A new University of Houston study of hemp microbes can potentially assist scientists in creating special mixtures of microbes to make hemp plants produce more CBD or have better-quality fibers.

The study, led by Abdul Latif Khan, an assistant professor of biotechnology at the Cullen College of Engineering Technology Division, was published in the journal Scientific Reports from the Nature Publishing Group. The team also included Venkatesh Balan, UH associate professor of biotechnology at the Cullen College of Engineering Technology Division; Aruna Weerasooriya, professor of medicinal plants at Prairie View A&M University; and Ram Ray, professor of agronomy at Prairie View A&M University.

The study examined microbiomes living in and around the roots (rhizosphere) and on the leaves (phyllosphere) of four types of hemp plants. The team at UH compared how these microorganisms differ between hemp grown for fiber and hemp grown for CBD production.

“In hemp, the microbiome is important in terms of optimizing the production of CBD and enhancing the quality of fiber,” Khan said in a news release. “This work explains how different genotypes of hemp harbor microbial communities to live inside and contribute to such processes. We showed how different types of hemp plants have their own special groups of tiny living microbes that help the plants grow and stay healthy.”

The study indicates that hemp cultivation can be improved by better understanding these distinct microbial communities, which impact growth, nutrient absorption, stress resilience, synthesis and more. This could help decrease the need for chemical inputs and allow growers to use more sustainable agricultural practices.

“Understanding these microorganisms can also lead to more sustainable farming methods, using nature to boost plant growth instead of relying heavily on chemicals,” Ahmad, the paper’s first author and doctoral student of Khan’s, said the news release.

Other findings in the study included higher fungal diversity in leaves and stems, higher bacterial diversity in roots and soil, and differing microbiome diversity. According to UH, CBD-rich varieties are currently in high demand for pharmaceutical products, and fiber-rich varieties are used in industrial applications like textiles.

Houston urban agricultural nonprofit gears up for opening of new farm in Second Ward

GROWING FOR GOOD

Small Places, a Houston-based urban agricultural nonprofit, is looking forward to putting down roots beyond the fresh vegetables they grow in the East End.

After securing a 40-year land agreement with Harris County, the organization, which provides produce to families facing food insecurity in the Second Ward, is expecting to open their new farm in February 2025. Small Places’ founders hope the 1.5 acres of land named Finca Tres Robles, located at 5715 Canal Street, will be the beginning of Houston’s urban farming movement.

Founded in 2014 by brothers Daniel, Mark, and Thomas Garcia-Prats, Small Places was born out of the latter brother’s desire to work on an organic farm in his hometown of Houston. After farming in Maine, Iowa, and Nicaragua, Thomas had hoped to manage an urban farm but was unable to find a place. He then roped his brothers, who had no agricultural background at the time, into creating one.

“I joke that my journey in agriculture started the day we started out there. We didn’t grow up gardening or farming or anything of the sort,” says Daniel, Small Places’ director of operations. “It was a big learning curve, but how we approached it to our benefit was through our diverse set of backgrounds.”

Small Places began their need-based produce distribution programs through a partnership with nearby pre-school, Ninfa Lorenzo Early Childhood Center, providing food insecure families with fresh produce and later cooking lessons in 2017. When COVID-19 hit Houston in 2020, Daniel says Small Places pivoted towards becoming a redistribution center for their farming contacts who needed to offload produce as restaurants shut down, selling their crops through the organization. Their neighborhood produce program was then born, providing free boxes of produce to nearly 200 families in the East End at the pandemic’s peak.

“We found ourselves in the middle of two communities who were in need, one being people in our community who were losing jobs and were in need of food as well as our farming connections who were losing restaurant accounts,” Daniel explains.

Small Places currently assists 65 families living predominantly within two miles of their original location and they recently restarted their programming with Ninfa Lorenzo Early Childhood Center, and accepts Supplemental Nutrition Assistance Program benefits (SNAP) at their farm stand. Daniel says once Finca Tres Robles opens, Small Places plans to bring back cooking classes and educational seminars on healthy eating for which his brother Mark, a former teacher, created the original curriculum. The farm will also have a grocery store stocked with Finca Tres Robles' produce and eventually food staples from local vendors.

