$2 Saliva Test Could Help Detect Depression and Schizophrenia

Scientists have developed a portable biosensor that can detect levels of BDNF, a protein linked to mental health conditions such as depression, schizophrenia, and bipolar disorder. The flexible, low-cost device analyzes a drop of saliva in under three minutes, offering a fast, affordable, and noninvasive diagnostic tool.

Epigenetic Switch to Turn Memories On and Off Created

Researchers have shown for the first time that flipping an epigenetic “switch” in specific memory-holding neurons can directly alter memory strength. By targeting the gene Arc—which helps neurons adjust their connections—scientists used CRISPR-based tools to either boost or silence its activity in engram cells within the hippocampus.

Football Players Show Subtle Brain Differences Linked to CTE Risk

Brain scans of former football players revealed subtle differences in brain grooves compared to men who never played contact sports, possibly marking early signs of chronic traumatic encephalopathy (CTE). Researchers found that players had shallower grooves in a key frontal region previously associated with CTE and that years of play correlated with structural changes in another area of the brain.

When Using AI, Users Fall for the Dunning-Kruger Trap in Reverse

A new study reveals that when interacting with AI tools like ChatGPT, everyone—regardless of skill level—overestimates their performance. Researchers found that the usual Dunning-Kruger Effect disappears, and instead, AI-literate users show even greater overconfidence in their abilities.

Daily Light and Sound Therapy May Slow Alzheimer’s Decline

A long-term study found that daily 40Hz light and sound stimulation may help slow cognitive decline in people with late-onset Alzheimer’s disease. After two years of treatment, participants maintained stronger cognitive performance than typical Alzheimer’s patients and showed reduced levels of tau protein, a key disease biomarker.

Gene Editing Reverses Age-Related Memory Loss

Researchers have identified molecular mechanisms behind age-related memory decline — and shown they can be reversed. Two studies revealed that correcting specific molecular processes in the hippocampus and amygdala, and reactivating a silenced memory-supporting gene called IGF2, improved memory in older rats.

New AI Tool Reveals Genetic Link Between Memory Cells and Alzheimer’s

A new computational tool developed by researchers has uncovered genetic evidence directly linking Alzheimer’s disease to the loss of memory-making neurons, helping to resolve a decades-long mystery in dementia research. The algorithm, called seismic, matches genetic data to individual cell types, outperforming previous methods and highlighting how specific brain cells—not just immune cells—are implicated in Alzheimer’s.

Electronic Eye Implant Restores Reading Vision in AMD

A groundbreaking European trial has shown that a new electronic eye implant, paired with augmented-reality glasses, can restore reading vision to patients blinded by geographic atrophy from dry age-related macular degeneration (AMD). The device, called the PRIMA System, enabled 84% of participants to read letters, numbers, and words through previously sightless eyes.

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.
