A new study published in the British newspaper "The Guardian" revealed that a large proportion of salt water in many countries of the world are contaminated with plastic.
This study renews the experts' fears that plastic particles will become widespread "in all the seas of the world", which may pollute the environment and contaminate our meals.
The study showed that small particles of plastic were found in tap water in the United Kingdom, France, Spain, as well as China and the United States.
Researchers believe that this water pollution is caused by plastic "used once", such as water bottles, soft drinks and products that make up the majority of plastic waste.
According to the United Nations, up to 12.7 million tons of plastic enter the world's oceans each year, which is equivalent to dumping a plastic garbage truck in all the oceans of the world within a minute of time.
Experts say the very small plastic particles are less than 5 millimeters in diameter, warning of their danger to human organs, especially the intestines.
Scientists at Texas University, revealed a pen-shaped tool that can identify cancer tissue in 10 seconds.
The pen, called "MasSpec Pen" works to accelerate the testing process up to 150 times faster.
According to the media reports, that the tests carried out on 253 cancer patients took about 10 seconds and were found that it 96 percent accurate during that time period.
Tests included tissue related to breast, lung, thyroid and ovarian cancer, and scientists explained that each type of cancer had its own molecular structure.
The pen shows the word "natural" or "cancer" automatically on the computer screen, and may show the name of the subtype for some cancers.
"All the hurricanes that hit America come from one place," said a video posted on "Tech Insider" channel on YouTube.
The source said the hurricanes originated from a point in the West African coast near Cape Verde, where hot air from Central Africa meets with cold air from its north, causing winds that generate hurricanes moving to west across the Atlantic toward the United States.
Hurricane Harvey hit Texas in the United States a month ago, at a time when another hurricane named "Irma" heading Florida, which saw the largest evacuation in US history.
The US Hurricane Center announced that Hurricane Irma had intensified to the fifth maximum on Saturday night as the devastating hurricane began to invade the island of Cuba after causing heavy casualties in many Caribbean islands.
He said the hurricane was accompanied by strong winds of up to 260 km per hour and was heading west with 20 km / h, on a path that would increase dangers that it poses in Florida.
The hurricane is expected to hit Florida on Saturday, which has the largest evacuation in US history, including approximately one million people.
US meteorologists on Friday called on residents of the Florida Keys to evacuate their homes and leave the area before the hurricane come.
In a statement, US President Donald Trump said: "This storm definitely has historic destructive potential ... I ask everyone in the storm's course to exercise caution and take into account all the recommendations of government officials and law enforcement officials".
British scientists said that it is possible to treat depression by anti-inflammatory drugs, having concluded that it is an organic disease.
The scientists added that they reached this solution after the diagnosis of depression as an organic disease caused by a defect in the immune system, according to the newspaper "Telegraph" British Saturday.
This study is consistent with several previous studies that linked depression and the immune system, and noted that it is an organic disease and not a disease of pure mental origin.
One of 13 Britons suffers from depression or psychological distress, and health authorities issued 64 million prescription recipes for depression last year.
The current treatment focuses largely on mood-enhancing drugs, especially serotonin boosters in the brain, but scientists now believe that excessive activity of the immune system leads to inflammation throughout the body, causing feelings of despair and fatigue.
The new study showed that the treatment of infections in the immune system reflected positively in reducing the state of depression.
The head of the Department of Psychiatry at Cambridge University Ed Bolmore, said that a new treatment in immunology is on the horizon, he said "it is very clear that inflammation causes depression".
Scientists at Cambridge and others at the Wellcome Trust Fund for Medical Research hope to start treatment trials next year, to test the ability of anti-inflammatory drugs treatment of depression.
Bullmore added that there is evidence showing the ability of these antibiotics to treat depression.
Fourteen people have died in north-eastern Nigeria from cholera, where Nigerian authorities said the majority of the victims were staying in a camp for refugees who had fled their homes because of attacks by the extreme Boko Haram group.
The Health Ministry in Borno state said in a statement received by AFP: "On the first of September recorded 14 deaths," noting that "the number of suspected cases of cholera rose to 186."
The majority of the suspected cases (179 cases) and deaths (10) were recorded in the camp of Mona Karaj, Near Maiduguri, the capital of Borno State, while the remaining cases were recorded in Neighborhoods nearby.
The statement said that the health authorities, in cooperation with the humanitarian organizations in the region, have taken measures to combat the spread of the epidemic, such as water purification and the development of more latrines.
