There’s not much we could do without our muscles — swallow, breathe, move at all. Yet despite how essential muscles are to our survival, there’s still a lot we don’t know about them and how they work. Here are six fun facts you may not have known about your muscles.
There isn’t just ONE strongest muscle in your body.
You’ve probably heard that your tongue is the strongest muscle, and while it is certainly impressive — with its “combination of elasticity and forcefulness” — LiveScience explains that there are too many different ways to measure strength to crown any one muscle strongest. The calf muscle, for example, is actually the muscle that exerts the most force, while the jaw muscle exerts the most pressure. And the gluteus maximus is the biggest muscle in the human body.
Muscles grow while you sleep.
All that work you put in at the gym pays off after you hit the hay. In the deep and restorative stages of sleep, the muscles relax and blood flow to the muscles increase. Hormones that fuel muscle development are released and tissues grow and repair, according to the National Sleep Foundation. Without enough deep sleep, don’t expect to see results at the gym.
Muscles make 85 percent of your body heat.

Take a moment to think about the last time you memorized someone’s phone number. Was it way back when, perhaps circa 2001? And when was the last time you were at a dinner party or having a conversation with friends, when you whipped out your smartphone to Google the answer to someone’s question? Probably last week.
Technology changes the way we live our daily lives, the way we learn, and the way we use our faculties of attention — and a growing body of research has suggested that it may have profound effects on our memories (particularly the short-term, or working, memory), altering and in some cases impairing its function.
The implications of a poor working memory on our brain functioning and overall intelligence levels are difficult to over-estimate.
“The depth of our intelligence hinges on our ability to transfer information from working memory, the scratch pad of consciousness, to long-term memory, the mind’s filing system,” Nicholas Carr, author of The Shallows: What The Internet Is Doing To Our Brains, wrote in Wired in 2010. “When facts and experiences enter our long-term memory, we are able to weave them into the complex ideas that give richness to our thought.”
While our long-term memory has a nearly unlimited capacity, the short-term memory has more limited storage, and that storage is very fragile. “A break in our attention can sweep its contents from our mind,” Carr explains.
Meanwhile, new research has found that taking photos — an increasingly ubiquitous practice in our smartphone-obsessed culture — actually hinders our ability to remember that which we’re capturing on camera.
Concerned about premature memory loss? You probably should be. Here are five things you should know about the way technology is affecting your memory.
Information overload makes it harder to retain information.
Even a single session of Internet usage can make it more difficult to file away information in your memory, says Erik Fransén, computer science professor at Sweden’s KTH Royal Institute of Technology. And according to Tony Schwartz, productivity expert and author of The Way We’re Working Isn’t Working, most of us aren’t able to effectively manage the overload of information we’re constantly bombarded with.
When the working memory is experiencing digital overload, it’s like a glass of water overflowing. Schwartz explained in an interview with The Huffington Post in June:
“It’s like having water poured into a glass continuously all day long, so whatever was there at the top has to spill out as the new water comes down. We’re constantly losing the information that’s just come in — we’re constantly replacing it, and there’s no place to hold what you’ve already gotten. It makes for a very superficial experience; you’ve only got whatever’s in your mind at the moment. And it’s hard for people to metabolize and make sense of the information because there’s so much coming at them and they’re so drawn to it. You end up feeling overwhelmed because what you have is an endless amount of facts without a way of connecting them into a meaningful story.”
The Internet is becoming the brain’s “external hard drive.”
Research has found that when we know a digital device or tool will remember a piece of information for us, we’re less likely to remember it ourselves. A recent Scientific American article likened the Internet to the brain’s “external hard drive,” explaining that the social aspect of remembering has been replaced by new digital tools.

