The human immune system needs exposure to antigens (external organism that have entered the body) in order to function properly. The danger of using hand sanitizers excessively (especially in young children) is that the immune system does not get to experience as many antigens as it would without the use of sanitizer. A simple graphic illustrates how the ...

In almost every article I've read about the decision of the grand jury not to bring charges over the death of Eric Garner, it's taken for granted that the jury did see the video footage of his death. ...

“all our social policies are based on the fact that their intelligence is the same as ours – whereas all the testing says not really” can be parsed in two ways; as a question about the level of intelligence ie. how high IQ-score... or as a question about the type of intelligence ie. more a matter of skill. Most will probably think of it as a question about ...

NO MYSTERY AT ALL!!! It takes 30 years after starting to smoke to develop cancer, so it will take 30 years after a decrease in the percentage of people smoking for any change on the percentage of people getting lung cancer per year (assuming no other change in other factors such as level of pollution...).

Looks like a 10% decrease in incidence between 1990 and 2010. Suppose incidence lags smoking by 10 years. Then that matches the approximately 10% reduction in smoking between 1980 and 2000. Suppose incidence lags by 15 years. Then that isn't far off the 12% reduction between 1974 and 1990. Seems consistent to me. Also you are confusing rate of new cases ...

There is another case that might be confusing the issue here: Living organisms are sometimes carbon-dated and generally return non-current ages when this is done.

For circuitry to be able to detect something, that something has to be giving off some sort of energy such as radiation or an emission of a frequency, or has to be able to reflect some sort of energy back from the circuitry such as a pulse of light or sound wave. Even gas detectors including smoke alarms follow this principle as they work by monitoring the ...

Question: Can food type have any effect on weight loss even though net calories would remain constant? Answer: Yes. When you start a low-carb diet (for example < 50 g carbs/day), within the first 1-2 days, your body glycogen stores (about 500 grams) are depleted. Every gram of glycogen is bound to about 4 grams of water, so along with glycogen ...

Whether voting via the Internet could be made "secure" depends upon what is meant by the term.

The design of the symbol itself has been described in great detail, up to the color palette.[1] However, font designers have made it clear that they were going to design their own variants,[2] and they did[3], and I could find no records of any font designer having ever been sued over the (mis)representation of a currency symbol.

No and here is why. The conservation of mass has already been mentioned. Because we are dealing with chemical processes, mass-energy conversion is completely neglible. It means that if you put someone in a glass chamber, seal it (it's big enough, so no problem breathing) and measure the mass (normally only by weight, so no moving inside) it will always ...

According to common sense, the hair is a dead cell with no nerves. The brain / body couldn't possibly know whether the hair is there or not. Therefore, the body cannot respond to trimming because it can never know it occured. That is unless you pull the root of the hair, which isn't what happens when shaving. So the answer is no, hair growth cannot be ...

You can think of the seven colors as being nodes in the spectrum of visible light, those which are striking enough for human beings (at least English-speaking ones) to have assigned names. There are other colors, of course, even named ones, but those stand apart from the familiar named colors of the spectrum. The rest of the gradations are continuous tones ...
