Meteorological week analysis
Meteorological week analysis – After analyzing the meteorological data from the years 1991-2005,
the German researchers found that the hottest day of the week is Wednesday, and the driest – Monday.
However, in the weekend usually it rains. Within a week, smog obscures the sun and the exhaust gases
are involved in the formation of clouds. On Saturday, this phenomenon goes critical.
Antarctic temperature changes
Antarctic temperature changes – Researchers at the University of Washington in Seattle (USA),
after analyzing data from satellites observing Antarctica, came to the conclusion that Antarctica
warmed by 0.5 ° C between 1957 and 2006. Scientists noticed that the temperature
quickly rises to the west Antarctica. Heating the continent has an impact on rising sea levels.
Electronic nose – Detects and analyzes smells
Electronic nose – E-nose is a device that detects and analyzes smells. It successfully replaces the human organ of smell, eg. When assessing the quality of the product.
Snowman Yeti – DNA analysis of hair samples
Snowman Yeti – The legendary Yeti snow man certainly does not exist. At least, so they say scientists after DNA analysis of all available samples of hair that were alleged to come from the Himalayan creation. It turned out that they belonged to the bears and goats. They collected and analyzed a total of 30 samples.
Smoking threatens deafness
Smoking threatens deafness – British scientists from the University of Manchester conducted hearing tests on a group of 165 thousand. men and women aged 40 to 69 years. Which was a representative sample of the British population. The results largely confirm previous analysis and showed that suffers from hearing loss approx. 30% of smokers. It turned out that between the risk of hearing loss, and smoking, there is a direct relationship.
Primary Mental Abilities – Variety of independent skills
Primary Mental Abilities – Louis Thurstone (1887-1955) believed that using factor analysis can uncover a variety of independent skills. He called it the basic mental abilities (Primary Mental Abilities, PMA), and created a special test to measure them (PMA test). He appointed six basic mental abilities: understanding words, verbal fluency, the ability of numerical, reasoning ability, memory and perceptual speed.
Martian life – Theoretically it is possible
Martian life – Could exist only in the first 600 million years of its existence. At least, so say scientists from the University of Rhode Island. Climate that prevailed at the time on Mars was wet and warm, experts believe. Theoretically, it is therefore possible that life arose here. Unfortunately, over time the planet dry and reigned on the hostile conditions in which they could not survive even the simplest organisms. Team of researchers came to these conclusions based on the analysis of mineral samples from Mars. The change came about. 4 billion years ago and was most likely the result of volcanic eruptions. Since then, the minerals formed without the aid of water and are very rich in iron.
