Spider silk sound system Researchers have investigated how spiders listen to their environments through webs and found that the webs match the acoustic particle velocity for a wide range of sound frequencies. Playing sound ranging from 1 Hz to 50 kHz for the spiders and measuring the spider silk motion with a laser vibrometer, they found the sound-induced velocity of the silk was the same as the particles in the air surrounding it. This confirmed the mechanism that these spiders use to detect their prey.

Patient satisfaction goes up. What's the matter with letting apps and AI run the ER? In ERs now, you'll get a tech-driven evaluation. But trading doctors' humanity and deductive powers for AI and apps has a high cost — dumbed-down medicine. Why docs shouldn’t do telehealth visits in the kitchen What's behind doctors in telehealth video visits can sway how patients feel about the care they receive, research finds. |
