A survey of adults found most had low trust in their health care system to use artificial intelligence responsibly or to make sure an AI tool would not harm them.

The Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and NTT Research, Inc., a division of NTT, announced the publication of research showing an application of machine-learning directed optimization (ML-DO) that efficiently searches for high-performance design configurations in the context of biohybrid robots. Applying a machine learning approach, the researchers created mini biohybrid rays made of cardiomyocytes (heart muscle cells) and rubber with a wingspan of about 10 mm that are approximately two times more efficient at swimming than those recently developed under a conventional biomimetic approach.

A research team has developed two new autonomous navigation systems for cyborg insects to better navigate unknown, complex environments. The algorithms utilized only simple circuits that leveraged natural insect behaviors, like wall-following and climbing, to navigate challenging terrain, such as sandy, rock-strewn surfaces. For all difficulties of terrain tested, the cyborg insects were able to reach their target destination, demonstrating the potential of cyborg insects for surveillance, disaster-site exploration, and more.

Is it possible to tile a surface with a single shape in such a way that the pattern never repeats itself? In 2022, a mathematical solution to this 'Einstein problem' was discovered for the first time. Researchers have now also found a chemical solution: a molecule that arranges itself into complex, non-repeating patterns on a surface. The resulting aperiodic layer could even exhibit novel physical properties.

Biological motors, which aid microorganism movement in fluids, are composed of two components -- the rotor and stators. Despite much research, the exact molecular mechanism underlying stator function is yet unclear. In a new study, researchers analyzed the flagellar motor in Vibrio alginolyticus using cryo-electron microscopy and described how sodium ion flow through stators underlies stator function. Understanding biological motors better could lead to the development of efficient microscopic machines.

From predicting potholes to designing more durable concrete, artificial intelligence is paving the way for smarter infrastructure, new studies show.

Researchers are designing a global real-time monitoring system to help save the world's coral reefs from further decline, primarily due to bleaching caused by global warming.

A biohybrid hand which can move objects and do a scissor gesture has been created. The researchers used thin strings of lab-grown muscle tissue bundled into sushilike rolls to give the fingers enough strength to contract. These multiple muscle tissue actuators (MuMuTAs), created by the researchers, are a major development towards building larger biohybrid limbs. While currently limited to the lab environment, MuMuTAs have the potential to advance future biohybrid prosthetics, aid drug testing on muscle tissue and broaden the potential of biohybrid robotics to mimic real-life forms.

Researchers have achieved a breakthrough in wearable health technology by developing a novel self-healing electronic skin (E-Skin) that repairs itself in seconds after damage. This could potentially transform the landscape of personal health monitoring.

Scientists have used holographic projections to bring unprecedented resolution to a light-based 3D printing technique. The method allows the fabrication of millimeter-scale objects within seconds using significantly less energy than previous approaches.

A team of researchers succeeded in adapting an AI system to reliably assist with making nanoparticle measurements which speeds up the research process significantly.

A groundbreaking study has uncovered how specific genetic mutations influence cancer treatment outcomes -- insights that could help doctors tailor treatments more effectively. The largest study of its kind, the research analyzed data for more than 78,000 cancer patients across 20 cancer types. Patients received immunotherapies, chemotherapies and targeted therapies.

Scientists have developed new light-sensitive chemicals that can radically improve the treatment of aggressive cancers with minimal side effects. In mouse tests, the new therapy completely eradicated metastatic breast cancer tumors.

The future of manufacturing is not just about machines and AI; it's about re-empowering humans, according to a new study.

Qubits -- the fundamental units of quantum information -- drive entire tech sectors. Among them, superconducting qubits could be instrumental in building a large-scale quantum computer, but they rely on electrical signals and are difficult to scale. In a breakthrough, a team of physicists has achieved a fully optical readout of superconducting qubits, pushing the technology beyond its current limitations.

Researchers have developed an artificial intelligence (AI) tool that will help predict endangered whale habitat, guiding ships along the Atlantic coast to avoid them. The tool is designed to prevent deadly accidents and inform conservation strategies and responsible ocean development.

Researchers have developed a new AI algorithm, called Torque Clustering, that significantly improves how AI systems independently learn and uncover patterns in data, without human guidance.

Researchers have developed a method that leverages artificial intelligence to ensure accurate heart scans without added radiation or cost.

Entanglement -- linking distant particles or groups of particles so that one cannot be described without the other -- is at the core of the quantum revolution changing the face of modern technology. While entanglement has been demonstrated in very small particles, new research is thinking big, demonstrating high-fidelity entanglement between two acoustic wave resonators.

A study showed that chatbots alone outperformed doctors when making nuanced clinical decisions, but when supported by artificial intelligence, doctors performed as well as the chatbots.
