Why do we get a runny nose after we Cry?

This runny nose is not mucus, but it actually is tears that came from your eyes.

Tears are produced by the lacrimal gland or commonly known as your tear gland located just above your eyes. Tears are important as a lubricant and to clean our eyes from particles in the air and are consistently produced by blinking our eyes. That is why when you feel your eyes are dry you are told to blink more. The tears are drained out to our noses through a lacrimal punctum. The lacrimal punctum is located in the inner corner of your eyes at both the upper and bottom eyelids. It is a small hole where your tears are drained to. In normal circumstances, the tears produced are very little and thus you may not notice it as it went into your nose. However, when you are crying you produced an excess of tears, and this tear goes into your nose mixed with the mucus that is already there and produces the snot which you usually have following a cry.

A blocked tear duct is a full or partial obstruction (blockage) in the nasal (nose) passageways that drain tears. If you have a blocked tear duct, your eyes may be itchy, irritated and watery. Another name for a blocked tear duct is nasolacrimal duct obstruction. Lacrimal refers to tears.

When a blocked tear duct doesn't open on its own, these techniques can help infants and adults:

Massage:

One of the easiest ways to fix a blockage in babies (or adults) is to massage the lacrimal sac -- the area where tears drain from the eye into the tear duct.

Antibiotics:

Your doctor may prescribe antibiotic eye drops or ointment.

Tear Duct Probing:

If your child's tear duct doesn't open on its own by age one, the doctor can do a procedure to remove the blockage.

For a few hours after tear duct probing, some children have blood-colored fluid drain from the eye.

Balloon Catheter Dilation:

If the blockage doesn't get better on its own or with probing, the doctor might try balloon catheter dilation.

Mechanical and optical mouse

How does the Mechanical Mouse work? A mechanical mouse consists of a heavy rubber ball whose movement makes the cursor move on the screen. Commonly known as the ‘rolling rubber ball’ mouse, it is considerably heavy, thanks to the rubber ball, a few wheels, and a number of other mechanical parts present inside it. When you move the mouse, the ball rolls beneath it, pushing the two plastic wheels/rollers linked to it in the process. One of those wheels detects side-to-side movement (x-axis wheel) and the other (y-axis wheel) detects movement in the up-and-down direction. Both of these wheels consist of spokes that ‘break’ a thin light beam inside the mouse. The number of times the beam breaks helps to calculate how far the mouse has moved. For instance, when you move the mouse straight up, the y-axis wheel turns. The farther up you go, the more the ball pushes the wheel and the more it breaks the light beam. This helps to determine how far the mouse has moved straight up....

How do Ants sense Food?

S ugar has a slight odor, particularly granulated beet sugar. While all species of ants can differentiate between a wide variety of odors, the smelling range differs from a few centimeters to meters. Desert ants can smell sugar from up to 3 meters. the food sources that ants cannot smell from a distance they 'smell' it (contact chemoreception) by touching it. So in a way, all the food they detect, they detect it by smelling. So yes, ants smell (although contact chemoreception is more like taste) the sugar. The ant colonies send scout ants to search for food in various directions, often up to a range of 100 to 200 meters.(Depends on the territorial boundary and time of the year). The scout marches steadily in less circuitous paths initially if it has memories of previous feeder locations. (Ants use visual landmarks, and a stereo-smell system to create an odor map and navigate) Periodically it will halt and look for olfactory cues. It will then take into a more circuitous rando...
