A Houston-based company is taking a medicine-free approach to target brain neurologically associated with mental illness.

Nexalin Technology’s patented, FDA-cleared frequency-based waveform targets key centers of the midbrain to support the normalization of neurochemicals through a process known as Transcranial Alternating Current Stimulation (tACS). Delivered via a non-invasive device, the treatment gently stimulates the hypothalamus and midbrain, helping to “reset networks associated with symptoms” of anxiety and insomnia. Early clinical evidence suggests this approach can promote healthier brain function and improved sleep.

Through its recently appointed scientific advisory board (SAB), Nexalin also aims to target Alzheimer’s disease with a clinical development pipeline supported by published data and internal data from studies involving its proprietary DIFS technology. Nexalin’s Gen-2 SYNC and Gen-3 Halo headset delivers the DIFS, which is a waveform that can penetrate deep brain structures implicated in cognitive decline and mental illness.

The board includes experts in neurology, neuroimaging and neurodegenerative diseases with Dr. Mingxiong Huang, Dr. David Owens, and Dr. Abe Scheer coming on board. Nexalin plans to initiate new Alzheimer’s-focused clinical studies in the Q3 2025 by incorporating cognitive testing, imaging biomarkers, and guided metrics to assess treatment efficacy and neural activation.

“I am excited to work alongside Nexalin’s leadership and fellow SAB members to help guide the next generation of non-invasive neuromodulation therapies,” Huang said in a news release. “The intersection of neuroimaging, brain stimulation, and clinical science holds enormous potential for treating neurodegenerative disease.”

Recently, Nexalin’s proprietary neurostimulation device moved forward with a clinical trial that evaluated its treatment of anxiety disorders and chronic insomnia in Brazil. The first of Nexalin’s Gen-2 15-milliamp neurostimulation devices was shipped to São Paulo, Brazil, and the study will be conducted at the Instituto de Psiquiatria University Hospital (IPq-HCFMUSP). The shipments aim to support the launch of a Phase II clinical trial in adult patients suffering from anxiety and insomnia. The Nexalin Gen-2 15-milliamp neurostimulation device has also been approved in China, Brazil and Oman. Its Gen 1 device first received FDA clearance in 2003, according to the company's website.

The company also enrolled the first patients in its clinical trial at the University of California, San Diego, in collaboration with the VA San Diego Healthcare System for its Nexalin HALO, which looks to treat mild traumatic brain injury and post-traumatic stress disorder in military personnel and the civilian population.

making waves

Houston-based Nexalin Technology’s proprietary neurostimulation device will move forward with a new clinical trial evaluating its treatment of anxiety disorders and chronic insomnia in Brazil.

The first of Nexalin’s Gen-2 15-milliamp neurostimulation devices have been shipped to São Paulo, Brazil, and the study will be conducted at the Instituto de Psiquiatria university hospital (IPq-HCFMUSP). The shipments aim to support the launch of a Phase II clinical trial in adult patients suffering from anxiety and insomnia, according to a news release.

“Brazil is an important emerging market for mental health innovation, and this collaboration marks our first IRB-approved study in the region,” Mike White, CEO of Nexalin, said in the release.

The study will be led by Dr. Andre Russowsky Brunoni, who specializes in neuromodulation and interventional psychiatry. He currently serves as director of the interventional psychiatry division at IPq-HCFMUSP and this summer will join UT Southwestern in Dallas and its Peter O’Donnell Jr. Brain Institute as a professor of psychiatry.

The Phase II study plans to enroll 30 adults in São Paulo and assess the efficacy of Nexalin’s non-invasive deep intracranial frequency stimulation (DIFS™) of the brain in reducing anxiety symptoms and improving sleep quality, according to the company. Using the Hamilton Anxiety Rating Scale (HAM-A), the trial’s goal is a reduction in anxiety symptoms, and assessments of sleep onset latency, total sleep time, overall sleep quality, depressive symptoms and clinical impression of improvement. The company plans to share results in a peer-reviewed scientific journal.

“Anxiety and insomnia are very common conditions that often occur together and cause significant distress,” Brunoni added in the news release. “In this study, we are testing a new, non-invasive brain stimulation technology that has shown promising results in recent research. Our goal is to offer a safe, painless, and accessible alternative to improve people’s well being and sleep quality.”

The Nexalin Gen-2 15-milliamp neurostimulation device has been approved in China, Brazil, and Oman.

The company also enrolled the first patients in its clinical trial at the University of California, San Diego, in collaboration with the VA San Diego Healthcare System for its Nexalin HALO, which looks to treat mild traumatic brain injury and post-traumatic stress disorder in military personnel and the civilian population.

Two Rice University undergraduate engineering students have developed a non-invasive vibrotactile glove that aims to alleviate the symptoms of Parkinson’s disease through therapeutic vibrations. Emmie Casey and Tomi Kuye developed the project with support from the Oshman Engineering Design Kitchen (OEDK).

Based on research from the Peter Tass Lab at Stanford University, the Rice team set out to replicate the breakthrough technology at a lower cost. They are working to develop a commercial version of the glove priced at $250 and are taking preorders now, with hopes to deliver 500 gloves this fall. Read more.

