Scientists Show How We Remember Dreams

But they're still not sure about the 'why' part

(Newser) - From the scariest nightmares to the most bizarre fantasies, some dreams are remembered forever, and a team of Italian scientists knows how.

How Naps Can Help You Learn

New study shows a post-snooze memory boost

(Newser) - If you’re a fan of the afternoon nap, there’s no need to be ashamed—in fact, new research gives you the perfect excuse to stop reading this right now and go grab some midday shuteye. In the study, volunteers who napped for 100 minutes prior to completing a... More »

'Puberty Pill' Could Make Kids Smarter

Drug would act on brain, blocking receptor that slows learning

(Newser) - Studying, schmudying: A pill that boosts teenagers’ ability to learn may be in the pipeline soon.

Give kids a steroid to suppress that receptor, and... More »

To Get Smarter, Take a Nap

Sleeping for 90 minutes at midday boosts the brain's ability to learn

(Newser) - Taking a nap after lunch helps the brain "reset" and prepare to assimilate new information, researchers say. "It's as though the e-mail inbox in your hippocampus is full and, until you sleep and clear out those fact e-mails, you're not going to receive any more mail," says... More »

New Brain Cells Bump Old Memories

Study finds new neurons clear out short-term memory

(Newser) - The birth of new brain cells bumps old memories into long-term storage, according to new research which upends earlier theories. Researchers working with rodents found that the creation of new neurons destabilized existing connections in the hippocampus instead of strengthening them as they had expected, effectively "clearing the inbox"...

Scientists Read Subjects' Location From Brain Scans

(Newser) - Decoding part of the complex system used by the brain to store memories has allowed scientists to determine a person’s location by looking at brain scans, Wired reports. A study took images of the hippocampus—the part responsible for spatial relationship and short-term memories—as individuals navigated a virtual-reality... More »

Big Differences Found in Male, Female Brains

They're apparently based on different genetic blueprints, studies find

(Newser) - The brains of men and women are so physically different they amount to different organs and may have developed from distinct genetic blueprints, new research shows. Distinct anatomical differences between male and female brains likely explain many well-established differences of perception and behavior between the sexes, from problem-solving strategies to...
