Kirsten Siebach is getting ready for her Mars mission — one that keeps her firmly planted on Earth, but will allow her to search for ancient microbial life on the Red Planet nonetheless. The Rice University professor has again been selected by NASA to join a research team overseeing a rover that is currently en route to Mars.

"Because there is only one rover, the whole team at NASA has to agree about what to look at, or analyze, or where to drive on any given day," Siebach says in the release. "None of the rovers' actions are unilateral decisions. But it is a privilege to be part of the discussion and to get to argue for observations of rocks that will be important to our understanding of Mars for decades." Read more.

Mike Francis wants to fireproof the state of California. It's a lofty goal, but he has the means. His company, NanoTech Inc., has an innovative product that can insulate and fireproof materials, and, buoyed by a $5 million seed round, he's well on his way to being able to slowly but surely fireproof existing infrastructure in the West Coast.

"We're working with all of the major players in the state of California to not only fireproof the utility infrastructure, but eventually homes and businesses," Francis says on last week's episode of the Houston Innovators Podcast. "Our goal, if we're looking into the future, is to fireproof that state — and we're working with the right people and companies to make it happen." Read more and listen to the podcast.

Nowadays, consumers care about where their products come from — and if they exist due to a humanitarian or sustainable supply chain — and the onus is on businesses to increase transparency. That's where Topl, a Houston-based blockchain company, and its new partner Trackz, a Denver-based supply chain software company, come in.

"Topl and TrackX's solution will be a great option for companies having to comply with new regulations and compliance mandates," says Kim Raath, CEO of Topl. "Further, our joint solution allows users to visualize their supply chain data, monitor suppliers, and easily report the progress of ESG initiatives to all stakeholders."

A Rice University Martian geologist has been chosen by NASA as one of the 13 scientists who will be working on a new Mars rover.

Perseverance, the rover that launched in July and is expected to land on Mars in February. It will be scouting for samples to bring back to study for ancient microbial life, and Kirsten Siebach — an assistant professor of Earth, Environmental and Planetary Sciences — will be among the researchers to work on the project. Her proposal was one of 119 submitted to NASA for funding, according to a Rice press release.

"Everybody selected to be on the team is expected to put some time into general operations as well as accomplishing their own research," she says in the release. "My co-investigators here at Rice and I will do research to understand the origin of the rocks Perseverance observes, and I will also participate in operating the rover."

Perseverance is headed for Jezero Crater, a 28-mile-wide area that once hosted a lake and river delta where, according to scientists, microbial life may have existed over 3 billion years ago. Siebach is particularly excited hopefully find fossils existing in atmospheric carbon dioxide dissolved in water — which usually exists as limestone on Earth.

"There are huge packages of limestone all over Earth, but for some reason it's extremely rare on Mars," she says. "This particular landing site includes one of the few orbital detections of carbonate and it appears to have a couple of different units including carbonates within this lake deposit. The carbonates will be a highlight of we're looking for, but we're interested in basically all types of minerals."

Siebach is familiar with rovers — she was a member of the team for NASA's Curiosity rover, which has been exploring Mars since 2012. For this new rover, Siebach knows what to expect.

"Because there is only one rover, the whole team at NASA has to agree about what to look at, or analyze, or where to drive on any given day," Siebach says in the release. "None of the rovers' actions are unilateral decisions. But it is a privilege to be part of the discussion and to get to argue for observations of rocks that will be important to our understanding of Mars for decades."

Siebach and her team — which includes Rice data scientist Yueyang Jiang and mineralogist Gelu Costin — are planning to tap into computational and machine-learning methods to map out minerals and discover evidence for former life on Mars. They will also be using a Planetary Instrument for X-ray Lithochemistry, or PIXL, to analyze the materials.

The return mission isn't expected to return until the early 2030s, so it's a long game for the scientists. However, the samples have the potential to revolutionize what we know about life on Mars with more context than before.

"Occasionally, something hits Mars hard enough to knock a meteorite out, and it lands on Earth," she says in the release. "We have a few of those. But we've never been able to select where a sample came from and to understand its geologic context. So these samples will be revolutionary."

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."

New Houston platform Same Day Reels launches for on-demand content creation

In The Moment

If an event doesn't happen on Instagram, did it even really happen? In today's social media-driven age of branding and audience engagement, the answer increasingly is no.

Houston entrepreneur Karen De Amat is looking to fill the online content creation needs of companies with her new venture, Same Day Reels, which launched in early August. It will serve as a platform to connect companies and brands with talent that can help turn an event into a viral moment as it is happening.

"Events move quickly, and social media moves even faster,” said De Amat. “Same Day Reels was built to help brands capture the moment while it still matters. We are creating a more efficient way for businesses and creators to work together. Brands need content faster, and creators need more opportunities to turn their talent into real work. Same Day Reels brings those needs together.”

The company is focused on adding livestreams and concurrent short video content to "activations, launches, fundraisers, grand openings, conferences, hospitality experiences, and private celebrations." Such content can significantly increase the visibility of a product or brand according to digital marketing brands like Wyzowl, whose data found 63 percent of people in 2026 prefer to learn about new products via short video.

Packages offered by Same Day Reels will include filming, editing, and publishing content within hours of the targeted event.

De Amat says that her content creation platform will be a way to preserve the excitement of events and launches by enshrining them with immediate social media-driven memories.

“Event content is no longer just something you post after the fact,” De Amat said. “It is part of how people experience, remember and share the moment.”

Previously, De Amat is also the founder and CEO of Social Behavior, an influencer marketing company she launched from her home in 2014. It quickly garnered an array of clients and thrust De Amat into the spotlight, including numerous appearances on Fox 26's The Isiah Factor. Influencer Marketing Hub named her one of the top CEOs of influencer marketing companies in Houston in 2025.
