How High Will the Price of Oil Go This Time?

This is the VOA Special English Economics Report

Unrest in North Africa and the Middle East has pushed oil prices back into the news Prices have been rising at their fastest level since two thousand eight

Libya is not among the ten largest oil exporters But the rebellion against Libyan leader Moammar Gadhafi has reduced production, affecting the global market

This month, oil prices rose above one hundred dollars a barrel Prices went above one hundred forty-five dollars

a barrel in two thousand eight

The price of oil affects prices and demand for energy, plastics, farm chemicals and many other products made with petroleum

During the last week of February, Americans paid the second biggest weekly increase in gasoline prices in twenty years This young woman has to drive a long way to school, so high gas prices mean less money for other things

WOMAN: “I am a college student and I have to drive forty-five minutes to college, so it sucks.”

The United States has a Strategic Petroleum Reserve that contains more than seven hundred million barrels of oil President Obama could use some of this emergency supply to help ease fuel prices But intervening in the market could hurt oil production in the United States

Oil prices have been rising at a bad time, just as many economies have been recovering from the global

recession Also, several countries in the euro area are still struggling with debt crises

European Central Bank President Jean-Claude Trichet said last week that “strong vigilance” is needed to contain inflation That could mean raising interest rates which could hurt European countries heavily in debt

In the United States, higher fuel prices come just as General Motors and Chrysler show signs of recovery after their reorganizations

American car sales last month were twenty-seven percent higher than last February GM led all carmakers with

a forty-seven percent increase

High fuel prices reduce demand for big cars and trucks But economist George Magliano says this time, high prices may be good for carmakers

GEORGE MAGLIANO: “With gasoline prices higher, certain people might want to get a much more fuel-efficient vehicle and I don’t mean even a hybrid or an electric vehicle which they could do, but the gasoline vehicles get twenty-five, thirty percent better mileage today than they did three or four years ago.”

After Brain Study, New Questions About Mobile Phones

Posted by admin on May 8th, 2011 at 08:14am

This is the VOA Special English Health Report

How important is your mobile phone, better known to Americans as a cell phone?

MAN: “I use my phone all the time I’m always on my phone.”

WOMAN: “It’s kind of pretty much important to me because it’s like my life saver.”

WOMAN: “I need my cellphone.”

So far, no studies have proven beyond question that the radio signals from cellphones cause brain cancer or other health problems But a new study by government scientists in the United States has some people

wondering what to think

The scientists found that holding a cellphone to your ear for at least fifty minutes increases brain cell activity Even the scientists themselves are not sure about the meaning of their findings

Dr Nora Volkow led the study She heads the National Institute on Drug Abuse, part of the National Institutes

of Health Dr Volkow says she would not be concerned that fifty minutes of cellphone exposure would harm anyone But she says the research does show the need to study whether or there are long-lasting effects of repeated exposure over several years

Her team studied forty-seven healthy volunteers between January and December of two thousand nine The volunteers had cellphones placed against both ears while the scientists made images of their brain activity

As part of the test, one phone was activated but muted for fifty minutes The other phone was off After that, the people were tested with both phones turned off Dr Volkow says the brain scans showed increased activity in brain cells closest to the activated phone

NORA VOLKOW: “This right area of the brain that was very close to the antenna shows the largest increase in metabolism as compared when the telephones were off Even though the radio frequencies that are emitted from current cellphone technologies are very weak, they are able to activate the human brain to have an effect.” The scans showed how the brain cells used sugar to produce energy, a normal activity The activity was seven percent higher in areas of the brain closest to the cellphone antenna

The study appeared in the Journal of the American Medical Association

Experts say people who are concerned about mobile phones can take steps like using a wired headset

Dr Giuseppe Esposito is a nuclear medicine expert at Georgetown University Medical Center in Washington

He says after many years of studies, better kinds of research are still needed to settle questions about cellphone safety These studies would take years

GIUSEPPE ESPOSITO: “We need what are called epidemiological studies where you will follow a population using cellphones — high users or light users — and then see what happens over the years.”

Children at US School Show Their Support for Victims in Japan

Posted by admin on May 6th, 2011 at 04:16pm

This is the VOA Special English Education Report

Cranes are large birds with long legs and necks In Japan and other East Asian cultures, they represent luck and long life

Japanese tradition says a person who folds one thousand paper cranes gets the right to make a wish Some schoolchildren in the United States have been folding cranes They want to show they care about the victims of the March eleventh earthquake and tsunami in Japan

Almost forty Japanese-American students attend Somerville Elementary School in Ridgewood, New Jersey But all five hundred twenty-five students at the school have heard about the disasters So they have decorated their school with paper origami cranes Their wish is for a speedy recovery for the Japanese people

Art teacher Samantha Stankiewicz says the activity gives students a way to express empathy for victims

SAMANTHA STANKIEWICZ: “For children, the folding of the cranes has been a really positive way for them

to feel like they’re actively engaged, even though the cranes are symbolic.”

