Meet Altos Labs, Silicon Valley’s latest wild bet on living forever


Sometime during 2021, however, a new plan emerged to make the research move even faster by turning the idea into a well-funded company that is now Altos. That effort took shape under the direction of Richard Klausner, the one-time chief of the National Cancer Institute and now an entrepreneur. Klausner, who previously helped start companies like Juno Therapeutics and cancer-test company Grail, is known for organizing large, and lucrative, financial bets on new biotechnologies.

According to an incorporation filing in the UK for Altos Labs, Klausner is CEO of the new company. Klausner did not respond to attempts to contact him by email and phone. Like Milner, he also lives in Los Altos Hills.

A number of startups are pursuing reprogramming technology, including Life Biosciences, Turn Biotechnologies, AgeX Therapeutics, and Shift Bioscience in the UK, although these efforts have not yet led to any treatments tested on people in clinical trials.

“There are hundreds of millions of dollars being raised by investors to invest in reprogramming, specifically aimed at rejuvenating parts or all of the human body,” says David Sinclair, a researcher at Harvard University who last December reported restoring sight to mice using the technique.

Sinclair describes the field as “nascent” but thinks it has unique promise. “What else can you do that can reverse the age of the body?” he says. “In my lab we are ticking off the major organs and tissues, for instance skin, muscle and brain —to see which we can rejuvenate.” Sinclair says he is not involved in Altos but he did speak at the 2020 meeting and applied for an award from Milky Way.

A science business

Altos hasn’t made an official announcement yet, but it was incorporated in Delaware this year and a securities disclosure filed in California in June indicates the company has raised at least $270 million, according to Will Gornall, a business school professor at the University of British Columbia who reviewed the document. In addition to Bezos and Milner, the company may have additional wealthy tech figures and venture capitalists as investors.

Other hires made by Altos include Peter Walter, whose laboratory at the University of California, San Francisco, is behind a molecule that shows remarkable effects on memory. Also joining is Wolf Reik, a reprogramming specialist who recently resigned as the director of the Babraham Institute in the UK after the center said he was taking a job “with another research organization” now believed to be Altos. Walter and Reik declined to comment.

At least initially, Altos will be funding researchers with no immediate expectation for products or revenues. According to one person briefed by Klausner and Milner, the initial output of the company will be “great science.”

Altos is luring university professors by offering sports-star salaries of $1 million a year or more, plus equity, as well as freedom from the hassle of applying for grants. One researcher who confirmed accepting a job offer from Altos, Manuel Serrano of the Institute for Research in Biomedicine, in Barcelona, Spain, said the company would pay him five to 10 times what he earns now.

“The philosophy of Altos Labs is to do curiosity-driven research. This is what I know how to do and love to do,” says Serrano, who plans to move to Cambridge, UK to join an Altos facility there. “In this case, through a private company, we have the freedom to be bold and explore. In this way it will rejuvenate me.”

Any treatment for a major disease of aging could be worth billions, but Altos isn’t counting on making money at first. “The aim is to understand rejuvenation,” says Serrano. “I would say the idea of having revenue in the future is there, but it’s not the immediate goal.”

The hunter-gatherer groups at the heart of a microbiome gold rush

The hunter-gatherer groups at the heart of a microbiome gold rush


The first step to finding out is to catalogue what microbes we might have lost. To get as close to ancient microbiomes as possible, microbiologists have begun studying multiple Indigenous groups. Two have received the most attention: the Yanomami of the Amazon rainforest and the Hadza, in northern Tanzania. 

Researchers have made some startling discoveries already. A study by Sonnenburg and his colleagues, published in July, found that the gut microbiomes of the Hadza appear to include bugs that aren’t seen elsewhere—around 20% of the microbe genomes identified had not been recorded in a global catalogue of over 200,000 such genomes. The researchers found 8.4 million protein families in the guts of the 167 Hadza people they studied. Over half of them had not previously been identified in the human gut.

Plenty of other studies published in the last decade or so have helped build a picture of how the diets and lifestyles of hunter-gatherer societies influence the microbiome, and scientists have speculated on what this means for those living in more industrialized societies. But these revelations have come at a price.

A changing way of life

The Hadza people hunt wild animals and forage for fruit and honey. “We still live the ancient way of life, with arrows and old knives,” says Mangola, who works with the Olanakwe Community Fund to support education and economic projects for the Hadza. Hunters seek out food in the bush, which might include baboons, vervet monkeys, guinea fowl, kudu, porcupines, or dik-dik. Gatherers collect fruits, vegetables, and honey.

Mangola, who has met with multiple scientists over the years and participated in many research projects, has witnessed firsthand the impact of such research on his community. Much of it has been positive. But not all researchers act thoughtfully and ethically, he says, and some have exploited or harmed the community.

