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 …

Human brains: tuned for musical pitch

“We found that a certain region of our brains has a stronger preference for sounds with pitch than macaque monkey brains,” said Bevil Conway, Ph.D., investigator in the NIH’s Intramural Research Program and a senior author of the study published in Nature Neuroscience. “The results raise the possibility that these sounds, which are embedded 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 …

Economic downturns linked to children’s mental health

Research linking economic conditions and health often does not consider children’s mental health problems. In a new Health Economics study, investigators found that U.S. children’s mental health worsened as the economy weakened. The use of special education services for emotional problems also rose when economic conditions worsened. The study, which drew on data from 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 …

The body responds to variations in light independently of the brain

During the day, we experience a series of physical, mental and behavioural changes know as circadian rhythms. These changes are governed by a central clock, located in the hypothalamus, which lies in the centre of the brain. This clock is responsible for synchronizing our tissues to ensure that their functions are coordinated and that they …

Magnetic therapy for concussion symptoms 

Concussion symptoms–such as loss of balance, hazy comprehension, sleep disturbance and ability to walk straight–can be reversed by a new type of magnetic stimulation, research at the University of Saskatchewan (USask) shows. Magnetic stimulation using a laptop-style device for 20 minutes per day improved the ability of rodents with concussion to walk in a straight …

Cranberries work with antibiotics to fight bacteria

Cranberries are highly sought after for their tangy taste and the antioxidants they contain, but a new study published in the journal Advanced Science provides evidence that they could also help in the fight against bacteria. When treated with molecules derived from cranberries, pathogenic bacteria become more sensitive to lower doses of antibiotics. What’s more, …

A simple stress test

Stress is often called “the silent killer” because of its stealthy and mysterious effects on everything from heart disease to mental health. Now researchers at the University of Cincinnati have developed a new test that can easily and simply measure common stress hormones using sweat, blood, urine or saliva. Eventually, they hope to turn their …
