Memory

Two observational studies have found a link between e-cigarette use and cognitive complaints such as memory impairments and brain fog. The research doesn't present evidence of a causal link but calls for further long-term study into the relationship.

Engineers have created one of the smallest memory storage devices ever, made out of a 2D material measuring 1 nanometer square. The device works on the movements of single atoms, paving the way for memory systems with incredible information density.

Engineers at EPFL have created a new computer chip that can both process and store data in the same circuit. It’s made using a two-dimensional material called molybdenum disulfide, paving the way for smaller and more energy efficient electronics.

An intriguing new animal study is suggesting a hunger-regulating hormone secreted from the stomach may also influence memory and cognitive function. The study builds on a growing body of research into gut-brain communication via the vagus nerve.

A new study, led by researchers from University College London, is offering some of the first robust evidence showing how CBD, a key compound in cannabis, increases cerebral blood flow in memory processing regions of the brain such as the hippocampus.

New research suggests that blocking a specific neural pathway, associated with drug reward and withdrawal memories, could eliminate the triggers that lead to drug cravings and ultimately prevent relapse into addictive drug-taking behaviors.

A new type of data storage system could be denser, smaller, faster and more energy efficient than silicon chips. The new method involves encoding data in sliding stacks of two-dimensional layers of metals.

Researchers have discovered a new mechanism by which Alzheimer’s disease impairs memory recall. Neurons encoded with existing memories are drowned out by noise from neurons encoding new experiences. Silencing these allowed mice to regain lost memories.

Compelling research suggests neuronal activity in the hippocampus prior to the delivery of new information can enhance memory formation. The discovery points to a kind of "encoding mode" the brain enters in order to learn more effectively.

A team of researchers recently presented a font called Sans Forgetica, claiming it helps enhance memory. UK and New Zealand researchers have now put the font to the test, and reveal, while it may be difficult to read, it doesn't enhance memory.

A landmark study is offering the first evidence of a process by which our brains consolidate memories during sleep. The researchers witnessed neuronal firing patterns in humans during sleep that suggest we replay our waking experiences as we rest.

New research from an international team of scientists has tracked a compelling series of connections between the gut microbiome and memory, illustrating how genetics can influence memory via bacterial metabolites produced in the gut.
