The human nose can smell fatty foods

Image
American researchers have found that each person has a nose specific detector fat. With it, we can determine the level of this substance in different products. Scientists at the California Science Center have found another way to avoid overeating, which can be used along with counting calories and a careful selection of products. It turns out that the person in the nose has its own excellent for detection of fat smell given to us by nature. Researchers believe that people can easily incorporate this detector for the regulation of its power. Scientists believed that the smell of food is almost always determined by the man before he eats anything. It turned out that one of the first components of this odor is received by us olfactory information about whether the food contains fat. And if using innovative technologies, food producers will smell of fat in food more perceptible for the health of society, it will lead to a significant roll in the general trend of development of a worl...

Scientists have learned the value of nightmares

Scientists believe that bad dreams help psyche to cope with negative emotions, while nightmares indicate that processing has failed. As you know, we sleep about a third of his life, that is more than twenty years. 5 years of the twenty we dream. And there, you see, sometimes things happen much more interesting than real life. People have long tried to unravel the purpose of bad dreams. The latest research in the field of psychology and physiology of the brain helped to open the door a little to the mysterious world of dreams. Scientists believe that bad dreams help psyche to cope with negative emotions, while nightmares indicate that processing has failed. In the journal Current Directions in Psychological Science , scientists Ross Levin and Tore Nielsen wrote that terrible dreams - one of the methods that the brain uses to process negative emotions. Emotional regulation may be the main purpose of sleep, which occurs in the majority of dreams. Nightmares, which scientist...

Sleep naked - Scientists have come to an Interesting Conclusion

That sleeping naked is very good for human health, not only physical but also psychological. Sleep in the nude, allows the human body to prevent overheating of the body, as the overheating of the body could interfere with production of important hormones such as melatonin and growth hormone. In addition, the normal body temperature allows the body to restore the skin. In addition, sleeping naked can control hunger, also lowers the blood levels of the hormone cortisol (stress hormone). This allows the person to wake up in the morning refreshed, with a good mood and keep this state throughout the day. A man who had trouble sleeping or body was overheated in the morning eat a lot more of its rules, rather than the one who is sleeping naked. The scientists were able to prove that the most beneficial sleep is sleep duration of 7 hours, and the best position to sleep position is the embryo or supine. In addition, they were able to reaffirm that daytime sleep is beneficial for the b...

Therapy for smoking kills the pleasure of nicotine

Can't kick cigarettes? A vaccine may one day help by preventing nicotine from reaching its target in the brain, according to research published this week. Most smoking therapies do a poor job of stopping the habit 70% to 80% of smokers who use an approved drug therapy to quit relapse. Scientists say this is because the targets of existing therapies are imperfect, only slightly weakening nicotine's ability to find its target in the brain. So some scientists have been trying a different approach creation of a vaccine. It would work like this: People would inject the vaccine like a shot, and the vaccine would create nicotine antibodies, molecules that can snatch up nicotine from the bloodstream before it reaches the brain. The vaccine could be used by smokers who want to quit or people who are worried about getting addicted to cigarettes in the future. Researchers have tried to create vaccines in the past, but the ones they've come up with have not been particularly effe...
