When it comes to flying cars, Jeff Chimenti wants to give Elon Musk a run for his money — even though Musk, famously, has a lot of that.

But Chimenti is confident that his startup, Aviator Cycles, might be one of the first to get a vehicle off the ground and up into consumer markets. That's because he's not focusing on cars at all — the prototype, unveiled at a recent promotional event in the Woodlands, is a critical propulsion system for what Chimenti calls a personal air vehicle, or PAV.

The PAVs that Aviator Cycles plans to make are more like motorcycles or four-wheelers and intended for recreational use — but the high-tech system could change how other designers make flying vehicles.

"All of this is really happening," says Chimenti, a Houston-based investor and chief visionary officer and co-founder for the startup. "We're pushing it forward."

And, hopefully, upward. Aviator Cycles's first PAV doesn't fly yet, but smaller models have, and Chimenti expects to see a successful launch within one year. The company is making PAVs because there's a lot of red tape around making cars — traffic systems will need to be redrafted.

So for now, the unique propulsion system, which has come a long way since co-founder Jesse Marcel made his first patent on it before the company was even made, is being fastened to the Aerorunner GSX, a sports vehicle that will flutter from about four feet off the ground for safety.

Aviator Cycles plans to start taking reservations for these in the next six months. But Marcel says that his proprietary propulsion system will eventually make its way to other companies and vehicles; Audi, Porsche and Boeing, for example, have announced flying car projects in recent years.

All this innovation is part of a push toward alternative transportation, but it feels like a resurgent space race — just a little lower this time. Aviator Cycles, based in Spokane, Washington, isn't the only manufacturer. In 2018, California-based Hoversurf announced a hoverbike with a set of helicopter blades. It was supposed to ship out earlier this year for $150,000. Across the world — in Britain and Israel, for example — companies are developing bikes to compete in a brand-new flying vehicle market.

"Everybody that designs is great, but they're ultimately going to have to use our propulsion system," says Chimenti.

A new kind of 4x4 might fly, literally, in the Pacific Northwest, where the culture is all hiking and being outside. Texans, though, tend to have a better relationship with their air-conditioners than the great outdoors. Houston, especially, is mostly the urban sprawl of twisting highways — the same unregulatable stretch of concrete that Chimenti has avoided making vehicles for.

But Chimenti is optimistic about the potential for Space City. Last October, the Houston City Council gave $18.8 million to develop the Houston Spaceport, a kind of "mission control" for the future of commercial alternative transportation. Near Ellington Airport, the site has launch pads and lab space — but, maybe most excitingly for people like Chimenti, it has a tech incubator for developers to design and test their equipment.

Houston, then, has a historical stake in how we explore the space above our heads — and what's left for the regular person to explore is closer, below the stratosphere. If Houston has already been instrumental in getting all the way up there, then some light hovering will be nothing. When it comes to flying motocross, Chimenti says, Houston won't have a problem.

Houston foundation grants $27M to support Texas chemistry research

fresh funding

Houston-based The Welch Foundation has doled out $27 million in its latest round of grants for chemical research, equipment and postdoctoral fellowships.

According to a June announcement, $25.5 million was allocated for the foundation's longstanding research grants, which provide $100,000 per year in funding for three years to full-time, regular tenure or tenure-track faculty members in Texas. The foundation made 85 grants to faculty at 16 Texas institutions for 2025, including:

  • Michael I. Jacobs, assistant professor in the chemistry and biochemistry department at Texas State University, who is investigating the structure and thermodynamics of intrinsically disordered proteins, which could "reveal clues about how life began," according to the foundation.
  • Kendra K. Frederick, assistant professor in the biophysics department at The University of Texas Southwestern Medical Center, who is studying a protein linked to Parkinson’s disease.
  • Jennifer S. Brodbelt, professor in chemistry at The University of Texas at Austin, who is testing a theory called full replica symmetry breaking (fullRSB) on glass-like materials, which has implications for complex systems in physics, chemistry and biology.

