A new study examined how humans perceive different types of deception by robots, revealing that people accept some lies more than others. Researchers presented nearly 500 participants with scenarios where robots engaged in external, hidden, and superficial deceptions in medical, cleaning, and retail settings. Participants disapproved most of hidden deceptions, such as a cleaning robot secretly filming, while external lies, like sparing a patient from emotional pain, were viewed more favorably.

A recent study has found a positive correlation between nighttime light pollution and the prevalence of Alzheimer’s disease (AD) in the United States. Researchers discovered that higher levels of light at night are associated with increased AD rates, particularly among individuals under the age of 65.
