Study on dogs paws

Japanese researchers have managed to resolve an issue that has long concerned the zoologists in several countries: namely, how dogs sit on ice for extended periods of time without their feet and toes freeze.

Researchers Yamazaki Gakuen University in Tokyo have discovered that dogs feet and toes are provided with a network of glands that removes a very high fat secretion, preventing frostbite.

If people are exposed to very cold, vasoconstriction of blood vessels in the extremities of the body reduces the blood flow in those areas.

The team led by Dr. Hiroyoshi Ninomya used a scanner attached to an electron microscope study of 4 dogs mature feet. Scientists have discovered that the arteries that send blood to the feet of dogs are coupled with a network of small veins, the whole system acting as a heat exchanger., Serving to cool heat coming from the feet before sending back the body.

Destruction of bacteria proteins tears

A new study by researchers at the University of Irvine, California tried to discover how a protein localized in human tears and involved in immune defense can kill bacteria.

Researchers believe that this study may be crucial for long-term activity designed to diagnose cancer in its early stages.
Even a century ago, when Alexander Fleming, Nobel laureate, discovered that human tears contain proteins called lysozyme antiseptic, scientists tried to find out if they could neutralize bigger and more virulent bacteria.
It was found that lysozyme molecules have a kind of "Jaws" that catch and chew rows of cells in a similar way a man eats a corn. Through this process, the protein walls destroys bacteria trying to enter the eye and infect them.

Drug against unpleasant memories

In a famous movie, "Eternal Sunshine of the Spotless Mind" (Eternal Sunshine of the Spotless Mind), a man and a woman were submitted for erasing unpleasant memories of their relationship. The idea could soon become reality.

Scientists announce that there will be no more than 10 years on the market a miracle pill that will help us get rid of unpleasant memories.
Thus, the traumatic events that will live remains a vague memory, removed.
The product will especially address those fears and those who have experienced trauma such as a car accident.
The announcement comes after more research specialists conducted at Leicester University, after which they learned how the brain behaves in stressful situations.

Tomatoes, other than we know we

Horticultorii Israelis have created a kind of tomato red interior, but with very dark skin color, which darkens as tomatoes ripen in the sun.
The researchers crossed wild varieties cultivated varieties of tomato, resulting in a new variety with striking aspect in color almost black fruit (botanically speaking, what we call "red" are fruits of the plant).

Variety of "black red" was called Black Galaxy. Dark pigment - which is akin to that of blueberries - is photosensitive, so color is even darker as the tomato haulm left more on the sun.
The antioxidant properties of red tomatoes have all the usual varieties, scientists believe it could be even richer in antioxidants and vitamin C, found in high concentrations in the dark pigment.
Producing company, Technological Seeds will present its new creation an exhibition specialized R & D Arava Agricultural Exhibition, and Galaxy Black tomatoes could enter the market next year.

O pill that can speed bone healing

A revolutionary material created by U.S. researchers, could accelerate fracture healing, shorten the process from several months to several days.
Scientists at the University of Georgia, USA, used celuele stem to produce a protein involved in bone regeneration.

They incirporat prioteina in a gel, obtaining a material which they named "clay fracture" and have tested on laboratory rats, stabilizing fractures and introducing a small amount of material at fracture.
After two weeks, the animals could use their feet without any problem.
Currently, "plasticine fracture" is tested on larger animals such as pigs and sheep.

Positive people can do much more than we thought

A new study by Swiss researchers demonstrated in a practical and effective power of positive thinking. According to the results, subjects who claimed and were convinced that they feel good, are healthy and everything going for them finally enjoyed a longer life and better health than pessimistic people.

The researchers took into account risk factors that affect life expectancy such as smoking, alcoholism, chronic diseases and hypertension. 7 During the decade of the century, a sample of 8,000 people has undergone positive thinking experiment.
Thirty years later, the volunteers were diagnosed again and surprised the researchers found that people who think positively about their general health status have lived longer than pessimistic.

"Our study demonstrates once again that people who are viewed as having excellent health come to live longer than others. Decisive factors in this process include a positive attitude, an optimistic estimate of the surrounding reality and a state of complacency about personal life, "said David Fah, researcher at the University of Zurich.
According to data submitted at the end of the study, men who believed that their health is mainly negative, were 3.3 times less likely to survive than those who maintain that they enjoyed good health. For women, those with negative thinking had a 1.9 times higher risk of dying than those who rank themselves positively.
Despite these results, some experts are not convinced of the power of positive thinking for long-term health maintenance.
