Safety protocols are only as good as the Principal Investigators who enforce them and the students who adopt them. Operating a lab is no easy feat. It takes patience, consistency and teamwork. In an attempt to learn more about how PIs create a culture of safety, I reached to a few across our university campus to get some tips and tricks for creating effective safety procedures.

A PI’s guide to safety protocols

“My protocol is very clear, and students know the proper attire, but I had one student who arrived at the lab with shorts on. Apparently, he came from the gym … I guess he thought it was OK, but it’s definitely not,” said Mehmet Orman, assistant professor of Chemical and Biomolecular Engineering at the Cullen College of Engineering.

Orman’s research work aims to explore and analyze why some bacterial cells are stubborn to certain therapies. Currently, he uses E. Coli as a model organism to conduct his experiments. His research has the potential to uncover the best methods for combating drug resistant bacteria (aka “super bugs”) which is a seen by many researchers and health organizations as a global crisis.

With such important work, Orman must run a tight ship in his lab. When I spoke to him, he provided his best practices for lab safety.

1. Signage is key

Hazard communication is critical in the lab. “Signage is VERY important. we’ve had students leave Bunsen burners on, which is extremely hazardous. I have signs up everywhere reminding students to turn off the flame.”

2. Remind and repeat

The rule of thumb: you need to hear something 5-7 times for it to sink in. “My lab is new, and my students are young and still learning how to conduct themselves safely. I have to remind them of the protocol religiously, but I’d rather repeat something a million times than have an unfortunate incident occur.”

3. Tailor safety protocols to suit your lab

One size does not fit all when it comes to lab safety. “UH has wonderful, baseline safety protocol and resources for me to use, but every lab is different. I take the foundational information provided by the university and tailor it to fit the needs of my work.”

4. Take baby steps

Throwing students into the experimental deep end can be a big risk when it comes to safety. “Because I am a new researcher at UH and my students are new, I decided to take baby steps with my experiments. My work is about studying drug resistant bacteria, so I decided to begin my scientific exploration with E. coli, a less dangerous organism.” – No pseudomonas aeruginosa just yet.

5. Note to all students: Don’t be shy

“Over time, many of the students become friends. This becomes awkward if they witness their friend violating a safety rule. I encourage the students to speak up (even if it’s their friend), if they see something that threatens everyone’s safety. Everyone wins in the end.”

Safety is a part of the scientific process

Rachel Redfern, O.D., Ph.D., FAAO, is a UH faculty member and an active researcher. Her work focuses on ocular surface inflammation and the impact of contact lenses on normal and diseased eyes. With such sensitive work, safety in the lab is incredibly important to Redfern. She believes keeping her students safe begins at the top but depends on everyone in the lab.

“When students enter my lab, it’s my responsibility to create a safe space where they can perform experiments to answer their growing scientific questions,” said Redfern. “We work as a team to put safety first, but we’re all aware that everyone has different levels of lab safety experience – Every question (regarding safety) is a good one and the questions never asked are the dangerous ones.”

When asked how her students internalize a culture of safety, Redfern praised the education resources of the university.

“At UH, we have access to excellent training to promote a safe culture (shout out to Joe and the UH Environmental Health and Life Safety team!) and training is non-negotiable,” said Redfern. “Also, I often pair new students with seasoned students because setting a good example (among peers) is the best way to encourage students to follow safety practices during routine lab work.”

Eye on safety

When Redfern was a youngster in the lab, she learned that safety was critical to research.

“I was trained by scientists (and worked with peers) who view safety as an element of the scientific process,” said Redfern. “Fortunately, I haven’t been exposed to a ton of outrageous safety violations in my career; however, I have witnessed researchers smoking with latex gloves on and even eating in their dirty lab coats.”

At the end of the day, Redfern just wants to learn more about the complexities of the human eye and Orman wants to study super bugs and how to address a significant health issue. In order to do that, they must conduct experiments with the help of students in a safe environment. This takes team work, group and individual accountability, and everyone’s eye on safety.

When asked about his overall message to PIs and lab safety, Orman simply said, “We’re here for a purpose. We all must have each other’s back to stay safe and conduct meaningful research. It’s just how it is.”

University of Houston: Teamwork makes the dream work when it comes to lab safety

Houston voices

Getting along with colleagues and forming connections actually helps create a culture of lab safety.

For the most part, we all know how important it is to adhere to universal lab safety rules such as wearing closed-toe shoes or properly labeling all chemicals. Oftentimes, we forget about the human relations side of the safety equation. Cultivating positive working relationships with colleagues is as important (maybe even more so) as learning the “technical” safety rules of a lab. In this edition of the Big Bang, I will discuss the role of interpersonal relationship within the culture of safety.

During my exploration of this topic, I did not specifically find literature that directly links positive interpersonal relationships and lab safety. However, I spoke with a few UH scientists about this topic and I read articles about how to create a positive work environment in the lab in which a common theme arose – communication.

