Bioengineers at Rice University have developed a “new construction kit” for building custom sense-and-respond circuits in human cells, representing a major breakthrough in the field of synthetic biology, which could "revolutionize" autoimmune disease and cancer therapeutics.

In a study published in the journal Science, the team focused on phosphorylation, a cellular process in the body in which a phosphate group is added to a protein, signaling a response. In multicellular organisms, phosphorylation-based signaling can involve a multistage, or a cascading-like effect. Rice’s team set out to show that each cycle in a cascade can be treated as an elementary unit, meaning that they can be reassembled in new configurations to form entirely novel pathways linking cellular inputs and outputs.

Previous research on using phosphorylation-based signaling for therapeutic purposes has focused on re-engineering pathways.

“This opens up the signaling circuit design space dramatically,” Caleb Bashor, assistant professor of bioengineering and biosciences and corresponding author on the study, said in a news release. “It turns out, phosphorylation cycles are not just interconnected but interconnectable … Our design strategy enabled us to engineer synthetic phosphorylation circuits that are not only highly tunable but that can also function in parallel with cells’ own processes without impacting their viability or growth rate.”

Bashor is the deputy director for the Rice Synthetic Biology Institute, which launched last year.

The Rice lab's sense-and-respond cellular circuit design is also innovative because phosphorylation occurs rapidly. Thus, the new circuits could potentially be programmed to respond to physiological events in minutes, compared to other methods, which take hours to activate.

Rice’s team successfully tested the circuits for sensitivity and their ability to respond to external signals, such as inflammatory issues. The researchers then used the framework to engineer a cellular circuit that can detect certain factors, control autoimmune flare-ups and reduce immunotherapy-associated toxicity.

“This work brings us a whole lot closer to being able to build ‘smart cells’ that can detect signs of disease and immediately release customizable treatments in response,” Xiaoyu Yang, a graduate student in the Systems, Synthetic and Physical Biology Ph.D. program at Rice who is the lead author on the study, said in a news release.

Ajo-Franklin, a professor of biosciences, bioengineering, chemical and biomolecular engineering and a Cancer Prevention and Research Institute of Texas Scholar, added “the Bashor lab’s work vaults us forward to a new frontier — controlling mammalian cells’ immediate response to change.”

Pioneering Houston biotech startup expands to Brazil for next phase

On the Move

Houston biotech company Cemvita has expanded into Brazil. The company officially established a new subsidiary in the country under the same name.

According to an announcement made earlier this month, the expansion aims to capitalize on Brazil’s progressive regulatory framework, including Brazil’s Fuel of the Future Law, which was enacted in 2024. The company said the expansion also aims to coincide with the 2025 COP30, the UN’s climate change conference, which will be hosted in Brazil in November.

Cemvita utilizes synthetic biology to transform carbon emissions into valuable bio-based chemicals.

“For decades Brazil has pioneered the bioeconomy, and now the time has come to create the future of the circular bioeconomy,” Moji Karimi, CEO of Cemvita, said in a news release. “Our vision is to combine the innovation Cemvita is known for with Brazil’s expertise and resources to create an ecosystem where waste becomes opportunity and sustainability drives growth. By joining forces with Brazilian partners, Cemvita aims to build on Brazil’s storied history in the bioeconomy while laying the groundwork for a circular and sustainable future.”

The Fuel of the Future Law mandates an increase in the biodiesel content of diesel fuel, starting from 15 percent in March and increasing to 20 percent by 2030. It also requires the adoption of Sustainable Aviation Fuel (SAF) and for domestic flights to reduce greenhouse gas emissions by 1 percent starting in 2027, growing to 10 percent reduction by 2037.

Cemvita agreed to a 20-year contract that specified it would supply up to 50 million gallons of SAF annually to United Airlines in 2023.

"This is all made possible by our innovative technology, which transforms carbon waste into value,” Marcio Da Silva, VP of Innovation, said in a news release. “Unlike traditional methods, it requires neither a large land footprint nor clean freshwater, ensuring minimal environmental impact. At the same time, it produces high-value green chemicals—such as sustainable oils and biofuels—without competing with the critical resources needed for food production."

In 2024, Cemvita became capable of generating 500 barrels per day of sustainable oil from carbon waste at its first commercial plant. As a result, Cemvita quadrupled output at its Houston plant. The company had originally planned to reach this milestone in 2029.

Houston company's sustainable oil product reaches milestone production capacity 5 years early

overachieving

Houston-based biotech company Cemvita has achieved a key production goal five years ahead of schedule.

Thanks to technology advancements, Cemvita is now capable of generating 500 barrels per day of sustainable oil from carbon waste at its first commercial plant. As a result, Cemvita has quadrupled output at the Houston plant. The company had planned to reach this milestone in 2029.

Cemvita, founded in 2017, says this achievement paves the way for increased production capacity, improved operational efficiency, and an elevated advantage in the sustainable oil market.

“What’s so amazing about synthetic biology is that humans are just scratching the surface of what’s possible,” says Moji Karimi, co-founder and CEO of Cemvita. “Our focus on the first principles has allowed us to design and create new biotech more cheaply and faster than ever before.”

