Rice University scientists invent new algorithm to fight Alzheimer's

A Seismic Breakthrough

A new breakthrough from researchers at Rice University could unlock the genetic components that determine several human diseases such as Parkinson's and Alzheimer's.

Alzheimer's disease affected 57 million people worldwide in 2021, and cases in the United States are expected to double in the next couple of decades. Despite its prevalence and widespread attention of the condition, the full mechanisms are still poorly understood. One hurdle has been identifying which brain cells are linked to the disease.

For years, it was thought that the cells most linked with Alzheimer's pathology via DNA evidence were microglia, infection-fighting cells in the brain. However, this did not match with actual studies of Alzheimer's patients' brains. It's the memory-making cells in the human brain that are implicated in the pathology.

To prove this link, researchers at Rice, alongside Boston University, developed a computational algorithm called “Single-cell Expression Integration System for Mapping Genetically Implicated Cell Types," or SEISMIC. It allows researchers to zero in on specific neurons linked to Alzheimer's, the first of its kind. Qiliang Lai, a Rice doctoral student and the lead author of a paper on the discovery published in Nature Communications, believes that this is an important step in the fight against Alzheimer's.

“As we age, some brain cells naturally slow down, but in dementia — a memory-loss disease — specific brain cells actually die and can’t be replaced,” said Lai. “The fact that it is memory-making brain cells dying and not infection-fighting brain cells raises this confusing puzzle where DNA evidence and brain evidence don’t match up.”

Studying Alzheimer's has been hampered by the limitations of computational analysis. Genome-wide association studies (GWAS) and single-cell RNA sequencing (scRNA-seq) map small differences in the DNA of Alzheimer's patients. The genetic signal in these studies would often over-emphasize the presence of infection fighting cells, essentially making the activity of those cells too "loud" statistically to identify other factors. Combined with greater specificity in brain regional activity, SEISMIC reduces the data chatter to grant a clearer picture of the genetic component of Alzheimer's.

“We built our SEISMIC algorithm to analyze genetic information and match it precisely to specific types of brain cells,” Lai said. “This enables us to create a more detailed picture of which cell types are affected by which genetic programs.”

Though the algorithm is not in and of itself likely to lead to a cure or treatment for Alzheimer's any time soon, the researchers say that SEISMIC is already performing significantly better than existing tools at identifying important disease-relevant cellular signals more clearly.

“We think this work could help reconcile some contradicting patterns in the data pertaining to Alzheimer’s research,” said Vicky Yao, assistant professor of computer science and a member of the Ken Kennedy Institute at Rice. “Beyond that, the method will likely be broadly valuable to help us better understand which cell types are relevant in different complex diseases.”

Houston hangover pill startup seen on Shark Tank rebrands following multimillion-dollar raise

Three cheers for cheers

When Brooks Powell's Houston-based startup got passed over by the investors on Shark Tank last year, he didn't let it deter him. Instead, the Houston entrepreneur buckled down and started seeking investments off the screen.

It paid off, and Cheers (née Thrive+) recently closed a $2.1 million seed round. The round was lead by NextView Ventures, which has the likes of TaskRabbit, threadUP, and Letgo among its portfolio.

With the new investment, Brooks says the company is rebranding from Thrive, its original moniker, to Cheers.

"Thrive+ doesn't really say anything about what we did or who we are about," Powell says. "We knew we needed something fitting for the alcohol industry but at the same time has the connotation of fun, responsibility, and health."

The process has been daunting, but worth it, Powell says, citing companies like Ring, which changed its company name from Doorbot.

"It would be hard to imagine Amazon buying a company named Doorbot," Powell says.

It's worth noting that Doorbot rebranded also following a similar rejection on Shark Tank.

Once Cheers had its new name, Powell began the process of the transition — relabeling bottles, redoing marketing materials, etc. There's still a long road ahead for the rebranding, but Powell says he wasn't going to drag his feet, since the change would just become more expensive and more challenging. Ring, for instance, had to pay $1 million for its new domain name.

"We wanted to become Cheers as soon as possible, because it would only become harder as time went on," he says.

