Understanding others: By age three, we can do this with mirror neurons

Researchers discovered that children's understanding of others' motor intentions develops with age, but is already present at three years old. They measured the activation of a muscle involved in opening the mouth while performing tasks, finding that it activated earlier in older children.

Roles of PEDF in exercise-induced suppression of senescence and its impact on lung pathology in mice

The study found that exercise increased PEDF levels in skeletal muscles and suppressed senescence markers in the lungs. PEDF also reduced senescence markers in multiple tissues and attenuated decline in respiratory function in pulmonary emphysema mouse model, suggesting its potential as a therapeutic agent for age-related diseases.

Decline in global adolescent fertility rates is counteracted by increasing teen births in Sub-Saharan Africa

A new report highlights a troubling trend: while global adolescent fertility rates have significantly declined, sub-Saharan Africa is experiencing an increase in teen births. The region's share of global adolescent births surged from 12% in 1950 to 47% in 2020 and is projected to reach a majority by 2035.

Supplements slow disease progression during late stage of “dry” age-related macular degeneration

Researchers found that taking AREDS2 supplements slows the expansion of geographic atrophy regions towards the central foveal region of the retina. The study suggests that antioxidant supplementation may slow central vision loss in people with late-stage dry AMD, supporting continued use of AREDS2 supplements.

Social media polls deliberately skew political realities of 2016, 2020 US presidential elections, finds research team led by UMass Amherst

Research by the University of Massachusetts Amherst team found that social media polls consistently predicted a landslide election win for Trump in both 2016 and 2020 presidential contests. The polls were predominantly crafted by males with a bias for Trump, and purchasing votes from troll farms was common.
