PROVIDENCE, R.I. [Brown University] — A team of researchers from Brown University's School of Public Health, Brown’s School of Engineering and Silent Spring Institute found that simple air filtration devices called Corsi-Rosenthal boxes are effective at reducing indoor air pollutants.

The study, which analyzed the effectiveness of Corsi-Rosenthal boxes installed at the School of Public Health to help prevent the spread of COVID-19, is the first peer-reviewed study of the efficacy of the boxes on indoor pollutants, according to the authors.

Lowering indoor air concentrations of commonly-found chemicals known to pose a risk to human health is a way to improve occupant health, according to lead author Joseph Braun, an associate professor of epidemiology at Brown.

“The findings show that an inexpensive, easy-to-construct air filter can protect against illness caused not only by viruses but also by chemical pollutants,” Braun said. “This type of highly-accessible public health intervention can empower community groups to take steps to improve their air quality and therefore, their health.”

Corsi-Rosenthal boxes, or cubes, can be constructed from materials found at hardware stores: four MERV-13 filters, duct tape, a 20-inch box fan and a cardboard box. As part of a school-wide project, boxes were assembled by students and campus community members and installed in the School of Public Health as well as other buildings on the Brown University campus.

To assess the cubes’ efficacy at removing chemicals from the air, Braun and his team compared a room’s concentrations of semi-volatile organic compounds before and during the box’s operation.

The results, published in Environmental Science & Technology, showed that Corsi-Rosenthal boxes significantly decreased the concentrations of several PFAS and phthalates in 17 rooms at the School of Public Health during the period they were used (February to March 2022). PFAS, a type of synthetic chemical found in a range of products including cleaners, textiles and wire insulation, decreased by 40% to 60%; phthalates, commonly found in building materials and personal care products, were reduced by 30% to 60%.

PFAS and phthalates have been linked to various health problems, including asthma, reduced vaccine response, decreased birth weight, altered brain development in children, altered metabolism and some cancers, said Braun, who studies the effect of these chemicals on human health. They are also considered to be endocrine-disrupting chemicals that may mimic or interfere with the body’s hormones. What’s more, PFAS have been associated with reduced vaccine response in children and also may increase the severity of and susceptibility to COVID-19 in adults.

“The reduction of PFAS and phthalate levels is a wonderful co-benefit to the Corsi-Rosenthal boxes,” said study co-author Robin Dodson, a research scientist at Silent Spring Institute and expert in chemical exposures in the indoor environment.. “These boxes are accessible, easy to make and relatively inexpensive, and they’re currently being used in universities and homes across the country.”

“The Corsi-Rosenthal box was designed to be a simple, cost-effective tool to promote accessible and effective air cleaning during the COVID-19 pandemic; the fact that the boxes are also effective at filtering out air pollutants is a fantastic discovery,” said Richard Corsi, one of the inventors of the boxes and dean of the College of Engineering at the University of California, Davis. “I am thrilled that researchers at Brown University and Silent Spring Institute have identified a significant co-benefit of the boxes with respect to reduced exposure to two harmful classes of indoor pollutants: PFAS and phthalates.

The sentiment was echoed by Jim Rosenthal, Corsi’s collaborator and CEO of Air Relief Technologies, the company that manufactures the MERV-13 filters used in Corsi-Rosenthal Boxes.

“This interesting research showing that the air filters not only reduce particles carrying the SARS-CoV-2 virus but also reduce other indoor air pollutants could be very significant as we continue to work to create cleaner and safer indoor air," Rosenthal said.

The researchers also found that the Corsi-Rosenthal boxes increase sound levels by an average of 5 decibels during the day and 10 decibels at night, which could be considered distracting in certain settings, such as classrooms. However, Braun said, the health benefits of the box likely outweigh the audio side effects.

“The box filters do make some noise,” Braun said. “But you can construct them quickly for about $100 per unit, with materials from the hardware store. They are not only highly effective but also scalable.”

