Research looks to transform manure into protein
Last Updated on September 7, 2025 by Daily News Staff
Texas A&M AgriLife Research focuses on environmental impact of turning waste into a resource
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.”

Food Truths
Soul Food Has African Roots—and a Distinct Black American History
Soul food connects African heritage with generations of Black American creativity and community. Here’s why shared roots and a distinct cultural identity both deserve recognition.
Shared ancestry connects the African diaspora. It also makes understanding each community’s food traditions worth the effort.
A debate over who can claim soul food raises a question larger than any social media argument: When does a shared cultural inheritance become a distinct tradition?
People across Africa and the African diaspora have foods that evoke home, family, comfort, and belonging. Recognizing that connection is valuable. But using “soul food” as a general description of comforting food is different from identifying the cuisine historically known by that name.
Soul food is a distinctly African American culinary tradition with African roots, shaped by generations of Black life in the United States. Recognizing its American development does not erase Africa. Recognizing Africa should not erase what Black Americans created.
African Roots, American Development
Enslaved Africans arrived with agricultural knowledge, cooking skills, and food traditions. They adapted those traditions to unfamiliar surroundings and unequal access to food, drawing on available ingredients and encounters with Indigenous and European foodways.
Okra, black-eyed peas, and vegetable-centered cooking offer important connections to African traditions. Corn and cornmeal reflect Indigenous American agriculture. These ingredients and influences became part of an evolving food culture rather than remaining unchanged copies of dishes from another continent. [1]
The distinction is between ancestry and development. A cuisine can descend from older traditions and acquire its own identity through the experiences of the people who preserve and transform it.
More Than a Story About Scraps
Slavery and deprivation belong in this history. Enslaved people supplemented restricted food supplies through gardening and other means, and used small amounts of meat to season vegetables. But telling the entire story as “making something out of scraps” understates their knowledge and creativity.
Black food history also includes seafood work, farming, skilled cooking, and enterprise. The Smithsonian’s account of Black foodways, for example, documents African Americans’ extensive involvement in harvesting, processing, and selling oysters. [2]
These were people with expertise. Their contributions deserve recognition as culinary work and cultural creation.
Why the Name Matters
The food traditions are older than the widespread use of the name “soul food.” The term became prominent during the 1960s, amid movements asserting Black identity and cultural pride. Smithsonian histories describe the soul food movement as celebrating foods that mainstream America had often disparaged. [3]
That context gives the name meaning beyond a meal that tastes good or brings comfort.
For some families, a pot of greens or a pan of cornbread carries memories of relatives, church dinners, holidays, and recipes learned by watching someone cook. Calling those foods “soul food” places them within a particular cultural story.
Southern Roots Traveled
Soul food also developed beyond the South. During the Great Migration, Black Americans carried Southern food traditions into new cities and neighborhoods, preserving familiar dishes while adapting their cooking. Smithsonian programming connects that movement directly to soul food’s development. [4]
That helps explain how a cuisine rooted in the South became part of Black community life across the country.
It also makes geography an imperfect test of authenticity. Soul food cooked in London can still be African American soul food. A cuisine’s cultural origins do not change simply because someone prepares it elsewhere.
Shared Heritage Does Not Mean Identical Cultures
Africa is a continent of many food traditions. The diaspora is similarly diverse. African American, Afro-Caribbean, Afro-Latin American, and Black British identities encompass different histories and relationships to food.
Someone may use “soul food” figuratively to describe a cherished family dish. That emotional use is understandable. The difficulty arises when it becomes a historical claim that all Black cuisines are versions of the same named tradition.
Shared ingredients and ancestry establish connections; they do not make distinct cuisines interchangeable.
A useful conversation would ask which dishes are related, what techniques survived, and how different communities adapted them. That approach gives people more history to appreciate.
Respect Through Recognition
Defending soul food’s African American identity need not become an attack on Africans, Caribbean people, or Black Britons. Equally, celebrating connections across the diaspora should include respect for Black Americans’ particular contributions.
Anyone can cook, enjoy, study, and share soul food. Cultural recognition does not require closing the kitchen door. It requires crediting the people and history behind the cuisine.
Soul food’s African roots and African American identity belong in the same sentence. Both deserve to be remembered.

