A team of bioengineers at Houston's own Rice University have created an implant that can produce insulin for Type 1 diabetics. The device is being created by using 3D printing and smart biomaterials.

Omid Veiseh, an assistant professor of bioengineering, and Jordan Miller, associate professor of bioengineering, have been working on the project for three years and have received support from JDRF by way of a grant. Veiseh has a decade of experience developing biomaterials that protect implanted cell therapies from the immune system an Miller has spent more than 15 years specializing in 3D print tissues with vasculature, or networks of blood vessels.

"If we really want to recapitulate what the pancreas normally does, we need vasculature," Veiseh says in a news release. "And that's the purpose of this grant with JDRF. The pancreas naturally has all these blood vessels, and cells are organized in particular ways in the pancreas. Jordan and I want to print in the same orientation that exists in nature."

The challenge with Type 1 diabetes is balancing insulin intake, and studies estimate that less than a third of Type 1 diabetics in the U.S. are able to achieve target blood glucose levels consistently. Veiseh and Miller are working toward demonstrating that their implants can properly regulate blood glucose levels of diabetic mice for at least six months. To do that, they'll need to give their engineered beta cells the ability to respond to rapid changes in blood sugar levels.

"We must get implanted cells in close proximity to the bloodstream so beta cells can sense and respond quickly to changes in blood glucose," Miller says, adding that the insulin-producing cells should be no more than 100 microns from a blood vessel. "We're using a combination of pre-vascularization through advanced 3D bioprinting and host-mediated vascular remodeling to give each implant several shots at host integration."

Another challenge these experts are facing is a potential delay that can happen if the implant is too slow to respond to high or low blood sugar levels.

"Addressing that delay is a huge problem in this field," Veiseh says. "When you give the mouse — and ultimately a human — a glucose challenge that mimics eating a meal, how long does it take that information to reach our cells, and how quickly does the insulin come out?"

By incorporating blood vessels in their implant, he and Miller hope to allow their beta-cell tissues to behave in a way that more closely mimics the natural behavior of the pancreas.

Houston expert: New technologies are improving lives of those living with type 1 diabetes

Guest column

Type 1 diabetes (T1D) is an autoimmune disease where insulin-producing beta cells in the pancreas are mistakenly destroyed by the body's immune system. Insulin is vital in controlling blood-sugar or glucose levels. Not only do you need proper blood-sugar levels for day-to-day energy, but when blood-sugar levels get too high (hyperglycemia) or too low (hypoglycemia), it can cause serious problems and even death. Because of this, those with T1D are dependent on injections or pumps to survive.

The causes of T1D are not fully known, and there is currently no cure; however, advancing technologies are making it easier to live with T1D.

Monitoring

Those who have had T1D for decades might recall having to pee into a vial and test reagent strips in order to check their blood-sugar levels. Thankfully, this evolved into glucometers, or glucose meters. With a glucometer, those with T1D prick their finger and place a drop on the edge of the test strip, which is connected to the monitor that displays their results. Nowadays, glucometers, much like most T1D tech, can be Bluetooth enabled and sync with a smartphone.

From there, scientists have developed the continuous glucose monitor (CGM) so that those with T1D can monitor their blood sugar 24/7. All you need to do is insert a small sensor under the skin. The sensor then measures glucose levels every few minutes, and that information can then be transmitted to smartphones, computers and even smart watches.

Monitoring blood-sugar levels is vital for those with T1D, particularly because it helps them stay more aware of their body, know what to do and even what to expect, but they also have to actively control those levels by injecting insulin. Think of a monitor as the "check engine" light. It can tell you that there may be a problem, but it won't fix it for you. To fix it, you would need an injection or a pump.

Pumps and artificial pancreas

The development of insulin pumps has made a huge impact on the lives of those with T1D and parents of children with T1D by making it easier to manage their blood-sugar levels. 50 years ago, the prototype of the insulin pump was so large, it had to be a backpack, but with today's technology, it is about the size of a smartphone. The pump is worn on the outside of the body, and it delivers insulin through a tube which is placed under the skin. Insulin pumps mimic the way a pancreas works by sending out small doses of insulin that are short acting. A pump can also be manipulated depending on each person's needs. For example, you can press a button to deliver a dose with meals and snacks, you can remove it or reduce it when active and it can be programmed to deliver more at certain times or suspend delivery if necessary.

One of the most recent and trending developments in T1D research is the artificial pancreas, or more formally referred to as the automated insulin delivery (AID) systems. Essentially, the artificial pancreas is an insulin pump that works with a CGM. The CGM notifies the insulin pump of your blood-sugar reading, which acts accordingly to restore your blood sugar to the target level. The artificial pancreas allows those with T1D to be even more hands off, as it does essentially everything: It continuously monitors blood-sugar levels, calculates how much insulin you would need, which can be done through smart devices, and automatically delivers insulin through the pump.

