A new study shows that sleeping after processing new information is most effective. Titled “Memory for Semantically Related and Unrelated Declarative Information: The Benefit of Sleep, the Cost of Wake,” the study was published March 22 in PLOSOne.
Snorting, gasping, or short interruptions in breathing during sleep (sleep apnea) may be linked to depression symptoms, new research shows.
Like the mute button on the TV remote control, our brains filter out unwanted noise so we can focus on what we’re listening to. But when it comes to following our own speech, a new brain study from the University of California, Berkeley, shows that instead of one homogenous mute button, we have a network of volume settings that can selectively silence and amplify the sounds we make and hear.
Just as the familiar sugar in food can be bad for the teeth and waistline, another sugar has been implicated as a health menace and blocking its action may have benefits that include improving long-term memory in older people and treating cancer. Progress toward finding such a blocker for the sugar — with the appropriately malicious-sounding name “oh-glick-nack” — was the topic of a report at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society.
A hidden and never before recognized layer of information in the genetic code has been uncovered by a team of scientists at the University of California, San Francisco (UCSF) thanks to a technique developed at UCSF called ribosome profiling, which enables the measurement of gene activity inside living cells — including the speed with which proteins are made.
