“We are at this inflection point where marketing is changing,” May says in a press release. “We know that the next generation can clearly see that and I think a lot of marketing agencies are starting to catch on. We need to be prioritizing the next generation’s opinion because they are driving who is interested in what they buy. This upcoming generation does not want to be sold to and they don’t like inorganic, inauthentic advertisements. That’s why user generated content is so big, it feels authentic.” Continue reading.

Abbott highlights Texas AI boom, with Houston projects on the horizon

AI investments are booming in Texas, Gov. Greg Abbott says. And Houston is poised to benefit from this surge.

At a recent Texas Economic Development Corp. gathering in the Dallas-Fort Worth area, Abbott said AI projects on the horizon in the Lone Star State would be bigger than the $500 billion multistate Project Stargate, according to the Dallas Business Journal. So far, Stargate includes three AI data centers in Texas.

Stargate, a new partnership among OpenAI, Oracle, Softbank, and the federal government, is building AI infrastructure around the country. The project’s first data center is in Abilene, and the center’s second phase is underway. Once the second phase is finished, the 875-acre site will host eight buildings totaling about 4 million square feet with a power capacity of 1.2 gigawatts. An additional 600 megawatts of capacity might be added later.

On Sept. 23, Stargate announced the development of another five AI data centers in the U.S., including a new facility in Shackelford County, Texas, near Abilene. That facility is likely a roughly $25 billion, 1.4-gigawatt AI data center that Vantage Data Centers is building on a 1,200-acre site in Shackelford County.

Another will be in Milam County, between Waco and Austin. In conjunction with Stargate, OpenAI plans to occupy the more than $3 billion center, which will be situated on a nearly 600-acre site, the Austin Business Journal reported. OpenAI has teamed up with Softbank-backed SB Energy Global to build the facility.

Abbott said several unannounced AI projects in Texas — namely, data centers — will be larger than Stargate.

“Bottom line is ... when you look at diversification, the hottest thing going on right now is artificial intelligence,” Abbott said.

The Houston area almost certainly stands to attract some of the projects teased by the governor.

In Houston, Taiwanese tech manufacturer Foxconn already is investing $450 million to make AI servers at the 100-acre Fairbanks Logistics Park, which Foxconn recently purchased for a reported $142 million. The park features four industrial buildings totaling one million square feet. It appears Foxconn will manufacture the servers for Apple and Nvidia, both of which have announced they’ll open server factories in Houston.

The Foxconn, Apple, and Nvidia initiatives are high-profile examples of Houston’s ascent in the AI economy. A report released in July by the Brookings Institution identified Houston as one of the country’s 28 “star” hubs for AI.

The Greater Houston Partnership says the Houston area is undergoing an "AI-driven data revolution."

“As Houston rapidly evolves into a hub for AI, cloud computing, and data infrastructure, the city is experiencing a surge in data center investments driven by its unique position at the intersection of energy, technology, and innovation,” the partnership says.

A team of engineers and pediatric surgeons led by Rice University’s Rice360 Institute for Global Health Technologies has developed a cost-effective treatment for infants born with gastroschisis, a congenital condition in which intestines and other organs are developed outside of the body.

The condition can be life-threatening in economically disadvantaged regions without access to equipment.

The Rice-developed device, known as SimpleSilo, is “simple, low-cost and locally manufacturable,” according to the university. It consists of a saline bag, oxygen tubing and a commercially available heat sealer, while mimicking the function of commercial silo bags, which are used in high-income countries to protect exposed organs and gently return them into the abdominal cavity gradually.
