A new study shows why some facilities cluster in cities for speed and access, while others move to rural regions in search of scale and lower costs. Based on research by Tommy Pan Fang (Rice Business) and Shane Greenstein (Harvard).

Key findings:

  • Third-party colocation centers are physical facilities in close proximity to firms that use them, while cloud providers operate large data centers from a distance and sell access to virtualized computing resources as on‑demand services over the internet.
  • Hospitals and financial firms often require urban third-party centers for low latency and regulatory compliance, while batch processing and many AI workloads can operate more efficiently from lower-cost cloud hubs.
  • For policymakers trying to attract data centers, access to reliable power, water and high-capacity internet matter more than tax incentives.

Recent outages and the surge in AI-driven computing have made data center siting decisions more consequential than ever, especially as energy and water constraints tighten. Communities invest public dollars on the promise of jobs and growth, while firms weigh long-term commitments to land, power and connectivity.

Against that backdrop, a critical question comes into focus: Where do data centers get built — and what actually drives those decisions?

A new study by Tommy Pan Fang (Rice Business) and Shane Greenstein (Harvard Business School) provides the first large-scale statistical analysis of data center location strategies across the United States. It offers policymakers and firms a clearer starting point for understanding how different types of data centers respond to economic and strategic incentives.

Forthcoming in the journal Strategy Science, the study examines two major types of infrastructure: third-party colocation centers that lease server space to multiple firms, and hyperscale cloud centers owned by providers like Amazon, Google and Microsoft.

Two Models, Two Location Strategies

The study draws on pre-pandemic data from 2018 and 2019, a period of relative geographic stability in supply and demand. This window gives researchers a clean baseline before remote work, AI demand and new infrastructure pressures began reshaping internet traffic patterns.

The findings show that data centers follow a bifurcated geography. Third-party centers cluster in dense urban markets, where buyers prioritize proximity to customers despite higher land and operating costs. Cloud providers, by contrast, concentrate massive sites in a small number of lower-density regions, where electricity, land and construction are cheaper and economies of scale are easier to achieve.

Third-party data centers, in other words, follow demand. They locate in urban markets where firms in finance, healthcare and IT value low latency, secure storage, and compliance with regulatory standards.

Using county-level data, the researchers modeled how population density, industry mix and operating costs predict where new centers enter. Every U.S. metro with more than 700,000 residents had at least one third-party provider, while many mid-sized cities had none.

ImageThis pattern challenges common assumptions. Third-party facilities are more distributed across urban America than prevailing narratives suggest.

Customer proximity matters because some sectors cannot absorb delay. In critical operations, even slight pauses can have real consequences. For hospital systems, lag can affect performance and risk exposure. And in high-frequency trading, milliseconds can determine whether value is captured or lost in a transaction.

“For industries where speed is everything, being too far from the physical infrastructure can meaningfully affect performance and risk,” Pan Fang says. “Proximity isn’t optional for sectors that can’t absorb delay.”

The Economics of Distance

For cloud providers, the picture looks very different. Their decisions follow a logic shaped primarily by cost and scale. Because cloud services can be delivered from afar, firms tend to build enormous sites in low-density regions where power is cheap and land is abundant.

These facilities can draw hundreds of megawatts of electricity and operate with far fewer employees than urban centers. “The cloud can serve almost anywhere,” Pan Fang says, “so location is a question of cost before geography.”

The study finds that cloud infrastructure clusters around network backbones and energy economics, not talent pools. Well-known hubs like Ashburn, Virginia — often called “Data Center Alley” — reflect this logic, having benefited from early network infrastructure that made them natural convergence points for digital traffic.

Local governments often try to lure data centers with tax incentives, betting they will create high-tech jobs. But the study suggests other factors matter more to cloud providers, including construction costs, network connectivity and access to reliable, affordable electricity.

When cloud centers need a local presence, distance can sometimes become a constraint. Providers often address this by working alongside third-party operators. “Third-party centers can complement cloud firms when they need a foothold closer to customers,” Pan Fang says.

That hybrid pattern — massive regional hubs complementing strategic colocation — may define the next phase of data center growth.