These students thought out loud as they folded cranes in the school library

BOY: “The crane is a symbol of hope, so we try to have a lot of hope for those people in Japan.”

GIRL: “It makes me feel really happy that everyone’s caring for another country.”

GIRL: “I feel sad for them, like really sad for them But I also feel happy for us, because we are really trying to help out.”

And that help is not just in the form of paper cranes The school principal, Lorna Oates-Santos, says children at Somerville Elementary have raised about two thousand dollars for disaster relief agencies

LORNA OATES-SANTOS: “We will be donating that money to the American Red Cross and Save the

Children They are two groups that are ready on the ground in Japan to help the people of Japan.”

The school has a television club that produces weekly programs on different subjects Fourth-grade teacher Gabrielle King is director of the club, and says the students are involved in the school’s efforts

GABRIELLE KING: “When the earthquake happened, the children wanted to know what they could do to inform other students and raise awareness for the people in Japan So, we decided to do a show on the

earthquake, and to also making the cranes, the origami cranes.”

Some American children have shown their feelings for the victims in Japan in other ways Yasuhisa Kawamura

is Japan’s deputy consul general in New York

YASUHISA KAWAMURA: “One American young girl dropped by the consulate a couple days ago with her own painting The painting shows the two countries, Japan and the United States, shaking hands over the ocean, and saying ‘We are with you.’ So, we are very, very moved and touched by this young girl’s expression.” And that’s the VOA Special English Education Report The East Asia Program at Cornell University in the United States has a lesson plan and directions for folding origami cranes You can find a link at

Future Payments for Retirees Are Big Issue Now for US States - English Listening Lessons.mp3

Future Payments for Retirees Are Big Issue Now for US States

Posted by admin on May 4th, 2011 at 11:08am

This is the VOA Special English Economics Report

State and local governments across the United States are facing big budget deficits Many of these shortfalls include promises of future retirement payments for public employees

Several states have had to borrow money for pension plans that have fallen below required funding levels Pay and benefits for public workers have been a target as state and local governments try to cut spending At the same time, there are efforts in several states to reduce the negotiating rights of public employees

In many cases, public employee unions have agreed to accept lower pay But they oppose efforts to limit

collective bargaining An effort by Republicans to do that in Wisconsin has led protesters to occupy the state capitol building

Almost every state requires a balanced budget Yet worries that state and local governments might not be able

to repay their debts are now adding to the costs of borrowing Illinois had to offer a high return of nearly six percent on bonds to be repaid by twenty nineteen

Experts say, on average, public employees are paid less but have better benefits than workers with similar skills

in private jobs However, they say these differences in labor costs are a lot less than some people think

Still, traditional pension plans pay a set amount for as long as a retiree lives States like Georgia, Michigan, Colorado and Ohio are considering a change for future employees They might offer retirement plans similar to what are called 401(k) plans

These are a common form of plan offered by private employers Employers and workers both put money into the plan Workers can invest the money in areas like stocks or bonds Their retirement savings are defined by the return on their investments in the plan

Federal workers already have a savings plan similar to a 401(k)

John McGlennon heads the Government Department at the College of William & Mary in Virginia He says the economic crisis of two thousand eight continues to affect state and local tax collections Also, many pension funds have less money because their investments have yet to fully recover from the recession But Professor McGlennon says things could change

JOHN McGLENNON: “In terms of the future, states are not necessarily going to be in a rosy condition in the next couple of years But they do tend to recover much more rapidly than we tend to anticipate.”

A Possible Safe New Way to Kill Mosquitoes That Spread Malaria

Posted by admin on April 29th, 2011 at 02:14pm

This is the VOA Special English Health Report

Israeli researchers say they have developed a substance that attracts and kills mosquitoes infected with the malaria parasite However, the sweet smelling substance is said to be harmless to people and animals

Scientists at Hebrew University in Jerusalem developed the sugary bait by combining fruit juice oils and boric acid The fruit juice gets the attention of the mosquitoes Boric acid kills the insects when they eat it

The scientists took the boric acid sweet bait to the West African nation of Mali They sprayed it on plants near man-made ponds Villagers use water from the ponds during the dry season But the area is also home to

Anopheles gambiae, the mosquito that carries the most deadly form of malaria

The researchers also placed a sweet-smelling spray on grasses near other ponds But that spray contained no boric acid

Both substances also contained a substance that would mark any mosquito that came in contact with it This way the scientists could count the mosquitoes that fed on the bait

Yosef Schlein is an expert on insects that affect human health Professor Schlein led the sweet bait research He says thirty-eight days of results show the sweet boric acid bait proved very effective at killing mosquitoes YOSEF SCHLEIN: “In Mali, we got down by some eighty percent, the females, and ninety percent of the males But the area is full of little ponds in there, so it is impossible to stop mosquitoes from flying from an untreated pond to a treated pond.”

