Many people choose unemployment benefits over poorly paid jobs

A Norwegian University of Science and Technology study published in PLOS One found that extremely low minimum wages and unemployment benefits can discourage people from working. The 'work incentive principle' aims to create a financial advantage for working over receiving benefits, but when both are very low, it loses its effectiveness.

What a bumble bee chooses to eat may not match ideal diet

A new study led by Penn State researchers suggests that bumble bees' dietary preferences do not necessarily reflect their optimal nutritional needs. Despite choosing diets high in certain nutrients, the bees experienced negative fitness outcomes, including decreased egg-laying and unchanged body mass.

Understanding the role of pigmentation in hereditary hearing loss

A study published in Neurobiology of Disease found that melanin degradation is impaired in genetically engineered mice lacking the SLC26A4 gene, leading to chronic inflammation and macrophage activation. The researchers propose a novel pathological cascade where melanin accumulation exacerbates hearing loss in pigmented individuals.

HKU research reveals “Anxious Monday” effect: chronic stress hormone surge linked to start of week in older adults

A study by the University of Hong Kong found that Mondays uniquely drive long-term biological stress in older adults, with a significant increase in stress hormone levels up to two months later. The 'Anxious Monday' effect is linked to dysregulation of the body's stress response system and has implications for heart health.
