1 in 12 doctors accepts payment from pharmaceutical companies related to opioids

A new study found that nearly one in five family medicine physicians accepted payments from pharmaceutical companies related to opioids, while anesthesiologists received the most total annual payments. The study suggests that pharmaceutical companies may have a stronger hold on how doctors prescribe opioids than previously known.

The color of people's clothing affects lizard escape behavior

A study found that western fence lizards preferentially flee from dark blue T-shirts over other colors, suggesting they respond to the color itself rather than its detectability. The researchers suggest that this could have implications for animal conservation and ecotourism, where human clothing color may affect animal behavior.

Landscapes give latitude to 2-D material designers

Rice University researchers have developed a method to control defects in 2-D materials, which can enhance their electronic, magnetic and optical properties. By growing atomic-thin sheets on curved substrates, they can manipulate the appearance of grain boundaries, which are critical in determining material behavior.
