Astrocytes, Not Neurons, Hold the Key to Emotional Memory

New research reveals that astrocytes — not neurons — are responsible for stabilizing emotional memories by re-engaging during recall. After an emotionally intense event, such as fear, specific astrocytes become biologically tagged with adrenoreceptors, making them responsive when the memory is later reactivated.

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.

Placebo Triggers Brain’s Opioid System to Relieve Pain

Researchers have successfully induced the placebo effect in rats, uncovering the neural mechanisms behind how belief in pain relief can reduce the perception of pain. Using conditioning, rats learned to associate injections with pain relief, and later exhibited reduced pain responses even when injected with saline.

Acetate and Bacteria Team Up to Burn Fat

A new study reveals that acetate—when paired with specific gut bacteria—can significantly reduce fat and liver mass in both normal and obese mice. Researchers used a supplement called AceCel, which delivers acetate directly to the large intestine, promoting the growth of Bacteroides bacteria.

The Brain Learns to Fear Through Inference, Not Just Experience

A new study reveals how rats can learn to fear through inference, offering insights into the neural basis of higher-order emotions. By pairing a neutral sound and image, then associating the image with an unpleasant experience, researchers showed that rats later feared the sound alone—demonstrating inferred emotional learning.

One Gene Mutation Disrupts Both Immunity and Brain Development

Researchers have uncovered a surprising mechanism by which a single genetic mutation in the BCL11B gene causes both immune dysfunction and brain development issues. Instead of merely disabling the protein’s normal function, the mutated BCL11B protein interferes with other healthy proteins, such as BCL11A, causing broader damage.

Sleep Strengthens Emotionally Charged Memories During Non-REM Phase

Researchers have discovered that positive emotions enhance perceptual memories during sleep, particularly in the non-REM stage. Using mice, they found that memories linked to rewarding experiences lasted longer than neutral ones.

This shows people connected in a network.

How Large Social Circles Foster Trust

A new study challenges the belief that larger groups reduce cooperation, showing instead that flexible social connections enhance teamwork. Researchers found that in a prisoner’s dilemma game, participants in bigger groups cooperated more frequently, despite memory limitations.

Unique Brain Plaques Linked to Alzheimer’s Mutation Decoded

Researchers have identified the structure of amyloid beta fibrils linked to a rare inherited form of Alzheimer’s disease caused by the Arctic mutation. Using cryo-electron microscopy and NMR, they revealed a W-shaped fibril structure that explains the formation of cottonwool plaques—large, spherical brain structures unique to this mutation.

Study Sheds Light on Stem Cell Aging Process

Scientists identified key changes in chromosome structure and gene expression that contribute to stem cell exhaustion during aging. Using fruit flies, they discovered that blocking the gene ced-6 led to stem cell depletion, even in young organisms.

Dopamine Treatment Reduces Alzheimer’s Plaques

Researchers uncovered a promising approach to treating Alzheimer’s disease by using dopamine to enhance brain enzyme activity that reduces harmful plaques. Conducted on mice, the study shows that dopamine increases neprilysin production, which breaks down beta-amyloid plaques linked to Alzheimer's.

Indirect Genetic Influences of Autism Revealed

Researchers made a significant breakthrough in understanding the genetics of autism spectrum disorder (ASD) by focusing on special genetic mutations and their impact on neighboring genes. The study shows that mutations within promoters in certain genome regions can indirectly affect ASD-related genes due to the three-dimensional structure of the genome.
