A Rutgers biophysical chemist and his brother, a political scientist on the West Coast, have joined intellectual forces, realizing a long-standing dream of co-authoring an article that bridges their disciplines involving cells and society.

In their paper, they have proposed that powerful parallels exist between the microscopic, natural world of cells and molecules and the human-forged realm of organizations and political systems.

Taking it a step further, the brothers – eminent scholars who have served as top leaders of their respective institutions – have proposed that humankind can draw lessons from what the microscopic and macroscopic worlds have in common. Ideally, they said, their perspective could alert policymakers to strategies for responding adaptively to improve the performance of their institutions and political systems.

Writing in the Proceedings of the National Academies of Science Nexus, Kenneth Breslauer, a Linus C. Pauling Distinguished Professor of Chemistry and Chemical Biology with the Rutgers School of Arts and Sciences (SAS), and his older brother, George Breslauer, a Chancellor’s Professor of Political Science at the University of California-Berkeley, have identified and analyzed similarities in rules that apply to both the natural and social realms.

“Our focus is particularly timely given the growing global challenges to various forms of governance and the emergence of history-changing biology,” said Kenneth, who has been a member of the Rutgers faculty for 50 years and is the university’s founding dean of life sciences. “Many stability-based concepts, characteristics and phenomena within the physical sciences find analogous expression in the influences on the relative stabilities of socio-political systems.”

Kenneth, one the world’s foremost authorities on the forces that control the structure and function of biological molecules, was described in 2018 by former SAS Executive Dean Peter March as “the architect of our outstanding life science programs, which have helped establish Rutgers as a premier institution within the [Association of American Universities.]” In addition, Kenneth has been the dean of the Division of Life Sciences, the vice president for Health Science Partnerships and the vice president for Research.

His brother George is recognized as a world-renowned expert in Soviet and Russian politics and foreign relations. In his area of expertise, he is the author of 14 books. At UC Berkeley, George has been the chair of the Center for Slavic and East European Studies, dean of the social sciences, executive dean of the College of Letters and Science and executive vice chancellor and provost.

Born 14 months apart, the Breslauers grew up in Jackson Heights, Queens, raised by parents who were refugees from Nazi Germany.

“George and I are each other’s best friend,” Kenneth said.

The brothers have waited years to work together. Their paper, they said, is a “bucket list” item for both.

The two used the shared concept of “stability” as their prism.

The molecular workings of microscopic systems such as a cell or molecule are generally understood to be subject to the laws of nature, the Breslauers said, while social and political events are thought to be structured by human action and chance. However, both natural, molecular systems and sociopolitical organizations, under the influences of analogous features, they said, exhibit some level of stability, instability and even "metastability," a state of precarious stability.

For example, a chemical system can be metastable for extended periods of time, when it becomes trapped in a high energy state, until outside influences are sufficient to perturb and disrupt the stability of the trapped species. Analogously, isolated social states such as the former country of East Germany can persist in a metastable state for decades until the isolating boundaries are breached by outside influences.

The researchers likened a political science macroscopic concept, known as the “collective action” barrier, with the chemical property of cooperativity, which accelerates microscopic molecular transformations from one chemical state to another.

With respect to the societal collective action barrier, individuals who want to change an aspect of their government are less likely to act if they believe they are alone. Rather, they are more likely to advocate collectively for change if they believe they are one of many similarly minded people.

Likewise, in the natural world, when molecules are arranged in an optimal configuration, they can collectively “snowball,” accelerating a chemical transformation. This phenomenon is known as a cooperative transition.

The idea for the study arose five years ago when the Breslauer brothers were strolling near Lincoln Center in Manhattan. George mentioned that his latest work had just been published. Kenneth asked George about the theme of his research that shaped the publications.

“He told me it was proposing what features allow certain social institutions to maintain stability for extended periods of time, a characteristic that can be referred to as ‘longitudinal persistence,’” Kenneth said. “George went on to identify about five characteristics that were necessary. I stopped him at that point and said, ‘George, you just described features that are completely analogous to what provides molecules with their stability.’”

Kenneth then realized that the microscopic molecular world he studied exhibited many analogous core features with the macroscopic societal world that his brother studied, particularly in terms of the features that allow systems to form, adapt and persist, or rise and fall like the Roman Empire.

“One can think of a central government as the central nucleus of the cell,” Kenneth said. “Imagine regional governments as the embedded mitochondria and other specialized organelles. Carrying the analogy further, a country's borders are analogous to the cell membrane.”

Kenneth added; “There are so many parallels between nature and society. Identifying and examining such structural, organizational and functional analogues yields a wealth of information that is just waiting to be mined.”

