Tracing the origin of life—a new abiotic pathway for the formation of peptide chains from amino acids
A team of scientists from France and Austria has discovered a new abiotic pathway for the formation of peptide chains from amino acids—a key chemical step in the origin of life. The current study provides strong evidence that this crucial step for.....»»
Biologists discover how plants evolved multiple ways to override genetic instructions
Biologists at Washington University in St. Louis have discovered the origin of a curious duplication that gives plants multiple ways to override instructions that are coded into their DNA. This research could help scientists exploit a plant's existin.....»»
The high cost of complexity: New study explores energy needs of multicellular life
Between 1.8 billion and 800 million years ago, earthly life was in the doldrums. During this period, called the "boring billion," the complexity of life remained minimal, dominated by single-celled organisms with only sporadic ventures into multicell.....»»
Vampire bats" metabolism mirrors that of blood-sucking insects, biologists find
A pair of biologists at the University of Toronto has found that vampire bats are able to burn amino acids as a fuel source similarly to blood-sucking insects. In their study published in the journal Biology Letters, Giulia Rossi and Kenneth Welch co.....»»
Gamma radiation converts methane into complex organic molecules and could explain the origin of life
Gamma radiation can convert methane into a wide variety of products at room temperature, including hydrocarbons, oxygen-containing molecules, and amino acids, according to a new article published in the journal Angewandte Chemie International Edition.....»»

Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
Decadal climate patterns reveal new insights into tropical cyclone formation and El Niño-Southern Oscillation link
A new study has revealed how decadal-scale climate fluctuations impact the ability of climate models to simulate tropical cyclone frequency in response to El Niño-Southern Oscillation (ENSO) events. This finding offers an improved understanding of t.....»»
