“#Red-light LEDs for next-generation displays” Optimizing the geometry, fabrication and electrical contacts is vital to maximizing the efficiency of the LED. Credit: Zhuag et al. Novel red LEDs are more temperature stable than those made using the conventional semiconductor of choice. In efforts to optimize the performance of light-emitting diodes (LEDs), King Abdullah University of…
“#Giant clams manipulate light to assist their symbiotic partner” The photoprotective effect enables giant calms to live in very shallow tropical waters where there is enough light for photosynthesis, but also potentially harmful UV radiation levels. Credit: Susann Rossbach Special cells in giant clams shift the wavelength of light to protect them from UV radiation…
“#We live in an age of ‘fake news,’ but Australian children are not learning enough about media literacy” Credit: www.shutterstock.com Today we release the findings from our new research into how young Australians consume and think about news media. Following a summer of bushfires and during the COVID-19 pandemic, young people have told us they…
“#Star-forming region IRAS 12272-6240 probed in infrared” Mid- and far-infrared composite colour images of the region centred on IRAS 12272-6240. Credit: Tapia et al., 2020. Astronomers have conducted spectroscopic observations of a star-forming region known as IRAS 12272-6240. Results of this observational campaign shed more light on the nature of this massive and complex region….
“#Extreme heat and rain: Thousands of weather stations show there’s now more of both, for longer” Credit: ChameleonsEye/Shutterstock A major global update based on data from more than 36,000 weather stations around the world confirms that, as the planet continues to warm, extreme weather events such as heatwaves and heavy rainfall are now more frequent,…

“#The story behind a uniquely dark wetland soil” Karen Vaughan holds a piece of soil that shows the greenish-blue, dark colors associated with the parent material. Credit: Karen Vaughan When it comes to soils, proper identification is key. Identification allows scientists to determine the story behind the soil: how it formed, how it behaves in…
“#Male fruit flies’ decline in fertility with age is not only driven by changes in sperm” Fruit fly. Credit: Shutterstock Infertility is one of the most striking effects of aging. The impact of aging on females’ fertility is more severe and much better understood, but it also affects males. Male reproductive aging is less researched,…
