Immune cells are like the Hatfields and McCoys of our bodies--once wronged, they never, ever forget. This is how we gain immunity, and it’s why vaccines work: Immune cells develop a memory of an invading pathogen, and they build an alert system to find and fight it should it ever return. But a new study by Stanford researchers adds a new wrinkle to this long-held immune theory. It turns out immune cells can develop this memory-like state even for pathogens they’ve never met. This may come from exposure to harmless microbes -- or the memories may actually be borrowed from other, more experienced cells.

A study by Johns Hopkins researchers has shown that a widely accepted model of long-term memory formation -- that it hinges on a single enzyme in the brain -- is flawed. The new study, published in the Jan. 2 issue of Nature, found that mice lacking the enzyme that purportedly builds memory were in fact still able to form long-term memories as well as normal mice could.

Hunger would seem to be a fairly straightforward instinct: Depending on how much you eat, you either will or you won't be hungry afterward. As it turns out, our relationship to food may not be so simple. A new study, published this week in the journal PLoS ONE, adds a new wrinkle by suggesting our short-term memory also may play a role in appetite. Several hours after a meal, the study authors found, people’s hunger levels were predicted not by how much they’d eaten, but rather by how much food they’d seen in front of them—in other words, how much they remembered eating.

Many children spontaneously report memories of 'past lives'. For believers, this is evidence for reincarnation; for others, it's a psychological oddity. But what happens when they grow up?

UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer's disease during sleep. They discovered that this part of the brain behaves as if it's remembering something, even under anesthesia, a finding that counters conventional theories about memory consolidation during sleep.

If you aren't able to master a tune even after hours of practicing, then perhaps you should sleep on it. We mean try sleeping while the tune is being played in the background.

Memories can form in even very young children, it seems, but it is not clear that they can be retrieved.

One of the brain's jobs is to help us figure out what's important enough to be remembered. Scientists have achieved some insight into how fleeting experiences become memories in the brain.

For most of us, it's tricky enough to remember what we were doing this time last week, let alone on some random day years ago. But for a blind 20-year-old man referred to by researchers as HK, every day of his life since the age of about eleven is recorded in his memory in detail. HK has a rare condition known as hyperthymesia and his is only the second case ever documented in the scientific literature (the first, a woman known as AJ, was reported in 2006.

Who owns your memories? You’d think that would be you. But in a short interview with Claudia Dreifus at the New York Times, neuroethicist Matthew Liao notes that to the extent our devices are serving as outsourced personal memory banks, you may be sharing ownership with, say, Facebook:

John Smart, co-founder of the Brain Preservation Foundation—an organization dedicated to the study of maintaining brain function after our biological death—argues that the "redundant, resilient and distributed" nature of long-term memory makes it possible to preserve significant portions of our identity after death.