At the ponds treated only with sweet-smelling bait, Professor Schlein says, more than seventy five percent of mosquitoes fed on the false bait He says most people do not know that female mosquitoes feed on sweet plant nectars to survive Their blood feedings are part of reproduction

The Israeli researchers now hope to develop a bait that is even more desirable to the malaria mosquitoes

Boric acid is generally safe for human beings and other mammals Professor Schlein says scientists might be able to develop a mosquito bait for enclosed spaces Boric acid has been used to kill other insects including cockroaches, termites and ants inside homes since the middle of last century

A report about the malaria mosquito sweet bait was published in Malaria Journal

Meet Some Top Students in the Intel Science Talent Search

Posted by admin on April 27th, 2011 at 02:13pm

This is the VOA Special English Education Report

The Intel Science Talent Search is the top science competition for high school students in the United States The forty finalists were honored in Washington last week They met with scientists and politicians President Obama welcomed them to the White House

These forty students were selected from almost two thousand contestants nationwide They had to present original research to be judged by professional scientists The students showed their research projects on large posters The winners were announced March fifteenth

Wendy Hawkins is executive director of the Intel Foundation She says the forty finalists represented excellence across many areas of science

WENDY HAWKINS: “These students bring work that is ready for publication and in many cases has already been published in pretty much any branch of science that you can think of: physics, electrical engineering And the projects are deep and rich and insightful.”

Selena Li is from Fair Oaks, California She wanted to find a more effective treatment for liver cancer She began her research four years ago A scientist at the University of California, Davis, taught her how to design and do experimental work in the laboratory

SELINA LI: “I researched a new approach to targeting liver cancer by basically starving the liver cancer cells to death, while leaving the normal cells unaffected And, to go one step further, I blocked a survival pathway to make the treatment more effective.”

Ms Li placed fifth in the Intel Science Talent Search and was awarded thirty thousand dollars

Scott Boisvert lives near Phoenix, Arizona He began using a laboratory at the University of Arizona at the age

of fourteen Over four years, he completed a project studying a fungus linked to the decrease in amphibians around the world

He was trying to find out if different chemicals and substances in the water could kill the fungus He collected and tested water samples across Arizona

SCOTT BOISVERT: “My results were able to identify a list of chemicals that were significant in the growth and in the movement of the fungus.”

He placed tenth in the Intel competition and was awarded twenty thousand dollars

Evan O’Dorney of Danville, California, won the top award of one hundred thousand dollars in this year’s Intel Science Talent Search For his mathematical project, he compared two ways to estimate the square root of an integer, a number with no fractional parts

Wendy Hawkins at the Intel Foundation says these young people represent the next generation of scientists who will help shape America’s future

Brain-Computer Interfaces Could Mean More Freedom for the Disabled - English Listening Lessons.mp3

Brain-Computer Interfaces Could Mean More Freedom for the Disabled

Posted by admin on April 23rd, 2011 at 02:11pm

This is the VOA Special English Technology Report

Since the nineteen seventies, scientists have been searching for ways to link the brain with computers Brain-computer interface, or BCI, technology could help people with disabilities send commands to machines

Recently, scientists demonstrated a small robotic vehicle directed by a person’s thoughts The demonstration took place at the Swiss embassy in Washington Jose Millan and Michele Tavella developed the system Mr Tavella can even talk as he watches the vehicle and guides it with his thoughts

MICHELE TAVELLA: “That’s very, very easy That’s the simplest part we could say because moving one hand or the other is a very, very common task There is no workload It’s very, very simple.”

Mr Tavella is a researcher at the Federal Polytechnic School in Lausanne, Switzerland In the laboratory, he can operate a wheelchair just by thinking about moving his left or right hand

Professor Millan is the team leader He says systems like those being developed in Lausanne and other places may be available in less than ten years

JOSE MILLAN: “The brain-machine interface is a system that allows disabled people, people suffering from physical disabilities to communicate with external world and also to control devices.”

Our brain has billions of nerve cells These send signals through the spinal cord to the muscles to give us the ability to move But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles

The researchers designed a special cap for the user This head cover captures the signals from the scalp and redirects them to a computer The computer interprets the signals and commands the motorized wheelchair The wheelchair also has two cameras that identify objects in its path They help the computer react to commands from the brain

Professor Millan says scientists keep improving the computer software that identifies brain signals and turns them into simple commands

JOSE MILLAN: “The practical possibilities that brain-machine interfaces offer to disabled people can be grouped in two categories: Communication, and controlling physical devices and virtual devices One example

is this wheelchair.”

He says his team has set two goals

JOSE MILLAN: “What we want is to bring this technology out of the lab and this has two components First is testing with real patients, so as to demonstrate that this is a feasible technology they can benefit from And the second aspect of that is to guarantee that they can use the technology over long periods of time.”
