It’s common knowledge that our brains—and, specifically, our brain cells—store memories. But a team of scientists has discovered that cells from other parts of the body also perform a memory function, opening new pathways for understanding how memory works and creating the potential to enhance learning and to treat memory-related afflictions.
“Learning and memory are generally associated with brains and brain cells alone, but our study shows that other cells in the body can learn and form memories, too,” explains New York University’s Nikolay V. Kukushkin, the lead author of the study, which appears in the journal Nature Communications.
The research sought to better understand if non-brain cells help with memory by borrowing from a long-established neurological property—the massed-spaced effect—which shows that we tend to retain information better when studied in spaced intervals rather than in a single, intensive session—better known as cramming for a test.

If you ever tried cramming all your learning in one night before the exam, you know it doesn’t usually work. Surprisingly, this has little to do with the brain.

Study shows kidney and nerve tissue cells learn and make memories in ways similar to neurons.
We all want to ‘age successfully’ with as few health issues as possible. A new study suggests getting more than seven hours of sleep a night could go a long way to achieving that goal.
The study involved 3,306 participants aged 45 and over, whose sleep habits were recorded in 2011, 2013, and 2015, followed by a health check five years later. The data, analyzed by a team from Wenzhou Medical University in China, showed that those who bank at least seven hours of sleep a night tend to have significantly better health later in life.
“Successful aging was evaluated in 2020 and was defined as being free of major chronic diseases, no physical impairment, high cognitive function, good mental health, and active engagement with life,” write the researchers in their published paper.
Novel magnetic nanodiscs could provide a much less invasive way of stimulating parts of the brain, paving the way for stimulation therapies without implants or genetic modification, MIT researchers report.
The scientists envision that the tiny discs, which are about 250 nanometers across (about 1/500 the width of a human hair), would be injected directly into the desired location in the brain. From there, they could be activated at any time simply by applying a magnetic field outside the body. The new particles could quickly find applications in biomedical research, and eventually, after sufficient testing, might be applied to clinical uses.
The development of these nanoparticles is described in the journal Nature Nanotechnology, in a paper by Polina Anikeeva, a professor in MIT’s departments of Materials Science and Engineering and Brain and Cognitive Sciences, graduate student Ye Ji Kim, and 17 others at MIT and in Germany.
A mysterious electromagnetic mechanism may be more important than the firing of neurons in our brains to explain our awareness.
By Tamlyn Hunt
The neuron, the specialized cell type that makes up much of our brains, is at the center of today’s neuroscience. Neuroscientists explain perception, memory, cognition and even consciousness itself as products of billions of these tiny neurons busily firing their tiny “spikes” of voltage inside our brain.
In addition to lowering your cholesterol, keeping your brain healthy and improving mental health, new research from the University of Georgia suggests omega-3 and omega-6 fatty acids may help ward off a variety of cancers.
The study relied on data from more than 250,000 people and found that higher…
But most Americans probably aren’t eating enough of these foods to reach the recommended amounts.
That’s why many individuals turn to fish oil supplements. They’re one of the most popular dietary pills on the market and for good reason.
Previous studies suggest omega-3 supplements can reduce the risk of developing high cholesterol and lower the risk of heart disease.
Nanomagnets keep a history of their states and can be trained in a few hours.
Jungfleisch uses nanomagnets to store and transmit information and achieves it in a more energy-efficient manner as compared to electrons.
