We propose the savanna theory of happiness, which suggests that it is not only the current consequences of a given situation but also its ancestral consequences that affect individuals’ life satisfaction and explains why such influences of ancestral consequences might interact with intelligence. We choose two varied factors that characterize basic differences between ancestral and… Continue reading Country roads, take me home… to my friends: How #intelligence, population density, and friendship affect modern #happiness

Functional genomics and metabolomics advance the ethnobotany of the #Samoan traditional medicine “matalafi”
Medicinal plants with extensive ethnobotanical histories, particularly those from Asia, have contributed to the approval of natural compounds as pharmaceutical drugs. In contrast, Samoan traditional medicine is relatively understudied. Working with traditional healers via an ethical, data sovereignty–driven collaboration led by indigenous Samoan researchers, we elucidate the chemical biology of the poorly understood but often-used… Continue reading Functional genomics and metabolomics advance the ethnobotany of the #Samoan traditional medicine “matalafi”
Association Between Genetic Risk for #Psychiatric Disorders and the Probability of Living in #Urban Settings
Urban residence has been highlighted as an environmental risk factor for schizophrenia and, to a lesser extent, several other psychiatric disorders. However, few studies have explored genetic effects on the choice of residence. Objective To investigate whether individuals with genetic predisposition to a range of psychiatric disorders have an increased likelihood to live in urban… Continue reading Association Between Genetic Risk for #Psychiatric Disorders and the Probability of Living in #Urban Settings
Waning Immunity after the BNT162b2 #Vaccine in Israel
In December 2020, Israel began a mass vaccination campaign against coronavirus disease 2019 (Covid-19) by administering the BNT162b2 vaccine, which led to a sharp curtailing of the outbreak. After a period with almost no cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, a resurgent Covid-19 outbreak began in mid-June 2021. Possible reasons for… Continue reading Waning Immunity after the BNT162b2 #Vaccine in Israel
Digging for data: How #sleep is losing out to roster design, sleep disorders, and lifestyle factors
Highlights•Shift start times <06:00, may result in sleep loss resulting in poor alertness. •Risk of sleep disorders increased with body mass and age. •Prevalence of shiftwork disorder and obstructive sleep apnea in mining is high. •Biomathematical modeling may be used to eliminate or reduce organizational risk. AbstractShift workers employed at a remote mining operation may… Continue reading Digging for data: How #sleep is losing out to roster design, sleep disorders, and lifestyle factors
Study: People Are Getting #Dumber
IQ scores have been steadily falling for decades, but genes aren't to blame – their environment is at fault. New research published this week in Proceedings of the National Academy of the Sciences of the United States of America examined the IQ scores of men born between 1962 and 1991. Researchers found that scores increased… Continue reading Study: People Are Getting #Dumber
#Environmental risk factors and #cardiovascular diseases: a comprehensive expert review
AbstractNon-communicable diseases (NCDs) are fatal for more than 38 million people each year and are thus the main contributors to the global burden of disease accounting for 70% of mortality. The majority of these deaths are caused by cardiovascular disease (CVD). The risk of NCDs is strongly associated with exposure to environmental stressors such as… Continue reading #Environmental risk factors and #cardiovascular diseases: a comprehensive expert review
#Heat stress and PPE during #COVID-19: impact on healthcare workers’ performance, safety and well-being in NHS settings
Personal protective equipment (PPE) can potentiate heat stress, which may have a negative impact on the wearer's performance, safety and well-being. In view of this, a survey was distributed to healthcare workers (HCWs) required to wear PPE during the coronavirus disease 2019 pandemic in the UK to evaluate perceived levels of heat stress and its… Continue reading #Heat stress and PPE during #COVID-19: impact on healthcare workers’ performance, safety and well-being in NHS settings
Transmission of community- and hospital-acquired #SARS-CoV-2 in hospital settings in the UK: A cohort study
Nosocomial spread of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has been widely reported, but the transmission pathways among patients and healthcare workers (HCWs) are unclear. Identifying the risk factors and drivers for these nosocomial transmissions is critical for infection prevention and control interventions. The main aim of our study was to quantify the relative… Continue reading Transmission of community- and hospital-acquired #SARS-CoV-2 in hospital settings in the UK: A cohort study
