A handheld sensor and innovative technique developed by Texas A&M AgriLife Research scientists could one day offer a noninvasive alternative to food diaries and blood tests when monitoring diet and health.
Using a light-based device, researchers demonstrated that diet, biological age, sex and select nutrient deficiencies could be detected through the skin of live animal models with up to 90% accuracy. The findings, published in Analytical Chemistry, signal a breakthrough in noninvasive health monitoring, including the potential for wearable sensors to provide real-time nutritional and metabolic information.
The researchers believe the technology could help monitor for emerging health concerns and advance personalized dietary recommendations, a key focus of the Texas A&M AgriLife Institute for Advancing Health through Agriculture, IHA.
“Right now, dietary assessments mostly rely on self-reporting, which is often inaccurate,” said Dmitry Kurouski, Ph.D., IHA member and associate professor in the Texas A&M College of Agriculture and Life Sciences Department of Biochemistry and Biophysics. “But with this technology the size of a keychain, we can look directly at how diet changes the body and learn what is and isn’t working at the individual level.”
Diet detection with 90% accuracy
The collaborative project was conducted by Isaac Juárez, a doctoral student in Kurouski’s lab. It builds on findings from David Threadgill, Ph.D., University Distinguished Professor and head of the Department of Nutrition. Threadgill previously performed research on the health impacts of common eating styles, revealing significant differences across diet types.
“We primarily focused on trying to understand how individuals respond to different diets,” Threadgill said. “A lot of data suggests that certain diets are healthier than others, but we don’t know how that translates to the individual level.”
Together, the team repeated Threadgill’s experiment to see if Raman spectroscopy, a light-based sensing technology that Kurouski has used extensively in areas from plant diseases to forensic analysis, could be used to analyze effects of different diets on body composition.
The team fed live animal models one of six common diets, such as vegan, ketogenic and Mediterranean diets, then scanned their skin with Raman spectroscopy to generate a biochemical pattern. The scans identified distinct chemical signatures of key biomolecules, particularly lipids and collagen, linked to each dietary pattern present in the skin.
The result: they found they could distinguish diet type with nearly 90% accuracy.
“For biological systems, anything above 80% is strong,” Kurouski said. “Hitting 90% means this tool could seriously guide nutrition decisions.”
A window into age and nutrient levels
Beyond diet, the scans also revealed age, which they found had a clear relationship to certain chemical markers in the skin, particularly collagen levels.
In further analysis of the scans, the researchers were able to detect folate deficiencies. They  collaborated with Michael Polymenis, Ph.D., professor and associate head of graduate programs in the biochemistry department, and Heidi Blank, Ph.D., research scientist, who have extensively explored the impact of folate on metabolism.
“Folate deficiency is linked to birth defects and poor metabolic outcomes, but it’s hard to detect early,” Polymenis said. “Easy access to information on nutrient levels could help guide dietary interventions even before symptoms begin, especially as nutrient needs shift with age.”
Wearables on the horizon
While the current device is handheld, the researchers believe the technology could be miniaturized further and potentially incorporated into wearable technology. Eventually, such sensors could continuously monitor diet and nutrient levels, empowering users with immediate feedback on nutritional status and patterns.
As chronic diseases like obesity and diabetes continue to rise, they hope the technology could offer a proactive tool for improving public health and preventing nutrition-related health conditions.
“This is the beginning of a very exciting journey,” Kurouski said. “Diet and nutrition are critical to overall health and wellbeing. With this technology, we’re essentially able to read metabolism in real time, and someday soon, people might be able to carry this insight in their daily lives.”

Texas beekeepers lost 61% of their honey bee colonies — nearly 60,000 hives over the past year, according to the most recent statewide survey of more than 400 beekeepers.
This was one of the steepest declines in beehives ever recorded in Texas, said Garett Slater, Ph.D., Texas A&M AgriLife Extension Service honey bee specialist and assistant professor in the Texas A&M College of Agriculture and Life Sciences Department of Entomology based at the Texas A&M AgriLife Research and Extension Center at Overton.
“This isn’t just a beekeeping problem, it’s an agriculture and food security challenge,” Slater said. “When we lose bees at this scale, the ripple effects touch every Texan, from farm to table.”
Strategies and solutions-oriented webinar
Recognizing the urgency, AgriLife Extension hosted a free webinar for Texas beekeepers, growers, educators and the public — What’s Happening to Our Bees? Exploring Honey Bee Declines — at 6 p.m. Aug. 29.
Slater explained the statewide survey data and explore possible solutions. The session will blend scientific findings with practical strategies to strengthen colony survival and pollinator resilience.
AgriLife Extension aids in U.S. Beekeeping Survey
AgriLife Extension’s apiculture program worked closely with the Apiary Inspectors of America and Auburn University to review and refine this year’s survey, ensuring it captures critical data on colony losses, management practices and challenges facing beekeepers.
Bees pollinate one-third of the food we eat, including high-value Texas crops like melons, berries, nuts and vegetables. A sustained decline in pollinator health could upend agricultural productivity, rural economies and ecosystem balance, Slater said.
About the webinar
Slater explained the colony loss data, highlight where declines have been most severe and how trends vary across Texas. He addressed the complex factors driving these losses, from parasitic varroa mites and problems with queen performance to other stressors like nutrition and pesticides.
A recent study by the U.S. Department of Agriculture Agricultural Research Service was discussed, which reveals an increased varroa mite resistance to the commonly used treatment amitraz, along with the rise of new viral threats.
The session provided research updates on efforts to breed virus- and mite-resistant bees, an approach aimed at reducing dependence on broad-spectrum chemical treatments and building long-term colony resilience. “Part of the solution is combining cutting-edge research with widespread public engagement,” Slater said. “By equipping beekeepers and growers with data-driven tools and resilient bee genetics, we can safeguard pollinators for the next generation.”

