Newswise — Can you turn manure into a cow, chicken or fish? Texas A&M AgriLife Research scientists are looking to do just that, in a roundabout, circular economy, kind of way.

A three-year, $618,000 grant from the U.S. Department of Agriculture National Institute for Food and Agriculture is funding a study by scientists in the Texas A&M College of Agriculture and Life Science Department of Entomology and Mississippi State University to explore dairy manure clean-up via black soldier flies. The team would then examine the flies’ value as a potential ingredient in livestock, poultry and aquaculture feed.

The project will concentrate on both environmental health and economic benefits of converting dairy waste into protein that could be used for feed. Early data indicate probiotics could be used to accelerate the digestive process in fed animals, increase conversion of waste to insect biomass, decrease greenhouse gases and noxious odors, and reduce concerns about pathogens that might be present in the manure.

The study will be led by Jeff Tomberlin, Ph.D., professor, AgriLife Research Fellow, Presidential Impact Fellow and Center for Environmental Sustainability through Insect Farming director, and Anjel Helms, Ph.D., an assistant professor and chemical ecologist, both in the Department of Entomology.

Heather Jordan, Ph.D., associate professor and microbiologist at Mississippi State University, will examine the resulting larvae and frass, which is the material remaining after larvae digest manure, for microbial diversity and feed safety. Helms’ postdoctoral research associate Amber MacInnis, Ph.D., will lead the day-to-day data collection with the help of students.

“We’re testing the limits of black soldier fly production in conjunction with probiotics to see how efficient they could be for large animal production facilities, in this case dairies,” Helms said. “Manure management is an expense to these producers, and we are testing to see if this is a way to manage that waste and turn it into a productive feed source.”

Turning an expense into a resource

Black soldier fly larvae consume their weight in organic waste daily for a two-week period – around 1 gram or the weight of a single raisin per larva. That may sound insignificant, but those amounts add up when multiplied by millions of black soldier fly larvae.

For example, existing facilities in Europe, Asia and North America can digest 100 tons of waste daily using black soldier fly larvae.

MacInnis’ experiments are done in plastic containers filled with around 18 pounds of manure where 10,000 black soldier fly eggs are placed. The larvae hatch, consume the dairy manure for two weeks and then are harvested, and then the process is repeated.

An important part of the project is to determine how safe harvested larvae are when converted into ingredients for feed. Little is known about pathogen diversity in larvae that consume manure that in turn could impact feed safety. Helms suspects larvae consuming manure are safe for livestock consumption, but the end-product must be certified. 

“This is an exciting study to be a part of because it is problem-solving at its core,” MacInnis said. “These dairies produce an enormous amount of waste. If black soldier flies can be an efficient part of their management process and provide other benefits, that could be a big breakthrough across the industry.”

Layers of potential benefits from waste conversion

Black soldier flies consume organic waste, including manure, but the process of waste conversion leaves room for efficiency improvements.

The study will utilize probiotics to enhance black soldier fly waste conversion of dairy manure and remove more than 50% of nitrogen and potassium from the waste. Helms said the team is working with Jordan to study the probiotic impacts.

Manure conversion by black soldier flies is also expected to provide an environmental benefit beyond reducing reliance on traditional manure management methods like waste storage lagoons.

“There is potential for layers of economic and environmental benefits to incorporating black soldier flies in manure management,” Helms said. “Turning waste into a resource sounds too good to be true, but we are understanding more and more about the ways black soldier flies can solve a lot of problems.”

Philly Whole Foods store becomes first to unionize – a labor expert explains what’s next and how Trump could stall workers’ efforts

Whole Foods workers at the Philadelphia flagship store in the city’s Art Museum area voted to unionize on Jan. 27, 2025. They are the first store in the Amazon-owned grocery chain to do so.

Paul Clark, a professor of labor and employment relations at Penn State University, talked to Kate Kilpatrick, The Conversation U.S. Philadelphia editor, about why this is happening – and why in Philly.

The Whole Foods workers in Philadelphia voted 130-100 in favor of unionizing. What do we know about their grievances?

From what I understand, these workers have felt that compensation, benefits and work conditions were not what they should be. Some are long-standing employees and say they struggle to afford their basic necessities.

Why did the union drive effort succeed now, and in Philly?

In the last five years, there has been a surge in union organizing. There are a number of reasons for this. First is the labor market. Low unemployment emboldens workers to take the risk of organizing a union. If workers feel their employer can’t replace them or that they can easily get a similar job, they are less fearful of angering the employer by trying to organize.

