Doors to ‘World’s Quietest Room’ open
London, September 8 (ANI): Doors of the ‘quietist room in the world’ have been thrown open to allow scientists to study nanotechnology in Bristol, UK.
The architecture of the 11-million pound laboratory, that virtually has no [...]
Quake experts develop new system to monitor underground movements
London, Aug 31 (ANI): A five-strong group of scientists have developed a new technique that can monitor movements beneath the earth’s surface to help understand how earthquakes behave.
The scientists, led by Andrew Curtis, Professor of Mathematical Geoscience at Edinburgh University, used computers to simulate the motion of one earthquake at the location of another to [...]
Now, acoustic tweezers to position tiny objects
Washington, Aug 29 (ANI): While it gets quite difficult to manipulate tiny objects like single cells or nanosized beads via relatively large, unwieldy equipment, Penn State engineers have now designed a new system that uses sound as a pair of tiny tweezers that are small enough to place infinitesimal objects on a chip.
While optical tweezers [...]
Soon, soundwaves may help find early dental decay
Washington, Aug 25 (ANI): Aussie researchers are developing a tool that can use sound waves to identify early stages of tooth decay by measuring the mineral content of teeth.
Tooth decay begins by acid-forming bacteria eating away at the enamel, causing minerals to leach from it, softening, and weakening the tooth.
Sometimes dentists can identify this demineralisation [...]
