Every researcher needs a Digital Persistent Identifier.

As a researcher, what is more important to you than a record of your research and scholarship? A Digital Persistent Identifier, or DPI, distinguishes you and your work from that of your peers – and having one will be mandated for those receiving federal funding. Let’s take a deeper look at why this number is so important. We’ll also compare the different platforms— ORCID, Web of Science, Scopus and Google Scholar — so that you can be sure your publications, presentations, peer reviews and even information about who is citing you are being properly stored and accessed.

ORCID

There are many types of profiles and DPIs that can meet your needs, but there’s no silver bullet. Placing your work onto multiple platforms is necessary according to Andrea Malone, Research Visibility and Impact Coordinator at UH Libraries. She cautions researchers to “be realistic about how many identifiers you can maintain.”

The most popular is ORCID, which stands for Open Researcher and Contributor ID. It’s free to set up, and there is no chance of accidentally or on-purpose having multiple ORCID accounts – it’s assigned to you like a social security number and follows you, the researcher. This comes in particularly especially handy for researchers with common names.

An identifier is federally mandated for those receiving governmental funds. It is not specified that ORCID must be that identifier. For example, according to Malone: “a Web of Science profile also assigns an identifier, which would also satisfy the mandate.” But most researchers choose ORCID because it’s publicly available with no access restrictions.

While an ORCID number is free for researchers, there is a subscription fee for an institution to be associated with ORCID. Information will not pre-populate in an ORCID profile and it doesn’t track citation counts – it only shows what you put in. There are, however, linking wizards that allow you to link from Web of Science and Scopus to your ORCID account. If you choose this option, citations will automatically populate in your ORCID profile. It’s up to the researcher to doublecheck to be sure the information has automated, however.

Google Scholar

Google Scholar is a profile, not an identifier, so it does not comply with federal funding requirements. It is free, however, and it pulls from the open web. You can choose to have your list of articles updated automatically, review the updates yourself or manually update your articles at any time. Google Scholar also specifies which articles are open access. A PDF or HTML icon will appear on the righthand side of each citation for one to download articles.

Web of Science Vs. Scopus

Scopus is known for covering more journals and a wider range of metrics to evaluate research impact than Web of Science. Different platforms are a go-to for certain disciplines – for example, Web of Science is usually associated with hard sciences, although investigators in the social sciences and humanities also place their work on this platform from time to time. It’s a good idea to check out which platforms others in your discipline are using for their profiles.

Staying up-to-date

Of course, DPIs don’t work as intended unless researchers keep their profiles current. That means you need to check your profile after every publication and every time you switch to a new institution. Just as you would update your CV, you must update your ORCID or other DPI profile.

One tactic Malone suggests is setting a schedule either biweekly or monthly to check all your profiles. “One thing that’s helpful is that with all of them, you can set up alerts and create an alert as often as you want,” Malone goes on. “At that time, the program will scrawl the content within the source and alert you to anytime any of your publications appear in their database.”

The Big Idea

No one tool can paint a complete picture of all your scholarship. Be strategic and intentional about which platforms you use. Consider your audience, the platforms others in your discipline use and make sure you have an ORCID profile to comply with the federal mandate. But be careful not to sign up for more than you can feasibly maintain and keep current.

Rice University lands $14M state grant to open Center for Space Technologies

on a mission

Rice University’s Space Institute soon will be home to the newly created Center for Space Technologies.

On Feb. 17, the Texas Space Commission approved a nearly $14.2 million grant for the Rice project. The Center for Space Technologies will target:

  • Research and development
  • Technology transfer and innovation
  • Statewide partnerships
  • Workforce development training
  • Space-focused education programs

The goal of the new center “is to fulfill an articulated need for research, workforce development, and industry collaboration,” said Kemah communications and marketing executive Gwen Griffin, chair of the commission.

State Rep. Greg Bonnen, a Friendswood Republican, authored the bill that set up the Texas Space Commission.

Since being authorized in 2023, the commission has funded 24 projects, with Rice and Houston-area companies accounting for nearly $75 million in grants to back space-related initiatives.

The grant to Rice brings the TSC's total investment to $150 million, fully committing the entire state appropriation from the Texas Legislature in 2023.

Other local companies that have received grants over the years include Aegis Aerospace, Axiom Space, Intuitive Machines, Starlab Space and Venus Aerospace.

The commission also awarded $7 million to Blue Origin earlier this month. See a list of the 24 awards here.

Waymo self-driving robotaxis have officially launched in Houston

Waymo has arrived

Waymo will begin dispatching its robotaxis in four more cities in Texas and Florida, expanding the territory covered by its fleet of self-driving cars to 10 major U.S. metropolitan markets.

The move into Dallas, Houston, San Antonio and Orlando, Florida, announced Tuesday, February 24, widens Waymo's early lead in autonomous driving while rival services from Tesla and the Amazon-owned Zoox are still testing their vehicles in only a few U.S. cities.

In contrast, Waymo's robotaxis already provide more than 400,000 weekly trips in the six metropolitan areas where they have been transporting passengers: Phoenix, the San Francisco Bay Area, Los Angeles, Miami, Atlanta, and Austin, Texas.

Waymo operates its ride-hailing service through its own app in all the U.S. cities except Atlanta and Austin, where its robotaxis can only be summoned through Uber's ride-hailing service.

The expansion into four more markets marks a significant step toward Waymo's goal to surpass 1 million weekly paid trips by the end of 2026. Without identifying where its robotaxis will be available next, Waymo is targeting a list of eight other cities that include Las Vegas, Washington, Detroit and Boston while signaling its first overseas availability is likely to be London.

To help pay for more robotaxis, Waymo recently raised $16 billion as part of the financial infusion that puts the value of the company at $126 billion. The valuation fueled speculation that Waymo may eventually be spun off from its corporate parent Alphabet, where it began as a secret project within Google in 2009.

Although Waymo is opening up in four more cities, its robotaxis initially will only be made available to a limited number of people with its ride-hailing app in Dallas, Houston, San Antonio and Orlando before the service will be available to all comers in those markets.

Tech giant Apple doubles down on Houston with new production facility

coming soon

Tech giant Apple announced that it will double the size of its Houston manufacturing footprint as it brings production of its Mac mini to the U.S. for the first time.

The company plans to begin production of its compact desktop computer at a new factory at Apple’s Houston manufacturing site later this year. The move is expected to create thousands of jobs in the Houston area, according to Apple.

Last year, the Cupertino, California-based company announced it would open a 250,000-square-foot factory to produce servers for its data centers in the Houston area. The facility was originally slated to open in 2026, but Apple reports it began production ahead of schedule in 2025.

The addition of the Mac mini operations at the site will bring the footprint to about 500,000 square feet, the Houston Chronicle reports. The New York Times previously reported that Taiwanese electronics manufacturer Foxconn would be involved in the Houston factory.

Apple also announced plans to open a 20,000-square-foot Advanced Manufacturing Center in Houston later this year. The project is currently under construction and will "provide hands-on training in advanced manufacturing techniques to students, supplier employees, and American businesses of all sizes," according to the announcement. Apple opened a similar Apple Manufacturing Academy in Detroit last year.

“Apple is deeply committed to the future of American manufacturing, and we’re proud to significantly expand our footprint in Houston with the production of Mac mini starting later this year,” Tim Cook, Apple’s CEO, said in the news release. “We began shipping advanced AI servers from Houston ahead of schedule, and we’re excited to accelerate that work even further.”

Apple's Houston expansion is part of a $600 billion commitment the company made to the U.S. in 2025.