Looking ahead, shifts in remote work, climate resilience, energy prices and AI-driven computing may reshape where new facilities go. Some workloads may move closer to users, while others may consolidate into large rural hubs. Emerging data-sovereignty rules could also redirect investment beyond the United States.

“The cloud feels weightless,” Pan Fang says, “but it rests on real choices about land, power and proximity.”

Houston researcher tries to crack the code on the Fed's data to determine economic outlook

houston voices

Research by Rice Business Professor K. Ramesh shows that the Fed appears to harvest qualitative information from the accounting disclosures that all public companies must file with the Securities and Exchange Commission.

These SEC filings are typically used by creditors, investors and others to make firm-level investing and financing decisions; and while they include business leaders’ sense of economic trends, they are never intended to guide macro-level policy decisions. But in a recent paper (“Externalities of Accounting Disclosures: Evidence from the Federal Reserve”), Ramesh and his colleagues provide persuasive evidence that the Fed nonetheless uses the qualitative information in SEC filings to help forecast the growth of macroeconomic variables like GDP and unemployment.

According to Ramesh, the study was made possible thanks to a decision the SEC made several years ago. The commission stores the reports submitted by public companies in an online database called EDGAR and records the IP address of any party that accesses them. More than a decade ago, the SEC began making partially anonymized forms of those IP addresses available to the public. But researchers eventually figured out how to deanonymize the addresses, which is precisely what Ramesh and his colleagues did in this study.

"We were able to reverse engineer and identify those IP addresses that belonged to Federal Reserve staff," Ramesh says.

The team ultimately assembled a data set containing more than 169,000 filings accessed by Fed staff between 2005 and 2015. They quickly realized that the Fed was interested only in filings submitted by a select group of industry leaders and financial institutions.

But if Ramesh and his colleagues now had a better idea of precisely which bellwether firms the Fed focused on, they still had no way of knowing exactly what Fed staffers had gleaned from the material they accessed. So the team decided to employ a measure called "tone" that captures the overall sentiment of a piece of text – whether positive, negative, or neutral.

Building on previous research that had identified a set of words with negatively toned financial reports, Ramesh and his colleagues examined the tone of all the SEC filings accessed by Fed staff between one meeting of the Federal Open Markets Committee (FOMC) and the next. The FOMC sets interest rates and guides monetary policy, and its meetings provide an opportunity for Fed officials to discuss growth forecasts and announce policy decisions.

The researchers then examined the Fed's growth forecasts to see if there was a relationship between the tone of the documents that Fed staff examined in the period between FOMC meetings and the forecasts they produced in advance of those meetings.

The team found close correlations between the tone of the reports accessed by the Fed and the agency’s forecasts of GDP, unemployment, housing starts and industrial production. The more negative the filings accessed prior to an FOMC meeting, for example, the gloomier the GDP forecast; the more positive the filings, the brighter the unemployment forecast.

Ramesh and his colleagues also compared the Fed's forecasts with those of the Society of Professional Forecasters (SPF), whose members span academia and industry. Intriguingly, the researchers found that while the errors in the SPF's forecasts could be attributed to the absence of the tonal information culled from the SEC filings, the errors in the Fed’s forecasts could not. This suggests both that the Fed was collecting qualitative information that the SPF was not—and that the agency was making remarkably efficient use of it.

"They weren’t leaving anything on the table," Ramesh says.

Having solved one mystery, Ramesh would like to focus on another; namely, how does the Fed identify bellwether firms in the first place?

Unfortunately, the SEC no longer makes IP address data publicly available, which means that Ramesh and his colleagues can no longer study which companies the Fed is most interested in. Nonetheless, Ramesh hopes to use the data they have already collected to build a model that can accurately predict which firms the Fed is most likely to follow. That would allow the team to continue studying the same companies that the Fed does, and, he says, “maybe come up with a way to track those firms in order to understand how the economy is going to move.”

Houston researchers develop breakthrough device that could bypass spinal injuries

breakthrough research

Scientists at Houston Methodist have announced a significant leap forward for spinal cord injury recovery.

The researchers have developed a device that essentially bypasses spinal injuries, allowing signals from previously “lost” functions to reach the brain, a new study published in Nature Communications shows.

