Nanoscale alloy redesign tackles cold brittleness for potential deep-space and deep-sea applications‎

Metallic materials used in extremely cold environments must maintain high strength, ductility and fracture toughness to support applications in aerospace, clean energy, superconducting systems and deep-space exploration. However, traditional alloys often suffer performance degradation at ultralow temperatures because of the long-standing trade-off between strength, ductility and toughness. Although metals may become stronger at lower temperatures, they can also become more brittle and prone to fracture.

Seabird family tree predicts which species accumulate plastic better than diet, global analysis finds‎

What seabirds eat might seem like a good starting point for identifying species that tend to accumulate plastic in their digestive systems. Yet a recent global analysis suggests that mapping the evolutionary relatives of birds could offer better clues than their diets or feeding methods alone.

Ancient stalagmites reveal exceptions to Asia–South America monsoon seesaw over the past 450,000 years‎

In places like South Asia, Africa and parts of the Americas, monsoon rains supply water for drinking, crops and hydropower for billions of people. Understanding the patterns that monsoons tend to follow can help people plan for drought risks affecting agriculture, reservoirs and hydropower across distant regions.

Swinging virtual lightsabers and punching improve pattern-based learning in VR tests‎

Punching a virtual response box or swinging a virtual lightsaber can dramatically improve learning on certain tasks, according to new research from Florida Atlantic University's College of Engineering and Computer Science, which challenges long-standing assumptions about how people learn.
