Advanced artificial intelligence (AI) tools, including LLM-based conversational agents such as ChatGPT, have become increasingly widespread. These tools are now used by countless individuals worldwide for both professional and personal purposes.

Some users are now also asking AI agents to answer everyday questions, some of which could have ethical and moral nuances. Providing these agents with the ability to discern between what is generally considered ‘right’ and ‘wrong’, so that they can be programmed to only provide ethical and morally sound responses, is thus of the utmost importance.

Artificially engineered biological processes, such as perception systems, remain an elusive target for organic electronics experts due to the reliance of human senses on an adaptive network of sensory neurons, which communicate by firing in response to environmental stimuli.

A new collaboration between Northwestern University and Georgia Tech has unlocked new potential for the field by creating a novel high-performance organic electrochemical neuron (OECN) that responds within the frequency range of human neurons...

A new one-minute video game is able to accurately and efficiently identify children with autism from those who have ADHD or are neurotypical.

Developed by researchers at Kennedy Krieger Institute and Nottingham Trent University, the tool, called the Computerized Assessment of Motor Imitation (CAMI), uses motion-tracking technology to detect differences in motor imitation skills. The research is published in The British Journal of Psychiatry.

In the study, 183 children, ages 7–13, were asked to copy the dance-like movements of a video avatar for one minute, while their imitation performance was measured using ...

Researchers at the University of Colorado Anschutz Medical Campus have found a promising drug candidate that could help restore vision in individuals with multiple sclerosis (MS) and other neurological conditions that damage neurons.

The study was published this week in the journal Nature Communications.

The drug, LL-341070, enhances the brain’s ability to repair damaged myelin— the protective sheath around nerve fibers. Damage to myelin is a hallmark of diseases like MS, as well as a natural consequence of aging, often resulting in vision loss, loss of motor skills, and cognitive decline.

The research, focused on vision, demonstrated that while the brain has some ability to repair itself when myelin is damaged, the process can be slow and i...
