Drought attack the world violently

Salt Lake City
Use water sparingly because the earth seems increasingly dry due to pollution and global warming. Langkanya water is now felt in some countries the United States and Australia who have always used since the lack of water, and is now worrying.Seven western U.S. states will face water shortages in some years, when climate change increasingly uncontrollable. Increasingly severe drought and the large population growth, making Colorado River victims. "Clearly we are visible in the imbalance between supply and demand," said Brad Udall, Director of Western Water Assessment from the University of Colorado.

Although there is debate about when the worst conditions will surge, scientists at a conference in Salt Lake City, Friday (5 / 12) yesterday estimate the water shortage would occur again in a few decades. "Without any major changes in the management of water, lack of results and the difficult situation will soon occur in seven countries because of the level of river water supplies that meet the increasingly receding," said Dave Wegner, director of the Glen Canyon Institute scientists, as the host-day conference at the University of Utah .

These changes are now clearly visible with the decrease in level of river flow, temperature, higher claims and the amount charged on the Colorado River. This river is very long stretches as far as 2,240 km and provide supplies for agriculture, business, urban and housing. This river along the routes serving Arizona, California, Colorado, Nevada, New Mexico, Wyoming and Utah region, which is inhabited by 30 million people.

Last year officials from seven states and Mendagri Dirk Kempthorne signed the agreement with the goals of conservation and rescue Colorado River. Long-term plan up to 20 years to set the cooperation deal with the drought.

Meanwhile, if the drought that the country had become increasingly concerned about kangaroos. State terkering local forced to buy water for the first time to meet the supply. Minister of Water Affairs said Karlene Maywald, South Australia to buy 61 billion gallons of water (231 gigaliter) to the capital city of Adelaide has enough water for the needs during 2009 despite continued drought strikes. "We must be careful in taking decisions and to buy water to meet the needs," said Maywald to the Australian Broadcasting Corp. radio.

Purchase this underscore the serious situation in South Australia. Some experts predict the state will run out of water at the end of the year 2008. They experienced a drought during the last five years and the storage of water Adelaide plunged 8 percent last year.

Make Success Spider Nest in Outer Space

Indeed astonishing that the spider is sent to the international outer space station (ISS) successfully make a nest. The success of this interesting to learn because the animals do so in the weightless space. "Two-tailed spider in the construction of an international outer space station has successfully overcome kebingungannya to weave a net that can be startling in zero gravity," said one of the astronauts, Friday (21 / 11) ago. Weaver spider was transported to the ISS early last week with the astronauts ride the plane back Saturday Endeavour. During a day in space, the spider is seen to create patterns that do not clear the net. However, a few days later the spider was successfully make the net regularly.
"We note the profit-making net profit of symmetrical. Truly beautiful," said Michael Fincke, ISS commander. He said the astronauts surprised to see how fast the spider adapting to outer space.
Delivery of the spider to the space is part of a scientific experiment intended to increase interest in school children learn science. Moreover, the type of spider that selected the same with the spider, which is used as characters in children's story book Charlotte's Web works EB White. Children will be asked to compare the form of a spider web created by the Earth are made in outer space.
In addition to the spider, the astronauts also took flyblow butterfly. Scientists from the University Colorado, Boulder, the U.S. will monitor its development, soon to become a butterfly adults. As a food spider, also brought the fruit fly. Meanwhile, for the butterfly center bermetamorfosis already provided adequate nectar.

Technology-> first biological Robot brain in the world

Teachers Large Field Cybernetics from the University of Reading, UK, Kevin Warwick, can not hide the taste bangganya. Robots clear from the biological nervous (neurons) rats as far as this gives hope.Gordon, as the name of robots, the robots is a biological brain in the first dunia.Gordon dijejali dozens of electrodes to capture electrical signals generated by the brain cells that. The biological brain consists of many neurons in a Multi-Electrode Array (MEA), which will mengomunikasikan and control the robot via a Bluetooth connection. The project is the first to know how the brain stores a specific data.

Each time Gordon approaching object, the signals are sent to make to avoid the collision. Biological brain instructs the wheels to turn right or left. So forth.

For Kevin, teaches at the School of Systems Engineering, a project worth almost half a million Pounds Sterling funded by the UK Engineering and Physical Sciences Research Council (EPSRC), the two members of surprises. First, how the brain is able to manipulate biological body robots. Second, the project is to help them examine further how the brain to learn and save a lot of experience.

"People will know how the brain works and it will impact on many things in the world of science and medicine," he said. The project started on January 1 2007 and will expire 31 December 2009.

Applications treatment

For the team, Gordon ability to move solely because biologisnya ability of the brain, not the end of the study. Furthermore, they learn the biological brain works tolerably complex, including a response to Gordon through the various signals.

