Energy transitions: why countries respond differently to the same problem

Published: November 17, 2022

Russia’s invasion of Ukraine upended global energy markets. Sanctions on Russian exports and the suspension of gas deliveries to several European countries sent oil and gas prices skywards.

The magnitude of the shock is reminiscent of the 1970s oil crisis, where an embargo imposed on the sale of oil by members of the Organisation of Petrol Exporting Countries led to global fuel shortages and elevated prices. Governments sought to reduce their dependence on imported oil by transitioning their energy systems towards domestic resources. Facing the current crisis, countries are also moving away from importing energy while pursuing decarbonisation.

In both instances, some have been more successful than others in pursuing energy reform. My colleagues and I analysed the response of industrialised democracies to the 1970s crisis, climate change and to the current energy crisis. We found that a country’s ability to pursue major energy reforms hinges on the government’s capacity to defuse political opposition.

Reforms are costly for both households and businesses. For example, a tax on oil consumption increases the cost of energy for consumers while policies that require businesses to switch to renewable energy impose costs on firms and disrupt fossil fuel company profits. Politicians therefore tend to face strong opposition from both consumers and producers when embarking on energy transitions.

To defuse opposition, we find that governments have two options.

1. Insulation


The first is to insulate the policymaking process from voter discontent and business interference. A country’s political institutions shape the extent to which this can be achieved.

Proportional electoral rules, where the distribution of seats corresponds with the proportion of votes for each party, can protect governments from voter backlash. The likelihood that a small change to vote shares will remove a government from power is reduced under this system.

In countries with strong bureaucracies, civil servants enjoy substantial discretion to intervene in the economy to achieve policy goals. Their long-term job security means they face less risk of termination or demotion for upsetting powerful interest groups. This insulates policymaking and can enable governments to enact reform over the wishes of entrenched business opposition.

France’s production of nuclear energy increased 14-fold between 1972 and 1985. Reforms were carried out by a strong and centralised public administration with the authority to implement policy change over the opposition of business and affected communities. The national utility, Electricité de France (EDF), was also owned by the state. This offered the French government additional insulation and granted it control over the direction of the country’s electricity sector.

Although EDF is no longer state owned, the French government holds a majority stake in the company. This allows France to pursue a similar response to the current energy crisis. The French president, Emmanuel Macron, called for the construction of 14 new nuclear reactors earlier this year.

2. Compensation

Governments can also secure support for energy reform by using compensation. Countries with developed welfare states can use existing social policy to soften the impact of energy price increases for households. Governments that enjoy close relationships with business can also negotiate with industry and exchange compensation for their support.

Compensatory bargaining with industry associations and labour unions allowed Germany to transition away from oil in the 1970s. From 1973 to 1985, subsidy schemes enabled a 30% increase in coal power and a 13-fold increase in nuclear energy generation. At the same time the government used the welfare system to ease the burden of higher energy costs for households through financial support.

Germany is again using compensatory strategies as it transitions away from fossil fuels. The country negotiated the “coal compromise” between 2018 and 2020. The scheme provides €40 billion (£35 billion) to coal companies and coal mining regions in return for political support for the plan to phase-out coal production by 2038.
Retreat

When governments can pursue neither insulation nor compensation, they let markets drive change.

Majoritarian electoral rules, a small welfare state and limited coordination between the state and business have restricted the ability of US governments to pass costly energy reforms.

Attempts to reduce dependence on imported oil during the 1970s – from gasoline taxes to energy efficiency regulations – withered in the face of political opposition. The case is similar for climate policy. Successive US governments have struggled to pass major reforms, whether it be an energy tax in 1993 or the then US president Barack Obama’s plan to impose emissions limits on power plants in 2015.

In response to the current energy crisis, the focus has been on markets. The US government has attempted to reduce energy prices by expanding domestic oil production and lobbying Saudi Arabia to increase its oil output.

Yet even countries with a low capacity for insulation or compensation can still pursue energy reform. To do this, policies must not impose visible and direct costs on society. A recent example is the US’s Inflation Reduction Act. Instead of reducing emissions through taxation, penalties or fines, the legislation relies on subsidies for clean technologies funded by general tax revenues. By using carrots and no sticks, many of the political difficulties associated with major energy reforms can be avoided.

Energy transitions are deeply political processes. While the current energy crisis is an opportunity to accelerate the transition towards clean energy, the scale and pace of such change will depend on the capacity of governments to defuse political opposition.

