Caltech-led team creates damage-tolerant metallic glass

PASADENA, Calif. — Glass is inherently strong, but when it cracks or otherwise fails, it proves brittle, shattering almost immediately. Steel and other metal alloys tend to be tough — they resist shattering — but are also relatively weak; they …

New glass tops steel in strength and toughness

Glass stronger and tougher than steel? A new type of damage-tolerant metallic glass, demonstrating a strength and toughness beyond that of any known material, has been developed and tested by a collaboration of researchers with the U.S. Departme…

Researchers create new high-performance fiber

Researchers at Northwestern University have nanoengineered a new kind of fiber that could be tougher than Kevlar.
Working in a multidisciplinary team that includes groups from other universities and the MER Corporation, Horacio Espinosa, James N. …

Climate change: Can geoengineering satisfy everyone?

Reflecting sunlight from the Earth by geoengineering would undoubtedly cool the climate, but would different countries agree on how much to reflect? Research by climate scientists at the University of Bristol shows that the impact of geoengineering …

Surfing for earthquakes

A better understanding of the ground beneath our feet will result from research by seismologists and Rapid — a group of computer scientists at the University of Edinburgh. The Earth’s structure controls how earthquakes travel and the damage they ca…
