Researchers and scientists at Rice University and Houston Methodist are developing a “sleep cap” that aims to protect the brain against dementia and other similar diseases by measuring and improving deep sleep.

The project is a collaboration between Rice University engineering professors Daniel Preston, Vanessa Sanchez and Behnaam Aazhang; and Houston Methodist neurologist Dr. Timea Hodics and Dr. Gavin Britz, director of the Houston Methodist Neurological Institute and chairman of the Department of Neurosurgery.

According to Rice, deep sleep is essential for clearing waste products from the brain and nightly “cleaning cycles” help remove toxic proteins. These toxic proteins, like amyloids, can accumulate during the day and are linked to Alzheimer’s disease and other neurological issues.

Aazhang, director of the Rice Neuroengineering Initiative, and his team are building a system that not only tracks the brain’s clearing process but can also stimulate it, improving natural mechanisms that protect against neurodegeneration.

Earlier proof-of-concept versions of the caps successfully demonstrated the promise of this approach; however, they were rigid and uncomfortable for sleep.

Preston and Sanchez will work to transform the design of the cap into a soft, lightweight, textile-based version to make sleep easier, while also allowing the caps to be customizable and tailored for each patient.

“One of the areas of expertise we have here at Rice is designing wearable devices from soft and flexible materials,” Preston, an assistant professor of mechanical engineering, said in a news release. “We’ve already shown this concept works in rigid device prototypes. Now we’re building a soft, breathable cap that people can comfortably wear while they sleep.”

Additionally, the research team is pursuing ways to adapt their technology to measure neuroinflammation and stimulate the brain’s natural plasticity. Neuroinflammation, or swelling in the brain, can be caused by injury, stroke, disease or lifestyle factors and is increasingly recognized as a driver of neurodegeneration, according to Rice.

“Our brain has an incredible ability to rewire itself,” Aazhang added in the release. “If we can harness that through technology, we can open new doors for treating not just dementia but also traumatic brain injury, stroke, Parkinson’s disease and more.”

The project represents Rice’s broader commitment to brain health research and its support for the Dementia Prevention Research Institute of Texas (DPRIT), which passed voter approval last week. The university also recently launched its Rice Brain Institute.

As part of the project, Houston Methodist will provide access to clinicians and patients for early trials, which include studies on patients who have suffered traumatic brain injury and stroke.

“We have entered an era in neuroscience that will result in transformational cures in diseases of the brain and spinal cord,” Britz said in the release. “DPRIT could make Texas the hub of these discoveries.”

Houston researchers tap into tech to provide new brain-related health care solutions

research roundup

Research, perhaps now more than ever, is crucial to expanding and growing innovation in Houston — and it's happening across the city right under our noses.

In InnovationMap's latest roundup of research news, three Houston institutions are working on brain-related health care solutions thanks to technologies.

A University of Houston researcher is tapping into technology to better treat brain injuries and conditions that scientists have not yet figured out treatment for. Badri Roysam, the current chair of electrical and computer engineering at UH and a Hugh Roy and Lillie Cranz Cullen University Professor, and his team have created a new computational image analysis methods based on deep neural networks.

"We are interested in mapping and profiling unhealthy and drug-treated brain tissue in unprecedented detail to reveal multiple biological processes at once - in context," Roysam says in a UH press release about his latest paper published in Nature Communications. "This requires the ability to record high-resolution images of brain tissue covering a comprehensive panel of molecular biomarkers, over a large spatial extent, e.g., whole-brain slices, and automated ability to generate quantitative readouts of biomarker expression for all cells."

Roysam's system, which was developed at the the National Institute of Neurological Disorders and Stroke, analyzes the images on UH's supercomputer automatically and can reveal multiple processes at once – the brain injury, effects of the drug being tested and the potential side effects of the drug, per the release.

"Compared to existing screening techniques, using iterative immunostaining and computational analysis, our methods are more flexible, scalable and efficient, enabling multiplex imaging and computational analysis of up to 10 – 100 different biomarkers of interest at the same time using direct or indirect IHC immunostaining protocols," says Roysam in the release.

The open-source toolkit, which was developed thanks to a $3.19 million grant from the National Institute of Health, is also adaptable to other tissues.

"We are efficiently overcoming the fluorescence signal limitations and achieving highly enriched and high-quality source imagery for reliable automated scoring at scale," says Roysam. "Our goal is to accelerate system-level studies of normal and pathological brains, and pre-clinical drug studies by enabling targeted and off-target drug effects to be profiled simultaneously, in context, at the cellular scale."

Houston Methodist and Rice University launch new collaboration to use robotics for clinical solutions

Rice University and Houston Methodist have teamed up to create a new partnership and to launch the Center for Translational Neural Prosthetics and Interfaces in order to bring together scientists, clinicians, engineers, and surgeons to solve clinical problems with neurorobotics.