From there, for example, the researchers will directly witness how bermanifestasi memories in the brain, when Gordon visited the territory which.

Understanding it believed would help the world understand more about the various diseases related to brain disturbance, such as Alzheimer's Disease, Parkinson, and stroke.

The behavior of complex

Pharmacist who is also member of the team, Ben Whalley, said, there is one fundamental question faced by scientists until now. Namely, how to explain regard the activity of individual neurons with the behavior of complex, as seen in many organisms.

For Ben, a project that gives them a unique opportunity to understand something, that shows the complex behaviors, but still close to the activities of individual neurons. "This gives us hope that the answers of the questions that was very fundamental."

In the world of robotics, the achievement of the team creator of the "Gordon" is the progress of efforts such as the kind done in the mid-2005.

When it inspired biological systems, the researchers developed a miniature robot capable himself up with the parts or materials from the surrounding environment.

Researchers have long faced the question of how cells can live mereplikasi DNA using materials that float is not uniform in the cell nucleus. Until now, such efforts continue.

Like Gordon, a miniature robot developed three years ago is also directed to realize the mistake and try to improve the error. The development of robots use living cells involves the team of researchers from the Massachusetts Institute of Technology (MIT).

Increased rapidly

The development of robots not only challenging for the researchers with the various development purposes. For the public, robot technology is the product of many sought and utilized.

2004, the annual survey of world robotics, held the UN mentioned, the use of robots for household and office reached seven times in the year 2007.

The types of robots that, among others, cutting the grass, vacuum cleaner, and cleaning windows. The end of 2003, recorded 607,000 automated tools used at the household level. The number of the new 2 / 3 of the total tool in that year.

The end of the year 2007, the amount increased to 4.1 million. Inhaler dust now ranked first tool is used, followed by rapid demand fluctuations window cleaning robots and pool cleaning.

In the field of robot toys, robot dog AIBO, Sony also made very attractive to consumers. A study noted, there are at least 692,000 robots entertainer (entertainment robots) in the world.

Replace the role of human

Slowly but surely, robots began to replace the role of human beings. From the previous work under the direct control of the user, the robot meaningful change: working with independent pascapemrograman computer.

In large companies, robots replace human tasks, such as in the field of product assembly. Now, it is estimated there are 21,000 kinds of industrial robots have been used (service robots) for various tasks, such as milk dairy cows, handling toxic waste and dangerous, to help operate the theaters.

According to a study, the end of this decade, robots not only clean the floors, cut grass, and keep the house, but also help the elderly and among people with disabilities. Robots are also provided, gentle bomb, extinguish the fire, and check the location of the dangerous man.

Progress technology enables robots to do many things previously unimaginable. Robot Gordon biological brain shows this invaluable, bridge the gulf between biology and technology. (arien novarian)

Youth If we think, only Sides See Only Senangnya


SEMARANG, SATURDAY - A psychologist from Semarang states, the average young child in Indonesia engaged in only see the side Beneath it, and do not see the other side."In the young, the average date they often do not see the other side, who only see the fun only. In addition, many young people are often engaged when eaten accidentally by the word love, the court healthy is not only based on love only," said dr. Hastaning Sakti, psychologist from the Psychology Faculty of Diponegoro University (Undip) Semarang in Semarang, Saturday.
Mba, so call akrabnya, said that when a speaker in the Road Show Diponegoro Care Center (DCC) on the campus of Psychology Undip. On this occasion he also complained about the young people engaged in this often when having sex to the outside marriage, which resulted in pregnancy that is not diinginkan.Selain, he added, should young children should see the impact due to poor sexual relationship free, as have HIV / AIDS, pregnancy, miscarriage, and other psychological impact. "So, if the rate steady not only from the side of good, should be viewed from all sides, including the relationships do not have sex outside of marriage," he reminded.

"Currently many cases because aborsi pregnant outside of marriage. This is because the court that the relationship is not healthy," said mba. Road show held by the DCC is also the problem of violence and reproductive health in the court.

According to Nuno, head of the steering committee, this activity is raising issues that are often faced by teenagers such as aborsi, violence in the court, and unwanted pregnancy, and drugs.

"In fact, similar events have been held either in schools, colleges, and community, but we're optimistic that this event will be influential for the participants in this event because the participants were invited to discussions and exchange opinions," he said.

DCC Events in the Faculty of Psychology is the first round of the event, which also planned to be held in all faculties at the Diponegoro University. "We plan to undertake a road show in all faculties at Undip, for activities outside the months yesterday we already hold in Central Java, East Java, Yogyakarta, Banten and West Java," said Nuno.
