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 suburb ranks as No. 3 best place to retire in Texas

Rankings & Reports

Texas retirees on the hunt for the right place to settle down and enjoy their blissful retirement years will find their haven in the Houston suburb of Pasadena, which just ranked as the third-best city to retire statewide.

A new study conducted by the research team at RetirementLiving.com, "The Best Cities to Retire in Texas," compared the affordability, safety, livability, and healthcare access for seniors across 31 Texas cities with at least 90,000 residents.

Wichita Falls, about 140 miles northwest of Dallas, claimed the top spot as the No. 1 best place to retire in Texas.

The senior living experts said Pasadena has the best healthcare access for seniors in the entire state, and it ranked as the No. 8 most affordable city on the list.

"Taking care of one’s health can be stressful for seniors," the report said. "Harris County, where [Pasadena is] located, has 281.1 primary care physicians per 1,000 seniors — that’s almost 50-fold the statewide ratio of 5.9 per 1,000."

Pasadena ranked 10th overall for its livability, and ranked 25th for safety, the report added.

Meanwhile, Houston proper ranked as the No. 31 best place to retire in Texas, but its livability score was the 7th best statewide.

Seven of the Lone Star State's top 10 best retirement locales are located in the Dallas-Fort Worth Metroplex: Carrollton (No. 2), Plano (No. 4), Garland (No. 5), Richardson (No. 6), Arlington (No. 7), Grand Prairie (No. 8), and Irving (No. 9). McAllen, a South Texas border town, rounded out the top 10.

RetirementLiving said Carrollton has one of the lowest property and violent crime rates per capita in Texas, and it ranked as the No. 5 safest city on the list. About 17 percent of the city's population is aged 65 or older, which is higher than the statewide average of just 14 percent.

The top 10 best place to retire in Texas in 2026 are:

  • No. 1 – Wichita Falls
  • No. 2 – Carrollton
  • No. 3 – Pasadena
  • No. 4 – Plano
  • No. 5 – Garland
  • No. 6 – Richardson
  • No. 7 – Arlington
  • No. 8 – Grand Prairie
  • No. 9 – Irving
  • No. 10 – McAllen

Rice University lands $18M to revolutionize lymphatic disease detection

fresh funding

An arm of the U.S. Department of Health and Human Services has awarded $18 million to scientists at Rice University for research that has the potential to revolutionize how lymphatic diseases are detected and help increase survivability.

The lymphatic system is the network of vessels all over the body that help eliminate waste, absorb fat and maintain fluid balance. Diseases in this system are often difficult to detect early due to the small size of the vessels and the invasiveness of biopsy testing. Though survival rates of lymph disease have skyrocketed in the United States over the last five years, it still claims around 200,000 people in the country annually.

Early detection of complex lymphatic anomalies (CLAs) and lymphedema is essential in increasing successful treatment rates. That’s where Rice University’s SynthX Center, directed by Han Xiao and Lei Li, an assistant professor of electrical and computer engineering, comes in.

Aided by researchers from Texas Children’s Hospital, Baylor College of Medicine, the University of Texas at Dallas and the University of Texas Southwestern Medical Center, the center is pioneering two technologies: the Visual Imaging System for Tracing and Analyzing Lymphatics with Photoacoustics (VISTA-LYMPH) and Digital Plasmonic Nanobubble Detection for Protein (DIAMOND-P).

Simply put, VISTA-LYMPH uses photoacoustic tomography (PAT), a combination of light and sound, to more accurately map the tiny vessels of the lymphatic system. The process is more effective than diagnostic tools that use only light or sound, independent of one another. The research award is through the Advanced Research Projects Agency for Health (ARPA-H) Lymphatic Imaging, Genomics and pHenotyping Technologies (LIGHT) program, part of the U.S. HHS, which saw the potential of VISTA-LYMPH in animal tests that produced finely detailed diagnostic maps.

“Thanks to ARPA-H’s award, we will build the most advanced PAT system to image the body’s lymphatic network with unprecedented resolution and speed, enabling earlier and more accurate diagnosis,” Li said in a news release.

Meanwhile, DIAMOND-P could replace the older, less exact immunoassay. It uses laser-heated vapors of plasmonic nanoparticles to detect viruses without having to separate or amplify, and at room temperature, greatly simplifying the process. This is an important part of greater diagnosis because even with VISTA-LYMPH’s greater imaging accuracy, many lymphatic diseases still do not appear. Detecting biological markers is still necessary.

According to Rice, the efforts will help address lymphatic disorders, including Gorham-Stout disease, kaposiform lymphangiomatosis and generalized lymphatic anomaly. They also could help manage conditions associated with lymphatic dysfunction, including cancer metastasis, cardiovascular disease and neurodegeneration.

“By validating VISTA-LYMPH and DIAMOND-P in both preclinical and clinical settings, the team aims to establish a comprehensive diagnostic pipeline for lymphatic diseases and potentially beyond,” Xiao added in the release.

The ARPA-H award funds the project for up to five years.
