The year 2025 has been a tumultuous one for science, with political upheaval in the United States causing funding cuts, academic layoffs, and vaccine-sceptic policies that have been widely criticized as an attack on science. The repercussions of these actions are expected to have lasting effects on the scientific community for years to come. Despite these challenges, there have also been many positive developments in the world of science that offer hope for the future.
One of the most significant success stories of 2025 has been the recovery of endangered and near-extinct species. Conservation efforts have led to populations of species like the green sea turtle and the ampurta, an Australian marsupial, bouncing back from the brink of extinction. Additionally, nations around the world reached a historic milestone for marine conservation with the approval of the United Nations High Seas Treaty, which aims to protect biodiversity in international waters and conserve at least 30% of land and sea areas.
Another positive development in 2025 was the shrinking of the ozone hole in the Antarctic. This progress is a result of international efforts to phase out ozone-depleting chlorofluorocarbons (CFCs) through agreements like the Montreal Protocol. Continued efforts to find climate-friendly alternatives to CFCs are expected to lead to the complete recovery of the ozone hole by the late 2060s.
Gene-editing technologies also saw significant advances in 2025, with breakthroughs in medical milestones. Clinical trials for gene therapies targeting diseases like Huntington’s disease and T-cell acute lymphoblastic leukemia showed promising results, with participants experiencing significant improvements in their conditions. These successes paved the way for the development of mutation-specific strategies for rare diseases, demonstrating the potential of gene editing to revolutionize healthcare.
Renewable energy also saw a major boost in 2025, with China surpassing coal as the largest energy source globally for the first time. The country installed a record amount of solar power capacity and plans to continue expanding its renewable energy infrastructure in the coming years. Other regions, like the European Union, also made significant strides in increasing their renewable energy capacity, with projections showing a substantial increase in renewable energy deployment by 2030.
Finally, in September, health workers and African governments successfully contained an outbreak of Ebola in the Democratic Republic of the Congo in just 42 days. This rapid response to the outbreak showcased the effectiveness of coordinated efforts in combating infectious diseases and preventing widespread outbreaks.
Overall, despite the challenges faced by the scientific community in 2025, there have been many positive developments that offer hope for the future of science and the world at large. From species recovery to advances in gene editing and renewable energy, these success stories highlight the resilience and innovation of the scientific community in the face of adversity. In a recent update, it has been reported that a total of 64 cases of Ebola were reported, with the last case being recorded on 25 September. Despite the challenges posed by the remote locations of these areas, responders were able to contain the virus and prevent its spread, according to Henry Kyobe Bosa, who leads the Ebola and COVID-19 response for Uganda’s Ministry of Health.
Following the outbreak declaration, vaccination roll-out and treatment with monoclonal antibody therapy were initiated promptly, which played a crucial role in preventing severe illness. Bosa emphasized the improvements in management, response, community engagement, and contact tracing that contributed to the successful containment of the outbreak.
In other health news, the World Health Organization (WHO) recently approved the first malaria treatment specifically designed for infants. Given that children under the age of five account for a significant percentage of malaria-related deaths globally, this new medication, called Coartem (artemether-lumefantrine), could potentially help in reducing the burden of the disease and moving closer towards its elimination. Jane Achan, a pediatrician specializing in infectious diseases, highlighted the significant implications of this new treatment for improving outcomes in at-risk populations, especially infants and young children.
Additionally, a phase III clinical trial conducted this year demonstrated promising results for a new malaria drug called ganaplacide-lumefantrine (GanLum). The drug showed a success rate of 97.4% in treating malaria and was effective against parasites that have developed resistance to existing antimalarial medications. If GanLum receives regulatory approval, it will mark the first new class of malaria medicine in over 25 years, bringing hope for improved treatment options.
In a positive development related to food allergies, a study revealed a significant decrease in peanut allergies among children in the United States over the past decade. This decline is attributed to a shift in guidelines that now recommend early exposure to peanut products in infants, contrary to previous advice. The study showed a 43% reduction in peanut allergy prevalence in children under three, as well as a 36% decrease in other food allergies, following the revised guidelines.
“This is a good year to have a peanut allergy or a food allergy,” remarked Michael Pistiner, a pediatric allergist, highlighting the positive impact of evidence-based policy changes on public health outcomes. The success in reducing peanut allergies serves as a testament to the importance of translating research findings into practical guidelines for the broader community.
As we reflect on these recent health advancements, it is evident that ongoing research, effective policies, and timely interventions play a crucial role in improving health outcomes and addressing public health challenges.
