Once-endangered Kirtland’s warblers show extensive signs of inbreeding in genome

The genome of a once-endangered songbird shows extensive signs of inbreeding, according to a new study by Penn State researchers. Because inbreeding can negatively impact survival and reproduction, the results could guide continuing conservation efforts for Kirtland’s warblers, whose populations still rely on extensive management. The new study, published Dec. 9 in the journalEvolutionary Applications, […]

Scientists recreate life’s first step: Linking amino acids to RNA

Chemists at UCL have shown how two of biology’s most fundamental ingredients, RNA (ribonucleic acid) and amino acids, could have spontaneously joined together at the origin of life four billion years ago. Amino acids are the building blocks of proteins, the “workhorses” of life essential to nearly every living process. But proteins cannot replicate or […]
