Nine rescued the 58 stranded whales in northern New Zealand

Nine pilot whales have been rescued from a group of 58 who were stranded on Friday on a beach in northern New Zealand, official sources said today.

Authorities found only 15 of the whales alive and managed to return 13 to sea for the weekend, but four stranding again and died, said Sioux Campbell, spokesman for the Department of Conservation.

"Fortunately, we have not seen the whales today, which is good news. We are very happy to have saved the whales with the help of the community," said Campbell.

About 70 volunteers worked tirelessly to keep afloat and breathing mammals despite weighing a ton and a half.

Two years ago, more than one hundred pilot whales were caught on the beach in New Zealand, Australia and the neighboring sees each year hundreds are killed marine mammals in their costs.

Scientists do not know the reason why some species of whales end their days on the beaches, and shuffled the possibility that sonar attracted by large ships or to follow a group leader disoriented by illness.

Scottish scientists create biofuel Whisky

Scottish scientists created biofuel from waste in the manufacturing process of the whiskey, same as common car may be used without additional mechanisms.

According to British newspaper reported Thelegraph, Professor Martin Tangney, who heads the research group, this invention fulfills the environmental policy of the European Union announced its intention to achieve that 10 percent of the cars using clean fuels for 2020.

Today scientists, who took two years to the development of this biofuel, think about how to make the product available to as many consumers as possible.

"More probable is that biofuel is not used pure: safely be mixed with gasoline or diesel," he explained.

Scientists Spot column of 35 km. spill residue BP

The oil spill from the well damaged in BP in the Gulf of Mexico released a hydrocarbon column of over 35 kilometers long and 200 meters high, situated at 1,100 meters deep, according to a study published today in Science.

The study, conducted by the Woods Hole Oceanographic Institution (WHOI), said that the explosion and sinking of the rig Deepwater Horizon in April created a column of waste as natural degradation is very slow.

The WHOI team calculated the size of the column from 57,000 chemical analysis, made in June during an expedition aboard a submarine capable of exploring the ocean up to 4,500 meters deep.

"Not only have we demonstrated conclusively that there is a column, but we have defined its origin and approximate structure," said Richard Camilli Science, one of the scientists from WHOI, which indicated that the columns of waste were far , mere theories in the literature "scientific.

Camilli, who is also the lead author of the study, added that the levels of hydrocarbons detected in the column are "significant."

The team traveled in a zigzag column 19 times to determine its size, shape and composition, the study said.

During the tour, sampled through a tool that measures ocean conductivity, temperature and water depth.

Once in the laboratory, they found that the samples, but colorless and odorless, contained concentrations of hydrocarbons, including benzene, toluene, and xylene-etibenzeno more than 50 micrograms per liter.

This conclusion contrasts with that obtained by the U.S. government, which last August 4 presented a scientific report according to which 74 percent of the 4.9 million barrels of oil that spilled into the ocean has been collected since April , burned, vaporized or decomposed by natural processes.

"It has spread a rumor that the particles were being degraded oil naturally and easily. We have not seen that. We have seen that are still there," Camilli said.

However, scientists found "dead zones", ie areas of the spine devoid of oxygen which could not survive fish or other marine animals.

However, for the WHOI geochemist Benjamin Van Mooy, the study gives cause for alarm.

"If oxygen samples tell us that microbes are not close to degrading the oil well, oil could persist for a while. So it is possible that oil is transported considerable distances before being dissolved," he said.

Ecology up in the air conditioning

Large amounts of energy is for the use of air conditioners, especially in Verena. In the case of United States 5% of the total energy is used in refrigeration systems.
Well, now we have developed an air conditioning system that could increase energy efficiency succeeding in reducing emissions of greenhouse gases, this research was conducted by a group of scientists at the National Renewable Energy Laboratory U.S..

Eric Kozubal together with a group of engineers have created an air conditioning system that consumes up to 90% less energy than other systems.

The DEVap is based on the classic combination of evaporative cooling with a material that absorbs water, getting cold, dry air.

The interesting thing about this innovative new system is the combination of evaporative cooling technology, says Eric Kozubal.

If the whole project ends in positive results, it should be commercialized within five years, supporting the care of the environment and reducing CO2.

Warn of damage pathological Internet use

Teenagers who use the Internet in pathological form are more likely to develop depression than those who do not, according to a report published online today by the Journal of the American Medical Association (JAMA).

According to the article, since the mid-1990s, pathological Internet use, that is uncontrolled and unreasonable, has been identified as a problem behavior with signs and symptoms similar to other addictions.

Such use has been associated with health problems, aggressive behavior and other psychiatric symptoms.

Medical experts from Australia and China studied the pathological use and later mental health problems among nearly 50 thousand teenagers from 15 years in average age in China.

Participants were evaluated for depression and anxiety using previously validated scales.

Moreover, young people completed a questionnaire to identify pathological Internet use, including questions that reflect a typical addictive behavior.

According to the authors of the study, "this result suggests that young people who initially did not have mental health problems may develop depression as a result of pathological Internet use."

The study's analysis indicated that the identification of individuals at risk in the school environment could be considered an effective strategy for early prevention.

The report suggests that early intervention could reduce the burden of depression and subsequent mental health problems among young people.

Therefore, a program for the detection of pathological Internet use could be considered in secondary schools to identify individuals at risk for further advice and treatment early.

Japan and Australia hosting 500,000 species unidentified marine

Australia and Japan host more than half a million marine species not yet identified by scientists, who work piece before they disappear because of global warming.

"Australia has a tremendous ecological interest, from coral reefs to the ocean floor," said Jesse Ausubel, a researcher at the Australian study, titled "What lives in the sea."

The rich ecosystem Australian bathed by three oceans and four seas, which extends from the Tropic of coral to the South Pole ice, hosts some 250,000 unidentified species.

"This is a great diversity of habitat and oceans that have only been partially investigated," said Alan Butler, of the Organization for Scientific and Industrial Research of Australia.

Most of the 33,000 species listed by scientists in Australia were birds, seabirds and marine mammals, and new fish and sharks, which represent 20 percent of marine life to discover.

In the Great Barrier Reef in northeastern Australia, live in the greatest number of species such as corals, dolphins, sea turtles and pigs.

For its part, Katsunori Fujikura, the Agency for Technology and Earth Sciences and Sea of Japan, said oteadas 155 000 species have been in the waters of his country, a mere 30 percent of the total, only 33,000 have been officially registered .

"The cause of such diversity is undoubtedly due to the variety of natural environments found in Japanese waters," said Fujikura.

The Japanese marine environment, covering an area 11 times larger than its land mass, home to coral and marine ecosystems to 10 kilometers deep.

Due to the strong currents, only 5.6 percent of the species in Japan are unique on the island, while 19 percent of the 17,000 New Zealand marine species limit their habitat around the islands.

90 percent of marine life in Antarctica is more than a mile beneath the surface of the ocean and only 11 percent 9000, has been studied species.

"Most of the species in the Antarctic Ocean are rare. Half of the species on the seabed have been spotted only once or twice," said Huw Griffiths, a researcher at the British Antarctic Survey.

The research at the South Pole is essential to understand the process of climate change, as it is the regions most affected by global warming.