From student to CEO
Cheers' formula isn't new. The key ingredient, Dihydromyricetin, a natural extract — like caffeine to coffee, which made the FDA process smooth sailing. DHM started being identified as an anti-alcohol treatment in 2012 following experiments on the effects on rats.

Around that time, Powell was a sophomore at Princeton University, and he came across the science surrounding DHM and knew if he could harness the natural extract for commercial use, it'd change the game of hangover health.

"I started working with some of my professors and asking them if it was safe and would it be effective," Powell says.

At the time, there was very little amount of DHM in the United States, so the company became the first to import the ingredient on a large scale.

Powell graduated from Princeton in 2017 and moved his company to its workspace in The Cannon.

Serving up growth
Cheers has seen a tremendous amount of growth over the past year. The company's revenue increased 20 times year over year. A key determiner of success for the company, Powell says, has been strategic marketing and a working product.

"Primarily products such as this, historically, have never worked," he says. "And they've always been marketing toward binge drinkers and partiers."

Another strategy Powell has is giving the company a presence nationwide by having advisers and investors from both coasts.

"What we have tried to do is have our cake and eat it too. We set roots in Houston, but we have our hands in other markets."

In addition to rebranding, Cheers plans to continue its growth, as well as research and development of the product.

Efficient referrals from doctor to doctor could save a life, so this Houston company is setting out to create a network of medical professionals all accessible in an app. Getty Images

Houston-based company is connecting the dots on patient referrals

Diagnosing doctors

When your doctor recommends that you visit another practitioner, it's only natural that you trust the suggestion. But it's one case in which your physician isn't always an expert. Married doctors Justin Bird, an orthopedic surgeon, and Terri-Ann Samuels, a specialist in female pelvic medicine and reconstructive surgery, have long noted that patients are often referred incorrectly.

No big deal, right? Just go to another doctor. But not everyone has that luxury. Bird and Samuels never intended to start their own company. But when Bird lost a patient due to faulty referrals, they knew something had to be done.

"He believes that if she hadn't been bounced around from doctor to doctor, they could have saved her life," says Chris E. Staffel, chief operating officer of Patients We Share, the app that the couple created to fix the broken aspect of the health care system.

In 2015, Bird and Samuels began their company when they were shocked to realize that such an app didn't already exist.

"They started working with physicians around the country who said, 'We really, really need this,' and they also invested in it," recounts Staffel. From those friends, they built a physician advisory board of 15 investors.

Prescribing growth
The project was accepted into Johnson & Johnson's incubator, JLABS in 2016, then TMCx's digital startup program in the spring of 2018.

"They started realizing it was gaining momentum and realized they needed to have business people on board," says Staffel.

They hired Michael Antonoff, a Rice University M.B.A., as CEO. He invited former classmate Staffel to join as COO. Having come from a background in oil and gas, Staffel jumped at the chance to try her hand in a different industry.

With new business clout behind PWS, the company is growing quickly. Currently, PWS is entering its next seed round of $2.5 million that will allow the company to pay salaries of new team members and bring some tech development in-house. Until now, the making of the app itself has been outsourced to Mobisoft Infotech, a company based in Houston and India, which has worked on many projects at the Texas Medical Center. Local Black + Grey Studio is responsible for the design.

PWS has been working with both those teams in recent months to get a prototype app ready for launch. Currently, 100 physicians around the country are part of an invite-only pilot program. Soon, Staffel hopes to allow early adopter doctors who haven't been invited to enroll in the program for free. It will likely be in 2020 that patients will start joining the community, too.

How it works
An index of all the providers on the app allows doctors to easily find practitioners in a particular specialty. But there's more to it. Detailed profiles contribute to machine learning that assures the optimal match every time. Patient reviews will also play a role.

Though referrals were the impetus for the creation of PWS, it may be even more important as a communication tool between doctors, fellow clinicians (anyone from nurse practitioners to physical therapists may be invited to join), and patients. Staffel says participants in the pilot program are already using the messaging system to compare notes on cases, even sending photos from surgery to consult on patient issues.

