Dozens of Houston-area businesses appear in this year’s Inc. 5000 ranking of the 5,000 fastest-growing private companies in the U.S., with a security software provider capturing the region’s No. 1 spot on the list.

Landing at No. 29 nationally and No. 1 in the software category, the top-ranked Houston-area private company is Houston-based Action1. The company recorded median revenue growth of 7,188 percent from 2021 to 2024, according to the Inc. 5000.

It’s the first appearance on the Inc. 5000 list for Action1, founded in 2018.

Action1 produces patch management software. A patch, or fix, quickly repairs software to resolve functionality problems, improve security or add features, according to TechTarget.

“Modern organizations understand that proactive patch management is essential to staying ahead of today’s rapidly evolving threat landscape,” Mike Walters, co-founder and president of Action1, said in a news release. “Our continued hypergrowth reflects the increased demand for enterprise cybersecurity innovation. You can’t be just powerful and secure — you must also be simple to deploy and scale and cost-effective.”

Houston native picked for 2025 class of NASA astronaut candidates

space crew

NASA has selected 10 new astronaut candidates, including one whose hometown is Houston, for its 2025 training class. The candidates will undergo nearly two years of training before they can assume flight assignments.

The 10 future astronauts were introduced during a recent ceremony at NASA’s Johnson Space Center, whose facilities include an astronaut training center. NASA received more than 8,000 applications for the 10 slots.

“Representing America’s best and brightest, this astronaut candidate class will usher in the Golden Age of innovation and exploration as we push toward the moon and Mars,” said Vanessa Wyche, director of NASA Johnson.

NASA’s 24th astronaut class reported for duty in mid-September at Johnson Space Center. Their training will prepare them for missions to the International Space Station and the moon, among other activities. Graduates will become members of NASA’s astronaut corps.

Among the recently selected candidates is Anna Menon, who was born in Houston and considers it her hometown. She’s married to NASA astronaut Dr. Anil Menon, a flight surgeon who completed his training in 2022.

Most recently, Anna Menon was a senior engineer at Elon Musk’s SpaceX, where she spent seven years managing crew operations for the Dragon and Starship spacecraft. Previously, Menon worked at NASA’s Mission Control Center in Houston, where she supported medical software and hardware aboard the International Space Station.

In 2024, Menon flew into space as a mission specialist and medical officer aboard SpaceX’s Polaris Dawn private spacecraft. A highlight of the low-orbit trip was the first commercial spacewalk.

Texas native Rebecca Lawler, a native of the Dallas-Fort Worth suburb of Little Elm, is one of Menon’s nine classmates.

Lawler, a former lieutenant commander in the Navy, was a Navy P-3 pilot and experimental test pilot who logged over 2,800 flight hours aboard more than 45 aircraft. At the time she was chosen to be an astronaut candidate, Lawler was a test pilot for United Airlines.

The eight other astronaut candidates in the 2025 class are:

Ben Bailey, who was born and raised in Charlottesville, Virginia
Lauren Edgar, whose hometown is Sammamish, Washington
Adam Fuhrmann, who’s from Leesburg, Virginia
Cameron Jones, a native of Savanna, Illinois
Yuri Kubo, a native of Columbus, Indiana
Imelda Muller, whose hometown is Copake Falls, New York
Erin Overcash, who’s from Goshen, Kentucky
Katherine Spies, a native of San Diego

Two Rice University undergraduate engineering students have developed a non-invasive vibrotactile glove that aims to alleviate the symptoms of Parkinson’s disease through therapeutic vibrations. Emmie Casey and Tomi Kuye developed the project with support from the Oshman Engineering Design Kitchen (OEDK).

Based on research from the Peter Tass Lab at Stanford University, the Rice team set out to replicate the breakthrough technology at a lower cost. They are working to develop a commercial version of the glove priced at $250 and are taking preorders now, with hopes to deliver 500 gloves this fall. Read more.

A team of researchers at the University of Houston led by professor Mim Rahimi has made two breakthroughs in addressing climate change and potentially reducing the cost of capturing harmful emissions from power plants.

The first introduces a membraneless electrochemical process that cuts energy requirements and costs for amine-based carbon dioxide capture during the acid gas sweetening process. The second demonstrates a vanadium redox flow system capable of both capturing carbon and storing renewable energy.

“From membraneless systems to scalable flow systems, we’re charting pathways to decarbonize hard-to-abate sectors and support the transition to a low-carbon economy,” Rahimi said. Read more.
