Carriers of Alzheimer’s genetic marker have greater difficulty harnessing past knowledge

Adults carrying a gene associated with a higher risk of Alzheimer’s disease had a harder time accessing recently acquired knowledge, even though they didn’t show any symptoms of memory problems, according to findings published in a joint Baycrest-University of Oxford study. Researchers found that older adults carrying a specific strain Continue Reading

Study identifies possible genetic link between children’s language and mental health

A new study suggests there may be genetic explanations for why some children with poor language also have poor mental health. The University of York-led study examined genetic variants in six genes that are thought to contribute to language development in children. The researchers used Polygenic scoring, a statistical technique Continue Reading

Huntington’s disease triggered by genetic instability in brain cells, study finds

Huntington’s disease is triggered by genetic instability of a particular DNA sequence in brain cells, according to a new study of the lethal neurodegenerative disorder. If confirmed, the study could lead to new methods to prevent disease onset. It could also result in more accurate prediction of when healthy carriers Continue Reading

In a first, scientists map the genetic diversity of microbes residing in the human gut and mouth

How many stars are there in the observable universe? It was once deemed an impossible question, but astronomers have gleaned an answer—about one billion trillion of them. Now, scientists at Harvard Medical School and Joslin Diabetes Center have embarked on what could be a similarly daunting quest: How many genes Continue Reading

Disrupted genetic clocks in schizophrenia-affected brains reveal clues to the disease

Rhythms in gene expression in the brain are highly disrupted in people with schizophrenia, according to a new University of Pittsburgh-led study. The findings, published today by researchers from the Pitt’s School of Medicine in the journal Nature Communications, also suggest that researchers studying schizophrenia-linked genes in the brain could Continue Reading

Study identifies genetic differences that may increase risk of obesity, diabetes

In a Finnish study that included researchers from UCLA, the DNA from nearly 20,000 people was harnessed to identify genetic mutations that may increase the risk of diabetes, high cholesterol and other diseases and conditions. The findings, published in the journal Nature, suggest the potential for using genomic sequencing to Continue Reading
