Houston researchers are part of a team that has created an AI model intended to understand how brain activity relates to behavior and illness.

Scientists from Baylor College of Medicine worked with peers from Yale University, University of Southern California and Idaho State University to make Brain Language Model, or BrainLM. Their research was published as a conference paper at ICLR 2024, a meeting of some of deep learning’s greatest minds.

“For a long time we’ve known that brain activity is related to a person’s behavior and to a lot of illnesses like seizures or Parkinson’s,” Dr. Chadi Abdallah, associate professor in the Menninger Department of Psychiatry and Behavioral Sciences at Baylor and co-corresponding author of the paper, says in a press release. “Functional brain imaging or functional MRIs allow us to look at brain activity throughout the brain, but we previously couldn’t fully capture the dynamic of these activities in time and space using traditional data analytical tools.

"More recently, people started using machine learning to capture the brain complexity and how it relates it to specific illnesses, but that turned out to require enrolling and fully examining thousands of patients with a particular behavior or illness, a very expensive process,” Abdallah continues.

Using 80,000 brain scans, the team was able to train their model to figure out how brain activities related to one another. Over time, this created the BrainLM brain activity foundational model. BrainLM is now well-trained enough to use to fine-tune a specific task and to ask questions in other studies.

Abdallah said that using BrainLM will cut costs significantly for scientists developing treatments for brain disorders. In clinical trials, it can cost “hundreds of millions of dollars,” he said, to enroll numerous patients and treat them over a significant time period. By using BrainLM, researchers can enroll half the subjects because the AI can select the individuals most likely to benefit.

The team found that BrainLM performed successfully in many different samples. That included predicting depression, anxiety and PTSD severity better than other machine learning tools that do not use generative AI.

“We found that BrainLM is performing very well. It is predicting brain activity in a new sample that was hidden from it during the training as well as doing well with data from new scanners and new population,” Abdallah says. “These impressive results were achieved with scans from 40,000 subjects. We are now working on considerably increasing the training dataset. The stronger the model we can build, the more we can do to assist with patient care, such as developing new treatment for mental illnesses or guiding neurosurgery for seizures or DBS.”

For those suffering from neurological and mental health disorders, BrainLM could be a key to unlocking treatments that will make a life-changing difference.

Houston artificial intelligence startup raises $6M in seed funding

money moves

A computer science professor at Rice University has raised seed funding last month in order to grow his company that's focused on democratizing artificial intelligence tools.

ThirdAI, founded by Anshumali Shrivastava in April, raised $6 million in a seed funding round from three California-based VCs — Neotribe Ventures and Cervin Ventures, which co-led the round with support from Firebolt Ventures.

Shrivastava, CEO, co-founded the company with Tharun Medini, a recent Ph.D. who graduated under Shrivastava from Rice's Department of Electrical and Computer Engineering. Medini serves as the CTO of ThirdAI — pronounced "third eye." The startup is building the next generation of scalable and sustainable AI tools and deep learning systems.

"We are democratizing artificial intelligence through software innovations," says Shrivastava in a news release from Rice. "Our innovation would not only benefit current AI training by shifting to lower-cost CPUs, but it should also allow the 'unlocking' of AI training workloads on GPUs that were not previously feasible."

The technology ThirdAI is working with comes from 10 years of deep learning research and innovation. The company's technology has the potential to make computing 15-times faster.

"ThirdAI has developed a breakthrough approach to train deep learning models with a large number of parameters that run efficiently on general purpose CPUs. This technology has the potential to result in a gigantic leap forward in the accuracy of deep learning models," per and announcement from Cervin Ventures. "Our investment in ThirdAI was a no-brainer and we are fortunate to have had the opportunity to invest."

Houston climatetech startup raises $21.5M series A to grow robotics solution

seeing green

A Houston energy tech startup has raised a $21.5 million series a round of funding to support the advancement of its automated technology that converts field wastes into stable carbon.

Applied Carbon, previously known as Climate Robotics, announced that its fresh round of funding was led by TO VC, with participation from Congruent Ventures, Grantham Foundation, Microsoft Climate Innovation Fund, S2G Ventures, Overture.vc, Wireframe Ventures, Autodesk Foundation, Anglo American, Susquehanna Foundation, US Endowment for Forestry and Communities, TELUS Pollinator Fund for Good, and Elemental Excelerator.

The series A funding will support the deployment of its biochar machines across Texas, Oklahoma, Arkansas, and Louisiana.

"Multiple independent studies indicate that converting crop waste into biochar has the potential to remove gigatons of CO2 from the atmosphere each year, while creating trillions of dollars in value for the world's farmers," Jason Aramburu, co-founder and CEO of Applied Carbon, says in a news release. "However, there is no commercially available technology to convert these wastes at low cost.