"This will be an accelerator for discovery," says the new center's co-director, Dr. Gavin Britz, chair of the Houston Methodist Department of Neurosurgery, in a news release. "This center will be a human laboratory where all of us — neurosurgeons, neuroengineers, neurobiologists — can work together to solve biomedical problems in the brain and spinal cord. And it's a collaboration that can finally offer some hope and options for the millions of people worldwide who suffer from brain diseases and injuries."

The center will have representatives from both Rice and Houston Methodist and also plans to hire three additional engineers who will have joint appointments at Houston Methodist and Rice.

"The Rice Neuroengineering Initiative was formed with this type of partnership in mind," says center co-director Behnaam Aazhang, Rice's J.S. Abercrombie Professor of Electrical and Computer Engineering, who also directs the neuroengineering initiative. "Several core members, myself included, have existing collaborations with our colleagues at Houston Methodist in the area of neural prosthetics. The creation of the Center for Translational Neural Prosthetics and Interfaces is an exciting development toward achieving our common goals."

The team will have a presence on the Rice campus with 25,000 square feet of space in the Rice Neuroengineering Initiative laboratories and experimental spaces in the university's BioScience Research Collaborative. The space at Houston Methodist is still being developed.

"This partnership is a perfect blend of talent," says Rice's Marcia O'Malley, a core member of both the new center and university initiative. "We will be able to design studies to test the efficacy of inventions and therapies and rely on patients and volunteers who want to help us test our ideas. The possibilities are limitless."

Houston institutions launch Project Metis to position region as global leader in brain health

brain trust

Leaders in Houston's health care and innovation sectors have joined the Center for Houston’s Future to launch an initiative that aims to make the Greater Houston Area "the global leader of brain health."

The multi-year Project Metis, named after the Greek goddess of wisdom and deep thought, will be led by the newly formed Rice Brain Institute, The University of Texas Medical Branch's Moody Brain Health Institute and Memorial Hermann’s comprehensive neurology care department. The initiative comes on the heels of Texas voters overwhelmingly approving a ballot measure to launch the $3 billion, state-funded Dementia Prevention and Research Institute of Texas (DPRIT).

According to organizers, initial plans for Project Metis include:

  • Creating working teams focused on brain health across all life stages, science and medical advances, and innovation and commercialization
  • Developing a regional Brain Health Index to track progress and equity
  • Implanting pilot projects in areas such as clinical care, education and workplace wellness
  • Sharing Houston’s progress and learnings at major international forums, including Davos and the UN General Assembly

The initiative will be chaired by:

  • Founding Chair: Dr. Jochen Reiser, President of UTMB and CEO of the UTMB Health System
  • Project Chair: Amy Dittmar, Howard R. Hughes Provost and Executive Vice President of Rice University
  • Project Chair: Dr. David L. Callender, President and CEO of Memorial Hermann Health System

The leaders will work with David Gow, Center for Houston’s Future president and CEO. Gow is the founder and chairman of Gow Media, InnovationMap's parent company.

“Now is exactly the right time for Project Metis and the Houston-Galveston Region is exactly the right place,” Gow said in a news release. “Texas voters, by approving the state-funded Dementia Prevention Institute, have shown a strong commitment to brain health, as scientific advances continue daily. The initiative aims to harness the Houston’s regions unique strengths: its concentration of leading medical and academic institutions, a vibrant innovation ecosystem, and a history of entrepreneurial leadership in health and life sciences.”

Lime Rock Resources, BP and The University of Texas MD Anderson Cancer Center served as early steering members for Project Metis. HKS, Houston Methodist and the American Psychiatric Association Foundation have also supported the project.

An estimated 460,000 Texans are living with dementia, according to the Alzheimer’s Association, and more than one million caregivers support them.

“Through our work, we see both the immense human toll of brain-related illness and the tremendous potential of early intervention, coordinated care and long-term prevention," Callender added in the release. "That’s why this bold new initiative matters so much."

Texas launches cryptocurrency reserve with $5 million Bitcoin purchase

Money Talks

Texas has launched its new cryptocurrency reserve with a $5 million purchase of Bitcoin as the state continues to embrace the volatile and controversial digital currency.

The Texas Comptroller’s Office confirmed the purchase was made last month as a “placeholder investment” while the office works to contract with a cryptocurrency bank to manage its portfolio.

The purchase is one of the first of its kind by a state government, made during a year where the price of Bitcoin has exploded amid the embrace of the digital currency by President Donald Trump’s administration and the rapid expansion of crypto mines in Texas.

“The Texas Legislature passed a bold mandate to create the nation’s first Strategic Bitcoin Reserve,” acting Comptroller Kelly Hancock wrote in a statement. “Our goal for implementation is simple: build a secure reserve that strengthens the state’s balance sheet. Texas is leading the way once again, and we’re proud to do it.”