A team of researchers at the University of Houston led by professor Mim Rahimi has made two breakthroughs in addressing climate change and potentially reducing the cost of capturing harmful emissions from power plants.

The first introduces a membraneless electrochemical process that cuts energy requirements and costs for amine-based carbon dioxide capture during the acid gas sweetening process. The second demonstrates a vanadium redox flow system capable of both capturing carbon and storing renewable energy.

“From membraneless systems to scalable flow systems, we’re charting pathways to decarbonize hard-to-abate sectors and support the transition to a low-carbon economy,” Rahimi said. Read more.

Houston scientists create platform for long-lasting, precise drug delivery

drug breakthrough

A team of Rice University scientists has developed a new drug delivery platform that researchers say can slow the rate of drug release, which has major implications for drug efficacy and potentially cancer immunotherapy.

The research was published in Nature Nanotechnology, and supported by the National Science Foundation, the National Institutes of Health, the Cancer Prevention and Research Institute of Texas and the Welch Foundation.

In the study, the team demonstrated how a peptide hydrogel functions as a three-dimensional network that controls the rate of release across a range of medication types, including small-molecule drugs and biologics such as insulin and antibodies. The system, called self-assembling boronate ester release (SABER), uses reversible chemical bonds between the peptide and the drug molecule to extend the duration of drug release. Instead of passing quickly through the net, the drug gets temporarily “stuck” each time it binds to the peptide, which slows its passage out of the hydrogel, according to Rice.

The researchers formulated a tuberculosis-treating drug into a hydrogel. They used it to treat infected mice with a single injection of the drug-laden hydrogel. In the test, the hydrogel outperformed almost daily oral administration of the medication over two weeks. Insulin packaged in SABER hydrogels successfully controlled blood sugar levels in diabetic mice for six days in another set of experiments.

Brett Pogostin, a Rice doctoral alum who led the development of SABER and served as first author of the study, began working on self-assembling peptides as an undergraduate student at Rice. Jeffrey Hartgerink, a professor of chemistry and bioengineering at Rice, and Kevin McHugh, associate professor of bioengineering and chemistry and a Cancer Prevention and Research Institute of Texas scholar, advised Pogostin and served as corresponding authors on the study.

Pogostin’s work aimed to bridge foundational materials research and biomedical applications. SABER was inspired by a drug delivery course taught by McHugh, where Pogostin learned about dynamic covalent bonds used in glucose sensing, where the bonds reversibly form and break apart. That quality inspired Pogostin to adapt the concept for drug delivery.

“Brett really drove this project in a way that is, in my experience, unusual for a graduate student,” Hartgerink said in the news release. “It’s a very versatile approach. You can make both small-molecule drugs and very large biologics sticky with the type of chemistry that Brett developed.”

The team demonstrated the platform in two different use cases with Tuberculosis and Type 1 diabetes, with SABER simplifying dosing and enhancing the efficacy of the drugs. Hartgerink described the current SABER system as “generation one,” and plans to work to make it widely applicable. He is looking into how SABER could be applied to cancer immunotherapy.

“What I’m really passionate about right now is cancer prevention — trying to think about how we can use materials to prime the immune system to prevent cancer from ever happening as opposed to just treating it,” Pogostin added.

10 Houston companies clock in with best corporate cultures, says Forbes

Where to Work

Two of Houston's biggest medical institutions – Houston Methodist and MD Anderson Cancer Center – have just landed top-50 spots on Forbes' new ranking of "America's Best Employers for Company Culture." The report highlighted eight more Houston-area companies for their inspiring company culture.

Forbes partnered with market research firm Statista to survey over 218,000 workers at companies with at least 1,000 employees throughout the U.S, and relied on data from the past three years of employee surveys (with an emphasis on the most recent data and recommendations from current employees). Companies don't pay to be included, Forbes additionally noted.

Among the final list of 600 U.S. companies, 30 Texas employers were praised for providing "a unifying company culture that inspires a sense of purpose and loyalty among employees."

Houston Methodist climbed into the No. 15 spot nationally and outranked all other Texas companies on the list, while MD Anderson ranked 47th nationwide. Both institutions have dominated U.S. News' annual rankings of the best Texas hospitals for over a decade, proving exactly how having a great company culture can also improve the service provided to patients.

According to the report's research, employers with a successful company culture don't rely on "surface-level perks" such as free lunches, wellness apps, and flex days to inspire employee engagement. Instead, employers that focused on conflict resolution and coaching their managers saw a reduction in employee burnout and an increase in "perceptions of fairness and leadership care."

"In fact, the researchers noted that when 'senior leaders changed how they led — how they ran meetings, gave feedback, made decisions and responded to challenge — trust scores rose by an average of 26 percent,'" the report said.

The eight other Houston-area companies that earned national acclaim for their company culture are:

  • No. 220 – Stewart Info Services
  • No. 325 – BP
  • No. 332 – Baylor College of Medicine
  • No. 492 – Chevron Phillips Chemical, The Woodlands
  • No. 525 – Insperity
  • No. 558 – NRG Energy
  • No. 586 – Waste Management
  • No. 593 – LyondellBassell

Other Texas employers with great company culture:
