Fri, 08 Aug 2008 New Biochemical Pathway That Triggers Critical Repairs In DNA Replication Process Discovered. Scientists have unraveled a new biochemical pathway that triggers a critical repair response to correct errors in the DNA replication process that could otherwise lead to harmful or fatal mutations in cells. Though the work focused on yeast cells, the team expects to find an analogous system in human cells that could be exploited as a target for potential therapies for cancers, which are often caused by such repair mechanisms going off course.more

Wed, 30 Jul 2008 Results of the 39th International Physics Olympiad "IPhO 2008" held between 20-29 July 2008 in Hanoi, Vietnam gives China and Taiwan top Gold medals. Male students from 82 participating country teams sweeped 44 Gold medals with one exception from a Romanian female student. Three teams from Arab countries; Saudi Arabia, Kuwait and Syria (as observer) have paricipated but were not classified. more

Tue, 29 Jul 2008 Bioengineers Develop "Microscope On A Chip". Researchers at the California Institute of Technology have turned science fiction into reality with their development of a super-compact high-resolution microscope, small enough to fit on a finger tip. This "microscopic microscope" operates without lenses but has the magnifying power of a top-quality optical microscope, can be used in the field to analyze blood samples for malaria or check water supplies for giardia and other pathogens, and can be mass-produced for around $10.more

Mon, 21 Jul 2008 Controlled Growth Of Truly Nanoscale Single Crystal Fullerites For Device Applications. Researchers have found a way to make ultra-small pure carbon crystals entirely formed from the spherical carbon "buckyball" molecule known as C60. The method used involves mixing two liquids together, one of which contains C60, at low temperature. more

Mon, 14 Jul 2008 Multitasking Nanotechnology: Tiny Electronically Active Chemicals Can Form Ordered Layers. Tiny electronically active chemicals can be made to form ordered layers on a surface. These nanostructured layers may one day be used to build the components of electronics devices, such as transistors and switches, for a future generation of powerful computers based on molecules rather than silicon chips.more

Thu, 10 Jul 2008 Early Warning System For Earthquakes: Seismic "Stress Meter" Warned Of Earthquake 10 Hours In Advance. Although measurement techniques surrounding earthquakes have improved enormously over the last few decades, it has remained very difficult to measure changes in the crust that could enable earthquake prediction. Now, scientists have measured interesting changes in the speed of seismic waves that preceded two small earthquakes by 10 and 2 hours. These measurements are an encouraging sign that hold promise for the field of earthquake prediction. more
