They see the human eye can not see!

An international science team, says rengeyiklerinin human eye can not detect the ultraviolet rays.

Rengeyiklerinin

living in the Arctic, unlike people, was his reaction to ultraviolet light.

Experts rengeyiklerinin polar environment, this ability can locate food more easily through the twilight of the long winter months and can see the remote thinks düşmanarını.

Ultraviolet rays, the wavelength range of light detected by the human eye, except for a short stay is located.

The researchers measured the response of the retina, giving anesthesia uyutulmuş rengeyiklerinin retinasına ultraviolet radiation.

The experiment, the light receptors in the retina of deer detected by ultraviolet rays existed.

Experts rengeyiklerinin the main food sources deer moss on the trees looked black and you think, because these so-called lichen algae species absorbs ultraviolet rays.

Likewise, it appears that wolves

rengeyiklerine people is expected to appear darker. Because the wolf with feathers can absorb the ultraviolet rays.

Snow white snow-covered environment, the objects appear to distinguish it from black people than the much easier to rengeyikleri.

Trace of urine in the snow

rengeyiğinin algıyabildiği easier with ultraviolet light, so deer around an enemy-thinking that maybe some other life-is said to be moving.

Researchers rengeyiklerinden after a similar attempt on the test seals. Ultraviolet rays is assumed to have the capacity to see the seals.

Professor Lars Chittka of the University of London Queen Mary

, bees can see ultraviolet rays also said,''In fact, humans and some mammals, the creatures have lost the ability to detect ultraviolet rays, may constitute an exceptional case.''He says.

Erases the bad memories of the first drug successful experiments!

Deletes bad memories of the first experiments in the success of drug memories sağladı.Kötü 'silebilen' reported that a drug is successful in the first experiments.

The drug is used for any other purpose by metyrapone

years, but now says is not produced. Once the drug is used in the treatment of hormone disorders, said lowering the level of chemicals in the brain related to memory.

Scientists from the University of Montreal in Canada, the drug during the past, hormone treatments to be effective, albeit less than on memory tests and then decided to obtain information. Experiments conducted on guinea pigs showed the drug can reduce the painful thoughts. This, contrary to the theory that the brain stored memories, is stated to be changed. Researcher Marie-France Marin, "Our findings offer the opportunity to delete many parts of the emotional memories can help people," he said.

Possible to delete the memory in a situation where

yaşanabilecekler, perhaps the most beautiful way, starring Jim Carrey and Kate Winslet, Eternal Sunshine of the Spotless Mind share the 2004 film (from scratch), his film had been told.

Quick walk against cancer

Research, men diagnosed with prostate cancer at least three hours a week walking motion is that revealed in half and spread of prostate cancer progression to be good for the treatment of advanced prostate cancer, said the march sürüyor.Hızlı.

According to the BBC, the U.S. conducted at the University of California San Francisco, age 60 of prostate cancer, yet has not begun to spread to 455 thousand men attended a research, at least three hours per week for men diagnosed with prostate cancer progression and spread of cancer is that the moving walk showed that half had downloaded.

Journal of Research on Cancer

not provide the same effect as slow walking arouses in drawing attention to the experts' findings, however, be interpreted with caution. Because most men walking at the same time the younger, or who are weak and non-smokers. This may explain some of the observed differences, "says noted.

Prostate Cancer Foundation president Dr.

research administration. To make sure that the results of research should be repeated, Helen Rippon'ın stated and lifestyle physical activity in men diagnosed with prostate cancer in the easiest way to achieve it, they advised them to walk the rest of it occurred.

Paracetamol risk of cancer

Paracetamol for pain relief and fever-reducing drugs active ingredient in the use of paracetamol in blood belirlendi.Düzenli cancer connection, can double the risk of developing cancer of the blood appeared.

American scientists, as a result of their research with an analgesic and antipyretic effect of paracetamol medications containing the active substance risk of developing cancer of the blood of persons over age 50, during a period of 10 years came from 1 percent to 2 percent was determined.