The app's encryption means that it's HIPAA-compliant. Patients provide permission to discuss their cases via the app. And they can be confident of the quality of care they'll receive. Likely, the app will remain largely invite-only, and everyone who joins will share their National Provider Identifier licenses to be vetted against the federal database.

Doctors will communicate directly with patients through the app, but will also share resources digitally. Instead of making copy after copy of information about post-surgical care, for instance, the physician need only press a button to share a link.

Eventually, the goal is for PWS to be used not just nationally, but internationally, not just by individuals, but by whole hospital systems. A world in which doctors can compare notes around globe could be a little safer for us all.

5 Texas companies present the future of health care at TMCx's Demo Day

Homegrown heroes

After four months of product design, networking with medical professionals, pitching to investors, and more, 23 startup leaders had just a few minutes to show the medical community what they've achieved and where they're going next.

Over 700 attendees made it to TMCx's 7th Demo Day or tuned in online to see the results of Houston's award-winning medical devices accelerator program.

"It's really the draw of the experts within our 23 hospitals and clinics that really makes us quite special in our ecosystem compared to the East and West coasts," Texas Medical Center CEO Bill McKeon says. "We're proud to call ourselves the Third Coast of the life sciences."

The cohort, which is the most international to date with nine international companies, has already raised $73 million and confirmed 108 signed agreements for medical professional partnerships.

"The thing that cracks me up from time to time," says Erik Halvorsen, director of the TMC Innovation Institute, "is when you see these talks that say, 'what can the Houston ecosystem learn from Silicon Valley.' Well you know what, I think we're ready to flip that, and say, 'here's what can Silicon Valley learn from us here in Houston — what we've built and where we're headed.'"

From a wearable device that reduces back pain to a new technology that reduces suicidal thoughts, the cohort's presentations didn't disappoint. While all the cohorts made business connections to Houston in the months they were at TMCx, five of the 23 companies are based in Texas. Here are the companies with Lone Star State roots.

Articulate Labs

Herbie Kirn, co-founder and chief scientific officer of Articulate Labs, lost his leg from the knee down in a motorcycle accident and quickly wore through his other knee's cartilage. If he didn't do sufficient rehabilitation and physical therapy, he would lose function of that leg too.

Over 14 million people in the United States individuals suffer from chronic knee problems; however, whether it be due to time or cost, over 70 percent of those affected cannot attend the prescribed physical therapy.

Dallas-based Articulate Labs has a solution. The KneeStim device allows the patient to turn daily activities into rehabilitation exercises.

The company has raised a little over $500,000 already, but looks to raise $1 million with its next round of funding. Articulate Labs is also looking for more scientific and strategic partners.

Intelligent Implants

Intelligent Implant's co-founder, Juan Pardo, told the crowd at Demo Day that his company's device allows for 50 percent faster bone growth in patients.

Chronic lower back pain can result in a need for spinal fusion surgery — and 40 percent of those surgeries fail, says Juan Pardo, co-founder of Intelligent Implants, which has an office in Houston. Pardo and his team have come up with an implant that tracks post-op healing and introduces electronic stimulation wirelessly.

The device is the same size and shape as the spacer that surgeons currently use, but contains a technology that can deliver electronic stimulation therapy and monitor progress without needing batteries. The doctor is able to adjust treatment remotely, and the device can heal the patient 50 percent faster than the standard care.

Intelligent Implants was announced as the first in-residence company at the Center for Device Innovation by Johnson and Johnson and also launched its large animal studies. The company has a goal to raise $1.6 million, and has already secured $900,000 — $250,000 of which came from the new TMC Venture Fund.

Noleus Technologies

Swarna Balasubramaniam watched helplessly as her mom slowly healed from gastrointestinal surgery. She couldn't eat and had trouble sleeping — both of which hindered her ability to heal quickly.

Balasubramaniam, founder of Houston-based Noleus Technologies, created a solution that reduces swelling in the bowels after operation. The disposable device is inserted into the abdomen at the time of surgery, and folds up like a fan to be removed without another surgery.

