As the United States marks its 250th anniversary, a special collection in Science highlights the roots and evolution of the nation’s science and research enterprise.

 

Across three Policy Forums, authors illustrate how the United States’ scientific and technological progress has been driven not only by major discoveries and innovations, but also by the policies and institutions that supported them. These articles highlight the historical changes in government, universities, and industry that have shaped the U.S. research and science enterprise and emphasize that continued collaboration among these sectors is essential to advancing scientific research and technological development.

 

For much of U.S. history, the federal government played only a limited role in funding scientific research. However, in a Policy Forum by Daniel Gross and Bhaven Sampat, the authors discuss how that changed dramatically during World War II, when the government forged unprecedented partnerships with universities and industry to accelerate innovation for the war effort. This success ultimately laid the foundation for the modern American research enterprise as well as the establishment of the diverse network of federal science-focused agencies, such as the NIH, NSF, and NASA. The system that arose post-WWII has become globally influential and continues to fuel technological progress, economic growth, and public health.

 

In another Policy Forum, Johns Hopkins University President Ronald Daniels highlights the role of U.S. universities in U.S. research. According to Daniels, much of the modern American research enterprise can trace its roots to the late 19th century transformation of U.S. universities. The rise in advanced research through graduate-level education, which was sustained by federal investment, quickly made the U.S. a global leader in science. The author argues that the core principles of open competition, scientific merit, and academic freedom remain essential and should be strengthened rather than abandoned.

 

The final Policy Forum underscores how American industry has helped build American science and innovation. According to Ashish Arora and Sharon Belenzon, the organization of American innovation has evolved from the lone inventor to a collaborative ecosystem linking universities, start-ups, and established companies. Early industrial research laboratories, pioneered by innovators like Thomas Edison and later expanded by major corporations, integrated scientific discovery with product development and helped fuel many of the twentieth century’s greatest technological advances. Over time, however, universities became the primary engines of basic research, while venture-backed start-ups increasingly translated discoveries into commercial applications and larger firms focused on scaling them.

 

The package also includes a selection of six short essays from various authors that highlight the nation’s scientific legacy – both its extraordinary achievements, such as the space program, and its profound harms, like the eugenics movement. Together, the essays offer perspective on how science has shaped –  and been shaped by – democracy, equity, public investment, and the U.S.’s evolving values.

 

In an Editorial, Science Editor-in-Chief Holden Thorp reflects on whether the promise of knowledge and education envisioned by the founders is still alive in America today. “Rather than continuing to discuss the problem of public trust in higher education and science, the Semiquincentennial is an opportunity for both institutions to acknowledge that Americans can be disappointed in the impact of higher education and science on society but still believe that both can be better,” Thorp writes. “The scientific community can recognize this by committing to what it says it can do and living up to those aspirations in a way that is rigorously documented and provides benefits to all.”

Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter – as had previously been assumed – but also emit very faint radiation themselves. This radiation has not yet been observed in space; instead, researchers use models in the laboratory that mimic the behaviour of black holes. Although the effect of Hawking radiation is well known in astrophysics, the mechanism by which it arises in a gravitational context has not yet been fully elucidated. A scientist from Paderborn University is now shedding light on this mechanism using gravitational analogues in the laboratory. An international team of researchers from the Weizmann Institute of Science in Israel, Cinvestav in Mexico and Paderborn has achieved a breakthrough: They have theoretically modelled the process by which Hawking radiation is generated in a non-linear optical environment, identifying a simple, direct mechanism in the process. Furthermore, they were able to observe in experiments that the radiation affects the system. The results have now been published in the prestigious journal Nature.

Texas Tech University physicist Michael Fausnaugh is part of an international research team that used NASA’s TESS satellite in a new way to help confirm the existence of a distant "super Jupiter" exoplanet nearly 40,000 light-years from Earth. The discovery demonstrates the potential of using TESS observations to detect planets with gravitational microlensing. These planets more closely resemble those in our own solar system, expanding astronomers' ability to study previously hard-to-find worlds.

A new study led by Swansea University argues that the health benefits of nature-based healthcare may depend not only on access to green space, but also on the biodiversity and ecological quality of the environments involved.
