Academics are learning quickly that investigations based on data from online research agencies have their drawbacks. Thousands of such studies are released every year – and if the data is compromised, so too are the studies themselves.

So it’s natural for researchers, and the managers who rely on their findings, to be concerned about potential problems with the samples they’re studying. Among them: participants who aren’t in the lab and researchers who can’t see who is taking their survey, what they are doing while answering questions or even if they are who they claim to be online. In the wake of a 2018 media piece about Amazon’s Mechanical Turks Service, “Bots on Amazon’s MTurk Are Ruining Psychology Studies,” one psychology professor even mused, “I wonder if this is the end of MTurk research?” (It wasn’t).

To tackle this problem, Rice Business professor Mikki Hebl joined colleagues Carlos Moreno and Christy Nittrouer of Rice University along with several other colleagues to highlight the value of other research methods. Four alternatives – field experiments, archival data, observations and big data – represent smart alternatives to overreliance on online surveys. These methods also have the advantage of challenging academics to venture outside of their laboratories and examine real people and real data in the real world.

Field experiments have been around for decades. But their value is hard to overestimate. Unlike online studies, field experiments enhance the role of context, especially in settings that are largely uncontrolled. It’s hard to fake a field experiment in order to create positive results since each one costs a considerable time and money.

And field experiments can yield real-life results with remarkable implications for society at large. Consider one experiment among 56 middle schools in New Jersey, which found that spreading anti-conflict norms was hugely successful in reducing the need for disciplinary action. Such studies have an impact well beyond what could be achieved with a simple online survey.

The best way to get started with a good field experiment, Hebl and her colleagues wrote, is for researchers to think about natural field settings to which they have access, either personally or by leveraging their networks. Then, researchers should think about starting with the variables critical for any given setting and which they would most like to manipulate to observe the outcome. When choosing variables, it’s helpful to start by thinking about what variable might have conditions leading to the greatest degree of behavior change if introduced into the setting.

Archival data is another excellent way to work around the limitations of online surveys, the researchers argue. These data get around some of the critical drawbacks of field research, including problems around how findings apply in a more general way. Archival data, especially in the form of state or national level data sets, provide information and insight into a large, diverse set of samples that are more representative of the general population than online studies.

Archival data can also help answer questions that are either longitudinal or multilevel in nature, which can be particularly tricky or even impossible to capture with data collected by any single research team. As people spend increasing amounts of time on social media, the internet also serves as a source of newer forms of archival data that can lend unique insights into individuals’ thoughts, attitudes, and behaviors over time.

With every passing year, technology becomes increasingly robust and adept at collecting massive amounts of data on an endless variety of human behavior. For the scientists who research social and personality psychology, the term “big data” refers not only to very large sets of data but also to the tools and techniques that are used to analyze it. The three defining properties of Big Data in this context include the speed of data processing and collection, the vast amount of data being analyzed and the sheer variety of data available.

By using big data, social scientists can generate research based on various conditions, as well as collect data in natural settings. Big data also offers the opportunity to consolidate information from huge and highly diverse stores of data. This technology has many applications, including psychological assessments and improving security in airports and other transportation hubs. In future research, Hebl and her team noted, researchers will likely leverage big data and its applications to detect our unconscious emotions.

Big data, archival information and field studies can all be used in conjunction with each other to maximize the fidelity of research. But researchers shouldn’t forget even more old-fashioned techniques, including the oldest: keen observation. With observation, there are often very few, if any, manipulations and the goal is simply to systematically record the way people behave.

Researchers – and the managers who make decisions based on their findings – should consider the advantages of old-style, often underused methodologies, Hebl and her colleagues argue. Moving beyond the college laboratory and digital data survey-collection platforms and into the real world offers some unparalleled advantages to science. For the managers whose stock prices may hinge on this science, it’s worth knowing – and understanding – how your all-important data was gathered.

Venus Aerospace closes $91M funding round to scale hypersonic engine

flight funding

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were named to the World Economic Forum's Technology Pioneers community earlier this summer. Read more here.

Intuitive Machines lands $148M as part of NASA Moon Base funding

to the moon

Houston-based Intuitive Machines has been awarded $148.3 million to deliver its Nova-C lander to the moon by 2028. The funding is part of $600 million that NASA recently awarded to three companies as part of the agency’s Moon Base Program.

The contracts aim to support sustained human presence and commercial operations on the Moon. Austin-based Firefly Aerospace was awarded $144.2 million by NASA for one mission and Pittsburgh-based Astrobotic netted $297.9 million for two lunar landings. Intuitive Machine's award is the company's sixth task order under NASA's Commercial Lunar Payload Services (CLPS) program.

“We’re building a proving ground for Moon Base operations,” Ryan Stephan, NASA’s Moon Base acting director of cargo landers, said in a news release. “Accelerating our Moon mission ordering cadence and launch opportunities enable us to move quickly to learn, iterate, and improve.”

