One critical problem with traditional chemotherapies is that the rapid high doses – which are aimed at eradicating the tumour – can actually end up selecting for cancer cells that are resistant to the drugs. When the cancer grows back (as it often does), the drugs no longer work because all of the cells that remain are ones that grew back from the few resistant cells that survived the high-dose therapy. Ironically, the higher the chemotherapy dose, the stronger the selection pressure favouring drug-resistant cells (because the differential fitness between sensitive and resistant cells is higher with stronger treatment).

Historically, clusters have been pivotal in driving long-term US growth and for creating innovations that improve the lives of billions of people around the globe. As economists William Kerr and Frederic Robert-Nicoud summarize, there has been a continual movement of leading tech clusters over time in the US. In the 1800s, Lowell, Massachusetts was the center for textile mills relying on water power. By the early 1900s, Cleveland, Ohio was instrumental in pushing forward the frontier on electricity and steel. Detroit, Michigan, of course, developed into the powerhouse for automobile manufacturing in the mid-1900s.
Currently, US tech clusters are the envy of the world. There are only four trillion dollar companies in the world. Two of them are based near San Francisco (Apple and Alphabet), and two near Seattle (Amazon and Microsoft). Of the global top 30 Internet firms, 14 are based in SF alone.
In March, as panic over the coronavirus caused stock prices to crash and made banks and bondholders skittish about lending, the Fed acted to support the economy by flooding it with extra cash it hoped would help keep normal what could be kept normal. It cut interest rates from 1.5 percent to zero, announced it would purchase $700 billion in Treasury bonds and other assets to push down long-term interest rates, and provided liquidity to keep corporations able to borrow and banks able to lend. The Fed’s actions have saved Wall Street — the Dow Jones Industrial Average, which bottomed out at 18,214 on March 23, regained half its losses by mid-April and returned to near-record levels in early September — and have also done a great deal to reduce the pain on Main Street by keeping consumer credit available and interest rates on mortgages and credit cards low. Through its swift and sensible action, the Fed helped forestall corporate bankruptcies and prevented the job losses of the spring from being even worse. The Fed did not — and could not — fix everything that was wrong in our economy with the tools it has available. But imagine if this year had featured a new financial crisis on top of over 220,000 deaths and tens of millions of job losses, and you can see what we have the Fed to thank for.

Wickman, it turns out, pretty much invented intercity bus travel—which for most Americans equals Greyhound, the company that emerged from that long-ago Hupmobile ride. “Greyhound has become generic for bus travel,” says Robert Gabrick, author of Going The Greyhound Way. “Like Kleenex for tissues.” Indeed, this classic American business icon—which, as it happens, is now owned by a British conglomerate—today has more than 7,300 employees, with estimated yearly sales of $820 million and 2,000 buses serving 3,800 destinations in 48 U.S. states and nine Canadian provinces. “I’m amazed at Greyhound’s brand recognition,” says DePaul University professor Joseph Schwieterman, an authority on intercity bus travel. “It’s an American success story.”

Right-wing populism did not emerge in the United States because of Trump’s deranged charisma. Nor did it begin with the news media’s infatuation with his outrageous statements, or with Russian meddling, or with social media. Rather, right-wing populism resurged as a potent political force at least two decades before Trump’s takeover of the Republican Party—remember Pat Buchanan? And it has analogs all over the world, not just in mature democracies reeling from the loss of manufacturing jobs but in countries that have benefited economically from globalization, including Brazil, Hungary, India, the Philippines, Poland, and Turkey.