Danielle Smith’s byelection win not as decisive as expected, experts say

Story by Demi Knight • Nov 8

Seven years after leaving the legislature, Alberta Premier Danielle Smith has reclaimed a seat.

Smith beat out four opponents in the byelection for the constituency of Brooks-Medicine Hat on Tuesday to win her seat.

A SURE FIRE RIGHT WING MORMON, REFORM CHURCH, RIDING IN BROOKS BUT MEDICINE HAT IS A CITY AND THEY VOTED AGAINST SMITH

It was a result that political scientists across the province weren't surprised to hear.

"I think we certainly expected that Danielle Smith would win the seat," said Trevor Harrison, a political scientist at the University of Lethbridge. "It would have been a total shock and thrown the UCP into quite a conundrum had she not won."

However, sitting just below 55 per cent of the votes at of 10:30 p.m. Tuesday evening, her win wasn't as large as some party members may have hoped for.

"I think certainly the UCP and Danielle Smith herself are breathing a sigh of relief, a win is a win. But it is very low," Harrison said.


"This was a byelection in the heart of UCP support, rural Alberta, so one is happy to win the election, but does it send a message somehow that perhaps Danielle Smith is not as saleable out there as the UCP would hope? That's something for the party itself to really mull over in the next little while."

Premier Smith says she doesn’t want her or health minister to bottleneck health decisions

Lori Williams, a political scientist with Mount Royal University, agreed.

"This is nowhere near the decisive win that she would have wanted and probably expected," Williams said.

"She ran in this riding, she wanted to have that decisive victory, and this isn't it."


However, Harrison said there could be several reasons as to why her win was smaller than expected.

"It's also possible that some of the other parties were particularly motivated to come out and vote against Danielle Smith," Harrison said. "Hence, that might explain some of the difference in the percentages for the various candidates."

Winning her seat in legislature is something that poli-sci professors agree was necessary for Smith to move forward in her political career.

"It would have been very difficult to govern as a premier without sitting in the legislature," Harrison said. "(Danielle Smith) clearly has a pretty robust agenda of things that she wants to do and so presumably, she can do those things better when she's in the legislature."

"Well, it’s a win. And she will take a win. And she'll try to translate that into support in a place in the legislature and the ability to actually move her agenda, whatever that happens to be," Williams said.

Advance voting numbers released in Brooks-Medicine Hat byelection

In advance polling, fewer eligible voters in the riding of Brooks-Medicine Hat cast their ballot when compared to the last general election.

Elections Alberta said 4,231 out of 34,060 eligible voters cast their ballots in advance polls this year, which is about 12.4 per cent of eligible voters.


Harrison said low voter turnout for byelections is nothing new, however, he added he was surprised that Premier Smith's status didn't boost numbers at this year's polls.

"Byelections generally don't get as many people out, sometimes we get as low as 35-40 per cent of people turning out," Harrison said. "In this case, however, given that you do have the premier running in the riding, you would expect that the votes should be actually pretty high, so I'm not quite sure what it says about voter apathy."

'Warped stance on COVID': Fired Alberta Health Services board member calls out Smith

Dean Bennett
The Canadian Press
Updated Nov. 18, 2022 

EDMONTON - A health system leader fired by Premier Danielle Smith has fired back in an open letter, saying her abusive, divisive attacks, blended with “warped” anti-science beliefs, make her a poor excuse for a leader and one literally putting Albertans in harm's way.

“(Albertans) are entitled to governance that is principle-based, respects decency and inspires confidence in its citizens,” Tony Dagnone said in the letter issued Friday.

He was one of 11 members of the governing board of Alberta Health Services recently fired by Smith.

“The current premier defies all those aspirations as she spews wacko accusations at Alberta Health Services and its valued workforce,” he wrote.

The premier has chosen to “play to her misguided followers who rant against science and academic medicine under the veiled guise of freedom,” Dagnone said in the letter.

“Her warped stance on COVID, which I remind the premier was and is a public health issue not a political punching bag, is nothing short of borderline dereliction when the lives of AHS staff and Albertans are at stake,” Dagnone wrote.

“In light of her unhinged public pronouncements, the premier represents the bleakest of role models for women who aspire to be accepted in positions of influence and leadership.

“Why would any self-respecting graduate pursue their health-care vocation in a province led by an anti-science premier?”

Dagnone could not be immediately reached for comment.

He and the other AHS governing board members were fired Thursday by Smith, fulfilling a promise she made in her successful summer campaign to win the leadership of the United Conservative Party and become premier.

