Great inventions reveal their value within due course, but there are those creations that tell their worth almost immediately, with a first look, image, or mere mention.

The Cold Cork, a malleable pouring device that instantly chills wine and spirits, falls into that category.

It seems like such a simple idea, but that’s the thing about inventions, isn’t it? Anyone can come up with an idea, but it’s the ones that can execute that idea that make it to the finish line and etch their names in the annals of creative glory.

“I had come home from the grocery store, right at the onset of COVID, and I wanted to have a glass of wine that I bought, but it was already room temperature, and I didn't want to put ice in it,” says wine-lover and former healthcare worker Michelle Kurkiewicz. “So, we started doing some research and came up with the idea for Cold Cork.”

Timing is everything, and because the nationwide pause caused by the COVID-19 pandemic offered Michelle, 33, and her husband Tyler, 30, plenty of free time, the dutiful duo was able to flesh out their labor of love.

As it turns out, Tyler, a mechanical engineer by trade, had recently purchased a 3D printer back in January 2020, so he was able to use it to build hundreds of prototypes in-house to eventually arrive at a final design, which is based on the couple’s wedding champagne flutes.

So how does the Cold Cork work? Picture this: the wine-lover takes the Cold Cork out of the freezer (after a recommended 24 hours to thoroughly freeze), places it on top of the open bottle of wine and begins to pour.

As the liquid funnels through the stainless-steel coil, which is surrounded by a proprietary, food-grade cooling medium, the wine or spirits is chilled by 20 degrees in just 20 seconds.

To achieve the best results for red wine, pour the entire bottle through the Cold Cork into a decanter and enjoy.

And the best part? Not one part of the Cold Cork’s signature process alters the taste or composition of the drink in any way.

“At first, we thought about whether the product should be inside the bottle or outside the bottle,” remembers Tyler. “But we quickly realized that there’s simply not enough room to do that amount of chilling inside a bottle. And we didn't want to have to pour any wine out. But we needed to make space to put some sort of chiller in the bottle. And so, we immediately started looking outside the bottle, and just with all the other wine gadgets, being bottle-topped and plugging in with a rubber stopper, that's immediately the direction we sort of drifted to.”

According to Tyler, the first couple of prototypes were made of a 3D filament. Initially, the idea was to focus on creating a cooling gel to compliment the coil, but that got a bit messy and, of course, there were too many wine taste-testing sessions to count.

“We definitely went through a lot of bottles of wine,” says Michelle. “But one of the first people that used our product was a sommelier and she loved it. We also gave one of our first production-level prototypes to a friend who is a manager at a restaurant. She used it on several occasions and said it was perfect for what she needed and seeing our product be used at a place that we frequented was extremely validating.”

Armed with the validation they needed to go to production, the wine-loving public could now have the product they needed to keep from having to throw all their wine in the refrigerator.

“The Cold Cork is really good for the people that maybe don't have those multi-zone fridges,” says Michelle. “We found a good niche with entry-level wine drinkers that don't have a wine fridge, but they want to drink their white wines still without being over-drank with ice cubes.

“That's really who we've been going after, and who we've seen has found a lot of value in the product. It's really the people that maybe aren't so prepared or maybe looking just for some more accessible solutions, whether it's because of the space in their apartment or financially, you know, it might be cheaper than a wine fridge. That's why we came up with the Cold Cork ourselves, because that was us, and so we kind of made a product that worked for us and found that there are a lot of people like that.”

The Cold Cork is available now and can be purchased directly from the company’s website for $64.95. In the future, more cork sizes and different colors will be offered, and more brick-and-mortar stores will carry the product. The couple pitched the idea and received investment from Trend Ventures at the 2022 Build Up Buttercup, an initiative that featured small business pitches for a select group of investors.

“We’ve gotten a lot of feedback directly from customers saying they use it a lot more than they thought,” says Michelle. “But then there are those people that are skeptical about how it works. That’s why I love to demo the Cold Cork in person.”

For a couple that met at a bar one night in downtown Houston, the Cold Cork is almost a poetic destination as a business endeavor and one that they both really relish.

“We both have our strengths, and we give each other a lot of support,” says Michelle.

