A question asked by my son was, " Why is the moon sometimes orange? Or red? What causes this? " The orange and red tints that the Sun and Moon sometimes take on are caused by the particles in the Earth's atmosphere. When light (or more specifically, packets of light called photons) from an astronomical object passes through the Earth's atmosphere, it scatters off of particles in the latter. It turns out that these particles like to scatter blue light more than they do red light; so "bluer" photons (those with shorter wavelengths) tend to get scattered, and "redder" photons (those with longer wavelengths) pass through. So, astronomical objects look redder from Earth than they would from space, because the redder wavelengths from the objects penetrate the atmosphere better than the bluer
Google is a dangerous thing. It can lead you down a very scary road to a small padded cell if you're not careful. You know you've done it before. Something seems off. You don't feel well. And instead of making a doctor's appointment like any sane person would do, you run to your computer and Google something like. And BOOM! Up pops hundreds of thousands of search results. You skim past the rather benign ones, and zero in on the results that make your gut clench. It's scurvy! No, it's Lyme disease (never mind that you haven't been anywhere near a wooded area in 10 years)! Actually, if you're a wily veteran of all things Google searching, you know that plugging in any symptoms of any kind will always result in a diagnosis of cancer. But. I do wonder how many times Google has saved a life?
When your water has an onion odor, the cause can either be the water or another contributing factor. Before taking steps to stop the odor, you need to determine if the water is the actual problem or if the smell is being caused by something else. You can easily test if this is the problem by catching some of the water in a jar or glass and taking it outside. ...
The reason our brains have that wrinkly, walnut shape may be that the rapid growth of the brain s outer brain the gray matter is constrained by the white matter, a new study shows. Researchers found that the particular pattern of the ridges and crevices of the, which are called gyri and sulci, depends on two simple geometric parameters: the gray matter s growth rate and its thickness. The development of the brain s wrinkles can be mimicked in a lab using a double-layer gel, according to the study published today (Aug. 18) in the journal. The researchers noted that along with these physical constraints, genes also have a role in determining the brain s shape, because they regulate how neurons proliferate and migrate to their destinations. [ All mammalian species have similar layering in

Let s face it, we all get a little sweaty down there while working out. After all, it s the one thing you can t control when you re sweating away on the treadmill or in your favorite boot camp class. And engaging in a legs-together workout such as running tends to cause the most amount of sweat in your groin and vaginal area, so it s no wonder women experience this persistent problem.

According to the your skin has two main types of sweat glands: eccrine glands and apocrine glands. Eccrine glands appear over most of your body and open directly onto the surface of the skin. Apocrine glands, on the other hand, develop in areas abundant in hair
Could It Be PVCs? are another common cause of irregular heartbeat. PVC means the heartbeat that started in the two lower chambers of the organ (the ventricles) is beating before it should. You feel a regular beat, followed by an extra beat (the PVC), a pause, and then a stronger-than-usual beat. During the pause, the heart is filling with more than normal, which is why the next beat is extra-strong. It can happen in patterns or at random times. Call your doctor if this happens often or goes on for several minutes. What Else Should You Consider? Are you stressed? When you're in a stressful situation, your body releases the hormone adrenaline. That temporarily speeds up your heart rate and breathing, and raises your. If you're in the stressful situation for a long time, your heart may
Making a racket over toys isn t the only part of cat play with wild roots. If your cat deposits her toys in her food or water dishes, she s not bathing her toys, nor is she trying to nudge them to eat. Dr. Arnold Plotnick of CatChannel. com notes that putting nonfood items in food dishes is fairly common and suggests that its a cat s way of securing the toy in a safe place after playing with it. In your cat s world, her food and water dishes are part of her territory, a secure place for her to stash her valuables, much as if she were in the wild, hiding her prizes from potential predators. ...
Seizures while sleeping are actually pretty common - MANY dogs seize while sleeping. That in itself is not unusual. I know with my own dogs, the first seizure (of the usual cluster) starts 11pm to 3am - can't think of an exception right off hand. If the usual cluster follows, some are during daylight hours, but the dogs have been resting or sleeping generally. One of mine is under pretty good control and we can keep it at 1-3 seizures, the other guy is a toughie, and will have 4-7 no matter what (including sometimes when he's hospitalized). Often this means I'M tired as well, so I can't say that he may not have been standing up to start with, but I'm almost certain that he's sleeping or resting when he goes into another seizure. These guys are on KBr and phenobarbital, and do have much
