Vaccine hesitancy predicts future COVID-19 vaccine side effects
The precise relationship between vaccine hesitancy and COVID-19 vaccination side effects has not previously been explored in vaccinated persons. A fundamental question arises in regard to the directionality of this vaccine hesitancy-vaccine side effect link, namely which variable predicts which. One possibility is that side effects from an earlier dose predict one’s vaccine hesitancy towards a later dose. Alternatively, one’s psychological negativity (hesitancy) towards an earlier dose could predict subsequent side effects from a later vaccination dose. The latter direction reflects a Nocebo effect, i.e., side effects driven by psychological factors rather than by an active treatment component. Results showed only the latter direction to be true. Namely, only earlier vaccine hesitancy towards the second COVID-19 dose predicted subsequent nocebo side-effects following the booster vaccination. To put this in perspective up to 16% of one’s vaccine side effects were explained by earlier va

Whole Ecosystem Warming Stimulates Methane Production from Plant Metabolites in Peatlands
While peatlands have historically stored massive amounts of soil carbon, warming is expected to enhance decomposition, leading to a positive climate change feedback effect. This study experimentally warmed peatlands in northern Minnesota and observed increased methane production relative to carbon dioxide release. This methane release process is likely to amplify global climate warming.

Scientists Measure Calcium Nuclei’s Thin Skin
Scientists measuring the nucleus of calcium-48 to determine how its 20 protons and 28 neutrons are distributed inside its nucleus found that the protons and neutrons aren’t simply sprinkled throughout the nucleus. Instead, they form a neutron-rich “thin skin” around a core of evenly distributed protons and neutrons. This skin is thinner than many theoretical models predicted and not consistent with expectations based on recent observations of lead’s thick skin.
