People Miss Racial Bias Hidden Inside AI Emotion Recognition

A new study reveals that most people fail to recognize racial bias embedded in AI systems, even when it is visible in the training data. The research shows that artificial intelligence trained on imbalanced datasets—such as happy white faces and sad Black faces—learns to associate race with emotion, perpetuating biased performance.

Astrocytes, Not Neurons, Hold the Key to Emotional Memory

New research reveals that astrocytes — not neurons — are responsible for stabilizing emotional memories by re-engaging during recall. After an emotionally intense event, such as fear, specific astrocytes become biologically tagged with adrenoreceptors, making them responsive when the memory is later reactivated.

Moving Away Makes Faces Seem Angrier

New research shows that our own physical movements can alter how we perceive emotions on others’ faces. In a virtual reality experiment, participants were more likely to judge a face as angry when they actively moved away from it, compared to when the face moved away from them.

EEG Test May Reveal Who Loses Libido on Antidepressants

A new study reveals that serotonin levels in the brain, measured using a simple EEG-based test, can predict who will experience sexual side effects from SSRI antidepressants. Researchers found that people with higher serotonin activity before treatment were significantly more likely to have difficulty reaching orgasm during antidepressant use.

Inflammatory Brain Cells Driving Progressive MS Discovered

Researchers have identified a rare type of brain cell that may drive the chronic inflammation and neurodegeneration seen in progressive multiple sclerosis (MS). These cells, called disease-associated radial glia-like (DARG) cells, appear six times more often in patients with progressive MS than in healthy individuals.

Brain-AI System Translates Thoughts Into Movement

Researchers have created a noninvasive brain-computer interface enhanced with artificial intelligence, enabling users to control a robotic arm or cursor with greater accuracy and speed. The system translates brain signals from EEG recordings into movement commands, while an AI camera interprets user intent in real time.

“Mind-Reading” Tech Decodes Inner Speech With Up to 74% Accuracy

Scientists have, for the first time, decoded inner speech—silent thoughts of words—on command using brain-computer interface technology, achieving up to 74% accuracy. By recording neural activity from participants with severe paralysis, the team found that inner speech and attempted speech share overlapping brain activity patterns, though inner speech signals are weaker.

Brain-to-Voice AI Streams Natural Speech for People with Paralysis

Researchers have developed a brain-computer interface that can synthesize natural-sounding speech from brain activity in near real time, restoring a voice to people with severe paralysis. The system decodes signals from the motor cortex and uses AI to transform them into audible speech with minimal delay—less than one second.

Breaking Silence: Giving the Silent a Voice Through Thoughts

Researchers enabled a silent person to produce speech using thought alone. Depth electrodes in the participant's brain transmitted electrical signals to a computer, which then vocalized imagined syllables. This technology offers hope for paralyzed individuals to regain speech. The study marks a significant step towards brain-computer interfaces for voluntary communication.

Biofeedback Speeds Up Speech Therapy for Struggling Kids

A large-scale clinical trial tested biofeedback-based therapy for children with residual speech sound disorder, a condition where pronunciation errors persist past age eight. Biofeedback methods—like ultrasound imaging or acoustic displays—gave children visual cues to adjust their tongue movements, accelerating progress with difficult sounds such as “r.”
