Is it necessary to share ALL your data? Is transparency a good thing or does it make researchers “vulnerable,” as author Nathan Schneider suggests in the Chronicle of Higher Education article, “Why Researchers Shouldn’t Share All Their Data.”

Dark Data Defined

Dark data is defined as the universe of information an organization collects, processes and stores – oftentimes for compliance reasons. Dark data never makes it to the official publication part of the project. According to the Gartner Glossary, “storing and securing data typically incurs more expense (and sometimes greater risk) than value.”

This topic is reminiscent of the file drawer effect, a phenomenon which reflects the influence of the results of a study on whether or not the study is published. Negative results can be just as important as hypotheses that are proven.

Publication bias and the need to only publish positive research that supports the PI’s hypothesis, it can be argued, is not good science. According to an article in the Indian Journal of Anaesthesia, authors Priscilla Joys Nagarajan, et al., wrote: “It is speculated that every significant result in the published world has 19 non-significant counterparts in file drawers.” That’s one definition of dark data.

Total Transparency

But what to do with all your excess information that did not make it to publication, most likely because of various constraints? Should everything, meaning every little tidbit, be readily available to the research community?

Schneider doesn’t think it should be. In his article, he writes that he hides some findings in a paper notebook or behind a password, and he keeps interviews and transcripts offline altogether to protect his sources.

Open-source

Open-source software communities tend to regard total transparency as inherently good. What are the advantages of total transparency? You may make connections between projects that you wouldn’t have otherwise. You can easily reproduce a peer’s experiment. You can even become more meticulous in your note-taking and experimental methods since you know it’s not private information. Similarly, journalists will recognize this thought pattern as the recent, popular call to engage in “open journalism.” Essentially, an author’s entire writing and editing process can be recorded, step by step.

TMI

This trend has led researchers to open-source programs like Jupyter and GitHub. Open-source programs detail every change that occurs along a project’s timeline. Is unorganized, excessive amounts of unpublishable data really what transparency means? Or does it confuse those looking for meaningful research that is meticulously curated?

The Big Idea

And what about the “vulnerability” claim? Sharing every edit and every new direction taken opens a scientist up to scoffers and harassment, even. Dark data in industry even involves publishing salaries, which can feel unfair to underrepresented, marginalized populations.

In Model View Culture, Ellen Marie Dash wrote: “Let’s give safety and consent the absolute highest priority, with openness and transparency prioritized explicitly below those. This means digging deep, properly articulating in detail what problems you are trying to solve with openness and transparency, and handling them individually or in smaller groups.”

Houston surgeon takes part in first-of-its-kind surgery in space

remote control health care

A small surgical robot at the International Space Station completed its first surgery demo in zero gravity last week, and one of the surgeons tasked with the remote robotic operations on simulated tissue was Houston-based Dr. Theodoros Voloyiannis.

Voloyiannis took part in what is being referred to as “surgery in space” by being one of the six doctors remotely controlling spaceMIRA — Miniaturized In Vivo Robotic Assistant — that performed several operations on simulated tissue at the lab located in the space station. The surgeons operated remotely from earth in Lincoln, Nebraska. The remote surgeons worked to control the robot's hands to provide tension to the simulated tissue made of rubber bands. They then used the other hand to dissect the elastic tissue with scissors.

“I said during the procedure ‘it was a small rubber band cut, but a great leap for surgery,’“ Voloyiannis tells InnovationMap. “This was a huge milestone for me personally in my career.”

The robot was developed by Virtual Incision Corporation, and made possible through a partnership between NASA and the University of Nebraska. The team of surgeons took part in a demonstration that is considered a common surgical task, as they dissected the correct piece of tissue under pressure.

Latency is the time delay between when the command is sent and the robot receives it, and that was the big challenge the team faced. The delay was about 0.85 of a second according to what the colorectal surgeon who worked on spaceMIRA Dr. Michael Jobst said to CNN. The demo overall was a success according to the team, and posed a new-found adrenaline rush due to the groundbreaking innovation.

“The excitement of the new and the unknown,” Voloyiannis says on the feeling of doing the first operation of its kind. “I never thought I’d be doing something like this when I was in training and in medical school.”

Voloyiannis serves as the chairman of colon and rectal surgery for The US Oncology Network. He was chosen for this experiment due to his experience and expertise performing robotic colorectal surgery. Voloyiannis and the developers are hopeful that this type of technology will soon allow doctors to perform this specialized robotic surgery on patients living in rural areas without a specialized surgeon nearby, military battlefields, as well as regularly in space one day.