Additional funding will be allocated to the Welch Postdoctoral Fellows of the Life Sciences Research Foundation. The program provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas. Two fellows from Rice University and Baylor University will receive $100,000 annually for three years.

The Welch Foundation also issued $975,000 through its equipment grant program to 13 institutions to help them develop "richer laboratory experience(s)." The universities matched funds of $352,346.

Since 1954, the Welch Foundation has contributed over $1.1 billion for Texas-nurtured advancements in chemistry through research grants, endowed chairs and other chemistry-related ventures. Last year, the foundation granted more than $40.5 million in academic research grants, equipment grants and fellowships.

“Through funding basic chemical research, we are actively investing in the future of humankind,” Adam Kuspa, president of The Welch Foundation, said the news release. “We are proud to support so many talented researchers across Texas and continue to be inspired by the important work they complete every day.”

New Houston biotech co. developing capsules for hard-to-treat tumors

biotech breakthroughs

Houston company Sentinel BioTherapeutics has made promising headway in cancer immunotherapy for patients who don’t respond positively to more traditional treatments. New biotech venture creation studio RBL LLC (pronounced “rebel”) recently debuted the company at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.

Rima Chakrabarti is a neurologist by training. Though she says she’s “passionate about treating the brain,” her greatest fervor currently lies in leading Sentinel as its CEO. Sentinel is RBL’s first clinical venture, and Chakrabarti also serves as cofounder and managing partner of the venture studio.

The team sees an opportunity to use cytokine interleukin-2 (IL-2) capsules to fight many solid tumors for which immunotherapy hasn't been effective in the past. “We plan to develop a pipeline of drugs that way,” Chakrabarti says.

This may all sound brand-new, but Sentinel’s research goes back years to the work of Omid Veiseh, director of the Rice Biotechnology Launch Pad (RBLP). Through another, now-defunct company called Avenge Bio, Veiseh and Paul Wotton — also with RBLP and now RBL’s CEO and chairman of Sentinel — invested close to $45 million in capital toward their promising discovery.

From preclinical data on studies in mice, Avenge was able to manufacture its platform focused on ovarian cancer treatments and test it on 14 human patients. “That's essentially opened the door to understanding the clinical efficacy of this drug as well as it's brought this to the attention of the FDA, such that now we're able to continue that conversation,” says Chakrabarti. She emphasizes the point that Avenge’s demise was not due to the science, but to the company's unsuccessful outsourcing to a Massachusetts management team.

“They hadn't analyzed a lot of the data that we got access to upon the acquisition,” explains Chakrabarti. “When we analyzed the data, we saw this dose-dependent immune activation, very specific upregulation of checkpoints on T cells. We came to understand how effective this agent could be as an immune priming agent in a way that Avenge Bio hadn't been developing this drug.”

Chakrabarti says that Sentinel’s phase II trials are coming soon. They’ll continue their previous work with ovarian cancer, but Chakrabarti says that she also believes that the IL-2 capsules will be effective in the treatment of endometrial cancer. There’s also potential for people with other cancers located in the peritoneal cavity, such as colorectal cancer, gastrointestinal cancer and even primary peritoneal carcinomatosis.

“We're delivering these capsules into the peritoneal cavity and seeing both the safety as well as the immune activation,” Chakrabarti says. “We're seeing that up-regulation of the checkpoint that I mentioned. We're seeing a strong safety signal. This drug was very well-tolerated by patients where IL-2 has always had a challenge in being a well-tolerated drug.”

When phase II will take place is up to the success of Sentinel’s fundraising push. What we do know is that it will be led by Amir Jazaeri at MD Anderson Cancer Center. Part of the goal this summer is also to create an automated cell manufacturing process and prove that Sentinel can store its product long-term.

“This isn’t just another cell therapy,” Chakrabarti says.

"Sentinel's cytokine factory platform is the breakthrough technology that we believe has the potential to define the next era of cancer treatment," adds Wotton.
