With the growing outbreak of COVID-19, also known as the coronavirus, universities around the U.S. are canceling in-person classes, clamping down on travel, and sending students home. Protecting the health of students and staff, and limiting community transmission, is the most important priority. After taking care of emergency measures, universities need to be making administrative…

There is one golden rule for flying with an infant or toddler: Do whatever it takes to get through the flight peacefully with no harm done. Every parent knows this means relaxing their standards. Planting your kid in front of an iPad screen or giving them not so healthy treats might not win you a…

Over 200 colleges and universities have closed in the United States due to the coronavirus pandemic. Some have canceled in-person classes for the rest of the spring 2020 semester, while others have canceled graduation. Universities are trying to make decisions in a fluid and unprecedented environment. Professors and instructors face their own challenges as they…

As cases of coronavirus (COVID-19) in the United States rise, more and more states have adopted shelter-in-place orders to curtail the pandemic. The disruption to most Americans’ daily lives has been drastic and sudden—and perhaps one of the most dramatic shifts was education’s move to a virtual setting. Even before the current pandemic forced school closures,…

Universities around the country are dealing with health concerns as their first priority, and keeping instruction going—even if imperfectly—as the second priority. After dealing with these immediate issues, the next concern is fear of collapsing revenue. Health and instruction deserve every bit of effort going into them. The extent of worry about collapsing revenue isn’t…

One year after Operation Varsity Blues, and in the midst of one of the greatest crises higher education has ever seen, college admissions and access have never been more important. A college degree has long been seen as a ticket into the middle class, but it is increasingly clear that not all institutions lead to…

This week in Class Notes: California's shelter-in-place order was effective at mitigating the spread of COVID-19. Asian Americans experience significant discrimination in the Harvard admissions process. The U.S. tax system is biased against labor in favor of capital, which has resulted in inefficiently high levels of automation. Our top chart shows that poor workers are much more likely to keep commuting in…

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.

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.

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.

With the Russia investigation and impeachment behind him, President Trump finally may feel empowered to engage with Russian President Vladimir Putin and pursue an arms control deal.

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.”

A simplified nuclear exchange model demonstrates that China’s ability to launch a successful nuclear retaliatory strike in response to an adversary’s nuclear first strike has been and remains far from assured. This study suggests that China’s criterion for effective nuclear deterrence is very low.

Major changes are taking place in urban transportation and service delivery. There are shifts in car ownership, the development of ride-sharing services, investments in autonomous vehicles, the use of remote sensors for mobile applications, and changes in package and service delivery. New tools are being deployed to transport people, deliver products, and respond to a…

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…

There are few silver linings to the COVID-19 pandemic, but free-flowing traffic is certainly one of them. For the essential workers who still must commute each day, driving to work has suddenly become much easier. The same applies to the trucks delivering our surging e-commerce orders. Removing so many cars from the roads has even…

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…

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

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,…

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.

As the divergent experiences of the US and South Korea show, testing can be the difference between disease containment and catastrophe. Rather than relying on national governments to ensure the rapid development, production, and deployment of diagnostics during outbreaks, the world needs a global coordinating platform.