The invention is attractive to all parties involved. Patients are able to heal quicker, and surgeons are able to provide better care for their patients. Additionally, hospitals, which have bundled reimbursement for surgeries like this, are able to shorten the recovery time for patients thus reducing the costs spent on caring for the patient. Balasubramaniam says she estimates the device saving hospitals $4,000 per patient.

Vax-Immune Diagnostics

LabReady ensures samples make it from the patient to the lab without compromising the quality of the sample.

Over 70 percent of care decisions come from lab results, but more than 20 percent of microbiology lab tests are inaccurate due to problems in transport from the patient to the lab. Leonard Weisman, founder and chief technology officer of Houston-based Vax-Immune Diagnostics, invented Lab Ready — a tool for protecting the quality of the sample for testing.

The device is easy for patients to use at home and send to the lab directly, and the device is likewise easy to use by lab technicians.

Lab Ready is prepared to launch in 2019, immediately following FDA approval. Vax-Immune is on track to meet its funding goal of $5 million in the first quarter of 2019.

VenoStent

VenoStent wants every external stent procedure is successful on its first try.

Patients with kidney disease or diabetes have four chances to get an external stent successfully inserted into their arms for dialysis treatment, and the current standard of care results in a failure in half of these access sites, says Tim Biore, founder of Houston-based VenoStent.

It was Biore's vision to create a device that allows a successful stent implementation on the first try. VenoStent's SelfWrap is made from a shape-memory polymer that uses body heat to mold the stent into the vein-artery junction.

One in eight people suffer from kidney disease, and Biore says SelfWrap would save Medicare upwards of $200 million annually, while improving the success rate by 20 to 30 percent.

VenoStent has seven signed agreements from partners as a result of the accelerator program. The company is seeking $2.4 million to continue manufacturing as they await FDA clearance — expected in early 2022.

Pioneering cohousing development opens in Houston's historic 2nd Ward

Housing in Hou

An experimental, multi-generational building in the East End is now open and accepting residents. Only 10 of the 33 units remain available at East End Commons, the first project from CoHousing Houston.

Located at 115 Lenox, East End Commons was first conceived in 2017 and is designed to combine the security of home ownership with the community aspect of apartment life, essentially a condominium but with added focus on bringing neighbors together.

Units range from 900-2,000 square feet, offering ample private home space, but with a large Common House area and central courtyard for gatherings, working, and interaction. Large front porches encourage people to spend time outside where they can meet their neighbors, as do extensive foot paths for casual meetings.

"At East End Commons, you know your neighbors before you move in — so you have a network of people and spaces that are immediately there for you," said founding resident Kelli Soika. "We designed for larger shared spaces versus larger personal spaces in order to foster the breakdown of the barriers that lead to loneliness."

Combating loneliness and isolation is certainly necessary. A 2025 survey conducted by the American Psychological Association shows that most Americans feel a sense of societal division and lonely. A loss of "third spaces," where people gather outside the home or work, is a prime factor. East End Commons aims to alleviate some of that disconnectedness.

"I wanted to live in a neighborhood that is imbued with a sense of community above the individual, like we have all experienced in Houston during times of disaster recovery," said Lynn Morstead, one of East End Commons‘ founding residents. "In those instances, such as Hurricane Harvey, we surface from our separateness and come together in new and unexpected ways. With East End Commons, the goal is to translate that notion beyond a set period of time and make it a fixture of everyday life. I call it 'disaster-free neighborliness.'"

East End Commons was designed by Kathleen English of English + Associates. Sustainability is part of the project's design, with amenities such as geothermal heating and cooling exchange HVAC, pre-heated water systems, low-energy use air conditioning and heating, and native landscaping.

Prices for units range from $300,000 to the $900,000s, which can be more than double the home price in the rapidly gentrifying East End. HOA fees not only help maintain communal areas, they also cover shared internet, water, and other communal expenses. Similarly, government of the building is handled democratically via a community board that aims to make decisions by building consensus.

MD Anderson president to retire after nine years, interim successor named

retirement plan

An era is ending at The University of Texas MD Anderson Cancer Center.

