biodiversity to react to the briefing paper and discuss how COP27 and COP15 can accelerate the agenda for sustainable food systems and land use.

China, Liu Xiaobo and the New Reality of Human Rights Expert comment sysadmin 18 July 2017

Liu Xiaobo, Chinese Nobel laureate and human rights campaigner, died on 13 July while serving an 11-year prison sentence for ‘subversion’. Steve Tsang tells Jason Naselli that the reaction to Liu’s death reflects the growing confidence of the Chinese government that it can ignore Western criticism.

What does the Communist Party’s handling of the case of Liu Xiaobo tell us about its approach to dissidents and freedom of speech in the Xi era?

What it tells us is the party is tightening control much more than before. The Liu Xiaobo case shows that the party is not comfortable with people asking for the constitution of the People’s Republic of China to be enforced. Charter 08, for which Liu Xiaobo was jailed, ultimately amounts to asking for the rights of Chinese citizens, as articulated in the constitution, to be fully implemented. That resulted in Liu Xiaobo being incarcerated.

But what is really important isn’t so much that the party is tightening its control – that is happening anyway. What is more important is that the party is not that worried about how the Liu Xiaobo case affects international opinion.

If that’s the case, what lessons should countries looking to trade with China but concerned about human rights abuses take from Liu’s case?

We haven’t seen any major Western country come out to strongly and clearly hold the Chinese government to account over Liu Xiaobo’s human rights situation. A few leading governments have asked for Liu Xiaobo’s widow to be allowed to choose to stay or leave China. But so far there is no indication of any government backing that up with anything concrete.

That is very weak support for human rights in China. And it reflects a new reality: of the unwillingness of leading democracies to challenge the Chinese government on human rights matters, and the confidence on the part of the Chinese government to simply ignore what the rest of the world may think about it.

Given that there has been much discussion of China taking a larger global leadership role in the wake of an inward political turn in the US, what are the implications of Liu’s case for China’s global standing?

The implications are really small. There is a stronger expectation and desire to see China playing a global role because Donald Trump has damaged the standing of the United States as a global leader. It is not because of something that the Chinese government has done; it’s because of Trump.

That wider context hasn’t changed. So the Chinese government’s calculation is that the negative international reaction to Liu Xiaobo’s death will blow over in a matter of days – at worst, a couple of weeks – and then things will get back to normal.

There is no serious reason to believe that the Chinese government is wrong in their calculation. At the moment, the major Western countries are focusing on the economic relationship, and doing what they have to do pro forma about human rights issues in China. No major Western government is going to say that they are going to reconsider a major trade deal with China because of how Liu Xiaobo or his family has been treated. The Chinese government knows that and they act accordingly.

Moving on from the international reaction, how does Liu’s situation resonate within China?

Most Chinese don’t even know who Liu Xiaobo is. Within China, you cannot even search Liu Xiaobo’s name, or any permutation of Liu Xiaobo’s name, or the English initials of Liu Xiaobo. Anything potentially about or related to Liu Xiaobo is being censored.

Some things still get through; the ingenuity of a lot of bloggers is infinite. But most Chinese don’t even know what happened to Liu Xiaobo, or if they do, they mostly see him as a shill of the Western world trying to infiltrate and destabilize China.

If Western governments won’t engage China over human rights, what implications does that have for the global treatment of human rights as China becomes a bigger global player?

You can ‘engage’ in the sense of raising the issue with the Chinese authorities, as indeed the UK government and the German government have done, for example. But they haven’t actually taken any concrete steps.

The type of engagement where Western governments would get the Chinese government to demonstrate that something concrete was being done to improve the human rights situation – that era has gone. It is not going to come back in the foreseeable future. And therefore, the situation in terms of human rights in China will not be improving in the foreseeable future.

But what is more significant is how the Chinese government is asserting itself and dealing with domestic and international challenges, including on human rights issues. For many other countries around the world, China is showing an example for how to deal with the West. They don’t see it as being negative; they see it in positive terms.

There are still more countries in the world that abuse human rights than respect human rights. Most of those governments are pleased to see what the Chinese government has done in terms of how it handles the West.

Combatting Human Trafficking: The Situation in East Asia 16 September 2019 — 10:30AM TO 5:30PM Anonymous (not verified) 30 August 2019 Taipei, Taiwan

In 2017, there were an estimated 40.3 million victims of modern slavery worldwide. The prevalence for individuals to fall victim to forced labour practices is highest in the Asia-Pacific region where four out of every 1,000 people have been found to be victims of forced labour and labour trafficking. Many of these victims end up in the more developed economies of East Asia as destination countries of labour trafficking. Such cases are, however, often under-reported and under-detected, largely owing to a lack of a coherent response to trafficking across the sub-region.

At this roundtable, organized in partnership with the Taiwan Foundation for Democracy, the Taiwan-Asia Exchange Foundation and the University of Portsmouth, participants will discuss emerging anti-trafficking practices from a regional perspective including legal and policy frameworks and the role of business and recruitment agencies.

Attendance at this event is by invitation only.

Is Myanmar Running Out of Time? 17 February 2020 — 1:00PM TO 2:00PM Anonymous (not verified) 10 January 2020 Chatham House | 10 St James's Square | London | SW1Y 4LE

Just a few years ago the West was celebrating what appeared to be the conclusion of a quarter-century long contest between Myanmar’s democrats and a military dictatorship. Today, the country stands charged with genocide at the International Court of Justice, with Aung San Suu Kyi leading the defence. Is Myanmar a democratic transition gone awry? Or something else entirely?

