Brain Scans Could Predict Suicide Thoughts

A new study shows that brain scans might be able to find out if people are thinking about killing themselves. Scientists have trained a computer program to examine the thoughts of people based on brain scans.

The study examined two groups of people – one group were known to have suicidal thoughts and the other group were without such thoughts.  During a brain scan doctors gave them words related to certain topics. Ten words were related to positive things, like “carefree” and “praise“, the other ten were connected to negative things like “desperate” and “death”.   The computer program then recorded the emotions they were feeling.

Researchers said that in 94 % of all cases they could identify people who had suicidal thoughts.They were also able to find out who had attempted suicide before.

This new experiment gives scientists a method of looking at what goes on in your brain and what you think about topics related to death.

According to the World Health Organisation, about 800,000 people die from suicide every year. In the United States, it is the second largest cause of death in the age group between 15 and 24. Although the findings are not 100% accurate,  we may be able to assess a person’s mental health by looking at brain scans in the near future.

Mysterious Chamber Discovered in Egyptian Pyramid

A mysterious chamber in an  Egyptian pyramid has been recently discovered by scientists. A special technique shows a  large void hidden in the Great Pyramid of Giza  near Cairo

The ScansPyramid project, led by the University of Cairo and the Egyptian government,  uses advanced technology to find out more about ancient structures. Scientists from Egypt, France and Japan installed special detectors which could detect small particles called muons. These are a type of cosmic rain which constantly falls down on the earth. Three separate teams have conducted the research and have found the same cavity in the pyramid.

The newly found chamber in the Egyptian pyramid is 30 metres long and about the size of the Grand Gallery which is a known passageway that leads to the King’s Chamber. However, nothing else is known about the new room. It is also impossible to reach the space as there is no passage that leads to it. Experts also warn against having great expectations about new discovery inside the cavity.  It is possible that the void does not have any meaning at all and was just left there for construction reasons.

The Great Pyramid, also known as the Pyramid of Khufu, was built at around 2650 BC. after the death of the pharaoh. It is the largest of the three remaining pyramids at Giza, which belong to the wonders of the ancient world.

Asteroid That Wiped Out Dinosaurs Led to Severe Winter

Scientists have now found out that the asteroid that hit the earth and led to the extinction of the dinosaurs 65 million years ago also caused a long period of winter and extremely cold temperatures.

The asteroid hit the Yucatan peninsula in Mexico and created a crater with a diameter of 15 km. As a result about three-quarters of all plant and animal species died, including the dinosaurs. The impact sent tons of dust and sulphur gas into the atmosphere.

Now we know that three times more sulphur gas was catapulted into the atmosphere than previously thought. Sunlight was blocked from getting in, which resulted in much lower temperatures. A new study shows that temperatures worldwide dropped to about -10° Celsius for at least three years after the impact. Thus, the earth was plunged into a deadly winter, which many plants and animals could not survive.

While air temperatures probably rose shortly after impact, ocean temperatures may have been affected for centuries. Scientists also found out that the amount of carbon-dioxide that was released into the atmosphere was probably over-estimated.

In new research on the Yucatan peninsula, scientists drilled into the surface of what’s left of the crater and collected rock samples. This allowed them to examine and reconstruct what happened.

Protestantism Celebrates 500th Anniversary

This year marks the 500th anniversary of the Protestant religion. On October 31, 1517, Martin Luther published his 95 theses, which criticized the Roman Catholic Church. As a result, the new religion broke away from the high church in Rome.

Luther nailed his list of criticism on the door of a church in Wittenberg, where he taught theology. He attacked the Church because it claimed that a sinner could reduce God’s punishment by giving money to the church. He also claimed that popes were too powerful and abused their power.

A few years later Martin Luther was excommunicated from the Roman Catholic Church. However,  because of the printing press, which was invented at that time, his message spread across most of Europe. The Reformation caused widespread change in Europe. It led to wars and people leaving their home country in pursuit of religious freedom.

In England, Henry VIII broke his ties with the Roman Catholic Church and, based on Luther’s theses, founded the Anglican Church.  Over the centuries Protestants have created many different branches of their religion.  Many Protestants are found in Scandinavia, Germany and the United States.

About 800 million Protestants live in the world today. Even though there are still many disagreements between Protestantism and Catholicism, both churches have overcome their differences. Their relationship has improved since the 16th century.

The anniversary was celebrated throughout the Protestant world. Most ceremonies took place in Germany, the cradle of Protestantism.

Environmental Pollution Kills More People Than Smoking and Wars

A new report concludes that environmental pollution is world’s number one killer. Every year it kills more people than global wars , natural catastrophes,  or hunger. About 9 million people die prematurely every year because of our polluted environment.  Experts state that this costs  about $4.5 trillion  a year, 6% of the world economy.

Researchers say that pollution has never reached such a dangerous level before. Pollution-related deaths are one and a half times higher than the number of people killed through smoking and six times higher than people who die in road accidents. The real figures are thought to be even higher because pollution isn’t monitored in some remote place in Africa , South America or Asia.

Two thirds of the deaths are caused by air pollution. Burning wood and coal, as well as fumes of cars and other vehicles cause 6.5 million deaths every year.

The authors of the new report examined not only air quality , but took soil and water probes as well. They received additional data from the World Health Organisation.

Most of the deaths  occur in poor developing countries  , where governments care less about the environment and do not have strict laws in effect. Bangladesh and Somalia are among the most polluted countries.  In India, the second most populous country in the world,  one out of four deaths is caused by some form of pollution. China’s environment is also considered to be one of the deadliest  in the world. 

