‘Flapping wings’ powered by the sun (video)

(American Chemical Society) In ancient Greek mythology, Icarus’ wax wings melted when he dared to fly too close to the sun. Now, researchers reporting in ACS Applied Materials & Interfaces have made artificial wings that are actually powered by the sun. The tiny wings, which can flap even faster than those of butterflies, could someday be used in robots or devices for solar energy harvesting, the researchers say.

Scientists develop safer lead-based perovskite solar cell

(Northern Illinois University) Researchers at Northern Illinois University and the US Department of Energy’s (DOE) National Renewable Energy Laboratory are reporting today (Feb. 19) in the journal Nature on a potential breakthrough in the development of hybrid perovskite solar cells. The scientists developed a technique to sequester the lead used to make perovskite solar cells and minimize potential toxic leakage.


New world record for conversion of solar energy to electricity using quantum dots

Researchers have set a world record for the conversion of solar energy to electricity via the use of tiny nanoparticles called ‘quantum dots’. The technology has a huge range of potential applications, including the possibility to use it as a flexible, transparent skin to power cars, planes, homes and wearable technology.


Highly sensitive sensors show promise in enhancing human touch

People rely on a highly tuned sense of touch to manipulate objects, but injuries to the skin and the simple act of wearing gloves can impair this ability. Scientists report the development of a new tactile-enhancement system based on a highly sensitive sensor. The sensor has remarkable sensitivity, allowing the wearer to detect the light brush of a feather. This crack-based sensor was inspired by a spider’s slit organ.


Unexpected insights into the dynamic structure of mitochondria

As power plants and energy stores, mitochondria are essential components of almost all cells in plants, fungi and animals. Until now, it has been assumed that these functions underlie a static structure of mitochondrial membranes. Researchers have now discovered that the inner membranes of mitochondria are not static, but constantly change their structure every few seconds in living cells.


Global warming slowing down? ‘Ironic’ study finds more CO2 has slightly cooled the planet –

Climate experts have found global warming has been reduced by 0.2C to 0.25C degrees (0.36F to 0.45F) since the 1980s. The unexpected trend has been linked to carbon dioxide emissions feeding a surge in plant life growth. {%=o.title%} ]]> The…

A couple is buying land — and letting it go wild

[embedded content] Compared to the barren, brown stretch of land that juts up against it, the Singh family’s lot sticks out like a green thumb. In the video above produced by Mongabay India, you can see how the sprawling acres…
