Science, Technology, and Public Policy

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

To accelerate the global transition to a low-carbon economy, all energy systems must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, clean hydrogen – defined as hydrogen produced from water electrolysis with zero-carbon electricity – has captured increasing political and business momentum as a versatile and sustainable energy carrier in the future carbon-free energy puzzle.

Joel Clement writes that because the Biden administration  has moved to repair the damage done by the Trump administration, colleagues from around the global Arctic are optimistic once again about partnering with America on solutions to regional crises .

No great breakthroughs or dramatic developments were expected at the Biden-Putin summit, and none was achieved. But the message was clear: There is a new sheriff in town. Putin noticed, describing Biden as very different from Trump—experienced, balanced, and professional.

Bruce Schneier and Tarah Wheeler describe the future of war as cyberwar. They advise that if weapons and systems aren't secure, don't even bother bringing them onto the battlefield.

Tarah Wheeler critiques a new book, This Is How They Tell Me The World Ends by Nicola Perlroth, and concludes that it gets the policy recommendations right while making technical errors that could undermine trust in its conclusions.

Bruce Schneier recommends that the United States improve government software procurement. Scrutiny cannot end with purchase: Security requirements need to be monitored throughout the software's life cycle, along with what software is being used in government networks.

If Joe Biden defeats Donald Trump in November, the question he will face is not whether to restore the liberal international order. It is whether the United States can work with an inner core of allies to promote democracy and human rights while cooperating with a broader set of states to manage the rules-based international institutions needed to face transnational threats.

The Internet of Things (IoT) refers to the increasing convergence of the physical and digital worlds and it affects us all. Hundreds of "things" are being connected to the Internet and each other, with more than fifty billion devices expected to be connected by 2030. Many IoT devices are manufactured abroad at low cost with little consideration for security. How can we secure these devices, especially those manufactured outside the United States?

Harvard University has created a Presidential Committee on Sustainability (PCS) to advise President Larry Bacow and the University's leadership on sustainability vision, goals, strategy, and partnerships. The Harvard Gazette spoke with committee chairs Rebecca Henderson, the John and Natty McArthur University Professor; John Holdren, the Teresa and John Heinz Professor of Environmental Policy at Harvard Kennedy School; and Katie Lapp, executive vice president, about why it is so important to act now; the role of the PCS in developing collaborative and innovative projects; and how the campus community can get involved.