One enduring problem, says Mangola, is that scientists have tended to come and study the Hadza without properly explaining their research or their results. They arrive from Europe or the US, accompanied by guides, and collect feces, blood, hair, and other biological samples. Often, the people giving up these samples don’t know what they will be used for, says Mangola. Scientists get their results and publish them without returning to share them. “You tell the world [what you’ve discovered]—why can’t you come back to Tanzania to tell the Hadza?” asks Mangola. “It would bring meaning and excitement to the community,” he says.

Some scientists have talked about the Hadza as if they were living fossils, says Alyssa Crittenden, a nutritional anthropologist and biologist at the University of Nevada in Las Vegas, who has been studying and working with the Hadza for the last two decades.

The Hadza have been described as being “locked in time,” she adds, but characterizations like that don’t reflect reality. She has made many trips to Tanzania and seen for herself how life has changed. Tourists flock to the region. Roads have been built. Charities have helped the Hadza secure land rights. Mangola went abroad for his education: he has a law degree and a master’s from the Indigenous Peoples Law and Policy program at the University of Arizona.

The Download: a microbiome gold rush, and Eric Schmidt’s election misinformation plan


Over the last couple of decades, scientists have come to realize just how important the microbes that crawl all over us are to our health. But some believe our microbiomes are in crisis—casualties of an increasingly sanitized way of life. Disturbances in the collections of microbes we host have been associated with a whole host of diseases, ranging from arthritis to Alzheimer’s.

Some might not be completely gone, though. Scientists believe many might still be hiding inside the intestines of people who don’t live in the polluted, processed environment that most of the rest of us share. They’ve been studying the feces of people like the Yanomami, an Indigenous group in the Amazon, who appear to still have some of the microbes that other people have lost. 

But there is a major catch: we don’t know whether those in hunter-gatherer societies really do have “healthier” microbiomes—and if they do, whether the benefits could be shared with others. At the same time, members of the communities being studied are concerned about the risk of what’s called biopiracy—taking natural resources from poorer countries for the benefit of wealthier ones.

Navigating a shifting customer-engagement landscape with generative AI

Navigating a shifting customer-engagement landscape with generative AI


A strategic imperative

Generative AI’s ability to harness customer data in a highly sophisticated manner means enterprises are accelerating plans to invest in and leverage the technology’s capabilities. In a study titled “The Future of Enterprise Data & AI,” Corinium Intelligence and WNS Triange surveyed 100 global C-suite leaders and decision-makers specializing in AI, analytics, and data. Seventy-six percent of the respondents said that their organizations are already using or planning to use generative AI.

According to McKinsey, while generative AI will affect most business functions, “four of them will likely account for 75% of the total annual value it can deliver.” Among these are marketing and sales and customer operations. Yet, despite the technology’s benefits, many leaders are unsure about the right approach to take and mindful of the risks associated with large investments.

Mapping out a generative AI pathway

One of the first challenges organizations need to overcome is senior leadership alignment. “You need the necessary strategy; you need the ability to have the necessary buy-in of people,” says Ayer. “You need to make sure that you’ve got the right use case and business case for each one of them.” In other words, a clearly defined roadmap and precise business objectives are as crucial as understanding whether a process is amenable to the use of generative AI.

The implementation of a generative AI strategy can take time. According to Ayer, business leaders should maintain a realistic perspective on the duration required for formulating a strategy, conduct necessary training across various teams and functions, and identify the areas of value addition. And for any generative AI deployment to work seamlessly, the right data ecosystems must be in place.

Ayer cites WNS Triange’s collaboration with an insurer to create a claims process by leveraging generative AI. Thanks to the new technology, the insurer can immediately assess the severity of a vehicle’s damage from an accident and make a claims recommendation based on the unstructured data provided by the client. “Because this can be immediately assessed by a surveyor and they can reach a recommendation quickly, this instantly improves the insurer’s ability to satisfy their policyholders and reduce the claims processing time,” Ayer explains.

All that, however, would not be possible without data on past claims history, repair costs, transaction data, and other necessary data sets to extract clear value from generative AI analysis. “Be very clear about data sufficiency. Don’t jump into a program where eventually you realize you don’t have the necessary data,” Ayer says.

The benefits of third-party experience

Enterprises are increasingly aware that they must embrace generative AI, but knowing where to begin is another thing. “You start off wanting to make sure you don’t repeat mistakes other people have made,” says Ayer. An external provider can help organizations avoid those mistakes and leverage best practices and frameworks for testing and defining explainability and benchmarks for return on investment (ROI).

Using pre-built solutions by external partners can expedite time to market and increase a generative AI program’s value. These solutions can harness pre-built industry-specific generative AI platforms to accelerate deployment. “Generative AI programs can be extremely complicated,” Ayer points out. “There are a lot of infrastructure requirements, touch points with customers, and internal regulations. Organizations will also have to consider using pre-built solutions to accelerate speed to value. Third-party service providers bring the expertise of having an integrated approach to all these elements.”
