Nevertheless, Horwitz, who is also a RECOVER principal investigator, believes the study will give a clearer view of the impact of long covid on Black people. Gregorio Millett, vice president and director for public policy for amfAR, the Foundation for AIDS Research, agrees. Millett, who is an epidemiologist, coauthored the first research paper to point out that Black people were contracting covid-19 disproportionately in the US. He says there are enough Black participants “to conduct several comparative analyses with other races or ethnicities.”
RECOVER is still recruiting participants. When the recruitment period ends, the project could finally start to answer some of the big questions about long covid and its impact on subgroups such as Black Americans. In this third year of the pandemic, the disease already casts a shadow on the daily lives of millions of people. Understanding the burden of long covid—both as an illness and as an economic event—is crucial if government officials or clinicians hope to foster equality in a health-care system that is already stacked against people of color.
As of early August, more than 93 million covid cases had been reported in the US—though the number of actual cases is believed to be far higher. Covid vaccinations and boosters reduce infection risk, but they offer no guarantees. (It is thought, however, that vaccines reduce the risk of developing long covid after a breakthrough infection by 15%.)
When Ostrosky treats patients recovering from covid, he finds they tend to fall into one of “three buckets.” Some are recovering from severe symptoms and organ failure; others acquired a chronic illness, such as diabetes, during their covid infection; and then there are those with long covid.
“These are the most difficult to treat,” he says of long covid patients. “They have serious symptoms, but we can’t find anything organically wrong or any underlying disease.”
Some have already struggled for many months. Fisher remembers the day her long covid symptoms started: August 11, 2020. Her handwriting changed. Her right foot started shaking. By the next morning, she was having tremors over her entire body that prevented her from walking or taking care of herself.
Doctors ultimately placed implants on her spine to deliver electrical stimulation and calm the tremors in her upper and lower extremities. She can now unlock her door and apply her own makeup. After months using a wheelchair, she can move short distances with the help of a wheeled walker and leg braces. But she still can’t work.
Fisher she says she’s fortunate to have insurance, access to quality medical care, and a doctor who advocated for her. But she also recalls the condescension and dismissiveness she felt from some medical staff. She had to make repeated ER visits before her symptoms were taken seriously. This is not uncommon for Black women, who are more likely to have negative experiences in medical settings and more likely to be permanently injured or die because of them.
China is betting big on another gas engine alternative: methanol cars
Today, the leading company making methanol from carbon dioxide is Carbon Recycling International, an Icelandic company. Geely invested in CRI in 2015, and they have partnered to build the world’s largest CO2-to-fuel factory in China. When it’s running, it could recycle 160,000 tons of CO2 emissions from steel plants every year.
The potential for clean production is what makes methanol desirable as a fuel. It’s not just a more efficient way to use energy, but also a way to remove existing CO2 from the air. To reach carbon neutrality by 2060, as China has promised, the country can’t put all its eggs in one basket, like EVs. Popularizing the use of methanol fuel and the clean production of methanol may enable China to hit its target sooner.
Can methanol move beyond its dirty roots?
But the future is not all bright and green. Currently, the majority of methanol in China is still made by burning coal. In fact, the ability to power cars with coal instead of oil, which China doesn’t have much of, was a major reason the country pursued methanol in the first place. Today, the Chinese provinces that lead in methanol-car experiments are also the ones that have abundant coal resources.
But as Bromberg says, unlike gas and diesel, at least methanol has the potential to be green. The production of methanol may still have a high carbon footprint today, just as most EVs in China are still powered by electricity generated from coal. But there is a path to transition from coal-produced methanol to renewables-produced methanol.
“If that is not an intention—if people are not going to pursue low-carbon methanol—you really don’t want to implement methanol at all,” Bromberg says.
Methanol fuel also has other potential drawbacks. It has a lower energy density than gasoline or diesel, requiring bigger, heavier fuel tanks—or drivers may need to refuel more often. This also effectively prevents methanol from being used as an airplane fuel.
What’s more, methanol is severely toxic when ingested and moderately so when inhaled or when people are exposed to it in large amounts. The potential harm was a big concern during the pilot program, though the researchers concluded that methanol proved no more toxic to participants than gas.
Beyond China, some other countries, like Germany and Denmark, are also exploring the potential of methanol fuels. China, though, is at least one step ahead of the rest—even if it remains a big question whether it will replicate its success in developing EVs or follow the path of another country with a major auto industry.
In 1982, California offered subsidies for car manufacturers to make over 900 methanol cars in a pilot program. The Reagan administration even pushed for the Alternative Motor Fuels Act to promote the use of methanol. But a lack of advocacy and the falling price of gasoline prevented further research of methanol fuel, and pilot drivers, while generally satisfied with their cars’ performance, complained about the availability of methanol fuel and the smaller range compared with gas cars. California officially ended the use of methanol cars in 2005, and there’s been no such experimentation in the US since.
Can we find ways to live beyond 100? Millionaires are betting on it.
But to test the same treatments in people, we’d need to run clinical trials for decades, which would be very difficult and extremely expensive. So the hunt is on for chemical clues in the blood or cells that might reveal how quickly a person is aging. Quite a few “aging clocks,” which purport to give a person’s biological age rather than their chronological age, have been developed. But none are reliable enough to test anti-aging drugs—yet.
