Awesome discovery of the week: Glass melts when it gets too cold
Feb 23rd
Anyone who’s seen enough old Sesame Street episodes or been to enough Renaissance Fairs knows that when glass gets hot enough, it turns to liquid. Applied heat pumps energy into the solid pieces of glass, getting their molecules jiggling. As the heat dissipates, the glass becomes cool and solidifies again.p
Glass melts when it gets too cold
Most of the time, not many interesting things happen once a substance gets below the temperature required for solidification. Its atoms are bound to one another, and without the introduction of some kind of energy, they’ll stay that way. Glass, it turns out, is the exception. Once it gets close to absolute zero, it melts again.
But what could make that happen? The atoms in glass chilled to near-absolute zero have almost no energy, so they can’t be jiggling fast enough to tear apart from each other. And yet, on paper and in computer simulations, glass returned to a liquid form when brought close enough to absolute zero.
The wild card turned out to be quantum mechanics. Once the atoms of glass became still enough, they stopped acting like particles and instead acted like waves. The wave-like atoms now were able to flow, moving through spaces too small for particles to get through. This motion, and this ability to fit through small spaces, causes ultra-cold glass to melt into a liquid. No word yet if this works on the T-1000.
How to Have a Lucid Dream – Wake up in a Dream – Part I
Feb 20th
Lucid dreaming need not be elusive. Some simple techniques can make it possible for almost anyone.
Lucid dreaming
Lucid dreaming can be a very powerful experience for the dreamer. “You can be the absolute master of your dream world,” says MortalMist.com, a website and forum dedicated to lucid dreaming. “The very laws of nature can be bent and broken. No experience is beyond your reach, no feat too difficult or risky. If you can imagine it, you can make it happen.”
Many people report wonderful experiences in the dream worlds they’ve created. For some, though, lucid dreaming remains elusive. But there is good news; becoming skilled at “waking up” in a dream may be easier than it seems. There are several techniques that can be used to enter the world of lucid dreaming.
Lucid dreaming requires three things:
- the ability to recall dreams,
- a technique, known as a reality check, to become aware of dreaming, and
- strategies to remain in the dream.

Congenital Insensitivity To Pain – People Who Can’t Feel Pain – CIPA
Dec 14th
CIPA or congenital insensitivity to pain is one of the rarest diseases in the world. A very rare condition and it is also known as congenital analgia. People diagnosed with this condition have their pain sensors turned off and they can’t feel any pain. The condition is extremely dangerous as these people are prone to danger not knowing the level of pain inflicted.
Congenital Insensitivity To Pain – People Who Can’t Feel Pain
What caused the disorder? It is an unknown condition when the brain that recognizes the pain does not connect to the nerves that sense the pain. This unknown condition only happens to the pain sensors. People with CIPA have their other sensory areas completely checked and normal. Incredibly a rare disease, 35 people in the United States is diagnosed with CIPA. Sadly, people with CIPA has low survival rate and many doesn’t live that long to the age of 25 making the case a difficult case to study.
Pains are relatively a unique sense. It keeps us out of trouble, our body defense against harmful actions and not being able to feel pain is totally dangerous. Children especially will need to know how to sense this pain. We need to know what we should or shouldn’t do when we feel pain and we also know how not to cause pain to ourselves. Pain can help you to avoid danger and what causing this danger.
Anhidrosis, a condition of the body’s inability to sweat is found in people with CIPA. This condition can worsen the issue. With Anhidrosis, people with CIPA are not able to feel extreme temperature. Together with this and the body’s inability to sweat only means that their body is unable to regulate its temperature. More >
18 Health Tricks to Teach Your Body – Part I

Cure a Tickling Throat
Doctor Checking the Blood Pressure of a Patient
When you were 9, playing your armpit was a cool trick. Now, as an adult, you can still appreciate a good body-based feat, especially if it serves as a health remedy. Take that tickle in your throat: It’s not worth gagging over. Here’s a better way to scratch your itch: Scratch your ear. “When the nerves in the ear are stimulated, it creates a reflex in the throat that can cause a muscle spasm,” says Scott Schaffer, M.D., president of an ear, nose, and throat specialty center in Gibbsboro, New Jersey. “This spasm relieves the tickle.”
Experience Supersonic Hearing
If you’re stuck chatting up a mumbler at a cocktail party, lean in with your right ear. It’s better than your left at following the rapid rhythms of speech, according to researchers at the UCLA David Geffen School of Medicine. If, on the other hand, you’re trying to identify that song playing softly in the elevator, turn your left ear toward the sound. The left ear is better at picking up music tones.
Overcome Your Most Primal Urge
Need to pee? No bathroom nearby? Fantasize about Jessica Simpson. Thinking about sex preoccupies your brain, so you won’t feel as much discomfort, says Larry Lipshultz, M.D., chief of male reproductive medicine at the Baylor College of Medicine. For best results, try Simpson’s “These Boots Are Made for Walking” video. More >
Trichotillomania
Dec 10th
Trichotillomania is hair loss from compulsive pulling or twisting of the hair until it breaks off.
Trichotillomania
Causes
Trichotillomania is a type of compulsive behavior. Its causes are not clearly understood.
It may affect as much as 4% of the population. Women are four times more likely to be affected than men.
Symptoms
Symptoms usually begin before age 17. The hair may come out in round patches or across the scalp. The effect is an uneven appearance. The person may pluck other hairy areas, such as the eyebrows, eyelashes, or body hair.
These symptoms are usually seen in children:
- An uneven appearance to the hair
- Bare patches or all around (diffuse) loss of hair
- Bowel blockage (obstruction) if people eat the hair they pull out
- Constant tugging, pulling, or twisting of hair
- Denying the hair pulling
- Hair regrowth that feels like stubble in the bare spots
- Increasing sense of tension before the hair pulling
- Other self-injury behaviors
- Sense of relief, pleasure, or gratification after the hair pulling More >

Disease and Injury
Most of us will get injured or sick at some point in our lives. Here are some facts on how the human body reacts to the stresses and dangers from the outside world.

