upstart writes:Illuminating Origami Is Just Around The Corner:Pop-up greeting cards are about to get a whole lot more interesting. Researchers at Seoul National University in Korea have created glowing 3D objects with a series of prototypes that fold thin QLED (Quantum Dot LED) sheets like origami. They used a CO laser to etch "fold lines" in the QLED so the sheets could be formed into 3D shapes. The bends are actually rounded, but at 5μm they appear to be sharp corners and the panels continue to illuminate across the fold lines for at least 500 folds. Some glow in solid colors, while others use smaller addressable areas to create animated matrix displays of patterns and letterforms. See the short video after the break, read the Physics World article or to see all the prototypes and dig into details of the full research paper in Nature (freed from the paywall by SharedIt).51-second YouTube video.Original SubmissionRead more of this story at SoylentNews.

When fields are laying fallow, it is very important to remove the weeds that are trying to establish themselves. When the density of the weeds is low, it is not efficient to spray the whole field with herbicide, so proprietary sensor-based spray booms are used to identify and spray herbicide directly onto the weeds. Researchers from the University of Sydney have developed an open-source, low-cost and image-based device for weed detection in an effort to give this technology wider availability. The demonstration system uses a Raspberry Pi 4 with a Raspberry Pi HQ Camera and 6-mm focal length lens. The Python code and detailed instructions reside in the OWL github repository.

hubie writes:Some dynamic systems can develop multi-periodicity, meaning that some parameter, such as a mechanical oscillation, can switch between different vibrational frequencies or amplitudes. For instance, a small-scale disturbance is coupled into a large-scale one.This has been observed in muscle motion, laser stability, seismic motion, etc, and there is much to understand about these couplings in chaotic systems. Initiated by an apparent diversion from pandemic boredom, Promode Bandyopadhya noticed that when shucked cobs of corn were placed on a glasstop hotplate, the cob oscillates autonomously about three axes with varying amplitudes and frequencies that shifted randomly with time. He videoed ears of corn as well as a number of other smooth fruits on a hot surface and extracted their motion over time. His results are summarized in a tour de force of mechanical dynamics in a Nature Scientific Reports paper. He observed that corn cobs roll, pitch, and yaw, but green chilies, blueberries, tropical berries, red grapes, oblong grapes and grape tomatoes only roll and yaw.