As I leave to head back to my own slightly less posh but still beautiful hotel, I’m handed a gift bag. It’s loaded up with anti-aging supplements, a box with a note saying it contains an AI longevity assistant, and even a regenerative toothpaste. At first glance, I have absolutely no idea if any of them are based on solid science. They might be nothing more than placebos.
Ultimately, of all the supplements, drugs and various treatments being promoted here, the workout is the one that’s most likely to work, judging from the evidence we have so far. It’s obvious, but regular exercise is key to gaining healthy years of life. Workouts designed to strengthen our muscles seem to be particularly beneficial for keeping us healthy, especially in later life. They can even help keep our brains young.
I’ll be penning a proper write up of the conference when I’m back home, so if your curiosity has been piqued, keep an eye out for that next week! In the meantime, here’s some related reading:
- I wrote about what aging clocks can and can’t tell us about our biological age earlier this year.
- Anti-aging drugs are being tested as a way to treat covid. The idea is that, by rejuvenating the immune system, we might be able to protect vulnerable older people from severe disease.
- Longevity scientists are working to extend the lifespan of pet dogs. There’ll be benefits for the animals and their owners, but the eventual goal is to extend human lifespan, as I wrote in August.
- The Saudi royal family could become one of the most significant investors in anti-aging research, according to this piece by my colleague Antonio Regalado. The family’s Hevolution Foundation plans to spend a billion dollars a year on understanding how aging works, and how to extend healthy lifespan.
- While we’re on the subject of funding, most of the investment in the field has been poured into Altos Labs—a company focusing on ways to tackle aging by reprogramming cells to a more youthful state. The company has received financial backing from some of the wealthiest people in the world, including Jeff Bezos and Yuri Milner, Antonio explains.
From around the web
An experimental Alzheimer’s drug appears to slow cognitive decline. It’s huge news, given the decades of failed attempts to treat the disease. But the full details of the study have not yet been published, and it is difficult to know how much of an impact the drug might have on the lives of people with the disease. (STAT)
Bionic pancreases could successfully treat type 1 diabetes, according to the results of a clinical trial. The credit card-sized device, worn on the abdomen, can constantly monitor a person’s blood sugar levels, and deliver insulin when needed. (MIT Technology Review)
We’re headed for a dementia epidemic in US prisons. There’s a growing number of older inmates, and the US penal system doesn’t have the resources to look after them. (Scientific American)
Unvaccinated people are 14 times more likely to develop monkeypox disease than those who receive the Jynneos vaccine are, according to the US Centers for Disease Control and Prevention. But the organization doesn’t yet know how the vaccine affects the severity of disease in those who do become unwell, or if there is any difference in protection for people who are given fractional doses. (The New York Times $)
Don’t call them minibrains! In last week’s Checkup, I covered organoids—tiny clumps of cells meant to mimic full-grown organs. They’ve mainly been used for research, but we’ve started to implant them into animals to treat disease, and humans are next. Arguably the best-known organoids are those made from brain cells, which have been referred to as minibrains. A group of leading scientists in the field say this wrongly implies that the cells are capable of complex mental functions, like the ability to think or feel pain. They ask that we use the less-catchy but more accurate term “neural organoid” instead. (Nature)
That’s it for this week. Thanks for reading!
The Download: text-to-video AI, and China’s big methanol bet
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.
Meta’s new AI can turn text prompts into videos
What’s happened: Meta has unveiled an AI system that generates short videos based on text prompts. Make-A-Video lets you type in a string of words, like “A dog wearing a superhero outfit with a red cape flying through the sky,” and then generates a five-second clip that, while pretty accurate, has the aesthetics of a trippy old home video.
How it works: Meta combined data from three open-source image and video data sets to train its model. Standard text-image data sets of labeled still images helped the AI learn what objects are called and what they look like. And a database of videos helped it learn how those objects are supposed to move in the world.
Why it matters: Although the effect is rather crude, the system offers an early glimpse of what’s coming next for generative artificial intelligence, and it is the next obvious step from the text-to-image AI systems that have caused huge excitement this year. But it also raises some big ethical questions. Read the full story.
China is betting big on another gas engine alternative: methanol cars
As the Chinese government works to reach ambitious carbon goals, the country has become a global leader in the adoption of electric vehicles. But that’s not the only greener car alternative it’s pursuing.
While methanol fuel has been discussed and piloted in China for a decade, its adoption has long lagged. Now the government is trying to accelerate the adoption of methanol cars, along with other state efforts in the last year to draft methanol car standards and support relevant industries, reaffirm its commitment to the alternative fuel.
This matters because, just like EVs, the technology could become both a commercial success and a political boost to China’s climate-tech ambitions. Read the full story.

The big story
Meet the wannabe kidfluencers struggling for stardom
On YouTube, children can become millionaires—seemingly overnight, without trying. The highest paid of them, eight-year-old Ryan Kaji, made $22 million in 2018 by playing with toys on his channel Ryan ToysReview (now Ryan’s World). There are now thousands of similarly famous child YouTubers: babies who have been vlogged since the moment of their birth, 10-year-old streamers showing off video-game tricks, teenage girls giving acne advice from their bedrooms.
Why do so many kids want to be YouTubers? Do they only seek fame, or is there more to it: creativity, community, and a future career? How are their parents helping them? And what happens if, after spending thousands of dollars or dropping out of school, it doesn’t work out? Read the full story.