Bell’s palsy, or idiopathic facial paralysis, is a form of facial paralysis resulting from dysfunction cranial nerve VII (the facial nerve) that results in the inability to control facial muscles on the affected side. Several conditions can cause facial paralysis, e.g., brain tumor, stroke, and Lyme disease. However, if no specific cause can be identified, the condition is known as Bell’s palsy. Named after Scottish anatomist Charles Bell, who first described it. Bell’s palsy is the most common acutemononeuropathy (disease involving only one nerve) and is the most common cause of acute facial nerve paralysis.
Bell’s palsy is defined as an idiopathic unilateral facial nerve paralysis, usually self-limiting. The hallmark of this condition is a rapid onset of partial or complete palsy that often occurs overnight. In rare cases (1%), it can occur bilaterally resulting in total facial paralysis.
It is thought that an inflammatory condition leads to swelling of the facial nerve. The nerve travels through the skull in a narrow bone canal beneath the ear. Nerve swelling and compression in the narrow bone canal are thought to lead to nerve inhibition, damage or death. No readily identifiable cause for Bell’s palsy has been found.
Corticosteroids have been found to improve outcomes while anti-viral drugs have not. Early treatment is necessary for steroids to be effective. Most people recover spontaneously and achieve near-normal to normal functions. Many show signs of improvement as early as 10 days after the onset, even without treatment.
Often the eye in the affected side cannot be closed. The eye must be protected from drying up, or the cornea may be permanently damaged resulting in impaired vision. Causes, incidence, and risk factors
Bell’s palsy affects about 30,000 – 40,000 people a year in the United States.
Bell’s palsy involves damage to the seventh cranial (facial) nerve. This nerve controls the movement of the muscles of the face.
Bell’s palsy is thought to be due to swelling (inflammation) of this nerve in the area where it travels through the bones of the skull.
The cause is often not clear. A type of herpes infection called herpes zoster might be involved. Other conditions that may cause Bell’s palsy include:
? HIV infection
? Lyme disease
? Middle ear infection
Sometimes you may have a cold shortly before the symptoms of Bell’s palsy begin.
Symptoms most often start suddenly, but may take 2 – 3 days to show up. They do not become more severe after that. Sudden weakness or paralysis on one side of the face that causes it to droop.
Symptoms are almost always on one side only. They may range from mild to severe.
The face will feel stiff or pulled to one side, and may look different. Other symptoms can include:
? Difficulty eating and drinking; food falls out of one side of the mouth
? Drooling due to lack of control over the muscles of the face
? Drooping of the face, such as the eyelid or corner of the mouth
? Hard to close one eye
? Problems smiling, grimacing, or making facial expressions
? Twitching or weakness of the muscles in the face
Other symptoms that may occur:
? Dry eye or mouth
? Loss of sense of taste
? Sound that is louder in one ear (hyperacusis)
? Twitching in face
Often, no treatment is needed. Symptoms often begin to improve right away. However, it may take weeks or even months for the muscles to get stronger, and this may be frustrating.
Your health care provider may give you lubricating eye drops or eye ointments to keep the surface of the eye moist if you cannot close it completely. You may need to wear an eye patch while you sleep.
Sometimes medicines may be used, but it is not clear how much they help. If medicines are used, they should be started right away.
• Corticosteroids may reduce swelling around the facial nerve
• Medications can fight the virus that may be causing Bell’s palsy
Surgery to relieve pressure on the nerve (decompression surgery) is controversial and has not been shown to routinely benefit people with Bell’s palsy.
The goal of the treatment is to eliminate the source of the nerve damage. Patients with less nerve damage have better chances of recovery.
Medications are often used as part of the treatment:
• If infection is the cause, then an antibiotic to fight bacteria (as in middle ear infections) or antiviral agents (to fight syndromes caused by viruses like Ramsay Hunt) may be used.
• If swelling is believed to be responsible for the facial nerve disorder, steroids are often prescribed.
• In certain circumstances, surgical removal of the bone around the nerve (decompression surgery) may be appropriate.
Physiotherapy can be beneficial to some individuals with Bell’s palsy as it helps to maintain muscle tone of the affected facial muscles and stimulate the facial nerve. It is important that muscle re-education exercises and soft tissue techniques be implemented prior to recovery in order to help prevent permanent contractures of the paralyzed facial muscles. Muscle re-education exercises are also useful in restoring normal movement. To reduce pain, heat can be applied to the affected side of the face. In individuals with unresolved facial nerve paralysis, transcutaneous electrical stimulation can be an effective treatment strategy(TENS).
• Exercise the facial muscles in front of a mirror.
• Massage the face.
• Apply gentle heat to reduce pain.
• Using a finger, regularly close the eye to keep it moist.
• Tape the eye closed for sleeping.
• Use protective glasses or clear eye patches to keep the eye moist and to keep foreign materials
from entering the eye.
• Use doctor-recommended artificial tears or an ointment to keep the eye moist.

