How do we detect a high pitch sound source? “Mosquitone Detector” is a new sound measurement app that detects high-frequency noises and ultrasonic sounds hard to hear for human ears. It may have been exposed to artificial high-frequency noise while you do not notice. This app can detect and visualize such high-frequency noises.
Can great white sharks sense blood? Sharks can smell blood from hundreds of meters away—in concentrations as low as one part per million (ppm).
How far can great white sharks smell blood? Sharks can smell blood from up to around a quarter of a mile away. When you smell something in the air, it’s because scent molecules have dissolved into the wet lining of your nose. Smelling underwater is no different, except that the molecules are already dissolved in the seawater.

What receptors located in the retina detect color?
Cone cells, or cones, are photoreceptor cells in the retinas of vertebrate eyes including the human eye. They respond differently to light of different wavelengths, and are thus responsible for color vision, and function best in relatively bright light, as opposed to rod cells, which work better in dim light.
Can blood work from a physical detect cancer?
New research suggests that a routine blood test could help find cancers early. Researchers have previously shown that high levels of platelets – cells in the blood that help stop bleeding – can be a sign of cancer. But now they have found that even slightly raised levels of platelets may be an indication of cancer.
Can pap smear detect yeast infection?

When will a carbon dioxide detector detect carbon monoxide?
The CO alarm sounds if your sensor detects a buildup of carbon monoxide in your home—usually before you start sensing symptoms. With a low CO level (50 ppm), it may take up to eight hours for the alarm to go off. Higher levels (over 150 ppm) can trigger an alarm within minutes.

Can you see vasculitis on CT scan?

What can be mistaken for vasculitis?
4.1. Isolated Skin Vasculitis Mimics. Cutaneous manifestations of vasculitis include purpura, urticarial lesions, nodules, ulcers, livedo reticularis, and livedo racemosa [50]. Because the skin lesion is often nonspecific, a skin biopsy is usually required to prove or exclude vasculitis.
What are the receptors in the retina of the eye?
Two types of photoreceptors reside in the retina: cones and rods. The cones are responsible for daytime vision, while the rods respond under dark conditions. The cones come in three varieties: L, M, and S types (for long, middle, and short wavelength).