“Most current technologies try to improve whatever function remains after a spinal cord injury,” Dr. Damiano Barone, assistant professor of neurosurgery in the Department of Neurosurgery at Houston Methodist and co-lead on the study, said in a news release. “Our goal is different. Rather than fixing the injury itself, we want to bypass it completely and create an alternative route for signals to travel.”

The study involved a single ultrathin circumferential electrode array made to conform around the spinal cord without penetrating neural tissue, which was implanted into rodent and pig models with spinal injuries. The electrode array was able to interpret motor, sensory and autonomic signals around the injury. Think of it as a set of detours that restore road access to isolated towns after a disaster destroys the highway instead of just rebuilding the highway.

Over the course of three days, the arrays detected signals of intended movement from low-frequency spinal oscillations with more than 94 percent accuracy. This worked across species and was replicated in feasibility studies on human cadavers.

This research could serve as a new foundation for neuroprosthetic implants that could restore connectivity to the 2.5 million people worldwide suffering from spinal injuries that result in loss of ability. Future development could result in everything from restored organ function to mobility, according to Houston Methodist.

George Malliaras, the Prince Professor of Technology in the Department of Engineering at the University of Cambridge, who co-led the study, sees it as a fundamental restructuring of the science of spinal trauma.

“This could represent a paradigm change in how we think about spinal cord injuries,” Malliaras said. “Instead of starting from the idea that what is lost is gone forever, this approach asks whether we can restore function by carrying the signal around the injury.”

Further work involving laboratory models will need to be completed before launching human trials.

Grants from the National Institutes of Health, Houston Methodist Katz Investigator Award, Helaers Research Award and the Engineering and Physical Sciences Research Council helped support the study. Other collaborators on the study include Salim Hadwe, Ruben Serrano, George Psaltakis, Margaux Forner, Chaeyeon Lee, Sydney Swedick, Moleca Ghnnam, Tawfique Hasan and Alejandro Carnicer-Lombarte from the University of Cambridge; and Anton Banta and Xueer Zhang from Houston Methodist.

Abbott assembles expert team to help lure U.S. Space Academy to Texas

space race

State Rep. Greg Bonnen of Friendswood has been tapped to lead a new team that will promote Texas as the future home of the U.S. Space Academy.

Bonnen, a neurosurgeon, chairs Houston Physicians’ Hospital and the powerful Texas House Appropriations Committee. His House district is close to NASA’s Johnson Space Center.

Gov. Greg Abbott appointed the seven-member team. Last month, President Trump signed an executive order establishing the Presidential Commission on the U.S. Space Academy. Commission members, who held their first meeting this month, will recommend a permanent location for the academy.

Texas officials are pushing a site near Johnson Space Center to host the academy. Alabama, Colorado and Florida are among Texas’ competitors.

In a joint statement, U.S. Sen. Ted Cruz and U.S. Rep. Brian Babin, both of Texas, issued a statement backing the state’s bid for the academy. Cruz lives in Houston. Babbin lives in Woodville, about 55 miles south of Beaumont.

“America’s space program is built across the country, but Texas is where the pieces come together,” the lawmakers said. “We are ready to lead the next generation of space pioneers and look forward to showing why Texas is the right home for the U.S. Space Academy.”

The academy’s curriculum will include technical education, leadership development and public service components. Graduates will be set up for careers in the U.S. military, civil service, and aerospace sectors.

The Abbott-appointed team will work with the Texas Space Commission to prepare the state’s proposal for the academy.

In addition to Bonnen, team members with ties to Houston include:

  • Robert Ambrose, who grew up in Houston. He worked at Johnson Space Center before becoming associate director of the Texas A&M Space Institute.
  • Former NASA astronaut Nancy Curry-Gregg, director of the Texas A&M Space Institute. She earned a doctoral degree from the University of Houston and previously worked at Johnson Space Center.
  • Former NASA astronaut Jack Fischer, senior vice president of Houston-based Intuitive Machines. The company builds spacecraft, delivers payloads to the moon and launches satellites.

“Texas is the home of America’s human spaceflight program,” Abbott said in a release. “No state can match what Texas brings to this mission.”

“NASA’s Johnson Space Center, world-class universities, a premier commercial space industry, major military installations, and an unmatched aerospace workforce give Texas every asset the United States Space Academy requires,” the governor added.
