Rice University chemist Han Xiao, who also serves as director of the university’s Synthesis X Center, and cancer biologist Dihua Yu of The University of Texas MD Anderson Cancer Center have received a three-year, $1.5 million grant from the Robert J. Kleberg Jr. and Helen C. Kleberg Foundation.

The funding will allow them to continue their research on treating brain metastasis by overcoming the blood-brain barrier, or the BBB, according to a news release.

Brain metastasis is the leading form of brain cancer, with survival rates below 20 percent within a year of diagnosis, according to the National Library of Medicine. It commonly originates from breast, lung and melanoma cancers.

The BBB typically acts as a protective barrier for the brain. However, it prevents most drugs from being able to directly reach the brain. According to Rice, only 2 percent of FDA-approved small molecule drugs can penetrate the BBB, limiting treatment options.

Xiao and Yu’s approach to dealing with the BBB includes a light-induced brain delivery (LIBD) platform. The advanced system employs nanoparticles that are embedded with a near-infrared dye for the transport of therapeutic agents across the BBB. The research will evaluate the LIBD’s ability to improve the delivery of small-molecule drugs and biological therapies. Some therapies have shown potential for reducing cancer growth in laboratory studies, but they have struggled due to limited BBB penetration in animal models.

“Our LIBD platform represents a novel strategy for delivering drugs to the brain with precision and efficiency,” Xiao said in a news release. “This technology could not only improve outcomes for brain metastasis patients but also pave the way for treating other neurological diseases.”

The Kleberg Foundation looks for groundbreaking medical research proposals from leading institutions that focus on “innovative basic and applied biological research that advances scientific knowledge and human health” according to the foundation.

“This research is a testament to the power of collaboration and innovation,” Xiao said in a news release. “Together, we’re pushing the boundaries of what’s possible in treating brain metastasis and beyond.”

Rice launched the Synthesis X Center, or Synth X, last spring. It was born out of what started about eight years ago as informal meetings between Xiao's research group and others from the Baylor College of Medicine’s Dan L Duncan Comprehensive Cancer Center. It aims to turn fundamental research into clinical applications through collaboration.

“This collaboration builds on the strengths of both research teams,” Xiao said in the release. “By combining SynthX Center's expertise in chemistry with Dr. Yu's expertise in cancer biology and brain metastases, we aim to create a transformative solution.”

future of cellular health

A Rice University chemist has landed a $2 million grant from the National Institute of Health for his work that aims to reprogram the genetic code and explore the role certain cells play in causing diseases like cancer and neurological disorders.

The funds were awarded to Han Xiao, the Norman Hackerman-Welch Young Investigator, associate professor of chemistry, from the NIH's Maximizing Investigators’ Research Award (MIRA) program, which supports medically focused laboratories.

Xiao will use the five-year grant to develop noncanonical amino acids (ncAAs) with diverse properties to help build proteins, according to a statement from Rice. He and his team will then use the ncAAs to explore the vivo sensors for enzymes involved in posttranslational modifications (PTMs), which play a role in the development of cancers and neurological disorders. Additionally, the team will look to develop a way to detect these enzymes in living organisms in real-time rather than in a lab.

“This innovative approach could revolutionize how we understand and control cellular functions,” Xiao said in the statement.

According to Rice, these developments could have major implications for the way diseases are treated, specifically for epigenetic inhibitors that are used to treat cancer.

Xiao helped lead the charge to launch Rice's new Synthesis X Center this spring. The center, which was born out of informal meetings between Xio's lab and others from the Baylor College of Medicine’s Dan L Duncan Comprehensive Cancer Center at the Baylor College of Medicine, aims to improve cancer outcomes by turning fundamental research into clinical applications.

They will build upon annual retreats, in which investigators can share unpublished findings, and also plan to host a national conference, the first slated for this fall titled "Synthetic Innovations Towards a Cure for Cancer.”

Houston organizations launch collaborative center to boost cancer outcomes

new to HOU

Rice University's new Synthesis X Center officially launched last month to bring together experts in cancer care and chemistry.

The center was born out of what started about seven years ago as informal meetings between Rice chemist Han Xiao's research group and others from the Baylor College of Medicine’s Dan L Duncan Comprehensive Cancer Center at the Baylor College of Medicine. The level of collaboration between the two teams has grown significantly over the years, and monthly meetings now draw about 100 participants from across disciplines, fields and Houston-based organizations, according to a statement from Rice.

Researchers at the new SynthX Center will aim to turn fundamental research into clinical applications and make precision adjustments to drug properties and molecules. It will focus on improving cancer outcomes by looking at an array of factors, including prevention and detection, immunotherapies, the use of artificial intelligence to speed drug discovery and development, and several other topics.

