An umbrella review of 25 reviews examining social media use and adolescent mental health. Most reviews characterized the associations as weak or inconsistent, while some reported more substantial negative associations.
Using fMRI, researchers examined how total sleep deprivation affected verbal learning, arithmetic, and divided attention. Brain activation changed differently depending on the cognitive task, suggesting the brain may recruit compensatory responses during sleep loss.
Researchers followed more than 114,000 U.S. adults for over three decades. Participants with the highest ultra-processed food consumption had a slightly higher risk of all-cause mortality, although associations differed substantially by type of ultra-processed food.
Researchers developed D-BIAS, an interactive system for detecting and reducing social bias in datasets using causal models and human input. Testing across three datasets found significant bias reductions with little data distortion and only a small loss in model utility.
During the July 2022 London heatwave, researchers estimated 370 deaths were attributable to heat, with about 38% of those heat-related deaths attributable to the urban heat island effect.
Researchers reviewed evidence from basic-income-style pilots in high-income countries. Studies involving unconditional payments generally reported improvements in mental wellbeing, including reduced stigma, greater hope for the future, and more time with family and friends.
