Editor's note: This article has been updated to correct the total amount of investment and cash prizes awarded at the RBPC and with additional information from Rice.

Another team from the Great Lakes State took home top honors and investments at this year's Rice Business Plan Competition.

BRCĒ, a material-tech startup from Michigan State University, took home the top-place finish and the largest investment total at the annual Houston event. It has developed Lattice-Grip technology to create utility-based polymers that can replace traditional fabric. The materials are stronger, fire-resistant and more stable than traditional textiles, according to the company. Last year, the University of Michigan's Intero Biosystems won first-place finish and the largest investment total of $902,000.

In total, the RBPC doled out more than $1.4 million in investment and cash prizes, according to Rice. Over the three-day event, held April 9-11, the 42 competing startups presented their business plans to 300 angel, venture capital and corporate investors. Seven finalists were selected.

Three Texas teams, including one from Houston, were named among the finalists. Here's who won big this year, with their investment totals and some of their awards listed below.

big winners

Celebrating its 25th year, the Rice Alliance for Technology and Entrepreneurship hosted the celebrated Rice Business Plan Competition this month, doling out more than $2 million in investment and cash prizes to the top-performing teams.

“For 25 years, the Rice Business Plan Competition has helped shape how Rice Business shows up in the world by creating a platform where student-entrepreneurs can tackle some of the most complex challenges of our time in energy, in health care, in technology and beyond,” Peter Rodriguez, dean of Rice Business, the presenting sponsor of the event, said in a news release. “If we’re serious about changing the world — and I believe we are — then it’s our responsibility to open doors for students everywhere to imagine bold solutions and build what comes next.”

Over the course of the three-day event, the 42 startups competing this year from colleges or universities around the world presented their plans before more than 300 angel, venture capital, and corporate investors. The teams were selected from the event’s largest applicant pool to date and represented 34 universities across four countries, according to Rice. Winners were announced at the company showcase and awards ceremony April 12 in downtown Houston.

Seven finalists were selected, though each team left the competition with some form of funding, according to Rice. The University of Michigan's Intero Biosystems was the star of the show, bringing home both the top-place finish and the largest total investment.

Report: Where Texas ranks among best and worst states to live in 2026

Texas Talk

After earning its worst-ever ranking last year, Texas has improved slightly on an evaluation of the best states to live, but it's still at the bottom of the pack.

Each year, WalletHub's analysts compare all 50 states using 51 livability metrics to measure their affordability, economy, education and health, quality of life, and safety. Factors that were weighed include the cost of living, homeownership rates, population and income growth rates, wealth gaps, public school system quality, road quality, crime rates, and many others.

The Lone Star State landed at No. 36 in 2026, making it the 15th worth state to live right now. That's on par with its 2024 ranking, and it's a two-spot improvement over its 2025 performance.

While Texas residents can brag about living in a state with the No. 1 highest number of restaurants per capita and the 7th best quality of life in the country, that's about it. Texas earned middling-to-poor scores among the four remaining livability rankings: safety (No. 33), affordability (No. 35), economy (No. 37), and education and health (No. 40).

Here's how Texas fared in other nationwide rankings in the study:

  • No. 27 – Income Growth
  • No. 30 – Housing Costs
  • No. 39 – Percentage of Population in Poverty
  • No. 42 – Percentage of Adults in Fair or Poor Health
  • No. 46 – Homeownership Rate
  • No. 49 – Percentage of Population Aged 25 and Older with a High School Diploma or Higher
  • No. 48 – Average Weekly Work Hours
  • No. 50 – Percentage of Insured Population

Texas has a lot of work to do to improve its livability for all of its residents, but especially for women, according to several other 2026 WalletHub studies. Texas is the fourth-worst state for women, the ninth-worst state for working mothers, and the seventh-worst place to have a baby based on limited access to maternal and pediatric healthcare.

At the very bottom of the report is New Mexico, ranking 50th overall, with Louisiana (No. 49), Mississippi (No. 48), Alaska (No. 47), and Arkansas (No. 46) rounding out the bottom five.

After holding on as the No. 1 best state to live for a few years in a row, Massachusetts now ranks No. 4 and was overtaken by Idaho (No. 1), New Jersey (No. 2), and Wisconsin (No. 3). New Hampshire rounds out the top five best states to live.

WalletHub's top 10 best states to live in 2026 are:

  • No. 1 – Idaho
  • No. 2 – New Jersey
  • No. 3 – Wisconsin
  • No. 4 – Massachusetts
  • No. 5 – New Hampshire
  • No. 6 – Wyoming
  • No. 7 – Utah
  • No. 8 – Minnesota
  • No. 9 – Pennsylvania
  • No. 10 – Florida

The startup expects more equity and debt deals to close “imminently.” Quaise has raised $230 million since its founding in 2018. Continue reading.

Houston researchers develop dissolvable implant for targeted cancer drug delivery

cancer research

Researchers at Houston Methodist have developed a biodegradable implant that can be used to safely and consistently deliver drug treatments to tumors and then dissolve without the need for further surgery.

The implant is only the size of a grain of rice, but its potential is staggering. The biodegradable nanofibrous drug-eluting seed (b-NDES) works as a reservoir parked inside a soft tumor, where it can slowly release immune-stimulating drugs over time. This overcomes a consistent problem with drugs such as immune checkpoint inhibitors. Normal systemic administration sees comparatively little of the drug making its way to the tumor, with most of it circulating throughout the body. The b-NDES is like deploying a small guerrilla fighting force embedded in enemy territory, doing maximum damage to the entrenched tumor.

"To improve cancer treatment, we're trying to start a fire inside the tumor itself," Corrine Chua, associate professor in the Center for BioNanoengineering at Houston Methodist Research Institute, said in a news release. "By activating immune cells directly within the tumor microenvironment, those cells can then travel throughout the body and seek out cancer wherever it exists. The b-NDES platform was developed to help keep therapeutic drugs concentrated inside tumors while minimizing exposure to healthy tissues.”

Chua co-led the study with Alessandro Grattoni, chair and director of the Center for BioNanoengineering at Houston Methodist Research Institute.

The study included support from the Nancy Owens Breast Cancer Foundation and the National Institutes of Health/National Cancer Institute.

Chau and Grattoni used preclinical models of triple-negative breast cancer, an aggressive form of cancer that is estrogen receptor-negative, progesterone receptor-negative and HER2-negative. Because of the receptor negativity, some popular treatments like tamoxifen and trastuzumab are ineffective. Chemotherapy has been shown to be the best course of action.

The b-NDES implant is deployed alongside radiation drugs. It keeps the drugs focused on the tumor, reducing the amount of harmful side effects typically seen when drugs are circulated more widely in the body. In 60 percent of the models, tumors were eliminated and did not cause side effects beyond the tumor site. Once the drugs have been deployed, the implant breaks down naturally.

While promising, more research will have to be done to expand use to other tumor types.

"Although the study focused on triple-negative breast cancer models, the approach could have broader applications for solid tumors," Grattoni added in the release. "It could potentially be used in cancers where there is a tumor lesion accessible for placement, including pancreatic or lung cancers."
