Researchers found that lower-paid Amazon Mechanical Turk microworkers — or Turkers — were more likely to reduce their efforts, as well as experience psychological states that could impact the results of the study. Microwork sites offer scientists and other researchers an inexpensive way to recruit participants, who often agree to be paid well below the minimum wage.

A computer model based on deep learning technology was able to better predict taxi demand in a city than current systems. This technology could help taxi companies and ride-sharing services, such as Uber, save money by better allocating vehicles and drivers. Fewer idling cars and less congested highways could lead to smarter cities that are safer and more sustainable.

Plant cell wall growth is typically described as a simple process, but researchers using a microscope that can create images on the nanoscale level have observed something more complex. Cell wall growth is a key factor in how plants grow and take shape.