“Being social and preparing a meal can be fun, interesting, and delicious. Being able to pull all of that into a program was really important for us,” Daniel explains.

Farming successfully in the middle of Houston for their subsidized programs and produce market requires Small Places’ team to be strategic in their operations. Using his background in engineering and manufacturing, Daniel says they’ve closely monitored trends in which crops perform the best in Houston’s varied, humid climate over the past decade.

They also follow Thomas’s philosophy of allowing nature to work for them, planting crops at times when specific pests are minimal or integrating natural predators into their environment. And lots of composting. Daniel says they accept compostable materials from community members, before burying the raw organic matter in the earth in between their plant beds, allowing it to mature, then later using it to nourish their crops. Daniel says he and his co-founders hope to see more community-focused, sustainable operations like theirs spring up across Houston.

“Small Places is about hopefully more than one farm and really trying to turn urban agriculture and a farm like ours from a novel thing into something that’s just a part of communities and the fabric of Houston for generations to come,” Daniel says.

Houston area drone company on track to revolutionize the agriculture industry

in-flight innovation

Renowned American inventor Thomas Edison once said, "There's a way to do it better, find it."

That timeless adage has been the spark that has ignited countless technological advances over the years and Hylio is no different, applying it to its own mission to disrupt the agricultural technology space.

With rampant systemic inefficiencies with current crop spraying solutions negatively affecting farm economics, Hylio developed its AgroDrone, a precision crop spraying drone system that is revolutionizing ag-tech.

"Our company started about five years ago, when we were delivering in Central America and noticed the way people were doing spraying was extremely inefficient," says Arthur Erickson, CEO and co-founder of Hylio. "They were doing it either by hand or by plane or helicopter. If you are doing it by hand, you are doing it extremely slow and very inaccurate. If you're doing it by plane or helicopter, you're doing it faster, but you're extremely inaccurate."

In most cases, when farmers use traditional crop spraying methods such as helicopter or plane, up 90 percent of the fertilizer or pesticides miss their intended targets or float away.

However, AgroDrone, which was recently accepted into the Capital Factory accelerator, provides for a very precise method of applying those chemicals with its intuitive planning system, which monitors and controls the spray volumes using pre-existing map files or polygons.

"For the past year, we've been our own first customer," says Erickson. "We've used the technology in El Salvador, Honduras and Guatemala on 40,000 acres. We learned the product and what made it more efficient by using it in the field 10 hours a day. We built this from the ground up using it as a farmer would. We worked out all the bugs, optimized it and made it reliable, so when farmers are out there in the mud or in the rain, it still works."

The drone's flight software allows it to be completely turnkey. The electron-based application can be run on any cross platform and gives pilots control over the drone at all times.

Additionally, the redundant critical flight system ensures stable flight.

"Our software was made completely in house," says Erickson. "Like a Google map interface, you can set up your own pre-loaded missions, in different polygon shapes, draw them yourself or import polygon files and generate missions for the drone to fly."

Because of the radar altimeters fitted on the drones, farmers are able to reduce the amount of chemicals they use because the drones maintain optimal height over crops at all times, which minimizes drift and maximizes application quality.

"If you talk to any farmer that has 400 acres of corn, for example, and they want to get it sprayed, it would cost them maybe $400 times 10 for labor times 10 for chemicals, so about $8000," says Erickson. "The problem is they're providing a brute force solution to a problem that is very simple to solve with a drone.

"If they've got weeds on their 400 acres, and the weeds are only on one or two acres, little spots in the field, they just want to eliminate those spots, so they don't need to pay someone to spray their entire field, so they're saving the chemical cost per acre is $10 bucks. So if they run our drone for 10 minutes, they're literally saving $7,000 or more."

The innovators behind Hylio started the company because they were passionate about drones, but saw that the crop spraying system for farmers was broken and inefficient, so they sought to make the process better and more sustainable.

