By the time you reach for that head of lettuce at the grocery store, it's already probably traveled hundreds of miles and spent almost two weeks sitting in a truck.
"Food is no longer grown for human beings, it's grown for a truck to support a supply chain," says the president of Metropolis Farms in Philadelphia.
But everyone likes fresh produce, so the closer your veggies are grown to your favorite supermarket or restaurant, the better. With the recent outbreak of E.coli contaminating romaine lettuce across the United States, it's especially appealing to know that your produce has been grown nearby in a safe environment. How about a farm right on top of a grocery store in Philadelphia? Or one underground in the heart of Manhattan? Or one inside an iconic restaurant in Australia?
Hyper-local urban farming is providing some consumers with instant access to seriously fresh produce. It's also a way for restaurants and food suppliers to save on costs, eliminating the need for expensive packaging and shipping, experts say. Tour five of the world's coolest vertical farms in pictures below.
NEW YORK
Farm.One's vision is to build small indoor farms in cities around the country that provide rare herbs and produce to high-end restaurants. Their farm in the heart of Manhattan occupies 1200 square feet in a basement beneath the two-Michelin-starred restaurant Atera, which is conveniently one of their customers. All of the 20 to 25 restaurants they supply to are within a three-mile radius, making delivery possible by subway or bike.
"We have a direct connection with the chefs," says the CEO and founder Robert Laing. "For very perishable produce like herbs and leafy greens, hyper-local vertical farming works really well. It's literally dying the moment you cut it, and this is designed to be fresh."
PHILADELPHIA
"Restaurants are important," says Jack Griffin, the president of the indoor vertical Metropolis Farms in Philadelphia. "But not the most important, because they don't feed the majority of people."
Griffin is on a mission to standardize the indoor farming industry so supermarkets and communities around the world can benefit from the technology in a cost-effective and accessible way. Right now, Metropolis Farms supplies to a local grocer, Di Brunos Bros, that is less than two miles from their facility. In the future, they have plans to build a rooftop greenhouse atop a new supermarket in Philadelphia, plus indoor farms in Baltimore, Oklahoma, and as far away as India.
One advantage of their farms, says Griffin, is their proprietary technology. An adaptive lighting system allows them to grow almost any size crop, including tomatoes, cucumbers, peppers, strawberries, and even giant sunflowers.
"It's bigger than just food," he explains. "We are working on growing specialty crops like wine, chocolate, and coffee. All these plants are within reach, and we can cut the cord between supply chains that are difficult to deal with. Can you imagine if you grew Napa wines in Camden, New Jersey?"
BERLIN
GOOD BANK, in Berlin, bills itself as the world's first farm-to-table vertical restaurant. They grow their many of their own vegetables and salads onsite using farming system technology from another German company called INFARM. The latter's co-founder and CEO, Erez Galonska, cites a decline in traditional farming, an increase in urban populations, and the inefficiency of the current food system as motivation for turning to vertical farming to produce food where people actually eat and live.
"INFARM is pioneering on-demand farming services to help cities become self-sufficient in their food production, while eliminating waste and reducing their environmental impact," Galonska says.
MELBOURNE
Melbourne-based Farmwall leases indoor vertical farms the size of small bookshelves to restaurants and cafes. The farms are designed to be visually appealing, with fish tanks at the bottom supplying nutrient-rich water to the hemp media in which herbs and microgreens grow under LED lights. As part of the subscription model, urban farmers come once a week to check water levels, bring new trays of greens, and maintain the system. So far, two restaurants have signed up -- Top Paddock, in the suburb of Richmond, and Higher Ground, an internationally recognized restaurant in Melbourne.
"It's worth it to the restaurants because they get fresh produce at their fingertips and it has all the benefits of having a garden out back without any of the work," says Serena Lee, Farmwall's co-founder and chief communications officer.
The sky's the limit for future venue possibilities: nursing homes, schools, hotel lobbies, businesses, homes.
"Urban farming is never going to feed the world," Lee acknowledges. "We understand that and we're not saying it will, but when people are able to watch their food grow onsite, it triggers an awareness of local food production. It teaches people about how technology and science can work in coherence with nature to create something super-efficient, sustainable, and beautiful."
