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.”

3 Houston innovators to know this week

Who's who

A true innovator is someone who's able to look past how something has been done for years — decades even — and be creative enough to find a better way to do it.

From redesigning conventional lab space to seeing a niche opportunity for luxury home rentals, these three innovators to know this week have made strides in changing the game.

Not all labs are created equal — or affordably. Caleb Bashor, a professor at Rice University, along with seven colleagues, created a DIY lab to further research efforts based at the university.

The DIY lab, eVOLVER, comprises three modules: a customizable "smart sleeve" housing and interface for each culture vessel, a fluidic module that controls movement of liquid in and out of each culture vessel, and a modular hardware infrastructure that simplifies high-volume bi-directional data flow by decoupling each parameter into individual microcontrollers.

"The prototype 16-chamber version of eVOLVER described in the new paper cost less than $2,000, cheaper than what a lab might pay for a single continuous culture bioreactor," Bashor says. Read more about the eVOLVER here.

Sébastien Long ended up in Houston by chance, and the city ended up being a great place to take his luxe apartment rental business plan and turn it into a reality. Houston-based Lodgeur is a rental company that takes the convenience of Airbnb and adds in the luxury experience of a hotel.

Long identified stylish apartment complexes and built his business which now has a couple properties downtown that are attractive to a niche market of clientele.

"We're roughly split between leisure guests and business travelers," Long says. "They want to feel like they're staying in a home away from home." Read more about Lodgeur here.

In oil and gas, proper data management can be the difference of millions of dollars in savings. Pandata Tech can run a data quality check for its oil and gas clients — and even engages automation and machine learning for quicker, more thorough results.

Gustavo Sanchez, co-founder and CEO of the company, is looking to bring his data systems into new industries, like health care, where data management can be hectic, overwhelming, and crucial to life-saving opportunities.

"There's so much data, and it's so noisy, that it's hard to know whether the data can be trusted or not," Sanchez says. Read more about Pandata Tech here.

Houston scientist creates a DIY lab concept for flexible and efficient work

Work space

Every scientist needs his or her own space, and each discipline calls for different types of tools and space requirements. Caleb Bashor, a professor at Rice University, along with seven colleagues, created a DIY lab to further research efforts based at the university.

Stemming from the need of a more customized study, Bashor and his team created a setup that combines the control of automated cell-culturing systems that can run continuously for months with the scale of high-throughput systems that grow dozens of cultures at once, according to a news release issued by Rice University.

The DIY lab, eVOLVER, comprises three modules: a customizable "smart sleeve" housing and interface for each culture vessel, a fluidic module that controls movement of liquid in and out of each culture vessel, and a modular hardware infrastructure that simplifies high-volume bi-directional data flow by decoupling each parameter into individual microcontrollers.

"The prototype 16-chamber version of eVOLVER described in the new paper cost less than $2,000, cheaper than what a lab might pay for a single continuous culture bioreactor," Bashor says in the release.

Bashor, who has been at the university since 2017, has worked in science for 15 years and received his post doctorate from Massachusetts Institute of Technology, where he met many of his colleagues that collaborated on eVOLVER.

"If you don't have something to do the job in the lab, you go and you build it," says Bashor. "It might take a few rounds of building and rebuilding, but eventually you get around to having it be something that gives you what you want. In this case, it's something a lot of different academic labs want now, we have actually given this out to dozens of labs."

The DIY initiative has made waves throughout the Rice student body, Bashor shares with InnovationMap. One graduate student, Brandon Wong, tasked to help with the project has shared a how-to for the DIY lab online.

"It's a basic research tool, it's exciting," says Bashor. It's something that can be leveraged for a lot of great research projects inside of the university."

Bashor and his team in the bioengineering department support lead cellular and biomolecular engineering research, which led them to create the lab.

"We turned to DIY electronics and we decided to build it ourselves," Bashor tells InnovationMap. "The process took about three years. We had to learn all of the tools that were out there for doing DIY work and a lot of these tools have showed up in the last ten years."

Rice University's department of bioengineering is a member of the Texas Medical Center and hosts interdisciplinary training programs at MD Anderson Cancer Center and Baylor College of Medicine, according to the school's website.

"This is one of the biggest centers in the world for immunotherapy, particularly clinical immunotherapy, and so we're working with people who do immunotherapy using my special engineering techniques, which mostly involve engineering the way that cells behave to try to more effectively kill cancer," says Bashor.

Houston doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
