Across the University of Houston campus, professors and researchers are creating solutions for various problems in several different industries.

From information technology benefiting police officers to stem cell-based pacemakers, here are three game-changing technologies coming out of UH.

A University of Houston associate professor of pharmacology is contributing to research that's taking stem cells found in fat and transforming them into heart cells to act as biologic pacemaker cells.

"We are reprogramming the cardiac progenitor cell and guiding it to become a conducting cell of the heart to conduct electrical current," says Bradley McConnell in a UH news release. McConnell's work can be found in the Journal of Molecular and Cellular Cardiology.

The treatment could replace the more than 600,000 electronic pacemakers implanted annually, These devices require regular doctors visits and aren't a permanent solution.

"Batteries will die. Just look at your smartphone," says McConnell. "This biologic pacemaker is better able to adapt to the body and would not have to be maintained by a physician. It is not a foreign object. It would be able to grow with the body and become much more responsive to what the body is doing."

Suchi Raghunathan, doctoral student in the UH Department of Pharmacological and Pharmaceutical Sciences in the College of Pharmacy, is the paper's first author, and Robert J. Schwartz, Hugh Roy and Lillian Cranz Cullen Distinguished Professor of biology and biochemistry, is another one of McConnell's collaborator.

The use of information technology to protect law enforcement

A tech-optimized police force is a safe police force, according to new UH research that shows that the use of information technology can cut down on the number of police officers killed or injured in the line of duty by as much as 50 percent.

"The use of IT by police increases the occupational safety of police officers in the field and reduces deaths and assaults against police officers," says C.T. Bauer College of Business Dean Paul A. Pavlou in a news release. Pavlou co-authored a paper on the research that was published in the journal Decision Support Systems.

Pavlou, along with his colleague, Min-Seok Pang of Temple University used FBI, the federal Bureau of Justice Statistics, and U.S. Census data to build a dataset, which tracked IT use and violence against law enforcement from 4,325 U.S. police departments over a six-year period, according to the release.

The study focused on crime intelligence, prediction, and investigation. The potential for IT in the police force had yet to be realized because there hadn't been much research on the subject.

A new solar energy capture and storage technology

New research coming out of UH has created a new and more efficient way to capture and store solar energy. Rather than using panels that store solar energy through photovoltaic technology, the new method, which is a bit of a hybrid, captures heat from the sun and stores it as thermal energy

The research, which was described in a paper in Joule, reports "a harvesting efficiency of 73% at small-scale operation and as high as 90% at large-scale operation," according to a news release.

The author of the paper, Hadi Ghasemi, is a Bill D. Cook Associate Professor of Mechanical Engineering at UH. He says the potential is greater due to the technology being able to harvest the full spectrum of sunlight. T. Randall Lee, Cullen Distinguished University Chair professor of chemistry, is also a corresponding author.

"During the day, the solar thermal energy can be harvested at temperatures as high as 120 degrees centigrade (about 248 Fahrenheit)," says Lee, who also is a principle investigator for the Texas Center for Superconductivity at UH. "At night, when there is low or no solar irradiation, the stored energy is harvested by the molecular storage material, which can convert it from a lower energy molecule to a higher energy molecule."

Building Houston

Call it the Bayou City Blues. A report from job website Lensa ranks Houston third among the U.S. cities with the unhappiest workers.

The report looks at four factors — vacation days taken, hours worked per week, average pay, and overall happiness — to determine the happiest and unhappiest cities for U.S. workers.

Lensa examined data for 30 major cities, including Dallas and San Antonio. Dallas appears at the top of the list of the cities with the unhappiest workers, and San Antonio lands at No. 8.

Minneapolis ranks first among the cities with the happiest workers.

Here's how Houston fared in the four ranking categories:

  • 16.6 million unused vacation days per year.
  • 40.1 average hours worked per week.
  • Median annual pay of $32,251.
  • Happiness score of out of 50.83.

Dallas had 19.4 million unused vacation days per year, 40.5 average hours worked per week, median annual pay of $34,479, and a happiness score of 53.3 out of 100.

Meanwhile, San Antonio had 5.7 million unused vacation days per year, 39.2 average hours worked per week, median annual pay of $25,894, and a happiness score of 48.61.

Texas tops Lensa's list of the states with the unhappiest workers.

"While the Lone Star State had a decent happiness score of 52.56 out of 100, it scored poorly on each of the other factors, with Texans allowing an incredible 67.1 million earned vacation days go to waste over the course of a year," Lensa says.

In terms of general happiness, Houston shows up at No. 123 on WalletHub's most recent list of the happiest U.S. cities. Dallas takes the No. 104 spot, and San Antonio lands at No. 141. Fremont, California, grabs the No. 1 ranking.