On the other side Sweden and Brunei have the lowest pollution levels. Pollution in developed countries is especially high in low-income areas of large cities, whereas  the rural countryside shows very low pollution levels.

The report makes a few recommendations . Fighting pollution should become a priority everywhere and more funds should be made available to combat pollution.

More Amazon Rain Forest Destroyed By Mining

A recent survey , examining the years between 2005 and 2015, has come to the conclusion that more and more of the Amazon rain forest is lost due to mining operations. According to the government, most of these mining activities  are illegal and unregulated.

Brazilian environmental organisations  now say that mining is one of the major problems of the Amazon rain forest. Whereas earlier estimates put the destruction through mining at about 2% of the total area, experts now say that over 10% of rain forest loss is caused by mining. Most of the rain forest is cleared to create settlements for mine workers , as well as new transportation routes  and airports. Minerals mined in the Amazon region include iron ore, bauxite and copper.

The destruction of the rain forest through  mining is 12 times greater outside official and regulated  areas than within. In some cases  observers saw mining activity up to 70 km from a mine’s border.

Rain forests are essential to the planet’s climate. They bind carbon dioxide and provide a living space for many plants and animals . Since 2000 more than 190 000 square kilometres of the Amazon rain forest have been cleared.  The leading cause of deforestation is still farming.

Officials  also report that, for the first time in years, deforestation throughout the year has  actually decreased – by 16 % between  August 2016 and July 2017.  This is a result of more surveillance and stricter controls, but it is also caused by lower livestock prices on world markets.

Australia Bans Climbing Uluru

Authorities at Uluru National Park have announced that tourists will no longer be allowed to climb up to the top of Australia’s most famous landmark. The ban will take effect at the beginning of 2019.  Officials say that  Uluru, also known as Ayers Rock,  is not an entertainment park, like Disneyland.

About 250 000 people visit the large red monolith in central Australia every year. However, only about  16% want to climb the rock.

Although Australia’s government  wants to keep the site open for hikers to climb, the decision was made out of respect to the native Australians who consider Uluru as a sacred place. In 1985 the government returned it back to the aboriginal people of the region. For a long time , local residents have asked visitors not to climb the rock out of respect.

National park authorities are worried that hiking to the top of 1,100 ft high rock will damage the UNESCO World Heritage SiteTour operators are now in search of other ways to show the monolith to its visitors, including camel rides around it.

Uluru National Park  is open all year round, but climbing is only allowed on certain days because of strong winds and other weather conditions. Climbing the rock is not always safe. In the last 70 years , 35 people have died in climbing accidents.

Not all locals, however, are in favour of the ban. Some say that hiking should only be allowed  with  a guide  and on special pathways.

More Billionaires in Asia Than in US

For the first time in history there are more billionaires in Asia than in the United States. But, the amount of wealth among American billionaires is still higher than in Asia. There are a total of over 1500 billionaires in the world today , 10 % more than last year.  According to a new business report, one new billionaire pops up every second day.

The overall wealth of American billionaires reached $2.8 trillion last year, while Asian billionaires accumulated a total of $2 trillion.  If the trend continues,   within four years , Asian billionaires will have overtaken America . The combined wealth of the world’s billionaires has  increased to over $6 trillion.

The new Asian billionaires come mostly from India and China. Most of them make their money in consumer industries and technology. Especially in China,  billionaires are younger than elsewhere. Some haven’t even reached the age of 30 yet.

The new billionaires in Asia are investing large sums of their money in sports. They are buying whole sports teams in their home country as well as in Europe. Art and museums are other areas of interest for the new billionaires.

Scientists Find Connection Between Sugar and Cancer Growth

A Belgian research team has found out that there is a connection between sugar consumption and the growth of cancer in a person’s body.

Scientists have found out that sugar not only gives us energy but may also be responsible for faster-growing tumour cells of cancer patients. Although  there is no proof that eating less sugar is good for cancer growth there are indications that if there are already cancer cells in your body sugar can make them grow faster. Low sugar diets, therefore,  could be beneficial for people who already have cancer.

The study shows that cancer cells process food differently than healthy cells in the body.  They also break down glucose, a form of sugar, more rapidly.

The research has been carried out for 9 years and now gives doctors new insights in the connection between sugar and cancer.

US Government Releases Most JFK Files

The American government has released over 3000 documents relating to the assassination of John F. Kennedy in Dallas in 1963.  President Trump, however, has ordered some of the documents with sensitive information to be held back for 6 months after a request from the CIA and FBI. In 1992 President George Bush signed a law that required all documents about the JFK murder to be released within 25 years.

The published documents have not provided any sensational new information on the JFK assassination. The public had  hoped that the released documents would bring more light into the former president’s murder. Experts say that the decision to withhold some of the documents suggests that the government wants to keep some things secret .

Many of the documents are incomplete and some are only memos. The files show how disorganised government agencies were during the 1960s and how they dealt with the assassination.

In a series of memos, the FBI reports on Lee Harvey Oswald’s visit to Mexico City, where he met with a Soviet agent shortly before the Kennedy was killed. The material shows that authorities were trying to find out if a foreign government – Cuba or possibly the Soviet Union – was behind Kennedy’s death.

There is still no evidence that there was a conspiracy to kill the president. Nothing suggests that Lee Harvey Oswald worked with a partner.  There are, however, FBI documents that warned the Dallas police about a threat against Oswald. Kennedy’s killer was shot dead at the Dallas Police Department two days after the Kennedy assassination.

Among the documents are reports that are only indirectly related to the Kennedy killing, for example CIA plans to murder Cuba’s Fidel Castro .