"At Rice, we are strong on the fundamental side of research in organic chemistry, chemical biology, bioengineering and nanomaterials,” Xiao says in the statement. “Starting at the laboratory bench, we can synthesize therapeutic molecules and proteins with atom-level precision, offering immense potential for real-world applications at the bedside ... But the clinicians and fundamental researchers don’t have a lot of time to talk and to exchange ideas, so SynthX wants to serve as the bridge and help make these connections.”

SynthX plans to issue its first merit-based seed grants to teams with representatives from Baylor and Rice this month.

With this recognition from Rice, the teams from Xiao's lab and the TMC will also be able to expand and formalize their programs. They will build upon annual retreats, in which investigators can share unpublished findings, and also plan to host a national conference, the first slated for this fall titled "Synthetic Innovations Towards a Cure for Cancer.”

“I am confident that the SynthX Center will be a great resource for both students and faculty who seek to translate discoveries from fundamental chemical research into medical applications that improve people’s lives,” Thomas Killian, dean of the Wiess School of Natural Sciences, says in the release.

Rice announced that it had invested in four other research centers along with SynthX last month. The other centers include the Center for Coastal Futures and Adaptive Resilience, the Center for Environmental Studies, the Center for Latin American and Latinx Studies and the Rice Center for Nanoscale Imaging Sciences.

Earlier this year, Rice also announced its first-ever recipients of its One Small Step Grant program, funded by its Office of Innovation. The program will provide funding to faculty working on "promising projects with commercial potential," according to the website.

Houston lab develops AI tool to improve neurodevelopmental diagnoses

developing news

One of the hardest parts of any medical condition is waiting for answers. Speeding up an accurate diagnosis can be a doctor’s greatest mercy to a family. A team at Baylor College of Medicine has created technology that may do exactly that.

Led by Dr. Ryan S. Dhindsa, assistant professor of pathology and immunology at Baylor and principal investigator at the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital, the scientists have developed an artificial intelligence-based approach that will help doctors to identify genes tied to neurodevelopmental disorders. Their research was recently published the American Journal of Human Genetics.

According to its website, Dhindsa Lab uses “human genomics, human stem cell models, and computational biology to advance precision medicine.” The diagnoses that stem from the new computational tool could include specific types of autism spectrum disorder, epilepsy and developmental delay, disorders that often don’t come with a genetic diagnosis.

“Although researchers have made major strides identifying different genes associated with neurodevelopmental disorders, many patients with these conditions still do not receive a genetic diagnosis, indicating that there are many more genes waiting to be discovered,” Dhindsa said in a news release.

Typically, scientists must sequence the genes of many people with a diagnosis, as well as people not affected by the disorder, to find new genes associated with a particular disease or disorder. That takes time, money, and a little bit of luck. AI minimizes the need for all three, explains Dhindsa: “We used AI to find patterns among genes already linked to neurodevelopmental diseases and predict additional genes that might also be involved in these disorders.”

The models, made using patterns expressed at the single-cell level, are augmented with north of 300 additional biological features, including data on how intolerant genes are to mutations, whether they interact with other known disease-associated genes, and their functional roles in different biological pathways.

Dhindsa says that these models have exceptionally high predictive value.

“Top-ranked genes were up to two-fold or six-fold, depending on the mode of inheritance, more enriched for high-confidence neurodevelopmental disorder risk genes compared to genic intolerance metrics alone,” he said in the release. “Additionally, some top-ranking genes were 45 to 500 times more likely to be supported by the literature than lower-ranking genes.”

That means that the models may actually validate genes that haven’t yet been proven to be involved in neurodevelopmental conditions. Gene discovery done with the help of AI could possibly become the new normal for families seeking answers beyond umbrella terms like “autism spectrum disorder.”

“We hope that our models will accelerate gene discovery and patient diagnoses, and future studies will assess this possibility,” Dhindsa added.

Texas robotics co. begins new search for missing Malaysia Airlines flight 370

International News

Malaysia’s government has given final approval for a Texas-based marine robotics company to renew the search for Malaysia Airlines Flight 370, which is believed to have crashed in the southern Indian Ocean more than a decade ago.

Cabinet ministers agreed to terms and conditions for a “no-find, no-fee” contract with Texas-based Ocean Infinity to resume the seabed search operation at a new 5,800-square-mile site in the ocean, Transport Minister Anthony Loke said in a statement Wednesday. Ocean Infinity will be paid $70 million only if wreckage is discovered.