On Aug. 26, Dr. Peter WT Pisters announced his plans to retire from his role as president of the comprehensive cancer center. He will work on a smooth transition of leadership with interim president Dr. Jeffrey E. Lee throughout September.

“I first arrived at UT MD Anderson 32 years ago with a passion for doing everything I could to advance our mission to end cancer. Serving as the only faculty member to become president, and now marking nine years in the role, I can say with great pride and gratitude that there is no better place than UT MD Anderson to turn hope into healing for patients and families everywhere,” Pisters said in a news release. “With a timeless strategy, a strong leadership team, unprecedented levels of financial health, and a priceless culture anchored in our deeply held Core Values, now is the right time for me to transition to other opportunities. UT MD Anderson has never been stronger, and its future has never been brighter.”

Pisters assumed the presidency in 2017 and helped launch some of the most cutting-edge new clinics in MD Anderson history. One of those was the James P. Allison Institute, named for the Nobel Laureate scientist who discovered a way to suppress immune response on tumors so that immune cells would attack cancer cells instead. As head of his titular clinic, Allison pioneered several new immunotherapies against cancer.

Pisters also oversaw the creation of the Institute for Data Science in Oncology in 2024, an innovative consortium of scientists dedicated to enhancing single-cell imaging to improve precision in cancer treatments. The institute also brought together teams to use data-driven analytics regarding safety, quality and access.

The UT System Board of Regents praised the leadership and work of Pisters in a statement, wishing him well in the next phase of his career.

“The Board of Regents and I are profoundly grateful to Dr. Pisters for his exceptional presidency over the past nine years and for thoughtfully concluding his service when UT MD Anderson is thriving at its best position of peak performance, strength and impact. We wish him our very best with his retirement and in his next chapter,” Kevin P. Eltife, chairman of the UT System Board of Regents, added in the release.

Houston e-commerce giant Cart.com launches government-focused subsidiary

government branch

Houston e-commerce and logistics unicorn Cart.com has launched a new subsidiary.

Cart Government Solutions (CGS), which was announced earlier this week, will provide supply chain and logistics services and software for the federal and state government sectors. The new subsidiary will be headquartered in Washington, D.C., and operate out of about 6 million square feet of secure warehouse space across 14 U.S. facilities, according to a news release from Cart.com. It will support both domestic and overseas logistics.

Industry veteran Gregg Zegras will lead the new entity as president. Zegras previously served as Cart.com's chief revenue officer, according to LinkedIn. Before that, he served as president of Connecticut-based Pitney Bowes Global eCommerce, a digital shipping solutions company.

Remington Tonar, Cart.com's co-founder, will serve as CGS's chief innovation officer.

“Government agencies face procurement and logistics challenges that many commercial platforms simply weren’t built to solve,” Zegras said in the news release. “Cart Government Solutions exists to change that. We’re combining the speed and innovation of a technology company with the compliance rigor, security, and operational depth that federal and state customers require, and we’re doing it with a team that has spent careers working alongside and inside these agencies.”

According to the company, CGS will focus on meeting compliance and security requirements in the public sector. Some of the services the new entity will offer include:

  • Inventory management
  • Cold-chain and specialty storage for pharmaceuticals, medical devices and regulated goods
  • Enterprise-grade supply chain software
  • Government-compliant webstores and online ordering portals
  • Cybersecurity operations

Cart.com has been serving the public sector since 2022, when the company began distributing COVID-19 health supplies nationwide, according to the news release. Through that pandemic-era contract, the company reports it moved more than 725 million units, with an average of under two days per shipment.

Cart.com was founded in Houston in 2020, though it briefly moved its headquarters to Austin. The company reached unicorn status with its $60 million Series C raise in 2023. It most recently raised $180 million in growth capital from private equity firm Springcoast Partners in March, which put the startup over the $1 billion in fundraising mark in just six years.

At the time, Cart.com said it planned to scale its logistics network, expand AI capabilities and develop workflow automation tools.

Houston-based KBR Inc. also recently launched a government services spinoff. Read more here.
