A Multi-Function Mimicking Neuron Moves Robots Closer to Human-Like Abilities

Artificial Intelligence, Computer & Electronics, Tech / Jorge Paka

Scientists have developed an artificial neuron that can imitate multiple brain regions, bringing us closer to robots that perceive and react to their surroundings much like humans. The Power and Limits of Neuromorphic Neurons Artificial neurons—small electronic circuits that mimic how brain cells interact—are central to neuromorphic computing, which seeks to give machines human-like intelligence. […]

A Microrobot Moves Through the Bloodstream to Deliver Medication Precisely

Biotechnology, Medicine / Evelina Jeremias

An ETH Zurich grain-sized microrobot has demonstrated in preclinical tests the ability to navigate the bloodstream, deliver drugs precisely, and dissolve, showing promise for stroke and localized cancer treatments. The system consists of a miniature capsule that holds the drug along with iron oxide nanoparticles. Iron oxide nanoparticles let operators steer the microrobot via magnetic

Scientists Create a Spacesuit with Artificial Muscles to Reduce Astronaut Strain

Aerospace, Space & Environment / Jorge Paka

A new textile-based exoskeleton from the University of Bristol could transform mobility in space and support people with disabilities on Earth. Scientists in England developed a prototype exosuit with artificial muscles to ease astronaut movement and reduce fatigue in low-gravity environments like the Moon or Mars. Innovation Driven by VIVO Hub’s Interdisciplinary Research VIVO Hub,

New Reactor Recycles Battery Waste into Lithium Feedstock

Engineering, Material & Energy, Material Technology / Eduardo Paulo

As electric vehicle use rises worldwide, discarded battery packs are rapidly turning into a significant waste source. Lithium is expensive to extract, and most existing recycling techniques consume substantial energy and chemicals, typically yielding lithium carbonate that still requires additional processing to become reusable lithium hydroxide. Instead of smelting or leaching shredded battery material (“black

Researchers Find a way to Stop Pig-Organ Transplant Rejection

Medicine, Surgerical Tech / Ngoma Manuel

Scientists have managed to prevent the rejection of a pig kidney transplanted into a human donor. The organ continued to function for 61 days in a 57-year-old brain-dead man in the United States — the longest a genetically engineered pig organ has ever lasted in a brain-dead human. In two studies published today in Nature,

IQ May Affect How Well You Understand Speech

Healthcare, Mental / Ngoma Manuel

Sometimes scientific findings reveal connections that seem surprising at first but become more understandable on closer consideration—such as a correlation between lower IQ and difficulty following conversations in noisy settings. Previous research has shown that neurodiverse individuals may struggle more than others to hear speech in noisy environments. To explore this further, a team of

Self-Adapting LLMs Resemble Students Acquiring New Knowledge

Artificial Intelligence, Tech / Eduardo Paulo

In an MIT classroom, a professor delivers a lecture as students take careful notes to review and absorb essential material in preparation for an exam. Humans naturally learn and retain new information, but large language models (LLMs) lack this ability. Once deployed, a trained LLM has a fixed “brain” that can’t permanently incorporate new knowledge.

Scientists Create a Synthetic Leaf that Turns Pollution into Energy

Material & Energy, Renewable Energy / Marcílio Santos

Modeled on natural processes, the artificial leaf harnesses sunlight and catalysts to transform CO₂ and water into energy-rich compounds like hydrogen or methanol, using advanced materials for greater efficiency than plants. This artificial photosynthesis process can both remove pollutants and produce usable energy, making it a highly discussed breakthrough in environmental science. Optimizing Materials for