 

Wristband monitors provide detailed account of air pollution exposure

COLUMBIA UNIVERSITY'S MAILMAN SCHOOL OF PUBLIC HEALTH





Environmental epidemiologists at Columbia University Mailman School of Public Health, in collaboration with an interdisciplinary team of researchers at Oregon State University, Pacific Northwest National Labs, and Mt. Sinai School of Medicine, report on the findings of a new study of air pollution exposures collected using personal wristband monitors worn by pregnant individuals in New York City matched with data from a questionnaire. Factors predictive of exposures to air pollution include income, time spent outdoors, maternal age, country of birth, transportation type, and season.

The researchers examined an unprecedented number of 61 air pollution compounds known as polycyclic aromatic hydrocarbons (PAHs) and compared them to 75 questionnaire variables, making the study the most comprehensive analysis of its kind. PAHs are created by combustion and can be found in sources like automotive exhaust and tobacco smoke; exposure to these compounds has been linked to various adverse health effects, including those related to fetal growth and neurodevelopment. The study’s findings appear online in the Journal of Exposure Science And Environmental Epidemiology(link is external and opens in a new window).

Participants, 177 of whom were included in the final analysis, wore silicone wristbands for 48 hours during the third trimester of pregnancy to measure exposure to PAHs. They completed a questionnaire during the third trimester of their pregnancy, answering questions related to demographic and employment information, as well as their potential exposure sources, such as cooking, smoking, and transportation.

Julie Herbstman, PhD, director of the Columbia Center for Children’s Environmental Health and senior author of the study, commented, “This study represents a significant advancement in our understanding of personal PAH exposure. By uncovering the variables that play a crucial role in exposure levels, we are better equipped to develop interventions aimed at reducing health risks.”

Previous studies have been restricted to a limited number of compounds or specific exposure scenarios (e.g. toll station workers or cooks).  Compared to these studies, the new study demonstrated substantially improved predictability due to the use of a larger dataset, as well as the use of a regression tree analysis, which accounted for each PAH compound as well as combined exposure to all PAHs. This approach helps researchers to identify those variables that are most important and/or predictive of exposure to a compound in the context of all other variables.

Sarah McLarnan, MPH, a PhD candidate at Columbia Mailman and the study’s first author, adds, “This study underscored the utility of silicone wristbands in evaluating PAH exposures and associated health outcomes. By combining questionnaire data with a 48-hour wristband deployment, we were able to refine measurements of exposure sources in terms of time and space, enabling more accurate source characterization.”

The study uncovered complex interactions between demographics and behaviors that shape exposure to individual compounds in different ways. Insights it gleaned require further study to understand the pathways by which various factors are linked to PAH exposures. As one example, the researchers are interested to know how maternal age and income are associated with behaviors or residential characteristics that are protective from some exposure sources but were shown to have opposite effect for some of the individual compounds.

The authors note that the wristbands are unable to detect all exposures to PAHs, particularly exposures via food. And because the wristbands were worn only for 48 hours, the exposures might not fully reflect an individual’s average exposure over the course of pregnancy.  

We all can reduce our exposure to PAHs by avoiding tobacco smoke and ensuring we have good indoor ventilation, especially when cooking; reduce our intake of smoked, grilled, and charbroiled foods; limit exposure to diesel fumes and wood smoke; use cedar shavings or blocks in place of mothballs for pest control; and wear gloves to avoid skin contact with soot or creosote-treated lumber, and wear a mask if cutting treated lumber. 

Previous research by the Columbia Center for Children’s Environmental Health has linked prenatal exposure to PAHs with numerous adverse outcomes in the child, including asthma, obesity, and developmental delays.

URBANA, Ill. — Urban agriculture has the potential to decentralize food supplies, provide environmental benefits like wildlife habitat, and mitigate environmental footprints, but researchers have identified knowledge gaps regarding both the benefits and risks of urban agriculture and the social processes of growing more food in urban areas.

In a new paper published in Nature Food, an interdisciplinary group of experts, including a researcher from the University of Illinois Urbana-Champaign, survey existing international studies on the benefits and downsides of urban agriculture and propose a framework for scaling it up. 

Study co-author Chloe Wardropper, assistant professor in the Department of Natural Resources and Environmental Sciences in the College of Agricultural, Consumer and Environmental Sciences (ACES) at U. of I., says more than two-thirds of the global population is expected to live in urban areas by 2050, and the resilience of these areas may be compromised by their heavy reliance on imported food. Increasing urban agriculture could reinforce the sustainability and resilience of urban regions in the future, but Wardropper says there are open questions about how best to scale up and what environmental, health, and equity concerns would need to be addressed. 

"We propose a framework of three interconnected phases to better understand and shape urban agriculture growth in the future," Wardropper said. "The first phase of growth would include expanding individuals’ interest in, knowledge of, and access to resources to undertake agriculture in urban regions. This phase should be followed by institutionalization, or the transformation of rules and organizational support for urban agriculture. Third, economic and market growth would increasingly support and diversify urban food."