The second reason is that the Biden administration was a labor-friendly administration – perhaps the most in history. The U.S. president appoints a majority of members to the National Labor Relations Board, which interprets and enforces the labor law that governs organizing. Under Biden, the NLRB regularly issued decisions that provided greater protection to workers and held employers accountable when they violated workers’ rights. During Republican administrations, the board’s decisions are generally pro-business and provide less protection to workers. So workers had the wind at their back in that regard.

Also recent polling shows that 70% of Americans approve of unions, compared with less than half of Americans just 15 years ago. The generally favorable view of unions creates a more supportive environment for organizing.

And the last factor is that Generation Z, the youngest group of workers, clearly wants more out of their work and employment than previous generations. So we see a lot of young workers across the country organizing at Starbucks, Trader Joe’s, Apple and now at Whole Foods and other stores.

Why Philadelphia? Philadelphia is a relatively strong union town. The percentage of the workforce that is represented by a union is higher in Philadelphia than in most cities and areas of the country. So when workers express interest in organizing in Philadelphia they get a lot of support. Other unions might turn out members for their rallies, pressure the company to not oppose the organizing drive and offer other aid and assistance.

The starting wage at the Philadelphia Whole Foods store is US$16 an hour. Is that considered low when the city’s minimum wage is just $7.25 an hour?

The minimum wage in Philadelphia is $7.25 because that is the federal minimum wage. States can institute a higher minimum wage if they choose to, but Pennsylvania is one of the few Northeast states that hasn’t adopted a minimum wage higher than the federal minimum. The minimum wages in New Jersey, New York and Massachusetts, for example, are $15 or above.

But the minimum wage in Pennsylvania is almost irrelevant because of today’s labor market. Unemployment is low, and many employers have to offer significantly more than the minimum wage to get workers.

And the minimum wage is supposed to be a starting wage for workers with little experience or seniority. What workers want is a living wage. According to the MIT Living Wage Calculator, a single person in Philadelphia needs to earn around $24 per hour to cover the basic costs of living. And Whole Foods is a profitable business. It’s part of Amazon, one of the most profitable, largest companies in the world. I think workers at these companies believe that they play an important role in generating those profits because of the work they do. And they think they should get a fair share of those profits.

How might the Whole Foods workers expect the company to fight back?

When employees win an organizing election as the Whole Food workers have, they have won a battle but not the war. The purpose of forming a union is to improve wages and benefits and working conditions, and you do that by negotiating a contract with the company. That is the next step in the process. But the law only requires employers to bargain with employees – to meet at reasonable times and exchange proposals. It doesn’t compel them to agree to anything.

The typical strategy of companies that aggressively oppose their workers having a union is to drag their feet in bargaining and not sign a contract. That is technically illegal, but labor law in the U.S. is relatively weak, and with good legal advice you can drag out bargaining for a very long time.

We’ve seen this with the Starbucks campaign. The first Starbucks store unionized in 2021. Over 540 stores have organized since then. And Starbucks workers at those stores still do not have a contract.

Could the new Trump administration have any impact on how this plays out in Philly?

The fact that the Trump administration has taken over gives companies more confidence that the standard delay strategy will work.

On Jan. 28, 2025, President Donald Trump fired Jennifer Abruzzo, the general counsel of the NLRB. The general counsel is the official at the board who basically enforces the National Labor Relations Act. Abruzzo was very aggressive in holding employers accountable if they violated the act and in protecting the rights of workers who tried to organize.

Trump’s approach to labor law in his first four years in office was at the other extreme. He appointed as general counsel Peter Robb, who was seen as far less aggressive in protecting workers’ rights and his interpretations of the law were much more pro-business.

Under the Biden administration, if a company was coming to the bargaining table month after month and not agreeing to anything, the NLRB would eventually step in and cite the employer for not bargaining in good faith. The NLRB could find the employer guilty of unfair labor practices and genuinely put pressure on it to bargain a contract.

Based on the board’s actions during the first Trump administration, the board in the next few years will be more likely to allow companies to delay and delay in reaching a contract.

What leverage do the Whole Foods employees have?

They can go on strike. But Amazon has the resources to put up with a strike at one Whole Foods store forever.

Other Whole Foods stores may be considering union drives. The more stores that organize, the more momentum the Philadelphia store will have. But for now, these workers in Philly are going to have their work cut out for them.

That said, they won’t be alone. The Whole Foods workers organized with the UFCW Local 1776, which is basically a statewide union that’s been around for decades. It has a lot of resources and experienced and knowledgeable leaders, plus the resources of the national UFCW. So it’s going to lean into this fight, and these workers will also have a lot of support from the rest of the labor community in Philadelphia.

