A Healthcare and Public Health Shakeup Is on Democrats’ Agenda

From my cover story in the March 12, 2021, edition of Newsweek

America has a long, sorry record of neglect, poor organization, underfunding, and misplaced priorities when it comes to public health. Add to those woes the sky-high cost of health care, uneven access and relatively poor outcomes, and it’s clear the American public has been living for decades with a health system that is failing. Can Joe Biden get American health back on track?….Read more

The virus is changing. It has already mutated into versions that spread more quickly, may kill more efficiently and threaten to undermine the effectiveness of vaccines. The nightmare scenario: the virus mutates into a variant that renders current vaccines weakened or obsolete before the rollout reaches the 150 million or so people needed to achieve herd immunity, which would halt the virus in its tracks….Read more

Under Facebook’s leadership, VR could change our lives. Will it also turn us into ‘data cattle’?

From my article in Newsweek, posted Dec. 23, 2020

If Facebook succeeds in its quest to bring VR to social-media masses, it could bring a level of realism and ease-of-use to remote interactions that makes Zoom video look like stone tablets by comparison. It would also position itself to determine not just how we swap posts online, but much of what we experience in an increasingly simulated world—in work, play, education, family, health, commerce and even love….Read more

The pandemic turbo-charged e-commerce — now the two giants are battling over the future of shipping

From my article in Marker, posted Dec. 1, 2020

Seven years ago, frustrated with FedEx and UPS delivery delays during the 2013 holiday rush, Amazon began building out its own delivery network for the products it sells and ships. Now Amazon is greasing its delivery network to deliver a much bigger blow: Going into business as a third-party shipper looking to steal business from FedEx and other shippers. But long known as the highest-tech shipper, FedEx is preparing for an all-out battle for shipping dominance, hoping it can get ahead of the one company that has managed to upend virtually every industry it’s touched….Read more

A cadre of scientists are at the forefront of efforts to map QAnon and understand how it works.

From my cover story in the Oct. 23, 2020, issue of Newsweek

The explosion of disinformation that has upended American life and now threatens its democratic institutions has given rise to a new branch of science called “infodemiology.” Inspired by epidemiology, the study of how diseases spread through a population, infodemiology seeks to understand how misinformation and conspiracy theories spread like a disease through a free-wheeling democracy like America’s, with the ultimate goal of understanding how to stem its spread….Read more

Inside Butterball’s fight to save the holiday — and its business

From my article in Marker, posted Oct. 14, 2020

Rebecca Welch remembers all too well the Thanksgiving Day she pulled the turkey out of the refrigerator to prep it for the oven and, with a crowd of in-laws standing around watching, realized it was still frozen solid. “I tried to remember everything I knew about thawing, but I was panicking,” she says. Finally, Welch did what some 100,000 other people do every year around Thanksgiving: She called Butterball’s Turkey Talk Line for help. The person at the other end talked her through the warm-water fast-thaw hack, and Thanksgiving was saved….Read more

As the weather gets colder and people spend more time inside, improving air circulation and filters in buildings will be key to controlling covid-19.

From my article in MIT Technology Review, posted Oct. 8, 2020

As we head into the Northern Hemisphere fall with covid-19 still raging in the US and a number of other parts of the world, two data points provide cause for extra concern.

One is that the seasonal flu—a respiratory viral infection like covid-19—is much more active in the winter. Last year in the US, there were 40 times as many flu cases in the fall and winter months as in the previous spring and summer. Historically, those cooler months see tens of times as many seasonal flu infections in temperate regions.

The other is that the death toll from the 1918 influenza outbreak—the only pandemic to have killed more Americans than this one so far, and one of the deadliest in global history—was five times as high in the US during the late fall and winter as during the summer….Read more

Having solved a central mystery about the “twirliness” of tornadoes and other types of vortices, William Irvine has set his sights on turbulence, the white whale of classical physics.

From my article in Quanta Magazine, posted September 3, 2020

It’s time to feed the blob. Seething and voracious, it absorbs eight dinner-plate-size helpings every few seconds.

