Eye Protein Levels Linked to Cognitive Decline

A new study reveals that levels of the SLIT2 protein in eye and blood samples are linked to cognitive performance in middle-aged adults. Researchers found that lower SLIT2 in vitreous humor correlated with poorer memory and global cognition, while higher SLIT2 in plasma also predicted lower cognitive scores.

Cooler Nights and Brighter Days Boost Sleep in Dementia Patients

A large-scale study shows that indoor environmental changes—such as cooler bedroom temperatures at night and brighter indoor light during the day—can significantly improve sleep in people living with dementia. Researchers analyzed over 26,000 days of data using contactless sensors placed in participants’ homes.

Brain Iron Levels Predict Cognitive Decline Risk

A new study demonstrates that brain iron levels, measured with a special MRI technique, can predict cognitive decline years before symptoms of Alzheimer’s disease appear. Researchers followed 158 cognitively healthy older adults and found that higher iron levels in memory-related regions of the brain were associated with a greater risk of mild cognitive impairment.

Evolution of Human Brain May Explain High Autism Rates

A new study suggests that autism may be linked to the rapid evolution of brain cell types unique to humans. Researchers found that outer-layer neurons in the human brain evolved far more quickly than in other apes, with significant changes in autism-associated genes.

Left or Right? Brain’s Split Determines How We Map Numbers

A study in newborn chicks shows that brain lateralisation is essential for the development of a left-to-right mental number line. Chicks with strongly lateralised brains consistently mapped numbers from left to right, while weakly lateralised chicks did not display this pattern.

Loneliness Drives Teens to Seek Rewards

A new study reveals that adolescents are highly sensitive to even brief periods of social isolation, showing a sharp increase in motivation to seek rewards after just a few hours alone. This heightened drive can encourage reconnection but may also lead to risky behaviors if social contact isn’t available.

AI Matches Human Social Perception

Researchers found that ChatGPT could assess social interactions in videos and images almost as accurately as humans. The AI’s evaluations of social features like cooperation, hostility, and body movements were even more consistent than those of a single person.

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.”

REM Sleep Reactivation Locks Memories in Place

Rare adult-born neurons in the hippocampus are reactivated during REM sleep, locking waking experiences into long-term memory. Using genetically modified mice, they found that these neurons fire in the same patterns during sleep as they did during learning.

Chemotherapy Drug Found to Disrupt Circadian Clock

Nearly half of cancer patients suffer circadian rhythm disruptions during chemotherapy, worsening side effects. A new study using mice shows that paclitaxel, a common breast cancer drug, may disturb the brain’s master clock without directly entering it.

Hidden DNA Loops Linked to Early Spread of Brain Cancer

Scientists have discovered that rogue DNA rings, called extrachromosomal DNA (ecDNA), appear early in glioblastoma and drive its rapid growth and resistance to therapy. By combining patient data, imaging, and computational modeling, researchers found that ecDNA often carries the EGFR cancer gene and its aggressive variants.

Wireless Implant Delivers Drugs Deep in Brain

Researchers have developed a wireless, implantable neural interface that can deliver drugs directly to deep brain regions with precision. The device uses a soft, flexible micro-pump and channel design to ensure controlled, backflow-free infusion without external equipment.
