Experts from the Basque research centre BCBL have shown for the first time that the way in which the activity of two brains is connected depends on whether the dialogue takes place in the native language or in a foreign language. Continue reading “The language of conversation impacts on the ‘synchronization’ of our brains”
Cannabis use in teens linked to risk of depression in young adults
While there has been a lot of focus on the role of cannabis use in psychosis, there has been less attention on whether cannabis use is associated with an increased risk of common mental health disorders, such as depression and anxiety. Continue reading “Cannabis use in teens linked to risk of depression in young adults”
Ancient DNA analysis unlocks secrets of Ice Age tribes in the Americas Research
Scientists have sequenced 15 ancient genomes spanning from Alaska to Patagonia and were able to track the movements of the first humans as they spread across the Americas at “astonishing” speed during the last Ice Age, and also how they interacted with each other in the following millennia. Continue reading “Ancient DNA analysis unlocks secrets of Ice Age tribes in the Americas Research”
Exercise might improve health by increasing gut bacterial diversity
Bacteria, often synonymous with infection and disease, may have an unfair reputation. Research indicates there are as many, if not more, bacterial cells in our bodies as human cells, meaning they play an important role in our physiology (1). In fact, a growing body of evidence shows that greater gut microbiota diversity (the number of different species and evenness of these species’ populations) is related to better health. Now, research published in Experimental Physiology has suggested that the efficiency with which we transport oxygen to our tissues (cardiorespiratory fitness) is a far greater predictor of gut microbiota diversity than either body fat percentage or general physical activity. Continue reading “Exercise might improve health by increasing gut bacterial diversity”
Researchers develop fire-retardant coating featuring renewable materials
Texas A&M University researchers are developing a new kind of flame-retardant coating using renewable, nontoxic materials readily found in nature, which could provide even more effective fire protection for several widely used materials. Continue reading “Researchers develop fire-retardant coating featuring renewable materials”
Bigger teams aren’t always better in science and tech
In today’s science and business worlds, it’s increasingly common to hear that solving big problems requires a big team. But a new analysis of more than 65 million papers, patents and software projects found that smaller teams produce much more disruptive and innovative research. Continue reading “Bigger teams aren’t always better in science and tech”
