different-phases-of-evolution-during-ice-age

Cold-adapted animals started to evolve 2.6 million years ago when the permanent ice at the poles became more prevalent. There followed a time when the continental ice sheets expanded and contracted and around 700,000 years ago the cold periods doubled in length. This is when many of the current cold-adaptedContinue Reading

modulation-of-antiviral-response-in-fungi-via-rna-editing

The molecular pathways involved in antiviral defenses and counter-defenses in host-pathogen systems remain unclear. Researchers have used Neurospora crassa as a model organism to explore how RNA editing influences fungal antiviral responses. They identified two neighboring genes — an RNA-editing enzyme (old) and a transcription factor (zao) — that regulateContinue Reading