The purchase represents half of the $10 million the Legislature appropriated for the strategic reserve during this year’s legislative session, but just a sliver of the state’s $338 billion budget.

However, the purchase is still significant, making Texas the first state to fund a strategic cryptocurrency reserve. Arizona and New Hampshire have also passed laws to create similar strategic funds but have not yet purchased cryptocurrency.

Wisconsin and Michigan made pension fund investments in cryptocurrency last year.

The Comptroller’s office purchased the Bitcoin the morning of Nov. 20 when the price of a single bitcoin was $91,336, according to the Comptroller’s office. As of Friday afternoon, Bitcoin was worth slightly less than the price Texas paid, trading for $89,406.

University of Houston energy economist Ed Hirs questioned the state’s investment, pointing to Bitcoin’s volatility. That makes it a bad investment of taxpayer dollars when compared to more common investments in the stock and bond markets, he said.

“The ordinary mix [in investing] is one that goes away from volatility,” Hirs said. “The goal is to not lose to the market. Once the public decides this really has no intrinsic value, then it will be over, and taxpayers will be left holding the bag.”

The price of Bitcoin is down significantly from an all-time high of $126,080 in early October.

Lee Bratcher, president of the Texas Blockchain Council, argued the state is making a good investment because the price of Bitcoin has trended upward ever since it first launched in early 2009.

“It’s only a 16-year-old asset, so the volatility, both in the up and down direction, will smooth out over time,” Bratcher said. “We still want it to retain some of those volatility characteristics because that’s how we could see those upward moves that will benefit the state’s finances in the future.”

Bratcher said the timing of the state’s investment was shrewd because he believes it is unlikely to be valued this low again.

The investment comes at a time that the crypto industry has found a home in Texas.

Rural counties have become magnets for crypto mines ever since China banned crypto mining in 2021 and Gov. Greg Abbott declared “Texas is open for crypto business” in a post on social media.

The state is home to at least 27 Bitcoin facilities, according to the Texas Blockchain Council, making it the world’s top crypto mining spot. The two largest crypto mining facilities in the world call Texas home.

The industry has also come under criticism as it expands.

Critics point to the industry’s significant energy usage, with crypto mines in the state consuming 2,717 megawatts of power in 2023, according to the comptroller’s office. That is enough electricity to power roughly 680,000 homes.

Crypto mines use large amounts of electricity to run computers that run constantly to produce cryptocurrencies, which are decentralized digital currencies used as alternatives to government-backed traditional currencies.

A 2023 study by energy research and consulting firm Wood Mackenzie commissioned by The New York Times found that Texans’ electric bills had risen nearly 5%, or $1.8 billion per year, due to the increase in demand on the state power grid created by crypto mines.

Residents living near crypto mines have also complained that the amount of job creation promised by the facilities has not materialized and the noise of their operation is a nuisance.

“Texas should be reinvesting Texan’s tax money in things that truly bolster the economy long term, living wage, access to quality healthcare, world class public schools,” said state Sen. Molly Cook, D-Houston, who voted against the creation of the strategic fund. “Instead it feels like they’re almost gambling our money on something that is known to be really volatile and has not shown to be a tide that raises all boats.”

State Sen. Charles Schwertner, R-Georgetown, who authored the bill that created the fund, said at the time it passed that it will allow Texas to “lead and compete in the digital economy.”

Houston-based HPE wins $931M contract to upgrade military data centers

defense data centers

Hewlett Packard Enterprise (HPE), based in Spring, Texas, which provides AI, cloud, and networking products and services, has received a $931 million contract to modernize data centers run by the federal Defense Information Systems Agency.

HPE says it will supply distributed hybrid multicloud technology to the federal agency, which provides combat support for U.S. troops. The project will feature HPE’s Private Cloud Enterprise and GreenLake offerings. It will allow DISA to scale and accelerate communications, improve AI and data analytics, boost IT efficiencies, reduce costs and more, according to a news release from HPE.

The contract comes after the completion of HPE’s test of distributed hybrid multicloud technology at Defense Information Systems Agency (DISA) data centers in Mechanicsburg, Pennsylvania, and Ogden, Utah. This technology is aimed at managing DISA’s IT infrastructure and resources across public and private clouds through one hybrid multicloud platform, according to Data Center Dynamics.

Fidelma Russo, executive vice president and general manager of hybrid cloud at HPE, said in a news release that the project will enable DISA to “deliver innovative, future-ready managed services to the agencies it supports that are operating across the globe.”

The platform being developed for DISA “is designed to mirror the look and feel of a public cloud, replicating many of the key features” offered by cloud computing businesses such as Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform, according to The Register.

In the 1990s, DISA consolidated 194 data centers into 16. According to The Register, these are the U.S. military’s most sensitive data centers.

More recently, in 2024, the Fort Meade, Maryland-based agency laid out a five-year strategy to “simplify the network globally with large-scale adoption of command IT environments,” according to Data Center Dynamics.