Moreover, the safest labs are operated by people who communicate well and have strong interpersonal relationships. Dr. Colin N. Haile, director of operations at the University of Houston Animal Behavior Core Facility agrees. He runs a complex lab where proper lab safety is vital to the care of the researchers and animals.

“Teamwork and healthy working relationships are extremely important to ensure our work is performed safely and of the best quality,” Dr. Haile said. “When colleagues respect and establish open communication, they are more compelled to help one another adhere to safety protocols.”

Getting along with others is easy, right?

Getting along with others is not easy. We all have diverse backgrounds, life experiences, points of view and expertise. Consequently, the occasional clash with a colleague is not always avoidable.

Frequent showdowns cause disruptions in team morale, productivity and could be a catalyst for an unsafe science lab. In addition to cultivating open communication, there are a few other ways to maintain positive relationships in the lab that contribute to a culture of safety.

Tips for developing and maintaining positive working relationships in your science lab

  • Communication is king & clarity and concision is queen – Communicate exactly what you want and need in a clear, concise manner, especially if there’s a safety issue to address. Also, try to give your email a break – talk to you colleagues face-to-face. This may avoid miscommunication and builds a personal rapport and camaraderie with your teammate.
  • Be nice and respect others – This one is obvious, but important to mention. Stronger bonds and trust is created when you are friendly to colleagues…Hey, you can even take things a step further and show an interest in a co-worker’s family or hobbies outside of the lab. Again, building personal rapport instills trust amongst the group which contributes to safer work environments
  • Keep an open mind and consider diverse points of view – As mentioned earlier, our world is colorful and diverse. That’s what makes humans unique and interesting. Everyone comes from different walks of life and bring unique points of view to their place of business. Preserving superior interpersonal relationships requires colleagues to listen, understand and exhibit compassion towards each other’s points of view. When people are heard, they feel appreciated and possess the motivation to help keep their work space functional and safe.

Strong team = Safer labs and maybe a few cool, new science discoveries

Of course, I’m not suggesting 24-hour Kumbaya in the lab, but the concept of getting along is certainly one that encourages lab safety. Strong teams discover the greatest breakthroughs and are safer in the lab because trust, open communication and respect are established. Well, that’s it for this edition of the Big Bang. Until next time…Be well and stay safe!

Rice University researchers unveil new model that could sharpen MRI scans

MRI innovation

Researchers at Rice University, in collaboration with Oak Ridge National Laboratory, have developed a new model that could lead to sharper imaging and safer diagnostics using magnetic resonance imaging, or MRI.

In a study recently published in The Journal of Chemical Physics, the team of researchers showed how they used the Fokker-Planck equation to better understand how water molecules respond to contrast agents in a process known as “relaxation.” Previous models only approximated how water molecules relaxed around contrasting agents. However, through this new model, known as the NMR eigenmodes framework, the research team has uncovered the “full physical equations” to explain the process.

“The concept is similar to how a musical chord consists of many notes,” Thiago Pinheiro, the study’s first author, a Rice doctoral graduate in chemical and biomolecular engineering and postdoctoral researcher in the chemical sciences division at Oak Ridge National Laboratory, said in a news release. “Previous models only captured one or two notes, while ours picks up the full harmony.”

According to Rice, the findings could lead to the development and application of new contrast agents for clearer MRIs in medicine and materials science. Beyond MRIs, the NMR relaxation method could also be applied to other areas like battery design and subsurface fluid flow.

“In the present paper, we developed a comprehensive theory to interpret those previous molecular dynamics simulations and experimental findings,” Dilipkumar Asthagiri, a senior computational biomedical scientist in the National Center for Computational Sciences at Oak Ridge National Laboratory, said in the release. ”The theory, however, is general and can be used to understand NMR relaxation in liquids broadly.”

The team has also made its code available as open source to encourage its adoption and further development by the broader scientific community.

“By better modeling the physics of nuclear magnetic resonance relaxation in liquids, we gain a tool that doesn’t just predict but also explains the phenomenon,” Walter Chapman, a professor of chemical and biomolecular engineering at Rice, added in the release. “That is crucial when lives and technologies depend on accurate scientific understanding.”

The study was backed by The Ken Kennedy Institute, Rice Creative Ventures Fund, Robert A. Welch Foundation and Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory.

Luxury transportation startup connects Houston with Austin and San Antonio

On The Road Again

Houston business and leisure travelers have a luxe new way to hop between Texas cities. Transportation startup Shutto has launched luxury van service connecting San Antonio, Austin, and Houston, offering travelers a comfortable alternative to flying or long-haul rideshare.

Bookings are now available Monday through Saturday with departure times in the morning and evening. One-way fares range from $47-$87, putting Shutto in a similar lane to Dallas-based Vonlane, which also offers routes from Houston to Austin and San Antonio.

