DNA nanoswitches reveal how life’s molecules connect

‘Bio-molecular interaction analysis, a cornerstone of biomedical research, is traditionally accomplished using equipment that can cost hundreds of thousands of dollars,’ said Wyss Associate Faculty member Wesley P. Wong, Ph.D., senior author of study. ‘Rather than develop a new instrument, we’ve created a nanoscale tool made from strands of DNA that can detect and report how molecules behave, enabling biological measurements to be made by almost anyone, using only common and inexpensive laboratory reagents.’ —> Read More Here

Scientists use knowledge from the food industry to understand mass extinction

The close of the Permian Period around 250 million years ago saw Earth’s biggest extinction ever. At this time large volcanic eruptions were occurring in what is now Siberia. The volcanoes pumped out gases that led to acid rain. Falling on the supercontinent Pangaea, the acid rain killed off end-Permian forests. The demise of forests led to soil erosion and the production of organic-rich sediments in shallow marine waters. —> Read More Here