The production achievement follows Cemvita’s recent breakthrough in development of a solvent-free extraction bioprocess.

In 2023, United Airlines agreed to buy up to one billion gallons of sustainable aviation fuel from Cemvita’s first full-scale plant over the course of 20 years.

Cemvita’s investors include the UAV Sustainable Flight Fund, an investment arm of Chicago-based United; Oxy Low Carbon Ventures, an investment arm of Houston-based energy company Occidental Petroleum; and Japanese equipment and machinery manufacturer Mitsubishi Heavy Industries.

Houston health care leaders announce new hub for cancer-fighting bioengineering

team work

Two Houston organizations recently announced a new hub that will focus on developing cell therapies, nanotechnologies, cancer vaccines, artificial intelligence, and molecular imaging.

Rice University and The University of Texas MD Anderson Cancer Center have teamed up to “drive industry growth and advance life-saving technologies” through the newly established Cancer Bioengineering Collaborative, according to a news release announcing the initiative.

The collaboration between the two institutions includes fundamental and translational cancer research, developing new technologies for cancer detection and therapy, and securing external funding in support of further research and training.

Leading the hub will be Rice researcher and Cancer Prevention and Research Institute of Texas (CPRIT) scholar Gang Bao and MD Anderson’s Dr. Jeffrey Molldrem.

“There is tremendous potential in bringing together experts in engineering and cancer as part of this focused, collaborative framework that is truly unique, not only owing to the complementary nature of the respective strengths but also because this is the first formal joint research initiative of its kind between the two institutions,” says Bao, department chair and Foyt Family Professor of Bioengineering, professor of chemistry, materials science and nanoengineering and mechanical engineering, in the release.

The joint effort will also host monthly seminars focused on cancer bioengineering, annual retreats to highlight research and international leaders in cancer and bioengineering, and also a seed grant program to fund research projects in the early stages of development.

“From fundamental discoveries in cancer science, tumor immunology and patient care to innovative engineering advances in drug delivery systems, nanostructures and synthetic biology, there is great potential for enabling cross-disciplinary collaboration to develop new technologies and approaches for detecting, monitoring and treating cancer,” Molldrem, chair of Hematopoietic Biology & Malignancy at MD Anderson, says in the release. “Our goal is to bridge the gap between bioengineering and cancer research to create transformative solutions that significantly improve patient outcomes.”

“At Rice, we have such deep expertise in synthetic biology,” Ajo-Franklin said in the announcement. “Connecting that deep expertise through this institute will lead to better science and more innovation.”

Synthetic biology is a discipline in which "researchers design living systems with new properties to address societal needs," according to Rice, with applications in medicine, manufacturing and environmental sustainability.

The university says that there are currently 18 faculty and more than 100 students and postdoctoral scholars at Rice working in this field within the schools of engineering and natural sciences.

The institute will initially focus on four research themes:

  1. Controlling the biological synthesis and patterning of proteins and cells into living materials that self-replicate and self-repair across a range of length scales
  2. Understanding cells as natural sensors and repurposing them into living therapeutics to detect and treat diseases, maintain health and prevent infections
  3. Developing living electronics to convert biochemical information into information-dense electronic signals in real-time at the cell-material interface
  4. Supporting cross-cutting scholarship aimed at accelerating the Design-Build-Test-Learn cycle and understanding the ethical, legal and social implications of translating these technologies into the public domain.

“Rice University is an amazing place to learn, teach, research and innovate,” Ramamoorthy Ramesh, executive vice president for research, added. “The Rice Synthetic Biology Institute will ensure that our researchers are recognized on the international stage for the life-changing work they are doing in Houston and around the world.”

Last year, Rice also launched the new Center for Human Performance with Houston Methodist inside Rice’s Tudor Fieldhouse. The interdisciplinary space aims to advance the study of exercise physiology, injury prevention, and rehabilitation while serving Rice student-athletes.

The university also unveiled another massive, collaborative space this academic year: The 250,000-square-foot Ralph S. O’Connor Building for Engineering and Science. Click here to read more about the state-of-the-art building.

Investor advocates now is the time to position Houston as a leading biomanufacturing hub

houston innovators podcast episode 178

Houston has all the ingredients to be a successful synthetic biology hub, says Veronica Wu. She believes so strongly in this that she relocated to Houston from Silicon Valley just over a year ago to start a venture capital firm dedicated to the field. Since then, she's doubled down on her passion for Houston leading in biotech — especially when it comes to one uniquely Houston opportunity: biomanufacturing.

While Houston's health care innovation scene is actively deploying synthetic biology applications, Wu points to Houston-based Solugen, a plant-based chemical producer, as an example of what Houston has to offer at-scale industrial biomanufacturing. Houston has the workforce and the physical space available for more of these types of biomanufacturing plants, which have a huge potential to move the needle on reducing carbon emissions.

