Life doesn’t wait for Earth to become “easy.” Our new study shows that ancient life used rare Earth metals (molybdenum and tungsten) 3 billion years ago, reshaping how we think about metabolism, evolution, and the search for life beyond Earth. nature.com/articles/s4146… @NASA

More than 3 billion years ago, life appears to have used molybdenum even though Earth’s oceans held only trace amounts of it—complicating the simple “tungsten first, molybdenum later” picture. @NASA @NatureComms phys.org/news/2026-05-b…

The toughest and arguably the most sacred part of being a scientist is the commitment to see the world for what it is, without the comfort of looking away.

@betulland Betul Hocam, ben o bahsettigim start up'u kurdum, Amerika hukumetinden takdir belgesi, Hong Kong'da surdurulebilirlik odulu aldik, 20 kisilik ekip kurdum, $100k fon aldik. Simdi oradan ayriliyor olsam da, iki ayri sirket daha kurdum ve artik bir CEO'yum. Guncellemek istedim. :)

Scientists just reconstructed an enzyme used by life 3.2 billion years ago, confirming a chemical fingerprint left by ancient microbes. The discovery reveals new clues about Earth’s early biosphere & gives future explorers a reliable sign to search for past life on other worlds. go.nasa.gov/49QiDRl

Check out @NASA’s new press release on how we recreated a molecule used by some of Earth’s earliest life forms, helping us understand how life began here and how we might spot signs of life on other planets! Big congrats to first author, Holly Rucker! science.nasa.gov/science-resear…

Life is not discrete. It is fluid and mobile. It will forever defy any measure, and that makes it truly worth studying.

By studying the way life once endured a frozen, unstable planet, @NASA astrobiologist @betulland is hoping to find clues for how we might face environmental challenges today—and prepare for what’s coming next.

At Breakthrough Discuss 2025, Betül Kaçar (@UWMadison & @NASA ) explored “Ancient Biological Signatures,” revealing how resurrecting Precambrian enzymes in living cells reveals Earth’s early biosignatures. Her innovative fusion of synthetic biology and ancestral reconstruction advances our understanding of life’s origins and promises new tools for detecting life beyond Earth.
