A recent study conducted in India mentioned that electromagnetic waves from a transmitting tower and cell phone signals also can endanger the existence of mobile phones honeybees.

The experiment conducted in Kerala, India is finding a decrease in the number of honey bee populations drastically. After investigation, it seems this is caused by an increase in the number of towers built in the area.

Mobile phone operators say the reason they reproduce the signal relay towers course is to improve the quality of their networks. But they did not realize these actions threaten the community of living things around him, one of the bees.

"Electromagnetic waves emitted by these towers crippled navigation capabilities that worker bees collect nectar from the flowers to maintain the continuity of the bee colony," said research team leader, Dr. Sainuddin Pattazhy as quoted by the Times of India, Tuesday (1/9/2009).

Pattazhy and his team conducted a study to put the phone near a beehive. In fact, cell phone signal eliminates navigation capabilities and lead to worker bees they could not find a way back to the nest.

Because he could not return to the nest, the bees in the hive is the queen bee live together with the eggs. This then causes a decrease in the number of colonies of bees. In a study conducted Pattazhy, many bee colonies are reduced and finally collapsed only within 10 days.

"If the number of mobile phones and towers continues to increase, it is certain that in the next ten years we can no longer see the presence of honey bees," said Pattazhy.

Experimental procedures on monkey transplant DNA opens the way for a new method for human pregnancy. The success of the transplant experiments monkey DNA allows pregnant women to avoid a particular genetic disease to their fetuses.

The success of the team from Oregon Health and Science University in the birth to the birth of four monkeys cause the results of a DNA transplant new optimism in the world of science.

Although this technique is considered stepping over the ethical and safety is still questionable, but the observers praised the success of this science as a result of impressive research. This experiment involves the transfer of DNA between the egg cell of the blood group of Macaca monkeys.

"One day, this technique can be used to cure diseases caused by defects in the cells' power plants" called mitochondria, "said one researcher, Shoukhrat Mitalipov quoted from Yahoo News, Thursday (27/8/2009).

An egg contains most of the DNA in the nucleus, but mitochondria contain DNA that take place in the egg cell. Thus if a pregnant woman has a disease caused by mitochondrial DNA damage, this new technique could someday allow them to not pass it on to the fetus.

"There have been many experiments performed safely in monkeys. Undeniably, this technique will face many regulations in the study of humans, especially about ethics," said Mitalipov.

He mentioned this is very possible, because the experiments they are doing will change the DNA legacy for the next generation of the spotlight in terms of scientific ethics.

A recent study says, there is the possibility that the growth of algae contribute to the dinosaur extinction.
At approximately 540 million years ago, occurred the destruction of five types of organisms in large numbers. In this case, 50 to 90 percent of these extinct organisms are species of animals.
The results of studies conducted James Castle and John Rodgers of Clemson University says, toxic algae play an important role in the extinction of five organisms of Earth, including the best known species of loss of animal populations dinosaurs approximately 65 million years ago.
"We did not find any fossils gangang during extinction of the dinosaurs. But we suspect, other forms of algae have a role in the extinction process," Castle said as quoted by LiveScience, Tuesday (3/11/2009).
Algae are very simple organisms that obtain energy from sunlight. Some species of algae produce toxins that harm other aquatic organisms and humans.
For example, one group of algae called dinoflagellates can release neurotoxin or nerve poison that attacks the nerve cells.
Algae and other microorganisms can grow rapidly and can collect a dense population when he got an abundance of nutrients. This situation is usually called the 'algae blooms'.
At this time, toxic algae will spread and have effects that can destroy entire ecosystems, such as fish, marine mammals, birds and even humans.
But Castle and Rodgers mentioned, this hypothesis does not mention that the algae is the only factor of extinction of the dinosaurs and other prehistoric organisms.
Both are considered gangang as part of "kill mechanism" in the process of natural selection.

Internet experts for being confused with a town called Argleton in the Lancashire, England. Because the existence of these cities is detected in the Google Maps service and online directories. But in reality, the city was not really there.
In Google's services, Argleton located near the fast lane M58, named the area south of the city Ormskirk.Keberadaan indicates that the software and online systems to detect the presence of these areas and automatically think of it as a real city in the UK and included in the L39 postcode area.
Google and other companies that provide such data can not even explain the presence of 'ghost town' and until now still doing further investigation. Such information in the quotation from the Telegraph, Monday (2/10/2009).
Allegations as to explain the presence of Argleton on Google Maps is a theory which states that 'ghost town' may be deliberately added to the Google Maps as a trap to catch companies that violate copyright mapping system.
"Maybe this is an intentional error, so the user can not copy this map," said academics from Liverpool Joe Moran.
Meanwhile, a Google spokesman said although most of the information on their services at the guaranteed right, but sometimes there is also the possibility of error there.
"We continue to work to develop the quality and accuracy of information available on Google Maps and would appreciate feedback from users who helped us in developing this service. "The spokesman said.

He also added that their service users can directly report their problems to find the data providers and Google will immediately update it. LONDON.
