High Precision Mapping from Scratch
The fun of owning rural property is that knowing where your land actually starts and ends is a guess usually. Sure, you have a parcel description, and maybe even an online service with “official” GIS boundaries (for us here in New Brunswick, this is GeoNB ). However, since it’s in the middle of the forest, the odds of…

Light-induced whole-molecule vibration can rupture melanoma cells’ membrane
Rice scientists and collaborators at Texas A&M University and University of Texas MD Anderson Cancer Center have found a new way to kill cancer cells by using near-infrared light to make a small dye molecule attached to their membrane vibrate strongly. It is the first time this kind of mechanical molecular action has…