“The same concept of remote surgery regularly in space could certainly be entertained,” Voloyiannis says. “When you do things with an absence of gravity and perform a surgery in that environment — of course that changes the way we do things. When you have an absence of gravity with bodily fluids, it is a very hard surgery, but with partial gravity that idea can be entertained.

"Remotely, internet connectivity would have to be considered and you’d have someone remote like me here, while potentially there you’d have someone with less training doing the procedure there guiding the robot," he continues. "It’s quite the concept though.”

Houston geothermal startup secures $244M in funding round led by energy corporate

An Oklahoma-based shale oil and gas leader has backed Fervo Energy's latest round of funding, supporting the startup's geothermal technology yet again.

Fervo announced its latest round of funding this week to the tune of $244 million. The round was led by Devon Energy, a company that's previously backed the startup.

“Demand for around-the-clock clean energy has never been higher, and next-generation geothermal is uniquely positioned to meet this demand,” Tim Latimer, Fervo CEO and co-founder, says in a news release. “Our technology is fully derisked, our pricing is already competitive, and our resource pipeline is vast. This investment enables Fervo to continue to position geothermal at the heart of 24/7 carbon-free energy production.”

Founded in 2017, Fervo provides carbon-free energy through development of next-generation geothermal power. The company has recently reported its success at its Cape Station project, a400 MW project in Beaver County, Utah, as well as at its full-scale commercial pilot, Project Red, in northern Nevada and made possible through a 2021 partnership with Google.

Galvanize Climate Solutions, John Arnold, Liberty Mutual Investments, Marunouchi Innovation Partners, Mercuria, and Mitsubishi Heavy Industries also contributed to the round with existing investors Capricorn’s Technology Impact Fund, Congruent Ventures, DCVC, Elemental Excelerator, Helmerich & Payne, and Impact Science Ventures.

“The energy trilemma is one of the defining global challenges of our time; how can we generate power that is affordable, reliable, and clean,” Houstonian John Arnold, founder of Centaurus Capital and co-chair of Arnold Ventures, says in the release. “Fervo has transformed geothermal into a scalable carbon-free resource ready to meet the moment.”

The fresh funding, according to the company, will go toward Fervo’s work in Cape Station, that is slated to begin delivering clean electricity to the grid in 2026.

“Fervo’s approach to geothermal development leverages leading-edge subsurface, drilling, and completions expertise and techniques Devon has been honing for decades,” David Harris, chief corporate development officer and executive vice president at Devon, says in the release. “We look forward to deepening our partnership with Fervo to capture the full value of Fervo’s first-mover advantage in geothermal and the adjacencies to Devon’s core business.”

In 2022, Fervo raised a $138 million series C round to support the completion of power plants in Nevada and Utah and evaluate new projects in California, Idaho, Oregon, Colorado, and New Mexico, as well as in other countries. This latest investment brings the company's total funds raised to $431 million since its inception in 2017, according to Crunchbase.

3 Houston innovators to know this week

who's who

Editor's note: Welcome to another Monday edition of Innovators to Know. Today I'm introducing you to three Houstonians to read up about — three individuals behind recent innovation and startup news stories in Houston as reported by InnovationMap. Learn more about them and their recent news below by clicking on each article.

Scott Gale will be the first to admit that hosting a week of curated events targeted to a group of individuals within the tech and energy space isn't a novel idea — Climate Week NYC has been taking over Manhattan for over a decade. But Gale believes Houston deserves to have its own time to shine.

Earlier this month, Halliburton Labs, Rice Alliance, and Greentown Houston announced the inaugural Houston Energy and Climate Startup Week 2024 to take place in September, but Gale, executive director of Halliburton Labs, says he hopes this is just the beginning of Houston organizations coming together to collaborate on the initiative.

"I think we have a really awesome initial coalition. Whether your the fifth company or organization to raise its hand to do something that week or the 50th — it really doesn't matter," Gale says on the Houston Innovators Podcast. "It really is an open invitation — and I want to make that super clear." Read more.

In a new series of guest columna for InnovationMap, Jon Nordby is sharing his observations from years with working with founders.

"My top observation is that the success of founders often hinges on their focus on a specific problem, from the perspective of the problem holder (which is not always their customer) and particularly a problem set they care deeply about," he writes. "This focus is far more impactful than merely having a great idea. Founders with a laser focus on a problem, showed remarkable advantages."

Nordby is the managing partner at Anthropy Partners, a Houston-based investment firm, and professor of entrepreneurship at the University of Houston. Read more.
