“Shika Sonic” device installed near a school in Nanto City, Toyama Prefecture no bear sightings for two and a half months — mayor calls it “a major success”

The Shika Sonic device, developed to deter wild animals like bears and deer, was installed near a school in Nanto City, Toyama Prefecture. Since its installation, there have been zero bear sightings in the surrounding area. The city is now considering expanding the use of the device to tourist areas based on promising results.

Study reveals insights into long COVID trajectories in adults

Researchers identified eight different long COVID trajectories, depending on severity and duration of symptoms, in a study of over 3,500 adult participants. The study found that 10.3% of patients had long COVID symptoms three months after infection, with 81% continuing to experience persistent or intermittent symptoms a year later.