LOS ANGELES
At the restaurant Otium in Los Angeles, a peaceful rooftop garden sits atop a structure of concrete and steel that overlooks the hustle and bustle of downtown LA. Vegetables and herbs grown on the roof include Red Ribbon Sorrel, fennel fronds, borage blossoms, nasturtium, bush basil, mustard frills, mustard greens, kale, arugula, petit leaf lettuce, and mizuna. Chef Timothy Hollingsworth delights in Otium's ability to grow herbs that local purveyors don't offer, like the wild Middle Eastern Za'atar he uses on grilled steak with onions and sumac.
"I don't think this growing trend [of urban farming] is something that will be limited to a handful of restaurants," says Hollingsworth. "Every business should be concerned with sustainability and strive to protect the environment, so I think we will be seeing more and more gardening efforts throughout the country."
Whether a garden is vertical or horizontal, indoors or outdoors, on a roof or in a basement, tending to one provides not only fresh food, but intangible benefits as well.
"When you put your time and love into something," says Hollingsworth, "it really makes you respect and appreciate the produce from every stage of its life."

Stronger psychedelics that rewire the brain, with Doug Drysdale
A promising development in science in recent years has been the use technology to optimize something natural. One-upping nature's wisdom isn't easy. In many cases, we haven't - and maybe we can't - figure it out. But today's episode features a fascinating example: using tech to optimize psychedelic mushrooms.

These mushrooms have been used for religious, spiritual and medicinal purposes for thousands of years, but only in the past several decades have scientists brought psychedelics into the lab to enhance them and maximize their therapeutic value.
Today’s podcast guest, Doug Drysdale, is doing important work to lead this effort. Drysdale is the CEO of a company called Cybin that has figured out how to make psilocybin more potent, so it can be administered in smaller doses without side effects.
The natural form of psilocybin has been studied increasingly in the realm of mental health. Taking doses of these mushrooms appears to help people with anxiety and depression by spurring the development of connections in the brain, an example of neuroplasticity. The process basically shifts the adult brain from being fairly rigid like dried clay into a malleable substance like warm wax - the state of change that's constantly underway in the developing brains of children.
Neuroplasticity in adults seems to unlock some of our default ways of of thinking, the habitual thought patterns that’ve been associated with various mental health problems. Some promising research suggests that psilocybin causes a reset of sorts. It makes way for new, healthier thought patterns.
So what is Drysdale’s secret weapon to bring even more therapeutic value to psilocybin? It’s a process called deuteration. It focuses on the hydrogen atoms in psilocybin. These atoms are very light and don’t stick very well to carbon, which is another atom in psilocybin. As a result, our bodies can easily breaks down the bonds between the hydrogen and carbon atoms. For many people, that means psilocybin gets cleared from the body too quickly, before it can have a therapeutic benefit.
In deuteration, scientists do something simple but ingenious: they replace the hydrogen atoms with a molecule called deuterium. It’s twice as heavy as hydrogen and forms tighter bonds with the carbon. Because these pairs are so rock-steady, they slow down the rate at which psilocybin is metabolized, so it has more sustained effects on our brains.
Cybin isn’t Drysdale’s first go around at this - far from it. He has over 30 years of experience in the healthcare sector. During this time he’s raised around $4 billion of both public and private capital, and has been named Ernst and Young Entrepreneur of the Year. Before Cybin, he was the founding CEO of a pharmaceutical company called Alvogen, leading it from inception to around $500 million in revenues, across 35 countries. Drysdale has also been the head of mergers and acquisitions at Actavis Group, leading 15 corporate acquisitions across three continents.
In this episode, Drysdale walks us through the promising research of his current company, Cybin, and the different therapies he’s developing for anxiety and depression based not just on psilocybin but another psychedelic compound found in plants called DMT. He explains how they seem to have such powerful effects on the brain, as well as the potential for psychedelics to eventually support other use cases, including helping us strive toward higher levels of well-being. He goes on to discuss his views on mindfulness and lifestyle factors - such as optimal nutrition - that could help bring out hte best in psychedelics.

