Losing Sleep Might Make You Hungrier and Sleepier Later

New research using fruit flies reveals that sleep loss can trigger both increased eating and sleeping—if the deprivation leads to energy depletion. Flies that lost energy while sleep-deprived compensated with extra rest and food intake, while those deprived without losing energy showed no such rebound.

Why Kids Still Struggle With Capital Letters After Grade School

New research reveals that English-speaking children continue to refine their capitalization skills well past the early grades, despite being taught the rules early. Across two studies, students in Grades 3–6 made more errors than older students and relied more heavily on having “two clues”—such as a proper noun at the start of a sentence—to capitalize correctly.

Don’t Ignore the Winter Blues, It Could Be Seasonal Depression

As daylight fades, many experience fatigue or low mood—but for millions, these symptoms signal seasonal affective disorder (SAD), a serious form of depression. Reduced sunlight disrupts serotonin, melatonin, and the body’s circadian rhythm, leading to feelings of hopelessness, loss of interest, and sleep or appetite changes.

How Chocolate’s Puckering Taste May Stimulate the Brain

Japanese researchers have uncovered how the astringent “bite” of cocoa flavanols can activate the brain—even though little of the compound enters the bloodstream. In mice, the sensation of astringency triggered sensory nerves that stimulated neurotransmitters linked to motivation, alertness, and memory.

Rotating Brain Waves Help the Mind Refocus After Distraction

Neuroscientists have discovered that when the brain is distracted, coordinated “rotating” waves of neural activity help it steer back to focus. Using electrical recordings in animals, the team found that neurons in the prefrontal cortex synchronize in circular patterns—like starlings in flight—to recover from cognitive interruptions.

How “Frazzled” Keeps the Brain Wired for Lightning-Fast Communication

Scientists have uncovered a key role for the protein “Frazzled” in building and maintaining the rapid neural connections that allow fruit flies to react in milliseconds. When Frazzled is missing, neurons lose vital gap junctions, slowing communication and weakening muscle responses.

Human Mind Prefers Simple Explanations Over Complex Truths

New research shows that people tend to prefer simple explanations even when complex ones are more accurate. The study found that individuals focus mainly on visible or known causes while neglecting hidden or absent ones, leading to oversimplified reasoning.

Newly Mapped Brain Circuit Reveals How Memories Stay Stable During Learning

A new study reveals how brain circuits between the entorhinal cortex and hippocampus stabilize memories during learning. Researchers found that synchronized signals between excitatory and inhibitory neurons in these regions help strengthen “place maps,” ensuring memories remain consistent even as new information is learned.

Common Antidepressant Eases Core Symptoms Within Two Weeks

A new analysis of the PANDA clinical trial reveals that sertraline, one of the most prescribed antidepressants, improves key emotional symptoms of depression—such as sadness, self-loathing, and suicidal thoughts—within just two weeks of treatment. Using network analysis to assess individual symptoms, researchers found that the drug also eased anxiety early on, while somatic effects like fatigue and low libido appeared but later stabilized.

Toddler Gut Bacteria Linked to Childhood Anxiety and Depression

A new study suggests that a child’s gut microbiome at age 2 may influence their emotional health years later. Researchers found that higher levels of bacteria from the Clostridiales order and Lachnospiraceae family were linked to stronger connectivity across emotion-related brain networks and a higher risk of anxiety and depression symptoms by age 7½.

$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.

How Chemotherapy Triggers Nerve Damage, and How to Stop It

A new study reveals that chemotherapy-induced nerve pain arises from a stress response in immune cells that triggers inflammation and neurotoxicity. Researchers found that activating a cellular stress sensor called IRE1α causes nerve damage and pain during chemotherapy, but blocking it prevents both in mice.
