Can artificial intelligence help find life on Mars or icy worlds?      (via sciencedaily.com) 

Researchers have mapped the sparse life hidden away in salt domes, rocks and crystals at Salar de Pajonales at the boundary of the Chilean Atacama Desert and Altiplano. Then they trained a machine learning model to recognize the patterns and rules associated with their distributions so it could learn to predict and find those same distributions in data on which it was not trained. In this case, by combining statistical ecology with AI/ML, the scientists could locate and detect biosignatures up to 87.5 percent of the time and decrease the area needed for search by up to 97 percent.

Edible electronics: How a seaweed second skin could transform health and fitness sensor tech      (via sciencedaily.com) 

Scientists have developed biodegradable algae-based hydrogels for strain sensing devices -- such as those used in health monitors worn by runners and hospital patients to track heart rate -- using natural elements like rock salt, water and seaweed, combined with graphene. As well as being more environmentally friendly than polymer-based hydrogels, commonly used in health sensor technology, the graphene algae sensors perform strongly in terms of sensitivity.

Quantum chemistry: Molecules caught tunneling      (via sciencedaily.com) 

Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in theory. The scientists provide an important reference for this fundamental effect in chemistry. It is the slowest reaction with charged particles ever observed.

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.

Wireless, soft e-skin for interactive touch communication in the virtual world      (via sciencedaily.com) 

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.

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.

Interactive cyber-physical human: Generating contact-rich whole-body motions      (via sciencedaily.com) 

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.
