New Experiments Suggest RNA Could Have Formed Naturally, Supporting ‘RNA World’ Origin of Life Theory
Experiments show RNA, a crucial molecule for life, could form naturally on early Earth with borates stabilising ribose and aiding phosphate production. Protoplanet impacts may have delivered RNA ingredients, supporting the RNA world hypothesis and suggesting life’s building blocks could emerge efficiently on Earth and potentially Mars.

NASA New Study Challenges RNA's Role in Life’s Molecular Handedness Mystery
NASA-backed research published in Nature Communications has found that RNA molecules exhibit no chemical preference for left- or right-handed amino acids under simulated early-Earth conditions. This discovery, led by UCLA researchers, challenges the idea that RNA played a decisive role in determining the molecular handedness seen in modern life, kn...

How Rainwater Helped Stabilise Early Cells, Enabling Life's Complexity on Earth
Recent research led by Aman Agrawal, in collaboration with experts from the University of Chicago and University of Houston, uncovers the potential role rainwater played in stabilising protocells on early Earth. Their findings show how this helped prevent RNA leakage and uncontrolled mixing, allowing the formation of stable genetic material. This n...

New AI Model To Boost Patient Response To Cancer Therapy
The new tool DeepPT, developed by researchers at Australian National University (ANU), predicts a patient's messenger RNA (mRNA) profile. This mRNA -- essential for protein production -- is also the key molecular information for personalised cancer

"Exciting Idea": In A First, Scientists Recover Ribonucleic Acid From Extinct Animal
Scientists have for the first time recovered Ribonucleic acid (RNA) from an extinct species, the Tasmanian tiger, raising hope for the resurrection of animals once thought lost forever, Stockholm University researchers told AFP.

Asteroid Discovery Suggests Ingredients for Life on Earth Came From Space
Two organic compounds essential for living organisms have been found in samples retrieved from the asteroid Ryugu, buttressing the notion that some ingredients crucial for the advent of life arrived on Earth aboard rocks from space billions of years ago. Scientists said on Tuesday they detected uracil and niacin in rocks obtained by the Japanese Sp...

Researchers Identify RNA Precursors in Molecular Clouds Located in the Centre of the Milky Way
An international team of researchers have spotted traces of an organic class of molecules at the centre of the Milky Way which are precursor to molecules essential for life. It is believed that originally life was based on only RNA (ribonucleic acid) on Earth while DNA (deoxyribonucleic acid) and protein enzymes evolved later. RNA is capable of per...

New Technique for Imaging mRNA Molecules Allows Study of RNA Synthesis in Brains of Live Mice
A team of researchers, led by a University of Minnesota Twin Cities faculty member, have developed a new technique that gives scientists a window into RNA synthesis in the brain of a mouse while it is still alive. Scientists can now image mRNA molecules in the brains of living mice, as part of a technique that could be used by neurobiologists for v...