(09/09/2025)– It is with great pleasure that Southern New Hampshire University (SNHU) congratulates the following students on being named to the Summer 2025 President’s List. The summer terms run from May to August.
Norma Lopez of Devine, Oscar Ramirez-Hurtado of Hondo, Leo DeFelippis of Mico, and Wanda Jackson and Kayla Vasquez of Castroville.

(09/09/2025)– Peyton Ross of Mico (78056) has been named to Southern New Hampshire University’s Summer 2025 Dean’s List. The summer terms run from May to August.

A while back Bo and Wendy Maxwell approached me about doing a painting for them. They wanted this painting to depict old/time Devine as Bo would imagine it in the 1800s. His vision was the young town nestled down in the valley with the train passing through. He wanted bluebonnets, oak trees, a horseman, a road runner and a rattlesnake, (which I almost refused to do), a house and barn, children playing in the lane, a farmhouse and cattle in the distance, and, of course, the hill country on the horizon. I can do that. But wait. This is no ordinary painting on canvas. This is going to be a mural painted on the Maxwell‘s dining room wall! This is going to be a 14 feet wide and 5 feet tall mural painted on site! Well, this is a new venture, but of course I can do it! 
So, when the time came around in February of this year, I gathered up my materials – paint, turpentine, brushes, acrylic paint for the base and headed to Devine. For the next six weeks, I showed up two or three times a week for a 3 to 4 hour afternoon painting session. 
It didn’t take long for Bo and Wendy to learn that I loved Big Red and chips, especially Cheetos. So, every time I showed up, they brought out the refreshments. 
Day One, with the scaffolding in place, I climbed up so I could reach the ceiling! The wall was painted dark maroon, a 14’ wide and 8’ tall maroon wall. Bo had planned to put up a rustic wooden siding along the bottom 3’, so he had taped it off. Remaining was the 14’ X 5’ wall that I had to prime with acrylic to neutralize the maroon! 
The scenario of me on the scaffolding lasted for weeks. But, eventually I painted my way down to ground level! 
On occasion Bo would make suggestions. It’s always good to have a fresh set of eyes. But the coolest thing about this project is how special Wendy and Bo Maxwell treated me and that, regardless of whether it’s true or not, they think the painting is wonderful. I recently asked Wendy if they were tired of looking at it yet. She assured me that they still enjoy it, and I certainly hope so because it’s there for posterity.

McKinney, TX — After Governor Greg Abbott and Brooke Rollins’ press conference on the growing threat of the New World Screwworm, Republican Agriculture Commissioner candidate Nate Sheets released the following statement:
“The New World Screwworm is not just another ag issue—it’s an existential threat to our cattle industry, our rural economy, and the price of beef for Texas families,” said Sheets. “Every day of delay risks billions in losses, permanent damage to ranching operations, and devastation for small producers. Texas needs an Agriculture Commissioner who will act the moment a threat emerges—not weeks or months later after political pressure mounts.”
The New World Screwworm, a flesh-eating parasite once eradicated in the U.S., was detected in early July just 370 miles from Texas. Experts warn it could spread rapidly if not stopped, putting every livestock sector at risk and driving up grocery prices nationwide.
Today’s plan from Abbott and Rollins included five major steps:
Building a $750 million domestic sterile fly production facility in Edinburg to triple output and end reliance on Panama and Mexico for supply.
Investing $100 million in new technologies like novel traps, lures, and modular fly units to accelerate response.
Expanding border surveillance by increasing mounted patrol “tick riders” and the USDA Beagle Brigade.
Unprecedented coordination with Mexico to halt animal movement in infected zones and improve surveillance south of the border.
Cross-agency federal action with FDA, USDA, DOE, and EPA to fast-track treatments and innovations.
“I applaud Governor Abbott and Brooke Rollins for taking swift action on this critical threat and look forward to working with them as Texas’ next Agriculture Commissioner to keep our herds safe and our cattle industry strong,” Sheets said.