Cerebal Palsy is an umbrella term encompassing a group of non-progressive, non-contagious motor conditions that cause physical disability in human development, chiefly in the various areas of body movement – Wikipedia
At some point very early in life, either while a baby is still growing in the womb, during birth or shortly after, something happens to interfere with the normal development of the brain or to injure the brain tissues. This abnormal development or injury disrupts the nerve signals between the brain and the muscles, leading to problems with movement, posture and coordination as the child grows up. While some people are severely affected, others have only minor disruption, depending on which parts of the brain are not functioning properly. It’s estimated that as many as 1 in every 400 children may have cerebral palsy. – BBC Health

If you’re feeling completely confused about whether you should cut fat from your diet, you are not alone. But here’s the bottom line: fat does not make you fat or sick. So, why do so many people believe that fat is bad for you and causes heart attacks?
This all started in the Dr. Key’s Seven Countries Study decades ago that examined heart risk based on lifestyle and dietary habits. He found that in the countries where people ate more fat—especially saturated fat—there were more cases of heart disease, and he concluded that the fat caused the disease. But here’s the problem with this study: correlation is not causation. Just because both fat intake and heart disease were higher among the same population doesn’t mean the heart disease was caused by the fat consumption. Here’s another way to look at it: Every day, you wake up and the sun comes up, but although these events happen at the same time, you waking up doesn’t cause the sun to come up.
A study that observed this would show a 100% correlation between these two events, but it would be wrong to conclude that you caused the sun to rise. Because of studies like this, we became sidetracked into believing that saturated fat causes heart disease. But in fact, we are now learning that sugar is the true culprit, not fat. A review of all the research on saturated fat published in the American Journal of Clinical Nutrition found there was no correlation between saturated fat and heart disease. And a recent editorial in the British Journal of Medicine hammers home the same point and shatters the myth that fat causes obesity and heart disease. Researchers have found that, while it’s true that lowering saturated fat in the diet may lower total cholesterol, it’s actually lowering the good kind of cholesterol, the light, fluffy, buoyant LDL that’s not a problem.
When people eat less fat, they tend to eat more starch or sugar instead, and this actually increases their levels of dangerous cholesterol, the small, dense cholesterol that causes heart attacks. In fact, studies show that 75% of people who end up in the emergency room with a heart attack have normal overall cholesterol levels. What they do have is pre-diabetes or type 2 diabetes.

Nowadays, ONE IN EVERY TWO people in Japan develops cancer.
Behind the statistic is a surprising fact. Humans became prone to cancer because they evolved. That’s what the latest research has uncovered.
In Japan, cancer is now the number one cause of death.
How should we humans deal with cancer? Advanced scientific research is approaching the disease from an evolutionary perspective in an attempt to find the answer.

Depression causes people to feel sad or down for a long period of time. More than 350 million people suffer from this disease worldwide. Depression was once considered an illness of the mind. But doctors have found physical abnormalities in the brains of people being treated for depression. Now scientists are coming up with a range of treatments, including one that directly controls brain function. How can we overcome depression? We’ll look into the origins of this all-too-common disease.

Pitfalls of State-of-the-Art Pump -
Every year, over 7 million people die from heart disease worldwide. It’s the number-one cause of death for human beings. Human ancestors gained a high-performance heart. But as they evolved, they put a bigger burden on the organ, forcing themselves to live with a higher risk of disease. Heart disease is an evolutionary fate for humans. We’ll look at its origins and recent research that aims to find a cure.
