Houston has a lot of the right ingredients for commercialization and scaling up companies, so when Zach Ellis moved to town to stand up a venture capital firm that made investments in diverse founders, he decided to go about it in an innovative way.

South Loop Ventures, which Ellis launched two years ago, invests in pre-seed and seed-stage startups across health care, climatetech, aerospace, sports, and fintech. While the first handful of investments, which have already been made, are into Houston-based companies, Ellis explains on the Houston Innovators Podcast that the firm plans to invest in promising companies from across the country and bring them into Houston's ecosystem to grow and scale.

"Any investor wants to feel like they are looking at the best possible investment opportunities in which to deploy capital," Ellis says on the show. "So that's reason No. 1 to cast your net as widely as possible.

"At the same time, you want to give any investment that you make greatest chances of success," he continues. "The biggest factor of success outside of the team and the capital you give them, is the customers that they can call upon. In bringing targeted companies to Houston or connecting them with Houston, you introduce the opportunity for them to achieve rapid scale and work with world-class partners very efficiently."

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.”

Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced last year, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its second Houston cohort this summer.

This year, the incubator grew to include its largest number of concurrent supported fellows, with 88 companies currently being supported nationally. In total, Activate has supported 296 fellows who have created 236 companies. Those companies have raised over $4 billion in follow-on funding, according to Activate. In Houston, it has supported several Innovation Awards finalists, including Solidec, Bairitone Health and Deep Anchor Solutions. It is led locally by Houston Managing Director Jeremy Pitts.

EnergyTech Nexus

Cleantech startup hub EnergyTech Nexus' mission is to accelerate the energy transition by connecting founders, investors and industrial stakeholders and helping to develop transformative companies, known as "thunderlizards."

The hub was founded in 2023 by CEO Jason Ethier, Juliana Garaizar and Nada Ahmed. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, EarthEn Energy and Solidec—many of which are current or past Innovation Awards finalists. This year Energy Tech Nexus launched its COPILOT Accelerator, powered by Wells Fargo Innovation Incubator (IN²) at the National Renewable Energy Laboratory (NREL). COPILOT partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. Energy Tech Nexus also launched its Liftoff fundraising program, its Investor Program, and a "strategic ecosystem partnership" with Greentown Labs.

Greentown Labs

Climatetech incubator Greentown Labs offers its community resources and a network to climate and energy innovation startups looking to grow. The collaborative community offers members state-of-the-art prototyping labs, business resources and access to investors and corporate partners. The co-located incubator was first launched in Boston in 2011 before opening in Houston in 2021.

Greentown has seen major changes and activity this year. In February, Greentown announced Georgina Campbell Flatter as its new CEO, along with a new Board of Directors. In July, it announced Lawson Gow as its Head of Houston, a "dedicated role to champion the success of Greentown Houston’s startups and lead Greentown’s next chapter of impact in the region," according to Greentown. It has since announced numerous new partnerships, including those with Energy Tech Nexus, Los Angeles-based software development firm Nominal, to launch the new Industrial Center of Excellence; and Houston-based Shoreless, to launch an AI lab onsite. Greentown Houston has supported 175 startups since its launch in 2021, with 45 joining in the last two years. Those startups include the likes of Hertha Metals, RepAir Carbon, Solidec, Eclipse Energy (formerly GoldH2) and many others.

Rice University launches  engineering-led brain science and health institute

brain research

Rice University has announced the creation of a new interdisciplinary center known as the Rice Brain Institute (RBI).

The new hub will aim to use engineering, natural sciences and social sciences to research the brain and reduce the burden of neurodegenerative, neurodevelopmental and mental health disorders.

“The Rice Brain Institute reflects Rice’s strength in collaboration without boundaries,” Rachel Kimbro, dean of the School of Social Sciences, said in a news release. “Our researchers are not only advancing fundamental science but they’re also ensuring that knowledge reaches society in ways that promote human flourishing.”

RBI researchers will work in thematic clusters focusing on neurodegeneration, mental health, brain injury and neurodevelopment. The clusters will work toward goals such as significantly improving key brain health outcomes, reducing mortality and mental health disorders and improving quality of life for patients living with brain injuries and neurodevelopmental disorders, according to Rice.

The institute will focus on “engineering-driven innovation,” rather than traditional neuroscience, to design tools that can measure, model and modulate brain activity based around Rice’s expertise in soft robotics, neuroimaging, data science and artificial intelligence—making it unique among peer organizations, according to Rice.

Additionally, RBI will be structured around three collaborative Rice “pillars”:

  • The Neuroengineering Initiative, launched in 2018, brings together neuroscience, engineering, and related fields experts
  • The Neuroscience Initiative, a new initiative that brings together cell biologists, neurobiologists, biochemists, chemists and physicists to explore fundamental mechanisms of the brain and nervous system
  • The Brain and Society Initiative, also a new initiative, considers brain research within the broader social and policy landscape

Rice’s Neuroengineering Initiative has already garnered more than $78 million in research funding, according to Rice, and has established major partnerships, like the Rice-Houston Methodist Center for Neural Systems Restoration.

“Rice is uniquely equipped to bridge and connect scientific understanding of the brain and behavior sciences with the technologies and policies that shape our world,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, added in the news release. “By uniting faculty in neuroengineering, neuroscience and psychological sciences, this interdisciplinary hub embodies the kind of bold, nimble collaboration that allows Rice to turn discovery into societal impact to save lives and enhance human flourishing.”

The formation of the RBI coincides with recent support of the Dementia Prevention Research Institute of Texas (DPRIT), which landed voter approval earlier this week and aims to make Texas the center for dementia research via brain-health tech. According to the World Economic Forum, brain disorders and mental health disorders cost the global economy an estimated $5 trillion per year and could be as high as $16 trillion by 2030.

“Few areas of research have as direct and profound an impact on human well-being as brain health,” Rice President Reginald DesRoches added in the news release. “As rates of Alzheimer’s, dementia and other neurological diseases rise in our country and around the world, universities have a responsibility to lead the discovery of solutions that preserve memory, movement and quality of life. We all know someone who has been affected by a brain-related health issue, so this research is personal to all of us.”
