Astronomers say new planets continue to be discovered as scientists measure the slight vibration of the distant star the planets orbit - caused by the planet's gravitational pull. In 1999 there would be 28 of these planets outside of our solar system. The new ones that would have been discovered are about the size of Jupiter or more. Jupiter's mass is approximately 318 times that of Earth. Like Jupiter, planets are believed to be made up of helium and hydrogen. Because of the orbits of these planets, it is said that planets the size of Earth are very unlikely to coexist with them. In contrast to the 150 million kilometer long earth orbit, they orbit their stars in oval orbits. An orbit ranges from 58 million km to 344 million km of its star. "It looks like perfectly stacked orbits like the one we see in our own solar system are relatively rare," said one astronomer.

Whistle communication

Spanish students on the island of Gomera, one of the Canary Islands, must learn the sizzling language that has been used by local pastors for centuries, reports The Times of London. Originally developed as a means of communication through the valleys of mountainous terrain, the Gomera Silbo (whistle) uses sounds to imitate spoken syllables. Pipers put their fingers in their mouths to vary the tones and raise their hands to spread the sound - up to two miles. Almost lost in the 1960s, the whistle regained popularity and the island began an annual Whistling Day. There are limits, however. "You can talk, but there isn't much to talk about," says Juan Evaristo, director of local education.

Children and sleep

"Parents have to set limits, not only how many schoolchildren can stay up late, but also what they can do before bed," explains the parenting magazine. “Watching TV, playing computer and video games, and surfing the Internet are stimulating activities that kids do overtime. And a plate full of after-school obligations prevents them from completing their homework in a timely manner. Research shows that sleep deprivation tends to have different effects on children - they become hyperactive and uncontrollable, while adults are sleepy and calm. As a result, sleep deprived children cannot focus, pay attention, retain what they are learning, and solve problems in school. Experts say parents need to set a time when their children can fall asleep and have priority - not a last resort after strenuous activity or energies.

AIDS in the world

According to a new United Nations report, "more than 50 million people around the world are infected with HIV-AIDS - the equivalent of the UK population - and 16 million have died," says The Globe and Mail of Canada. "Research in nine African countries found that 20% more women than men are infected with the disease" and that "teenage girls are about five times more likely to be infected with HIV / AIDS than teenagers". Peter Piot, Executive Director of the United Nations Joint Program on HIV / AIDS, describes the situation in Eastern Europe as "explosive". The report finds that "the rate of HIV infection in the former Soviet Union has more than doubled in the past two years," largest increase in the world. "Experts say this reflects increased use of intravenous drugs in the region. Diseased worldwide more than half of people infected with HIV / AIDS "by the age of 25 from the disease and generally die before the age of 35".

Sunscreens and cancer

"Using high factor sunscreens may make people feel less safe and may increase their risk of skin cancer," reports The Times of London. "That's because they spend more time in the sun and absorb more radiation." Researchers at the European Institute of Oncology in Milan, Italy found that those who used sunscreens by factor 30 spent 25% more time in the sun than those who used factor 10. According to Phillipe Autier, l 'study author:' The effect A protection for the use of sunscreens against skin cancer, especially melanoma, has not been demonstrated in the general population, but there are convincing data that show a strong association between the duration of recreational and sun exposure Show skin cancer. “Health professionals now warn against prolonged exposure to the sun, regardless of the level of protection against sunscreen. Christopher New, cancer health campaign manager for the UK Health Education Authority, advises, "Don't stop using sunscreens, but remember that if you want to keep your tan longer."

The ideal transport?

Pedicabs, also called trishaws or cycle rickshaws, have been used in India for decades. However, Outlook magazine notes that they have remained unchanged and have "a heavy wooden structure, a large cast-iron structure, poorly lying benches and no equipment". In recent years, there has been strong opposition to its use due to pressure on drivers, who are generally older and malnourished men. Now that air pollution in India is reaching dangerous levels, the rickshaw cycle has come to life. A Delhi-based company presented a design with a much lighter and more elegant structure that reduces wind resistance, a gear system that dramatically reduces pedaling effort, ergonomically correct saddles, handlebars that reduce wrist fatigue, and a more spacious and comfortable passenger. Seats. According to T. Vineet, the project manager, "This fits into today's politically correct scenario where human rights and an environmentally friendly environment are the buzzwords." According to Outlook: "The humble rickshaw could become the ideal means of transport in the 21st century".

Irreplaceable mail

To date, "technology could not replace the effect of a letter," according to the Le Figaro newspaper. In 1999 the French Post delivered a record of 25 billion letters. Of this, 90% was business correspondence and only 10% personal correspondence. Almost half of all emails sent contained some form of advertising, which 98% of respondents read carefully. Every day, the 90,000 French postmen, 40% of whom are women, make more than 72,000 rounds to deliver the 60 million letters sent every day.

Affected Subscribers

The French newspaper Le Monde reported that 1999 was "a cursed year for reinsurance". The 1998 natural disasters caused $ 90 billion in damage, of which insurers reimbursed $ 15 billion. However, 1999 - marked by earthquakes in Turkey and Taiwan, typhoons in Japan, floods in India and Vietnam, and other disasters - could cost insurers even more. Insurers are concerned about the increased likelihood of major disasters in densely populated areas. The world's leading insurer warns of "the devastating effects" of global warming and "the consequences of human activities under climatic conditions".

Mount Everest now a single studio

"Mount Everest, the highest mountain in the world, is even a workshop of what scientists thought and continues to grow," said a recently published Reuters report. “With sophisticated satellite systems, climbers have measured Everest at 8,850 m - about 8.9 km high. . . This is seven feet above the previous official 1954 measurement of 29,028 feet. "The new measurement is the height of the snow-capped peak. The height of the actual rocky peak below it is still unknown. National Geographic Society adopts the new cipher for their cards.In addition to climbing, the mountain - the entire Himalayan Mountains in fact - moves from 1.5mm to 1/16 of an inch northeast towards China 6mm per year.
