Memory

Most memory devices us electric signals, but an emerging technology uses light, so data can be read back just by checking if an LED is on or off. Now, researchers have developed a new device based entirely on perovskite that can do both at once.

Animals, like us, experience a deterioration of memory in old age. But a new study suggests that cuttlefish are the first species in which this appears not to be the case.

For over a century scientists have known taking breaks while learning can improve long-term memory retention. A new study offers some of the first evidence to show how this actually works in the brain.

A new study has found caffeine can be used to help bees locate specific flowers. The research suggests the drug enhances bee memory and makes them more efficient at homing in on certain targeted flowers.

An intriguing study is proposing an innovative method to treat age-related memory loss. The preclinical research shows memory decline in aging mice can be reversed by manipulating the composition of structures in the brain known as perineuronal nets.

A new imaging study comparing brain activity of superagers to youthful brains highlights exactly how some older adults can maintain good memory function, and directs researchers to brain regions that could be stimulated to enhance memory in aging adults.

Our brains are extremely fast at recognizing the faces of people important to us. Now, a new study has identified a previously unknown population of brain cells that may be hybrids of sensory and memory neurons, which enable this quick recall.

Scientists have uncovered some surprising news ways ultrasound can improve cognition in mouse models of Alzheimer's disease, something they believe could have wider implications for restoring cognition in the elderly.

Through a new study on rodents, scientists have made first-of-a-kind observations of the brain mistakenly recalling a memory, which they believe lays the groundwork for understanding the mechanisms at play in conditions like Alzheimer's disease.

Scientists at King's College London have used experiments in mice to demonstrate how fasting can also improve long-term memory and tackle age-related cognitive impairment, by boosting expression of what's known as the "longevity gene."

A new study suggests handwriting on paper leads to greater brain activity and memory retention than using a stylus on a tablet. The researchers hypothesize the spatial details of writing on paper may explain why it enhances the encoding of information.

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.
