Researchers demonstrate the possibility of using ultrastable film formation to improve the performance of state-of-the-art OLEDs. The researchers show in a detailed study significant increases of efficiency and operational stability (>15% for both parameters and all cases, significantly higher for individual samples) are achieved for 4 differentultrastable glasses,.
Organic light-emitting diodes (OLEDs) truly have matured enough to allow for first commercial products in form of small and large displays. In order to compete in further markets and even open new possibilities (automotive lighting, head-mounted-displays, micro displays, etc...

How would we do it? By using viruses as tiny aestheticians. A new discovery about the effects of aging in our cells could allow doctors to cure or prevent diabetes, fatty liver disease and other metabolic diseases – and possibly even turn back the clock on aging itself. The new finding from the University of Virginia School of Medicine suggests that fatty liver disease and other unwanted effects of aging may be the result of our cells’ nuclei getting wrinkly...

New biotech could reduce time and cost of developing medicine for deadly lung disease. The innovation, lung-on-a-chip technology, relies on the same technology used to print electronic chips, photolithography. Only instead of semiconducting materials, researchers placed upon the chip arrays of thin, pliable lab-grown lung tissues – in other words, its lung-on-a-chip technology.

“Obviously it’s not an entire lung, but the technology can mimic the damaging effects of lung fibrosis...

Pre-cue Spindles Prevented Post-cue Spindle Increases and Negatively Predicted Memory Retention

Sleep spindles may help memory storage keep memories separate. Leading theories propose that sleep presents an opportune time for important, new memories to become stabilized. And it’s long been known which brain waves are produced during sleep. But in a new study, researchers set out to better understand the brain mechanisms that secure memory storage.

The team from Northwestern and Princeton universities set out to find more direct and precisely timed evidence for the involvement of one particular sleep wave – known as the “sleep spindle.” In the study, sleep spindles, described as bursts of brain activity typically lasting around one second, were linked to memory reactivation...