The speaker will argue that Myanmar is not the simple morality tale often portrayed. It has instead become the stage for some of the world’s most pressing challenges such as climate change, explosive inequality and rising populism, the impact of social media; and the rise of China as the next global superpower.

In this context, are 20th century democratic institutions and free-market reforms the correct remedy for a country plagued by the legacies of colonialism, decades of civil war, tyranny and a predatory economic system? The speaker will offer a prognosis for Myanmar’s future, assessing the question of whether it will become Asia’s next failed state.

This event will be held off the record.

Bangladesh: The Trade-Off Between Economic Prosperity and Human Rights 11 March 2020 — 1:00PM TO 2:00PM Anonymous (not verified) 28 February 2020 Chatham House | 10 St James's Square | London | SW1Y 4LE

Bangladesh’s recent gains in economic and social indices, set against its record of corruption and poor civil rights, has at times been termed the ‘Bangladesh Paradox’. Yet this label is overly simplistic; the current situation proves that these trends can coexist.

The Awami League government, in power since 2009, has increased political stability, delivered unprecedented economic and social advances, and adopted a counter-terrorism strategy to stamp out extremist groups. At the same time, it is criticized for curbing civil rights and failing to hold credible elections. However, as the two previous regimes have demonstrated, the rights situation is unlikely to improve even if the Awami League were replaced.

How did worsening rights become a feature of the state irrespective of its political dispensation? An unresolved contest between political and non-political state actors may hold the key to that puzzle. The perils of the current dispensation have recently manifested in weakening economic indicators, which jeopardize the very stability and social progress for which the country has garnered much praise.

Math's connection with cooking extends beyond the mathematical constant that sounds like a dessert. For example, using differential equations to model fluid flow and heat transfer, research teams have found how spaghetti curls as it's cooked, how to rotate a pan to make the perfect crepe (thin pancake), and the temperature setting to get the perfect steak. Mathematics helps understand cooking, and parallels it in that following a recipe can lead to good results, but asking questions like "What if we tried this?" can lead to a masterpiece. Eugenia Cheng talks about the mathematics of cooking and baking.

We've seen that the availability of hospital beds is important during a pandemic, and it's important during normal times as well. Whether it's for emergency medical help or for a scheduled procedure (for example, chemotherapy), access to hospital space, staff, and equipment can be a matter of life and death. Mathematics helps medical center staff manage their resources more efficiently so that they are available when needed. An optimization technique called integer programming is used along with tools from statistics, probability, and machine learning to create better schedules for operating rooms, treatment centers, and the people who staff them. David Scheinker talks about the mathematics involved in hospital operations.

Math may sometimes seem as if it's comprised of countless meaningless unconnected exercises, but in reality, it's much more. It's figuring out how to do something, and, even better, why something works the way it does. The math you're doing now can open doors for you so that you can answer deep questions yourself about a subject or idea that you're interested in. Give those questions a shot and perhaps someday also help others solve their problems. Five mathematicians (Alexander Diaz-Lopez, Trachette Jackson, Francis Su, Erika Tatiana Camacho, and Deanna Haunsperger) talk about what mathematics means to them.

Malena Espanol explains how she and others use linear algebra to correct blurry images. Imagine snapping a quick picture of a flying bird. The image is likely to come out blurry. But thanks to mathematics, you might be able to use software to improve the photo. Scientists often deal with blurry pictures, too. Linear algebra and clever numerical methods allow researchers to fix imperfect photos in medical imaging, astronomy, and more. In a computer, the pixels that make up an image can be represented as a column of numbers called a vector. Blurring happens when the light meant for each pixel spills into the adjacent pixels, changing the numbers in a way that can be mathematically represented as an enormous matrix. But knowing that matrix is not enough if you want to reconstruct the original (non-blurry) image.

Stacey Finley from University of Southern California discusses how mathematical models support the research of cancer biology. Cancer research is a crucial job, but a difficult one. Tumors growing inside the human body are affected by all kinds of factors. These conditions are difficult (if not impossible) to recreate in the lab, and using real patients as subjects can be painful and invasive. Mathematical models give cancer researchers the ability to run experiments virtually, testing the effects of any number of factors on tumor growth and other processes — all with far less money and time than an experiment on human subjects or in the lab would use.

Imelda Flores Vazquez from Econometrica, Inc. explains how economists use mathematics to evaluate the efficacy of health care policies. When a hospital or government wants to adjust their health policies — for instance, by encouraging more frequent screenings for certain diseases — how do they know whether their program will work or not? If the service has already been implemented elsewhere, researchers can use that data to estimate its effects. But if the idea is brand-new, or has only been used in very different settings, then it's harder to predict how well the new program will work. Luckily, a tool called a microsimulation can help researchers make an educated guess.

Dr. Abiy Tasissa of Tufts University, discusses the mathematics he and colleagues used to study particle collider data, including optimal transport and optimization. Collider physics often result in distributions referred to as jets. Dr. Tasissa and his team used "Earth Mover's Distance" and other mathematical tools to study the shape of jets. "It is interesting for me to see how mathematics can be applied to study these fundamental problems answering fundamental equations in physics, not only at the level of formulating new ideas, which is, in this particular case, a notion of distance, but also how the importance of designing fast optimization algorithms to be able to actually compute these distances," says Dr. Tasissa.
