Most powerful microscope in the world

British scientists have presented the most powerful optical microscope in the world, that can display detail of 50-billionth of a meter, and experts believe it will have greatest application in biology and medicine, especially the use of observation cells and study of viruses and bacteria.
The new technology uses short waves that are emitted close to the observed object, they break through the glass lenses and provide a view of the traditional microscope.
In this way, scientists will be able to see details with their own eyes that have so far been possible only through atomic force microscopy, and scanning electron microscopy.

People used fire more than 300,000 years

People began to regularly lodge fire about 300,000 to 400,000 years ago, the survey found that results today in Washington.

Summary of findings from 141 archaeological sites in Europe shows that the regular maintenance of fire began at this time, write the scientists from the Netherlands and the United States in the academic journal of the Academy of Sciences.

As noted agency Associated Press, says that people are mastered fire much earlier than indicated by this research.

Most archaeologists agree that fire is associated with the spread of the human species out of Africa, especially in Europe, where temperatures drop below zero.

But, although there is evidence that the ancestors of modern humans lived in Europe before about a million years, the oldest traces of regular use of fire are about 400,000 years ago, they said.

Neanderthals and modern humans who inhabited Europe have since regularly used fire for heating, cooking and lighting. Taking into account the harsh climate, there are scientists considered "clear but surprising.

These findings raise the question of how people manage to survive the cold without the fire, said agency Associated Press.

Scientists believe that the intense physical activity and foods rich in protein, enabled people to adapt to extreme climate. Added to the well-documented that the hunter-gatherers ate raw meat and fish.

Evidence of regular use of fire more than 400,000 years were found at one site in Israel, while in some localities in Africa revealed occasional fires.

Harvard archaeologist Richard W. Vrang, however, claims that mastering the art of preparing food, and about two million years, improve nutrition and contribute to the development of the brain, enabling the emergence of modern humans.

Vrang believes that the lack of so many old evidence means that the burnt bones and ashes have been destroyed or developed, the authors of the research challenge, since, according to them, in a cave in South Africa found burnt bones.

Discovered tyrannosaurus relative

Chinese scientists are in Mongolia have discovered a single dinosaur. This is the first dinosaur that belongs to the group with pelvic girdle as in today's reptiles (Saurischia), which has only one claw on the front paw.

Others tend to have three "fingers", the scientists explain in the journal Proceedings the American Academy of Sciences (PNAS).

From this group teropod, which are mainly carnivorous, and they are better known dinosaurs such as Tyrannosaurus and Veloceraptor. later evolved birds.

Chinese team gathered around the famous scientist Sing Sua from the Institute of Vertebrate Paleontology and Paleoanthropology at the Chinese Academy of Sciences in Beijing have discovered a relatively small dinosaurs in the rock between the ages of 84 and 75 million years ago (Cretaceous period). The formation Vulansuhaj, near the town of Linhe, on the border of China and Mongolia, but has found a large number of fossil remains.

In addition to the spine, the researchers found, and the front paws, part of the pelvis and hind legs that are almost completely preserved. One finger dinosaur was supposed to be about two meters high, and scientists named it Linhenykus monodactylus.

Supersonic car that reaches speeds of 1,600 miles per hour

Cars "bladhaund", on which construction is in Britain for three years, aims to be the fastest car in the world and to reach a record speed of 1,000 mph - or more than 1,600 kilometers per hour. This record speed "bladhaund" should be placed in the ride on a disused lake bottom in South Africa's Northern Cape province, end of 2012.

This car will run faster than the sound a jet engine mounted above the hybrid rocket motor, which is a combination that would provide 135,000 horsepower - exactly 180 formula1 force.

Engineers and experts in aeronautics company "Hempson indastriz" currently working on the construction of the last frame, where the jet and rocket engines placed, while making the front of the car are working engineers gathered in Advenst Komopozits Group.
Development "bladhaunda" simultaneously monitors and educational program in 4000 schools, which aims to inspire students to deal with the natural sciences, engineering, technology and mathematics.