Earlier this month, three Congressional representatives from Pennsylvania wrote a letter to Jason Buechel, the Whole Foods CEO, and to Jeff Bezos, the Amazon founder, that expressed their concerns about efforts to suppress the union drive. Is that support typical?

It’s not unusual. But there is no legal basis for elected officials to intervene in a labor-management dispute. I’d put that under the heading of community support.

You have a lot of progressive elected officials in Philadelphia who are supportive of unions, and that’s true in Pennsylvania right up to the governor.

Understanding paranormal beliefs and conspiracy theories isn’t just about misinformation – this course unpacks the history

Published

on

Uncommon Courses is an occasional series from The Conversation U.S. highlighting unconventional approaches to teaching.

Title of course:

“Investigating the Paranormal”

What prompted the idea for the course?

My training and professional work have been in Mesoamerican archaeology, but I’ve had a lifelong fascination with paranormal concepts. In fact, I considered studying the UFO community for my doctoral research in cultural anthropology.

I eventually fused these two interests in my book “Spooky Archaeology: Myth and the Science of the Past,” which examines why archaeology shows up so much in ideas about the mysterious and weird. Most people are familiar with pop culture characters like Indiana Jones seeking magical artifacts. Perhaps less immediately obvious is just how common archaeological topics are in paranormal and conspiracy culture.

The popularity of paranormal ideas – from television shows and thousands of podcasts to UFOs on the front page of The New York Times and in government investigations – made it clear that a course on paranormal culture would be an excellent way for students to get a taste of social science research.

What does the course explore?

The material begins with premodern ideas of magic, myth and metaphysics. The narrative that “Western” societies tell of the development of the modern world is that the Enlightenment cast off supernatural thinking in favor of science. The historical reality, however, is not so simple.

As science based on observation of material evidence emerged in the 17th through 19th centuries, so did a paranormal worldview: theories about a nonmaterial or hidden reality beyond the mundane, from monsters to psychic powers. Some of these ideas were tied to older religious notions of the sacred or strange but not divine phenomena. Others were new – particularly those suggesting the hidden existence of prehistoric extinct creatures or lost cities.

In either case, the key element was that proponents of these ideas often tried to support their existence with the kind of evidence used in science, though their “proofs” fell short of scientific standards. In other words, the paranormal is in conflict with the knowledge and worldview of modernity but also attempts to use the concepts of modernity to oppose it.

The class examines how this tension produced 20th century “-ologies” like parapsychology, which examines evidence for consciousness beyond matter, and cryptozoology, which searches the ends of the Earth for creatures tied to the mythic past. We also learn about UFOlogy, whose proponents have collected alleged contacts with technology and beings from beyond this world ever since the Cold War, as great earthly powers filled the skies with secretive hi-tech aircraft and spaceships.

As the class concludes, we examine how the “-ologies” declined after the Cold War, alongside the cultural capital of science, whose height of public respect was in the mid-20th century. Since then, proving the existence of paranormal things to institutional scientists has become less important in paranormal communities than promoting them to a broader public.

Why is this course relevant now?

Beyond public interest in paranormal topics, the paranormal is entwined with sociocultural forces that have dramatically increased the role of conspiracy rhetoric in the United States and elsewhere. At their core, both types of belief claim to have figured out some kind of supposedly hidden knowledge.

Furthermore, the conspiracy theories that are now commonplace in American political discourse are more rooted in paranormal ideas than in previous decades. Conspiracy theories about the JFK assassination or even 9/11 were still largely within the materialist realm. People argued that “the truth” had been covered up, but their arguments did not rely on metaphysical ideas. Today, major conspiracy theories involve secret cabals, mystical symbols and code words, demonic forces and extraterrestrial entities.

What’s a critical lesson from the course?

Evidence must be interrogated on its own, regardless of whether it fits your perspective. I find time and again that students have a hard time approaching evidence without bias, whether that bias is conscious or not: “knowing” that something must be true, or must be absurd.

One person apparently makes a death bed confession of faking a famous Loch Ness Monster photo, pleasing skeptics. Another claims to have seen a Bigfoot at close range, pleasing believers. Without further evidence, both are stories: no more, no less.

The issue isn’t to draw an equivalence between the bigger concepts. Not all narratives are equally well-founded. But students learn how to collect evidence, rather than simply rely on their gut sense of what is plausible or not.

What will the course prepare students to do?

This course is meant to help students discern useful and reliable information about claims and events, separating them from irrelevant or inaccurate narratives or sources. The goal is not just “critical thinking” aimed at combating disinformation, though that is part of what they should learn. Students practice evaluating evidence but also develop an approach for analyzing and understanding phenomena behind it: how factors like history, culture and institutions of authority, such as science and government, shape what people trust and what they believe.
