Although digital body-temperature thermometers may be easier to read than their analog counterparts, there’s always the chance that their battery will go flat between uses. That’s where the BCool thermometer comes in, as you just give it a few shakes t… Continue reading Capacitor-packin’ BCool digital thermometer has no need for a battery
One of the challenges involved in recycling plastic is determining the specific type of plastic a given item is actually made of. To keep up with demand, large scale recycling …read more Continue reading An Open Source Detector For Identifying Plastics
Astronomers have spotted two “invisible” galaxies hiding near the dawn of the universe. The team used radio waves to peer behind a curtain of dust that was obscuring them from view, and the find suggests that there were far more galaxies in the early u… Continue reading Astronomers spot “invisible” galaxies at the dawn of the universe