The 12th board member, Deborah Apps, quit after Smith won the UCP leadership race in early October, citing concern for the disruption Smith promised to impose on a fragile health system.

Alberta Health Services is the agency of more than 100,000 staff tasked with delivering front-line care in the province.

Smith blamed both AHS and Dr. Deena Hinshaw, the chief medical officer of health, for bad advice and execution in the pandemic, leading to jammed hospital wards and forcing the province to impose freedom-limiting vaccine mandates and passports.

Hinshaw was removed from her job earlier this week.

The board has been replaced by Dr. John Cowell, who is charged with fixing multiple stress points in the system, including surgery wait times, ambulance bottlenecks, doctor shortages and overcrowded emergency wards.

Dagnone, an Order of Canada winner with four decades of work in hospital and health administration, said he has no political affiliations and felt compelled to defend AHS staff.

“I witnessed the extraordinary collective will of our health-care providers confronting the unimaginable COVID,” he wrote.

“All deserve our respect and gratitude, however, the premier chooses instead to vilify those who were saving Albertans.”

Smith spoke Friday at a meeting of the Calgary Chamber of Commerce but declined to speak with reporters. Her office, in a statement, said the province had to take action to address pressing issues in the health system.

“This decision (to fire the board) was not personal, this is about better outcomes for Albertans, and we are grateful for the work done by the AHS board,” reads the statement.

Smith has said there will be no health restrictions or vaccine mandates during future waves of COVID-19. And she has said there will be no mask mandates in schools currently dealing with respiratory viral illnesses that are spiking absentee rates and filling children's hospitals.

Smith has publicly embraced alternative approaches to COVID-19, including herd immunity and the since-debunked COVID-19 treatment ivermectin.

Earlier this month, she announced she wants to hear from Paul Alexander, a controversial critic of mainstream science who has characterized COVID-19 vaccines as “bioweapons.”

“The premier is taking her nonsense to a new level by inviting a former Trump adviser (Alexander) who has been universally scorned for promoting medical quackery,' wrote Dagnone.

“If (she) persists in vocalizing false, conspiratorial and unfounded claims, she will be responsible for putting health-care providers and Albertans needlessly in harm's way.

“Her loose and corrosive words appear to satisfy her need for bizarre musings that can and will ultimately impact people's lives.”

NDP health critic David Shepherd, responding to Dagnone's letter, echoed the concerns.

“(Smith) will continue to blame health-care workers for the current state of care while taking no responsibility herself for the impact of the dangerous misinformation and conspiracy theories she promotes,” Shepherd said.

“Her reckless politicization of our public health-care system will make it harder to recruit and retain health professionals and for Albertans to access care.”

Smith fails to back up Indigenous heritage claims after report finds no proof

Updated Nov. 18, 2022 

There was an eruption of laughter amongst First Nations people Friday at an Edmonton hotel when a panel of Chiefs was asked about Alberta's premier claiming to have Indigenous heritage.

Danielle Smith has spoken publicly about her Cherokee roots as far back as 2012, and in September she wrote in a tweet that she is "someone with indigenous (sic) ancestry."


But an investigative report published by the Aboriginal People's Television Network (APTN) this week found no records to back her claims, and Smith refused to provide any evidence, or even restate her claims, Friday.

"Premier Smith has heard about her heritage from her loved ones. Her family has spoken for years about their ancestry and she is proud of her family history. The Premier hasn’t done a deep dive into her ancestry but is proud of her roots," her spokesperson wrote.

"What we're realizing is that anybody wants to be a part of that Indigenous community if there's a benefit," Alexis said.

Chief Alexis and others are calling on Smith to stop the sovereignty act and consult with Indigenous people. He suggested the legislation is further proof that the premier's claims are bogus.

"A true Indigenous person would not go against all the Treaty people of this land," he said.

NDP MLA Richard Feehan was at that press conference and said Alexis' words meant far more than his on the topic of Smith's Indigenous claim.

"I think she needs to have a conversation with the First Nations about this," Feehan told reporters.

"Not with people like me or the Opposition. The First Nations chiefs, who are representatives of the people, need to hear from her and she has clearly failed to do that in every possible way."


A spokesperson for Smith said she was not available Friday to take questions from journalists.

A First Nations leader in Alberta is questioning Premier Danielle Smith's claim of Indigenous heritage.

Smith has said she has some Cherokee roots and years ago declared herself as a person of mixed race.

