Forgetful? Blame your house

Everyone has experienced the frustration of entering a room and forgetting what we were planning to do in there.

Autism’s facial characteristics revealed

Researchers from the University of Missouri have found distinct differences between the facial characteristics of children with autism compared to those of typically developing children. Because the face and brain develop in tandem, with each influencing the other, the researchers believe their findings could further our understanding of the origins of autism. “There is no […]

Scale of epigenetic changes observed in stimulated brain is “mind boggling”

In a discovery with major implications for treating psychiatric diseases and neurodegenerative disorders, Johns Hopkins neurologists have established that non-dividing brain cells, thought to be inherently stable, can instead undergo large-scale dynamic changes as a result of brain stimulation. Their findings are reported in Nature Neuroscience. Specifically, the researchers found evidence of an epigenetic change […]

Self-delusion a winning strategy in life

A mathematical model that simulates the effects of overconfidence shows that harboring a mistakenly inflated belief that we can easily meet challenges or win conflicts is beneficial in business, sport and war. The developers of the model, from the University of Edinburgh and the University of California, San Diego, use it to simulate the effects […]

In the new study, appearing in theProceedings of the National Academy of Sciences, the research team demonstrate […]

Forget about it

The notion that we can intentionally forget unwanted memories has been controversial ever since Freud proposed it at the beginning of the 20th century. Now, neuroimaging experiments show that Freud was correct and we can control what we forget. Swedish researcher Gerd Thomas Waldhauser, from Lund University, carried out the experiments with volunteers who were […]
