​​Why Eyeballs Don’t Freeze At Subzero Temperatures?

If our hands, toes, noses, and other body parts are susceptible to freezing and getting frostbitten, it might seem unusual that our eyeballs can survive the cold totally unprotected. But, unlike other bodily extremities, the eyes are constantly pumped with a strong supply of warm blood—even in the coldest situations. Furthermore, our eyes are nestled rather deeply in our heads where bone, tissue, and fat also help keep them warm. Essentially, it’s virtually impossible for the eyes to freeze as long as they are inside a warm, functioning body.

Although it seems to defy logic that the wet, soft tissue of the eye wouldn’t immediately freeze when the thermometer drops below 32 degrees Fahrenheit, in truth, the explanation is quite simple. Our eyes don’t ice over because they are almost entirely encased in our warm, well-regulated heads. They are positioned more than halfway inside our noggins and protected by insulating bone, muscle, fat, and eyelids.

Making the eye even less likely to freeze is the fact that it’s filled with numerous blood vessels which continually heat it up with the hot blood from our bodies. In fact, the primary blood source to the eye is the ophthalmic artery, which is a branch off the same, deep artery that supplies the brain. When in cold surroundings, the body diverts even more blood to the brain (and other vital organs) which, in turn, helps keep eyes even warmer.

​​What is a Lazy Susan?

With a history that traces back as far as the 18th century, the Lazy Susan has stood the test of time, essentially unchanged. Also called a turntable, the Lazy Susan is a round or tray-shaped platform, that rotates on a set of bearings, and sits on a table or countertop to easily distribute food.

Thomas Jefferson invented the Lazy Susan in the 18th century, though they were referred to as dumbwaiters at that time. Lazy Susans are typically made of wood or plastic but glass, marble, stainless steel, and wire may also be used. Types of Lazy Susans include D-Shaped, Round, and Kidney-Shaped.

Often used in upper and lower cabinets, the Lazy Susan also creates accessibility for storage in the kitchen. With a simple spin, everything on the tray or shelf is within reach.

TSMC talks to Germany about potential new chip plant

Apple chip partner TSMC is seeking to set up a new plant in Germany, with the chip foundry in talks with the government to set up yet another production facility.
TSMC is known to be a highly in-demand chip producer, one that works on Apple Silicon and other Apple chips, as well as for other vendors. As part of a series of construction projects to expand capacity, it seems that there are plans to do so in Europe as well.
A senior executive of the chip maker told Bloomberg on Saturday that TSMC is talking to the German government about possibly setting up a plant in the country. Comments from TSMC SVP of Europe and Asia Sales, Lora Ho, indicate the talks are underway.
The discussions follow after TSMC Chairman Mark Liu advised to shareholders in June that it had started to assess the possibility of a new facility in Germany.
TSMC has yet to make a decision, but Ho says a number of factors can apply, including government subsidies, demand, and the local talent pool. However, Ho admitted TSMC hasn't talked to Germany about any potential incentives, nor where such a plant could be built.
The move is one of a number of construction projects TSMC has underway to build up its capacity around the world. This includes a $7 billion semiconductor factory in Japan, as well as a $12 billion facility in Arizona set to start mass production in early 2024.
The talks occur ahead of the introduction of the European Chips Act, a strategy from the European Union arriving in early 2022 to help boost semiconductor production.

​​What Happens When You Drink Too Much Water?

When you drink too much water, you may experience water poisoning, intoxication, or a disruption of brain function. This happens when there's too much water in the cells (including brain cells), causing them to swell. When the cells in the brain swell they cause pressure in the brain. You may start experiencing things like confusion, drowsiness, and headaches. If this pressure increases it could cause conditions like hypertension (High Blood Pressure) and bradycardia (Low Heart Rate).

Sodium is the electrolyte most affected by overhydration, leading to a condition called hyponatremia. Sodium is a crucial element that helps keep the balance of fluids in and out of cells. When its levels drop due to a high amount of water in the body, fluids get inside the cells. Then the cells swell, putting you at risk of having seizures, going into a coma, or even dying.
