People track when talkers say ‘uh’ to predict what comes next — ScienceDaily

Spontaneous conversation is riddled with disfluencies such as pauses and ‘uhm’s: on average people produce 6 disfluencies every 100 words. But disfluencies do not occur randomly. Instead, ‘uh’ typically occurs before ‘hard-to-name’ low-frequency words (‘uh… automobile’). Previous experiments led by Hans Rutger Bosker from the Max Planck Institute for Psycholinguistics have shown that people can…

Over a 5-year period, most guns found in states with strict gun laws were obtained from less restrictive states — ScienceDaily

Gun-related homicide rates in states with strict gun laws increase when neighboring states have less restrictive laws as a result of gun trafficking across state lines, suggests a new study from Penn Medicine. A review of gun tracing data also revealed that 65 percent of the guns recovered in the most restrictive states originated from…

Antibiotic resistance is spreading from wastewater treatment plants — ScienceDaily

The products of wastewater treatment have been found to contain trace amounts of antibiotic resistant DNA. These products are often reintroduced to the environment and water supply, potentially resulting in the spread of antibiotic resistance. As such, researchers at the University of Southern California Viterbi School of Engineering have been studying the development of these…