Irvine tightly controls the loops that are the blob’s building blocks and studies the resulting confined turbulence up close and at length. The blob could yield insights into turbulence that physicists have been chasing for two centuries — in a quest that led Richard Feynman to call turbulence the most important unsolved problem in classical physics….Read more

N95 masks are life savers, and could help control the pandemic. Why can’t 3M—or anyone else—make nearly enough of them?

From my article in Marker, posted Aug. 19, 2020

On the evening of April 2, some two weeks into America’s full-blown Covid crisis, President Donald Trump fired off a tweet to his more than 80 million followers:

We hit 3M hard today after seeing what they were doing with their masks… Big surprise to many in government as to what they were doing — will have a big price to pay!

The notion of 3M ending up square in the bilious crosshairs of the Tweeter-in-Chief would have seemed absurd just days earlier. A staid, 118-year-old, Midwestern manufacturing company, 3M is best known for Scotch tape, sandpaper, and Post-It notes — it sells enough of them that it pulled in $32 billion last year, and employs nearly 100,000. Unlike the flashy high-tech wizardry radiating from Silicon Valley, 3M was built on made-America-great, meat-and-potatoes innovation. The company owns some 120,000 patents, and sells some 55,000 products. So how did a much-admired all-American sticky-paper company end up being publicly cast as a pandemic villain?….Read more

From my cover story in the August 14, 2020, edition of Newsweek

….Even in the best of times, a president who threatens to disrespect election norms and laws would be cause for alarm. These are not the best of times. The number of things likely to go wrong in this election is unprecedented. Polls are vulnerable to hacking from China, Russia and North Korea. Efforts to block voter registration and other forms of suppression are rampant, particularly in Republican-controlled states. Skyrocketing COVID-19 infections are likely to keep people from the polls. In states including California, Texas and Washington, protesters have flooded the streets for weeks; in Portland, Oregon, they have clashed with federal troops, all of which could disrupt polling. The electoral college is uniquely positioned this year to collapse, leaving the election deadlocked and plunging the nation into a constitutional crisis. Taken together, these factors make it more likely than at any other time in more than a century that a U.S. election will fail to produce a winner who is accepted by a large majority as legitimate….Read more

The Canadian e-commerce company is breathing down Silicon Valley’s neck as the next great enterprise behemoth

From my article in Marker, posted July 22, 2020

In late March, 15,000 gallons of beer were sloshing around in Peter Bulut’s tanks and barrels with nowhere to go. Bulut, the owner of Great Lakes Brewing Co., first started working in his father’s tiny craft brewery in Toronto almost 30 years ago, when he was 21. Back on March 13, when Covid-19 was creeping its way into Toronto, Bulut started taking small precautions, like suspending in-store beer tastings.  Five days after that, facing a 50% drop in business, he laid off a quarter of his 52 employees. Then Bulut had an employee call Shopify to find out what it would take to convert the company’s online merch shop into an online beer-sales-and-delivery store. Bulut was surprised by Shopify’s response. “They jumped all over it,” he says. “They wanted to help us hit big sales volumes”….Read more

Walter Hugentobler, a Swiss physician who sometimes practices at a clinic in Zurich International Airport, noticed several years ago that pilots and flight attendants seemed unusually susceptible to the flu throughout the year, even though they were generally healthy. More recently, Hazhir Rahmandad, an engineer at the Massachusetts Institute of Technology’s Sloan School of Management, noticed that COVID-19 tended to spread in his native Iran at different rates from one region to the next, even when population densities were similar.

Those two observations each led to recent studies that have converged on an important insight into COVID-19: the spread of the disease is likely to vary significantly with temperature and humidity….Read more

A longtime U.S. National Institutes of Health (NIH) researcher who now runs an institute at Germany’s University of Bonn, Andreas Zimmer has been on a long journey to answer a question that few researchers had thought to ask: Is it possible that weed, long seen as the stuff of slackers, might actually contain the secret to sharpening the aging brain? His findings have suggested that may be the case, and research in the U.S. at Harvard, Johns Hopkins and elsewhere hints the results seem to hold for humans. As the data continues to stream in, some in the Zimmer lab have begun quietly encouraging their aging parents to toke away….Read more

Can Tesla and Rivian convince practical Ford-loving pickup drivers to buy their futuristic machismo machines?

