Storing additional firearms securely does not necessarily negate the perceived risk of access if at least one gun remains unlocked.
Researchers found that male mosquito brains respond to a wider range of sounds than females and have more diverse responses. This suggests that males use complex acoustic cues to locate females in noisy environments, making traditional traps less effective.
A randomized controlled trial shows that eating more or less sweet-tasting foods didn't change how much people liked sweet flavors. The study found no association between the amount of sweet foods consumed and changes in body weight or biomarkers for diabetes and cardiovascular disease.
