ScienceDirect 25 years of Discovery

Where were you in 1999?

While the world prepared for Y2K, science, technology and medicine experienced:

  • Successful mapping of the entire genetic code of a single human chromosome

  • Birth of the six billionth human being

  • 3D mapping of Mars

  • Founding of Alibaba

  • Launch of ScienceDirect

This year, 2024, marks a milestone in ScienceDirect’s distinguished history: the celebration of 25 years of research, scholarship and discovery.


As the needs of scholars, researchers and librarians, their ecosystems and the technologies they use have changed since its launch, ScienceDirect continues to support their work by:

  • Expanding literature formats beyond journal articles

  • Broadening subject coverage

  • Developing tools that enhance the user experience

  • Updating technologies that simplify access and workflows

  • Embracing reporting standards, accessibility and open access

  • And we are poised to do even more in the months and years ahead.

25 years of positive research outcomes and improving the lives of many

Throughout our 25-year journey, we've amassed a wealth of remarkable and inspiring research stories from our users, each overcoming formidable challenges on their road to success.

Included here are three such stories, as well as links to the related research published on ScienceDirect. All three researchers were honored among the winners of the 2021 OWSD-Elsevier Foundation Award for Early Career Women Scientists in the Developing World.

Finding toxic substances in unusual places

For Prof. Marian Asantewah Nkansah, who specializes in environmental chemistry, circumstances continually remind her that science comes with a price tag. Scientists everywhere face this reality, but for those in developing countries, the situation can be even more palpable. “Toxic substances can be found in unusual places,” she explains. “So, I look in places where many scientists don’t go looking.”

Marian is an Associate Professor in the Department of Chemistry at the Kwame Nkrumah University of Science and Technology (KNUST) in Kumasi, Ghana. There, she teaches Practical Chemistry, Nuclear/Radiochemistry, Chemistry and Society, Petroleum Chemistry, and Research Methods.

How science can help feed the future

Eugénie Kayitesi spent the first seven years of her life moving from one refugee camp to another as she and her parents fled the civil war in Uganda. She experienced first-hand the devastating effects caused by not having enough food.

This experience led her to the path she is on today. Through her research, Eugénie hopes to improve nutrition, diet and food security in Africa and beyond.

Eugénie is an Associate Professor in the Department of Consumer and Food Sciences at the University of Pretoria South Africa. She has published more than 30 peer-reviewed international journal articles and book chapters, received multiple awards and is a World Academy of Science (TWAS) Young Affiliate.

From curious to award-winning

When Dr. Ghada Dushaq was a child, nothing was safe from her prying mind and fingers. If there was a remote control on the coffee table, she would take it apart to figure out how it worked.

In second grade, her curiosity got on her teacher’s nerves.

“She complained to my mom that I was asking too many questions,” Ghada recalled. “‘Why does a banana have no seeds? If you say that our shadow is like a mirror, why don’t we see the exact color? … ‘I don’t know how to answer her.’”

Fortunately, her parents were educators who encouraged her exploration. Today, she continues her exploration as a Postdoctoral Associate in the Photonics Research Lab at NYU Abu Dhabi. Through her research, she is coming up with new and innovative materials for high-speed optical communications.