From my article in Marker, posted February 5, 2020

America’s coasts may well harbor pockets of tech-friendly, eco-conscious early adopters eager to jump to a Cybertruck, or some other whizzy, cool urban-warrior or off-road vehicle that happens to have a bed for hauling Whole Foods groceries and Patagonia gear. But Tesla and other electric truck startups won’t get far hitching their future to those sort of sub-sub-markets. They’ll need to figure out how to sell electric pickups in Houston and other places where trucks are king….Read more

The next gold rush in legalizing cannabis is public consumption. Entrepreneur J.J. Walker is already one step ahead.

Several states and cities are already cautiously opening the door to the so-called social consumption of marijuana. These new laws would permit any adult who purchases cannabis in a specially licensed business to also consume the products right there. In other words, a legal future in which enjoying weed is as simple as walking into a bar or restaurant and enjoying a glass of chardonnay. Currently there are no credible projections of the size of the social-consumption market, but there’s enough relevant math to suggest it will likely be massive….Read more

“I found this article to be a refreshing departure from most writing about health care. Of course culture matters. As a medical anthropologist, however, I thought David H. Freedman missed a key factor in health outcomes. Many people who have the worst compliance rates and outcomes (Freedman lists smokers, diabetics, and people with sedentary lifestyles as examples) also have the same socioeconomic status.

Some 1.5 million Americans have been diagnosed with lupus erythematosus. And lupus is just one of more than 100 autoimmune diseases affecting nearly 25 million Americans, diseases that together present a challenging and often frustrating path to diagnosis for doctors and patients alike. “These patients often get sent on a long journey before they get an answer,” says Robert Lahita, M.D., the chairman of medicine at St. Joseph’s Healthcare in Wayne, N.J. “Some physicians will tell them it’s all in their head. It’s not, and they can be miserable for years until they get diagnosed.” Read more

Hacking the sensory-health connection can improve well-being in surprising ways

From my article in Elemental posted September 5, 2019

About a quarter of the human brain’s mass is devoted to processing information from the five senses. Given that the brain plays such a central role in health, it’s not surprising that the five senses are closely tied to well-being.

But beyond merely proving those connections exist, researchers have recently started to explore ways to purposely manipulate them for people’s benefit. “Interventions based on what we see, feel, and even taste can have a seemingly dramatic effect on health,“ says Charles Spence, an Oxford University PhD researcher who runs a lab dedicated to studying the role that perception plays in behavior and health. “They can reduce pain, speed recovery from illness, and much more.” Read more

Pop culture says CBD cures everything—here’s what scientists say

From my cover story in the September 6, 2019, Newsweek

Hardly anyone had heard of CBD three years ago, but now two-thirds of Americans are familiar with it, according to a recent Gallup survey. One in seven Americans use it as an over-the-counter treatment for pain, anxiety and sleep problems. They have also turned to CBD for depression, muscle spasms, digestive issues and skin ailments. One in three pet owners give it to their dogs and cats, says a survey by market-research firm Packaged Facts. It’s also been touted as a treatment for cancer, Alzheimer’s disease and Parkinson’s disease. One medical clinic reported that CBD relieved 90 percent of all symptoms in all its patients.

Trouble is, almost all of the claims are currently unsubstantiated. “Consumers are participating in one of the largest uncontrolled clinical trials in history, and no one really knows what it is they’re taking,” says Pal Pacher, an investigator at the National Institutes of Health and president of the International Cannabinoid Research Society. “It’s scary”….Read more

For tens of thousands of patients, precision medicine is rewriting their cancer stories. But only a fraction of patients benefit. Can medicine close the gap?

Linda Boyed, an energetic 52-year-old occupational therapist, was thrilled to be on vacation with her family in Hawaii, hitting the beaches and taking long walks. But she couldn’t shake a constant feeling of fatigue. When she returned home, her doctor delivered the bad news: Cancer of the bile ducts in her liver had already spread too far for chemotherapy or surgery to do any good. He offered to help keep her comfortable for her final few months.

But then Boyed’s husband found a doctor at Ohio State’s cancer center who was running studies of experimental drugs for gastrointestinal cancers. That doctor gave her an experimental drug called BGJ398. Boyed’s symptoms cleared up, the tumors stopped growing, and she regained the weight she had lost….Read more