Shutto enters the market at a time when highway congestion is a hotter topic than ever. With high-speed rail still years in the future, its model aims to provide fast, predictable service at commuter prices.

The startup touts an on-time departure guarantee and a relaxed, intimate ride. Only 12 passengers fit inside each Mercedes Sprinter van, equipped with Wi-Fi and leather seating. And each route includes a pit stop at roadside favorite Buc-ee's.

In announcing the launch, founder and CEO Alberto Salcedo called the company a new category in Texas mobility.

“We are bringing true disruptive mobility to Texas: faster and more convenient than flying (no security lines, no delays), more comfortable and exclusive than the bus or train, and up to 70 percent cheaper than private transfers or Uber Black,” Salcedo said in a release.

“Whether you’re commuting for business, visiting family, exploring Texas wineries, or doing a taco tour in San Antonio, Shutto makes traveling between these cities as easy and affordable as riding inside the city."

Beyond the scheduled routes, Shutto offers private, customizable trips anywhere in the country, a service it expects will appeal to corporate retreat planners, party planners, and tourists alike.

In Houston, the service picks up and drops off near the Galleria at the Foam Coffee & Kitchen parking lot, 5819 Richmond Ave.. In San Antonio, it is located at La Panadería Bakery’s parking lot at 8305 Broadway. In Austin, the location is the Pershing East Café parking lot at 2501 E. Fifth St.

Houston-area lab grows with focus on mobile diagnostics and predictive medicine

mobile medicine

When it comes to healthcare, access can be a matter of life and death. And for patients in skilled nursing facilities, assisted living or even their own homes, the ability to get timely diagnostic testing is not just a convenience, it’s a necessity.

That’s the problem Principle Health Systems (PHS) set out to solve.

Founded in 2016 in Clear Lake, Texas, PHS began as a conventional laboratory but quickly pivoted to mobile diagnostics, offering everything from core blood work and genetic testing to advanced imaging like ultrasounds, echocardiograms, and X-rays.

“We were approached by a group in a local skilled nursing facility to provide services, and we determined pretty quickly there was a massive need in this area,” says James Dieter, founder, chairman and CEO of PHS. “Turnaround time is imperative. These facilities have an incredibly sick population, and of course, they lack mobility to get the care that they need.”

What makes PHS unique is not only what they do, but where they do it. While they operate one of the largest labs serving skilled nursing facilities in the state, their mobile teams go wherever patients are, whether that’s a nursing home, a private residence or even a correctional facility.

Diagnostics, Dieter says, are at the heart of medical decision-making.

“Seventy to 80 percent of all medical decisions are made from diagnostic results in lab and imaging,” he says. “The diagnostic drives the doctor’s or the provider’s next move. When we recognized a massive slowdown in lab results, we had to innovate to do it faster.”

Innovation at PHS isn’t just about speed; it’s about accessibility and precision.

Chris Light, COO, explains: “For stat testing, we use bedside point-of-care instruments. Our phlebotomists take those into the facilities, test at the bedside, and get results within minutes, rather than waiting days for results to come back from a core lab.”

Scaling a mobile operation across multiple states isn’t simple, but PHS has expanded into nine states, including Texas, Oklahoma, Kansas, Missouri and Arizona. Their model relies on licensed mobile phlebotomists, X-ray technologists and sonographers, all trained to provide high-level care outside traditional hospital settings.

The financial impact for patients is significant. Instead of ambulance rides and ER visits costing thousands, PHS services often cost just a fraction, sometimes only tens or hundreds of dollars.

“Traditionally, without mobile diagnostics, the patient would be loaded into a transportation vehicle, typically an ambulance, and taken to a hospital,” Dieter says. “Our approach is a fraction of the cost but brings care directly to the patients.”

The company has also embraced predictive and personalized medicine, offering genetic tests that guide medication decisions and laboratory tests that predict cognitive decline from conditions like Alzheimer's and Parkinson’s.

“We actively look for complementary services to improve patient outcomes,” Dieter says. “Precision medicine and predictive testing have been a great value-add for our providers.”

Looking to the future, PHS sees mobile healthcare as part of a larger trend toward home-based care.

“There’s an aging population that still lives at home with caretakers,” Dieter explains. “We go into the home every day, whether it’s an apartment, a standalone home, or assisted living. The goal is to meet patients where they are and reduce the need for hospitalization.”

Light highlighted another layer of innovation: predictive guidance.

“We host a lot of data, and labs and imaging drive most treatment decisions,” Light says. “We’re exploring how to deploy diagnostics immediately based on results, eliminating hours of delay and keeping patients healthier longer.”

Ultimately, innovation at PHS isn’t just about technology; it’s about equity.

“There’s an 11-year life expectancy gap between major metro areas and rural Texas,” Dieter says. “Our innovation has been leveling the field, so everyone has access to high-quality diagnostics and care, regardless of where they live.”
