Core Insights - The article highlights seven significant scientific breakthroughs in 2025, showcasing advancements in gene editing, renewable energy, species protection, and disease control, which collectively instill confidence in the future of humanity [1]. Group 1: Species Protection - Several endangered species have shown significant population recovery in 2025, including the green sea turtle, which has been downgraded from "endangered" to "least concern" due to effective protection measures [5]. - The Antechinus, a small marsupial in Australia, has also recovered from near extinction to "least concern," with its habitat expanding by 48,000 square kilometers despite challenges like drought [5]. - The United Nations' High Seas Treaty, approved by over 60 countries, aims to protect biodiversity in international waters and secure at least 30% of land and marine areas [6]. Group 2: Ozone Layer Recovery - The Antarctic ozone hole has shrunk to its smallest size since 2019, indicating ongoing recovery of the Earth's protective upper atmosphere [7]. - The average annual size of the ozone hole has been decreasing since the 1987 Montreal Protocol, with hopes for complete recovery by the late 2060s if climate-friendly alternatives to chlorofluorocarbons are pursued [9]. Group 3: Gene Editing Advances - 2025 is marked as a breakthrough year for gene editing, with significant medical achievements including a Huntington's disease gene therapy that reduced cognitive decline by 75% [11]. - A CAR-T cell therapy for acute lymphoblastic leukemia showed substantial remission rates in clinical trials, and personalized CRISPR technology was tested for the first time on individuals [11][12]. - These advancements pave the way for developing mutation-specific strategies for rare diseases, highlighting collaboration between academia and industry [12]. Group 4: Renewable Energy Growth - Renewable energy surpassed coal for the first time in 2025, becoming the largest energy source globally, largely due to China's installation of 1 terawatt of solar power capacity [14]. - In the first half of 2025, China installed 256 gigawatts of solar systems, double the total installed in other regions [14]. - The EU sourced about half of its electricity from renewable energy in the second and third quarters, with expectations of nearly 4,600 gigawatts of renewable capacity added between 2025 and 2030 [16]. Group 5: Disease Control - The Ebola outbreak in the Democratic Republic of the Congo was contained within 42 days, with 64 reported cases, thanks to rapid response and vaccination efforts [18]. - The World Health Organization approved the first malaria treatment for infants, which could significantly reduce malaria deaths among children under five [20]. - A new anti-malarial drug, Ganaplacide-Lumefantrine, showed a 97.4% success rate in treating malaria in clinical trials, potentially becoming the first new anti-malarial drug approved since 1999 [20]. Group 6: Allergy Reduction - Research indicates a significant decrease in peanut allergy rates among American children, with a 43% reduction in prevalence among children under three compared to 2012 [22]. - The approach of introducing infants to peanut products at four months old has been shown to greatly reduce the likelihood of developing allergies [22].

Group 1 - The theme for this year's International Day for the Preservation of the Ozone Layer is "From Science to Global Action" [1] - China has made significant contributions to ozone layer restoration, having eliminated approximately 628,000 tons of ozone-depleting substances, accounting for over half of the total elimination in developing countries [1] - By the end of this year, China is expected to achieve an additional elimination of over 90,000 tons of ozone-depleting substances [1] Group 2 - The 40th anniversary of the Vienna Convention for the Protection of the Ozone Layer was commemorated, highlighting the importance of international cooperation in eliminating ozone-depleting substances [1] - The global effort is projected to restore the ozone layer to its pre-1980 levels by the middle of this century [1] - The Kigali Amendment is expected to help avoid a maximum of 0.5°C of global warming by the end of this century through the reduction of hydrofluorocarbons [1] Group 3 - China joined the Montreal Protocol in 1991 and accepted the Kigali Amendment in 2021, enhancing the control of non-CO2 greenhouse gases [2] - The Executive Secretary of the UN Environment Programme Ozone Secretariat stated that 99% of ozone-depleting substances have been eliminated globally, with China playing a leading role [2] - Starting July 1 next year, China will completely eliminate the use of hydrochlorofluorocarbons in three industries, ahead of schedule by three and a half years [2]