Living with T1D is a 24/7/365 battle; however, the advances in technology make it easier and safer to live with the disease. Organizations like JDRF play a huge role in investing in research, advocating for government support and more.

November was National Diabetes Awareness Month, and this year is particularly special for JDRF, as it is the 50th year of the organization. JDRF was founded in 1970 by two moms. The community grew to include scientists, lobbyists, celebrities and children—all determined to improve lives and find cures.

Bound by a will stronger than the disease, this year during National Diabetes Awareness Month (NDAM), JDRF celebrates "The Power of Us." We are reflecting on the power of our community and reminding ourselves and the public of how far we've come in the fight against T1D.

Houston startup is off to the races with its innovative running shoes

running start

Despite Houston’s reputation as a sneaker town, there are few actual shoe companies headquartered in the Bayou City. One that is up and running is Veloci Running, an innovative enterprise that combines the founder’s history as a track runner for Rice University with the realities of running in a changing world.

Tyler Strothman started running cross country growing up in Wisconsin and Indiana before moving to Texas to attend Rice in 2020. Naturally, his college life was altered significantly by the COVID-19 pandemic. Unfortunately, Strothman contracted the virus, leading to pneumonia and causing him to consider other plans for his future.

One thing that stood out from Strothman’s running career was how bad his shoes fit.

“Traditional shoes narrowed in, cramped the front of my feet, and it was causing foot pain,” he said in a video interview. “But any other shoes that were shaped to better fit the natural foot shape were more barefoot (style)—they were more minimalist overall. And that was hurting my calf and Achilles. It was pulling on it, kind of like a rubber band.”

Strothman decided to start Veloci and went on to win the annual Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2025. The win secured $50,000 in startup money, which Strothman used to immediately launch his new runner-centered shoe design with himself as the CEO at the age of 24.

Along for the jog was Strothman’s college friend, Austin Escamilla, who serves as chief operating officer. Escamilla believed in Strothman’s vision, but the project immediately ran into snags beyond Veloci’s control, particularly with manufacturing in Asia.

“It was quite a year to start a shoe business, especially dealing with tariffs and global economic trade tensions,” he said in the same video interview. “We've luckily had some really good partners and really solid advisors throughout the journey who've either done it or had some good feedback and advice. It certainly takes a village, but every day is different. So, it's fun to come into work every day and problem solve.”

The flagship Veloci shoe is the Ascent, which comes in both men’s and women’s sizes. It combines the wide toe cage that Strothman wanted with extra support cushion for a softer, easier run. They retail at $180. Strothman has personally been testing them for a year, noticing reduced lower leg pain when he runs.

At the same time, Veloci has attended to some of the more unique running problems in Houston and other hot, Southern states. A combination of heat and humidity makes for a very soggy shoe if not designed with such environments in mind. The Ascent is built to be very open and breathable, allowing hot air to flow and keeping sweat from building up. These various comfort improvements have made the Ascent Strothman’s favorite running shoe.

“I put on more pairs of this Veloci shoe than I have in my other running shoes in the last seven years,” he said

Currently, Veloci is still a very niche brand. Since the company launched last year, they’ve sold roughly 10,000 pairs. Those sales come either directly through their website or from specialty running stores, most of which are located around the Houston area, like Clear Creek Running Company in League City.

Building community around the shoe through these specialty retailers has been a prime marketing strategy. Part of the $50,000 grant went to a custom van that Veloci can take to various 5Ks, runs and events to get people interested in the brand. The personal touch has helped news of Veloci spread through the running world.

“We went to many run clubs throughout the last year,” said Escamillia. “We've been to pretty much every one of the major run clubs at least once or twice. Folks who try on the shoes, love them, become fans and post and repost…. The marketing side's been a lot of fun.”

Intuitive Machines lands $180M NASA contract for lunar delivery mission

to the moon

NASA has awarded Intuitive Machines a $180.4 million Commercial Lunar Payload Services (CLPS) award to deliver science and technology to the moon.

This is the fifth CLPS award the Houston spacetech company has received from NASA, according to a release. It will be the first mission to utilize Intuitive Machines' larger cargo lunar lander, Nova-D.

Known as IM-5, the mission is expected to deliver seven payloads to Mons Malapert, a ridge near the Lunar South Pole, which is a "compelling location for future communications, navigation, and surface infrastructure," according to the release.

“We believe our space infrastructure provides the scalability and flexibility needed to support an increased cadence of new Artemis missions and advance national objectives. This CLPS award accelerates our expansion efforts as we build, connect, and operate the systems powering that infrastructure,” Steve Altemus, CEO of Intuitive Machines, said in the release. “We look forward to working closely with NASA to deliver mission success on IM-5 and to provide sustained operations and persistent connectivity in the cislunar environment and across the solar system.”

