If you are a postgraduate researcher (PGR) like me, you will like this magazine. I liked the article about “a PhD window” and some good effects of running.
Read this magazine, it’s free :) (as if any PGR will buy it, if they will sell :)
Another interesting thing is that they have some tips for PG researchers sponsored by PGTips.
Interesting tricks to teach your body, ripped from here.
If your throat tickles, scratch your ear.
When you were 9, playing your armpit was a cool trick. Now, as an adult, you can still appreciate a good body-based feat, but you’re more discriminating. Take that tickle in your throat; it’s not worth gagging over. Here’s a better way to scratch your itch: “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.”
Feel no pain!
German researchers have discovered that coughing during an injection can lessen the pain of the needle stick. According to Taras Usichenko, author of a study on the phenomenon, the trick causes a sudden, temporary rise in pressure in the chest and spinal canal, inhibiting the pain-conducting structures of the spinal cord.
Stop the world from spinning!
One too many drinks left you dizzy? Put your hand on something stable. The part of your ear responsible for balance—the cupula—floats in a fluid of the same density as blood. “As alcohol dilutes blood in the cupula, the cupula becomes less dense and rises,” says Dr. Schaffer. This confuses your brain. The tactile input from a stable object gives the brain a second opinion, and you feel more in balance. Because the nerves in the hand are so sensitive, this works better than the conventional foot-on-the-floor wisdom.
Cure your toothache without opening your mouth!
Just rub ice on the back of your hand, on the V-shaped webbed area between your thumb and index finger. A Canadian study found that this technique reduces toothache pain by as much as 50 percent compared with using no ice. The nerve pathways at the base of that V stimulate an area of the brain that blocks pain signals from the face and hands.
Unstitch your side!
If you’re like most people, when you run, you exhale as your right foot hits the ground. This puts downward pressure on your liver (which lives on your right side), which then tugs at the diaphragm and creates a side stitch, according to The Doctors Book of Home Remedies for Men. The fix: Exhale as your left foot strikes the ground.
Thaw your brain!
Too much Chipwich too fast will freeze the brains of lesser men. As for you, press your tongue flat against the roof of your mouth, covering as much as you can. “Since the nerves in the roof of your mouth get extremely cold, your body thinks your brain is freezing, too,” says Abo. “In compensating, it overheats, causing an ice-cream headache.” The more pressure you apply to the roof of your mouth, the faster your headache will subside.
If you’re dying to retrieve that quarter from the bottom of the pool, take several short breaths first—essentially, hyperventilate. When you’re underwater, it’s not a lack of oxygen that makes you desperate for a breath; it’s the buildup of carbon dioxide, which makes your blood acidic, which signals your brain that somethin’ ain’t right. “When you hyperventilate, the influx of oxygen lowers blood acidity,” says Jonathan Armbruster, Ph.D., an associate professor of biology at Auburn University. “This tricks your brain into thinking it has more oxygen.” It’ll buy you up to 10 seconds.
The CIA had an opening for an assassin. After all of the background checks, interviews, and testing were done there were three finalists, two men and a woman.
For the final test, the CIA agents took one of the men to a large metal door and handed him a gun. “We must know that you will follow your instructions, no matter what the circumstances. Inside of this room, you will find your wife sitting in a chair. Kill her!!!” The man said, “You can’t be serious. I could never shoot my wife.”
The agent said, “Then you’re not the right man for this job.”
The second man was given the same instructions. He took the gun and went into the room. All was quiet for about five minutes. Then the man came out with tears in his eyes. “I tried, but I can’t kill my wife.”
The agent said, “You don’t have what it takes. Take your wife and go home.”
Finally, it was the woman’s turn. She was given the same instructions, to kill her husband. She took the gun and went into the room. Shots were heard, one shot after another. They heard screaming, crashing, banging on the walls.
After a few minutes, all was quiet. The door opened slowly and there stood the woman. She wiped the sweat from her brow and said, “You guys didn’t tell me the gun was loaded with blanks. I had to beat him to death with the chair.”
