New technologies are transforming the transportation sector. These include autonomous vehicles, ride-sharing services, remote sensors, and unmanned aerial systems, among other developments. As is true with many technologies, however, the products have advanced faster than the policies and regulations surrounding them. On September 10, The Center for Technology Innovation hosted a panel discussion featuring Brookings…

Think about a day in the life of a typical office worker in the Washington, D.C. area. They take Metro to get to the office on time, order lunch to be delivered from the busy restaurant down the street, purchase tickets to a weekend matinee film, and call a Lyft home as hockey fans swarm…

The 2016 presidential election felt like a watershed moment for federal infrastructure reform. For the first time in decades, both the Democratic and Republican presidential candidates made infrastructure a central component of their platforms. Their proposals reflected years of consistent calls for congressional action from groups representing cities, states, and industries—all of whom welcomed the…

Cars are a fact of life for the vast majority of Americans, whether we’re commuting to work or traveling to just about anywhere. But a new development outside Phoenix is looking to change that. Culdesac Tempe, a 1,000-person rental community, aims to promote a new type of walkable neighborhood by banning residents from driving or…

It was only a generation ago when many Americans left downtowns for dead. From New York to Chicago to Los Angeles, residents fled urban cores in droves after World War II. While many businesses stayed, it wasn’t uncommon to find entire downtowns with little street life after 5:00 PM. Many of those former residents relocated…

The COVID-19 pandemic has brought economic and social activity around the world to a near standstill. As a result, carbon dioxide emissions have declined sharply, and the skies above some large cities are clean and clear for the first time in decades. But “degrowth” is not a sustainable strategy for averting environmental disaster. Humanity should protect…

On April 13, 2020, Suzanne Maloney discussed "Why the Middle East Matters" via video conference with IHS Markit.

Following President Trump’s mid-March declaration that the COVID-19 outbreak constituted a “national emergency,” the Department of Defense (DoD) moved swiftly to implement travel restrictions for DoD employees intended to “preserve force readiness, limit the continuing spread of the virus, and preserve the health and welfare” of military service members, their families and DoD civilians. In…

With the saga over the U.S.S. Teddy Roosevelt aircraft carrier starting to fade from the headlines, a larger question about the American armed forces and COVID-19 remains. How will we keep our military combat-ready, and thus fully capable of deterrence globally, until a vaccine is available to our troops? It will also be crucial to…

Two years after the National Defense Strategy was published, it’s time to take stock of where the Army stands. On an immediate level, the age of COVID-19 presents the Army with an unprecedented set of challenges. From ensuring high levels of readiness to keeping up recruitment, the pandemic has forced the Army to adapt quickly…

The COVID-19 pandemic is among the most serious challenges confronting the globe since World War II. Its projected human and economic costs are devastating. While the armed forces of the United States will rise to this challenge as they have others, the Department of Defense will not stop planning for long-term threats to America's security,…

Decades of space activity have littered Earth’s orbit with orbital debris, popularly known as space junk. Objects in orbit include spent rocket bodies, inactive satellites, a wrench, and even a toothbrush. The current quantity and density of man-made debris significantly increases the odds of future collisions either as debris damages space systems or as colliding…

The consequences of the novel coronavirus pandemic stretch across the entirety of government services. Major police agencies have reported absentee rates as high as 20% due to officers who are either themselves afflicted with the virus or in need of self-quarantine. Reported crimes are generally down in America’s cities as a result of the many…

In games such as chess and Go, artificial intelligence has repeatedly demonstrated its ability to outwit the experts. Ad networks and recommendation engines are getting eerily good at predicting what consumers want to buy next. Artificial intelligence, it seems, is changing many aspects of our lives, especially on the internet. But what has been described…

How have the experiences, representation, and recognition of women in the military transformed, a century after the ratification of the 19th Amendment to the U.S. Constitution? As Brookings President and retired Marine Corps General John Allen has pointed out, at times, the U.S. military has been one of America’s most progressive institutions, as with racial…

The U.S. military’s prevailing norms of military professionalism are poorly suited to meet today’s civil-military challenges. They undermine the military’s nonpartisan and apolitical ethos, weaken civilian leaders' control of military activity, and undercut the country’s strategic effectiveness in armed conflict.

