Para peneliti telah mengidentifikasi tanda statistik dalam molekul organik yang membedakan kimia biologis dari nonbiologis, yang menawarkan perangkat baru untuk mendeteksi kehidupan di luar bumi. Pendekatan ini menganalisis distribusi asam amino dan asam lemak tanpa memerlukan instrumen khusus. Metode ini dapat diterapkan pada data dari misi luar angkasa yang sedang berlangsung maupun di masa depan.

Sebuah studi yang diterbitkan dalam Nature Astronomy menunjukkan bahwa sistem kehidupan menghasilkan pola organisasi yang berbeda pada molekul tertentu. Asam amino dari sumber biologis cenderung lebih bervariasi dan terdistribusi secara merata, sementara asam lemak dari proses tak hidup menunjukkan keseragaman yang lebih besar. Para ilmuwan mengadaptasi metode statistik dari ekologi untuk mengukur kekayaan dan kesetaraan dalam senyawa-senyawa ini di hampir 100 kumpulan data dari mikroba, meteorit, fosil, dan sampel laboratorium.

New method uses amino acid reactivity to detect alien life

Scientists have developed a test based on the reactivity of amino acids that could identify alien life differing from Earth-based organisms. The approach analyzes molecular energy differences to distinguish living from non-living samples with high accuracy. This tool may aid future missions to Mars or Saturn's moons.

Scientists propose detecting alien life via planetary patterns

A team of researchers has introduced a new method to detect extraterrestrial life by identifying statistical patterns across multiple planets rather than focusing on individual worlds. Led by Harrison B. Smith and Lana Sinapayen, the approach relies on life's potential to spread between planets and alter their environments. This 'agnostic biosignature' could help prioritize observations amid limited telescope time.

UC Berkeley scientists discover microbe with ambiguous genetic code

Sabtu, 28 Februari 2026 Dilaporkan oleh AI

Researchers at the University of California, Berkeley have identified a methane-producing archaeon that interprets a standard stop codon in two ways, challenging a core principle of biology. The microbe, Methanosarcina acetivorans, sometimes adds an amino acid called pyrrolysine instead of halting protein synthesis. This flexibility may aid in metabolizing compounds linked to human health.
