Han Xiao, associate professor of chemistry at Rice University

The funds were awarded to Han Xiao, a chemist at Rice University.

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 advance his work on noncanonical amino acids.

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

Houston chemist lands $2M NIH grant for cancer treatment research

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.

Tesla recalling more than 375,000 vehicles due to power steering issue

Tesla Talk

Tesla is recalling more than 375,000 vehicles due to a power steering issue.

The recall is for certain 2023 Model 3 and Model Y vehicles operating software prior to 2023.38.4, according to the National Highway Traffic Safety Administration.

The printed circuit board for the electronic power steering assist may become overstressed, causing a loss of power steering assist when the vehicle reaches a stop and then accelerates again, the agency said.

The loss of power could required more effort to control the car by drivers, particularly at low speeds, increasing the risk of a crash.

Tesla isn't aware of any crashes, injuries, or deaths related to the condition.

The electric vehicle maker headed by Elon Musk has released a free software update to address the issue.

Letters are expected to be sent to vehicle owners on March 25. Owners may contact Tesla customer service at 1-877-798-3752 or the NHTSA at 1-888-327-4236.

Houston space tech companies land $25 million from Texas commission

Out Of This World

Two Houston aerospace companies have collectively received $25 million in grants from the Texas Space Commission.

Starlab Space picked up a $15 million grant, and Intuitive Machines gained a $10 million grant, according to a Space Commission news release.

Starlab Space says the money will help it develop the Systems Integration Lab in Webster, which will feature two components — the main lab and a software verification facility. The integration lab will aid creation of Starlab’s commercial space station.

“To ensure the success of our future space missions, we are starting with state-of-the-art testing facilities that will include the closest approximation to the flight environment as possible and allow us to verify requirements and validate the design of the Starlab space station,” Starlab CEO Tim Kopra said in a news release.

Starlab’s grant comes on top of a $217.5 million award from NASA to help eventually transition activity from the soon-to-be-retired International Space Station to new commercial destinations.

Intuitive Machines is a space exploration, infrastructure and services company. Among its projects are a lunar lander designed to land on the moon and a lunar rover designed for astronauts to travel on the moon’s surface.

The grants come from the Space Commission’s Space Exploration and Aeronautics Research Fund, which recently awarded $47.7 million to Texas companies.

Other recipients were:

  • Cedar Park-based Firefly Aerospace, which received $8.2 million
  • Brownsville-based Space Exploration Technologies (SpaceX), which received $7.5 million
  • Van Horn-based Blue Origin, which received $7 million

Gwen Griffin, chair of the commission, says the grants “will support Texas companies as we grow commercial, military, and civil aerospace activity across the state.”

State lawmakers established the commission in 2023, along with the Texas Aerospace Research & Space Economy Consortium, to bolster the state’s space industry.
