Origin-of-life chemists propose that glyoxylate could have been the original source of sugars on the 'prebiotic' Earth Two prominent origin-of-life chemists have published a new hypothesis for how the ...
Scientists have demonstrated an alternative pathway to life-essential sugars called the glyoxylate scenario, which may push the field of pre-life chemistry past the formose reaction hurdle. For ...
Popular speculations about how life evolved out of a soup of chemicals on the early Earth often focus on the origins of DNA and RNA, the molecules of genetic information. But the genesis of genes is ...
Two simple molecules can react to form most of the intermediates in an analog of the modern-day Krebs cycle, without the need for enzymes or metals, according to a new study (Nat. Chem. 2020, DOI: ...
Enzymes catalyze the critical chemical reactions that help build and power living organisms. But chemists studying the origin of life on Earth face a vexing question: How did these metabolic reactions ...
LA JOLLA, CA— Two prominent origin-of-life chemists have published a new hypothesis for how the first sugars—which were necessary for life to evolve—arose on the early Earth. “We show that our new ...
