Epicurus's Ancient Cure: Why Freedom From Fear Matters More Than Pleasure
An editorial exploration of Epicurus's philosophy reveals his actual teaching was about freedom from pain and fear, not hedonism, with fear of death as the root cause of anxiety.
Astronomers Rethink Universal Mass Measurement as Star Formation Assumptions Crumble
Astronomers are reconsidering the initial mass function (IMF), a decades-old mathematical tool for estimating galaxy masses. University of Missouri researchers found that star formation ratios vary by environment, suggesting the IMF needs environment-specific adjustments rather than universal application.
Plastic welds show molecular 'memory' that strengthens pipe joints
Research reveals plastic welds maintain molecular memory of original surfaces, enhancing strength in pipe joints and potentially improving industrial applications.
Scientists unlock the molecular 'memory' that makes plastic pipe welds stronger
Columbia University researchers discovered that plastic welds retain molecular memory of original surfaces, creating stronger joints through enhanced crystallization. The finding could improve welding reliability and support recycled plastic use in critical infrastructure.
