Optimism increases life .. This is the latest and most important scientific and technological news this week
Between the introduction of the technology to recognize the passengers from their faces, the detection of the death of 100 million trees due to the drought in California, USA, and put the giraffes for the first time on the list of extinction; here is a list of the most important discoveries and scientific and technological news reached by scientists this week.

1 – smile .. will not die soon
A new study published by scientists in the American Journal of Immunology found that women’s optimism increases their age for up to eight years for others less optimistic.

The study, led by Professor Eric Kane, professor of social psychology at Harvard University, included 70,000 American women who were subjected to psychological tests in 2004 to indicate their optimism and pessimism about the living conditions surrounding them. The study continued until 2012, The United States and the cause of death of women enrolled in the study; resulting in a surprising result, found that among the five most serious diseases that caused death, women were most optimistic about these diseases by 30% less than the less optimistic women.
“In other words, optimism in life may directly affect the vital processes within our bodies.”

The study also found that the most optimistic women were less likely to be infected than others by up to 52%. This is the first study of its kind linking the human behavior in life of optimism and pessimism and human health and the possibility of exposure to diseases leading to death.

2 – Science does .. very soon your face will become your passport
In a unique move, the authorities of the Aruba airport in the Caribbean islands began using the Happy Flow technology, which makes the passengers’ faces a travel visa without the need for a paper passport or a thorough inspection and inspection procedure that makes passengers have to wait long hours In the lines of inspection and personal verification.

The new smart technology relies on special cameras that can recognize the human face through the infrared technology. Once a passenger arrives at the airport carrying his personal data, the camera recognizes the features of his face and records all the data by communicating with his smartphone without the need for a passport Travel.

The current error rate for cameras is 1 per 100,000 people and can save $ 2 billion each year; the IATA seeks to expand the use of this technology across all airports in the world to reach more than 80% of airports by 2020.

Apple officially joins the auto-racing race
Apple announced this week that it intends to enter the entire auto-control industry, which is a vehicle that does not need to be driven by anyone, but is integrated with internal sensors to help it walk the road alone without a driver. This is the first time that Apple has entered the auto market as a manufacturer, but has already created auto-related sites on the Internet.

The electronics giant Google has entered the market early, along with Ford Motor Company, and Tesla Motors announced that all cars produced by the internal control devices, and were tested in Britain this summer and the experts found the need for further testing Before starting to be widely used across the world, which means – if it is – a major leap in the technology of the automotive industry.

4. For the first time in history, giraffes are threatened with extinction
Unfortunately, this week’s science news was not all that pleasant and promising; IUCN included the first giraffes for the first time in the list of endangered animals. The International Federation, which works with a large number of governments and human rights organizations, has noted that the number of giraffes has declined by 40 percent since the 1980s, with the number of giraffes dropping between 152-163 thousand in 1985 to 98,000 this year.

The reason is the illegal hunting of giraffes to obtain meat in conflict and poverty areas like southern Sudan, as well as the massive human expansion of agriculture to get more people to eat, which means the destruction of grazing areas.

5. Hearing high volume may cause long-term hearing problems
In a new study led by Brazilian ENT Tannet Jeans, a professor at the University of Sao Paulo’s School of Medicine, she found that hearing loud concerts leads to tinnitus and hearing problems that a person may not be able to get rid of.

The study included 170 students in a boarding school in Brazil where students were asked about the tinnitus associated with high voices and found that one-third of them had had this tinnitus, and some continued hearing problems for a long time.

The biggest problem in high sounds is that it may send a destructive acoustic wave to the block and then to the inner ear cells responsible for connecting the electrical impulses to the brain for hearing.

More strikingly, some of the students who suffered from high voices showed a weak response to the weak sounds that were exposed to them, which meant that the sensitivity of their ears to sound was impaired.

6- 100 million trees killed by drought in California!
The US Environmental Service Center (usfs) reported that nearly 62 million trees died this year alone in California as a result of the city’s droughts. Adding to the number of trees that died in the last six years, 102 million trees died in six aA rate that is much faster than all experts expect.

The greatest threat to human death is the increase in forest fires at an enormous rate, which hampers the authorities’ efforts to fight these fires in the future. The Center also predicted an increase in the number of trees that will die in 2017; drought has affected more than 7 million trees.

7 – Indian surgery is dangerous to Egypt is the heaviest woman in the world
Next week, Egyptian Iman Ahmad Abd Al-Ati will travel to Mumbai, India, for weight loss surgery. Iman s weight is about 500 kg, making it the heaviest woman in the world. The Indian doctor preferred Landward had agreed to carry out the operation after he continued with the people of Iman, who has become bedridden weight and has been unable to walk and movement since the age of 11 years.

Due to difficult financial conditions, Eman’s family could not complete their travel abroad. After the help of the doctor, the Indian authorities agreed to grant her a visa and travel next week for the operation.

Iman was born weighing five kilograms and her parents were said to have an elephant disease; a disease that greatly inflates the size of the body, but the Indian doctor ruled out that and predicted that obesity is the main reason for increasing the weight of faith; he said in an interview with the British Broadcasting Corporation « The BBC said the operation was a big challenge but was very optimistic about its success.
