Brief Details About Inventions & Discoveries of 2025
In 2025, the world saw major breakthroughs in energy, space exploration, artificial intelligence, and biotechnology.
One of the most significant advancements was in fusion power. China’s EAST reactor set a new record by sustaining plasma for 1,066 seconds, but France’s WEST reactor soon surpassed it with 1,337 seconds—almost 22 minutes of continuous fusion. Meanwhile, private companies such as Helion, TAE Technologies, and Commonwealth Fusion Systems made massive strides. Helion raised $425 million to build a 50 MW fusion reactor for Microsoft by 2028. TAE Technologies secured $150 million in funding to test stable plasma at 70 million °C. Commonwealth Fusion Systems is progressing with its SPARC and ARC reactors, aiming to bring fusion to the grid by the early 2030s. In Germany, Proxima Fusion unveiled a compact stellarator design named "Stellaris" and raised €130 million. These efforts are being supported by the U.S. Department of Energy through its Fusion Milestone Program to accelerate the commercial rollout of fusion energy.
However, not all news was promising. The previously celebrated room-temperature superconductor, carbonaceous sulfur hydride (CSH), was officially retracted in 2025 after data was found to be fabricated. This setback reminded the scientific community of the importance of reproducibility and transparency in research.
In the field of space exploration, two new moons orbiting Jupiter were discovered, bringing the total to 97. Researchers also introduced the world’s smallest light-activated pacemaker and achieved laser cooling for data processors, promising greener and more efficient computing technologies.
Artificial intelligence played a growing role in scientific innovation. Researchers used AI to discover 19 new materials that could replace cement, offering a sustainable solution to reduce global carbon emissions. Meanwhile, new AI models like OpenAI's o3 and o4-mini were released, offering compact and efficient tools for developers and researchers.
These innovations reflect a global push towards cleaner energy, smarter technology, and deeper space knowledge. As we move forward, these breakthroughs in 2025 could shape the next decade of scientific and technological progress.
