Gold Nanoparticles Restore Vision in Macular Degeneration

A new study shows that gold nanoparticles injected into the retina can restore vision in mice with retinal degeneration, offering a less invasive alternative to current retinal prostheses. When activated by patterned infrared light, these nanoparticles stimulate retinal cells, bypassing damaged photoreceptors.

This shows people surrounded by screens.

Brain Learns to Tune Out Distractions with Repeated Exposure

Our brains can adapt to filter out repeated distractions, according to a new EEG study. Participants learned to ignore frequent visual distractions, such as a red shape in the same location, while searching for a target.

Breathing Syncs with Pupil Size, Revealing a New Mind-Body Link

A groundbreaking study has revealed that our pupils change size in sync with our breathing—a response now dubbed the "pupillary respiratory phase response." Researchers confirmed that pupils are smallest around the start of inhalation and largest during exhalation, regardless of lighting, focus, or cognitive effort.

Vivid Visual Memory May Raise PTSD Risk

A new study shows that having a vivid imagination—especially for visual details—may increase a person’s risk of developing posttraumatic stress disorder (PTSD) after trauma. In contrast, strong spatial memory skills, such as understanding where objects are located in space, may protect against PTSD symptoms, particularly in men.

Eye Clues May Reveal Early Dementia Risk

A new study has found that blood vessels in the retina may hold early clues about a person’s risk of developing dementia. Researchers observed that narrower arterioles, wider venules, and thinner retinal nerve fiber layers were linked to higher dementia risk around midlife.

Every Breath You Take Alters Your Visual Perception

Researchers have discovered that breathing affects pupil size, with the pupil being smallest during inhalation and largest during exhalation. This newly identified mechanism is independent of external stimuli and could influence vision by alternating between detail enhancement and object detection.

Study Links Schizophrenia to Visual Contrast Sensitivity Deficits

People with schizophrenia experience impaired contrast perception, affecting their ability to differentiate light intensity and recognize shapes and textures. This deficit may stem from disruptions in glutamate neurotransmission, a key neural mechanism in the disease.

How the Brain Processes Space and Time

New research highlights a functional hierarchy in the brain's processing of space and time. In posterior areas, like the occipital cortex, space and time are tightly linked and processed by the same neurons. In anterior regions, such as the frontal cortex, space and time are processed independently, with distinct neural populations forming "time maps" for specific durations.

Multifocal Lenses Reduce Myopia Risks

New research demonstrates that high-add multifocal contact lenses significantly slow myopia progression in children, with benefits that persist even after discontinuation. The lenses, designed to slow eye growth and reduce long-term myopia-related risks, showed no rebound effect after treatment stopped.

This shows the outline of a head and a brain.

Brain Merges Sight and Sound to Understand Speech in Noisy Settings

Researchers are investigating how the brain combines visual and auditory cues to improve speech comprehension in noisy environments. The study focuses on how visual information, like lip movements, enhances the brain's ability to differentiate similar sounds, such as "F" and "S."

Pupil Dynamics During Sleep Reveal Brain’s Memory-Saving Secrets

Researchers have discovered that pupil size during non-REM sleep correlates with memory consolidation. When pupils contract, the brain focuses on consolidating new memories; when dilated, it processes older ones.

Ancient Brain Reflex Develops Without Sensory Input

Researchers uncovered that the vestibulo-ocular reflex, a vital brain circuit stabilizing gaze during body tilts, matures independently of sensory input in newborns. This reflex, essential for perceiving a stable environment, enables the eyes to counter-rotate with body movements.