"Farmers are responsible for how we eat, how everyone eats," says Erickson. "The current technologies used in agriculture is outdated and not very cost effective. We looked at the farm economics and wanted to help develop viable solutions. Every farmer has to battle weeds; it is universal. All crop and weeds are different, but it is the same concept. The more you control the weeds, the more money you make at the end of the year. A farmer could lose 20 percent or more of their crops if they do not control their weeds properly. Despite the inefficiencies and razor thin margins, farmers still use helicopters and planes because they have to kill those weeds.

"There's a better way to do it with drones and it comes at a fraction of the price."

The AgroDrone starts at $19,300 and is delivered to the farmer fully tested and assembled. The package includes four pairs of 30,000 mAh 22V LiPo batteries, charging equipment, one handheld GPS tracker unit and access to the Hylio AgroSol Mission Control Software.

The software, which was designed by farmers for farmers, requires a recurring monthly fee that ranges from $100 to $500 depending on the level.

Hylio also provides the central device that can control multiple drones at the same time and service hundreds of acres per day.

"The people that are doing the weed control spraying for farmers literally won't come out because it's not worth their time to just come out and spray one or two acres," says Erickson. "So even if a farmer has a problem that they know is only on one or two acres, they have to spray the whole thing, because they market will only allow people to spray the entire amount. They cannot come out and afford to spray one or two acres. However, if you buy a drone, you can do it yourself with the click of a button. Farmers are saving literally $10,000 per application depending on how big their crop is."

According to the US Department of Agriculture, American farmers received $11.5 billion in subsidies in 2017. That number will be drastically higher in 2019 to offset the market losses farmers will see due to President Donald Trump's trade war with China.

With profits in continual decline, Hylio's mission to improve margins for farmers continues.

"Farming is heavily subsidized now," says Erickson. "None of them are making money, so they desperately need something to increase their bottom lines. We are here to make farmers' lives better and help them feed us better. It's a win win."

Houston residents rank economy as biggest problem, new Kinder survey shows

by the numbers

The region’s economy tops the list of concerns of Houston-area residents surveyed by Rice University’s Kinder Institute for Urban Research.

Respondents in the Kinder Houston Area Survey, which questioned nearly 9,000 residents of Harris, Fort Bend and Montgomery counties, cite the regional economy as the area’s “biggest problem.”

Shrinking confidence in job opportunities and growing household financial pressures fueled the grim economic outlook:

  • The share of residents rating job prospects as “good” or “excellent” fell by more than 25 percentage points, the sharpest single-year decline since the 1980s.
  • Seventy-nine percent of those earning less than $25,000 said they’d be unable to cover an unplanned $400 expense. That was up from 72 percent last year. In the $50,000-to-$99,999 category, the figure was 39 percent, up from 30 percent last year.
  • More than 20 percent of residents said their financial status was worse than it was 12 months earlier.

“These challenges were particularly notable among lower- and middle-earning households,” according to a report about the survey.

Dan Potter, co-director of the institute’s Houston Population Research Center, says the annual survey “provides community leaders and the public with a map of where we’ve been on key issues, where we are now, and what’s of looming importance. It allows everyone to work together toward a better future for our city and our region.”

Houston-based Oxy officially announces CEO transition, names successor

Team Transition

Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

Rice Brain Institute awards seed grants for dementia, Alzheimer’s research

brain trust

The recently established Rice Brain Institute awarded 12 seed grants last month to support research on dementia, Alzheimer’s disease, Parkinson’s disease and other neurological disorders.

The grants are part of the Rice DPRIT Seed Grant Program, which aims to help faculty members generate preliminary data, test and teams that would be supported under the Dementia Prevention and Research Institute of Texas.

The DPRIT was approved last year to provide $3 billion in state funding over a 10-year span for research on dementia prevention and other neurological conditions. It will be modeled after the Cancer Prevention and Research Institute of Texas (CPRIT), which has awarded nearly $4 billion in grants since 2008.

