CNPEM<\/span>Sirius, Brazil\u2019s largest research facilityCNPEM<\/span><\/p><\/div>\n

Without purporting to be a definitive list of the most important discoveries and breakthroughs from the last 25 years, this special edition of Pesquisa FAPESP<\/em> highlights 25 standout scientific and technological milestones\u2014both in Brazil and globally\u2014that have had a significant impact on the course of research and innovation since this magazine\u2019s launch 25 years ago. Given their limitations, lists like these are inherently non-exhaustive and subject to debate. Impactful breakthroughs have inevitably been left out, while some of those listed, some might argue, may not warrant inclusion. With that said, the aim of this list is to show how science can evolve and redefine human knowledge in a relatively short space of time.<\/p>\n

Sirius: synchrotron light and the structure of matter<\/strong>
\nThe Sirius particle accelerator, the largest and most complex science facility ever built in Brazil<\/a>, was launched in November 2018 at the Brazilian Center for Research in Energy and Materials (CNPEM), just 15 kilometers from Campinas, S\u00e3o Paulo. A particle accelerator is a machine used to generate synchrotron radiation, a special type of light source that, like a giant microscope, enables scientists to investigate the structure of matter at the atomic and molecular level. Built at an estimated cost of about R$2 billion, Sirius is still not fully completed, with 6 of its 14 experimental stations currently operational.<\/p>\n

Complex societies in the Amazon<\/strong>
\nRecent archaeological research in the Amazon has revealed that this vast rainforest may once have been home to highly developed, complex societies<\/a> with populations numbering in the millions during precolonial times. Evidence such as large interconnected villages, roads, and the presence of dark earths\u2014a type of fertile soil linked to long-term human occupation\u2014supports this new view. Some findings even suggest that the Amazon rainforest was once a managed environment, shaped by Indigenous peoples for centuries, rather than a pristine natural biome.<\/p>\n

NIH<\/span>Sequencing the first human genome took more than a decade and billions of dollarsNIH<\/span><\/p><\/div>\n

Human genome sequencing<\/strong>
\nOn February 12, 2001, two of the world\u2019s top scientific journals, Nature<\/em> and Science<\/em>, published drafts of the full human genome sequence, produced by two independent and competing groups: an international public consortium and a private US company, Celera. The public initiative took over a decade and cost US$2.7 billion to complete. This led to a wave of genomic research and technology in the decades that followed. Today, sequencing an individual\u2019s DNA takes just a few hours<\/a> and costs around US$600.<\/p>\n

Flex-fuel cars propel mobility in Brazil<\/strong>
\nThe commercial debut of Brazil\u2019s first flex-fuel car in March 2003 revolutionized the country\u2019s passenger car market. Flex-fuel vehicles can uniquely run on gasoline, ethanol, or any blend of both. As of 2023, flex-fuel cars made up over 76% of Brazil\u2019s vehicle fleet. When running on ethanol, they generate less emissions compared to those running on gasoline.<\/p>\n

The birthplace of dinosaurs<\/strong>
\nAlong with Argentina, Brazil has, in the last two decades, emerged as one of the top sites on Earth for discovering the most ancient dinosaur fossils. These finds have made South America a likely candidate for the birthplace of dinosaurs, which went extinct 65 million years ago. At least six species of dinosaurs, dating back over 230 million years, have been uncovered in the Santa Maria geological formation in Rio Grande do Sul<\/a>. Five of these six species were discovered after 1999. The largest measured 2.5 meters in length and stood about waist-high to an adult human.<\/p>\n

The rise of artificial intelligence
\n<\/strong>In late 2022, the general public was first introduced to a field of research that had been quietly evolving in academia and tech companies for years: generative artificial intelligence (AI)<\/a>. The commercial release of ChatGPT, developed by US startup OpenAI, sparked a wave of both excitement and fear. While prone to error, the system can generate coherent text based on user prompts and simulate human-like conversations. Other AI tools soon followed, including some that can produce images and videos.<\/p>\n
