Astronauts in crewed Mars missions could misread vital emotional cues

By Tania Fitzgeorge-Balfour, Frontiers science writer Long-exposure photo of the centrifuge used to simulate microgravity in the research subjects. Image: DLR Spending an extended period with reduced gravity, as would be experienced by astronauts on long space missions, may have a negative effect on cognitive performance, and in particular emotion recognition, reveals a new study. Hoping to counteract these changes, researchers found that short periods of artificial gravity did not have the desired effect. The findings of this study could have implications for effective teamwork in future space travel, especially for manned missions to Mars. Living for nearly 2 months in simulated weightlessness has a modest but widespread negative effect on cognitive performance that cannot be counteracted by short periods of artificial gravity, finds a new study published in Frontiers in Physiology. While cognitive speed on most tests initially declined but then remained unchanged over time in simulated microgravity, emotion recognition speed continued to worsen. In testing, research participants were more likely to identify facial expressions as angry and less likely as happy or neutral. ► Read original article► Download original article (pdf) “Astronauts on long space missions, very much like our research participants, will spend extended durations in microgravity, confined to […]

Just ten weeks of exercise can protect heart

— by Emily Barker, Just ten-weeks of exercise is nearly 100% effective at protecting the heart from potentially lethal changes in heart rhythms. Professor George Billman, Field Chief Editor of Frontiers in Physiology, works on preventing ventricular fibrillation, a very specific and potentially lethal change in cardiac rhythm, since 1980. In his current work, he has found that exercise could be the best non-pharmacological way to protect our hearts after sudden cardiac arrest. During ventricular fibrillation the heart does not beat in a coordinated fashion, instead it is a disorganized electrical event. “This is what you will see when they call a code blue and bring in a defibrillator to try to restore a cardiac rhythm,” he explained. The heart receives two sets of nerves, the sympathetic and the parasympathetic. A change in cardiac rhythms can be found when there is high sympathetic activity and low parasympathetic activity. To find the best way to protect the heart, Prof. Billman and his research team induced animals with a sudden cardiac arrest. They then put some of the animals on a ten week training program. About 95% of those who exercised were protected at the end of the program, whereas the sedentary animals got worse over time. […]
