How deep breaths help with relaxation -- Interview by Kevin Yackle!

The one advice for relaxation is to take deep breaths. Yoga practitioners and doctors alike give this age-old advice. But how does our body connect breathing with calmness? Or is this a placebo effect??

Kevin and colleagues wanted to understand the biological connection between breathing and relaxation. For this, they targeted a specific region in the brain that is involved in controlling breathing. They killed a small region within this special area. Surprisingly, and fortunately, the animal's breathing did not stop. But it was slower, and was connected to the animal being calm under normal conditions! This showed a link between deep, slow breaths and a relaxed state of mind. To know more, please listen to Kevin.

It's an emergency! Interview with Gesa Zander on cellular response to heat stress!

Imagine a sudden crisis within a country. One day, suddenly, there is a need to face an impending disaster. What happens? The people go into panic-mode and stop doing their regular jobs, and instead focus on averting the crisis. Normal production ceases, and things needed to face the disaster are produced. The pace of production is ramped, and irrespective of the quality, a huge quantity of emergency supplies is generated.

Like humans, cells in our body also face crisis. They need to adapt to extreme environments quickly in order to survive and thrive. Gesa, Alexandra, Lysann and colleagues wanted to know what happens to the cellular production process during the stress period. How does the cell switch to producing cell-responsive genes. And not only producing, but producing at a fast-pace. Are the quality controls applicable during normal times also applicable during the frantic response to stress. They find that the cell switches to stress-control mode, and for a certain time, eases on the quality controls of production. Please listen to Gesa on the interesting adaptability of the cells.