Under the latest task order, Intuitie Machines will deliver three scientific and operational payloads to the moon, which include a:

  • Linear Energy Transfer Spectrometer (LETS) radiation monitor to gather critical environmental safety data
  • Advanced stereo cameras to analyze surface-plume interactions (SCALPSS)
  • Laser retroreflector array (LRA) for precise cislunar positioning

The funding breakdown includes a $68.6 million base contract and a $79.7 million performance incentive for Intuitive Machines.

The company says the funding will allow it to create a standardized and repeatable "lunar utility pipeline" for delivering cargo to the moon.

"We are shifting the paradigm from custom aerospace engineering to commercial mass production of lunar infrastructure," Steve Altemus, CEO of Intuitive Machines, said in a separate news release. "Our flight-proven Nova-C platform allows us to build, test, and deploy multiple landers in parallel using Industry 4.0-powered manufacturing. This contract directly advances our core mission to provide persistent, reliable, and commercial baseline of transport, connectivity, and operations that allows our customers to stay longer and achieve more on the Moon."

NASA also shared that it is exploring plans to send PROMISE, a rover based on the Mars Perseverance and Curiosity rovers, to the moon and it plans to seek proposals for additional lunar lander missions, technology demonstrations, a communications and navigation satellite network, and new science payloads to support its lunar outpost. NASA is developing its Moon Base near the lunar South Pole. The agency expects it to come to fruition sometime after 2032.

Intuitive Machines had received its last CLPS award for $180.4 million in March 2026. It will be the first mission to utilize the company's larger cargo lunar lander, Nova-D. The company was also recently awarded a $1 million grant from Maryland Gov. Wes Moore to expand its robotics operations in the state.

UT team develops wearable technology for atmospheric water harvesting

In The Air

Engineers at the University of Texas at Austin have developed a prototype jacket that harvests clean drinking water directly from the atmosphere, and it works even in the driest desert conditions.

The research, published in Science Advances, marks the latest milestone in nearly a decade of work by materials scientist and chair professor Guihua Yu and his team at the Cockrell School of Engineering's Walker Department of Mechanical Engineering and Texas Materials Institute. The wearable technology marks a significant leap: instead of a bulky, stationary machine, this jacket does the work.

"We have been working on atmospheric water harvesting technology for a number of years," Yu says. "This current version is even more wearable. We're transitioning from conventional, more stationary water harvesting to something truly portable and personal."

Yu's lab first published work on hydrogel-based water harvesting around 2019, and the jacket is the latest evolution of that platform, now called AirGel. Last year, the broader AirGel invention won the top prize in the graduate category of the National Collegiate Inventors Competition.

The jacket is woven with specially engineered hydrogel fibers; ultra-porous materials that attract and absorb moisture from the surrounding air much like a household desiccant. Unlike a desiccant, the material doesn't require intense heat to release that water. The hydrogel is thermally responsive, meaning a modest rise in temperature — even from mild solar heating — is enough to release the water it has captured.

Condenser test in AustinSo, somebody would be wearing the jacket, or perhaps carrying this gel-like textile as a blanket, as it passively absorbs moisture from the air. Then they would detach the textile panels and place them into a small, portable collector unit; essentially a compact heater. The water evaporates out of the textile, condenses inside the collector, and drips out as clean, drinkable water.

"It immediately becomes drinkable because it already goes through the distillation process," Yu explains.

In trials, the jacket produced between 400 and 900 milliliters of water per day depending on humidity, or roughly 14-30 ounces, nearly a quart, depending on the air's humidity. With one kilogram of the textile, the researchers found they could generate approximately 3.7-4 liters of water in arid conditions, and potentially double that in humid ones. So far, the team has tried the jacket out in very dry, semi-dry, and humid areas, and the jacket was able to pull water from each climate.

Lead researcher Chuxin Lei, a postdoctoral researcher on Yu's team and co-author on the paper, says the goal was to rethink who this technology could serve.

Portable bag contents

"Many current [atmospheric water harvesting] systems are still built as rigid or stationary platforms, making them less suitable for people who are moving, working outdoors, or operating in some remote environment. This lead us to ask whether we could build a water harvesting system that could become more like clothing — light, wearable, flexible, and naturally suited for personal use," Lei says.

The potential applications are wide-ranging. Yu's team has previously worked with the Department of Defense on water solutions for soldiers, where water logistics can be dangerous and costly. The technology could also serve hikers, emergency responders, disaster relief workers, and agricultural and field workers. Anyone who needs clean water on the go and far from infrastructure.

The team also sees a potential future where the technology complements large-scale centralized water systems rather than replacing them.

"Our solution cannot be a universal solution for all," Yu acknowledges. "But I think it's an extremely important alternative."

For now, the jacket is still a laboratory prototype, but Yu and Lei are optimistic. With the right industry partnerships, they say, the technology could realistically reach commercial scale within three to five years.