"Applied Carbon's patented in-field biochar production system is the first solution that can convert crop waste into biochar at a scale and a cost that makes sense for broad acre farming," he continues.

Applied Carbon rebranded in June shortly after being named a top 20 finalist in XPRIZE's four-year, $100 million global Carbon Removal Competition. The company also was named a semi-finalist and awarded $50,000 from the Department of Energy's Carbon Dioxide Removal Purchase Pilot Prize program in May.

"Up to one-third of excess CO2 that has accumulated in the atmosphere since the start of human civilization has come from humans disturbing soil through agriculture," Joshua Phitoussi, co-founder and managing partner at TO VC, adds. "To reach our net-zero objectives, we need to put that carbon back where it belongs.

"Biochar is unique in its potential to do so at a permanence and price point that are conducive to mass-scale adoption of carbon dioxide removal solutions, while also leaving farmers and consumers better off thanks to better soil health and nutrition," he continues. "Thanks to its technology and business model, Applied Carbon is the only company that turns that potential into reality."

The company's robotic technology works in field, picking up agricultural crop residue following harvesting and converts it into biochar in a single pass. The benefits included increasing soil health, improving agronomic productivity, and reducing lime and fertilizer requirements, while also providing a carbon removal and storage solution.

"We've been looking at the biochar sector for over a decade and Applied Carbon's in-field proposition is incredibly compelling," adds Joshua Posamentier, co-founder and managing partner of Congruent Ventures. "The two most exciting things about this approach are that it profitably swings the agricultural sector from carbon positive to carbon negative and that it can get to world-scale impact, on a meaningful timeline, while saving farmers money."

Rice University makes top 5 lists of best biz schools in the country

top ranking

MBA programs at Rice University’s Jones Graduate School of Business have landed two top five rankings in The Princeton Review’s annual list of the country’s best business schools.

Rice earned a No. 4 ranking for its online MBA program and a No. 5 ranking for its MBA program in finance.

“These rankings are indicative of the high-quality education offered through all of our MBA programs. Students studying finance at Rice … are taught by faculty whose research and expertise enhances core classes and hard skills, so students are not just prepared to be successful in their careers, but they are also prepared to think critically about their roles and to lead in their industry,” Peter Rodriguez, dean of the Jones Graduate School of Business, says in a news release.

“These rankings are also indicative of our broader approach: offering students flexibility in their pursuit of an MBA, while retaining the experience of studying with world-class faculty — no matter what program they choose,” Rodriguez adds.

Rice also achieved high rankings in two other MBA categories: No. 8 for “greatest resources for women” and No. 10 for “greatest resources for minority students.”

The Princeton Review’s 2024 business school rankings are based on data from surveys of administrators at more than 400 business schools as well as surveys of 32,200 students enrolled in the schools’ MBA programs.

“The schools that made our list for 2024 all have impressive individual distinctions,” Rob Franek, The Princeton Review’s editor-in-chief, says in a news release. “What they share are three characteristics that broadly informed our criteria for these rankings: outstanding academics, robust experiential learning components and excellent career services.”

Rice also ranks as the top school for graduate entrepreneurship programs, which Princeton Review released last fall. The University of Houston ranks as No. 1 for undergraduate entrepreneurship programs.

When something is declared clean, one question invariably springs to mind: just how clean is clean?

Then it is, “What metrics decide what’s clean and what’s not?”

To answer those questions, one must abandon the subjective and delve into the scientific — and that’s where Clean Habits come in. The company has science on its side with Synbio, a patented cleaning formula that combines a unique blend of prebiotics and probiotics for their signature five-day clean.

“Actually, we are a synbiotic, which is a prebiotic and a probiotic fused together,” says Kristy Phillips, founder and CEO of Clean Habits. “And that's what gives us the five-day clean, and we also have the longest shelf life — three years — of any probiotic on the market.” Read more.

A University of Houston professor of electrical and computer engineering, Jiming Bao, is improving thermal imaging and infrared thermography with a new method to measure the continuous spectrum of light.

His innovative method involves techniques that will be used to measure and visualize temperature distributions without direct contact with the subject being photographed, according to the university. The challenges generally faced by conventional thermal imaging is addressed, as the new study hopes to eliminate temperature dependence, and wavelength.

“We designed a technique using a near-infrared spectrometer to measure the continuous spectrum and fit it using the ideal blackbody radiation formula,” Bao tells the journal Device. “This technique includes a simple calibration step to eliminate temperature- and wavelength-dependent emissivity.” Read more.