Brown study authors include Kate Manz and Kurt Pennell from the School of Engineering, and Jamie Liu, Shaunessey Burks and Richa Gairola from the School of Public Health. This research was supported by the National Science Foundation and the National Institute of Environmental Health Sciences.

Health of Southern California’s farmworkers needs to be a priority, says UC Riverside study

UNIVERSITY OF CALIFORNIA - RIVERSIDE

RIVERSIDE, Calif. -- A University of California, Riverside, study performed in the Eastern Coachella Valley, one of California’s top agricultural production regions, has found that farmworkers there lack information and the means to advocate for improved public health even when they are aware of being exposed to health risks stemming from working and living in rural farmlands.

About 76% of the 2.4 million farmworkers in the United States are immigrants, most of whom are from Mexico. In Inland Southern California, where the Eastern Coachella Valley, or EVC, is located, not much research has been done on Latinx farmworkers’ health concerns and barriers to care.

“Agricultural production demands in the U.S. impose a heavy burden on Latinx immigrant farmworkers, which shapes their health and informs their decisions about their living conditions,” said Ann Cheney, an associate professor of social medicine, population, and public health in the School of Medicine and lead author of the study that appears in the International Journal of Environmental Research and Public Health. “The health of these workers and their families should be a national priority.”

Cheney and her team used a community-based participatory research approach. They conducted nine in-home meetings in 2017-2018, with the help of “promotoras,” Spanish-speaking community health workers, to gather information on the health concerns of rural residents of the EVC as well as the barriers they face in accessing healthcare services. The majority of the 82 participants in the study were Mexican immigrants, women, and low-income. Nearly 60% of participants worked in agriculture. Many resided close to farmlands and were regularly exposed to pesticides, chemicals, agricultural runoff, and mosquitoes.

In the interviews, participants discussed health concerns related to agricultural labor, such as heat-related illness, musculoskeletal ailments and injuries, skin disorders, respiratory illness, and trauma. They expressed their concerns about environmental exposures related to agriculture and the nearby Salton Sea, a land-locked highly saline lakebed, and offered solutions to improve the health of their communities.

Respiratory illness in the ECV is disproportionately high, affecting about 20% of children living along the Salton Sea. Study participants said they were aware of the negative effects of the Salton Sea on their health. 

“Farm work exposes laborers to heat, cold, and ultraviolet rays, increasing the risk to health,” Cheney said. “Farmworkers have more exposure to pesticides than non-agricultural workers, which can increase risk for skin disease, vision problems, and respiratory-associated illness.”

Cheney added that the kind of work the farmworkers do — picking of crops, heavy lifting, and standing or kneeling for long periods — can cause injuries and chronic pain. 

“The fast-paced, high-risk working environment can affect mental health,” she said. 

The study found many farmworkers stay quiet when it comes to unsafe workplace conditions and injuries because they fear losing their jobs. Many farmworkers lack health insurance and have little access to medical facilities, sick pay, and transportation. Most are not fluent English. Indeed, the situation of rural farmworkers has not changed significantly since the farm labor leader and civil rights activist Cesar Chavez brought attention in the 1960s to the poor living and working conditions endured by farm workers.

“Much of the lack of change is tied to structural level inequities produced by macro-level processes, neoliberal economic and political policies, that extend beyond what individuals or communities can do and reflect the values of governments,” Cheney said. “An example is NAFTA, the North American Free Trade Agreement of 1994. What we know is NAFTA compromised the financial stability of small-scale farms in Mexico, the primary occupation in many rural regions of Mexico. Some estimates suggest more than 3 million people involved in agricultural labor lost their jobs and their livelihood.”

Cheney explained that the EVC is home to a large population of Purépecha, an indigenous group from Michoacán Mexico. 

“Living in the valley and working in the fields, they make up an incredibly vulnerable community as many cannot speak Spanish or English,” she said. “They speak their native indigenous language of Purépecha and are undocumented. They choose farm labor because they don’t need language or technical skills to be pickers. This, though, is the lowest ranking position in agricultural labor and least paid.”

