To make memories, new neurons must erase older ones Short-term memory may depend in a surprising way on the ability of newly formed neurons to erase older connections. That's the conclusion of a report in the November 13th issue of the journal Cell, a Cell Press publication, that provides some of the first evidence in mice and rats that new neurons sprouted in the hippocampus cause the decay of short-term fear memories in that brain region, without an overall memory loss. The researchers led by Kaoru Inokuchi of The University of Toyama in Japan say the discovery shows a more important role than many would have anticipated for the erasure of memories. They propose that the birth of new neurons promotes the gradual loss of memory traces from the hippocampus as those memories are transferred elsewhere in the brain for permanent storage. Although they examined this process only in the context of fear memory, Inokuchi says he "thinks all memories that are initially stored in the hippocampus are influenced by this process."

Protein that destroys HIV discovered Loyola University researchers have identified the key components of a protein called TRIM5a that destroys HIV in rhesus monkeys. The finding could lead to new TRIM5a-based treatments that would knock out HIV in humans, said senior researcher Edward M. Campbell, PhD, of Loyola University Health System. Campbell and colleagues report their findings in an article featured on the cover of the Sept. 15, 2010 issue of the journal Virology, now available online. In 2004, other researchers reported that TRIM5a protects rhesus monkeys from HIV. The TRIM5a protein first latches on to a HIV virus, then other TRIM5a proteins gang up and destroy the virus.

New research from the University of California, Berkeley, shows that an hour’s nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter. Students who napped (green column) did markedly better in memorizing tests than their no-nap counterparts.

Hash Oil Hash oil, AKA hashish oil, is a firm liquid made by dissolving high-THC cannabis and/or hash in a solvent (like alcohol, petroleum, acetone and others).

Some of the experiments psychologists have conducted over the years reveal things about the way we humans think and behave that we might not want to embrace, but which can at least help keep us humble. That's something. 1.
