Widespread brain shrinkage drives aging-related memory decline, mega-analysis finds

An international mega-analysis of over 10,000 MRI scans and 13,000 memory tests from thousands of healthy adults shows that memory decline with age stems from broad structural brain changes across many regions—especially, but not exclusively, the hippocampus—with nonlinear acceleration in later life and not fully explained by Alzheimer's risk genes like APOE ε4. This points to a distributed brain vulnerability that could help identify at-risk individuals and guide personalized cognitive health interventions.

Pioneering cognitive chimp Ai dies at 49, leaving legacy in primate mind research

Ai, a female chimpanzee at Kyoto University's Ai Project famed for numeracy, color naming, and painting, died at 49 from old age and organ failure, surrounded by staff; arriving in 1977 from West Africa, she helped drive decades of primate cognition research.

Arcuri: Micron's AI-Driven Memory Upswing Has Legs

UBS analyst Timothy Arcuri, after investor meetings, says Micron’s upcycle is durable thanks to AI-driven memory demand, with capacity additions taking a long time and memory shifting from a commodity to a strategic asset. He lifted 2026 and 2027 EPS estimates and raised the price target to $400 (roughly 16% upside) while keeping a Buy rating; overall sentiment among analysts remains bullish, though the average target (~$329) implies some downside risk in the near term.

Memory's Dual Libraries: Distinct Neuron Groups Encode Content and Context

A Bonn-led study finds that the human brain stores memory content and its context in separate neuron populations—content neurons fire for specific items, context neurons for the task or situation—whose coordinated interactions enable flexible recall through pattern completion.

Brain Enzyme Tied to Memory Reveals New Alzheimer’s Treatment Path

Johns Hopkins researchers found that loss of the brain enzyme cystathionine γ-lyase (CSE), which makes hydrogen sulfide, causes memory loss and Alzheimer’s-like brain damage in mice, highlighting CSE as a potential drug target to boost brain health and slow neurodegeneration.

Scientific Explanation for December's Earlier Arrival Each Year

The article explains how our perception of time is influenced by brain processes, with time seeming to pass faster when engaged in novel or exciting activities and slower during routine or boring moments. It highlights that our brains infer time based on change and memory density, which explains why years feel short when routines dominate and why time seems to fly as we age. To make time feel longer, creating new memories and experiences is recommended.

The Impact of Sound on Word Influence

Research suggests that words with unusual sound sequences, which are more surprising and vivid, are processed more deeply and remembered better, challenging the traditional view that word-meaning relationships are arbitrary. This insight could enhance communication strategies across various fields.

Couples Experience Shared Memory Loss, Study Finds

New research shows that romantic partners synchronize their brain activity during storytelling, leading to a shared form of forgetting where they tend to forget related details, a phenomenon less observed among strangers. This neural alignment, especially in the prefrontal cortex, facilitates a shared reality but may cause loss of individual memories, highlighting how close relationships influence cognitive processes.

Revealing the Brain's Hidden Astrocyte Cells and Their Role in Behavior and Health

Recent research reveals that astrocytes, once considered support cells, play crucial roles in shaping behavior, memory, and health by regulating the environment around neurons, influencing brain functions such as circadian rhythms and memory encoding, and potentially contributing to neurological diseases.

Decoding the Brain's Mechanisms for Memory Durability

Recent neuroscience research reveals that long-term memories are formed through a sequence of molecular timers across different brain regions, particularly involving the thalamus, cortex, and hippocampus. These timers regulate whether memories are stabilized or fade, with gene programs like Camta1, Tcf4, and Ash1l playing crucial roles. This understanding could lead to new treatments for memory-related diseases such as Alzheimer's.

Key Action to Prevent Alzheimer's Symptoms

Research suggests that getting sufficient deep sleep may help delay or reduce Alzheimer's symptoms by supporting memory and brain health, even in individuals with high levels of Alzheimer's-related proteins. Improving sleep quality through lifestyle changes could be a promising way to protect cognitive function as we age.