Where Does Federal Money Go? The Biggest Costs Behind the Budget
Where does federal money go? Part two of our National Debt Explained series examines the biggest expenses in the 2025 budget and how spending connects to government borrowing.
Last Updated on October 13, 2026 by Daily News Staff
The Knowledge | National Debt Explained, Part 2
When discussing debt, ask: Who borrowed the money? That question helps distinguish a family’s finances from the federal budget. Our first episode explained why your credit card balance is separate from the national debt. Now comes the next question: What does the federal government spend money on?
Much of it pays for retirement benefits, health coverage, national defense, public services, and interest on previous borrowing.
Social Security was the largest individual program in fiscal year 2025, costing approximately $1.6 trillion. But combine the major health care programs—including Medicare, Medicaid, and health insurance subsidies—and their spending reached about $1.8 trillion, exceeding Social Security alone. cbo.gov
The figures below cover October 1, 2024, through September 30, 2025.Major expense FY 2025 spending What it supports Social Security About $1.6 trillion Retirement, survivor, and disability benefits Medicare, net $988 billion Health coverage for older adults and certain people with disabilities Net interest $970 billion Cost of servicing publicly held federal debt, after subtracting interest income Discretionary defense $893 billion Military personnel, operations, equipment, and research Medicaid $668 billion Federal contribution toward health coverage and care for eligible people
These are selected expenses, not the entire budget. Medicare spending is shown after premiums and other offsetting receipts. The combined health care total already includes Medicare and Medicaid, so it should not be added to those rows. cbo.gov
The government also supports veterans’ health care, transportation, education, housing assistance, courts, law enforcement, scientific research, disaster response, and environmental protection. Nondefense discretionary spending totaled approximately $980 billion in 2025, covering many of these services. Some funding for these areas falls elsewhere in the budget. cbo.gov
Federal spending falls into three broad groups:
- Mandatory spending: Payments governed by existing eligibility rules and benefit formulas, including Social Security and major health programs.
- Discretionary spending: Funding lawmakers control through appropriations legislation, including most defense spending and many public services.
- Net interest: The expense of servicing publicly held federal debt, minus government interest income. cbo.gov
Interest deserves attention because it pays for borrowing already undertaken. In 2025, net interest exceeded discretionary defense spending. Congressional Budget Office
A program’s cost does not automatically translate into an equal increase in national debt. Taxes and other receipts finance much of federal spending. Social Security and Medicare’s hospital insurance program receive dedicated payroll taxes, while Medicare also collects premiums.
In 2025, federal spending totaled approximately $7 trillion, compared with $5.2 trillion in revenue. The roughly $1.8 trillion shortfall was the deficit, requiring borrowing. Understanding national debt therefore means examining both what government spends and what it collects. cbo.gov

Whose Debt Is the National Debt?
The national debt isn’t Americans’ credit card balances added together. This simple explainer separates federal borrowing from household debt and explains the difference between debt and a deficit.
Last Updated on October 11, 2026 by Daily News Staff
The Knowledge | STM Daily News
When you hear “national debt,” do you picture everyone’s credit card balances added together? The name can create that impression, but the national debt and household debt measure different borrowing.
The U.S. national debt is money the federal government owes. Your personal credit card balance is not included.
Federal debt versus household debt
The Treasury defines national debt as the federal government’s total outstanding borrowing accumulated over the country’s history. Household debt covers borrowing by individuals and families, including mortgages, credit cards, auto loans, and student loans.
|Type of debt |Who borrowed? |Examples |
|————–|————————|————————————————–|
|National debt |Federal government |Outstanding Treasury securities |
|Household debt|Individuals and families|Credit cards, mortgages, auto loans, student loans|
Putting a $500 purchase on your credit card increases your personal balance. It does not add $500 to the national debt.
How does the national debt grow?
When federal spending exceeds tax collections and other revenue, the government runs a budget deficit. Treasury sells securities to borrow money to cover the gap.
Consider a simplified, hypothetical example: the government collects $5 trillion and spends $6 trillion in one year. That leaves a $1 trillion deficit requiring financing.
A deficit measures a shortfall over a period, usually a year. Debt measures outstanding borrowing accumulated over time. Repeated deficits generally increase that debt. Interest on existing borrowing is also a federal expense.
Does paying off your credit card reduce the national debt?
Paying off a card reduces what you owe your lender. It does not directly repay Treasury borrowing. Household debt and government debt can influence the same economy, but they remain separate obligations.
When discussing debt, ask: Who borrowed the money? That one question helps distinguish a family’s finances from the federal budget.
