POSTECH Develops World’s First Pixel-Based Local Sound OLED with Multi-Speaker Functionality on a Real Working 13-Inch Tablet sized OLED Display.

Analysis has shown a boulder weighing almost 1,200 tonnes in Tonga is one of the largest known wave-transported rocks in the world, providing new insights into the Pacific region’s history and risk of tsunamis.

In the intriguing realm of star-forming galaxies, the key factor isn't the total amount of gas but rather its strategic distribution within the galaxy.

A metamaterial is a composite material that exhibits unique properties due to its structure, and now researchers have used one featuring a small sawtooth pattern on its surface to move and position objects underwater without touching them directly. Adjacent speakers exert different forces on the material based on how the sound waves reflect off it, and by carefully targeting the floating or submerged metamaterial with precise sound waves, researchers can push and rotate the object attached to it.

Proteins are among the most studied molecules in biology, yet new research from the University of Göttingen shows they can still hold surprising secrets. Researchers have discovered previously undetected chemical bonds within archived protein structures, revealing an unexpected complexity in protein chemistry. These newly identified nitrogen-oxygen-sulphur (NOS) linkages broaden our understanding of how proteins respond to oxidative stress, a condition where harmful oxygen-based molecules build up and can damage proteins, DNA, and other essential parts of the cell. The new findings were published in Communications Chemistry.

Purdue University researchers have developed a metamaterial comprising of carefully arranged plates that trap air within and act as guides for the sound. With their metamaterial in place, sound from monopile installation can be reduced by 40 decibels, an improvement over the 25-decibel reduction of other methods. The material is modular and foldable, making its transport and deployment easy and inexpensive. Junfei Li will present on the work at the 188th ASA Meeting.
