Alzheimer’s Disrupts Brain’s Internal Clock, Unraveling Gene Rhythms

Alzheimer’s disease not only damages memory but also distorts the brain’s internal clock, disrupting the daily rhythms of hundreds of genes tied to brain health. Researchers found that in mice with amyloid buildup, normal circadian gene activity in microglia and astrocytes—the brain’s immune and support cells—became erratic.

This shows the outline of a head and a clock.

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.

Breast Milk Has a Built-In Body Clock for Babies

Breast milk is more than nourishment—it delivers circadian cues that may shape infant sleep, immunity, and metabolism. Researchers analyzing milk samples found that melatonin peaked at night and cortisol in the early morning, while other immune-related proteins remained steady.

This shows a brain and a night time backdrop.

Nighttime Brain Activity Keeps Glucose Levels in Check

A new study reveals that the brain actively maintains blood sugar stability during everyday life, not just during crises. Researchers identified VMHCckbr neurons in the hypothalamus that regulate glucose by promoting fat breakdown, especially during the early hours of sleep.

Math Reveals Why Sleep Patterns Shift With Age, Light, and Routine

A new study shows how math helps explain why babies nap erratically, teens stay up late, and older adults wake earlier. Researchers expanded the classic two-process sleep model by adding the effects of light exposure, uncovering how internal and external factors interact to regulate sleep.

How Your Body Clock Stays on Time Despite Temperature Changes

Researchers uncovered how our biological clocks keep a 24-hour rhythm even as temperatures fluctuate. Using physics-based models, they discovered that at higher temperatures, gene activity rhythms become distorted—rising faster and falling slower—to maintain the cycle’s duration.

Artificial Light Undermines Health: Aligning Modern Life With Biological Clocks

New research reveals that artificial light at night disrupts more than sleep, affecting immune function, metabolism, mood, and brain health. Circadian rhythms, finely tuned over millions of years, regulate critical biological processes and can be thrown off by modern lighting and irregular schedules.

Early Meals Boost Health, but Genetic Clock Shapes When We Eat

Our bodies process food differently depending on the time of day, and eating later has been linked to poorer metabolic health. A study of twins found that those who consumed most of their daily calories earlier had better insulin sensitivity and lower risk factors for diabetes and obesity.

Teen Sleep Patterns May Shape Brain Disorder Risk

Disrupting circadian rhythms during adolescence may alter how the brain responds to prenatal infections, a known risk factor for disorders like schizophrenia and autism. In a new mouse study, researchers found that each factor alone changed behavior and brain activity, but their combination produced unique effects—sometimes even counteracting one another.

Shared Genetic Signatures Found Across Psychiatric Disorders

Researchers have uncovered shared biological mechanisms across major psychiatric disorders by analyzing postmortem brain samples from the dorsolateral prefrontal cortex. Instead of looking at gene expression broadly, they zoomed in on the exon level—the building blocks that influence how proteins are made.

This shows people working at night and day.

Night Owls More Impulsive Than Morning Larks

A new study reveals that adolescents who identify as “night owls” tend to be more impulsive than their early-rising peers. These teens reported higher negative urgency and lower perseverance, meaning they were more likely to act rashly under stress and abandon difficult tasks.

Seasonal Sunlight Still Shapes Human Sleep

Despite modern lighting and lifestyle, human sleep patterns remain deeply influenced by seasonal changes in sunlight. New research reveals that our circadian rhythms track daylight shifts across seasons, impacting mood, sleep alignment, and overall health.