“I’m very mechanically inclined, so I develop and invent, and Michelle is great with the marketing aspect and working with people to purchase the product,” adds Tyler. “In addition to the Cold Cork, we do have a couple of early projects that we are working on. I think there is a lot of opportunity with our technology to take what we have learned and fit that into different product lineups moving forward.”

Texas cybersecurity co. expands unique train-to-hire model to Houston

job search

It’s increasingly more difficult to ensure the confidentiality, integrity, and availability of proprietary data and information in the ever-changing, ever-evolving digital world.

Cyberattacks, including malware, phishing, and ransomware, are becoming increasingly common and sophisticated, posing a consistent threat to a company’s sustainability and bottom line.

To combat that trend, Nukudo, a San Antonio-based cybersecurity workforce development company, is expanding its initiative to bridge the global cybersecurity talent gap through immersive training and job placement to Houston.

“We saw that there was a need in the market because there's a shortage of skilled manpower within the cybersecurity industry and other digital domains,” says Dean Gefen, CEO of NukuDo. “So, our initial goal was to take a large pool of people and then make them to be fully operational in cybersecurity in the shortest amount of time.”

The company refers to the plan as the “training-to-employment model,” which focuses on providing structured training to select individuals who then acquire the skills and knowledge necessary to secure and maintain fruitful careers.

The company identifies potential associates through its proprietary aptitude test, which recognizes individuals who possess the innate technical acumen and potential for success in various cybersecurity roles, regardless of their level of education.

“We take in people from all walks of life, meaning the program is purely based on the associate’s potential,” Gefen says. “We have people who were previously aircraft engineers, teachers, graphic designers, lawyers, insurance agents and so forth.”

Once selected, associates are trained by cybersecurity experts while gaining hands-on experience through scenario-based learning, enabling them to be deployed immediately as fully operational cybersecurity professionals.

The program training lasts just six months—all paid—followed by three years of guaranteed employment with NukuDo.

While in training, associates are paid $ 4,000 per month; then, they’re compensated by nearly double that amount over the next three years, ultimately pushing their salaries to well into the six figures after completing the entire commitment.

In addition to fostering a diverse talent pipeline in the cybersecurity field, NukuDo is creating a comprehensive solution to address the growing shortage of technical talent in the global workforce.

And arming people with new marketable skills has a litany of benefits, both professional and personal, Gefen says.

“Sometimes, we have associates who go on to make five times their previous salary,” says Gefen. “Add to that fact that we had someone that had a very difficult life beforehand and we were able to put him on a different path. That really hits home for us that we are making a difference.

Nulkudo currently has partnerships with companies such as Accenture Singapore and Singapore Airlines. Gefen says he and his team plans to have a new class of associates begin training every month by next year and take the model to the Texas Triangle (Houston, Austin and Dallas)—then possibly nationwide.

“The great thing about our program is that we train people above the level of possible threat of replacement by artificial intelligence,” Gefen says. “But what we are also doing, and this is due to requirements that we have received from clients that are already hiring our cyber professionals, is that we are now starting to deliver AI engineers and data scientists in other domains.”

“That means that we have added more programs to our cybersecurity program. So, we're also training people in data science and machine learning,” he continues.

All interested candidates for the program should be aware that a college degree is not required. NukuDo is genuinely interested in talented individuals, regardless of their background.

“The minimum that we are asking for is high school graduates,” Gefen says. “They don't need to have a college degree; they just need to have aptitude. And, of course, they need to be hungry to make this change.”

2 Houston universities declared among world’s best in 2026 rankings

Declaring the Best

Two Houston universities are in a class of their own, earning top spots on a new global ranking of the world's best universities.

Rice University and University of Houston are among the top 1,200 schools included in the QS World University Rankings 2026. Ten more schools across Texas make the list.

QS (Quacquarelli Symonds), a London-based provider of higher education data and analytics, compiles the prestigious list each year; the 2026 edition includes more than 1,500 universities from around the world. Factors used to rank the schools include academic reputation; employer reputation; faculty-student ratio; faculty research; and international research, students, and faculty.

In Texas, University of Texas at Austin lands at No. 1 in the state, No. 20 in the U.S., and No. 68 globally.

Houston's Rice University is close behind as Texas' No. 2 school. It ranks 29th in the U.S. and No. 119 in the world. Unlike UT, which fell two spots globally this year (from No. 66 to 68), Rice climbed up the charts, moving from 141st last year to No. 119.