She notes that urban agriculture is not a panacea; urban-rural connections will remain important for global food security and consumption. 

"We need to consider all the tools in the toolbox for sustainability and resilience under climate change," she said. "Urban agriculture could be particularly important for cities like Miami whose imports could be cut off unexpectedly by extreme weather."

The study, “Scale up urban agriculture to leverage transformative food systems change, advance social–ecological resilience and improve sustainability,” is published in Nature Food [DOI: 10.1038/s43016-023-00902-x].

The fallacy of the local bar: do individuals opt to travel farther than the neighborhood watering hole?


Peer-Reviewed Publication

COLUMBIA UNIVERSITY'S MAILMAN SCHOOL OF PUBLIC HEALTH





January 17, 2024--  Individuals travel beyond their residential neighborhood and area of work to bars, but tend to travel to liquor stores closer to home, according to a new study at the Columbia University Mailman School of Public Health and the Monash University School of Public Health and Preventive Medicine. The findings are published in the journal Drug and Alcohol Review

“Our study aimed to characterize individuals’ trips to alcohol outlets and describe these trip locations in the context of the mixed results we have seen from previous studies on alcohol outlet density and consumption,” said Christina A. Mehranbod, in the Department of Epidemiology, and first author. “Understanding where people travel to access alcohol outlets, like bars and liquor stores, is essential for understanding the environments to which people are exposed and ultimately influence decisions related to alcohol consumption.” 

Using 2014-2018 household travel data from the Victoria Integrated Survey of Travel and Activity from Victoria, Australia, the researchers categorized trip origins and destinations by 10 place types, by total trip distance and duration, and geographic location as well as transport mode, and other personal and household level variables including age, and income, among others. 

People were willing to travel to a bar travel farther than the distance and time people were willing to travel to liquor stores. Among 23,512 respondents, 378 or 1.6 percent traveled 18 minutes and approximately 5 miles to visit a bar versus the 79 study participants or 0.3 percent for a liquor store purchase. Bar trips added slightly over 5 miles and 18 minutes to cumulative travel; 41percent attended bars co-located in participants’ home local government area.

“Trips to and from liquor stores were shorter and quicker than trips to and from bars,” observed Christopher Morrison, PhD, assistant professor of Epidemiology at Columbia Mailman School, and senior author.

One-one-way trips to liquor stores had a mean distance of 8.7 miles and took 12.2 minutes, but these trips added only 3 miles and 8.9 minutes to the cumulative travel distance over the full day. “We attribute this variation because trips to liquor stores are commonly part of complex trips involving multiple stops, Morrison noted. Additionally, trips to liquor stores are part of more complex daily journeys — for example, it can be a stop between someone’s workplace and home. Also people might travel farther for unique bar experiences but proximity influences liquor store purchases.”

“This finding highlights the fact that alcohol outlet placement potentially affects populations well beyond the neighborhood in which outlets are placed,” said Morrison.

In addition to describing where people travel to access bars and liquor stores, the research team also tested the impact of alcohol outlet density on trips to alcohol outlets. In sync with other literature, Morrison and team found alcohol outlet density to play a role.

“With alcohol consumption continuing to take a considerable toll on public health, we believe that refining the scientific methods for measuring exposure to alcohol outlets that may influence decisions to consume alcohol remains a research priority,” said Mehranbod.

From dawn of time to dusk – our evolutionary ability to perceive time in art



Peer-Reviewed Publication

NEWCASTLE UNIVERSITY





Scientists have shown that people are able to tell apart morning from evening depictions in paintings using simple and subtle colour clues in the image.

A study by Newcastle University, UK, and Delft University of Technology, Netherlands, published in the Journal of Vision, has found that people use a combination of colour and brightness in a painting to predict the time of day in the image.

For a large range of paintings over three centuries, study participants were able to establish the timing regardless of the exact content or style of painting and this was purely based on the selection of shades used.

Visual perception

In an online behavioural experiment, 51 people rated 104 mostly little-known landscape paintings as depicting either morning, noon, afternoon, evening, or night.

Although the paintings were taken from a range of artists and from across the 17th to 20th century, the time of day ratings people gave them were surprisingly consistent.

In general, paintings with lighter, paler blues and darker yellows were viewed as morning, and those with darker blues and brighter yellows seen as evening.

Anya Hurlbert, Professor of Visual Neuroscience at Newcastle University, who led the study, said: “Our findings show painters tap into fundamental processes of visual perception that adults possess.

“They appear to be subconsciously understanding how the human brain has learned over evolution to interpret changes in daylight and this adds to our understanding of visual perception.

“This research is one of the first to show that painters deploy simple colour and brightness cues to convey something as abstract as time of day.”

From nature to art

The colour and brightness of natural daylight change regularly over the course of the day and offer subtle colour clues that this research showed most people interpreted in the same way.

