Ability to turn off genes in brain crucial for learning, memory

Every time you play a game of basketball, make a cup of coffee or flick on a light switch, you are turning on genes in your brain. These same genes typically are turned off when the activity ceases - but when that doesn't ...

Swapping sick for healthy brain cells slows Huntington's disease

Researchers have successfully reduced the symptoms and slowed the progression of Huntington's disease in mice using healthy human brain cells. The findings, which were published today in the journal Nature Communications, ...

Effects of maternal smoking continue long after birth

Early exposure to nicotine can trigger widespread genetic changes that affect formation of connections between brain cells long after birth, a new Yale-led study has found. The finding helps explains why maternal smoking ...

Teen brains facilitate recovery from traumatic memories

Unique connections in the adolescent brain make it possible to easily diminish fear memories and avoid anxiety later in life, according to a new study by Weill Cornell Medicine researchers. The findings may have important ...

Neurobiologists restore youthful vigor to adult brains

They say you can't teach an old dog new tricks. The same can be said of the adult brain. Its connections are hard to change, while in children, novel experiences rapidly mold new connections during critical periods of brain ...

Age-related hepatitis B infection and the gut microbiome

(Medical Xpress)—The hepatitis B virus (HBV), which affects the liver, behaves differently in different people depending on genetics and the age the person is when infected. Ninety-five percent of adults who contract hepatitis ...

Bio-X scientists develop decoy drug to aid ailing brain

A team of Stanford Bio-X scientists has restored the ability of adult mice to form new connections in the brain. If the finding works in people, it has the potential to help adults recover from stroke and forms of blindness ...

A new way to model cancer

Sequencing the genomes of tumor cells has revealed thousands of mutations associated with cancer. One way to discover the role of these mutations is to breed a strain of mice that carry the genetic flaw—but breeding such ...