“DPRIT is a historic initiative with transformative impact potential and at Rice we are very well equipped to contribute to its mission and help make Texas a leader in brain health and innovation,” Behnaam Aazhang, a Rice professor of electrical and computer engineering and director of the Neuroengineering Initiative and the RBI, said in a news release.

The Rice DPRIT Seed Grant Program is supported by the RBI and the Educational and Research Initiative for Collaborative Health (ENRICH) office at Rice. Most of the funding came from Rice's Office of Research, with a contribution from Rice's Amyloid Mechanism and Disease Center, which also launched last year.

A number of the teams include collaborators from Houston's Texas Medical Center, including Baylor College of Medicine, University of Texas Medical Branch and the McGovern Medical School at UTHealth Houston.

The 12 teams are:

  • Keya Ghonasgi, assistant professor of mechanical engineering at Rice. Ghonasgi's research addresses the high risk of falls among people with different types of dementia and aims to develop a personalized, home-based fall-prevention approach using textile-integrated wearable sensors.
  • Luz Garcini, associate professor of psychological sciences at Rice, and Hannah Ballard, associate director of community and public health at the Kinder Institute for Urban Research at Rice. Garcini and Ballard's research looks at barriers and facilitators to early detection of Alzheimer’s disease in diverse, medically underserved urban communities and focuses on populations that experience late diagnosis, including Hispanic/Latino groups.
  • Lei Li, assistant professor of electrical and computer engineering at Rice, and Pablo Valdes, assistant professor of neurosurgery at UTMB. Li and Valdes' project develops a noninvasive, bedside imaging approach to monitor brain blood flow and oxygenation in patients recovering from stroke or brain surgery using photoacoustic imaging through a specialized transparent skull implant.
  • Cameron Glasscock, assistant professor of biosciences at Rice. Glasscock's project addresses repeat expansion disorders, such as Huntington’s disease and myotonic dystrophy, and focuses on stopping DNA instability before repeats reach a disease-causing threshold.
  • Raudel Avila, assistant professor of mechanical engineering at Rice. Avila's project focuses on everyday health factors such as nutrition, hydration and brain blood flow and how they influence brain aging long before symptoms of dementia appear.
  • Isaac Hilton, associate professor of bioengineering at Rice, and Laura Lavery, assistant professor of biosciences at Rice. Hilton and Lavery's project uses precise CRISPR-based gene regulation to target multiple genetic drivers of neuronal damage in Alzheimer’s.
  • Quanbing Mou, assistant professor of chemistry at Rice, and Qing-Long Miao, assistant professor of neurology at Baylor College of Medicine. Mou and Miao's project aims to develop a gene-regulation therapy for childhood absence epilepsy by restoring activity of the CACNA1A gene.
  • Momona Yamagami, assistant professor of electrical and computer engineering at Rice, and Christopher Fagundes, professor of psychological sciences at Rice. Yamagami and Fagundes' project addresses the physical and mental health challenges faced by spouses caring for partners with Alzheimer’s disease and related dementias and aims to develop algorithms to determine the optimal timing and frequency of supportive text messages.
  • Han Xiao, professor of chemistry at Rice. Xiao's project aims to improve the delivery of antibody therapies to the brain using a noninvasive, light-based approach that temporarily opens the blood–brain barrier.
  • Lan Luan, associate professor of electrical and computer engineering at Rice. Luan's project investigates how tiny blood-vessel injuries in the brain, known as microinfarcts, contribute to dementia.
  • Natasha Kirienko, associate professor of biosciences at Rice. Kirienko's project targets a shared cause of neurodegeneration, impaired mitochondrial cleanup, and aims to identify an existing antidepressant that could be repurposed to protect neurons in diseases like Alzheimer’s and Parkinson’s.
  • Harini Iyer, assistant professor of biosciences at Rice. Iyer's project will observe zebrafish to investigate how the brain’s primary immune cells become improperly activated in neurological disorders, leading to the loss of healthy neurons and cognitive impairment.

The RBI also named the first four projects to receive research awards through the Rice and TMC Neuro Collaboration Seed Grant Program in January. Read more about those projects here.