According to Cheney, structural level interventions — interventions that change the political and economic landscape — are needed to effect positive change in the lives of farm workers.

“We need to move away from neoliberal policies that privilege those already in positions of power, open the border between US and Mexico so that those crossing the border are not labelled as ‘illegal’ and have the opportunity to find stable employment, access educational and social opportunities for themselves and their families,” she said. “Such an approach also aligns with the thinking of NAFTA — open the borders for trade to eliminate tariffs. We, too, should open the border for human migration to eliminate inequities.”

Cheney was joined in the study by Tatiana Barrera and Katheryn Rodriguez of UCR; and Ana María Jaramillo López of the College of the Northern Border, Tijuana, Mexico.

The research was funded by the Research Program on Migration and Health.

The title of the research paper is “The Intersection of Workplace and Environment Exposure on Health in Latinx Farm Working Communities in Rural Inland Southern California.”

The University of California, Riverside is a doctoral research university, a living laboratory for groundbreaking exploration of issues critical to Inland Southern California, the state and communities around the world. Reflecting California's diverse culture, UCR's enrollment is more than 26,000 students. The campus opened a medical school in 2013 and has reached the heart of the Coachella Valley by way of the UCR Palm Desert Center. The campus has an annual impact of more than $2.7 billion on the U.S. economy. To learn more, visit www.ucr.edu.

Universities, rich in data, struggle to capture its value, study finds

UCLA–MIT Press research finds pervasive lack of data infrastructure, strategy in U.S. higher ed

Peer-Reviewed Publication

THE MIT PRESS

Universities are literally awash in data. From administrative data offering information about students, faculty and staff, to research data on professors’ scholarly activities and even telemetric signals — the functional administrative data gathered remotely from wireless networks, security cameras and sensors in the course of daily operations — that data can be an invaluable resource.

But a new study by researchers at UCLA and the MIT Press, published Dec. 23 in the journal Science, finds that universities face significant challenges in capturing such data, and that they severely lag the private sector and government entities in using data to solve challenges and inform strategic planning.

“This new research shines a bright light on the ways in which universities are data rich and data poor — and sometimes intentionally data blind,” said Christine L. Borgman, distinguished research professor at the UCLA School of Education & Information Studies and one of the study’s authors. “They are struggling to capture and exploit the true value of their data resources and reluctant to initiate the conversations necessary to build consensus for data governance.”

The study, co-authored by Amy Brand, director and publisher of the MIT Press, is based on a dozen interviews with provosts, vice provosts, university librarians and other senior officials engaged in university data governance and management. The researchers found that although universities have made sporadic initiatives to integrate systems and reduce redundancies in academic data management, most still lack needed coordination and expertise.

The respondents expressed concerns about commercial control of their internal systems and continuing tensions about local capacity for data-informed planning. Many also said they felt handicapped by the lack of databases of record — centralized data repositories — and by the lack of coordinated information management strategies and administrators with data science training and skills.

The study also contends that universities have been slower than other economic sectors in creating senior positions such as chief data officers to coordinate data quality, strategy, governance and privacy matters.

“Our study sought to identify sources of these tensions along with innovative solutions adopted or under development within the academy,” Brand said. “We unexpectedly found a pervasive void of infrastructure thinking and a relatively limited set of data-informed planning successes.”

Almost all respondents said they wanted to be able to better integrate data among departments and schools within their institutions, and to make data from various sources work better when integrated with other data systems. For example, for university libraries to best serve student and faculty researchers, they might need to gather information about academic courses from the institution’s internal systems, and use or merge it with data from external parties such as publishers or public or private sector organizations.

University leaders said they could make better strategic decisions about hiring and curriculum if they had more comprehensive data on faculty research, prospective students, research funding, higher-education policy trends and competitive intelligence about other universities. But data that would help guide decision-making is often inaccessible because of data governance practices or friction among units, departments or schools within a university. And such data might be accessible but unexploited because of a lack of staff expertise.