Chief Tony Alexis of Alexis Nakota Sioux Nation, west of Edmonton, said on Friday that a true Indigenous person would not go against treaty people.

He made the comment at a news conference where leaders of Treaties 6, 7, and 8 said they oppose Smith's plan to introduce an Alberta sovereignty act that would allow her government to opt out of federal measures deemed harmful to provincial interests.

When the leaders were asked about Smith's ancestry claim, many in the room erupted with laughter.

"A true Indigenous person would not go against all the treaty people of this land," said Alexis.

"What we're realizing is that anybody wants to be a part of the Indigenous community if there's a benefit."

A story this week by the Aboriginal Peoples Television Network looked into Smith's family tree and found no evidence of the premier being Indigenous. APTN worked with Canadian and Cherokee genealogists and examined U.S. census reports from the late 1800s in it's investigation.

CBC has not independently verified APTN's reporting.

The premier's office issued a statement following the story stating, "Smith hasn't done a deep dive into her ancestry but is proud of her roots."

"Like so many Albertans that have origins from all over the world, Premier Smith has heard about her heritage from her loved ones. Her family has spoken for years about their ancestry and she is proud of her family history."

APTN said Smith claimed to be a person of "mixed-race ancestry" in 2012, when she was leader of the Wildrose Party.

In the legislature that year, APTN said Smith spoke about her great-great-grandmother.

"She was a member of the Cherokee Nation that had been forcibly relocated to Kansas from the southeastern United States in the 1830s by the U.S. government, a terrible stain on the history of America known as the Trail of Tears," Smith said, according to legislative records obtained by APTN.

More recently, Smith declared Indigenous lineage during the United Conservative Party leadership race.

"As someone with Indigenous ancestry, I honour the heritage of Canada's Indigenous Peoples as one of our nation's and province's greatest treasures and strengths," said the tweet from Smith on Sept. 28.

Some false claims of Indigenous ancestry have recently come to light at universities in Canada.

Alexis said there's always a reason for Indigenous identity fraud.

"At the university level, we have people who are not Indigenous who claim that they are Indigenous to gain benefits, to gain bursaries and so on," said the chief.

"There's always something behind it."

National Gallery of Canada lays off chief and Indigenous art curators

The National Gallery of Canada has laid off four senior staff members including Greg A. Hill, its curator of Indigenous art, and chief curator Kitty Scott.

The gallery has experienced a period of uncertainty in the wake of the departure of director Sasha Suda in July. She left only a year after unveiling a strategic plan that placed Indigenous knowledge at the core of the gallery’s mission.

The gallery is currently seeking a new director.

Mr. Hill said he was let go because he disagreed with how the gallery was approaching the new decolonization agenda.

“I want to put this out before it is spun into meaningless platitudes,” Mr. Hill wrote in a post on Instagram Thursday. “The truth is, I’m being fired because I don’t agree with and am deeply disturbed by the colonial and anti-Indigenous ways the Department of Indigenous Ways and Decolonization is being run.”

Mr. Hill did not immediately respond to requests for further comment.

Liliane Lê, the gallery’s vice-president of public affairs, declined to comment on the layoffs.

In an internal memo to staff obtained by The Globe and Mail, interim director Angela Cassie writes: “The work-force changes are the result of numerous factors and were made to better align the gallery’s leadership team with the organization’s new strategic plan. … For privacy reasons, the gallery is not at liberty to discuss details of these departures.”

Mr. Hill, the inaugural Audain senior curator of Indigenous art, had worked at the gallery for 22 years. He is a specialist in Iroquoian languages and culture, and in global contemporary Indigenous art.

“It was, of course, a great surprise,” said Vancouver art collector and philanthropist Michael Audain, who had endowed the Indigenous curatorial job since 2007. “I was under the impression that Greg had done a creditable job of introducing Indigenous art into the gallery, something which was sadly missing when former director Pierre Théberge originally asked me to endow Greg’s position,” he said in an e-mail.

Mr. Audain added that the gallery has sent him a proposal to reorient the endowment, but he has yet to review it.

The gallery has also laid off Ms. Scott, its chief curator and a highly respected advocate for Canadian contemporary art, who previously worked at the Art Gallery of Ontario in Toronto. She worked at the National Gallery in the 2000s – when she made the acquisition of Maman, the giant Louise Bourgeois spider sculpture that sits outside the building – and was brought back to Ottawa by Ms. Suda in 2020.

The other two people to lose their jobs are Stephen Gritt, a veteran staffer and director of conservation and technical research, and Denise Siele, a recent hire as senior communications manager. (The former staffers could not be reached for comment Friday.)

