Blue PHOLEDs: Final color of efficient OLEDs finally viable in lighting      (via sciencedaily.com)     Original source 

Lights could soon use the full color suite of perfectly efficient organic light-emitting diodes, or OLEDs, that last tens of thousands of hours. The new phosphorescent OLEDs, commonly referred to as PHOLEDs, can maintain 90% of the blue light intensity for 10-14 times longer than other designs that emit similar deep blue colors. That kind of lifespan could finally make blue PHOLEDs hardy enough to be commercially viable in lights that meet the Department of Energy's 50,000-hour lifetime target. Without a stable blue PHOLED, OLED lights need to use less-efficient technology to create white light.

New brain-like transistor mimics human intelligence      (via sciencedaily.com)     Original source 

Researchers develop transistor that simultaneously processes and stores information like the human brain. Transistor goes beyond categorization tasks to perform associative learning. Transistor identified similar patterns, even when given imperfect input. Previous similar devices could only operate at cryogenic temperatures; new transistor operates at room temperature, making it more practical.

Meet 'Coscientist,' your AI lab partner      (via sciencedaily.com)     Original source 

An artificial intelligence-driven system has autonomously learned about certain Nobel Prize-winning chemical reactions and designed a successful laboratory procedure to make them. The AI did so in just a few minutes and correctly on its first attempt. According to the authors, this is the first time that a non-organic intelligence planned, designed and executed this complex reaction that was invented by humans.

15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems      (via sciencedaily.com)     Original source 

Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.

Interactive screen use reduces sleep time in kids      (via sciencedaily.com)     Original source 

While screen time is generally known to affect sleep, new research suggests that interactive engagement, such as texting friends or playing video games, delays and reduces the time spent asleep to a greater extent than passive screen time, like watching television -- especially for teens.

Saving endangered species: New AI method counts manatee clusters in real time      (via sciencedaily.com)     Original source 

Accurately counting manatee aggregations within a region is crucial yet challenging. Harnessing the power of AI, researchers are using a deep learning-based crowd counting approach to automatically count the number of manatees in a designated region, using images captured from CCTV cameras, which are readily available, as input. The pioneering study not only addresses the technical challenges of counting in complex outdoor environments but also offers potential ways to aid endangered species.

Whale-SETI: Groundbreaking encounter with humpback whales reveals potential for nonhuman intelligence communication      (via sciencedaily.com)     Original source 

A team of scientists had a close encounter with a non-human (aquatic) intelligence. The Whale-SETI team has been studying humpback whale communication systems in an effort to develop intelligence filters for the search for extraterrestrial intelligence. In response to a recorded humpback 'contact' call played into the sea via an underwater speaker, a humpback whale named Twain approached and circled the team's boat, while responding in a conversational style to the whale 'greeting signal.' During the 20-minute exchange, Twain responded to each playback call and matched the interval variations between each signal.