The findings underscore the need for system and institutional leadership that encourages a broad view of data infrastructure and policies, senior-level personnel with the authority and budgets to help universities capture and use their data more effectively, and greater involvement by faculty and others who are involved in determining how data is used.

To address the issues raised by the research, the authors suggest that universities could expand investments in infrastructure that would improve access, integration and intelligence — the ability to gather, analyze and gain insight. Institutions could also bolster their data management capacity — training personnel and developing career paths for them, for example. Doing so, the authors write, would improve universities’ abilities to manage a range of data, and to mine data for strategic, policy, social, cultural and technical insights.

“Data-informed decision-making provides opportunities to promote transparent governance; advance fairness and equity for faculty, students, and staff; and save money,” the authors write. “We encourage university leaders to embrace more objective and transparent data-informed models for decision-making.”

Designing with DNA

Software lets researchers create tiny rounded objects out of DNA. Here’s why that’s cool

DURHAM, N.C. -- Marvel at the tiny nanoscale structures emerging from research labs at Duke University and Arizona State University, and it’s easy to imagine you’re browsing a catalog of the world’s smallest pottery.

A new paper reveals some of the teams’ creations: itty-bitty vases, bowls, and hollow spheres, one hidden inside the other, like housewares for a Russian nesting doll.

But instead of making them from wood or clay, the researchers designed these objects out of threadlike molecules of DNA, bent and folded into complex three-dimensional objects with nanometer precision.

These creations demonstrate the possibilities of a new open-source software program developed by Duke Ph.D. student Dan Fu with his adviser John Reif. Described December 23 in the journal Science Advances, the software lets users take drawings or digital models of rounded shapes and turn them into 3D structures made of DNA.

The DNA nanostructures were assembled and imaged by co-authors Raghu Pradeep Narayanan and Abhay Prasad in professor Hao Yan’s lab at Arizona State. Each tiny hollow object is no more than two millionths of an inch across. More than 50,000 of them could fit on the head of a pin.

But the researchers say these are more than mere nano-sculptures. The software could allow researchers to create tiny containers to deliver drugs, or molds for casting metal nanoparticles with specific shapes for solar cells, medical imaging and other applications.

To most people, DNA is the blueprint of life; the genetic instructions for all living things, from penguins to poplar trees. But to teams like Reif’s and Yan’s, DNA is more than a carrier of genetic information -- it’s source code and construction material.

There are four “letters,” or bases, in the genetic code of DNA, which pair up in a predictable way in our cells to form the rungs of the DNA ladder. It’s these strict base-pairing properties of DNA -- A with T, and C with G -- that the researchers have co-opted. By designing DNA strands with specific sequences, they can “program” the strands to piece themselves together into different shapes.

The method involves folding one or a few long pieces of single-stranded DNA, thousands of bases long, with help from a few hundred short DNA strands that bind to complementary sequences on the long strands and “staple” them in place.

Researchers have been experimenting with DNA as a construction material since the 1980s. The first 3D shapes were simple cubes, pyramids, soccer balls -- geometric shapes with coarse and blocky surfaces. But designing structures with curved surfaces more akin to those found in nature has been tricky. The team’s aim is to expand the range of shapes that are possible with this method.

To do that, Fu developed software called DNAxiS. The software relies on a way to build with DNA described in 2011 by Yan, who was a postdoc with Reif at Duke 20 years ago before joining the faculty at Arizona State. It works by coiling a long DNA double helix into concentric rings that stack on each other to form the contours of the object, like using coils of clay to make a pot. To make the structures stronger, the team also made it possible to reinforce them with additional layers for increased stability.

Fu shows off the variety of forms they can make: cones, gourds, clover leaf shapes. DNAxiS is the first software tool that lets users design such shapes automatically, using algorithms to determine where to place the short DNA “staples” to join the longer DNA rings together and hold the shape in place.

