Alternative technique for determining the true activity of catalysts: Researchers from Japan perform reliable estimation of the activity of water-splitting catalysts with an unconventional technique
Electrolysis of water or “water electrosplitting” has received a great deal of attention recently owing to its potential as a clean source of hydrogen, the oft-touted fuel of the future. However, two issues have long stood in the way: the large amount of energy lost, and the cost of electrocatalysts (catalysts used for electrolysis). Fortunately, […]
Bringing the sun into the lab: Liquid-metal experiment provides insight into the heating mechanism of the sun’s corona
Why the Sun’s corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A “hot” trail to explain this effect leads to a region of the solar atmosphere just below the corona, where sound waves and certain plasma waves travel at the same speed. In an experiment using […]
Researchers shrink camera to the size of a salt grain
Micro-sized cameras have great potential to spot problems in the human body and enable sensing for super-small robots, but past approaches captured fuzzy, distorted images with limited fields of view. Now, researchers at Princeton University and the University of Washington have overcome these obstacles with an ultracompact camera the size of a coarse grain of […]
Too Much Sitting May Be Bad for Your Mental Health
Latest Mental Health News THURSDAY, Nov. 11, 2021 (HealthDay News) Call it the great pandemic sit-down. As COVID-19 turned daily commutes into shuffles between rooms at home, and Netflix replaced time spent at the gym or playing sports, Americans have been sitting a lot more. Now a new study suggests it may be […]
Enabling the ‘imagination’ of artificial intelligence
Imagine an orange cat. Now, imagine the same cat, but with coal-black fur. Now, imagine the cat strutting along the Great Wall of China. Doing this, a quick series of neuron activations in your brain will come up with variations of the picture presented, based on your previous knowledge of the world. In other words, […]
