Engineering experts see how buildings and materials fared against walls of water
An inspection of Thai villages and ports struck by tsunami waves has uncovered some engineering lessons that might reduce casualties and destruction in future oceanic upheavals, a Johns Hopkins researcher said.
Robert A. Dalrymple, an internationally recognized expert on water waves and coastal engineering, was part of a nine-member team that recently toured southern Thailand, examining
A team of geologists from Duke University and the Woods Hole Oceanographic Institution has discovered a grinding, coordinated ballet of crustal “microplates” unfolding below the equatorial east Pacific Ocean within a construction zone for new seafloor.
The scientists deduced that relatively small sections of the ocean floor there, and perhaps in other similar places, may be slowly rotating like imperfectly meshing cogs in a machine. The unexpected findings provide new insights
In a few days, a three-man scientific expedition called Pole Track is to embark upon a gruelling 1000 km trek across the frozen Arctic to collect valuable data for climate-change research. Throughout the demanding two-month expedition, the team will also take thousands of snow depth measurements in support of ESAs CryoSat mission.
The international Pole Track team is led by the Dutch professional explorer Marc Cornelissen who is passionate about the polar environment and de
The retreat of Antarctic ice shelves is not new according to research published this week (24 Feb) in the journal Geology by scientists from Universities of Durham, Edinburgh and British Antarctic Survey (BAS).
A study of George VI Ice Shelf on the Antarctic Peninsula is the first to show that this currently ‘healthy’ ice shelf experienced an extensive retreat about 9500 years ago, more than anything seen in recent years. The retreat coincided with a shift in ocean currents t
Using high-intensity ultrasound, researchers at the University of Illinois at Urbana-Champaign have created hollow nanospheres and the first hollow nanocrystals. The nanospheres could be used in microelectronics, drug delivery and as catalysts for making environmentally friendly fuels.
“We use high-intensity ultrasound to generate nanoparticles of molybdenum disulfide or molybdenum oxide, which bind to the surface of tiny silica spheres that are much smaller than red blood cells
