A few years ago, I saw a guy in a jet suit take off in San Francisco's Golden Gate Park. The roar was deafening, the smell of fuel overwhelming. Over the span of a few minutes, he hovered above the ground and moved about a bit. The jet suit's inventor, Richard Browning, had left a career in the energy industry and a stint in the Royal Marines, to go after a childhood dream. Amazingly, he'd succee

In his account of why people, and nations, lie about their conduct in war, the political philosopher Michael Walzer observed: "Wherever we find hypocrisy, we also find moral knowledge." The hypocrite appreciates as well as anyone that there is "a way of talking about wars and battles that the rest of us appreciate as morally appropriate." As in war, so too in politics. Tomorrow marks the start of
A s the COVID-19 pandemic continues into the fall, the Trump administration has ruled out any further action on a federal relief package. Meanwhile, state and local governments, lacking federal support, are considering deep cuts to budgets and public services. These measures reflect a deep problem in American policy and culture: the systematic undermining of public infrastructure. When I refer to
A memorable campaign ad from 2008 urged voters to ask themselves which candidate would perform better in an unexpected emergency: "It's 3 a.m. and your children are safe and asleep, but there's a phone in the White House and it's ringing … Your vote will decide who answers that call." Franklin D. Roosevelt answered Pearl Harbor. John F. Kennedy answered the deployment of Soviet missiles to Cuba
Across the country, Black Americans feel under siege from the coronavirus pandemic and raw from the police brutality fueling Black Lives Matter protests.

Critiques of capitalism come in two varieties. First, there is the moral or spiritual critique. This critique rejects Homo economicus as the organising heuristic of human affairs. Human beings, it says, need more than material things to prosper. Calculating power is only a small part of what makes us who we are. Moral and spiritual relationships are first-order concerns. Material fixes such as a

Concrete is all around us: we use it to build our roads, buildings, bridges and much more. Yet over the last 2,000 years, the art of mixing cement and using it to bind concrete hasn't changed very much — and it remains one of the world's biggest emitters of carbon. Entrepreneur Tom Schuler previews an innovative way to create concrete, potentially turning it into a carbon sink that traps CO2 from
Concrete is the second most-used substance on Earth (behind water), and it's responsible for eight percent of the world's carbon footprint. Cement researcher Karen Scrivener shares the research behind a pioneering new kind of cement known as LC3, which could slash carbon emissions from this crucial building material by 40 percent, if adopted at scale.

A team of scientists at Utah State University has developed a new tool to forecast drought and water flow in the Colorado River several years in advance. Although the river's headwaters are in landlocked Wyoming and Colorado, water levels are linked to sea surface temperatures in parts of the Pacific and Atlantic oceans and the water's long-term ocean memory.