The delivery will include the Australian Space Agency’s lunar rover, known as Roo-ver, and another lunar rover from Honeybee Robotics, a part of Jeff Bezos' Blue Origin. Intuitive Machines will also deliver chemical analysis instruments, radiation detectors and other technologies, as well as a capsule named Sanctuary that shows examples of human achievements.

Intuitive Machines previously completed its IM-1 and IM-2 missions, which put the first commercial lunar lander on the moon and achieved the southernmost lunar landing, respectively.

Its IM-3 mission is expected to deliver international payloads to the moon's Reiner Gamma this year. It’s IM-4 mission, funded by a $116.9 million CLPS award, is expected to deliver six science and technology payloads to the Moon’s South Pole in 2027.

The company also announced a $175 million equity investment to fuel growth earlier this month.

TotalEnergies exits U.S. offshore wind sector in $1B federal deal

Energy News

TotalEnergies, a French company whose U.S. headquarters is in Houston, has agreed to redirect nearly $930 million in capital from two offshore wind leases on the East Coast to oil, natural gas and liquefied natural gas (LNG) production.

In its agreement with the U.S. Department of the Interior, TotalEnergies has also promised not to develop new offshore wind projects in the U.S. “in light of national security concerns,” according to a department press release.

Federal agency hails ‘landmark agreement’

The Department of the Interior called the deal a “landmark agreement” that will steer capital “from expensive, unreliable offshore wind leases toward affordable, reliable natural gas projects that will provide secure energy for hardworking Americans.”

Renewable energy advocates object to what they believe is the Trump administration’s mischaracterization of offshore wind projects.

Under the Department of the Interior agreement, the federal government will reimburse TotalEnergies on a dollar-for-dollar basis for the leases, up to the amount that the energy company paid.

“Offshore wind is one of the most expensive, unreliable, environmentally disruptive, and subsidy-dependent schemes ever forced on American ratepayers and taxpayers,” Interior Secretary Doug Burgum said in the announcement. “We welcome TotalEnergies’ commitment to developing projects that produce dependable, affordable power to lower Americans' monthly bills while providing secure U.S. baseload power today — and in the future.”

TotalEnergies cites U.S. policy in move away from U.S. wind power

In the news release, Patrick Pouyanné, chairman and CEO of TotalEnergies, says the company was “pleased” to sign the agreement to support the Trump administration’s energy policy.

“Considering that the development of offshore wind projects is not in the country’s interest, we have decided to renounce offshore wind development in the United States, in exchange for the reimbursement of the lease fees,” Pouyanné says.

TotalEnergies redirects capital to LNG, oil, and natural gas

TotalEnergies will use the $928 million it spent on the offshore wind leases for development of a joint venture LNG plant in the Rio Grande Valley, as well as for production of upstream oil in the Gulf of Mexico and for production of shale gas.

“These investments will contribute to supplying Europe with much-needed LNG from the U.S. and provide gas for U.S. data center development. We believe this is a more efficient use of capital in the United States,” Pouyanné says.

TotalEnergies paid $133.3 million for an offshore wind lease at the Carolina Long Bay project off the coast of North Carolina and $795 million in 2022 for a lease covering a 1,545-megawatt commercial offshore wind facility off the coast of New Jersey.

“TotalEnergies’ studies on these leases have shown that offshore wind developments in the United States, unlike those in Europe, are costly and might have a negative impact on power affordability for U.S. consumers,” TotalEnergies said in a company-issued press release. “Since other technologies are available to meet the growing demand for electricity in the United States in a more affordable way, TotalEnergies considers there is no need to allocate capital to this technology in the U.S.”

Since 2022, TotalEnergies has invested nearly $12 billion to promote the development of oil, LNG, and electricity in the U.S. In 2025, TotalEnergies was the No. 1 exporter of LNG from the U.S.

Industry groups push back on offshore wind pullback

The American Clean Energy Association has pushed back on the Trump administration’s characterization of offshore wind projects.

“The offshore wind industry creates thousands of high-quality, good-paying jobs, and is revitalizing American manufacturing supply chains and U.S. shipyards,” Jason Grumet, the association’s CEO, said in December after the Trump administration paused all leases for large-scale offshore wind projects under construction in the U.S. “It is a critical component of our energy security and provides stable, domestic power that helps meet demand and keep costs low.”

Grumet added that President Trump’s “relentless attacks on offshore wind undermine his own economic agenda and needlessly harm American workers and consumers.” He called for passage of federal legislation that would prevent the White House “from picking winners and losers” in the energy sector and “placing political ideology” above Americans’ best interests.

The National Resources Defense Council offered a similar response to the offshore wind leases being paused.

“In its ongoing effort to prop up waning fossil fuels interests, the administration is taking wilder and wilder swings at the clean energy projects this economy needs,” said Pasha Feinberg, the council’s offshore wind strategist. “Investments in energy infrastructure require business certainty. This is the opposite. If the administration thinks the chilling impacts of this action are limited to the clean energy sector, it is sorely mistaken.”