In the unintuitive world of nuclear weapons strategy, it’s often difficult to identify which decisions can serve to decrease the risk of a devastating nuclear conflict and which might instead increase it. Such complexity stems from the very foundation of the field: Nuclear weapons are widely seen as bombs built never to be used. Historically, granular—even seemingly mundane—decisions about force structure, research efforts, or communicated strategy have confounded planners, sometimes causing the opposite of the intended effect.

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.

Realistic, creative vulnerability assessment and testing are critical to finding and fixing nuclear security weaknesses and avoiding over-confidence. Both vulnerability assessment and realistic testing are needed to ensure that nuclear security systems are providing the level of protection required. Systems must be challenged by experts thinking like adversaries, trying to find ways to overcome them. Effective vulnerability assessment and realistic testing are more difficult in the case of insider threats, and special attention is needed. Organizations need to find ways to give people the mission and the incentives to find nuclear security weaknesses and suggest ways they might be fixed. With the right approaches and incentives in place, effective vulnerability assessment and testing can be a key part of achieving and sustaining high levels of nuclear security.

Nuclear security is never finished. Nuclear security measures for protecting all nuclear weapons, weapons-usable nuclear materials, and facilities whose sabotage could cause disastrous consequences should protect against the full range of plausible threats. It is an ongoing endeavor that requires constant assessment of physical protection operations and reevaluation of potential threats. One of the most challenging areas of nuclear security is how to account for the impact–positive and negative—of non-nuclear emerging technologies. The amended Convention on the Physical Protection of Nuclear Material (amended CPPNM) states it should be reviewed in light of the prevailing situation, and a key part of the prevailing situation is technological evolution. Therefore, the upcoming review conference in 2021, as well as any future review conferences, should examine the security threats and benefits posed by emerging technologies.

Civil society has played a very important role in nuclear security over the years, and its role could be strengthened in the future. Some nuclear organizations react against the very idea of civil society involvement, thinking of only one societal role—protesting. In fact, however, civil society has played quite a number of critical roles in nuclear security over the years, including highlighting the dangers of nuclear terrorism; providing research and ideas; nudging governments to act; tracking progress and holding governments and operators accountable; educating the public and other stakeholders; promoting dialogue and partnerships; helping with nuclear security implementation; funding initial steps; and more. Funding organizations (both government and non-government) should consider ways to support civil society work and expertise focused on nuclear security in additional countries. Rather than simply protesting and opposing, civil society organizations can help build more effective nuclear security practices around the world.

Participants at the final Nuclear Security Summit in 2016 agreed on “action plans” for initiatives they would support by five international organizations and groups—the International Atomic Energy Agency, the Global Initiative to Combat Nuclear Terrorism, INTERPOL, the United Nations, and the Global Partnership Against the Spread of Weapons and Materials of Destruction. These institutions were supposed to play key roles in bolstering ongoing nuclear security cooperation after the summit process ended. The action plans were modest documents, largely endorsing activities already underway, and there have been mixed results in implementing them. To date, these organizations have not filled any substantial part of the role once played by the nuclear security summits.

The opening of the British archives has seen historians uncover the secrets of the UK's nuclear weapons programme since the 1990s. While a growing number have sought to expose these former secrets, there has been less effort to consider government secrecy itself. What was kept a secret, when and why? And how and why, notably from the 1980s, did the British government decide to officially disclose greater information about the British nuclear weapons programme to Members of Parliament, journalists, defence academics and the tax-paying general public.

A nuclear explosion detonated anywhere by a terrorist group would be a global humanitarian, economic, and political catastrophe. The current COVID-19 pandemic reminds us not to ignore prevention of and preparation for low-probability, high-consequence disasters. For nuclear terrorism, while preparation is important, prevention must be the top priority. The most effective strategy for keeping nuclear weapons out of the hands of terrorists is to ensure that nuclear materials and facilities around the world have strong and sustainable security. Every president for more than two decades has made strengthening nuclear security around the globe a priority. This includes the Trump administration, whose 2018 Nuclear Posture Review states: “[n]uclear terrorism remains among the most significant threats to the security of the United States, allies, and partners.”

The authors investigate how the executives of the two largest research institutes for photovoltaic technologies — the National Renewable Energy Laboratory (NREL) in Golden, USA and the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) in Freiburg, Germany — have made use of public framing to secure funding and shape the technological development of solar photovoltaic (PV) technologies. The article shows that the executives used four framing dimensions (potential, prospect, performance, and progress) and three framing tactics (conclusion, conditioning, and concession), and that the choice of dimensions and tactics is tightly coupled to the characteristics of the specific technologies pursued by the research institutes.