“If there are too few, or if they're in the wrong position, the structure won't form correctly,” Fu said. “Before our software, the curvature of the shapes made this an especially difficult problem.”

Given a model of a mushroom shape, for example, the computer spits out a list of DNA strands that would self-assemble into the right configuration. Once the strands are synthesized and mixed in a test tube, the rest takes care of itself: by heating and cooling the DNA mixture, within as little as 12 hours “it sort of magically folds up into the DNA nanostructure,” Reif said.

Practical applications of their DNA design software in the lab or clinic may still be years away, the researchers said. But “it's a big step forward in terms of automated design of novel three dimensional structures,” Reif said.

This research was supported by the National Science Foundation (1909848, 2113941, 2004250, 1931487).

Automated Design of 3D DNA Origami With Non-Rasterized 2D Curvature

Penalties, corruption and legislation are failing to deter harmful gas flaring in Nigeria, study shows

Peer-Reviewed Publication

UNIVERSITY OF EXETER

Legislation is failing to end gas flaring in Nigeria which is harming the environment and people’s health, a new study warns.

Legal penalties for oil companies are ineffective and are not weighty enough to be a deterrent, making it cheaper and easier to pollute air and water.

An expert has warned legislative loopholes that give the government discretionary powers to grant gas flaring permits corruption and can be abused by the oil companies.

Nigeria currently contributes significantly to the total amount of greenhouse gases produced in Africa through emissions from its oil and gas industry in the Niger Delta.

The study, by Dr Urenmisan Afinotan from the University of Exeter Law School, shows how efforts to stop gas flaring in the Niger Delta from the 1960s till date have been superficial because they include weak penalties, convenient loopholes and the granting of wide discretion to the Minister of Petroleum and seem to be driven by economic gains and not climate change considerations.

Judicial attempts at combating climate change through the stopping of gas flaring have yielded better results. However, the judicial posture of the courts in Nigeria still seem to favour the economic interests of the government over climate change considerations.

Nigeria has legislative, regulatory and judicial measures in place to achieve its international commitments on combating and mitigating climate change. However, until very recently, there was no specific legal framework covering climate change in Nigeria. The recently enacted Nigeria Climate Change Act (December 2021) is still too nascent to assess its effectiveness in mitigating climate change in Nigeria. 

Gas flares are produced when the extra gases from crude oil drilling and production processes are burned off into the atmosphere. Nigeria is a significant contributor to approximately 65 per cent of the total amount of gas flared globally, flaring about 60 per cent of its associated gas, effectively placing it as the country with the worst record of gas flaring in the world.

There have been a few regulatory attempts to stop gas flaring in the Niger Delta communities since 1969. Most recently the Petroleum Industry Act (PIA), 2021) said oil companies with oil prospecting licences and leases should submit a viable feasibility study for associated gas utilization within five years of commencing operations. This failed to discourage gas flaring before the preparation of the feasibility study or impose penalties for gas flaring before and after submission of the study. This invariably meant that oil companies were free to flare gas, without any penalties, for five years.

The Associated Gas Re-Injection Act (AGRA) gives the Minister of Petroleum discretion to permit the flaring of gas where they believe re-injection or utilization of the gas is unfeasible. This left the door open for the oil companies to corruptly obtain gas flaring permits and licences.

The Associated Gas Re-Injection (Continued Flaring of Gas) Regulations (AGRA Regulations) permitted gas flaring under certain conditions and prescribed absurdly low fines that made it more economically viable for the oil companies to flare associated gas rather than re-injecting it or utilizing it. These conditions or exemptions automatically exempted about 86 out of a possible 155 oil fields owned by the multinational oil companies, from regulations or the penalties. The AGRA Regulations failed to have any impact in the cessation of gas flaring and utilization or re-injection of gas.

Even though it has been reported that the percentage of gas flared in Nigeria has reduced since 2002 and now stands at 10 percent as of 2018 there are reports of new gas flaring sites being constructed by oil companies like Shell, on oil fields in the Niger Delta since 2013.

