(Phys.org)—A combined team of researchers from Italy and Russia has shown that prebiotic compounds can be synthesized by irradiating liquid formamide (aka methanamide) mixed with meteorite dust. In their paper published ...
Kinetic and thermodynamic considerations reported by researchers at the Tokyo Institute of Technology suggest that thioesters at the heart of many theories on the origin of life are unlikely primordial contributors. The research ...
