Exploring groundbreaking discoveries from Mars to microbiology that are shaping our future
The National Academy of Sciences awards represent the pinnacle of scientific achievement, recognizing extraordinary contributions that expand human knowledge and address fundamental questions about our world and universe.
Honoring scientists who push the boundaries of their fields
Celebrating work that transforms our understanding of the natural world
Advancing science for the betterment of humanity
The National Academy of Sciences was established in 1863 under a congressional charter signed by President Abraham Lincoln, providing independent, objective advice to the nation on matters related to science and technology.
The Public Welfare Medal stands as one of the most distinguished NAS honors, recognizing extraordinary use of science for the public good.
Recognized for groundbreaking work spanning medical genetics and human rights, including identifying the BRCA1 gene and using genetics to reunite families torn apart by violence.
Mary-Claire King's career demonstrates how scientific excellence and social responsibility converge to transform both individual lives and entire fields of medicine.
The 2025 NAS awards celebrate discoveries that have advanced fundamental understanding across the scientific spectrum.

A groundbreaking investigation that may bring us closer than ever to answering the profound question: Are we alone in the universe?
NASA's Perseverance rover, exploring the Jezero Crater on Mars, arrived at an intriguing location in July 2024—the "Bright Angel" formation, part of an ancient river delta 7 . Scientists hypothesized that this area, once flowing with water, might preserve evidence of ancient microbial life if it ever existed on Mars.
The rover used its drill to collect a core sample from a rock named "Cheyava Falls" 7 .
Perseverance's PIXL and SHERLOC instruments scanned the rock, identifying unusual colorful spots 7 .
Instruments revealed a distinct pattern of minerals arranged into "leopard spots" 7 .
Spectroscopic analysis identified vivianite and greigite in these spots 7 .
| Parameter | Finding | Biological Significance |
|---|---|---|
| Mineral Composition | Vivianite and greigite | On Earth, vivianite is found around decaying organic matter; some microbes produce greigite 7 |
| Geological Context | Sedimentary rock composed of clay and silt | Excellent preserver of microbial life on Earth 7 |
| Chemical Composition | Rich in organic carbon, sulfur, oxidized iron, and phosphorus | These compounds could have been a rich energy source for microbial metabolisms 7 |
| Formation Pattern | "Leopard spots" showing reaction fronts | Pattern consistent with electron-transfer reactions used by microbes for energy 7 |
| Environmental History | No evidence of high temperatures or acidic conditions | Rules out some abiotic formation mechanisms for the minerals 7 |
"The combination of these findings—particularly the specific mineral pairing in a pattern suggesting biological energy-production mechanisms—makes this finding particularly compelling."
This discovery has fundamentally shifted our understanding of Mars' potential habitability. The finding in some of the youngest sedimentary rocks the mission has investigated suggests Mars could have been habitable for longer—or later in its history—than previously thought 7 .
The sample is now part of Perseverance's collection, awaiting possible return to Earth through a future mission where more powerful laboratory equipment could provide definitive answers.

The global market for these essential research tools is significant and growing, valued at approximately $65.91 billion in 2025 and projected to reach $108.74 billion by 2034 5 .
The National Academy of Sciences awards honor more than individual scientific achievements—they celebrate the collective human endeavor to understand our world and universe.
"When we invest in basic scientific research and celebrate those who excel at it, we are ultimately investing in a better future for all of humanity—on Earth, and perhaps one day, beyond."
Scientific discoveries address pressing global issues from climate change to pandemics
Medical breakthroughs extend and improve quality of life worldwide
Innovations in technology and environmental science create a more sustainable world
By recognizing scientific excellence, the NAS awards inspire students and early-career researchers to pursue their curiosity and contribute to the advancement of knowledge. These honors highlight the importance of scientific literacy and the role of research in addressing the complex challenges facing our world.
