People faced with more options than they can effectively consider want to make a good decision, but feel they’re unable to do so, according to the results of a novel study from the University at Buffalo that used cardiovascular measures and fictional dating profiles to reach its conclusions. Despite the apparent opportunities presented by a …

The key dose of nature for health

Research led by the University of Exeter, published in Scientific Reports and funded by NIHR, found that people who spend at least 120 minutes in nature a week are significantly more likely to report good health and higher psychological wellbeing than those who don’t visit nature at all during an average week. However, no such …

Blood pressure doesn’t drop during a sauna

Contrary to the previous assumption, blood pressure does not drop during a sauna session – it rises. And this increase is even comparable to the increase caused by a short, moderate workout. This is one of the conclusions of a recent study carried out by sports scientists at the Martin Luther University Halle-Wittenberg (MLU) in …

Danger avoidance can be genetically encoded 

An organism’s phenotype can change during its lifetime due to epigenetic mechanisms. For example, in the microscopic roundworm Caenorhabditis elegans, starvation or heat stress prompts animals to adapt to these conditions by varying the expression of multiple genes. At the level of the genome, these changes can be made durable by altering how tightly the …

Understanding epigenetic causes of disease

Epigenetics is a system for molecular marking of DNA – it tells the different cells in the body which genes to turn on or off in that cell type. But the cell-specific nature of epigenetics makes it challenging to study. Whereas a blood sample can be used to ‘genotype’ an individual, most epigenetic marks in …