"This is really fundamental technology that's going to change the paradigm and whole dialogue of how we are making a significant impact in reducing a carbon footprint and improving sustainability," says Wu, founder and managing partner of First Bight Ventures, on the Houston Innovators Podcast.

Several aspects — government funding, corporate interest, advances in technology — have converged to make it an ideal time for synthetic biology innovators and investors, Wu explains on the show, and she has an idea of what Houston needs to secure its spot as a leader in the space: The BioWell.

First introduced at a Houston Tech Rodeo event at the Texas Medical Center's Innovation Factory, The BioWell is a public-private partnership that aims to provide access to pilot and lab space, mentorship and programming, and more support that biomanufacturing innovators critically need.

"The way we envision The BioWell is it will provide a holistic, curated support for startups to be able to get across the Valley of Death," Wu says, explaining that startups transitioning from research and development into commercialization need extra support. The BioWell will provide that, as well as allow more engagement from corporations, investors, and other players.

Now that her plans for The BioWell have been announced, Wu is looking for those who want to be a part of it.

She shares more about her mission and what's next for First Bight Ventures on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Houston's surge in new startups cools since pandemic peak, study shows

by the numbers

Startup activity in the Houston metro area has dipped since its pandemic peak, according to a new study.

Dating back to 2005, the volume of applications to form new businesses in the Houston area hit its highest level in 2021 (151,804). Since then, though, the application volume has fallen, according to the study, conducted by business debt collection agency The Kaplan Group. Here's the breakdown from the last few years:

  • Applications dropped to 130,011 in 2022
  • Climbed to 145,926 in 2023
  • Dropped again to 138,595 in 2024

Looking at the Houston area’s figures another way, the 2024 total surpassed the 2015-19 average by roughly 60 percent to 90 percent, the study shows.

Dallas-Fort Worth has seen similar startup declines (162,312 in 2021 vs. 153,378 in 2024), but the San Antonio metro area recorded higher application volume in 2023 and 2024 (37,412 and 35,798, respectively) than it did in 2021 (34,208).

The story is different in the Austin metro area. Application volume in 2023 and 2024 (53,200 and 59,190, respectively) exceeded the 2021 total (47,106).

The picture for startup activity in Texas’ four major metros deviates from the nationwide picture.

“America’s real viral trend is entrepreneurship,” says The Kaplan Group. “New business formations are reaching an all-time high across the country.”

In the U.S., per-month business formations soared 435 percent from 2004 (89,561) to 2025 (478,805), the study says.

Amid the growth of startup activity, business bankruptcies in the U.S. have plummeted almost 74 percent since 2004, according to The Kaplan Group.

“The country’s business scene has grown both more resilient and more ambitious in the past two decades,” the collection agency says.

Texas is the 4th hardest working state in America, report finds

Ranking It

It's no secret that Texans are hardworking people. To align with the Labor Day holiday, a new WalletHub study asserts that the Lone Star State is one of the five most hardworking states in America for 2025.

The report ranked Texas the fourth most hardworking state this year, indicating that its residents are working harder than ever after the state fell into seventh place in 2024. Texas previously ranked No. 4 in 2019 and 2020, slipped into No. 5 in 2021 and 2022, then continued falling into sixth place in 2023. But now the state is making its way back to the top of the list.

WalletHub's analysts compared all 50 states based on "direct" and "indirect" work factors. The six "direct" work factors included each state's average workweek hours, employment rates, the share of households where no adults work, the share of workers leaving vacation time unused, and other data. The four "indirect" work factors consisted of workers' average commute times, the share of workers with multiple jobs, the annual volunteer hours per resident, and the average leisure time spent per day.

North Dakota landed on top as the most hardworking state in America for 2025 for another year in a row, earning a score of 66.17 points out of a possible 100. For comparison, Texas ranked No. 4 with 57.06 points. Alaska (No. 2), South Dakota (No. 3), and Hawaii (No. 5) round out the top five hardest working states.

Across the study's two main categories, Texas ranked No. 5 in the "direct" work factors ranking, and earned a respectable No. 18 rank for its "indirect" work factors.

Broken down further, Texans have the second-longest average workweek hours in America, and they have the 12th best average commute times. Texans have the 6th lowest amount of average leisure time spent per day, the report also found.

According to the study's findings, many Americans nationwide won't take the chance to not work as hard when presented with the opportunity. A 2024 Sorbet PTO report found 33 percent of Americans' paid time off was left unused in 2023.

"While leaving vacation time on the table may seem strange to some people, there are plenty of reasons why workers choose to do so," the report's author wrote. "Some fear that if they take time off they will look less dedicated to the job than other employees, risking a layoff. Others worry about falling behind on their work or are concerned that the normal workflow will not be able to function without them."

The top 10 hardest working states are:

  • No. 1 – North Dakota
  • No. 2 – Alaska
  • No. 3 – South Dakota
  • No. 4 – Texas
  • No. 5 – Hawaii
  • No. 6 – Virginia
  • No. 7 – New Hampshire
  • No. 8 – Wyoming
  • No. 9 – Maryland
  • No. 10 – Nebraska
