Scientists can now control thermal profiles at the nanoscale

Scientists have designed and tested an experimental system that uses a near-infrared laser to actively heat two gold nanorod antennae to different temperatures. The nanorods are so close together that they are both electromagnetically and thermally coupled. Yet the team measured temperature differences between the rods as high as 20 degrees Celsius and could change which nanorod was cooler and...

Despite temperature shifts, treehoppers manage to mate

During the mating season, male treehoppers—small plant feeding insects—serenade potential mates with vibrational songs sent through plant stems. If a female treehopper's interest is sparked, a male-female duet ensues until mating occurs.

Finally, a silent wireless breast pump

Elvie, a female-headed company based in the UK, designed these small and lightweight wearable smart breast pumps. Read more...More about Mashable Video, Wireless, Breast Feeding, Breastmilk, and Breast...

Making sense of remote sensing data

Remote sensor technologies like cameras, GPS trackers, and weather stations have revolutionized biological data collection in the field. Now researchers can capture continuous datasets in difficult terrain, at a scale unimaginable before these technologies became available. But as this flood of data has rolled into laboratory computers around the world, researchers have found themselves without...

Novel dual stem cell therapy improving cardiac regeneration

Researchers have recently developed a multipronged approach for concurrently rejuvenating both the muscle cells and vascular systems of the heart by utilizing two types of stem cells. The findings give hope to develop a new treatment for repairing hearts damaged by myocardial infarction, as an alternative to heart transplant.