Ms. Cassie, formerly the gallery’s chief strategy and inclusion officer, has served as interim director since Ms. Suda left for a prestigious job as director of the Philadelphia Museum of Art only three years into a five-year term. Ms. Cassie had previously worked at the Canadian Museum of Human Rights in Winnipeg before joining the gallery last year.

A passionate advocate for modernizing art museums, Ms. Suda had brought in the strategic plan, with its emphasis on “interconnection through time and space” and a new motto, ankosé, an Anishinaabemowin word that translates as “everything is connected.”

However, during her tenure, there was also a high turnover of senior staff.

Crack in Earth's magnetic field triggers extremely rare pink auroras witnessed in Norway


Camille Fine

USA TODAY


Want to know what the night sky looks like after a solar storm smashes into earth and rips a hole into the planet’s magnetic field? 

The combination of cosmic events led to a rare explosion of strikingly vivid pink auroras the filled Norway's night sky. The unusual colored light show lasted for around two minutes and was caused by a crack in Earth's magnetic field, enabling highly energetic solar particles, known as solar wind, to enter into the atmosphere on Nov. 3, according to Spaceweather.com

Greenlander tour company guide Markus Varik spotted the auroras at around 6 p.m. while leading a tour group near Tromsø, Norway, Varik told USA TODAY.  Although the pink auroras weren’t the best he’s ever witnessed before, the color's intensity was “super rare” and “almost never happens,” Varik said.   

Varik said he has conducted over 1,000 tours of Norway’s auroras as a guide for over 10 years, but these were the strongest hues of pink and purple he’s witnessed in his entire life.

Varik said that auroras are usually green, the color of oxygen atoms being struck by energetic particles, but purple shades can occur under “rare” conditions when electrons penetrate deep into the atmosphere and collide with molecules of nitrogen. 

Rare pink auroras temporarily filled the skies above Norway after a crack in the Earth's magnetosphere enabled solar wind to penetrate deep into Earth's atmosphere.

“The Northern Lights are always different, never the same. It’s like us, people, completely unique in our own special ways,” Varik said. “When the auoras give us a blessing to be able to experience this kind of phenomena, it always goes very spiritual to me.”

Auroras, usually between 62 and 186 miles above Earth's surface, are formed when streams of solar wind pass around the planet's magnetic field and superheat gases, which then glow in the night sky. 

Auroras are more common at the North and South Poles, areas with weaker shields for cosmic radiation, according to NASA

300 Years of Research: Princeton Scientists Solve a Bacterial Mystery

By  

Bacterial Colonies’ Clumpy Growth

Researchers found that bacteria colonies form in three dimensions in rough shapes similar to crystals.

Bacterial colonies often grow in streaks on Petri dishes in laboratories, but no one has understood how the colonies arrange themselves in more realistic three-dimensional (3-D) environments, such as tissues and gels in human bodies or soils and sediments in the environment, until now. This knowledge could be important for advancing environmental and medical research.

Princeton University team has now developed a method for observing bacteria in 3-D environments. They discovered that when the bacteria grow, their colonies consistently form fascinating rough shapes that resemble a branching head of broccoli, far more complex than what is seen in a Petri dish. 

“Ever since bacteria were discovered over 300 years ago, most lab research has studied them in test tubes or on Petri dishes,” said Sujit Datta, an assistant professor of chemical and biological engineering at Princeton and the study’s senior author. This was a result of practical limits rather than a lack of curiosity. “If you try to watch bacteria grow in tissues or in soils, those are opaque, and you can’t actually see what the colony is doing. That has really been the challenge.”

Datta’s research group discovered this behavior using a ground-breaking experimental setup that enables them to make previously unheard-of observations of bacterial colonies in their natural, three-dimensional state. Unexpectedly, the scientists discovered that the growth of the wild colonies consistently resembles other natural phenomena like the growth of crystals or the spread of frost on a windowpane.

“These kinds of rough, branchy shapes are ubiquitous in nature, but typically in the context of growing or agglomerating non-living systems,” said Datta. “What we found is that growing in 3-D, bacterial colonies exhibit a very similar process despite the fact that these are collectives of living organisms.”

This new explanation of how bacteria colonies develop in three dimensions was recently published in the journal Proceedings of the National Academy of Sciences.  Datta and his colleagues hope that their discoveries will help with a wide range of bacterial growth research, from the creation of more effective antimicrobials to pharmaceutical, medical, and environmental research, as well as procedures that harness bacteria for industrial use.

