New Studies of Ancient Concrete Could Teach Us to Do as the Romans Did
Berkeley Lab, UC Berkeley experiments show how natural chemistry strengthened ancient concrete
A new look inside 2,000-year-old concrete – made from volcanic ash, lime (the product of baked limestone), and seawater – has provided new clues to the evolving chemistry and mineral cements that allow ancient harbor structures to withstand the test of time. The research has also inspired a hunt for the original recipe so that modern concrete manufacturers can do as the Romans did. (more…)

Virtuelle Welten erlauben neue experimentelle Designs für die Untersuchung von Hirnfunktionen
Verhaltensexperimente sind nützliche Werkzeuge um Gehirnfunktionen zu untersuchen. Standardversuche zur Erforschung des Verhaltens von beliebten Labortieren wie Fischen, Fliegen oder Mäusen imitieren aber nur unvollständig die natürlichen Bedingungen. Das Verständnis von Verhalten und Hirnfunktion ist daher begrenzt. (more…)

Could “cocktail geoengineering” save the climate?
Washington, DC— Geoengineering is a catch-all term that refers to various theoretical ideas for altering Earth’s energy balance to combat climate change. New research from an international team of atmospheric scientists published by Geophysical Research Letters investigates for the first time the possibility of using a “cocktail” of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse gases.