The previous record for driving fast keeps Andy Green, who in 1997. in the vehicle "Trust SSC" achieved a speed of 760km / h, and it will be driver "bladhaunda" in South Africa during the test rides, which begin in January next year.

We'll need a new planet

During the last half century has increased dramatically, primarily energy consumption. If the trend continues until 2030. year will need another planet.

INVESTIGATION World Fund for Nature shows that humanity has for years not living in accordance with the possibilities. During the last half century has increased dramatically, primarily energy consumption. If the trend continues until 2030. year will need another planet!

Negative trends exist in multiple "fronts": on average, each resident spends one planet and a half times more than what nature can provide him. In industrialized countries the consumption is several times higher.

Then, one billion people lack drinking water. Since the seventies, then, in the world, a third, reduced the strength of the 2500 observed species in the tropics reduction is as high as two thirds! Seventy percent of all fish species endangered due to over-catch.

If the area of ​​the country was divided fairly and according to what nature can provide, each person would have a useful area of ​​1.8 global hectares. Since the seventies, however, consumption of humanity greatly exceeds the annual biocapacity countries to use 2.7 global hectares per capita. It is one and a half times more than what nature can provide.

In the last half century has drastically increased primarily energy consumption. It is growing rapidly and continues in countries such as China, India, Brazil and Russia.

- To meet the demand for food, energy and other natural resources is already practically need a different planet - said Eberhard Brandes from the German branch of the World Fund for Nature. - The prosperity in the developed world has paid the biological richness of other parts of the world, among others, tropical regions.

This is reflected in the human environment - in tropical areas the numbers of species, which are monitored, reduced by 60 percent in the moderate climate of 29 percent. Branders also showed a photograph - of the tropical forest in Sumatra, was set up camera-trap, which was supposed to save the tiger. The photograph shows bulldozer which clears a forest ...


How much who have

Especially luxurious living in the United Arab Emirates, where everyone has ten acres, and "belongs to him," and on the planet every 1.8 acres. Followed by Denmark, Belgium and the United States. Germany has five global hectares somewhere in the middle. On the back of East Timor, Bangladesh and Afghanistan with 0.5 global hectares. So a man already consumed by half biocapacity more than what is available. In addition, most developed countries live at the expense of underdeveloped countries and rapid development.

New Galaxy’s

The space agency NASA said on its website photos unprecedented galaxies, asteroids and stars, recently recorded by telescopes WISE (Wide-field-Infrared Survey Explorer).

Thus, the infrared telescope, worth $ 350 million, managed to record 2.7 million pictures of the universe. Among them was found 33,000 never seen asteroids located between Mars and Jupiter. New footage found another twenty comets. NASA began the project by 14 December 2009 and now is unique in that it can scan the cosmos.

In response to the heat of heavenly bodies, the device can collect pictures and data about distant comets and asteroids that current telescopes were inattentive. Among the most famous discoveries is the giant Andromeda galaxy. This bluish oval is located two and a half million light years from us.

Approximately 57 percent of records, NASA has announced on the Internet, and finally research should be completed next spring.

But the advantages of this telescope were completed six months ago. For heat-sensitive devices in the function held a special liquid, which was missing last October, and since February this year the telescope is into "hibernation".

Swearing relieve pain

Scientists found that swearing when you are in pain, may have the same effect as any painkiller.

Shouting curses when we are in pain is an old reflex that should not be ashamed of, because it allows us to really relieve the pain, according to a recent survey.

A group of scientists from the University of Kiel found that swearing can have the same effect as any painkiller that is especially effective in people who seldom utter simplicity.
To verify this theory, the researchers asked the volunteers to keep their hands in ice water and pushing all the time swearing.

Then they repeated the task, but this time with the pronunciation of the word innocuous.
It turns out that the volunteers with the swearing to much longer to hold his hand in ice water. The effect of swearing was four times higher in people who have the habit of the so expressed.

"People curse for centuries, it is practically a universal linguistic phenomenon", said Dr. Richard Stevens, who participated in this study, adding that the researchers tried to explain the reason of curses and their persistence.
