Seasonal Variations In Cardiac-Related Hospitalizations For Aortic Dissection

According to new studies examined seasonal variations in cardiac-related hospitalizations specifically for aortic dissection and ST-Elevation Myocardial Infarctions (STEMI). The results of both studies revealed winter as the most common time for hospital admissions and used the Nationwide Inpatient Sample database (NIS) for analysis. Results were presented at the Society for Cardiovascular Angiography and Interventions (SCAI) Scientific Sessions in San Diego.

Astronauts Body Temperature Is Increased During Long-duration Space Missions

Humans’ core body temperature (CBT) is strictly controlled within a narrow range. Various studies dealt with the impact of physical activity, clothing, and environmental factors on CBT regulation under terrestrial conditions. However, the effects of weightlessness on human thermoregulation are not well understood. Specifically, studies, investigating the effects of long-duration spaceflight on CBT at rest and during exercise are lacking.

Glycine Formation By The Simple Amino Acids

A laboratory experiment that mimics astrophysical conditions, with cryogenic temperatures in an ultrahigh vacuum, scientists used an electron gun to irradiate thin sheets of ice covered in basic molecules of methane, ammonia and carbon dioxide. These simple molecules are ingredients for the building blocks of life. The experiment tested how the combination of electrons and basic matter leads to more complex biomolecule forms and perhaps eventually to life forms. The study was published in the Journal of Chemical Physics.
