Are you sticking to your diet? Scientists may be able to tell from a blood sample

An analysis of small molecules called “metabolites” in a blood sample may be used to determine whether a person is following a prescribed diet, scientists at Johns Hopkins Bloomberg School of Public Health have shown. Clinical trials of diets and their health impacts are often plagued by participants’ poor adherence to assigned diets, which can make it difficult or even […]

Researchers investigate changes in white matter in mice exposed to low-frequency brain stimulation

A team of researchers at the University of Oregon has learned more about the mechanism involved in mouse brain white matter changes as it responds to stimulation. In their paper published in Proceedings of the National Academy of Sciences, the group describes the experiments they conducted and what they found. Prior studies of the brain have shown that white matter […]

To share or not to share? Physiological and social determinants of children’s sharing behavior

When are primary school children willing to share valuable resources with others and when are they not? A team of researchers from the University of Vienna led by cognitive biologist Lisa Horn investigated this question in a controlled behavioural experiment. The motivation to share seems to be influenced by group dynamical and physiological factors, whereas friendship between the children seems […]

What does it mean to be moved by love?

Researchers from UCLA and the University of Oslo have documented a complex but universally felt emotion they call kama muta—a Sanskrit term that means “moved by love.” For the past five years they have documented the physical sensations people report when they feel kama muta, and what kind of events, images and experiences bring it about. For the research, which […]

Study identifies protein’s role in mediating brain’s response to stress

A study led by Massachusetts General Hospital (MGH) investigators has identified a critical role for a protein called Kruppel-like factor 9 (Klf9) in the brain’s response to stress, which has implications for protecting against the effects of stress in conditions like major depression and post-traumatic stress disorder (PTSD). In their paper published in Cell Reports, the team describes finding that […]

Brain matures faster due to childhood stress

Stress in early childhood leads to faster maturation of certain brain regions during adolescence. In contrast, stress experienced later in life leads to slower maturation of the adolescent brain. This is the outcome of a long-term study conducted by researchers of Radboud University in which 37 subjects have been monitored for almost 20 years. The findings will be published in […]
