What gave the first molecules their stability?      (via sciencedaily.com)     Original source 

The origins of life remain a major mystery. How were complex molecules able to form and remain intact for prolonged periods without disintegrating? A team has demonstrated a mechanism that could have enabled the first RNA molecules to stabilize in the primordial soup. When two RNA strands combine, their stability and lifespan increase significantly.

Stacked up against the rest      (via sciencedaily.com)     Original source 

Scientists have hypothesized that moir excitons -- electron-hole pairs confined in moir interference fringes which overlap with slightly offset patterns -- may function as qubits in next-generation nano-semiconductors. However, due to diffraction limits, it has not been possible to focus light enough in measurements, causing optical interference from many moir excitons. To solve this, researchers have developed a new method of reducing these moir excitons to measure the quantum coherence time and realize quantum functionality.

Talking about regeneration      (via sciencedaily.com)     Original source 

Researchers transferred genes from simple organisms capable of regenerating their bodies into common fruit flies, more complex animals that cannot. They found the transferred gene suppressed an age-related intestinal issue in the flies. Their results suggest studying genes specific to animals with high regenerative capability may uncover new mechanisms for rejuvenating stem cell function and extending the healthy lifespan of unrelated organisms.
