Rajan Shah, an MIT-trained chemical engineer, brought his patented manufacturing process 20 years in the making and from an ocean away to Houston with one goal in mind: to take what he calls the body's "master antioxidant" to market.

Known as Continual G, Shah's product packs the supplement known as Glyteine into a powder form that when mixed with water can be consumed as a citrus-flavored beverage. Glyteine is known to increase cellular glutathione levels in the body, which can boost immunity, support sports activity and recovery, and address a variety of oxidative stressors that impact the body and brain as humans age.

Shah and a team of four at his INID Research Lab in Cypress are the only company in the world producing the dipeptide in this accessible format.

"The fact that the only way to increase cellular glutathione is with Glyteine has been known for almost 40 years," Shah says. "The problem is how to make it in a way which becomes cost effective so that it can be sold and people can afford to buy it."

It was this problem that Shah and a team at the University of New South Wales in Australia spent about 13 years tackling, as the creation the Glyteine — which requires the rare catalyzation of enzymes — would leave researchers with expensive byproduct that would result in high costs for little product. But in 2005, the university was awarded a patent for the manufacturing process the group developed that essentially eliminated waste. Instead, they were able to recycle the by product to create even more of the powerful protein.

"Only when we could solve these problems did it become affordable. Then you are using your raw materials to produce your product and nothing else. We were able to recycle," Shah explains. "That is what took the time and that is what made it affordable cost wise."

Next the group spent years scaling the production of the compound and learning how to best deploy it to a customer base. Initially, the group hoped to simply sell the protein to large supplement companies, such as GNC. But when they were met with reservations due to the product's newness, they pivoted.

Houston's large pool of chemical manufacturing workers and easy access to water (a key ingredient in Continual G's production) attracted the Aussie-based scientist. And in 2017, Shah took the practices from down under to the Bayou City just days before Hurricane Harvey hit.

Today the group is producing about a quarter of a million packets of Continual G each month with the help of an outsourced, Texas-based manufacturer who assists the group of engineers in transposing the compound into a drinkable powder. They operate out of a state-of-the-art, 14,000-square-foot manufacturing facility and hope to scale up again.

"Everyone involved with this endeavor has a heartfelt commitment," Shah adds in a statement. "Glyteine has profound implications for human health. That alone has made it well worth the effort to overcome every challenge we have faced and continue to face."

Houston team uses CPRIT funding to develop nanodrug for cancer immunotherapy

cancer research

With a relative five-year survival rate of 50 percent, pancreatic cancer is a diagnosis nobody wants. At 60 percent, the prognosis for lung cancer isn’t much rosier. That’s because both cancers contain regulatory B cells (Bregs), which block the body’s natural immunity, making it harder to fight the enemies within.

Newly popular immunotherapies in a category known as STING agonists may stimulate natural cancer defenses. However, they can also increase Bregs while simultaneously causing significant side effects. But Wei Gao, assistant professor of pharmacology at the University of Houston College of Pharmacy, may have a solution to that conundrum.

Gao and her team have developed Nano-273, a dual-function drug, packaged in an albumin-based particle, that boosts the immune system to help it better fight pancreatic and lung cancers. Gao’s lab recently received a $900,000 grant from the Cancer Prevention and Research Institute of Texas (CPRIT) to aid in fueling her research into the nanodrug.

“Nano-273 both activates STING and blocks PI3Kγ—a pathway that drives Breg expansion, while albumin nanoparticles help deliver the drug directly to immune cells, reducing unwanted side effects,” Gao said in a press release. “This approach reduces harmful Bregs while boosting immune cells that attack cancer, leading to stronger and more targeted anti-tumor responses.”

In studies using models of both pancreatic and lung cancers, Nano-273 has shown great promise with low toxicity. Its best results thus far have involved using the drug in combination with immunotherapy or chemotherapy.

With the CPRIT funds, Gao and her team will be able to charge closer to clinical use with a series of important steps. Those include continuing to test Nano-273 alongside other drugs, including immune checkpoint inhibitors. Safety studies will follow, but with future patients in mind, Gao will also work toward improving her drug’s production, making sure that it’s safe and high-quality every time, so that it is eventually ready for trials.

Gao added: “If successful, this project could lead to a new type of immunotherapy that offers lasting tumor control and improved survival for patients with pancreatic and lung cancers, two diseases that urgently need better treatments."

Houston booms as No. 2 U.S. metro for new home construction

Construction Boom

Driven by population growth, more residential rooftops are popping up across Houston and the rest of Texas than anywhere else in America.

Using data from the U.S. Census Bureau and Zillow, Construction Coverage found 65,747 new residential units were authorized in greater Houston in 2024. That figure landed Houston in second place among major metro areas for the total number of housing permits, including those for single-family homes, apartments, and condos.

Just ahead of Houston was the Dallas-Fort Worth Metroplex, which took first place with 71,788 residential permits approved in 2024. In third place was the country’s largest metro, New York City (57,929 permits).Elsewhere in Texas, the Austin metro ranked sixth (32,294 permits), and the San Antonio metro ranked 20th (14,857 permits).

Construction Coverage also sorted major metro areas based on the number of new housing units authorized per 1,000 existing homes in 2024. Raleigh, North Carolina, held the No. 1 spot (28.8 permits per 1,000 existing homes), followed by Austin at No. 2 (28.6), DFW at No. 3 (22.2), Houston at No. 4 (21.6), and San Antonio at No. 13 (13.6).

A Newsweek analysis of Census Bureau data shows building permits for 225,756 new residential units were approved in 2024 in Texas — a trend fueled largely by activity in DFW, Houston, Austin, and San Antonio. That put Texas atop the list of states building the most residential units for the year.

Through the first eight months of last year, 145,901 permits for new residential units were approved in Texas, according to Census Bureau data. That’s nearly 80,000 permits shy of the 2024 total.

Among the states, Construction Coverage ranks Texas sixth for the number of residential building permits approved in 2024 per 1,000 existing homes (17.9).

Extra housing is being built in Texas to meet demand spurred by population growth. From April 2020 to July 2024, the state’s population increased 7.3 percent, the Census Bureau says.

While builders are busy constructing new housing in Texas, they’re not necessarily profiting a lot from homebuilding activity.

“Market conditions remain challenging, with two-thirds of builders reporting they are offering incentives to move buyers off the fence,” North Carolina homebuilder Buddy Hughes, chairman of the National Association of Home Builders, said in a December news release. “Meanwhile, builders are contending with rising material and labor prices, as tariffs are having serious repercussions on construction costs.”