University of Houston impresses as Texas' 4th highest-ranked school. It lands at No. 80 in the U.S. and No. 556 globally, also climbing about 100 spots up the chart.

Rice and UH are on a roll in regional, national, and international rankings this year.

Rice earned top-15 national rankings by both Niche.com and Forbes last fall. Rice claimed No. 1 and UH ranked No. 8 in Texas in U.S. News & World Report's 2025 rankings. Rice also topped WalletHub's 2025 list of the best colleges and universities in Texas for 2025.

More recently, in April, both UH and Rice made U.S. News' 2025 list of top grad schools.

In all, 192 U.S. universities made the 2026 QS World University Rankings — the most of any country. Topping the global list is the Massachusetts Institute of Technology (MIT).

“The results show that while U.S. higher education remains the global leader, its dominance is increasingly challenged by fast-rising emerging systems,” says the QS World University Rankings report. “A decade ago, 32 American universities [were] featured in the world’s top 100; today, that number has dropped to 26, and only 11 of these institutions have improved their position this year."

The 12 Texas universities that appear in the QS World University Rankings 2026 list are:

  • University of Texas at Austin, No. 20 in the U.S. and No. 68 in the world (down from No. 66 last year).
  • Rice University, No. 29 in the U.S. and No. 119 in the world (up from No. 141 last year).
  • Texas A&M University, No. 32 in the U.S. and No. 144 in the world (up from No. 154 last year).
  • University of Houston, No. 80 in the U.S. and No. 556 in the world (up from 651-660 last year).
  • University of Texas at Dallas, No. 85 in the U.S. and No. 597 in the world (down from 596 last year).
  • Texas Tech University, No. 104 in the U.S. and No. 731-740 in the world (unchanged from last year).
  • University of North Texas, No. 123 in the U.S. and No. 901-950 in the world (up from 1,001-1,200 last year)
  • Baylor University, tied for No. 136 in the U.S. and at No. 1,001-1,200 in the world (unchanged from last year).
  • Southern Methodist University, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas Arlington, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas at San Antonio, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas at El Paso, No. 172 in the U.S. and at 1,201-1,400 in the world (down from 1,001-1,200 last year).

Houston students develop new device to prepare astronauts for outer space

space race

Rice University students from the George R. Brown School of Engineering and Computing designed a space exercise harness that is comfortable, responsive, and adaptable and has the potential to assist with complex and demanding spacewalks.

A group of students—Emily Yao, Nikhil Ashri, Jose Noriega, Ben Bridges and graduate student Jack Kalicak—mentored by assistant professor of mechanical engineering Vanessa Sanchez, modernized harnesses that astronauts use to perform rigorous exercises. The harnesses are particularly important in preparing astronauts for a reduced-gravity space environment, where human muscles and bones atrophy faster than they do on Earth. However, traditional versions of the harnesses had many limitations that included chafing and bruising.

The new harnesses include sensors for astronauts to customize their workouts by using real-time data and feedback. An additional two sensors measure astronauts’ comfort and exercise performance based on temperature and humidity changes during exercise and load distribution at common pressure points.

“Our student-led team addressed this issue by adding pneumatic padding that offers a customized fit, distributes pressure over a large surface area to reduce discomfort or injuries and also seamlessly adapts to load shifts — all of which together improved astronauts’ performance,” Sanchez said in a news release. “It was very fulfilling to watch these young engineers work together to find innovative and tangible solutions to real-world problems … This innovative adjustable exercise harness transforms how astronauts exercise in space and will significantly improve their health and safety during spaceflights.”

The project was developed in response to a challenge posted by the HumanWorks Lab and Life Science Labs at NASA and NASA Johnson Space Center for the 2025 Technology Collaboration Center’s (TCC) Wearables Workshop and University Challenge, where teams worked to solve problems for industry leaders.

Rice’s adaptive harness won the Best Challenge Response Award. It was funded by the National Science Foundation and Rice’s Office of Undergraduate Research and Inquiry.

“This challenge gave us the freedom to innovate and explore possibilities beyond the current harness technology,” Yao added in the release. “I’m especially proud of how our team worked together to build a working prototype that not only has real-world impact but also provides a foundation that NASA and space companies can build and iterate upon.”