Nigeria’s new National Gas Policy (NGP) aimed to end gas flaring by the year 2030. Associated regulation provides a legal framework for the protection of the Niger Delta communities and the broader Nigerian environment from the deleterious effects of gas flaring and climate change. It also has the potential to help derive social and economic benefits from associated gas which would normally be flared and wasted during oil production. The regulations empower the Federal Government to appropriate all flare gas held by oil producing companies that hold oil prospecting licences, leases and marginal fields.

Dr Afinotan said: “A new gas flaring commercialization scheme could drastically reduce gas flaring in the Niger Delta and generate gas revenues for the Federal Government.

“It is concerning that the discretionary power of the Minister to grant permits to oil companies to flare gas, as was present in the AGRA, has also been retained in the 2018 Flare Gas Regulations. Such discretionary powers are capable of being corrupted or exploited by the oil companies with their financial power and influence, into getting permits from the Minister using his discretionary powers.

“Only time will tell, especially when the courts are called upon to interpret the provisions of the Regulation. Gas flaring is still a daily occurrence in the Niger Delta.”

The Petroleum Industry Act - passed into law in August 2021 after more than a decade of legislative stalling - does not unequivocally proscribe gas flaring but requires oil field operators to submit a ‘natural gas flare elimination and monetisation plan’ within 12 months of securing a license to operate. Gas flaring is still permitted albeit under certain conditions. This has been regarded as another half-hearted attempt to stop gas flaring in Nigeria.

The study analyses recent oil-related cases heard by the Nigerian judiciary which have prioritised the economic benefits and interests of the deleterious oil and gas industry over the negative effects the industry has on the environment and the lives of the inhabitants of the host communities.

How serious is Nigeria about climate change mitigation through gas flaring regulation in the Niger Delta?

A seventeen-year landmark study finds that group meditation decreases US national stress

World Journal of Social Science publishes study showing that group practice of the TM and TM-Sidhi techniques by √1% of a population decreased multiple stress indicators in the U.S.. Scientists call for a group to create world peace.

Every year during 2000 to 2006 there were tens of thousands of stress-related tragedies in the U.S.. Official statistics from the FBI and Centers for Disease Control indicate that there were 15,440 murders, 93,438 rapes, and 86,348 child and adolescent deaths from accidents each year to give a few examples. The current study is the longest and most comprehensive of 50 studies to demonstrate what has been named the Maharishi Effect, in honor of Transcendental Meditation (TM) and Maharishi International University (MIU) founder Maharishi Mahesh Yogi.

The results can be seen in the chart below. The blue line indicates that during the Baseline period of 2000 to 2006 the size of the TM and TM-Sidhi group located at Maharishi International University in Fairfield, Iowa increased to reach the √1% of the U.S. population (1725 people) and stayed there for five years during the Demonstration period from 2007 to 2011. All stress indicators immediately started decreasing. In the Post period when the size of the group size began to decline the rate of decrease in stress slowed and then it reversed and began to increase.

(See Image 1) 

IMAGE 1: Size of the MIU TM and TM Sidhi group (blueline), eight indices of stress in the United States represented by the lines in different colors, and the US stress index, the mean of all eight variables indicated by the red line.

Lead author Dr. David Orme Johnson said: “What is unique about this study is that the results are so visually striking and on such a large scale. We see reduced stress on multiple indicators at the predicted time for the entire United States over a five-year period. And when the size of the group declined, national stress began increasing again. Clearly, the group was causing the effect.”

Co-author Dr. Kenneth Cavanaugh commented: “This study used state-of-the-art methods of time series regression analysis for eliminating potential alternative explanations due to intrinsic pre-existing trends and fluctuations in the data. We carefully studied potential alternative explanations in terms of changes in economic conditions, political leadership, population demographics, and policing strategies. None of these factors could account for the results.”

The fact that all variables started decreasing only after the square root of one percent of the U.S. was reached indicates a phase transition. Like when water does not turn to ice until 32◦ F is reached, national stress did not start decreasing until the U.S. √1% transition threshold was achieved.