- Monday is the day of the week when the risk of heart attack is greatest. Yet another reason to loathe Mondays! A ten year study in Scotland found that 20% more people die of heart attacks on Mondays than any other day of the week. Researchers theorize that it’s a combination of too much fun over the weekend with the stress of going back to work that causes the increase.
- Humans can make do longer without food than sleep. While you might feel better prepared to stay up all night partying than to give up eating, that feeling will be relatively short lived. Provided there is water, the average human could survive a month to two months without food depending on their body fat and other factors. Sleep deprived people, however, start experiencing radical personality and psychological changes after only a few sleepless days. The longest recorded time anyone has ever gone without sleep is 11 days, at the end of which the experimenter was awake, but stumbled over words, hallucinated and frequently forgot what he was doing.

Spacetime invisibility cloaks can hide entire events inside temporal voids
Dec 9th
Invisibility cloaks are taking baby steps from science fiction to science fact. But there’s an even stranger and more incredible possibility – an invisibility cloak that works in both space and time, shielding whole events from history itself.

The basic idea is surprisingly simple. We see things because our eyes are able to interpret information from visible light. That light travels at, obviously enough, the speed of light, which means we see things once light has traveled from them to our eyes. Technically speaking, we never see anything the exact instant happens – there’s always a time lag between the object and when we see it.
This is fairly well-known for anyone with an interest in astronomy. The Moon is one light-second away, the Sun a little over eight light-minutes away, the nearest star 4.3 light-years away, the nearest galaxy , and so on. There are time lags on even everyday distances, however impossibly slight. For something a meter away, we see it as it was about 1/300,000,000th of a second ago.
Here’s how you use that information to build a spacetime cloak. All those times are for the speed of light in a vacuum, but light can slow down depending on what material it passes through. Researchers have slowed down light to as little as 38 miles per hour by sending it through a special, super-dense form of matter. And it’s through carefully slowing down and speeding up light that we can create a temporal void. More >

Aging and Death
From the very young to the very old, aging is a necessary and unavoidable part of life. Learn about the process with these interesting, if somewhat strange facts.

- The ashes of a cremated person average about 9 pounds. A big part of what gives the human body weight is the water trapped in our cells. Once cremated, that water and a majority of our tissues are destroyed, leaving little behind.
- Nails and hair do not continue to grow after we die. They do appear longer when we die, however, as the skin dehydrates and pulls back from the nail beds and scalp.
- By the age of 60, most people will have lost about half their taste buds. Perhaps you shouldn’t trust your grandma’s cooking as much as you do. Older individuals tend to lose their ability to taste, and many find that they need much more intense flavoring in order to be able to fully appreciate a dish.
- Your eyes are always the same size from birth but your nose and ears never stop growing. When babies look up at you with those big eyes, they’re the same size that they’ll be carrying around in their bodies for the rest of their lives. Their ears and nose, however, will grow throughout their lives and research has shown that growth peaks in seven year cycles. More >

Senses
The primary means by which we interact with the world around us is through our senses. Here are some interesting facts about these five sensory abilities.

- After eating too much, your hearing is less sharp. If you’re heading to a concert or a musical after a big meal you may be doing yourself a disservice. Try eating a smaller meal if you need to keep your hearing pitch perfect.
- About one third of the human race has 20-20 vision. Glasses and contact wearers are hardly alone in a world where two thirds of the population have less than perfect vision. The amount of people with perfect vision decreases further as they age.
- If saliva cannot dissolve something, you cannot taste it. In order for foods, or anything else, to have a taste, chemicals from the substance must be dissolved by saliva. If you don’t believe it, try drying off your tongue before tasting something.
- Women are born better smellers than men and remain better smellers over life. Studies have shown that women are more able to correctly pinpoint just what a smell is. Women were better able to identify citrus, vanilla, cinnamon and coffee smells. While women are overall better smellers, there is an unfortunate 2% of the population with no sense of smell at all.

Sex and Reproduction
As taboo as it may be in some places, sex is an important part of human life as a facet of relationships and the means to reproduce. Here are a few things you might not have known.

- On any given day, sexual intercourse takes place 120 million times on earth. Humans are a quickly proliferating species, and with about 4% of the world’s population having sex on any given day, it’s no wonder that birth rates continue to increase in many places all over the world.
- The largest cell in the human body is the female egg and the smallest is the male sperm. While you can’t see skin cells or muscle cells, the ovum is typically large enough to be seen with the naked eye with a diameter of about a millimeter. The sperm cell, on the other hand, is tiny, consisting of little more than nucleus.
- The three things pregnant women dream most of during their first trimester are frogs, worms and potted plants. Pregnancy hormones can cause mood swings, cravings and many other unexpected changes. Oddly enough, hormones can often affect the types of dreams women have and their vividness. The most common are these three types, but many women also dream of water, giving birth or even have violent or sexually charged dreams.
- Your teeth start growing 6 months before you are born. While few babies are born with teeth in place, the teeth that will eventually push through the gums of young children are formed long before the child even leaves the womb. At 9 to 12 weeks the fetus starts to form the teeth buds that will turn into baby teeth. More >
