As the world looks ahead to 2026, the scientific landscape is set to undergo significant changes. This year presents an opportunity not only to anticipate future advancements, but also to reflect on the challenges that have shaped federally funded scientific research in recent years. Despite the pressures and dismissals that have affected the field, dedicated individuals continue to ensure the integrity of scientific exploration. Here are some key areas to watch in the coming year.
Nuclear Energy
The United States is on the brink of a pivotal shift in its energy strategy, focusing on expanding nuclear power to meet the escalating demands driven by the artificial intelligence boom. While wind, solar, and natural gas have dominated recent years, recent legislative efforts such as the 2024 law streamlining reactor licensing, alongside initiatives by both the Biden and Trump administrations to export and finance nuclear technology, are set to rejuvenate this sector. However, as advanced technology projects progress, concerns about safety, nuclear waste management, and proliferation risks persist.
Meanwhile, the geopolitical landscape is tense following the U.S. bombing of Iran’s nuclear sites in June 2025, reviving cold-war era fears and affecting the renewal of nuclear treaties like New START with Russia.
Disaster Response
Changes in disaster response policy are underway as the Trump administration aims to reduce federal involvement by downsizing FEMA and shifting responsibilities to local authorities. This shift has sparked controversy, as officials have fired or suspended FEMA staffers who opposed these downsizing measures. The efficacy of this approach will be tested in the event of a major disaster in 2026, especially since recent years have seen catastrophic events that overwhelmed existing resources.
Space
The lunar frontier remains a focal point for space exploration, with NASA’s Artemis II mission scheduled for launch in February, marking the first crewed mission to the moon in over 50 years. In parallel, commercial entities like SpaceX and Firefly Aerospace are conducting test flights and satellite deployments. Internationally, China, India, and Japan are pushing boundaries with ambitious missions involving new telescopes and Martian exploration.
Health and Medicine
The landscape of health and medicine in the U.S. is at a crossroads, with budget cuts affecting public health agencies’ ability to track and respond to health crises. Amid declining vaccination rates and eroding trust in public health experts, concerns mount about the resurgence of diseases like measles and polio. Conversely, 2026 could witness breakthroughs in therapies for autoimmune diseases and cancer, building on recent Nobel Prize-winning advances in T cell therapy.
Conservation
The federal government’s proposal to redefine “harm” in the Endangered Species Act could ease restrictions on developments in habitats critical to endangered species. Simultaneously, misleading claims from companies like Colossal Biosciences regarding de-extinction efforts could undermine conservation efforts, highlighting the need for public support to protect vulnerable species.
Artificial Intelligence and Technology
The ongoing debate over data privacy laws in the U.S. is reaching a critical juncture. With technology companies amassing vast amounts of personal data, the push for comprehensive legislation like the American Privacy Rights Act is gaining momentum. Such laws are essential to protect consumers and ensure fair competition in the tech industry.
Information Sciences
Book censorship remains a contentious issue, with thousands of bans reported across the U.S. since 2021. Organizations like PEN America and its allies are actively resisting these efforts, while the rise of AI-generated content challenges traditional notions of authorship and creativity.
