Population density and virus strains will affect how regions can resume normal life — ScienceDaily
As a new, apparently more transmissible version of the virus that causes COVID-19 has appeared in several countries, new research finds that the transmissibility of viral strains and the population density of a region will play big roles in how vaccination campaigns can help towns and cities return to more normal activities. The findings suggest […]
General anesthesia and normal sleep affect brain in an amazingly similar way as consciousness fades — ScienceDaily
What happens in the brain when our conscious awareness fades during general anesthesia and normal sleep? Finnish scientists studied this question with novel experimental designs and functional brain imaging. They succeeded in separating the specific changes related to consciousness from the more widespread overall effects, and discovered that the effects of anesthesia and sleep on […]
Why has our normal body temperature been dropping?
Feeling under the weather? Chances are you or your doctor will grab a thermometer, take your temperature and hope for the familiar 98.6 degrees Fahrenheit (37 degrees Celsius) everyone recognizes as “normal.” But what is normal and why does it matter? Despite the fixation on 98.6 F, clinicians recognize that there is no single universal […]
Children with asymptomatic brain bleeds as newborns show normal brain development at age 2 — ScienceDaily
In 2007, UNC researchers published unexpected and surprising results from a study based on magnetic resonance imaging (MRI) of newborn brains. Twenty-six percent of the newborns in the study were found to have asymptomatic subdural hemorrhages, or bleeding in and around the brain. It was an unexpected finding because subdural hemorrhage had been considered unusual […]