How the body's immune resilience affects our health and lifespan
Story by Big Think
It is a mystery why humans manifest vast differences in lifespan, health, and susceptibility to infectious diseases. However, a team of international scientists has revealed that the capacity to resist or recover from infections and inflammation (a trait they call “immune resilience”) is one of the major contributors to these differences.
Immune resilience involves controlling inflammation and preserving or rapidly restoring immune activity at any age, explained Weijing He, a study co-author. He and his colleagues discovered that people with the highest level of immune resilience were more likely to live longer, resist infection and recurrence of skin cancer, and survive COVID and sepsis.
Measuring immune resilience
The researchers measured immune resilience in two ways. The first is based on the relative quantities of two types of immune cells, CD4+ T cells and CD8+ T cells. CD4+ T cells coordinate the immune system’s response to pathogens and are often used to measure immune health (with higher levels typically suggesting a stronger immune system). However, in 2021, the researchers found that a low level of CD8+ T cells (which are responsible for killing damaged or infected cells) is also an important indicator of immune health. In fact, patients with high levels of CD4+ T cells and low levels of CD8+ T cells during SARS-CoV-2 and HIV infection were the least likely to develop severe COVID and AIDS.
Individuals with optimal levels of immune resilience were more likely to live longer.
In the same 2021 study, the researchers identified a second measure of immune resilience that involves two gene expression signatures correlated with an infected person’s risk of death. One of the signatures was linked to a higher risk of death; it includes genes related to inflammation — an essential process for jumpstarting the immune system but one that can cause considerable damage if left unbridled. The other signature was linked to a greater chance of survival; it includes genes related to keeping inflammation in check. These genes help the immune system mount a balanced immune response during infection and taper down the response after the threat is gone. The researchers found that participants who expressed the optimal combination of genes lived longer.
Immune resilience and longevity
The researchers assessed levels of immune resilience in nearly 50,000 participants of different ages and with various types of challenges to their immune systems, including acute infections, chronic diseases, and cancers. Their evaluation demonstrated that individuals with optimal levels of immune resilience were more likely to live longer, resist HIV and influenza infections, resist recurrence of skin cancer after kidney transplant, survive COVID infection, and survive sepsis.
However, a person’s immune resilience fluctuates all the time. Study participants who had optimal immune resilience before common symptomatic viral infections like a cold or the flu experienced a shift in their gene expression to poor immune resilience within 48 hours of symptom onset. As these people recovered from their infection, many gradually returned to the more favorable gene expression levels they had before. However, nearly 30% who once had optimal immune resilience did not fully regain that survival-associated profile by the end of the cold and flu season, even though they had recovered from their illness.
Intriguingly, some people who are 90+ years old still have optimal immune resilience, suggesting that these individuals’ immune systems have an exceptional capacity to control inflammation and rapidly restore proper immune balance.
This could suggest that the recovery phase varies among people and diseases. For example, young female sex workers who had many clients and did not use condoms — and thus were repeatedly exposed to sexually transmitted pathogens — had very low immune resilience. However, most of the sex workers who began reducing their exposure to sexually transmitted pathogens by using condoms and decreasing their number of sex partners experienced an improvement in immune resilience over the next 10 years.
Immune resilience and aging
The researchers found that the proportion of people with optimal immune resilience tended to be highest among the young and lowest among the elderly. The researchers suggest that, as people age, they are exposed to increasingly more health conditions (acute infections, chronic diseases, cancers, etc.) which challenge their immune systems to undergo a “respond-and-recover” cycle. During the response phase, CD8+ T cells and inflammatory gene expression increase, and during the recovery phase, they go back down.
However, over a lifetime of repeated challenges, the immune system is slower to recover, altering a person’s immune resilience. Intriguingly, some people who are 90+ years old still have optimal immune resilience, suggesting that these individuals’ immune systems have an exceptional capacity to control inflammation and rapidly restore proper immune balance despite the many respond-and-recover cycles that their immune systems have faced.
Public health ramifications could be significant. Immune cell and gene expression profile assessments are relatively simple to conduct, and being able to determine a person’s immune resilience can help identify whether someone is at greater risk for developing diseases, how they will respond to treatment, and whether, as well as to what extent, they will recover.
