Reaching like an octopus: A biology-inspired model opens the door to soft robot control      (via sciencedaily.com) 

Octopus arms coordinate nearly infinite degrees of freedom to perform complex movements such as reaching, grasping, fetching, crawling, and swimming. How these animals achieve such a wide range of activities remains a source of mystery, amazement, and inspiration. Part of the challenge comes from the intricate organization and biomechanics of the internal muscles.

The quantum twisting microscope: A new lens on quantum materials      (via sciencedaily.com) 

One of the striking aspects of the quantum world is that a particle, say, an electron, is also a wave, meaning that it exists in many places at the same time. Researchers make use of this property to develop a new type of tool -- the quantum twisting microscope (QTM) -- that can create novel quantum materials while simultaneously gazing into the most fundamental quantum nature of their electrons.

Sensing a hug from each other via the internet may be a possibility in the near future. A research team recently developed a wireless, soft e-skin that can both detect and deliver the sense of touch, and form a touch network allowing one-to-multiuser interaction. It offers great potential for enhancing the immersion of distance touch communication.

The switch made from a single molecule      (via sciencedaily.com) 

Researchers have demonstrated a switch, analogous to a transistor, made from a single molecule called fullerene. By using a carefully tuned laser pulse, the researchers are able to use fullerene to switch the path of an incoming electron in a predictable way. This switching process can be three to six orders of magnitude faster than switches in microchips, depending on the laser pulses used. Fullerene switches in a network could produce a computer beyond what is possible with electronic transistors, and they could also lead to unprecedented levels of resolution in microscopic imaging devices.

Earthquake scientists have a new tool in the race to find the next big one      (via sciencedaily.com) 

New research on friction between faults could aid in predicting the world's most powerful earthquakes. Researchers discovered that fault surfaces bond together, or heal, after an earthquake. A fault that is slow to heal is more likely to move harmlessly, while one that heals quickly is more likely to stick until it breaks in a large, damaging earthquake. Tests allowed them to calculate a slow, harmless type of tremor. The discovery alone won't allow scientists to predict when the next big one will strike but it does give researchers a valuable new way to investigate the causes and potential for a large, damaging earthquake to happen, and guide efforts to monitor large faults like Cascadia in the Pacific Northwest.

AI-Powered FRIDA robot collaborates with humans to create art      (via sciencedaily.com) 

FRIDA, a robotic arm with a paintbrush taped to it, uses artificial intelligence to collaborate with humans on works of art. Ask FRIDA to paint a picture, and it gets to work putting brush to canvas. The robot uses AI models similar to those powering tools like OpenAI's ChatGPT and DALL-E 2, which generate text or an image, respectively, in response to a prompt. FRIDA simulates how it would paint an image with brush strokes and uses machine learning to evaluate its progress as it works. FRIDA's final products are impressionistic and whimsical. The brushstrokes are bold. They lack the precision sought so often in robotic endeavors. If FRIDA makes a mistake, it riffs on it, incorporating the errant splotch of paint into the end result.

Scientists detect molten rock layer hidden under Earth's tectonic plates      (via sciencedaily.com) 

Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. The molten layer is located about 100 miles from the surface and is part of the asthenosphere, which is important for plate tectonics because it forms a relatively soft boundary that lets tectonic plates move through the mantle. The researchers found, however that the melt does not appear to notably influence the flow of mantle rocks. Instead, they say, the discovery confirms that the convection of heat and rock in the mantle are the prevailing influence on the motion of the plates.

Performing human-like motions that involve multiple contacts is challenging for robots. In this regard, a researcher has envisioned an interactive cyber-physical human (iCPH) platform with complementary humanoid (physical twin) and simulation (digital twin) elements. iCPH combines human measurement data, musculoskeletal analysis, and machine learning for data collection and augmentation. As a result, iCPH can understand, predict, and synthesize whole-body contact motions.