The chart shows that in 2013 when the size of the TM and TM-Sidhi group quickly dropped all stress indicators abruptly increased. Apparently, the rapid drop in national coherence shook the nation.

The scientists used regression analysis to estimate how many deaths and events were reduced by the meditator group. For example, image 2 shows the red dotted line representing the Baseline trend projected into the Demonstration and Post periods. During the Demonstration period drug-related deaths (the black line) fell to 14% below their Baseline trend and were another 15 % lower during the Post period, for a total of 79,941 fewer drug deaths. The chart also shows that in the absence of the coherence creating group drug deaths eventually returned to their Baseline level.

(See Image 2)

TABLE: RESULTS OF REGRESSION ANALYSES. The first column shows the number of events per year during the Baseline period (Intercept). The second column shows the change per year during the Baseline (Slope). The third, fourth, fifth, and sixth columns show the thousands of events averted during the Demonstration, during the Post periods, the total events averted, and percent change, respectively. The last column shows the estimated total events averted by each individual participant in the MIU TM and TM-Sidhi group.

(See Table)

The finding that the effect was holistic, causing all variables to move up and down together, supports the theory expressed by both Maharishi from the Vedic perspective and by quantum physicist and MIU president Dr. John Hagelin from quantum field theory that the TM and TM-Sidhi groups are creating coherence in collective consciousness from the unified field level of natural law. This is big. It is evidence of the existence of the unified field from a completely different approach than using particle accelerators and detecting gravity waves.

This discovery of the unified field is more than just an intellectual knowledge. It is arguably the most immediately highly practical technological discovery in the history of science. The invention of the wheel mobilized humanity. The printing press, radio, the telephone, the internet, and satellites increased our ability to communicate with each other across vast distances and time. The discovery of DNA opened our minds to the subtle mechanics of natural law underlying the evolution and growth of all life forms. These are among the greatest scientific discoveries of all time. But what discovery can reduce human suffering as comprehensively as group meditation?

The paper reviews the many concepts of collective consciousness as they have occurred throughout history in the sciences and humanities. None have practical applications as Maharishi’s does and none have been so empirically verified.

The paper discusses Maharishi’s theory, which holds that every individual automatically contributes to collective consciousness and reciprocally, collective consciousness influences every individual. This is universally true whatever the form of government—democracy, republic, monarchy, communism, or dictatorship.

It is essential for every individual to use evidence-based technologies to reduce their own stress and at the same time, the responsibility of every government to provide these technologies to everyone.

The paper summarizes the hundreds of studies showing that practice of TM increases coherence in the individual, as indicated by such measures as increased brain coherence, decreased anxiety, depression, and anger, increased creativity, increased IQ and emotional and social intelligence, and decreased PTSD symptoms, prison recidivism, drug and alcohol addictions, and sickness rates in all categories of disease. More coherent individuals form a more coherent society.

A grant for 75 million dollars from the Howard and Alice Settle Foundation provided stipends for participants to be in the group and provided funding to bring several hundred visiting TM-Sidhi experts from India to further augment the MIU group. Dr. Orme-Johnson commented: “This is a lot of money, but the savings from the 10% reduction in crimes would save over 200 billion dollars, not to mention all the other savings from reducing other sources of stress in the country.”

The paper concludes with a call to create a permanent √1% group for the whole world, 8,000 participants practicing the TM and TM-Sidhi program together in one place. And as an engineering safety factor, a √1% group on every continent is needed. The world is so interconnected, no one is safe until everyone is safe, all living in harmony.

Researchers have uncovered a previously hidden heating process that helps explain how the atmosphere that surrounds the Sun called the “solar corona” can be vastly hotter than the solar surface that emits it.

The discovery at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) could improve tackling a range of astrophysical puzzles such as star formation, the origin of large-scale magnetic fields in the universe, and the ability to predict eruptive space weather events that can disrupt cell phone service and black out power grids on Earth. Understanding the heating process also has implications for fusion research.