“At a fundamental level, we’re excited that this work reveals surprising connections between the development of form and function in biological systems and studies of inanimate growth processes in materials science and statistical physics. But also, we think that this new view of when and where cells are growing in 3D will be of interest to anyone interested in bacterial growth, such as in environmental, industrial, and biomedical applications,” Datta said.

For several years, Datta’s research team has been developing a system that allows them to analyze phenomena that are usually cloaked in opaque settings, such as fluid flowing through soils. The team uses specially designed hydrogels, which are water-absorbent polymers similar to those in jello and contact lenses, as matrices to support bacterial growth in 3-D. Unlike those common versions of hydrogels, Datta’s materials are made up of extremely tiny balls of hydrogel that are easily deformed by the bacteria, allow for the free passage of oxygen and nutrients that support bacterial growth, and are transparent to light.

“It’s like a ball pit where each ball is an individual hydrogel. They’re microscopic, so you can’t really see them,” Datta said. The research team calibrated the hydrogel’s makeup to mimic the structure of soil or tissue. The hydrogel is strong enough to support the growing bacterial colony without presenting enough resistance to constrain the growth.

“As the bacterial colonies grow in the hydrogel matrix, they can easily rearrange the balls around them so they are not trapped,” he said. “It’s like plunging your arm into the ball pit. If you drag it through, the balls rearrange themselves around your arm.”

The researchers performed experiments with four different species of bacteria (including one that helps to generate kombucha’s tart taste) to see how they grew in three dimensions.

“We changed cell types, nutrient conditions, hydrogel properties,” Datta said. The researchers saw the same, rough-edged growth patterns in each case. “We systematically changed all those parameters, but this appears to be a generic phenomenon.”

Datta said two factors seemed to cause the broccoli-shaped growth on a colony’s surface. First, bacteria with access to high levels of nutrients or oxygen will grow and reproduce faster than ones in a less abundant environment. Even the most uniform environments have some uneven density of nutrients, and these variations cause spots in the colony’s surface to surge ahead or fall behind. Repeated in three dimensions, this causes the bacteria colony to form bumps and nodules as some subgroups of bacteria grow more quickly than their neighbors.

Second, the researchers observed that in three-dimensional growth, only the bacteria close to the colony’s surface grew and divided. The bacteria crammed into the center of the colony seemed to lapse into a dormant state. Because the bacteria on the inside were not growing and dividing, the outer surface was not subjected to pressure that would cause it to expand evenly. Instead, its expansion is primarily driven by growth along the very edge of the colony. And the growth along the edge is subject to nutrient variations that eventually results in bumpy, uneven growth.

“If the growth was uniform, and there was no difference between the bacteria inside the colony and those on the periphery, it would be like filling a balloon, said Alejandro Martinez-Calvo, a postdoctoral researcher at Princeton and the paper’s first author. “The pressure from the inside would fill in any perturbations on the periphery.”

To explain why this pressure was not present, the researchers added a fluorescent tag to proteins that become active in cells when the bacteria grow. The fluorescent protein lights up when bacteria are active and remains dark when they are not. Observing the colonies, the researchers saw that bacteria on the colony’s edge were bright green, while the core remained dark.

“The colony essentially self-organizes into a core and a shell that behave in very different ways,” Datta said.

Datta said the theory is that the bacteria on the colony’s edges scoop up most of the nutrients and oxygen, leaving little for the inside bacteria.

“We think they are going dormant because they are starved,” Datta said, although he cautioned that further research was needed to explore this.

Datta said the experiments and mathematical models used by the researchers found that there was an upper limit to the bumps that formed on the colony surfaces. The bumpy surface is a result of random variations in the oxygen and nutrients in the environment, but the randomness tends to even out within certain limits.

“The roughness has an upper limit of how large it can grow – the floret size if we are comparing it to broccoli,” he said. “We were able to predict that from the math, and it seems to be an inevitable feature of large colonies growing in 3D.”

Because the bacterial growth tended to follow a similar pattern as crystal growth and other well-studied phenomena of inanimate materials, Datta said the researchers were able to adapt standard mathematical models to reflect the bacterial growth. He said future research will likely focus on better understanding the mechanisms behind the growth, the implications of rough growth shapes for colony functioning, and applying these lessons to other areas of interest.

“Ultimately, this work gives us more tools to understand, and eventually control, how bacteria grow in nature,” he said.