The Boeing 777 plane vanished from radar shortly after taking off on March 8, 2014, carrying 239 people, mostly Chinese nationals, on a flight from Malaysia’s capital, Kuala Lumpur, to Beijing. Satellite data showed the plane turned from its flight path and headed south to the far-southern Indian Ocean, where it is believed to have crashed.

An expensive multinational search failed to turn up any clues to its location, although debris washed ashore on the east African coast and Indian Ocean islands. A private search in 2018 by Ocean Infinity also found nothing.

The final approval for a new search came three months after Malaysia gave the nod in principle to plans for a fresh search.

Ocean Infinity CEO Oliver Punkett earlier this year reportedly said the company had improved its technology since 2018. He has said the firm is working with many experts to analyze data and had narrowed the search area to the most likely site.

Loke said his ministry will ink a contract with Ocean Infinity soon but didn’t provide details on the terms. The firm has reportedly sent a search vessel to the site and indicated that January-April is the best period for the search.

“The government is committed to continuing the search operation and providing closure for the families of the passengers of flight MH370,” he said in a statement.

Harris County booms with 3rd biggest population in U.S.

Boomtown

Newly released U.S. Census Bureau data has revealed Harris County became the third most populous county nationwide in 2024, and it had the highest year-over-year growth rate from 2023.

The new population report, published this month, estimated year-over-year population data from 2023 to 2024 across all 3,144 U.S. counties, and 387 metro areas.

Harris County's numeric growth rate outpaced all other U.S. counties from July 1, 2023 to July 1, 2024, the report found. The Census Bureau estimated Harris County's population grew by 105,852 people year-over-year, bringing the total population to 5,009,302 residents. That's around a 2.16 percent growth rate.

Los Angeles County, California (No. 1) and Illinois' Cook County (No. 2) are the only two U.S. counties that have larger populations than Harris County. Los Angeles County now boasts a population of nearly 9.76 million, while Cook County's has increased to more than 5.18 million people.

The top 10 most populous counties in the U.S. are:

  • No. 1 – Los Angles County, California
  • No. 2 – Cook County, Illinois
  • No. 3 – Harris County, Texas
  • No. 4 – Maricopa County, Arizona
  • No. 5 – San Diego County, California
  • No. 6 – Orange County, California
  • No. 7 – Miami-Dade County, Florida
  • No. 8 – Dallas County, Texas
  • No. 9 – Kings County, New York
  • No. 10 – Riverside County, California

Montgomery County also ranked among the top 10 U.S. counties with the highest numeric growth, ranking 9th nationally after gaining 34,268 residents from 2023 to 2024. Montgomery County's population has now grown to 749,613 people.

In the report's national comparison of counties with the largest population growth by percentage, Montgomery County ranked No. 7 with a year-over-year growth rate of 4.8 percent.

Most populated U.S. metro areas

The U.S. Census Bureau additionally found Houston-Pasadena-The Woodlands nearly led the nation as the second-fastest growing metro area in 2024.

From July 2023 to July 2024, the Houston metro added 198,171 residents to bring the total population to 7,796,182.

New York-Newark-Jersey City was the only metro area to outpace Houston's growth during the one-year period. The New York-New Jersey metro added 213,403 new residents, which brought the total population to over 19.94 million last year.

Kristie Wilder, a Census Bureau Population Division demographer, said in the report that the nation's population growth in its major metros was largely impacted by international migration rather than changes in birth rates.

"While births continue to contribute to overall growth, rising net international migration is offsetting the ongoing net domestic outmigration we see in many of these areas," Wilder said.

Dallas-Fort Worth-Arlington was right behind Houston as the third-fastest growing U.S. metro in 2024. The Metroplex gained 177,922 residents last year, and now has a total population of more than 8.34 million.

The top 10 U.S. metros with the highest numeric growth from 2023 to 2024 are:

  • No. 1 – New York-Newark-Jersey City, New York-New Jersey
  • No. 2 – Houston-Pasadena-The Woodlands, Texas
  • No. 3 – Dallas-Fort Worth-Arlington, Texas
  • No. 4 – Miami-Fort Lauderdale-West Palm Beach, Florida
  • No. 5 – Washington-Arlington-Alexandria, D.C.-Virginia-Maryland-West Virginia
  • No. 6 – Phoenix-Mesa-Chandler, Arizona
  • No. 7 – Orlando-Kissimmee-Sanford, Florida
  • No. 8 – Atlanta-Sandy Springs-Roswell, Georgia
  • No. 9 – Chicago-Naperville-Elgin, Illinois-Indiana
  • No. 10 – Seattle-Tacoma-Bellevue, Washington