Fred Hutchinson Cancer Research Center in Seattle, experts from around Washington state, which initially healthy men and women, average age about 65 thousand were followed over a period of six years.

Research over 577 people in the so-called blood cancer lymphoma

seen. Experts on examining these 577 people, has discovered that people are using paracetamol on a regular basis.

Cutting 5 percent said that using paracetamol at least four times a week. Cutting 9 percent, that is, 52 individuals reported using drugs frequently.

The research

Emily White, "50 years old or older than ten years, this kind of a person's risk of developing cancer is 1 per cent. Paracetamol at least four years in our study at least four times a week has done to two per cent of risk taking reveal that, "he says.

Leukemia and Lymphoma Research

association, however, Dr David Grant, a numerical relationship, a causal link kanıtlamayacağını said, "saying that the well-known mechanism of paracetamol does not cause cancer. Elderly people over the years, the frequency of paracetamol use is not a reliable way to generate data to ask" he says. Than 1 percent to 2 percent increase in 10 years, argues that it is a small increase.

Early ejaculation drug therapy

City of Hamburg, Germany, to prevent premature ejaculation to deliver positive results from the studies of a new drug that holds başladı.Araştırmaları Flu Sexology.

Increase the duration of sexual intercourse and sexual intercourse should take an hour before entering the new drug will be released soon.

EARLY DRUG

discharged and our country, a large number of TEDAVİSİDünyada nightmare man's sexual life and transforming the language of medicine "Ejaculation praecox" called to tackle the problem of premature ejaculation on the work at least as old as the history of medicine.

Early ejaculation drug treatments, are given in support of sexual therapy. Groups of drugs used for this purpose is the following :1-Dopamine Antagonistleri2-Antidepresanlar3-Anksiyolitikler4-Local Drug creams or lotions: local drug reduced sensitivity of the tip of the penis.

One hundred percent effective drug thyme fly!

These flies do not harm people

medicine, chemical drugs that can substitute ... Mediterranean University who conducts research on insects for nearly 10 years at the Faculty of Arts and Sciences, Department of Biology Asst. Assoc. Dr. Huseyin Cetin, Pest organic to combat endemic in most of the Taurus Mountains close to 30 plants studied, he said.

Obtained findings "very encouraging,''he described the Cetin, killing and repellent effect on flies that garlic is described to detect. Strong resistance to research on flies, they observed a nearly 100 percent success in explaining Cetin, "Medical school faculty members receive a patent after investigating the impact on the people, we aim to fight haşerelerle vegetable,''he said. Cetin, flies on the lethal effect of garlic is said:

DEATH

80 percent "of our experiments, the thyme essential oils obtained from the flies, affects the respiratory system, or to increase the stopping of some enzyme systems and lead to the closure have determined that this means the entry of the respiratory system. Devices as adopted by the World Health Organization Olfaktometre our experiments, the flies are exposed to the smell of thyme found that 80 percent or higher mortality. In some experiments, resistance of less than 100 percent of the flies died .''

Can replace chemical pesticides, will increase in future years addressing the use of products derived from plants Cetin, the location of chemical drugs, more easily degradable in nature, said he would buy a nice smelling products.

Cetin, this kind of research indicating that it is important for the preservation of endemic species, "the world is being obtained from a number of drugs from plants. Turkey, these medications are usually imported from abroad. Plants collected in Turkey, as a medicine sold in our country. Weight given to these studies, the country needs to recover from dependence,''he said.

About 10 years, mosquitoes, black flies, and are doing research on that hamamböcekleriyle Cetin, research during the Antalya coastline cliffs, a small breeding ponds of sea water "is a genus of mosquito species Ochlerotatus''also said they have identified. Authorities, to avoid damage to the natural life falezlerdeki fight against this type of mosquito zorlandığına Huseyin Cetin striking, "the environment while trying to fight flies emanated chemical drugs, can harm other living creatures. If natural methods to combat, such as thyme, can be used in such cases,''he said.