Breakthrough

“Our direct numerical simulation is the first to provide clear identification of this heating mechanism in 3D space,” said Chuanfei Dong, a physicist at PPPL and Princeton University who unmasked the process by conducting 200 million hours of computer time for the world’s largest simulation of its kind. “Current telescope and spacecraft instruments may not have high enough resolution to identify the process occurring at small scales,” said Dong, who details the breakthrough in the journal Science Advances.

The hidden ingredient is a process called magnetic reconnection that separates and violently reconnects magnetic fields in plasma, the soup of electrons and atomic nuclei that forms the solar atmosphere. Dong’s simulation revealed how rapid reconnection of the magnetic field lines turns the large-scale turbulent energy into small-sale internal energy. As a consequence the turbulent energy is efficiently converted to thermal energy at small scales, thus superheating the corona.

“Think of putting cream in coffee,” Dong said. “The drops of cream soon become whorls and slender curls. Similarly, magnetic fields form thin sheets of electric current that break up due to magnetic reconnection. This process facilitates the energy cascade from large-scale to small-scale, making the process more efficient in the turbulent solar corona than previously thought.”

When the reconnection process is slow while the turbulent cascade is fast, reconnection cannot affect the transfer of energy across scales, he said. But when the reconnection rate becomes fast enough to exceed the traditional cascade rate, reconnection can move the cascade toward small scales more efficiently.

It does this by breaking and rejoining the magnetic field lines to generate chains of small twisted lines called plasmoids. This changes the understanding of the turbulent energy cascade that has been widely accepted for more than half a century, the paper says. The new finding ties the energy transfer rate to how fast the plasmoids grow, enhancing the transfer of energy from large to small scales and strongly heating the corona at these scales.

The new discovery demonstrates a regime with an unprecedentedly large magnetic Reynolds number as in the solar corona. The large number characterizes the new high energy transfer rate of the turbulent cascade. “The higher the magnetic Reynolds number is, the more efficient the reconnection-driven energy transfer is,” said Dong, who is moving to Boston University to take up a faculty position.

200 million hours

“Chuanfei has carried out the world’s largest turbulence simulation of its kind that has taken over 200 million computer CPUs [central processing units] at the NASA Advanced Supercomputing (NAS) facility,” said PPPL physicist Amitava Bhattacharjee, a Princeton professor of astrophysical sciences who supervised the research. “This numerical experiment has produced undisputed evidence for the first time of a theoretically predicted mechanism for a previously undiscovered range of turbulent energy cascade controlled by the growth of the plasmoids.

“His paper in the high-impact journal Science Advances completes the computational program he began with his earlier 2D results published in Physical Review Letters. These papers form a coda to the impressive work that Chuanfei has done as a member of the Princeton Center for Heliophysics,” a joint Princeton and PPPL facility. “We are grateful for a PPPL LDRD [Laboratory Directed Research & Development] grant that facilitated this work, and to the NASA High-End Computing (HEC) program for its generous allocation of computer time.”  

The impact of this finding in astrophysical systems across a range of scales can be explored with current and future spacecraft and telescopes. Unpacking the energy transfer process across scales will be crucial to solving key cosmic mysteries, the paper said.

Funding for the paper comes from the DOE Office of Science (FES) and NASA, with computer resources provided by the NASA HEC together with the National Energy Research Scientific Computing Center, a DOE Office of Science user facility, and the NSF-sponsored Computational and Information Systems Laboratory. Co-authors of the paper were researchers at PPPL, Princeton and Columbia Universities, and the NASA Ames Research Center.

PPPL, on Princeton University's Forrestal Campus in Plainsboro, N.J., is devoted to creating new knowledge about the physics of plasmas — ultra-hot, charged gases — and to developing practical solutions for the creation of fusion energy. The Laboratory is managed by the University for the U.S. Department of Energy’s Office of Science, which is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
