The brain function of people addicted to cocaine is different from that of people who are not addicted and often linked to highly impulsive behavior, according to a new study … Continue Reading Neuroimaging study finds functional differences in brain communication in cocaine users.
A test that costs less than a $1 and yields results in minutes has been shown in newly published studies to be more sensitive and more exact than the current … Continue Reading Study finds $1 test using gold nanoparticles outperforms PSA screen for prostate cancer.
A new study from scientists at The Scripps Research Institute (TSRI) shows that nerve cells and blood vessels in the eye constantly talk to each other to maintain healthy blood … Continue Reading Study finds nerve cells and blood vessels in eye ‘talk’ to prevent disease.
Fragile X syndrome, an inherited cause of autism and intellectual disability, can have consequences even for carriers of the disorder who don’t have full-blown symptoms. Some carriers may experience social … Continue Reading New previously unseen cellular mechanism identified in Fragile X syndrome.
RNA is both the bridge between DNA and the production of proteins known to carry out the functions of life, guiding the amount and type of protein mades. As messenger … Continue Reading The first ever study to map splicing changes during T cell development has been published.
Repeated alcohol exposure during adolescence results in long-lasting changes in the region of the brain that controls learning and memory, according to a research team at Duke Medicine that used … Continue Reading Researchers find that repeated alcohol exposure during adolescence results in lasting impairments.
An enzyme secreted by the body’s fat tissue controls energy levels in the brain, according to new research from Washington University School. The data findings, in mice, underscore a role … Continue Reading Study shows that low body fat percentage is not good for the brain.
Using a simple device for eight hours a night to treat sleep apnea can help people with prediabetes improve their blood sugar levels and may reduce the risk of progressing … Continue Reading Study shows that effective sleep apnea treatment lowers diabetes risk.
A protein that normally fosters tissue repair instead acts to inhibit healing when sugar levels are high, according to a study in The Journal of Cell Biology. The data findings … Continue Reading Researchers map epigenetic cause of slowed diabetic wound healing.
Researchers have performed the first human-based study to identify calcium channels in cerebral arteries and determine the distinct role each channel plays in helping control blood flow to the brain. … Continue Reading Researchers show how calcium ion-channels control arterial tone and blood flow in the brain.
Human DNA accumulates damage over time, and older people’s bodies can’t repair it as well. Many scientists believe a build up of damage can cause cells to enter an irreversible … Continue Reading Study identifies molecular link between DNA damage and premature aging.
Every time a person makes a memory, somewhere in their brain a tiny filament reaches out from one neuron and forms an electrochemical connection to a neighbouring neuron. A team … Continue Reading Mapping the neuroanatomy of a memory.
A new study by Brown University neuroscientists details how the neocortex selectively samples from the flow of sensory information that might otherwise flood it. The team state that the usual … Continue Reading Researchers begin to map the corticothalamic pathway in selective neuroplasticity.
Newborn neurons generated from neural progenitor cells in a brain region called the hippocampus play an important role in learning and memory in adults. However, the molecular mechanisms that control … Continue Reading Researchers map epigenetic pathway of neurogenesis in the hippocampus.
About one in five people experience tinnitus, the perception of a sound, often described as ringing, that isn’t really there. Now, an opensource study in the journal Current Biology, has … Continue Reading Researchers begin to map and record tinnitus in the brain.