Experts have shown that daylight is a mixture of direct sunlight and diffuse skylight, meaning the nuances in hue are constrained to follow a curve from blue to orange/yellow.  

At dawn, the light changes colour rapidly from a dark blue to a brighter yellow or neutral hue; at dusk, it changes in the opposite direction, becoming bluer as it darkens.  In morning and evening, when the sun is close to the horizon, daylight is dimmer than at midday. People were able to pick up on these subtle clues.

Professor Hurlbert said: “The experiment was performed online. A separate experiment in the lab, with a calibrated image display and a smaller number of participants, confirmed the results of the online one.

“Therefore, paintings make a rich source of information for scientists to understand how visual perception works.”

Knowing what dogs like to watch could help veterinarians assess their vision


Researchers at the University of Wisconsin–Madison have taken a novel approach to assessing canine vision. Their recent study uses a dog's interest in a variety of video content to better measure the quality of its vision.

Ever wonder what kind of TV shows your dog might choose if they could work the remote control? New research from the University of Wisconsin–Madison’s School of Veterinary Medicine provides some answers, but the study was more interested in solving a longstanding problem in veterinary medicine than turning canine companions into couch potatoes.

According to Freya Mowat, veterinary ophthalmologist and professor in the School of Veterinary Medicine’s department of surgical sciences, researchers wanted to determine factors, including age and vision, that influence a dog’s interest in interacting with video content. Ultimately, the goal of the study, which launched two years ago, was to support development of more sensitive ways to assess canine vision — something that has been sorely lacking in veterinary medicine.

“The method we currently use to assess vision in dogs is a very low bar. In humans, it would be equivalent to saying yes or no if a person was blind,” says Mowat. “We need more sensitive ways to assess vision in dogs, using a dog eye chart equivalent. We speculate that videos have the potential for sustaining a dog’s attention long enough to assess visual function, but we didn’t know what type of content is most engaging and appealing to dogs.”

Published recently in the journal Applied Animal Behaviour Sciencethe study found that dogs are most engaged when watching videos that feature other animals. Content featuring other dogs was the most popular. But if a National Geographic documentary about canine evolution seems too highbrow for your four-legged friend, Scooby Doo might be a perfectly acceptable option as well.

To better understand the type of content dogs might be most attracted to on screen, Mowat created a web-based questionnaire for dog owners around the globe to report the TV-watching habits of their canine companions.

Participants responded to questions about the types of screens in their homes, how their dogs interacted with screens, the kinds of content their dogs interacted with the most, as well as information about their dog’s age, sex, breed and where they live. They also provided descriptions of their dogs’ behavior when watching videos. Most commonly, dog owners described their pets’ behavior as active — including running, jumping, tracking action on screen and vocalizing — compared with passive behaviors like lying down or sitting. Dog owners also had the option to show their dog(s) four short videos featuring subjects of possible interest, including a panther, a dog, a bird and traffic moving along a road. They were then asked to rate their dog’s interest in each video and how closely the dog tracked the moving objects on the screen.

Mowat received 1,600 responses from dog owners across the world, including from the United States, Canada, the United Kingdom, the European Union and Australasia. Of those respondents, 1,246 ultimately completed the study. The following are some of the most interesting highlights:

  • Age and vision were related to how much a dog interacted with a screen.
  • Sporting and herding dog breeds appear to watch all content more than other breeds.
  • Video content featuring animals was the most popular, with other dogs being by far the most engaging subjects to watch.
  • Humans do not appear to be very appealing for dogs to watch, ranking ninth out of 17 predetermined categories.
  • Cartoons were engaging for more than 10% of dogs.
  • Movement on screens was a strong motivator for screen attention.

Mowat says she plans to build on the results of this study. Future research will focus on the development and optimization of video-based methods that can assess changes in visual attention as dogs age as well as answer questions that could help our four-legged friends age as gracefully as possible.

“We know that poor vision negatively impacts quality of life in older people, but the effect of aging and vision changes in dogs is largely unknown because we can’t accurately assess it,” she says. “Like people, dogs are living longer, and we want to make sure we support a healthier life for them as well.”

Another goal for Mowat is to compare how a dogs’ vision ages compared with the human or humans they share a home with.

“Dogs have a much shorter lifespan than their owner, of course, and if there are emerging environmental or lifestyle factors that influence visual aging, it might well show up in our dogs decades before it shows up in us,” she explains. “Our dogs could be our sentinels — the canine in the proverbial coal mine.”

This study was supported in part by an NIH career development grant to Mowat (K08EY028628), a Companion Animal Fund Grant from the UW–Madison School of Veterinary Medicine, a grant from Research to Prevent Blindness, Inc. to the UW–Madison Department of Ophthalmology and Visual Sciences and a core grant for Vision Research from the NIH to UW–Madison (P30 EY016665).
