Hungry Brain Rewrites Emotional Priorities

New research reveals that hunger can flip female mice from nurturing to aggressive—but only during specific hormonal phases. Scientists discovered that neurons controlling appetite (AgRP neurons) interact with a brain region linked to parental care, the medial preoptic area (MPOA).

Long-Term Keto Diet May Damage Your Body

A new study reveals that while the ketogenic diet can prevent weight gain, it may cause severe long-term metabolic problems. Researchers found that mice on a long-term keto diet developed fatty liver disease and impaired blood sugar regulation due to stressed pancreatic cells.

Hearing Voices May Stem from the Brain Misreading Its Own Inner Speech

A new study reveals that auditory hallucinations in schizophrenia may arise when the brain fails to recognize its own inner voice as self-generated. Normally, the brain predicts the sound of one’s inner speech and dampens auditory responses accordingly, but this prediction breaks down in people who hear voices.

This shows the outline of a head. Inside is images from past times, reflecting memory.

What Makes Certain Memories Impossible to Forget?

Scientists are asking the public to share their most vivid memories to uncover why some moments feel as fresh as the day they happened. The project blends cognitive neuroscience with literature, examining how vivid memories are experienced, evolve with age, and even differ across centuries.

When a Hug Turns Dark: How Manipulative Partners Use Touch

Touch can strengthen bonds and calm stress, but not all affection is sincere. A new study reveals that people with “dark triad” traits—narcissism, psychopathy, and Machiavellianism—often use physical touch to control or manipulate their romantic partners.

This shows the outline of two heads and brains.

Tobacco and Cannabis Together Alter Brain’s “Bliss Molecule” System

People who use both cannabis and tobacco show unique brain chemistry linked to higher anxiety, depression, and difficulty quitting. Brain scans revealed increased levels of FAAH, an enzyme that breaks down the brain’s “bliss molecule,” anandamide.

Your Brain Navigates Mental Maps Differently Than Real Ones

When you picture a map in your mind, your brain uses different pathways than when you actually look at one. In a study on spatial attention, participants recalled the map of France and judged which city was closer to Paris.

This shows a brain and a castle in the clouds.

How the Brain Learns New Facts About Imaginary Worlds

Learning new information about the world—like details from a fantasy realm—engages brain regions distinct from those used to recall personal experiences. In a new study, participants learned fictional facts about imaginary civilizations and were later tested on what they remembered.

How Storytelling Style Shapes the Way the Brain Forms Memories

The way an event is described—through feelings or sensory detail—changes how the brain stores and recalls it. In this study, participants listened to stories that emphasized either conceptual details (thoughts and emotions) or perceptual details (sights and sounds).

Theta Brain Waves Act Like Radar to Boost Visual Working Memory

New research shows that the brain’s ability to detect subtle visual changes—like spotting an anomaly on a security monitor—depends on theta-frequency brain waves (3–6 Hz) that rhythmically sweep across the cortex. These traveling waves act like a radar, scanning different parts of the visual field and influencing when and where attention peaks.

First Signs of Multiple Sclerosis Found Years Before Symptoms

Researchers have traced the earliest stages of multiple sclerosis (MS), showing that the immune system begins attacking the brain up to seven years before diagnosis. By analyzing over 5,000 blood proteins, they identified molecular signs of damage to myelin—the protective sheath around nerve fibers—long before symptoms emerge.

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.
