The pressure to be the perfect parent can be overwhelming, but social media and perceived world threats are causing some to be overprotective parents, and it is having a negative impact on our youth.

Researchers at Durham University have developed a new drone navigation system that enables autonomous aircraft to fly faster, more smoothly and more safely through crowded and obstacle-filled environments.

Executives increasingly turn to generative AI to help evaluate strategic decisions, from ranking business models to weighing competing options — but new research published in Strategic Management Journal cautions that no single AI-generated evaluation should be trusted at face value. The study finds that individual generative AI evaluations of strategic decisions are inconsistent and often biased, simply by the order in which two options are presented — but aggregating many evaluations across different prompts, roles, and models produces judgments that closely resemble those of human experts.

The research team of Anil R. Doshi of University College London, J. Jason Bell of the University of Oxford, and Emil Mirzayev and Bart Vanneste, both of University College London, tested large language models by having them rank 60 business models through pairwise comparisons, repeated across multiple models, ten assumed roles — including journalist, strategy professor, and industry expert — and two prompting strategies. No human expert panel evaluates the same option set that many ways, giving the researchers a rare way to measure where AI’s judgment holds up, and where it doesn’t.

To obtain support for novel business concepts, founders need to go beyond standard pitches, according to new research by Luis Martins, professor of management at the McCombs School of Business at The University of Texas at Austin.

What is required is what he calls fictional framing. It’s a narrative strategy that constructs a future world blending the real and imaginary. Though telling a story, it makes something drastically radical seem possible.

A new Landmark Perspective in Science marks the 50th anniversary of Robert C. Gallo, MD, and colleagues’ discovery of a human T-cell growth factor later named interleukin-2 (IL-2), a breakthrough that helped transform virology, immunology and cancer medicine.

The discovery made it possible to grow and maintain human T cells in culture, enabling research that led to the discovery of HTLV-1 and HTLV-2, the first human retroviruses, and contributing to the discovery and characterization of HIV and the development of the HIV blood test. IL-2 also became foundational to advances in cancer immunotherapy, including tumor-infiltrating lymphocyte (TIL) therapy and CAR-T cell therapy.

Written by Rafi Ahmed, PhD, and Steven A. Rosenberg, MD, PhD, the Science Landmark Perspective traces the far-reaching impact of the 1976 discovery and underscores the importance of sustained investment in fundamental research whose ultimate applications may not be apparent when the work begins.

The Global Virus Network, which Dr. Gallo co-founded, reflects on the discovery’s continuing scientific legacy and the role of international collaboration and basic science in enabling breakthroughs across disciplines and generations.
